By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `<wchar.h>' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. diff --git a/Build/source/utils/songs/songs-2.17/Makefile.am b/Build/source/utils/songs/songs-2.17/Makefile.am new file mode 100644 index 00000000000..98eb5c73f31 --- /dev/null +++ b/Build/source/utils/songs/songs-2.17/Makefile.am @@ -0,0 +1,10 @@ +SUBDIRS = src/songs src/songidx src/sbdchk sample src/vim + +distclean-local: + -test src/songs/songs.dtx -ef "${srcdir}/src/songs/songs.dtx" || rm -f src/songs/songs.dtx + -test sample/chordbook.tex -ef "${srcdir}/sample/chordbook.tex" || rm -f sample/chordbook.tex + -test sample/lyricbook.tex -ef "${srcdir}/sample/lyricbook.tex" || rm -f sample/lyricbook.tex + -test sample/slidebook.tex -ef "${srcdir}/sample/slidebook.tex" || rm -f sample/slidebook.tex + -test sample/transparencies.tex -ef "${srcdir}/sample/transparencies.tex" || rm -f sample/transparencies.tex + -test sample/songs.sbd -ef "${srcdir}/sample/songs.sbd" || rm -f sample/songs.sbd + diff --git a/Build/source/utils/songs/songs-2.17/NEWS b/Build/source/utils/songs/songs-2.17/NEWS new file mode 100644 index 00000000000..84aa406d3fa --- /dev/null +++ b/Build/source/utils/songs/songs-2.17/NEWS @@ -0,0 +1,369 @@ +Songs LaTeX Package Revision History: + +Version 2.17 [2013/07/10]: + + * Fixed a major error in the page-builder (introduced in v2.16 by the fix to \sclearpage) which caused the last page of many songs environments to be dropped.

The \interlinepenalty now defaults to 1000 and \vvpenalty and friends now default to 200. \spenalty defaults to 100. + + * Fixed a compatibility issue with Babel that caused \gtab to malfunction when French was the active language + + * Fixed a bug that caused overthick division bars between songs when \sbarheight was set larger than 1pt + + * Fixed a bug that caused the song-positioning algorithm to underestimate the size of songs containing auto-repeated choruses. + + * Re-fixed a returning bug that caused spurious hyphenation when an \echo part ended with a chord longer than its lyric. + +Version 2.8 [2009/03/14]: + + * \songnumstyle and \versenumstyle replaced with \thesongnum and \theversenum macros (for compatibility with standard LaTeX counters) + + * \label's within a song or numbered verse can now be used to create automatic references to the song's or the verse's number. + + * Using \showindex with \includeonlysongs now yields a partial index instead of a full index. + + * New \indexsongsas macro can customize indexes to print page numbers instead of song numbers. + + * Index fonts now customizable with \idxheadfont, \idxtitlefont, \idxlyricfont, \idxscripfont, \idxauthfont, and \idxrefsfont. + + * Formatting of scripture index book names is now customizable with \idxbook. + + * \showindex now takes an optional argument to specify the number of columns. + + * Index typesetting logic improved to handle index entries whose left-hand-sides exceed the width of the column + +Version 2.7 [2009/01/08]: Third CTAN release + + * Constructions like "\[A]\[B]\[C]lyric" now typeset the same as "\[A B C]lyric", but the chords in the sequence can be replayed separately (e.g., with "^^^lyric"). + + * Added support for begin- and end-repeat signs (\lrep and \rrep). + + * Column and page breaks can now be inserted into partial song lists created with \includeonlysongs. + + * Fixed a bug that caused sharp symbols to be doubled within echo parts on eTeX. + +Version 2.6 [2008/04/02]: + + * \newchords and \replay macros added, optional argument added to \memorize + + * new "Quick Chords" mode for Vim users to make chord-entry a snap + + * Windows uninstaller reworked to avoid deleting files modified since installation + + * Last pages of multicolumn indexes are now vertically balanced. + + * Fixed a bug that occasionally produced empty pages when \topskip was non-zero + + * Fixed a bug that produced duplicate verse numbers when the first line of a verse was contained in a group + + * \echo macro no longer introduces a spurious line-break on eTeX. + + * \DeclareLyricChar and friends now perform macro-tests based on macro name rather than macro definition. + + * Extended mark register classes are now allocated safely so as to cooperate with other eTeX-aware packages. + +Version 2.5 [2008/02/08]: + + * Unix version now uses the GNU automake system to configure and build itself + + * Support for more than two columns added (use \songcolumns to set the number of columns). + + * Chord replaying system now works properly in choruses. + + * Added \stitlefont to allow users to customize the song title font without having to redefine \makeprelude. + + * Added \baselineadj to allow users to customize the \baselineskip without having to redefine \everychorus and \everyverse. + + * Superscript ("^") now works again in math mode even when chord replaying system is active. (It can therefore be used to typeset chord names if desired.) + + * hyphchk utility renamed to sbdchk + + * sbdchk utility updated to report column numbers in reports and error messages + + * sbdchk and songidx sources updated to better adhere to GNU coding standards + +Version 2.4 [2007/10/09]: Second CTAN release + + * Added \titleprefixword, \authsepword, \authbyword, \authignoreword, and \idxcont to support automatic index-generation for non-English languages. + + * songidx program now supports piping to/from stdin/stdout (specify a filename of "-" to use this feature) and will infer an output filename when none is specified on the command line. + + * Unix makefiles and Windows batch files for the sample books have been updated to allow users to add new indexes without changing any of the make/batch files. + +Version 2.3 [2007/09/23]: + + * \indexentry and \indextitleentry now accept an optional argument specifying which indexes to add the new entry to (overriding the defaults for the current songs environment) + + * \ch and \mch macros can now replay chords by using "^" as the chord name + + * Renamed the .dat and .tex intermediate files produced during index generation to .sxd (Song indeX Data) and .sbx (Song Book indeX), respectively, to avoid conflicts with other software. Unix users can now write Makefiles that recognize these unique file extensions. + +Version 2.2 [2007/08/09]: + + * The page-layout algorithm now honors \maxdepth, fixing a bug that occasionally produced overfilled vbox warnings during output. + + * Fixed compiler warnings for systems that won't implicitly cast between integer and wide-characters. + +Version 2.1 [2007/08/02]: + + * "Overheads" mode renamed to "slides" to reflect some substantial changes to that mode (see below). + + * \sepverses can now be used in slides mode to put each verse and chorus on a separate slide. This seems to be the norm in churches that use a digital projector, since it allows worship leaders to repeat previous verses or choruses without having extraneous lyrics up on the screen. + + * Choruses in slides mode are no longer surrounded by vertical rules, but are instead italicized by default. The rules looked nice, but they made it impossible to correctly break large choruses that couldn't fit on a single slide. + + * To make echo parts stand out in italicized choruses, \echo now toggles between oblique and upright shapes (like \emph) instead of forcing the former. + + * \repchoruses can now be used to repeat choruses automatically in songs that span more than one slide. This is very useful when creating foils for an overhead projector. + + * \versemark and \chorusmark added to allow page headers that match the current verse or chorus rather than just the current song. + + * \everyverse and \everychorus added so that users can make choruses begin with "Chorus:" and the like if they wish. (Personally I think that wastes too much space, but it's a common style.) + + * \ifvnumbered conditional added to allow code that checks to see if the current verse is numbered or not. + + * New \begin...only and \begin...never conditionals introduced that are just like \if... and \if...\else except that they avoid certain "runaway argument" errors raised by the latter. + + * Added \versefont, \chorusfont, \versejustify, and \chorusjustify to allow users to customize font and/or justification of verses and choruses all independently. This reduces slides mode to a set of customizations that can all be manually duplicated (or undone) by the user. + + * \baselineskip logic improved to better handle large fonts. + + * Indexes now work properly when using \includeonlysongs to generate a partial list. + + * \brk can now be used in vertical mode to suggest column- and page-breaks in verses and choruses that are too long to fit on a single slide. + + * Added \DeclareNonLyric and \DeclareNoHyphen for better support of \inputenc. + + * \tablature macro shortened to \gtab and with only two mandatory arguments instead of four. + + * Automatic transposition now recognizes alternate note names, such as solfedge note names. + +Version 2.0 [2007/06/20]: + + * Introduced keyval syntax for \beginsong. + + * Added chord-replaying system (^, \memorize, \[^...]). + + * Removed in-package code that loads hyperref. Users must now load hyperref manually. + + * \songsection and \songchapter now support optional arguments like \section and \chapter do. + + * Non-output-producing tokens (like \relax) can now appear between the last \Acolon or \Bcolon line and the \endscripture line without messing up the scripture citation that gets appended to the last line. + + * Fewer macros are declared \outer, allowing authors to embed them within their own macro definitions. + + * Lyric-scanner code is now faster. + + * songidx was not recognizing apostrophes as intra-word characters. + + * When a guitar tablature diagram with a fret number appeared above a lyric, subsequent chords that did not include tablature diagrams were being spaced incorrectly (as if they had invisible fret numbers). + + * Fixed a bug that caused songs environments to occasionally generate pages slightly larger than \textheight. + +Version 1.22 [2007/05/15]: First CTAN release + + * \chordson and \chordsoff modified to update interline spacing, so that they can now be used within a song. + + * \MultiwordChords added to allow spaces to be included under chords. + + * \DeclareLyricChar added to allow user-specified macros to be treated as lyric characters. + + * Added support for UTF-8 encoded source files. + +Version 1.21 [2006/09/17]: + + * Changed \rep so that it does not enter math mode when making the "times" symbol. (This helps quell missing font size warnings.) + + * \echo now preserves existing font selection and merely italicizes it. + +Version 1.20 [2006/03/12]: + + * Added \noversenumbers to turn off automatic verse numbering + +Version 1.19 [2005/10/24]: + + * Added book sectioning commands (\songchapter and \songsection). + + * Fixed song numbering so that it now starts at 1 by default in each song section. + +Version 1.18 [2005/09/29]: + + * Automatic verse numbering added. + +Version 1.17 [2005/09/24]: First release as a style package instead of a class + + * Code massively reorganized to function as a .sty package instead of a .cls class. + + * Added \songmark so that users can add marks to affect page headers/footers + +Version 1.16 [2005/07/23]: + + * First rollout of the new \[] syntax for producing chords. Lyrics are parsed as an implicit second argument. + +Version 1.15 [2005/05/26]: + + * Added song title iterators: \songtitle, \songtitletoks, \nexttitle, \foreachtitle, \resettitles + + * Added \makeprelude and \makepostlude to allow users to customize song headers/footers + +Version 1.14 [2005/05/15]: + + * Introduced the scripture reference parser, to prevent odd linebreaks in scripture references. + + * Choruses now stretch and shrink like verses do. + +Version 1.13 [2005/05/12]: + + * Added kerning correction for double-quote ligatures in the Zaph Chancery font. + + * Added \Acolon, \Bcolon, and \strophe for typesetting biblical poetry. + + * Chords now preserve the \spacefactor so that subsequent text is spaced appropriately. + +Version 1.12 [2005/05/10]: + + * Redid intra-song spacing and penalties to eliminate superfluous vbox items. Improved performance. + + * Improved inter-song penalties for better page- and column-breaking. + + * \parindent now controls the amount of indentation for wrapped lines within a song or scripture. + + * Multiline textnotes now work right. + + * Fixed chord macros to avoid introducing hyphenation when lyric ends in punctuation. + +Version 1.11 [2005/04/21]: Begin tracking revision history + + * Renamed various macros to avoid naming clashes with other packages. + + * Adjusted the \\ index-separator macro so that its scope is now limited to the indexes. + +Version 1.1 [2005/04/03]: First release as a .cls documentclass + + * First release as a self-documenting .dtx file + +Version 1.0 [2001/12/01]: Initial release diff --git a/Build/source/utils/songs/songs-2.17/README b/Build/source/utils/songs/songs-2.17/README new file mode 100644 index 00000000000..049e7d0d591 --- /dev/null +++ b/Build/source/utils/songs/songs-2.17/README @@ -0,0 +1,200 @@ +------------------------------------------------------------------------------ + Songs LaTeX Package Documentation +------------------------------------------------------------------------------ + +Table Of Contents: + I.

Creating a New Song Book + D. Support Utilities (songidx and sbdchk) + VI. Removal / Reinstallation + VII. Help and Support + + +I. Overview + +The Songs package is for producing songbooks containing lyrics and chords +(but not sheet music). Each songs document can produce a lyric-only songbook +for singers, a chorded songbook for musicians, a set of overhead +transparencies, or a set of digital projector slides, all from a single master +document. It can also automatically generate partial songbooks consisting of +only some songs from the master document in a specified order. Facilities for +automatic transposition and creation of guitar tablature diagrams are also +included. + + +II. Copyright Notice + +The songs LaTeX package is copyright (C) 2013 Kevin W.

System Requirements + +In order to install and run this software, you will need: + +1. a C compiler (included on all Unix systems), +2. a LaTeX2e installation (by default, the installation tries "pdflatex"), +3. tar and gzip programs (to unpack the songs-x.xx.tar.gz file), and +4. an installation of GNU Make (to run the Makefile). + + +IV. Installation Instructions + +1. Unpack the songs-x.xx.tar.gz file (where x.xx is the version number). + + tar -xzf songs-x.xx.tar.gz + +2. Change directory to the songs directory and run the configure script. + + cd songs-x.xx + ./configure + +3. Run GNU Make (other versions of Make are not supported). To be sure that +you are using GNU Make and not some other version of Make, use the "gmake" +command: + + gmake + +4. If you only intend to use the software by editing files within the +songs-x.xx directory tree (i.e., a single-user installation), then you don't +need to perform the following final step. However, to allow other users to +access the software or to build song books yourself in other directories, you +must next install the binary programs, LaTeX style files, index data files, +and Vim support scripts in appropriate places on your system. To do so, make +the "install" target and specify a directory prefix equal to a fresh sub- +directory in your home directory: + + gmake install prefix=~/mysongs + +This will create a ~/mysongs directory tree containing the files that need to +be installed. Here is a summary of what it contains: + + bin: Contains executable programs. + share/doc: Contains package documentation. + share/texmf: Contains the main LaTeX style file. + share/songs: Contains the *.can data files used by songidx when + generating scripture indexes. + share/vimfiles: Contains support scripts for Vim (optional). + +Each of these must be copied to an appropriate place on your system. For +example, the following commands copy the files to appropriate places in a +typical /usr/local tree: + + cp ~/mysongs/bin/* /usr/local/bin + cp -r ~/mysongs/share/doc/songs /usr/local/share/doc + cp -r ~/mysongs/share/songs /usr/local/share + cp -r ~/mysongs/share/texmf/tex /usr/local/texmf + cp -r ~/mysongs/share/vimfiles/* /usr/local/share/vim/vimfiles + +Alternatively, the following copies them to appropriate places in a typical +single-user home directory structure: + + cp ~/mysongs/bin/* ~/bin + cp -r ~/mysongs/share/doc/songs ~/doc + cp -r ~/mysongs/share/songs ~/data + cp -r ~/mysongs/share/texmf/tex ~/localtexmf + cp -r ~/mysongs/share/vimfiles/* ~/.vim + +Note: After copying new files into the texmf tree, many LaTeX distributions +require you to execute the texhash command to update LaTeX's file name +database. Be sure to do so if your version of LaTeX requires it: + + texhash + + +V. Usage + +After running "gmake" from the songs-x.xx directory (step 3 above) you should +find the following file clusters: + +A. LaTeX Package Style File and Documentation + +In songs/src/songs you will find: +* src/songs/songs.sty: If you don't use "gmake install" to install this LaTeX + style file in the system's TeX repository tree, then songs.sty must be copied + into each directory that has a .tex file that uses the songs package. (This + is done automatically by the makefile that generates the sample book, so if + you reuse that makefile as recommended in part C below, you don't need to + copy it manually.) +* src/songs/songs.pdf: Comprehensive documentation of the songs package. + +B. Sample Song Books + +The GNUmakefile in songs/sample generates the sample song books. There are +four books in total: + +* sample/chordbook.pdf: a chord book for musicians, +* sample/lyricbook.pdf: a lyric book for singers, +* sample/slidebook.pdf: a book of slides for use with a digital projector, and +* sample/transparencies.pdf: book of transparencies for an overhead projector + +All four books draw upon the song data contained in the file songs.sbd. By +modifying that file, you can change the content of all four books. To change +the formatting style of any particular book, change the corresponding +sample/*.tex file. + +C. Creating a New Song Book + +You can create a new song book directory by copying the sample directory and +its contents to a new subdirectory: + + cp -r sample mybook + cd mybook + gmake clean + gmake + +If you have used "gmake install" to install the software (see Section III.4) +then your new "mybook" directory can be located anywhere; otherwise it must be +in the songs-x.xx directory. + +D. Support Utilities (songidx and sbdchk) + +* songs/src/songidx/songidx: This program is required for auto-generating song + book indexes. The GNUmakefile in songs/sample invokes it automatically as + necessary. +* songs/src/sbdchk/sbdchk: The sbdchk program is a utility that proofs .sbd + files for chord placement errors. Chords are misplaced if they fall at an + invalid hyphenation point or they break a ligature. To use sbdchk with the + sample song books, change to the songs/sample directory and type + + gmake sbdcheck + + This will generate a report file named songs.hyp in the current directory. + + +VI. Removal / Reinstallation + +To reverse the behavior of "make install", type: + + gmake uninstall + +To merely delete all generated files within the songs directory (without +deleting the non-generated files), type: + + gmake clean + + +VII.

