By +"TeX implementation", we mean all of the standard programs developed by +the Stanford TeX project directed by Donald E. Knuth: Metafont, +DVItype, GFtoDVI, BibTeX, Tangle, etc., as well as TeX itself. Other +programs are also included: DVIcopy, written by Peter Breitenlohner, +MetaPost and its utilities (derived from Metafont), by John Hobby, etc. + + General strategy: Web2c works, as its name implies, by translating +the WEB source in which TeX is written into C source code. Its output is +not self-contained, however; it makes extensive use of many macros and +functions in a library (the `web2c/lib' directory in the sources). +Therefore, it will not work without change on an arbitrary WEB program. + + Availability: All of Web2c is freely available--"free" both in the +sense of no cost (free ice cream) and of having the source code to +modify and/or redistribute (free speech). *Note unixtex.ftp: +(kpathsea)unixtex.ftp, for the practical details of how to obtain Web2c. + + Different parts of the Web2c distribution have different licensing +terms, however, reflecting the different circumstances of their +creation; consult each source file for exact details. The main +practical implication for redistributors of Web2c is that the +executables are covered by the GNU General Public License, and +therefore anyone who gets a binary distribution must also get the +sources, as explained by the terms of the GPL (*note Copying: +(kpathsea)Copying.). The GPL covers the Web2c executables, including +`tex', because the Free Software Foundation sponsored the initial +development of the Kpathsea library that Web2c uses. The basic source +files from Stanford, however, have their own copyright terms or are in +the public domain, and are not covered by the GPL. + + History: Tomas Rokicki originated the TeX-to-C system in 1987, +working from the first change files for TeX under Unix, which were done +primarily by Howard Trickey and Pavel Curtis. Tim Morgan then took over +development and maintenance for a number of years; the name changed to +Web-to-C somewhere in there. In 1990, Karl Berry became the +maintainer. He made many changes to the original sources, and started +using the shorter name Web2c. In 1997, Olaf Weber took over. Dozens of +other people have contributed; their names are listed in the +`ChangeLog' files. + + Other acknowledgements: The University of Massachusetts at Boston +(particularly Rick Martin and Bob Morris) has provided computers and ftp +access to me for many years. Richard Stallman at the Free Software +Foundation employed me while I wrote the original path searching library +(for the GNU font utilities). (rms also gave us Emacs, GDB, and GCC, +without which I cannot imagine developing Web2c.) And, of course, TeX +would not exist in the first place without Donald E. Knuth. + + Further reading: *Note References::. + + +File: web2c.info, Node: Installation, Next: Commonalities, Prev: Introduction, Up: Top + +2 Installation +************** + +(A copy of this chapter is in the distribution file `web2c/INSTALL'.) + +Installing Web2c is mostly the same as installing any other +Kpathsea-using program. Therefore, for the basic steps involved, see +*Note Installation: (kpathsea)Installation. (A copy is in the file +`kpathsea/INSTALL'.) + + One peculiarity to Web2c is that the source distribution comes in two +files: `web.tar.gz' and `web2c.tar.gz'. You must retrieve and unpack +them both. (We have two because the former archive contains the very +large and seldom-changing original WEB source files.) *Note +unixtex.ftp: (kpathsea)unixtex.ftp. + + Another peculiarity is the MetaPost program. Although it has been +installed previously as `mp', as of Web2c 7.0 the installed name is now +`mpost', to avoid conflict with the `mp' program that does +prettyprinting. This approach was recommended by the MetaPost author, +John Hobby. If you as the TeX administrator wish to make it available +under its shorter name as well, you will have to set up a link or some +such yourself. And of course individual users can do the same. + + For solutions to common installation problems and information on how +to report a bug, see the file `kpathsea/BUGS' (*note Bugs: +(kpathsea)Bugs.). See also the Web2c home page, +`http://www.tug.org/web2c'. + + Points worth repeating: + + * Before starting