Figure~\ref{fig:sample}. +% The page shown in that figure is from a chorded version of the book. +% When generating a lyric version, the chords are omitted. +% See \S\ref{sec:options} for information on how to generate different +% versions of the same book. +% +% \section{Initialization and Options}\label{sec:options} +% +% Each \LaTeX{} document that uses the \Songs{} package should contain a +% line like the following near the top of the document: +% +% \begin{codeblock} +% |\usepackage[|\meta{options}|]{songs}| +% \end{codeblock} +% +% \noindent +% Supported \meta{options} include the following: +% +% \paragraph{Output Type.} +% \DescEnv{lyric} +% \DescEnv{chorded} +% \DescEnv{slides} +% \DescEnv{rawtext} +% The \Songs{} package can produce four kinds of books: lyric books, chord +% books, books of overhead slides, and raw text output. +% You can specify which kind of book is to be produced by specifying one of +% |lyric|, |chorded|, |slides|, or |rawtext| as an option. +% If none of these are specified, |chorded| is the default. +% +% Lyric books omit all chords, whereas chord books include chords and +% additional information for musicians (specified using \mac{musicnote}). +% Books of overhead slides omit all chords and typeset +% one song per page in a large font, centered. +% +% Raw text output yields an ascii text file named \meta{jobname}|.txt| +% (where \meta{jobname} is the root filename) containing lyrics without chords. +% This can be useful for importing song books into another program, such as a +% spell-checker. +% +% \DescMacro{chordson} +% \DescMacro{chordsoff} +% Chords can be turned on or off in the middle of the document +% by using the |\chordson| or |\chordsoff| macros. +% +% \DescMacro{slides} +% Slides mode can be activated in the middle of the document by using the +% |\slides| macro. +% For best results, this should typically only be done in the document +% preamble or at the beginning of a fresh page. +% +% \paragraph{Measure Bars.} +% \DescEnv{nomeasures} +% \DescEnv{showmeasures} +% \DescMacro{measureson} +% \DescMacro{measuresoff} +% The \Songs{} package includes a facility for placing measure bars in chord +% books (see \S\ref{sec:measures}). +% To omit these measure bars, use the |nomeasures| option; +% to display them, use the |showmeasures| option (the default). +% Measure bars can also be turned on or off in the middle of the document by +% using the |\measureson| or |\measuresoff| macros. +% +% \paragraph{Transposition.} +% \DescEnv{transposecapos} +% The |transposecapos| option changes the effect of the \mac{capo} macro. +% Normally, using |\capo{|\meta{n}|}| within a song environment produces a +% textual note in chord books that suggests the use of a guitar capo on fret +% \meta{n}. +% However, when the |transposecapos| option is active, these textual notes +% are omitted and instead the effect of |\capo{|\meta{n}|}| is the +% same as for \mac{transpose}|{|\meta{n}|}|. +% That is, chords between the \mac{capo} macro and the end of the song are +% automatically transposed up by \meta{n} half-steps. +% This can be useful for adapting a chord book for guitarists to one that can +% be used by pianists, who don't have the luxury of capos. +% See \S\ref{sec:notes} and \S\ref{sec:transpose} for more information on the +% \mac{capo} and \mac{transpose} macros. +% +% \paragraph{Indexes.} +% \DescEnv{noindexes} +% \DescMacro{indexeson} +% \DescMacro{indexesoff} +% The |noindexes| option suppresses the typesetting of any in-document indexes. +% Display of indexes can also be turned on or off using the |\indexeson| and +% |\indexesoff| macros. +% +% \DescEnv{nopdfindex} +% PDF bookmark entries and hyperlinks can be suppressed with the |nopdfindex| +% option. +% For finer control of PDF indexes, see \S\ref{sec:idxcust}. +% +% \paragraph{Scripture Quotations.} +% \DescEnv{noscripture} +% \DescMacro{scriptureon} +% \DescMacro{scriptureoff} +% The |noscripture| option omits scripture quotations (see +% \S\ref{sec:scripture}) from the output. +% You can also turn scripture quotations on or off in the middle of the +% document by using |\scriptureon| or |\scriptureoff|, respectively. +% +% \paragraph{Shaded Boxes.} +% \DescEnv{noshading} +% The |noshading| option causes all shaded boxes, such as those that surround +% song numbers and textual notes, to be omitted. +% You might want to use this option if printing such shaded boxes causes +% problems for your printer or uses too much ink. +% +% \paragraph{Partial Song Sets.} +% \DescMacro{includeonlysongs} +% Often it is useful to be able to extract a subset of songs from the master +% document---e.g.~to create a handout or set of overhead slides for a specific +% worship service. +% To do this, you can type |\includeonlysongs{|\meta{songlist}|}| in the +% document preamble (i.e., before the |\begin{document}| line), where +% \meta{songlist} is a comma-separated list of the song numbers to include. +% For example, +% +% \begin{codeblock} +% |\includeonlysongs{37,50,2}| +% \end{codeblock} +% +% \noindent +% creates a document consisting only of songs 37, 50, and 2, in that order. +% +% Partial books generated with |\includeonlysongs| omit all scripture +% quotations (\S\ref{sec:scripture}), and ignore uses of +% \mac{nextcol}, \mac{brk}, \mac{sclearpage}, and \mac{scleardpage} +% between songs unless they are followed by a star (e.g., \mac{nextcol}|*|). +% To force a column- or page-break at a specific point in a partial book, +% add the word |nextcol|, |brk|, |sclearpage|, or |scleardpage| at the +% corresponding point in the \meta{songlist}. +% +% The |\includeonlysongs| macro only reorders songs within each +% \env{songs} environment (see \S\ref{sec:songs}), not between different +% \env{songs} environments. +% It also cannot be used in conjunction with the \env{rawtext} option. +% +% \section{Book Sections}\label{sec:sections} +% +% \paragraph{Section Titles.} +% \DescMacro{songsection} +% \DescMacro{songchapter} +% Section titles in a song book can be produced with +% +% \begin{codeblock} +% |\songsection{|\meta{title}|}| +% \end{codeblock} +% +% \noindent +% which acts like \LaTeX's |\section| command except that it centers +% the \meta{title} text in sans serif font and omits the section number. +% When using the |book| document class, use |\songchapter| +% instead of |\songsection|. +% +% \paragraph{Indexes.} +% \DescMacro{newindex} +% \DescMacro{newauthorindex} +% \DescMacro{newscripindex} +% The \Songs{} package supports three kinds of indexes: indexes by title and/or +% notable lyrics, indexes by author, and indexes by scripture reference. +% To generate an index, first declare the index in the document preamble +% (i.e., before the |\begin{document}| line) with one of the following: +% +% \begin{codeblock} +% |\newindex{|\meta{id}|}{|\meta{filename}|}| +% |\newauthorindex{|\meta{id}|}{|\meta{filename}|}| +% |\newscripindex{|\meta{id}|}{|\meta{filename}|}| +% \end{codeblock} +% +% \noindent +% The \meta{id} should be an alphabetic identifier that will be used to +% identify the index in other macros that reference it. +% The \meta{filename} should be a string that, when appended with an +% extension, constitutes a valid filename on the system. +% Auxiliary files named \meta{filename}|.sxd| and \meta{filename}|.sbx| +% are generated during the automatic index generation process. +% For example: +% +% \begin{codeblock} +% |\newindex{mainindex}{idxfile}| +% \end{codeblock} +% +% \noindent +% creates a title index named ``|mainindex|'' whose data is +% stored in files named |idxfile.sxd| and |idxfile.sbx|. +% +% \DescMacro{showindex} +% To display the index in the document, use: +% +% \begin{codeblock} +% |\showindex[|\meta{columns}|]{|\meta{title}|}{|\meta{id}|}| +% \end{codeblock} +% +% \noindent +% where \meta{id} is the same identifier used in the \mac{newindex}, +% \mac{newauthorindex}, or \mac{newscripindex} command, and where +% the \meta{title} is the title of the index, which should consist only of +% simple text (no font or formatting macros, since those cannot be used in +% pdf bookmark indexes). +% The |[|\meta{columns}|]| part is optional; if specified it dictates the +% number of columns if the index can't fit in a single column. +% For example, for a 2-column title index, write: +% +% \begin{codeblock} +% |\showindex[2]{Index of Song Titles}{mainindex}| +% \end{codeblock} +% +% \section{Compiling}\label{sec:compiling} +% +% As with a typical \LaTeX{} document, compiling a song book document requires +% three steps. +% First, use \LaTeX{} (|pdflatex| is recommended) to generate auxiliary files +% from the |.tex| file: +% +% \begin{codeblock} +% |pdflatex mybook.tex| +% \end{codeblock} +% +% Second, use the |songidx| program to generate an index for each index that +% you declared with \mac{newindex}, \mac{newauthorindex}, or +% \mac{newscripindex}. +% The syntax of the |songidx| command is: +% +% \begin{codeblock} +% |songidx |[|-b| \meta{canon}|.can|] \meta{filename}|.sxd| \meta{filename}|.sbx| +% \end{codeblock} +% +% \noindent +% where \meta{filename} is the same \meta{filename} that was used in the +% \mac{newindex}, \mac{newauthorindex}, or \mac{newscripindex} macro. +% If the index was declared with \mac{newscripindex}, then the |-b| option +% is used to specify which version of the bible you wish to use as a basis +% for sorting your scripture index. +% The \meta{canon} part can be any of the |.can| files provided with +% the |songidx| distribution. +% If you are using a Protestant, Catholic, or Greek Orthodox Christian bible +% with book names in English, then the |bible.can| canon file should work +% well. +% For other bibles, you should create your own |.can| file by copying and +% modifying one of the existing |.can| files. +% +% For example, if your song book |.tex| file contains the lines +% +% \begin{codeblock} +% \mac{newindex}|{titleidx}{titlfile}| +% \mac{newauthorindex}|{authidx}{authfile}| +% \mac{newscripindex}|{scripidx}{scrpfile}| +% \end{codeblock} +% +% \noindent +% then the commands to generate indexes sorted according to a Christian +% English bible are: +% +% \begin{codeblock} +% |songidx titlfile.sxd titlfile.sbx| +% |songidx authfile.sxd authfile.sbx| +% |songidx -b bible.can scrpfile.sxd scrpfile.sbx| +% \end{codeblock} +% +% Once the indexes are generated, generate the final book by invoking +% \LaTeX{} one more time: +% +% \begin{codeblock} +% |pdflatex mybook.tex| +% \end{codeblock} +% +% \section{Songs}\label{sec:songs} +% +% \subsection{Beginning a Song} +% +% \paragraph{Song Sets.} +% \DescEnv{songs} +% Songs are contained within |songs| environments. +% Each |songs| environment begins and ends with: +% +% \begin{codeblock} +% |\begin{songs}{|\meta{indexes}|}| +% $\vdots$ +% |\end{songs}| +% \end{codeblock} +% +% \noindent +% \meta{indexes} is a comma-separated list of index identifiers +% (the \meta{id}'s specified with \mac{newindex})---one identifier +% for each index that is to include songs in this song set. +% Between the |\begin{songs}| and |\end{songs}| lines of +% a song section can appear only songs (see below) +% or inter-song environments (see \S\ref{sec:between}). +% No text in a |songs| environment may lie outside of these environments. +% +% \paragraph{Songs.} +% \DescMacro{beginsong} +% \DescMacro{endsong} +% A song begins and ends with: +% +% \begin{codeblock} +% |\beginsong{|\meta{titles}|}[|\meta{otherinfo}|]| +% $\vdots$ +% |\endsong| +% \end{codeblock} +% +% \noindent +% Songs should appear only within \env{songs} environments (see above) +% unless you are supplying your own page-builder (see \S\ref{sec:layout}). +% +% In the \mac{beginsong} line, \meta{titles} is one or more song titles +% separated by |\\|. +% If multiple titles are provided, the first is typeset normally +% atop the song and the rest are each typeset in parentheses on +% separate lines. +% +% The |[|\meta{otherinfo}|]| part is an optional comma-separated list of +% key-value pairs (keyvals) of the form \meta{key}|=|\meta{value}. +% The possible keys and their values are: +% +% \medskip +% \noindent\hfil\vbox{\halign{#\hfil&\kern2em{\it#}\hfil\cr +% |by={|\meta{authors}|}|&authors, composers, and other contributors\cr +% |cr={|\meta{copyright}|}|©right information\cr +%

|ititle={|\meta{title}|}|&an extra index entry for a hidden title\cr}} +% \medskip +% +% \noindent +% For example, a song that begins and ends with +% +% \begin{codeblock} +% |\beginsong{Title1 \\ Title2}[by={Joe Smith}, sr={Job 3},| +% | cr={\copyright~|\unskip\expandafter|\the\year|| XYZ.}, li={Used with permission.}]| +% |\endsong| +% \end{codeblock} +% +% \noindent looks like +% +%

\end{sample} +% +% The four keyvals used in the above example are described in detail in the +% remainder of this section; +% the final two are documented in \S\ref{sec:ientry}. +% You can also create your own keyvals (see \S\ref{sec:newkey}). +% +% \paragraph{Song Authors.} +% \DescEnv{by=} +% The |by={|\meta{authors}|}| keyval lists one or more authors, +% composers, translators, etc. +% An entry is added to each author index associated with the current +% \env{songs} environment for each contributor listed. +% Contributors are expected to be separated by commas, semicolons, or the +% word |and|. +% For example: +% +% \begin{codeblock} +% |by={Fred Smith, John Doe, and Billy Bob}| +% \end{codeblock} +% +% \noindent +% Words separated by a macro-space (\verb*@\ @\eat*) or tie (|~|) +% instead of a regular space are treated as single words by the indexer. +% For example, \verb*@The Vienna Boys' Choir@\eat* is indexed as +% ``Choir, The Vienna Boys'\thinspace'' but +% \verb*@The Vienna\ Boys'\ Choir@\eat* is indexed as +% ``Vienna Boys' Choir, The''. +% +% \paragraph{Copyright Info.} +% \DescEnv{cr=} +% The |cr={|\meta{copyright}|}| keyval specifies the copyright-holder of the +% song, if any. +% For example: +% +% \begin{codeblock} +% |cr={\copyright~2000 ABC Songs, Inc.}| +% \end{codeblock} +% +% \noindent +% Copyright information is typeset in fine print at the bottom of the song. +% +% \paragraph{Licensing Info.} +% \DescEnv{li=} +% \DescMacro{setlicense} +% Licensing information is provided by |li={|\meta{license}|}|, where +% \meta{license} is any text. +% Licensing information is displayed in fine print under the song just +% after the copyright information (if any). +% Alternatively, writing |\setlicense{|\meta{license}|}| anywhere between +% the \mac{beginsong} and \mac{endsong} lines is equivalent to using +% |li={|\meta{license}|}| in the \mac{beginsong} line. +% +% When many songs in a book are covered by a common license, it is +% usually convenient to create a macro to abbreviate the licensing +% information. +% For example, if your organization has a music license from Christian +% Copyright Licensing International with license number 1234567, you might +% define a macro like +% +% \begin{codeblock} +% |\newcommand{\CCLI}{(CCLI \#1234567)}| +% \end{codeblock} +% +% \noindent +% Then you could write |li=\CCLI| in the \mac{beginsong} line of each song +% covered by CCLI. +% +% \paragraph{Scripture References.} +% \DescEnv{sr=} +% The \Songs{} package has extensive support for scripture citations and +% indexes of scripture citations. +% To cite scripture references for the song, use the keyval +% |sr={|\meta{refs}|}|, where \meta{refs} is a list of scripture +% references. +% Index entries are added to all scripture indexes associated +% with the current \env{songs} environment for each such reference. +% The |songidx| index generation program expects \meta{refs} to be a list +% of references in which semicolons are used to separate references to +% different books, and commas are used to separate references to to +% different chapters and verses within the same book. +% For example, one valid scripture citation is +% +% \begin{codeblock} +% |sr={John 3:16,17, 4:1-5; Jude 3}| +% \end{codeblock} +% +% The full formal syntax of a valid \meta{refs} argument is given in +%

\caption{Formal syntax rules for song scripture references}\label{fig:srsyntax} +% \end{figure} +% In those syntax rules, \meta{chapter} and \meta{verse} stand for arabic +% numbers denoting a valid chapter number for the given book, and a valid +% verse number for the given chapter, respectively. +% Note that when referencing a book that has only one chapter, +% one should list only its verses after the book name +% (rather than |1:|\meta{verses}). +% +% \subsection{Verses and Choruses} +% +% \paragraph{Starting A Verse Or Chorus.} +% \DescMacro{beginverse} +% \DescMacro{endverse} +% \DescMacro{beginchorus} +% \DescMacro{endchorus} +% Between the \mac{beginsong} and \mac{endsong} lines of a song can +% appear any number of verses and choruses. +% A verse begins and ends with: +% +% \begin{codeblock} +% |\beginverse| +% $\vdots$ +% |\endverse| +% \end{codeblock} +% +% \noindent and a chorus begins and ends with: +% +% \begin{codeblock} +% |\beginchorus| +% $\vdots$ +% |\endchorus| +% \end{codeblock} +% +% \noindent +% Verses are numbered (unless \mac{noversenumbers} has been used to +% suppress verse numbering) whereas choruses have a vertical line placed to +% their left. +% +% To create an unnumbered verse, begin the verse with |\beginverse*| instead. +% This can be used for things that aren't really verses but should be +% typeset like a verse (e.g.~intros, endings, and the like). +% A verse that starts with |\beginverse*| should still end with |\endverse| +% (not |\endverse*|). +% +% Within a verse or chorus you should enter one line of text for +% each line of lyrics. +% Each line of the source document produces a separate line in the resulting +% document (like \LaTeX's |\obeylines| macro). +% Lines that are too long to fit are wrapped with hanging indentation +% of width |\parindent|. +% +% \paragraph{Repeating Choruses.} +% \DescMacro{repchoruses} +% When making overhead slides, it is often convenient to repeat the song's +% chorus after the first verse on each page, so that the projector-operator +% need not flip back to the first slide each time the chorus is to be sung. +% You can say |\repchoruses| to automate this process. +% This causes the first chorus in each song to be automatically repeated +% after the first verse on each subsequent page of the song (unless that +% verse is already immediately followed by a chorus). +% If the first chorus is part of a set of two or more consecutive choruses, +% then the whole set of choruses is repeated. +% (A set of choruses is assumed to consist of things like pre-choruses that +% should always be repeated along with the chorus.) +% Choruses are not automatically inserted immediately after unnumbered +% verses (i.e., verses that begin with \mac{beginverse}|*|). +% Unnumbered verses are assumed to be bridges or endings that aren't +% followed by a chorus. +% +% \DescMacro{norepchoruses} +% The above covers the common cases, but some songs have more complex forms +% that demand a manual approach. +% Before a song with irregular form, say |\norepchoruses| to turn automatic +% chorus-repeating off. +% Then, at points within the song where you want a chorus to be repeated on +% the overhead slides, type a construction like, +% +% \begin{codeblock} +% \mac{ifslides} +% \mac{beginchorus} +% $\vdots$ +% \mac{endchorus} +% |\fi| +% \end{codeblock} +% +% \noindent +% and copy and paste the desired chorus into the middle. +% This inserts a repeated chorus at that point when generating slides, +% but not when generating a lyric book or chord book. +% After the song is concluded, type +% +% \begin{codeblock} +% \mac{ifslides}\mac{repchoruses}|\fi| +% \end{codeblock} +% +% \noindent +% to turn automatic chorus-repeating back on, if desired. +% +% \subsection{Chords}\label{sec:chords} +% +% \DescMacro{[} +% \DescChar{hash}{#} +% \DescChar{amp}{&} +% Between the \mac{beginverse} and \mac{endverse} lines, or between +% the \mac{beginchorus} and \mac{endchorus} lines, +% chords can be produced using the macro |\[|\meta{chordname}|]|\eat\]. +% Chords only appear in chord books; they are omitted from lyric books. +% The \meta{chordname} may consist of arbitrary text. +% To produce sharp and flat symbols, use |#| and |&| respectively. +% +% Any text that immediately follows the |\[]|\eat\] macro with no +% intervening whitespace is assumed to be the word or syllable +% that is to be sung as the chord is struck, and is therefore +% typeset directly under the chord. +% For example: +% +% \example|\[E&]peace and \[Am]joy|\produces{\[E&]peace and \[Am]joy} +% \eat\] +% +% \noindent +% If whitespace (a space or \meta{return}) immediately follows, +% then the chord name be typeset without any lyric text +% below it, indicating that the chord is to be struck between +% any surrounding words. +% For example: +% +% \example|\[E&]peace and \[Am] joy|\produces{\[E&]peace and \[Am] joy} +% \eat\] +% +% If the lyric text that immediately follows the chord contains +% another chord, and if the width of the chord name exceeds the +% width of the lyric text, then hyphenation is added automatically. +% For example: +% +% \example|\[F#sus4]e\[A]ternal|\produces{\[F#sus4]e\[A]ternal} +% \eat\] +% +% Sequences of chords that sit above a single word can be written +% back-to-back with no intervening space, or as a single chord: +% +% \example|\[A]\[B]\[Em]joy|\produces{\[A]\[B]\[Em]joy} +% \example|\[A B Em]joy|\produces{\[A B Em]joy} +% \eat\] +% +% \noindent +% The only difference between the two examples above is that the chords +% in the first example can later be replayed separately (see +% \S\ref{sec:replay}) whereas the chords in the second example can only be +% replayed as a group. +% +% You can explicitly dictate how much of the text following a +% chord macro is to appear under the chord name by using braces. +% To exclude text that would normally be drawn under the chord, +% use a pair of braces that includes the chord macro. +% For example: +% +% \example|{\[G A]e}ternal|\produces{{\[G A]e}ternal} +% \eat\] +% +% \noindent +% (Without the braces, the syllables ``ternal'' would not be +% pushed out away from the chord.) +% This might be used to indicate that the chord transition occurs +% on the first syllable rather than as the second syllable is +% sung. +% +% Contrastingly, braces that do not include the chord itself can +% be used to include text under a chord that would otherwise be +% excluded. +% For example: +% +% \example|\[Gmaj7sus4]{th' eternal}|\produces{\[Gmaj7sus4]{th' eternal}} +% \eat\] +% +% \noindent +% Without the braces, the word ``eternal'' would be pushed out away +% from the chord so that the chord would appear only over +% the partial word ``th'\thinspace''. +% +% \paragraph{Chords Without Lyrics.} +% \DescMacro{nolyrics} +% Sometimes you may want to write a line of chords with no lyrics in it at all, +% such as for an instrumental intro or solo. +% To make the chords in such a line sit on the baseline instead of raised above +% it, use the |\nolyrics| macro. +% For example: +% +% \example|{\nolyrics Intro: \[G] \[A] \[D]}|\produces{\nolyrics Intro: \[G] \[A] \[D]} +% \eat\] +% +% \noindent +% Note the enclosing braces that determine how long the effect should last. +% Multiple lines can be included in the braces. +% Instrumental solos should typically not appear in lyric books, so such +% lines should usually also be surrounded by \mac{ifchorded} and |\fi| +% (see \S\ref{sec:conditionals}). +% +% \paragraph{Symbols Under Chords.} +% \DescMacro{DeclareLyricChar} +% If you are typesetting songs in a language whose alphabet contains symbols +% that \LaTeX{} treats as punctuation, you can use the |\DeclareLyricChar| +% macro to instruct the \Songs{} package to treat the symbol as +% non-chord-ending, so that it is included under chords by default just +% like an alphabetic character. +% +% \begin{codeblock} +% |\DeclareLyricChar{|\meta{token}|}| +% \end{codeblock} +% +% \noindent +% Here, \meta{token} must be a single \TeX{} macro control sequence, +% active character, letter (something \TeX{} assigns catcode 11), or +% punctuation symbol (something \TeX{} assigns catcode 12). +% For example, by default, +% +% \example|\[Fmaj7]s\dag range|\produces{\[Fmaj7]s\dag range} +% \eat\] +% +% \noindent +% because |\dag| is not recognized as an alphabetic symbol; +% but if you first type, +% +% \begin{codeblock} +% |\DeclareLyricChar{\dag}| +% \end{codeblock} +% +% \noindent +% then instead you will get: +% +% \DeclareLyricChar{\dag} +% \example|\[Fmaj7]s\dag range|\produces{\[Fmaj7]s\dag range} +% \eat\] +% +% \noindent +% \DescMacro{DeclareNonLyric} +% Likewise, you can type +% +% \begin{codeblock} +% |\DeclareNonLyric{|\meta{token}|}| +% \end{codeblock} +% +% \noindent +% to reverse the above effect and force a token to be lyric-ending. +% Such tokens are pushed out away from long chord names so that they +% never fall under a chord, and hyphenation is added to the resulting gap. +% +% \DescMacro{DeclareNoHyphen} +% To declare a token to be lyric-ending but without the added hyphenation, +% use |\DeclareNoHyphen{|\meta{token}|}| instead. +% Such tokens are pushed out away from long chord names so that they never +% fall under the chord, but hyphenation is not added to the resulting gap. +% +% \paragraph{Extending Chords Over Adjacent Words.} +% \DescMacro{MultiwordChords} +% The |\MultiwordChords| macro forces multiple words to be squeezed under one +% chord by default. +% Normally a long chord atop a short lyric pushes subsequent +% lyrics away to make room for the chord: +% +% \example|\[Gmaj7sus4]my life|\produces{\[Gmaj7sus4]my life} +% \eat\] +% +% \noindent +% But if you first type |\MultiwordChords|, then instead you get the more +% compact: +% +% \begingroup\MultiwordChords +% \example|\[Gmaj7sus4]my life|\produces{\[Gmaj7sus4]my life} +% \eat\] +% \endgroup +% +% \noindent +% Authors should exercise caution when using |\MultiwordChords| because +% including many words under a single chord can often produce output that +% is ambiguous or misleading to musicians. +% For example, +% +% \begingroup\MultiwordChords +% \example|\[F G Am]me free|\produces{\[F G Am]me free}\par +% \eat\] +% \endgroup +% +% \noindent +% This might be misleading to musicians if all three chords are intended +% to be played while singing the word ``me.'' +% Liberal use of braces is therefore required to make |\MultiwordChords| +% produce good results, which is why it isn't the default. +% +% \paragraph{Accidentals Outside Chords.} +% \DescMacro{shrp} +% \DescMacro{flt} +% Sharp and flat symbols can be produced with |#| and |&| when they appear +% in chord macros, but if you wish to produce those symbols in +% other parts of the document, you must use the |\shrp| and |\flt| macros. +% For example, to define a macro that produces a \chord{C\shrp} chord, use: +% +% \begin{codeblock} +% |\newcommand{\Csharp}{C\shrp}| +% \end{codeblock} +% +% \subsection{Replaying Chords}\label{sec:replay} +% +% \DescChar{hat}{^} +% Many songs consist of multiple verses that use the same chords. +% The \Songs{} package simplifies this common case by providing a means to +% replay the chord sequence of a previous verse without having to retype +% all the chords. +% To replay a chord from a previous verse, type a hat symbol (|^|) anywhere +% you would otherwise use a chord macro (|\[]|\eat\]). +% For example, +% +% \begin{codeblock} +% \mac{beginverse} +% |\[G]This is the \[C]first \[G]verse.|\eat\] +% \mac{endverse} +% \mac{beginverse} +% |The ^second verse ^ has the same ^chords.| +% \mac{endverse} +% \end{codeblock} +% +% \noindent produces +% +% \begin{chorded}\memorize +% \[G]This is the \[C]first \[G]verse.\eat\] +% \end{chorded} +% \begin{chorded} +% The ^second verse ^ has the same ^chords. +% \end{chorded} +% +% Normal chords can appear amidst replayed chords without disrupting the +% sequence of chords being replayed. +% Thus, a third verse could say, +% +% \begin{codeblock} +% \mac{beginverse} +% |The ^third verse ^has a \[Cm]new ^chord.|\eat\] +% \mac{endverse} +% \end{codeblock} +% +% \noindent to produce +% +% \begin{chorded} +% The ^third verse ^has a \[Cm]new ^chord.\eat\] +% \end{chorded} +% +% Replaying can be used in combination with automatic transposition to produce +% modulated verses. +% See \S\ref{sec:transpose} for an example. +% +% \DescMacro{memorize} +% By default, chords are replayed from the current song's first verse, but +% you can replay the chords of a different verse or chorus by saying +% |\memorize| at the beginning of any verse or chorus whose chords you want +% to later replay. +% Subsequent verses or choruses that use \refchar{hat} replay chords +% from the most recently memorized verse or chorus. +% +% \paragraph{Selective Memorization.} +% It is also possible to inject unmemorized chords into a memorized verse +% so that they are not later replayed. +% To suppress memorization of a chord, begin the chord's name with a hat +% symbol. +% For example, +% +% \begin{codeblock} +% \mac{beginverse}\mac{memorize} +% |The \[G]third \[C]chord will \[^Cm]not be re\[G]played.|\eat\] +% \mac{endverse} +% \mac{beginverse} +% |When ^replaying, the ^unmemorized chord is ^skipped.| +% \mac{endverse} +% \end{codeblock} +% +% \noindent produces +% +% \begin{chorded}\memorize +% The \[G]third \[C]chord will \[^Cm]not be re\[G]played.\eat\] +% \vskip5pt% +% When ^replaying, the ^unmemorized chord is ^skipped. +% \end{chorded} +% +% \noindent +% This is useful when the first verse of a song has something unique, +% like an intro that won't be repeated in subsequent verses, but has +% other chords that you wish to replay. +% +% \paragraph{Memorizing Multiple Chord Sequences.} +% By default, the \Songs{} package only memorizes one sequence of chords +% at a time and \refchar{hat} replays chords from that most recently +% memorized sequence. +% However, you can memorize and replay multiple independent sequences +% using the macros described in the following paragraphs. +% +% \DescMacro{newchords} +% Memorized or replayed chord sequences are stored in chord-replay registers. +% To declare a new chord-replay register, type +% +% \begin{codeblock} +% |\newchords{|\meta{regname}|}| +% \end{codeblock} +% +% \noindent +% where \meta{regname} is any unique alphabetic name. +% +% Once you've declared a register, you can memorize into that register +% by providing the \meta{regname} as an optional argument to +% \mac{memorize}: +% +% \begin{codeblock} +% \mac{memorize}|[|\meta{regname}|]| +% \end{codeblock} +% +% \noindent +% Memorizing into a non-empty register replaces the contents of that +% register with the new chord sequence. +% +% \DescMacro{replay} +% To replay chord from a particular register, type +% +% \begin{codeblock} +% |\replay[|\meta{regname}|]| +% \end{codeblock} +% +% \noindent +% Subsequent uses of \refchar{hat} reproduce chords from the sequence +% stored in register \meta{regname}. +% +% Register contents are global, so you can memorize a chord sequence from one +% song and replay it in others. +% You can also use |\replay| multiple times in the same verse or chorus to +% replay a sequence more than once. +% +% \subsection{Line and Column Breaks} +% +% \paragraph{Line Breaking.} +% \DescMacro{brk} +% To cause a long line of lyrics to be broken in a particular place, put the +% |\brk| macro at that point in the line. +% This does not affect lines short enough to fit without breaking. +% For example, +% +% \begin{codeblock} +% |\beginverse| +% {\tt\frenchspacing This is a |\brk| short line. +% But this is a particularly long line of lyrics |\brk| that will need to be wrapped. +% } |\endverse| +% \end{codeblock} +% +% \noindent produces +% +% \begin{lyrics} +% This is a \brk short line. +% But this is a particularly long line of lyrics \brk that will need to be wrapped. +% \end{lyrics} +% +% \paragraph{Column Breaks Within Songs.} +% To suggest a column break within a verse or chorus too long to fit in a +% single column, use |\brk| on a line by itself. +% If there are no |\brk| lines in a long verse, it is broken +% somewhere that a line does not wrap. +% (A wrapped line is never divided by a column break.) +% If there are no |\brk| lines in a long chorus, it overflows the column, +% yielding an overfull vbox warning. +% +% \paragraph{Column Breaks Between Songs.} +% \DescMacro{nextcol} +% \DescMacro{sclearpage} +% \DescMacro{scleardpage} +% To force a column break between songs, use |\nextcol|, |\brk|, |\sclearpage|, +% or |\scleardpage| between songs. +% The |\nextcol| macro ends the column by leaving blank space at the bottom. +% The |\brk| macro ends the current column in lyric books by stretching +% the preceeding text so that the column ends flush with the bottom +% of the page. +% (In non-lyric books |\brk| is identical to |\nextcol|.) +% The |\sclearpage| macro is like |\nextcol| except that it shifts to the next +% blank page if the current page is nonempty. +% The |\scleardpage| macro is like |\sclearpage| except that it shifts to the +% next blank even-numbered page in two-sided documents. +% Column breaks usually need to be in different places in different book types. +% To achieve this, use a conditional block from \S\ref{sec:conditionals}. +% For example, +% +% \begin{codeblock} +% \mac{ifchorded}|\else|\mac{ifslides}|\else\brk\fi\fi| +% \end{codeblock} +% +% \noindent +% forces a column break only in lyric books but does not affect chord books +% or books of overhead slides. +% +% When a partial list of songs is being extracted with \mac{includeonlysongs}, +% |\brk|, |\nextcol|, |\clearpage|, and |\cleardpage| macros between songs +% must be followed by a star to have any effect. +% To force a column-break at a specific point in a partial book, add the +% word |nextcol|, |brk|, |clearpage|, or |cleardpage| at the corresponding +% point in the argument to \mac{includeonlysongs}. +% +% \subsection{Echoes and Repeats} +% +% \paragraph{Echo Parts.} +% \DescMacro{echo} +% To typeset an echo part, use |\echo{|\meta{lyrics and chords}|}|. +% Echo parts are parenthesized and italicized. +% For example, +% +% \example|Alle\[G]luia! \echo{Alle\[A]luia!}|\produces{Alle\[G]luia! \echo{Alle\[A]luia!}} +% \eat\] +% +% \paragraph{Repeated Lines.} +% \DescMacro{rep} +% To indicate that a line should be sung multiple times by all singers, put +% |\rep{|\meta{n}|}| at the end of the line. +% For example, +% +% \example|Alleluia! \rep{4}|\produces{Alleluia! \rep{4}} +% +% \DescMacro{lrep} +% \DescMacro{rrep} +% To indicate exactly where repeated parts begin and end, use |\lrep| and +% |\rrep| to create begin- and end-repeat signs. +% For example, +% +% \example|\lrep \[G]Alleluia!\rrep \rep{4}|\produces{\lrep \[G]Alleluia!\rrep \rep{4}} +% \eat\] +% +% \subsection{Measure Bars}\label{sec:measures} +% +% \DescMacro{measurebar} +% \DescChar{pipe}{|} +% Measure bars can be added to chord books in order to help musicians +% keep time when playing unfamiliar songs. +% To insert a measure bar, type either |\measurebar| or type the +% vertical pipe symbol (``\verb@|@''). +% For example, +% +% \example\verb@Alle|\[G]luia@\produces{Alle\meter{}{}\measurebar\[G]luia} +% \eat\] +% +% \noindent +% In order for measure bars to be displayed, the \env{showmeasures} +% option must be enabled. +% Measure bars are only displayed by default in chord books. +% +% \DescMacro{meter} +% The first measure bar in a song has meter numbers placed above +% it to indicate the time signature of the piece. +% By default, these numbers are 4/4, denoting four quarter notes +% per measure. +% To change the default, type |\meter{|\meta{n}|}{|\meta{d}|}| +% somewhere after the \mac{beginsong} line of the song but before the +% first measure bar, to declare a time signature of \meta{n} \meta{d}th +% notes per measure. +% +% \DescMacro{mbar} +% You can also change meters mid-song either by using |\meter| in the +% middle of the song or by typing |\mbar{|\meta{n}|}{|\meta{d}|}| +% to produce a measure bar with a time signature of \meta{n}/\meta{d}. +% For example, +% +% \begin{codeblock} +% |\meter{6}{8}| +% |\beginverse| +% \verb@|Sing to the |heavens, ye \mbar{4}{4}saints of |old!@ +% |\endverse| +% \end{codeblock} +% +% \noindent produces +% +% \begin{chorded} +% \meter{6}{8}% +% \measurebar Sing to the \measurebar heavens, ye \mbar{4}{4}saints of \measurebar old! +% \end{chorded} +% +% \subsection{Textual Notes}\label{sec:notes} +% +% \DescMacro{textnote} +% \DescMacro{musicnote} +% Aside from verses and choruses, songs can also contain textual notes +% that provide instructions to singers and musicians. +% To create a textual note that is displayed in both lyric books +% and chord books, use: +% +% \begin{codeblock} +% |\textnote{|\meta{text}|}| +% \end{codeblock} +% +% \noindent +% To create a textual note that is displayed only in chord books, use: +% +% \begin{codeblock} +% |\musicnote{|\meta{text}|}| +% \end{codeblock} +% +% \noindent +% Both of these create a shaded box containing \meta{text}. +% For example, +% +% \begin{codeblock} +% |\textnote{Sing as a two-part round.}| +% \end{codeblock} +% +% \noindent produces +% +% \begin{lyrics} +% \textnote{Sing as a two-part round.} +% \end{lyrics} +% +% \noindent +% Textual notes can be placed anywhere within a song, either within +% verses and choruses or between them. +% +% \paragraph{Guitar Capos.} +% \DescMacro{capo} +% One special kind of textual note suggests to guitarists a fret on which +% they should put their capos. +% Macro |\capo{|\meta{n}|}| should be used for this purpose. +% It normally has the same effect as \mac{musicnote}|{capo |\meta{n}|}|; +% however, if the \env{transposecapos} option is active then it +% instead has the effect of \mac{transpose}|{|\meta{n}|}|. +% See \S\ref{sec:transpose} for more information on automatic chord +% transposition. +% +% \subsection{Index Entries}\label{sec:ientry} +% +% Every song automatically gets entries in the current section's title +% index(es). +% However, you can also add extra index entries for a song to any index. +% +% \paragraph{Indexing Lyrics.} +% \DescEnv{index=} +% For example, title indexes often have entries for memorable lines +% of lyrics in a song in addition to the song's title. +% You can add an index entry for the current song to the section's +% title index(es) by adding |index={|\meta{lyrics}|}| to the song's +% \mac{beginsong} line. +% For example, +% +% \begin{codeblock} +% \mac{beginsong}|{Doxology}| +% | [index={Praise God from Whom all blessings flow}]| +% \end{codeblock} +% +% \noindent +% causes the song to be indexed both as ``\textit{Doxology}'' and as +% ``Praise God from Whom all blessings flow'' in the section's title index(es). +% You can use |index=| multiple times in a \mac{beginsong} line to produce +% multiple additional index entries. +% Index entries produced with |index={|\meta{lyrics}|}| are +% typeset in an upright font instead of in italics to distinguish +% them from song titles. +% +% \paragraph{Indexing Extra Song Titles.