the standard compilation and installation you must + install the basic fonts, macros, and other library files. *Note + Installation: (kpathsea)Installation. + + * If you do not wish to use the standard file locations, see *Note + Changing search paths: (kpathsea)Changing search paths. + + * Some Web2c features are enabled or disabled at `configure' time, + as described in the first section below. + + +* Menu: + +* configure options:: Especially --with and --enable. +* Compile-time options:: Unusual -D's. +* Additional targets:: Breaking down the task. +* Triptrap:: Running the torture tests. +* Runtime options:: Array sizes and the like. + + +File: web2c.info, Node: configure options, Next: Compile-time options, Up: Installation + +2.1 `configure' options +======================= + +This section gives pointers to descriptions of the `--with' and +`--enable' `configure' arguments that Web2c accepts. Some are specific +to Web2c, others are generic to all Kpathsea-using programs. + + For a list of all the options `configure' accepts, run `configure +--help'. The generic options are listed first, and the +package-specific options come last. + + For a description of the generic options (which mainly allow you to +specify installation directories) and basic `configure' usage, see +*Note Running `configure' scripts: (autoconf)Invoking configure, a copy +is in the file `kpathsea/CONFIGURE'. + +`--disable-dump-share' + Do not make fmt/base/mem files sharable across different endian + architectures. *Note Hardware and memory dumps::. + +`--without-maketexmf-default' +`--without-maketexpk-default' +`--without-maketextfm-default' +`--with-maketextex-default' + Enable or disable the dynamic generation programs. *Note mktex + configuration: (kpathsea)mktex configuration. The defaults are + the inverse of the options, i.e., everything is enabled except + `mktextex'. + +`--enable-shared' + Build Kpathsea as a shared library. *Note Shared library: + (kpathsea)Shared library. + +`--with-editor=CMD' + Change the default editor invoked by the `e' interactive command. + *Note Editor invocation::. + +`--with-epsfwin' +`--with-hp2627win' +`--with-mftalkwin' +`--with-nextwin' +`--with-regiswin' +`--with-suntoolswin' +`--with-tektronixwin' +`--with-unitermwin' +`--with-x' +`--with-x-toolkit=KIT' +`--with-x11win' +`--with-x11' + Define Metafont graphics support; by default, no graphics support + is enabled. *Note Online Metafont graphics::. + +`--x-includes=DIR' +`--x-libraries=DIR' + Define the locations of the X11 include files and libraries; by + default, `configure' does its best to guess). *Note Optional + Features: (autoconf)Optional Features. A copy is in + `kpathsea/CONFIGURE'. + + +File: web2c.info, Node: Compile-time options, Next: Additional targets, Prev: configure options, Up: Installation + +2.2 Compile-time options +======================== + +In addition to the `configure' options listed in the previous section, +there are a few things that can be affected at compile-time with C +definitions, rather than with `configure'. Using any of these is +unusual. + + To specify extra compiler flags (`-DNAME' in this case), the +simplest thing to do is: + make XCFLAGS="CCOPTIONS" + You can also set the `CFLAGS' environment variable before running +`configure'. *Note configure environment: (kpathsea)configure +environment. + + Anyway, here are the possibilities: + +`-DFIXPT' +`-DNO_MF_ASM' + Use the original WEB fixed-point routines for Metafont and MetaPost + arithmetic calculations regarding fractions. By default, + assembly-language routines are used on x86 hardware with GNU C + (unless `NO_MF_ASM' is defined), and floating-point routines are + used otherwise. + +`-DIPC_DEBUG' + Report on various interprocess communication activities. *Note + IPC and TeX: IPC and TeX. + + +File: web2c.info, Node: Additional targets, Next: Triptrap, Prev: Compile-time options, Up: Installation + +2.3 Additional targets +====================== + +Web2c has several Make targets besides the standard ones. You can +invoke these either in the top level directory of the source +distribution (the one containing `kpathsea/' and `web2c/'), or in the +`web2c/' directory. + +`c-sources' + Make only the C files, translated from the Web sources, presumably + because you want to take them to a non-Unix