} +% \DescEnv{ititle=} +% To add a regular index entry typeset in italics to the title +% index(es), use: +% +% \begin{codeblock} +% |ititle={|\meta{title}|}| +% \end{codeblock} +% +% \noindent +% in the \mac{beginsong} line instead. +% Like \env{index=} keyvals, |ititle=| can be used multiple times to produce +% multiple additional index entries. +% +% \DescMacro{indexentry} +% \DescMacro{indextitleentry} +% You can also create index entries by saying +% |\indexentry[|\meta{indexes}|]{|\meta{lyrics}|}| (which creates an +% entry like \env{index=}) or +% |\indextitleentry[|\meta{indexes}|]{|\meta{title}|}| (which +% creates an entry like \env{ititle=}). +% These two macros can be used anywhere between the song's \mac{beginsong} +% and \mac{endsong} lines, and can be used multiple times to produce +% multiple entries. +% If specified, \meta{indexes} is a comma-separated list of the identifiers +% of indexes to which the entry should be added. +% Otherwise the new entry is added to all of the title indexes for the current +% \env{songs} environment. +% +% \subsection{Chords in Ligatures} +% +% This subsection covers an advanced topic and can probably be +% skipped by those creating song books for non-professional use. +% +% The \mac{[\eat]} macro is the normal means by which chords should be inserted +% into a song; however, a special case occurs when a chord falls within a +% ligature. +% Ligatures are combinations of letters or symbols that \TeX{} normally +% typesets as a single font character so as to produce cleaner-looking +% output. +% The only ligatures in English are: ff, fi, fl, ffi, and ffl. +% Other languages have additional ligatures like \ae{} and \oe. +% Notice that in each of these cases, the letters are ``squished'' +% together to form a single composite symbol. +% +% \DescMacro{ch} +% When a chord macro falls inside a ligature, \LaTeX{} fails to compact +% the ligature into a single font character even in non-chorded versions of +% the book. +% To avoid this minor typographical error, use the |\ch| macro to typeset +% the chord: +% +% \begin{codeblock} +% |\ch{|\meta{chord}|}{|\meta{pre}|}{|\meta{post}|}{|\meta{full}|}| +% \end{codeblock} +% +% \noindent +% where \meta{chord} is the chord text, \meta{pre} is the text to +% appear before the hyphen if the ligature is broken by auto-hyphenation, +% \meta{post} is the text to appear after the hyphen if the ligature +% is broken by auto-hyphenation, and \meta{full} is the full ligature +% if it is not broken by hyphenation. +% For example, to correctly typeset |\[Gsus4]dif\[G]ficult|\eat\], +% in which the \chord{G} chord falls in the middle of the ``ffi'' +% ligature, one should use: +% +% \example|di\ch{G}{f}{fi}{ffi}cult|\produces{di\ch{G}{f}{fi}{ffi}cult} +% +% \noindent +% This causes the ``ffi'' ligature to appear intact yet still correctly +% places the \chord{G} chord over the second f. +% To use the |\ch| macro with a replayed chord name (see \S\ref{sec:replay}), +% use |^| as the \meta{chord}. +% +% \DescMacro{mch} +% The |\mch| macro is exactly like the \mac{ch} macro except that it +% also places a measure bar into the ligature along with the chord. +% For example, +% +% \example|di\mch{G}{f}{fi}{ffi}cult|\produces{di\mch{G}{f}{fi}{ffi}cult} +% +% \noindent +% places both a measure bar and a \chord{G} chord after the first ``f'' +% in ``difficult'', yet correctly produces an unbroken ``ffi'' ligature +% in copies of the book in which measure bars are not displayed. +% +% In the unusual case that a meter change is required within a +% ligature, this can be achieved with a construction like: +% +% \example|\meter{6}{8}di\mch{G}{f}{fi}{ffi}cult|\produces{\meter{6}{8}di\mch{G}{f}{fi}{ffi}cult} +% +% \noindent +% The \mac{meter} macro sets the new time signature, which appears +% above the next measure bar---in this case the measure bar +% produced by the |\mch| macro. +% +% Chords and measure bars produced with \refchar{hat} or +% \refchar{pipe} are safe to use in ligatures. +% Thus, |dif|\refchar{pipe}\refchar{hat}|ficult| requires +% no special treatment; it leaves the ``ffi'' ligature intact when measure +% bars are not being displayed. +% +% \section{Between Songs}\label{sec:between} +% +% Never put any material directly into the top level of a \env{songs} +% environment. +% Doing so will disrupt the page-builder, usually producing strange page +% breaks and blank pages. +% To safely put material between songs, use one of the environments +% described in this section. +% +% \subsection{Intersong Displays}\label{sec:intersong} +% +% \DescEnv{intersong} +% To put column-width material between the songs in a \env{songs} environment, +% use an |intersong| environment: +% +% \begin{codeblock} +% |\begin{intersong}| +% $\vdots$ +% |\end{intersong}| +% \end{codeblock} +% +% \noindent +% Material contributed in an |intersong| environment is subject to the same +% column-breaking rules as songs (see \S\ref{sec:layout}), but all other +% formatting is up to you. +% By default, \LaTeX{} inserts interline glue below the last line of an +% |intersong| environment. +% To suppress this, end the |intersong| content with |\par\nointerlineskip|. +% +% \DescEnv{intersong*} +% To instead put page-width material above a song, use an |intersong*| +% environment: +% +% \begin{codeblock} +% |\begin{intersong*}| +% $\vdots$ +% |\end{intersong*}| +% \end{codeblock} +% +% \noindent +% This starts a new page if the current page already has column-width +% material in it. +% +% \DescEnv{songgroup} +% By default, all intersong displays are omitted when generating a partial +% book with \mac{includeonlysongs}. +% You can force them to be included whenever a particular song is included +% by using a |songgroup| environment: +% +% \begin{codeblock} +% |\begin{songgroup}| +% $\vdots$ +% |\end{songgroup}| +% \end{codeblock} +% +% \noindent +% Each |songgroup| environment may include any number of \env{intersong}, +% \env{intersong*}, or scripture quotations (see \S\ref{sec:scripture}), +% but must include exactly one song. +% When using \mac{includeonlysongs}, the entire group is included in the +% book if the enclosed song is included; otherwise the entire group is +% omitted. +% +% \subsection{Scripture Quotations}\label{sec:scripture} +% +% \paragraph{Starting a Scripture Quotation.} +% \DescMacro{beginscripture} +% \DescMacro{endscripture} +% A special form of intersong block typesets a scripture quotation. +% Scripture quotations begin and end with +% +% \begin{codeblock} +% |\beginscripture{|\meta{ref}|}| +% $\vdots$ +% |\endscripture| +% \end{codeblock} +% +% \noindent +% where \meta{ref} is a scripture reference that is +% typeset at the end of the quotation. +% The \meta{ref} argument should conform to the same syntax +% rules as for the \meta{ref} arguments passed to \mac{beginsong} +% macros (see \S\ref{sec:songs}). +% +% The text of the scripture quotation between the |\beginscripture| and +% |\endscripture| lines are parsed in normal paragraph mode. +% For example: +% +% \begin{codeblock} +% |\beginscripture{James 5:13}| +% {\tt\frenchspacing% +% Is any one of you in trouble? He should pray. Is anyone happy? Let him sing songs of praise. +% } |\endscripture| +% \end{codeblock} +% +% \noindent produces +% +% \begin{sample} +% \beginscripture{James 5:13} +% Is any one of you in trouble? He should pray. Is anyone happy? Let him sing songs of praise. +% \endscripture +% \end{sample} +% +% \paragraph{Tuplets.} +% \DescMacro{Acolon} +% \DescMacro{Bcolon} +% To typeset biblical poetry the way it appears in most bibles, begin each +% line with either |\Acolon| or |\Bcolon|. +% A-colons are typeset flush with the left margin, while B-colons are +% indented. +% Any lines too long to fit are wrapped with double-width hanging indentation. +% For example, +% +% \begin{codeblock} +% |\beginscripture{Psalm 1:1}| +% {\tt\frenchspacing% +% |\Acolon| Blessed is the man +% |\Bcolon| who does not walk in the counsel of the wicked +% |\Acolon| or stand in the way of sinners +% |\Bcolon| or sit in the seat of mockers. +% } |\endscripture| +% \end{codeblock} +% +% \noindent produces +% +% \begin{sample} +% \beginscripture{Psalm 1:1} +% \Acolon Blessed is the man +% \Bcolon who does not walk in the counsel of the wicked +% \Acolon or stand in the way of sinners +% \Bcolon or sit in the seat of mockers. +% \endscripture +% \end{sample} +% +% \paragraph{Stanzas.} +% \DescMacro{strophe} +% Biblical poetry is often grouped into stanzas or ``strophes'', +% each of which is separated from the next by a small vertical +% space. +% You can create that vertical space by typing |\strophe|. +% For example, +% +% \begin{codeblock} +% |\beginscripture{Psalm 88:2-3}| +% {\tt\frenchspacing% +% |\Acolon| May my prayer come before you; +% |\Bcolon| turn your ear to my cry. +% |\strophe| +% |\Acolon| For my soul is full of trouble +% |\Bcolon| and my life draws near the grave. +% } |\endscripture| +% \end{codeblock} +% +% \noindent produces +% +% \begin{sample} +% \beginscripture{Psalm 88:2-3} +% \Acolon May my prayer come before you;\par +% \Bcolon turn your ear to my cry.\par +% \strophe +% \Acolon For my soul is full of trouble\par +% \Bcolon and my life draws near the grave. +% \endscripture +% \end{sample} +% +% \paragraph{Indented Blocks.} +% \DescMacro{scripindent} +% \DescMacro{scripoutdent} +% Some bible passages, such as those that mix prose and poetry, contain +% indented blocks of text. +% You can increase the indentation level within a scripture quotation +% by using |\scripindent| and decrease it by using |\scripoutdent|. +% For example, +% +% \begin{codeblock} +% |\beginscripture{Hebrews 10:17-18}| +% {\tt\frenchspacing% +% Then he adds: +% |\scripindent| +% |\Acolon ``|Their sins and lawless acts +% |\Bcolon| I will remember no more.|''| +% |\scripoutdent| +% And where these have been forgiven, there is no longer any sacrifice for sin. +% } |\endscripture| +% \end{codeblock} +% +% \noindent produces +% +% \begin{sample} +% \beginscripture{Hebrews 10:17-18} +% Then he adds:\par +% \scripindent +% \Acolon ``Their sins and lawless acts\par +% \Bcolon I will remember no more.''\par +% \scripoutdent +% And where these have been forgiven, there is no longer any sacrifice for sin. +% \endscripture +% \end{sample} +% +% \section{Guitar Tablatures}\label{sec:tablatures} +% +% \DescMacro{gtab} +% Guitar tablature diagrams can be created by using the construct +% +% \begin{codeblock} +% |\gtab{|\meta{chord}|}{|\meta{fret}|:|\meta{strings}|:|\meta{fingering}|}| +% \end{codeblock} +% +% \noindent +% where the \meta{fret} and \meta{fingering} parts are both optional +% (and you may omit any colon that borders an omitted argument). +% +% \meta{chord} is a chord name to be placed above the diagram. +% +% \meta{fret} is an optional digit (any number from 2 to 9) placed to the +% left of the diagram. +% +% \meta{strings} should be a series of symbols, one for each string +% of the guitar from lowest pitch to highest. +% Each symbol should be one of: +% |X| if that string is not to be played, +% |0| (zero or the letter O) if that string is to be played open, or +% one of |1| through |9| if that string is to be played on the given +% numbered fret. +% +% \meta{fingering} is an optional series of digits, one for each +% string of the guitar from lowest pitch to highest. +% Each digit should be one of: +% |0| if no fingering information is to be displayed for that string (e.g., if +% the string is not being played or is being played open), or +% one of |1| through |4| to indicate that the given numbered finger is to be +% used to hold down that string. +% +% Here are some examples to illustrate: +% +% \example|\gtab{A}{X02220:001230}|\produces{\vcenterbox{\gtab{A}{{\hphantom{4}}:X02220:001230}}} +% \example|\gtab{C#sus4}{4:XX3341}|\produces{\vcenterbox{\gtab{C\shrp sus4}{4:XX3341}}} +% \example|\gtab{B&}{X13331}|\produces{\vcenterbox{\gtab{B\flt}{{\hphantom{4}}:X13331:}}} +% +% \DescMacro{minfrets} +% By default, tablature diagrams always consist of at least 4 fret rows +% (more if the \meta{strings} argument contains a number larger than 4). +% To change the minimum number of fret rows, change the value of |\minfrets|. +% For example, typing +% +% \begin{codeblock} +% |\minfrets=1| +% \end{codeblock} +% +% \noindent +% causes tablature diagrams to have only as many rows are required to +% accommodate the largest digit appearing in the \meta{strings} argument. +% +% \section{Automatic Transposition}\label{sec:transpose} +% +% \DescMacro{transpose} +% You can automatically transpose some or all of the chords in a song up by +% \meta{n} half-steps by adding the line +% +% \begin{codeblock} +% |\transpose{|\meta{n}|}| +% \end{codeblock} +% +% \noindent +% somewhere between the song's \mac{beginsong} line and the first chord to +% be transposed. +% For example, if a song's first chord is |\[D]|\eat\], and the line +% |\transpose{2}| appears before it, then the chord appears as an +% \chord{E} in the resulting document. +% Specifying a negative number for \meta{n} transposes subsequent chords +% down instead of up. +% +% The |\transpose| macro affects all chords appearing after it until the +% \mac{endsong} line. +% If two |\transpose| macros appear in the same song, their effects are +% cumulative. +% +% When the \env{transposecapos} option is active, the \mac{capo} +% macro acts like |\transpose|. +% See \S\ref{sec:notes} for more information. +% +% \paragraph{Enharmonics.} +% \DescMacro{preferflats} +% \DescMacro{prefersharps} +% When using \mac{transpose} to automatically transpose the chords of a song, +% the \Songs{} package code chooses between enharmonically equivalent +% names for ``black key'' notes based on the first chord of the song. +% For example, if |\transpose{1}| is used, and if the first chord of the +% song is an \chord{E}, then all \chord{A} chords that appear in +% the song are transcribed as \chord{B\flt} chords rather than +% \chord{A\shrp} chords, since the key of \chord{F}-major (\chord{E} +% transposed up by one half-step) has a flatted key signature. +% Usually this guess produces correct results, but if not, you can use +% either |\preferflats| or |\prefersharps| after the \mac{transpose} line +% to force all transcription to use flatted names or sharped names +% respectively, when resolving enharmonic equivalents. +% +% \paragraph{Modulated Verses.} +% Automatic transposition can be used in conjunction with chord-replaying +% (see \S\ref{sec:chords}) to produce modulated verses. +% For example, +% +% \begin{codeblock} +% \mac{beginverse}\mac{memorize} +% |\[F#]This is a \[B/F#]memorized \[F#]verse. \[E&7]|\eat\] +% \mac{endverse} +% \mac{transpose}|{2}| +% \mac{beginverse} +% |^This verse is ^modulated up two ^half-steps.| +% \mac{endverse} +% \end{codeblock} +% +% \noindent produces +% +% \begin{chorded}\memorize +% \[F#]This is a \[B/F#]memorized \[F#]verse. \[E&7]\eat\] +% \vskip5pt\replay\transpose{2}% +% ^This verse is ^modulated up two ^half-steps. +% \transpose{-2}% +% \end{chorded} +% +% \paragraph{Both Keys.} +% \DescMacro{trchordformat} +% By default, when chords are automatically transposed using \mac{transpose}, +% only the transposed chords are printed. +% However, in some cases you may wish to print the old chords and the +% transposed chords together so that musicians playing transposing and +% non-transposing instruments can play from the same piece of music. +% This can be achieved by redefining the |\trchordformat| macro, which +% receives two arguments---the original chord name and the transposed chord +% name, respectively. +% For example, to print the old chord above the new chord above each lyric, +% define +% +% \begin{codeblock} +% |\renewcommand{\trchordformat}[2]{\vbox{\hbox{#1}\hbox{#2}}}| +% \end{codeblock} +% +% \paragraph{Changing Note Names.} +% \DescMacro{solfedge} +% \DescMacro{alphascale} +% In many countries it is common to use the solfedge names for the notes of +% the scale (\chord{LA, SI, DO, RE, MI, FA, SOL\/}) instead of the +% alphabetic names (\chord{A, B, C, D, E, F, G\/}). +% By default, the transposition logic only understands alphabetic names, but +% you can tell it to look for solfedge names by typing |\solfedge|. +% To return to alphabetic names, type |\alphascale|. +% +% \DescMacro{notenames} +% You can use other note names as well. +% To define your own note names, type +% +% \begin{codeblock} +% |\notenames{|\meta{nameA}|}{|\meta{nameB}|}|$\ldots$|{|\meta{nameG}|}| +% \end{codeblock} +% +% \noindent +% where each of \meta{nameA} through \meta{nameG} must consist entirely of +% a sequence of one or more \emph{uppercase} letters. +% For example, some solfedge musicians use \chord{TI} instead of \chord{SI} +% for the second note of the scale. +% To automatically transpose such music, use: +% +% \begin{codeblock} +% |\notenames{LA}{TI}{DO}{RE}{MI}{FA}{SOL}| +% \end{codeblock} +% +% \DescMacro{notenamesin} +% \DescMacro{notenamesout} +% The \Songs{} package can also automatically convert one set of note names +% to another. +% For example, suppose you have a large song book in which chords have been +% typed using alphabetic note names, but you wish to produce a book that +% uses the equivalent solfedge names. +% You could achieve this by using the |\notenamesin| macro to tell the +% \Songs{} package which note names you typed in the input file, and then +% using |\notenamesout| to tell the \Songs{} package how you want it to +% typeset each note name in the output file. +% The final code looks like this: +% +% \begin{codeblock} +% |\notenamesin{A}{B}{C}{D}{E}{F}{G}| +% |\notenamesout{LA}{SI}{DO}{RE}{MI}{FA}{SOL}| +% \end{codeblock} +% +% \noindent +% The syntaxes of |\notenamesin| and |\notenamesout| are identical to that +% of \mac{notenames} (see above), except that the arguments of |\notenamesout| +% can consist of any \LaTeX{} code that is legal in horizontal mode, not just +% uppercase letters. +% +% To stop converting between note names, use \mac{alphascale}, \mac{solfedge}, +% or \mac{notenames} to reset all note names back to identical input and +% output scales. +% +% \paragraph{Transposing Chords In Macros.} +% \DescMacro{transposehere} +% The automatic transposition logic won't find chord names that are hidden +% inside macro bodies. +% For example, if you abbreviate a chord by typing, +% +% \begin{codeblock} +% |\newcommand{\mychord}{F|\mac{shrp}| sus4/C|\mac{shrp}|}| +% \mac{transpose}|{4}| +% |\[\mychord]|\eat\] +% \end{codeblock} +% +% \noindent +% then the \mac{transpose} macro fails to transpose it; the +% resulting chord is still an \chord{F\shrp sus4/C\shrp} chord. +% To fix the problem, you can use |\transposehere| in your macros to +% explicitly invoke the transposition logic on chord names embedded in +% macro bodies. +% The above example could be corrected by instead defining: +% +% \begin{codeblock} +% |\newcommand{\mychord}{\transposehere{F|\mac{shrp}| sus4/C|\mac{shrp}|}}| +% \end{codeblock} +% +% \DescMacro{notrans} +% Transposition can be suppressed within material that would otherwise be +% transposed by using the |\notrans| macro. +% For example, writing +% +% \begin{codeblock} +% \mac{transposehere}|{G = \notrans{G}}| +% \end{codeblock} +% +% \noindent +% would typeset a transposed \chord{G} followed by a non-transposed +% \chord{G} chord. +% This does not suppress note name conversion (see \mac{notenames}). +% To suppress both transposition and note name conversion, just use +% braces (e.g., |{G}| instead of |\notrans{G}|). +% +% \paragraph{Transposing Guitar Tablatures.} +% \DescMacro{gtabtrans} +% The songs package cannot automatically transpose tablature diagrams +% (see \S\ref{sec:tablatures}). +% Therefore, when automatic transposition is taking place, only the chord +% names of \mac{gtab} macros are displayed (and transposed); the diagrams +% are omitted. +% To change this default, redefine the |\gtabtrans| macro, whose two +% arguments are the two arguments to \mac{gtab}. +% For example, to display original tablatures without transposing them even +% when transposition has been turned on, write +% +% \begin{codeblock} +% |\renewcommand{\gtabtrans}[2]{|\mac{gtab}|{|\mac{notrans}|{#1}}{#2}}| +% \end{codeblock} +% +% \noindent +% To transpose the chord name but not the diagram under it, replace +% \mac{notrans}|{#1}| with simply |#1| in the above. +% To restore the default behavior, write +% +% \begin{codeblock} +% |\renewcommand{\gtabtrans}[2]{|\mac{transposehere}|{#1}}| +% \end{codeblock} +% +% \section{Customizing the Book} +% +% \subsection{Song and Verse Numbering}\label{sec:numbering} +% +% \paragraph{Song Numbering.} +% \DescEnv{songnum} +% The |songnum| counter defines the next song's number. +% It is set to 1 at the beginning of a \env{songs} environment and is +% increased by 1 after each \mac{endsong}. +% It can be redefined anywhere except within a song. +% For example, +% +% \begin{codeblock} +% |\setcounter{songnum}{3}| +% \end{codeblock} +% +% \noindent sets the next song's number to be 3. +% +% \DescMacro{thesongnum} +% You can change the song numbering style for a song section by redefining +% |\thesongnum|. +% For example, to cause songs to be numbered A1, A2, etc., in the current +% song section, type +% +% \begin{codeblock} +% |\renewcommand{\thesongnum}{A\arabic{songnum}}| +% \end{codeblock} +% +% \noindent +% The expansion of |\thesongnum| must always produce plain text with no +% font formatting or unexpandable macro tokens, since its text is +% exported to auxiliary index generation files where it is sorted. +% +% \DescMacro{printsongnum} +% To change the formatting of song numbers as they appear at the beginning +% of each song, redefine the |\printsongnum| macro, +% which expects the text yielded by \mac{thesongnum} as its only argument. +% For example, to typeset song numbers in italics atop each song, define +% +% \begin{codeblock} +% |\renewcommand{\printsongnum}[1]{\it\LARGE#1}| +% \end{codeblock} +% +% \DescMacro{songnumwidth} +% The |\songnumwidth| length defines the width of the shaded boxes that contain +% song numbers at the beginning of each song. +% For example, to make each such box 2 centimeters wide, you could define +% +% \begin{codeblock} +% |\setlength{\songnumwidth}{2cm}| +% \end{codeblock} +% +% \noindent +% If |\songnumwidth| is set to zero, song numbers are not shown at all. +% +% \DescMacro{nosongnumbers} +% To turn off song numbering entirely, type |\nosongnumbers|. +% This inhibits the display of the song number atop each song +% (but song numbers are still be displayed elsewhere, such as in indexes). +% The same effect can be achieved by setting \mac{songnumwidth} to zero. +% +% \paragraph{Verse Numbering.} +% \DescEnv{versenum} +% The |versenum| counter defines the next verse's number. +% It is set to 1 after each \mac{beginsong} line and is increased by 1 after +% each \mac{endverse} (except if the verse begins with \mac{beginverse}|*|). +% The |versenum| counter can be redefined anywhere within a song. +% For example, +% +% \begin{codeblock} +% |\setcounter{versenum}{3}| +% \end{codeblock} +% +% \noindent sets the next verse's number to be 3. +% +% \DescMacro{theversenum} +% You can change the verse numbering style by redefining |\theversenum|. +% For example, to cause verses to be numbered in uppercase roman numerals, +% define +% +% \begin{codeblock} +% |\renewcommand{\theversenum}{\Roman{versenum}}| +% \end{codeblock} +% +% \DescMacro{printversenum} +% To change the formatting of verse numbers as they appear at the beginning +% of each verse, redefine the |\printversenum| macro, +% which expects the

\end{codeblock} +% +% \DescMacro{versenumwidth} +% The |\versenumwidth| length defines the horizontal space reserved for verse +% numbers to the left of each verse text. +% Verse text is shifted right by this amount. +% For example, to reserve half a centimeter of space for verse numbers, define +% +% \begin{codeblock} +% |\setlength{\versenumwidth}{0.5cm}| +% \end{codeblock} +% +% Verse numbers

\DescMacro{noversenumbers} +% To turn off verse numbering entirely, use |\noversenumbers|. +% This is equivalent to saying +% +% \begin{codeblock} +% |\renewcommand{|\mac{printversenum}|}[1]{}| +% |\setlength{\versenumwidth}{0pt}| +% \end{codeblock} +% +% \DescMacro{placeversenum} +% The horizontal placement of verse numbers within the first line of each +% verse is controlled by the

of the implementation section for more +% information on this macro.} +% {For more information on this macro, recompile this documentation with +% the implementation section included.} +% +% \subsection{Song Appearance} +% +% \paragraph{Font Selection.} +% \DescMacro{lyricfont} +% By default, lyrics are typeset using the document-default font +% (|\normalfont|) and with the document-default point size (|\normalsize|). +% You can change these defaults by redefining |\lyricfont|. +% For example, to cause lyrics to be typeset in small sans serif font, +% you could define +% +% \begin{codeblock} +% |\renewcommand{\lyricfont}{\sffamily\small}| +% \end{codeblock} +% +% \DescMacro{stitlefont} +% Song titles are typeset in a sans-serif, slanted font by default +% (sans-serif, upright if producing slides). +% You can change this default by redefining |\stitlefont|. +% For example, to cause titles to be typeset in a roman font, you could +% define +% +% \begin{codeblock} +% |\renewcommand{\stitlefont}{\rmfont\Large}| +% \end{codeblock} +% +% \DescMacro{versefont} +% \DescMacro{chorusfont} +% \DescMacro{notefont} +% You can apply additional font changes to verses, choruses, and +% textual notes produced with \mac{textnote} and \mac{musicnote} by +% redefining |\versefont|, |\chorusfont|, and |\notefont|, respectively. +% For example, to typeset choruses in italics, you could define +% +% \begin{codeblock} +% |\renewcommand{\chorusfont}{\it}| +% \end{codeblock} +% +% \DescMacro{notebgcolor} +% \DescMacro{snumbgcolor} +% The colors of shaded boxes containing textual notes and song numbers +% can be changed by redefining the |\notebgcolor| and |\snumbgcolor| +% macros. +% For example: +% +% \begin{codeblock} +% |\renewcommand{\notebgcolor}{red}| +% \end{codeblock} +% +% \DescMacro{printchord} +% By default, chords are typeset in sans serif oblique (slanted) font. +% You can customize chord appearance by redefining |\printchord|, which +% accepts the chord text as its argument. +% For example, to cause chords to be printed in roman boldface font, +% you could define +% +% \begin{codeblock} +% |\renewcommand{\printchord}[1]{\rmfamily\bf#1}| +% \end{codeblock} +% +% \paragraph{Accidental Symbols.} +% \DescMacro{sharpsymbol} +% \DescMacro{flatsymbol} +% By default, sharp and flat symbols are typeset using \LaTeX's +% |\#| ($\#$) and |\flat| ($\flat$) macros. +% Users can change this by redefining |\sharpsymbol| and |\flatsymbol|. +% For example, to use |\sharp| ($\sharp$) instead of $\#$, one could +% redefine |\sharpsymbol| as follows. +% +% \begin{codeblock} +% |\renewcommand{\sharpsymbol}{\ensuremath{^\sharp}}| +% \end{codeblock} +% +% \paragraph{Verse and Chorus Titles.} +% \DescMacro{everyverse} +% \DescMacro{everychorus} +% The |\everyverse| macro is executed at the beginning of each verse, and +% |\everychorus| is executed at the beginning of each chorus. +% Thus, to begin each chorus with the word ``Chorus:'' one could type, +% +% \begin{codeblock} +% |\renewcommand{\everychorus}{|\mac{textnote}|{Chorus:}}| +% \end{codeblock} +% +% \paragraph{Spacing Options.} +% \DescMacro{versesep} +% The vertical distance between song verses and song choruses is defined by +% the skip register |\versesep|. +% For example, to put 12 points of space between each pair of verses and +% choruses, with a flexibility of plus or minus 2 points, you could define +% +% \begin{codeblock} +% |\versesep=12pt plus 2pt minus 2pt| +% \end{codeblock} +% +% \DescMacro{afterpreludeskip} +% \DescMacro{beforepostludeskip} +% The vertical distance between the song's body and its prelude and postlude +% material is controlled by skips |\afterpreludeskip| and +% |\beforepostludeskip|. +% This glue can be made stretchable for centering effects. +% For example, to cause each song body to be centered on the page with one +% song per page, you could write: +% +% \begin{codeblock} +% \mac{songcolumns}|{1}| +% \mac{spenalty}|=-10000| +% |\afterpreludeskip=2pt plus 1fil| +% |\beforepostludeskip=2pt plus 1fil| +% \end{codeblock} +% +% \DescMacro{baselineadj} +% The vertical distance between the baselines of consecutive lines of +% lyrics is computed by the \Songs{} package based on several factors +% including the lyric font size, the chord font size (if in \env{chorded} +% mode), and whether \env{slides} mode is currently active. +% You can adjust the results of this computation by redefining skip +% register |\baselineadj|. +% For example, to reduce the natural distance between baselines by 1 point +% but allow an additional 1 point of stretching when attempting to balance +% columns, you could define +% +% \begin{codeblock} +% |\baselineadj=-1pt plus 1pt minus 0pt| +% \end{codeblock} +% +% \DescMacro{clineparams} +% To change the vertical distance between chords and the lyrics below them, +% redefine the |\clineparams| macro with a definition that adjusts the +% \LaTeX{} parameters |\baselineskip|, |\lineskiplimit|, and |\lineskip|. +% For example, to cause the baselines of chords and their lyrics to be +% 12 points apart with at least 1 point of space between the bottom of the +% chord and the top of the lyric, you could write: +% +% \begin{codeblock} +% |\renewcommand{\clineparams}{| +% | \baselineskip=12pt| +% | \lineskiplimit=1pt| +% | \lineskip=1pt| +% |}| +% \end{codeblock} +% +% \DescMacro{cbarwidth} +% The width of the vertical line that appears to the left of choruses is +% controlled by the |\cbarwidth| length. +% To eliminate the line entirely (and the spacing around it), you can set +% |\cbarwidth| to |0pt|: +% +% \begin{codeblock} +% |\setlength{\cbarwidth}{0pt}| +% \end{codeblock} +% +% \DescMacro{sbarheight} +% The height of the horizontal line that appears between each pair of songs +% is controlled by the |\sbarheight| length. +% To eliminate the line entirely (and the spacing around it), you can set +% |\sbarheight| to |0pt|: +% +% \begin{codeblock} +% |\setlength{\sbarheight}{0pt}| +% \end{codeblock} +% +% \paragraph{Song Top and Bottom Material.} +% You can adjust the header and footer material that precedes and concludes +% each song by redefining |\extendprelude| and |\extendpostlude|. +% +% \DescMacro{extendprelude} +% \DescMacro{showauthors} +% \DescMacro{showrefs} +% By default, |\extendprelude| displays the song's authors and scripture +% references using the macros |\showauthors| and |\showrefs|. +% The following definition changes it to also print copyright info: +% +% \begin{codeblock} +% |\renewcommand{\extendprelude}{| +% | |\mac{showrefs}\mac{showauthors} +% | {\bfseries|\mac{songcopyright}|\par}| +% |}| +% \end{codeblock} +% +% \DescMacro{extendpostlude} +% By default, |\extendpostlude| prints the song's copyright and licensing +% information as a single paragraph using \mac{songcopyright} and +% \mac{songlicense}. +% The following definition changes it to also print the words +% ``Used with permission'' at the end of every song's footer information: +% +% \begin{codeblock} +% |\renewcommand{\extendpostlude}{| +% | |\mac{songcopyright}|\ |\mac{songlicense}|\unskip| +% | \ Used with permission.| +% |}| +% \end{codeblock} +% +% In general, any macro documented in \S\ref{sec:songinfo} can be used +% in |\extendprelude| and |\extendpostlude| to print song information, such +% as \mac{songauthors}, \mac{songrefs}, \mac{songcopyright}, and +% \mac{songlicense}. +% For convenience, the \mac{showauthors} and \mac{showrefs} macros display +% author and scripture reference information as a pre-formatted paragraph +% the way it appears in the default song header blocks. +% +% See \S\ref{sec:newkey} for how to define new \mac{beginsong} keyvals and +% use them in |\extendprelude|. +% +% \DescMacro{makeprelude} +% \DescMacro{makepostlude} +% For complete control over the appearance of the header and footer material +% that precedes and concludes each song, you can redefine the macros +% |\makeprelude| and |\makepostlude|. +% When typesetting a song, the \Songs{} package code invokes both of these +% macros once (after processing all the material between the \mac{beginsong} +% and \mac{endsong} lines), placing the results within vboxes. +% The resulting vboxes are placed atop and below the song content. +% By default, |\makeprelude| displays the song's titles, authors, and scripture +% references to the right of a shaded box containing the song's number; and +% |\makepostlude| displays the song's copyright and licensing information in +% fine print. +% +% \paragraph{Page- and Column-breaking.} +% \DescMacro{vvpenalty} +% \DescMacro{ccpenalty} +% \DescMacro{vcpenalty} +% \DescMacro{cvpenalty} +% \DescMacro{brkpenalty} +% Page-breaking and column-breaking within songs that are too large to fit +% in a single column/page is influenced by the values of several penalties. +% Penalties of value |\interlinepenalty| are inserted between consecutive +% lines of each verse and chorus; +% penalties of value |\vvpenalty|, |\ccpenalty|, |\vcpenalty|, and |\cvpenalty| +% are inserted into each song between consecutive verses, between consecutive +% choruses, after a verse followed by a chorus, and after a chorus followed by +% a verse, respectively; +% and penalties of value |\brkpenalty| are inserted wherever \mac{brk} is +% used on a line by itself. +% The higher the penalty, the less likely \TeX{} is to place a +% page- or column-break at that site. +% If any are set to $-10000$ or lower, breaks are forced there. +% By default, |\interlinepenalty| is set to 1000 and the rest are set to 200 +% so that breaks between verses and choruses are preferred over breaks within +% choruses and verses, but are not forced. +% +% \DescMacro{sepverses} +% Saying |\sepverses| sets all of the above penalties to $-10000$ except for +% |\ccpenalty| which is set to 100. +% This is useful in \env{slides} mode because it forces each verse and +% chorus to be typeset on a separate slide, except for consecutive choruses, +% which remain together when possible. +% (This default reflects an expectation that consecutive choruses typically +% consist of a pre-chorus and chorus that are always sung together.) +% +% These defaults can be changed by changing the relevant penalty register +% directly. +% For example, to force a page- or column-break between consecutive choruses, +% type +% +% \begin{codeblock} +% |\ccpenalty=-10000| +% \end{codeblock} +% +% \paragraph{Text Justification.} +% \DescMacro{versejustify} +% \DescMacro{chorusjustify} +% \DescMacro{justifyleft} +% \DescMacro{justifycenter} +% To cause verse or chorus text to be justified flush-left or centered, set +% |\versejustify| or |\chorusjustify| to |\justifyleft| or |\justifycenter|, +% respectively. +% For example, to cause choruses to be centered, one could type: +% +% \begin{codeblock} +% |\renewcommand{|\mac{chorusjustify}|}{\justifycenter}| +% \end{codeblock} +% +% \DescMacro{notejustify} +% Justification of textual notes too long to fit on a single line +% is controlled by the |\notejustify| macro. +% By default, it sets up an environment that fully justifies the note +% (i.e., all but the last line of each paragraph extends all the way from +% the left to the right margin). +% \ImplOrDesc +% {Authors interested in changing this behavior should consult +% \S\ref{sec:impparams} of the implementation section for more +% information about this macro.} +% {For more information, recompile this documentation with the +% implementation section included.} +% +% \DescMacro{placenote} +% A textual note that is shorter than a single line is placed flush-left by +% default, or is centered when in slides mode. +% This placement of textual notes is controlled by |\placenote|. +% \ImplOrDesc +% {Authors interested in changing this behavior should consult +% \S\ref{sec:impparams} of the implementation section for more +% information about this macro.} +% {For more information, recompile this documentation with the +% implementation section included.} +% +% \subsection{Scripture Appearance} +% +% \DescMacro{scripturefont} +% By default, scripture quotations are typeset in Zaph Chancery font +% with the document-default point size (|\normalsize|). +% You can change these defaults by redefining |\scripturefont|. +% For example, to cause scripture quotations to be typeset in sans serif +% italics, define: +% +% \begin{codeblock} +% |\renewcommand{\scripturefont}{\sffamily\it}| +% \end{codeblock} +% +% \DescMacro{printscrcite} +% By default, the citation at the end of a scripture quotation is +% typeset in sans serif font at the document-default point size +% (|\normalsize|). +% You can customize the appearance of the citation by redefining +% |\printscrcite|, which accepts the citation text as its argument. +% For example, to cause citations to be printed in roman italics font, define: +% +% \begin{codeblock} +% |\renewcommand{\printscrcite}[1]{\rmfamily\it#1}| +% \end{codeblock} +% +% \subsection{Conditional Blocks}\label{sec:conditionals} +% +% Conditional macros allow certain material to be included in some books but +% not others. +% For example, a musician's chord book might include extra verses with +% alternate chordings. +% +% \DescMacroGroup{if}{if...}{ifchorded,iflyric,ifslides,ifpartiallist,ifsongindexes,ifmeasures,ifrawtext,iftranscapos,ifnolyrics,ifpagepreludes,ifvnumbered} +% A