machine. + +`formats' +`install-formats' + Make or install all the memory dumps (*note Memory dumps::). By + default, the standard plain formats plus `latex.fmt' are made. You + can add other formats by redefining the `fmts', `bases', and + `mems' variables. See the top of `web2c/Makefile' for the + possibilities. + +`fmts' +`install-fmts' + Make or install the TeX `.fmt' files. *Note Initial TeX::. + +`bases' +`install-bases' + Make or install the Metafont `.base' files. *Note Initial + Metafont::. + +`mems' +`install-mems' + Make or install the MetaPost `.mem' files. *Note Initial + MetaPost::. + +`triptrap' +`trip' +`trap' +`mptrap' + To run the torture tests for TeX, Metafont, and MetaPost + (respectively). See the next section. + + + +File: web2c.info, Node: Triptrap, Next: Runtime options, Prev: Additional targets, Up: Installation + +2.4 Trip, trap, and mptrap: Torture tests +========================================= + +To validate your TeX, Metafont, and MetaPost executables, run `make +triptrap'. This runs the trip, trap, and mptrap "torture tests". See +the files `triptrap/tripman.tex', `triptrap/trapman.tex', and +`triptrap/mptrap.readme' for detailed information and background on the +tests. + + The differences between your executables' behavior and the standard +values will show up on your terminal. The usual differences (these are +all acceptable) are: + + * string usage and table sizes; + + * glue set ratios; + + * `down4', `right4', and `y4' commands in DVItype output; + + * dates and times. + +Any other differences are trouble. The most common culprit in the past +has been compiler bugs, especially when optimizing. *Note TeX or +Metafont failing: (kpathsea)TeX or Metafont failing. + + The files `trip.diffs', `mftrap.diffs', and `mptrap.diffs' in the +`triptrap' directory show the standard diffs against the original +output. If you diff your diffs against these files, you should come up +clean. For example + make trip >&mytrip.diffs + diff triptrap/trip.diffs mytrip.diffs + + To run the tests separately, use the targets `trip', `trap', and +`mptrap'. + + To run simple tests for all the programs as well as the torture +tests, run `make check'. You can compare the output to the distributed +file `tests/check.log' if you like. + + +File: web2c.info, Node: Runtime options, Prev: Triptrap, Up: Installation + +2.5 Runtime options +=================== + +Besides the configure- and compile-time options described in the +previous sections, you can control a number of parameters (in +particular, array sizes) in the `texmf.cnf' runtime file read by +Kpathsea (*note Config files: (kpathsea)Config files.). + + Rather than exhaustively listing them here, please see the last +section of the distributed `kpathsea/texmf.cnf'. Some of the more +interesting values: + +`main_memory' + Total words of memory available, for TeX, Metafont, and MetaPost. + Must remake the format file after changing. + +`extra_mem_bot' + Extra space for "large" TeX data structures: boxes, glue, + breakpoints, et al. If you use PiCTeX, you may well want to set + this. + +`font_mem_size' + Words of font info available for TeX; this is approximately the + total size of all TFM files read. + +`hash_extra' + Additional space for the hash table of control sequence names. + Approximately 10,000 control sequences can be stored in the main + hash table; if you have a large book with numerous + cross-references, this might not be enough, and thus you will want + to set `hash_extra'. + + + Of course, ideally all arrays would be dynamically expanded as +necessary, so the only limiting factor would be the amount of swap space +available. Unfortunately, implementing this is extremely difficult, as +the fixed size of arrays is assumed in many places throughout the source +code. These runtime limits are a practical compromise between the +compile-time limits in previous versions, and truly dynamic arrays. (On +the other hand, the Web2c BibTeX implementation does do dynamic +reallocation of some arrays.) + + +File: web2c.info, Node: Commonalities, Next: TeX, Prev: Installation, Up: Top + +3 Commonalities +*************** + +Many aspects of the TeX system are the same among more than one +program, so we describe all those pieces together, here. + +* Menu: + +* Option conventions:: -- or -, = or ` ' for values. +* Common options:: --help --version --verbose, and TeX/MF/MP options. +* Path searching:: Features of the common path searching library. +* Output file location:: TEXMFOUTPUT allows output in places other than `.'