block concludes with the macro |\fi|. +% Between the |\if|\meta{type} and the |\fi| may also appear an |\else|. +% For example, in the construction +% +% \begin{codeblock} +% |\ifchorded| +% \quad\meta{A} +% |\else| +% \quad\meta{B} +% |\fi| +% \end{codeblock} +% +% \noindent +% material \meta{A} is only included if the \env{chorded} option is active, +% and material \meta{B} is only included if the \env{chorded} option is not +% active. +% +% \subsection{Page Layout}\label{sec:layout} +% +% \DescMacro{songcolumns} +% The number of columns per page can be set with |\songcolumns|. +% For example, to create 3 columns per page, write +% +% \begin{codeblock} +% |\songcolumns{3}| +% \end{codeblock} +% +% \noindent +% The number of columns should only be changed outside of \env{songs} +% environments. +% +% Setting the number of columns to zero disables the page-building algorithm +% entirely. +% This can be useful if you want to use an external package, such as +% |multicol| or \LaTeX's built-in |\twocolumn| macro, to build pages. +% For example, the following sets up an environment that is suitable for +% a lyric book that uses |\twocolumn|: +% +% \begin{codeblock} +% |\songcolumns{0}| +% |\flushbottom| +% |\twocolumn[\LARGE\centering My Songs]| +% |\begin{|\env{songs}|}{}| +% $\vdots$ +% |\end{|\env{songs}|}| +% \end{codeblock} +% +% \noindent +% When disabling the page-builder, please note the following potential +% issues: +% +% \begin{itemize} +% \item The \mac{repchoruses} feature does not work when the page-builder +% is disabled because the page-builder is responsible for inserting +% repeated choruses as new columns are formed. +% \item External page-building packages tend to allow column- and +% page-breaks within songs because they have no mechanism for moving an +% entire song to the next column or page to avoid such a break +% (see \mac{songpos} below). +% \item Indexes produced with \mac{showindex} are typeset to the width of +% the enclosing environment. +% Thus, you should be sure to reset \LaTeX{} back to one column (via +% |\onecolumn|) before executing \mac{showindex}. +% \end{itemize} +% +% \DescMacro{pagepreludes} +% Song preludes (i.e., the material atop each song, including the title) are +% typeset by default at column width. +% Writing |\pagepreludes| typesets subsequent preludes at page width atop +% fresh pages, with the rest of the song in multiple columns beneath its title. +% (To prohibit separation of songs from their preludes, it also sets +% \mac{songpos} to 0.) +% +% \DescMacro{columnsep} +% The horizontal distance between consecutive columns is controlled by +% the |\columnsep| dimension. +% For example, to separate columns by 1 centimeter of space, write +% +% \begin{codeblock} +% |\columnsep=1cm| +% \end{codeblock} +% +% \DescMacro{colbotglue} +% When \LaTeX{} ends each column it inserts glue equal to |\colbotglue|. +% In lyric books this macro is set to |0pt| so that each column ends flush with +% the bottom of the page. +% In other books that have ragged bottoms, it is set to stretchable +% glue so that columns end at whatever vertical position is convenient. +% The recommended setting for typsetting columns with ragged bottoms is: +% +% \begin{codeblock} +% |\renewcommand{\colbotglue}{0pt plus .5\textheight minus 0pt}| +% \end{codeblock} +% +% \DescMacro{lastcolglue} +% The last column in a \env{songs} environment gets |\lastcolglue| appended +% to it instead. +% By default it is infinitely stretchable so that the last column ends +% at its natural height. +% By setting it to |0pt|, you can force the last column to be flush with +% the bottom of the page: +% +% \begin{codeblock} +% |\renewcommand{\lastcolglue}{0pt}| +% \end{codeblock} +% +% \DescMacro{songpos} +% The \Songs{} package uses a song-positioning algorithm that +% moves songs to the next column or page in order to avoid column- or +% page-breaks within songs. +% The algorithm has four levels of aggressiveness, numbered from 0 to 3. +% You can change the aggressiveness level by typing +% +% \begin{codeblock} +% |\songpos{|\meta{level}|}| +% \end{codeblock} +% +% \noindent +% The default level is 3, which avoids column-breaks, page-breaks, +% and page-turns within songs whenever possible. +% (Page-turns are page-breaks after odd-numbered pages in two-sided documents, +% or after all pages in one-sided documents.) +% Level 2 avoids page-breaks and page-turns but allows column-breaks within +% songs. +% Level 1 avoids only page-turns within songs. +% Level 0 turns off the song-positioning algorithm entirely. +% This causes songs to be positioned wherever \TeX{} thinks is best +% based on penalty settings (see \mac{vvpenalty} and \mac{spenalty}). +% +% \DescMacro{spenalty} +% The value of |\spenalty| controls the undesirability of column breaks +% at song boundaries. +% Usually it should be set to a value between 0 and \mac{vvpenalty} so that +% breaks between songs are preferable to breaks between verses within a song. +% By default it is set to 100. +% When it is $-10000$ or less, breaks between songs are required, so that +% each song always begins a fresh column. +% +% \subsection{Indexes}\label{sec:idxcust} +% +% \paragraph{Index Appearance.} +% \DescMacro{indexsongsas} +% By default, the right-hand side of each index entry contains a list of +% one or more song numbers. +% To instead list page numbers, use the |\indexsongsas| macro: +% +% \begin{codeblock} +% |\indexsongsas{|\meta{id}|}{\thepage}| +% \end{codeblock} +% +% \noindent +% where \meta{id} is the same identifier used in the \mac{newindex}, +% \mac{newauthorindex}, or \mac{newscripindex} macro that created the index. +% The second argument must always be something that expands into raw text +% without any formatting, since this text gets output to auxiliary files that +% are lexographically sorted by the index-generation program. +% To go back to indexing songs by song number, use \mac{thesongnum} in place +% of |\thepage| in the above. +% +% \DescMacro{sepindexestrue} +% \DescMacro{sepindexesfalse} +% Indexes are by default typeset on separate pages, and when an index is +% sufficiently small, it is centered on the page in one column. +% To disable these defaults, write |\sepindexesfalse|. +% This causes indexes to avoid using unnecessary vertical space or +% starting unnecessary new pages. +% To re-enable the defaults, use |\sepindexestrue|. +% +% \DescMacro{idxrefsfont} +% To control the formatting of the list of references on the right-hand side +% of index entries, redefine |\idxrefsfont|. +% For example, to typeset each list in boldface, write +% +% \begin{codeblock} +% |\renewcommand{\idxrefsfont}{\bfseries}| +% \end{codeblock} +% +% \DescMacro{idxtitlefont} +% \DescMacro{idxlyricfont} +% Title indexes contain entries for song titles and also entries for notable +% lines of lyrics. +% The fonts for these entries are controlled by |\idxtitlefont| and +% |\idxlyricfont|, respectively. +% For example, to show title entries in boldface sans-serif and lyric entries +% in regular roman font, one could define: +% +% \begin{codeblock} +% |\renewcommand{\idxtitlefont}{\sffamily\bfseries}| +% |\renewcommand{\idxlyricfont}{\rmfamily\mdseries}| +% \end{codeblock} +% +% \DescMacro{idxheadfont} +% To change the font used to typeset the capital letters that start each +% alphabetic section of a large title index, redefine |\idxheadfont|. +% For example, to typeset those letters in italics instead of boldface, type +% +% \begin{codeblock} +% |\renewcommand{\idxheadfont}{\sffamily\it\LARGE}| +% \end{codeblock} +% +% \DescMacro{idxbgcolor} +% To change the background color of the shaded boxes that contain the +% capital letters that start each alphabetic sectino of a large title +% index, redefine |\idxbgcolor|. +% For example: +% +% \begin{codeblock} +% |\renewcommand{\idxbgcolor}{red}| +% \end{codeblock} +% +% \DescMacro{idxheadwidth} +% The |\idxheadwidth| length defines the width of the shaded boxes that +% begin each alphabetic block of a large title index. +% Setting it to 0pt suppresses the boxes entirely. +% For example, to set the width of those boxes to 1 centimeter, you could +% define +% +% \begin{codeblock} +% |\setlength{\idxheadwidth}{1cm}| +% \end{codeblock} +% +% \DescMacro{idxauthfont} +% The font used to typeset entries of an author index is controlled by +% |\idxauthfont|. +% For example, to typeset such entries in italics instead of boldface, type +% +% \begin{codeblock} +% |\renewcommand{\idxauthfont}{\small\it}| +% \end{codeblock} +% +% \DescMacro{idxscripfont} +% The font used to typeset entries of a scripture index is controlled by +% |\idxscripfont|. +% For example, to typeset such entries in boldface instead of italics, type +% +% \begin{codeblock} +% |\renewcommand{\idxscripfont}{\sffamily\small\bfseries}| +% \end{codeblock} +% +% \DescMacro{idxbook} +% To control the formatting of the lines that start each new book of the +% bible in a scripture index, redefine |\idxbook|, which accepts the book +% name as its single argument. +% For example, to typeset each book name in a box, one could define +% +% \begin{codeblock} +% |\renewcommand{\idxbook}[1]{\framebox{\small\bfseries#1}}| +% \end{codeblock} +% +% \DescMacro{idxcont} +% In a scripture index, when a column break separates a block of entries +% devoted to a book of the bible, the new column is titled +% ``\meta{bookname} (continued)'' by default. +% You can change this default by redefining the |\idxcont| macro, which +% receives the \meta{bookname} as its single argument. +% For example, to typeset an index in German, one might define +% +% \begin{codeblock} +% |\renewcommand{\idxcont}[1]{\small\textbf{#1} (fortgefahren)}| +% \end{codeblock} +% +% \paragraph{PDF bookmarks and links.} +% \DescMacro{songtarget} +% \DescMacro{songlink} +% Each \env{song} environment adds a PDF bookmark (if generating a PDF) +% and hyperlink target (if using the |hyperref| package) for the +% song by invoking |\songtarget| with two arguments: +% (1) a suggested PDF bookmark level, and (2) a link target name. +% Links in indexes to these targets are created by |\songlink|, which +% also gets two arguments: +% (1) the link target name (same as the second argument to \mac{songtarget}), +% and (2) the text to be linked. +% +% Redefine these macros to customize or suppress these bookmarks and targets. +% For example, to enable both bookmarks and links (the default behavior) use: +% +% \begin{codeblock} +% |\renewcommand{\songtarget}[2]| +% | {\pdfbookmark[#1]{|\mac{thesongnum}|. |\mac{songtitle}|}{#2}}| +% |\renewcommand{\songlink}[2]{\hyperlink{#1}{#2}}| +% \end{codeblock} +% +% \noindent +% To enable links but not bookmarks, use: +% +% \begin{codeblock} +% |\renewcommand{\songtarget}[2]{\hypertarget{#2}{\relax}}| +% |\renewcommand{\songlink}[2]{\hyperlink{#1}{#2}}| +% \end{codeblock} +% +% \noindent +% To disable both bookmarks and links, use: +% +% \begin{codeblock} +% |\renewcommand{\songtarget}[2]{}| +% |\renewcommand{\songlink}[2]{#2}| +% \end{codeblock} +% +% \paragraph{Alphabetization Options.} +% \DescMacro{titleprefixword} +% In English, when a title begins with ``The'' or ``A'', it is traditional to +% move these words to the end of the title and sort the entry by the following +% word. +% So for example, ``The Song Title'' is typically indexed as +% ``Song Title, The''. +% To change this default behavior, you can use |\titleprefixword| in the +% document preamble to identify each word to be moved to the end whenever +% it appears as the first word of a title index entry. +% For example, to cause the word ``I'' to be moved to the end of title index +% entries, one could say, +% +% \begin{codeblock} +% |\titleprefixword{I}| +% \end{codeblock} +% +% \noindent +% The first use of |\titleprefixword| overrides the defaults, so if you also +% want to continue to move ``The'' and ``A'' to the end of entries, you must +% also say |\titleprefixword{The}| and |\titleprefixword{A}| explicitly. +% This macro may only be used in the document preamble but may be used +% multiple times to declare multiple prefix words. +% +% \paragraph{Special Words In Song Info.} +% \DescMacro{authsepword} +% When parsing author index entries, the word ``and'' is recognized by the +% |songidx| program as a conjunctive that separates author names. +% To override this default and specify a different conjunctive, use the +% |\authsepword| macro one or more times in the document preamble. +% For example, to instead treat ``und'' as a conjunctive, you could say, +% +% \begin{codeblock} +% |\authsepword{und}| +% \end{codeblock} +% +% \noindent +% The first use of |\authsepword| and each of the following macros overrides +% the default, so if you also want to continue to treat ``and'' as a +% conjunctive, you must also say |\authsepword{and}| explicitly. +% The |\authsepword| macro and each of the following macros may only be used +% in the document preamble but may be used multiple times to declare multiple +% special words. +% +% \DescMacro{authbyword} +% When parsing author index entries, the word ``by'' is recognized as a +% keyword signaling that the index entry should only include material +% in the current list item that follows the word ``by''. +% So for example, ``Music by J.S. Bach'' is indexed as ``Bach, J.S.'' +% rather than ``Bach, Music by J.S.'' +% To recognize a different word instead of ``by'', you can use |\authbyword| +% in the document preamble. +% For example, to recognize ``durch'' instead, you could say +% +% \begin{codeblock} +% |\authbyword{durch}| +% \end{codeblock} +% +% \DescMacro{authignoreword} +% When parsing author index entries, if a list item contains the word +% ``unknown'', that item is ignored and is not indexed. +% This prevents items like ``Composer unknown'' from being indexed as names. +% To cause the indexer to recognize and ignore a different word, you can +% use the |\authignoreword| macro in the document preamble. +% For example, to ignore author index entries containing the word +% ``unbekannt'', you could say, +% +% \begin{codeblock} +% |\authignoreword{unbekannt}| +% \end{codeblock} +% +% \subsection{Page Headers and Footers} +% +% In \LaTeX, page headers and footers are defined using a system of +% invisible \emph{marks} that get inserted into the document at the +% beginning of each logical unit of the document (e.g., each section, song, +% verse, and chorus). +% The headers and footers are then defined so as to refer to the first +% and/or last invisible mark that ends up on each page once the document +% is divided into pages. +% This section describes the marks made available by the \Songs{} package. +% For more detailed information about the marks already provided by +% \LaTeX{} and how to use them, consult any \LaTeX{} user manual. +% +% \DescMacro{songmark} +% \DescMacro{versemark} +% \DescMacro{chorusmark} +% To add song information to page headings and footers, redefine |\songmark|, +% |\versemark|, or |\chorusmark| to add the necessary \TeX{} marks to the +% current page whenever a new song, verse, or chorus begins. +% These macros expect no arguments; to access the current song's +% information including titles, use the macros documented in +% \S\ref{sec:songinfo}. +% To access the current song's number or the current verse's number, use +% \mac{thesongnum} or \mac{theversenum} (see \S\ref{sec:numbering}). +% For example, to include the song number in the page headings produced by +% \LaTeX's |\pagestyle{myheadings}| feature, you could redefine |\songmark| +% as follows: +% +% \begin{codeblock} +% |\renewcommand{\songmark}{\markboth{|\mac{thesongnum}|}{|\mac{thesongnum}|}}| +% \end{codeblock} +% +% \subsection{Defining New Beginsong Keyvals}\label{sec:newkey} +% +% \DescMacro{newsongkey} +% The \mac{beginsong} macro supports several optional keyval parameters for +% declaring song information, including \env{by=}, \env{sr=}, and \env{cr=}. +% Users can define their own additional keyvals as well. +% To do so, use the |\newsongkey| macro, which has the syntax +% +% \begin{codeblock} +% |\newsongkey{|\meta{keyname}|}{|\meta{initcode}|}[|\meta{default}|]{|\meta{setcode}|}| +% \end{codeblock} +% +% \noindent +% Here, \meta{keyname} is the name of the new key for the keyval, +% \meta{initcode} is \LaTeX{} code that is executed at the start of each +% \mac{beginsong} line before the \mac{beginsong} arguments are processed, +% \meta{default} (if specified) is the default value used for the keyval when +% \meta{keyname} appears in \mac{beginsong} without a value, +% and \meta{setcode} is macro code that is executed whenever +% \meta{key} is parsed as part of the \mac{beginsong} keyval arguments. +% In \meta{setcode}, |#1| expands to the value given by the user for the +% keyval (or to \meta{default} if no value was given). +% +% For example, to define a new song key called |arr| which stores its +% value in a macro called |\arranger|, one could write: +% +% \begin{codeblock} +% |\newcommand{\arranger}{}| +% |\newsongkey{arr}{\def\arranger{}}| +% | {\def\arranger{Arranged by #1\par}}| +% \end{codeblock} +% +% \noindent +% Then one could redefine \mac{extendprelude} to print the arranger below the +% other song header information: +% +% \begin{codeblock} +% |\renewcommand{\extendprelude}{| +% | |\mac{showrefs}\mac{showauthors} +% | {\bfseries\arranger}| +% |}| +% \end{codeblock} +% +% \noindent +% A \mac{beginsong} line could then specify the song's arranger as follows: +% +% \begin{codeblock} +% \mac{beginsong}|{The Title}[arr={R. Ranger}]| +% $\vdots$ +% \mac{endsong} +% \end{codeblock} +% +% \noindent This produces +% +% \begin{sample} +% \setcounter{songnum}{1}% +% \vskip1pt% +% \newcommand\arranger{}% +% \newsongkey{arr}{\def\arranger{}}% +% {\def\arranger{Arranged by #1\par}}% +% \renewcommand{\extendprelude}{ +% \showrefs\showauthors +% {\bfseries\arranger} +% }% +% \beginsong{The Title}[arr={R. Ranger}] +% \endsong +% \renewcommand{\extendprelude}{}% +% \end{sample} +% +% For more detailed information about keyvals and how they work, consult the +% documentation for David Carlisle's |keyval| package, which comes standard +% with most \LaTeXe{} installations. +% +% \subsection{Font Kerning Corrections} +% +% \paragraph{Chord Overstriking.} +% In order to conserve space and keep songs readable, the \Songs{} package +% pushes chords down very close to the lyrics with which they are paired. +% Unfortunately, this can sometimes cause low-hanging characters in chord +% names to overstrike the lyrics they sit above. +% For example, +% +% \example|\[(Gsus4/D)]Overstrike|\produces{\[(Gsus4/D)]Overstrike} +% \eat\] +% +% \noindent +% Note that the parentheses and slash symbols in the chord name have +% invaded the lyric that sits beneath them. +% +% \DescMacro{chordlocals} +% The best solution to this problem is to use a font for chord names that +% minimizes low-hanging symbols; but if you lack such a font, then the +% following trick works pretty well. +% Somewhere in the preamble of your document, you can write the following +% \LaTeX{} code: +% +% \begin{codeblock} +% |\renewcommand{\chordlocals}{\catcode`(\active| +% | \catcode`)\active| +% | \catcode`/\active}| +% |\newcommand{\smraise}[1]{\raise2pt\hbox{\small#1}}| +% |\newcommand{\myslash}{\smraise/}| +% |\newcommand{\myopenparen}{\smraise(|\eat)|}| +% |\newcommand{\mycloseparen}{\smraise)}| +% |{\chordlocals| +% | \global\let(\myopenparen| +% | \global\let)\mycloseparen| +% | \global\let/\myslash}| +% \end{codeblock} +% +% \noindent +% This sets the |/|, |(|, and |)| symbols as active characters whenever they +% appear within chord names. +% \ImplOrDesc +% {(See \S\ref{sec:chordlocals} for documentation of the +% \texttt{\string\chordlocals} hook.)} +% {(Recompile this documentation to include the implementation section +% for more information about the \texttt{\string\chordlocals} macro.)} +% Each active character is defined so that it produces a smaller, raised +% version of the original symbol. +% The result is as follows: +% +% \renewcommand{\chordlocals}{\catcode`(\active +% \catcode`)\active +% \catcode`/\active} +% \newcommand{\smraise}[1]{\raise2pt\hbox{\small#1}} +% \newcommand{\myslash}{\smraise/} +% \newcommand{\myopenparen}{\smraise(} +% \newcommand{\mycloseparen}{\smraise)} +% {\chordlocals +% \global\let(\myopenparen +% \global\let)\mycloseparen +% \global\let/\myslash} +% +% \example|\[(Gsus4/D)]Overstrike (fixed)|\produces{\[(Gsus4/D)]Overstrike (fixed)} +% \eat\] +% +% \renewcommand\chordlocals{} +% +% \noindent +% As you can see, the low-hanging symbols have been elevated so that they +% sit above the baseline, correcting the overstrike problem. +% +% \paragraph{Scripture Font Quotation Marks.} +% \DescMacro{shiftdblquotes} +% The \Songs{} package compensates for a kerning problem in the Zaph Chancery +% font (used to typeset scripture quotations) by redefining the |``| and |''| +% token sequences to be active characters that yield double-quotes shifted +% 1.1 points and 2 points left, respectively, of their normal positions. +% If you use a different font size for scripture quotations, then you can use +% the |\shiftdblquotes| macro when redefining \mac{scripturefont} to change +% this kerning correction. +% For example, +% +% \begin{codeblock} +% |\renewcommand{|\mac{scripturefont}|}{| +% | \usefont{OT1}{pzc}{mb}{it}| +% | \shiftdblquotes{-1pt}{-2pt}{-3pt}{-4pt}| +% |}| +% \end{codeblock} +% +% \noindent +% removes 1 point of space to the left and 2 points of space to the +% right of left-double-quote characters, and 3 points to the left and 4 points +% to the right of right-double-quotes, within scripture quotations. +% +% \section{Informational Macros}\label{sec:songinfo} +% +% The macros described in this section can be used to retrieve information +% about the current song. +% This can be used when redefining \mac{extendprelude}, \mac{extendpostlude}, +% \mac{makeprelude}, \mac{makepostlude}, \mac{songmark}, \mac{versemark}, or +% \mac{chorusmark}, or any other macros that might typeset this information. +% +% \DescMacro{songauthors} +% To get the current song's list of authors (if any) use |\songauthors|. +% This yields the value of the \env{by=} key used in the \mac{beginsong} +% line. +% +% \DescMacro{songrefs} +% To get the current song's list of scripture references (if any) use +% |\songrefs|. +% This yields the value of the \env{sr=} key used in the \mac{beginsong} +% line, but modified with hyphens changed to en-dashes and spaces falling +% within a list of verse numbers changed to thin spaces for better +% typesetting. +% In addition, various penalties have been added to inhibit line breaks +% in strange places and encourage line breaks in others. +% +% \DescMacro{songcopyright} +% To get the current song's copyright info (if any), use |\songcopyright|. +% This yields the value of the \env{cr=} key used in the \mac{beginsong} line. +% +% \DescMacro{songlicense} +% To get the current song's licensing information (if any), use +% |\songlicense|. +% This yields the value of the \env{li=} key used in the \mac{beginsong} +% line, or whatever text was declared with \mac{setlicense}. +% +% \DescMacro{songtitle} +% The |\songtitle| macro yields the current song's title. +% By default this is the first title provided in the \mac{beginsong} line. +% The \mac{nexttitle} and \mac{foreachtitle} macros (see below) cause it +% to be set to the current song's other titles, if any. +% +% \DescMacro{resettitles} +% To get the current song's primary title (i.e., the first title specified +% in the song's \mac{beginsong} line), execute |\resettitles|. +% This sets the |\songtitle| macro to be the song's primary title. +% +% \DescMacro{nexttitle} +% To get the song's next title, execute |\nexttitle|, which +% sets |\songtitle| to be the next title in the song's list of titles +% (or sets |\songtitle| to |\relax| if there are no more titles). +% +% \DescMacro{foreachtitle} +% The |\foreachtitle| macro accepts \LaTeX{} code as its single +% argument and executes it once for each (remaining) song title. +% Within the provided code, use |\songtitle| to get the current title. +% For example, the following code generates a comma-separated list of all +% of the current song's titles: +% +% \begin{codeblock} +% \mac{resettitles} +% \mac{songtitle} +% \mac{nexttitle} +% |\foreachtitle{, |\mac{songtitle}|}| +% \end{codeblock} +% +% \DescMacro{songlist} +% When \mac{includeonlysongs} is used to extract a partial list of songs, the +% |\songlist| macro expands to the comma-separated list of songs that is being +% extracted. +% Redefining |\songlist| within the document preamble alters the list of +% songs to be extracted. +% Redefining it after the preamble may have unpredictable results. +% +% \section{Index Generation} +% +% The material in this section describes macros provided by the \Songs\ +% package that are used during the automatic generation of the song book +% indexes. +% Since index generation is automatic, document authors should not +% normally need to use any of these macros directly. +% The documentation in this section is therefore provided purely for +% completeness and for informational purposes. +% For instructions on how to automatically generate indexes when compiling +% a song book, see \S\ref{sec:compiling}. +% For info on how to customize the appearance of indexes, see +% \S\ref{sec:idxcust}. +% +% Automatic generation of song book indexes is a three stage process: +% +% \begin{enumerate} +% +% \item +% Each time a song book \LaTeX{} file is compiled, an auxiliary file named +% \meta{filename}|.sxd| is written out for each \meta{filename} +% defined using \mac{newindex}, \mac{newauthorindex}, or \mac{newscripindex}. +% These |.sxd| files are plain text files that can be viewed using any +% standard text editor. +% They begin with a line identifying the type of index (title, author, or +% scripture) and then contain triples of lines, one triple for each song to +% appear in the index. +% The first line of a triple has the information by which the song is to be +% indexed (a title, author, or scripture reference). +% The second line has the song's number in the book (yielded by +% \mac{thesongnum}). +% The third line is an identifying label for the song used in hyperlinking. +% +% \item +% Once the |.sxd| files have been generated, an external program is used +% to transform each |.sxd| file into a |.sbx| file. +% Since the standard |makeindex| program provided with \LaTeX{} is not powerful +% enough to sort scripture references, distributions of \Songs{} package come +% with a specialized |songidx| program to do this. +% +% \item +% The |.sbx| files produced by the |songidx| program are then read +% in by the \mac{showindex} macro next time the source document is +% compiled using \LaTeX. +% These |.sbx| files consist of the macros and environments described below. +% +% \end{enumerate} +% +% \DescEnv{idxblock} +% In indexes that are blocked off into sections, one for each letter of the +% alphabet, the \meta{filename}|.sbx| files generated for that index +% consist of a series of |idxblock| environments, one for each such section. +% An |idxblock| environment begins and ends with +% +% \begin{codeblock} +% |\begin{idxblock}{|\meta{letter}|}| +% $\vdots$ +% |\end{idxblock}| +% \end{codeblock} +% +% \noindent +% where \meta{letter} is the letter of the alphabet for that block. +% +% \DescMacro{idxentry} +% \DescMacro{idxaltentry} +% The index entries themselves are created by lines of the form +% +% \begin{codeblock} +% |\idxentry{|\meta{leftside}|}{|\meta{rightside}|}| +% |\indexaltentry{|\meta{leftside}|}{|\meta{rightside}|}| +% \end{codeblock} +% +% \noindent +% each of which creates an index entry with \meta{leftside} on the left, +% followed by a series of dots, followed by \meta{rightside} on the +% right. +% The |\indexentry| macro is used for ``normal'' entries (e.g., titles in a +% title index), and |\indexaltentry| is used for ``alternate'' entries +% (e.g., lyric lines in a title index). +% +% Within \meta{rightside}, multiple items are separated with |\\| +% macros instead of commas. +% When used in an index |.sbx| file, the |\\| macro produces a comma followed +% by some complex spacing that allows index lines to be broken suitably if +% they are too long to fit in one physical line. +% +% \section{Other Resources} +% +% There are a number of other \LaTeX{} packages available for typesetting +% songs, tablature diagrams, or song books. +% Probably the best of these is the \Rath{} package by Christopher Rath +% (\href{http://rath.ca/Misc/Songbook/}{{\tt http://rath.ca/Misc/Songbook/}}). +% Most of the differences between other packages and this one are intentional; +% the following is a summary of where I've adopted various differing design +% decisions and why. +% +% \bigskip +% +% \paragraph{Ease of Song Entry.} +% Much of the \Songs{} package programming is devoted to easing the burden of +% typing chords. +% With most \LaTeX{} song book packages the user types chords using a standard +% \LaTeX{} macro syntax like |\chord{|\meta{chord}|}{|\meta{lyric}|}|. +% The \Songs{} package uses a less conventional +% |\[|\meta{chord}|]|\meta{lyric}\eat\] syntax for several +% reasons detailed below. +% +% First, macros in the standard \LaTeX{} syntax require more key-presses +% than macros in the \Songs{} package's syntax. +% This can become become very taxing when typing up a large book. +% Chords often appear as frequently as one per syllable, especially in hymns, +% so keeping the syntax as brief as possible is desirable. +% +% Second, the standard \LaTeX{} macro syntax requires the user to estimate how +% much of the \meta{lyric} will lie below the chord (because the \meta{lyric} +% part must be enclosed in braces) whereas the \Songs{} package's syntax does +% not. +% Estimating this accurately can be quite difficult, since in many cases the +% \meta{lyric} part must include punctuation or multiple words to get proper +% results. +% The \Songs{} package automates this for the user, significantly easing the +% task of chord-entry. +% +% Third, unlike the standard \LaTeX{} chord syntax, the \Songs{} package's +% syntax handles all hyphenation of chorded lyrics fully automatically. +% Extra hyphenation must be introduced in chord books wherever a chord +% is wider than the syllable it sits above. +% With the standard \LaTeX{} chord syntax such hyphenation must be +% introduced manually by the user (usually via a special hyphenation macro), +% but the \Songs{} package does this automatically. +% +% Fourth and finally, some other packages allow the user to use ``|b|'' +% in a \meta{chord} to produce a flat symbol, whereas the \Songs{} package +% requires an ``|&|'' instead. +% Using ``|b|'' is more intuitive but prevents the +% use of ``|b|'' for any other purpose within a \meta{chord}, such as to +% produce a literal ``b'' or to type another macro name like |\hbox| that +% contains a ``b''. +% Consequently, the \Songs{} package uses the less obvious ``|&|'' symbol to +% produce flat symbols. +% +% \paragraph{Song Structure.} +% The \Songs{} package provides a relatively small number of macros for +% typesetting high-level song structure, including verses, choruses, +% textual comments, and conditional macros that indicate that certain sections +% should go in chord books but not lyric books. +% These can be combined to typeset more sophisticated structures such as +% intros, bridges, brackets, endings, and the like. +% This is done in lieu of providing a specific macro for each of these +% structures since it results in greater flexibility and fewer macros for +% users to learn. +% +% \paragraph{Multiple columns.} +% The \Songs{} package was designed from the ground up to produce song books +% with many songs per page, arranged in multiple columns. +% As a result, it includes elaborate support for many features not found in +% most other packages, such as automatic column balancing, completely +% customizable song header and song footer blocks, and facilities for adding +% beautiful scripture quotations to fill in gaps between songs. +% +% \paragraph{Indexes.} +% Another major feature of the \Songs{} package is its support for a variety +% of different index types, most notably indexes arranged by scripture +% reference. +% Scripture indexes can be invaluable for planning services around particular +% sermons or topics. +% The \Songs{} package allows book authors to specify the names and preferred +% ordering of books of the bible, and automatically handles complex issues +% like overlapping verse ranges to produce an easy-to-read, compact, and +% well-ordered index. +% Other supported indexes include those sorted by author, by title, and by +% notable lines of lyrics. +% +% \paragraph{Automatic Transposition.} +% The \Songs{} package has a facility for automatically transposing songs, and +% even generating chord books that print the chords in multiple keys (e.g., so +% that a pianist and guitarist using a capo can play together from the same +% book). +% +% \bigskip +% +% The \Songs{} package was developed entirely independently of all other +% \LaTeX{} song book packages. +% I originally developed the set of \LaTeX{} macros that eventually became +% the \Songs{} package in order to typeset a song book for the Graduate +% Christian Fellowship (GCF) at Cornell University, and the Cornell +% International Christian Fellowship (CICF). +% Once I had fine-tuned my package to be sufficiently versatile, I decided +% to release it for public use. +% At that time I noticed the \Rath{} package and others, and wrote this +% summary of the most prominent differences. +% +% For information on more song-typesetting resources for \LaTeX, I recommend +% consulting the documentation provided with the \Rath{} package. +% It includes an excellent list of other resources that might be of interest +% to creators of song books. +% +% \section{GNU General Public License}\label{sec:license} +% +% \begingroup\small +% +% \begin{center} +% {\large\sc Terms and Conditions For \\

However, as a +% special exception, the source code distributed need not include +% anything that is normally distributed (in either source or binary +% form) with the major components (compiler, kernel, and so on) of the +% operating system on which the executable runs, unless that component +% itself accompanies the executable. +% +% If distribution of executable or object code is made by offering +% access to copy from a designated place, then offering equivalent +% access to copy the source code from the same place counts as +% distribution of the source code, even though third parties are not +% compelled to copy the source along with the object code. +% +% \item +% You may not copy, modify, sublicense, or distribute the Program +% except as expressly provided under this License.

If you cannot +% distribute so as to satisfy simultaneously your obligations under this +% License and any other pertinent obligations, then as a consequence you +% may not distribute the Program at all. For example, if a patent +% license would not permit royalty-free redistribution of the Program by +% all those who receive copies directly or indirectly through you, then +% the only way you could satisfy both it and this License would be to +% refrain entirely from distribution of the Program. +% +% If any portion of this section is held invalid or unenforceable under +% any particular circumstance, the balance of the section is intended to +% apply and the section as a whole is intended to apply in other +% circumstances. +% +% It is not the purpose of this section to induce you to infringe any +% patents or other property right claims or to contest validity of any +% such claims; this section has the sole purpose of protecting the +% integrity of the free software distribution system, which is +% implemented by public license practices.

\end{enumerate} +% +% \endgroup +% +% \StopEventually{\PrintIndex} +% +% \clearpage +% \section{Implementation} +% +% The following provides the verbatim implementation of the \Songs{} \LaTeX{} +% package, along with commentary on how it works. +% In general, macro names that contain a |@| symbol are not intended to be +% directly accessible by the outside world; they are for purely internal use. +% All other macros are intended to be used or redefined by document authors. +% +% Most of the macros likely to be of real interest to song book authors can +% be found in \S\ref{sec:impparams}. +% To find the implementation of any particular macro, the index at the end +% of this document should prove helpful. +% +% The unwary \TeX er may wonder at the rather large size of the +% implementation. +% The volume and complexity of the code stems mainly from the following +% challenging features: +% \begin{itemize} +% \item Putting chords above lyrics fully automatically requires building an +% entire lyric-parser in \LaTeX{} (see \S\ref{sec:lyricscan}). +% \item Avoiding page-turns within songs without prohibiting column-breaks +% requires building a completely new page-breaking algorithm +% (see \S\ref{sec:pagebuilder}). +% \item The package must be able to generate an astonishing number of document +% variants from a common source: lyric-only books, chorded books, digital +% slides, transparency slides, selected song subsets, transposed songs, and +% combinations of the above. +% This is like putting six or more packages into one. +% \item Song book indexes are far more complex than those for a prose book. +% See \S\ref{sec:indexgen} for some of the difficulties involved. +% \end{itemize} +% +% \subsection{Initialization} +% +% The code in this section detects any \TeX{} versioning or configuration +% settings that are relevant to the rest of the song book code. +% +% \begin{macro}{\ifSB@etex} +% Numerous enhancements are possible when using

columns created during the spitting +% process. +% The macro arguments are: +% \begin{enumerate} +% \item an integer (positive or zero) indicating whether box $b$ should be +% fully emptied and committed as columns (if positive), or whether its +% final less-than-column-height remainder should be reserved as an in-progress +% column (if zero); +% \item the box $b$ to split; +% \item a count register $i$ equaling the column index (zero or greater) +% where the content of $b$ is to begin; and +% \item the desired column height. +% \end{enumerate} +% Box $b$ is split and $i$ is incremented until $i$ reaches +% |\SB@numcols| or $b$ is emptied. +% If $b$ is emptied and the first argument is 0, the final column is \emph{not} +% contributed; instead it is left in $b$ and $i$ is left equal to the index +% of the column that would have been added if $b$ had been emptied. +% This allows the next call to reconsider whether to end the +% current column here or add some or all of the next contribution to it. +% Otherwise, if $b$ is emptied and the first argument is positive, the final +% column is contributed and $i$ is set to one greater than the index of that +% column. +% (If $i$ reaches |\SB@numcols| before $b$ is emptied, the first argument is +% ignored.) +% +% Box $b$ and count register $i$ are globally modified. +% If |\SB@updatepage| is not redefined, boxes |\SB@pgbox|

argument is zero): +% First, the final split that empties box $b$ is ``undone'' by reverting to a +% backup copy made before each split. +% Second, any underfull box warnings for this final split are suppressed by +% temporarily adding infinite-stretch |\vfil| glue to the bottom of the box. +% This strategy preserves underfull and overfull box warnings for the columns +% that are actually

John 1:1| and |Song of Solomon 1:1| become |2~John~1:1| and +% |Song~of~Solomon~1:1|, respectively. +% (2)~Spaces between a semicolon and a book name are lengthened to en-spaces. +% (3)~Single hyphens are lengthened to en-dashes (|--|). +% (4)~Non-breaking, thin spaces are appended to commas not followed by a +% space. For example |John 3:16,17| becomes |John~3:16,\nobreak\thinspace17|. +% (5)~Everything within an explicit group is left unchanged, allowing the +% user to suppress all of the above as desired. +% +%

Scanning}\label{sec:lyricscan} +% +% The obvious way to create a chord macro is as a normal macro with +% two arguments, one for the chord name and one for the lyrics to go +% under the chord---e.g.~|\chord{|\meta{chordname}|{|\meta{lyric}|}|. +% However, in practice such a macro is extremely cumbersome and +% difficult to use. +% The problem is that in order to use such a macro properly, the user +% must remember a bunch of complex style rules that govern what +% part of the lyric text needs to go in the \meta{lyric} parameter and +% what part should be typed after the closing brace. +% To avoid separating a word from its trailing punctuation, the +% \meta{lyric} parameter must often include punctuation but not certain +% special punctuation like hyphens, should include the rest of the +% word but not if there's another chord in the word, should omit +% measure bars but only if measure bars are being shown, etc. +% This is way too difficult for the average user. +% +% To avoid this problem, we define chords using a one-argument macro +% (the argument is the chord name), but with no explicit argument for +% the lyric part. +% Instead, the macro scans ahead in the input stream, automatically +% determining what portion of the lyric text that follows should be +% sucked in as an implicit second argument. +% The following code does this look-ahead scanning. +% +% \begin{macro}{\ifSB@wordends} +% \begin{macro}{\ifSB@brokenword} +% Chord macros must look ahead in the input stream to see whether this chord +% is immediately followed by whitespace

At present there +% are four types: +% \begin{enumerate} +% \item A ``large'' index has a separate section for each capital letter and +% is printed in two columns. +% \item A ``small'' index has only a single column, centered, and has no +% sections. +% \item A ``scripture'' index has three columns and each entry has a +% comma-separated list of references. +% \item An ``author'' index is like a large index except in bold and without +% the sectioning. +% \end{enumerate} +% ``Large'' and ``small'' indexes will be chosen automatically based on the +% number of index entries when building a song index. The other two types are +% designated by the user. +% +% As is typical of \LaTeX{} indexes, generation of song book indexes requires +% two passes of document compilation. During the first pass, data files are +% generated with song titles, authors, and scripture references. An external +% program is then used to produce \LaTeX{} source files from those data files. +% During the second pass of document compilation, those source files are +% imported to typeset all the indexes and display them in the document. +% +% Internally, this package code uses a \emph{four} step process to move +% the index data from the source |.tex| file to the |.sxd| data files. +% \begin{enumerate} +% \item While the current song box is in the midst of construction, +% the data is stored in a box of non-immediate write whatsit nodes. +% \item The whatsits are migrated out to the top of the song box when +% it is finalized at |\endsong|. +% \item When the song box is shipped out to the output file, \TeX{} expands +% the whatsits, causing the data to be written to the |.sxc| auxiliary file. +% \item At the |\end{document}| line, the |.sxc| is processed multiple +% times---once for each index---to split the data into the respective +% |.sxd| files. +% \end{enumerate} +% The first and second steps allow index references to point to the +% beginning of the song no matter where the indexing commands appear +% within the song. +% The third step allows \TeX{} to drop index entries that refer to +% songs that do not actually appear in the output (e.g., because of +% |\includeonlysongs|). +% It also allows index entries to refer to information that is only decided +% at shipout time, such as page numbers. +% The fourth step allows all indexing to be accomplished with at most one +% write register. +% \LaTeX{} provides extremely few write registers, so using as +% few as possible is essential for supporting books with many indexes. +% +% \begin{macro}{\songtarget}\MainImpl{songtarget} +% This macro is invoked by each \env{song} environment with two arguments: +% (1) a suggested pdf bookmark index level, and +% (2) a target name to which hyperlinks for this song in the index will refer. +% The macro is expected to produce a suitable pdf bookmark entry and/or +% link target. +% The default definition tries to use |\pdfbookmark| if generating a PDF, +% and resorts to |\hypertarget| (if it exists) otherwise. +% The user can redefine the macro to customize how and whether bookmarks +% and/or links are created. +% \begin{macrocode} +\newcommand\songtarget[2]{% + \ifnum\@ne=0\ifSB@pdf\ifx\pdfbookmark\undefined\else% + \ifx\pdfbookmark\relax\else1\fi\fi\fi\relax% + \pdfbookmark[#1]{\thesongnum. \songtitle}{#2}% + \else\ifx\hypertarget\undefined% + \else\ifx\hypertarget\relax\else% + \hypertarget{#2}{\relax}% + \fi\fi\fi% +} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\songlink}\MainImpl{songlink} +% This macro is invoked by the index code to produce a link to a song target +% created by \mac{songtarget}. +% Its two arguments are: +% (1) the target name (same as the second argument to \mac{songtarget}, and +% (2) the text that is to be linked. +% The default implementation uses |\hyperlink| if it exists;