. +* Three programs:: TeX, Metafont, and MetaPost have a lot in common. + + +File: web2c.info, Node: Option conventions, Next: Common options, Up: Commonalities + +3.1 Option conventions +====================== + +To provide a clean and consistent behavior, we chose to have all these +programs use the GNU function `getopt_long_only' to parse command +lines. However, we do use in a restricted mode, where all the options +have to come before the rest of the arguments. + + As a result, you can: + * use `-' or `--' to start an option name; + + * use any unambiguous abbreviation for an option name; + + * separate option names and values with either `=' or one or more + spaces; + + * use filenames that would otherwise look like options by putting + them after an option `--'. + + By convention, non-option arguments, if specified, generally define +the name of an input file, as documented for each program. + + If a particular option with a value is given more than once, it is +the last value that counts. + + For example, the following command line specifies the options `foo', +`bar', and `verbose'; gives the value `baz' to the `abc' option, and +the value `xyz' to the `quux' option; and specifies the filename +`-myfile-'. + + -foo --bar -verb -abc=baz -quux karl --quux xyz -- -myfile- + + +File: web2c.info, Node: Common options, Next: Path searching, Prev: Option conventions, Up: Commonalities + +3.2 Common options +================== + +All of these programs accept the standard GNU `--help' and `--version' +options, and several programs accept `--verbose'. Rather than writing +identical descriptions for every program, they are described here. + +`--help' + Print a usage message listing basic usage and all available + options to standard output, then exit successfully. + +`--verbose' + Print progress reports to standard output. + +`--version' + Print the version number to standard output, then exit + successfully. + + TeX, Metafont, and MetaPost have a number of additional options in +common: + +`-file-line-error' +`-no-file-line-error' + Change (or do not change) the way error messages are printed. The + alternate style looks like error messages from many compilers and + is easier to parse for some editors that invoke TeX. This option + used to be called `-file-line-error-style'. + +`-fmt=DUMPNAME' +`-base=DUMPNAME' +`-mem=DUMPNAME' + Use DUMPNAME instead of the program name or a `%&' line to + determine the name of the memory dump file read (`fmt' for TeX, + `base' for Metafont, `mem' for MetaPost). *Note Memory dumps::. + Also sets the program name to DUMPNAME if no `-progname' option + was given. + +`-halt-on-error' + Stop processing and exit when an error occurs, as opposed to the + normal process of trying to recover and continue. + +`-ini' + Enable the "initial" form of the program (*note Initial and + virgin::). This is implicitly set if the program name is `initex' + resp. `inimf' resp. `inimpost', although these variants are no + longer typically installed. + +`-interaction=STRING' + Set the interaction mode from the command line. The STRING must + be one of `batchmode', `nonstopmode', `scrollmode', or + `errorstopmode'. + +`-jobname=STRING' + Set the job name to STRING, instead of deriving it from the name + of the input file. + +`-kpathsea-debug=NUMBER' + Set path searching debugging flags according to the bits of NUMBER + (*note Debugging: (kpathsea)Debugging.). You can also specify + this in `KPATHSEA_DEBUG' environment variable (for all Web2c + programs). (The command line value overrides.) The most useful + value is `-1', to get all available output. + +`-output-directory=DIRNAME' + Specify the directory DIRNAME to which output files are written. + Also look for input files in DIRNAME first, before looking along + the normal search path. This is useful when you are in some + read-only distribution directory, perhaps on a CD-ROM, and want to + TeX some documentation, for example. Note that for input files + the "search" in DIRNAME does not use the full generality of the + search mechanism. This means that some files are not found there + even though you might expect them to be. + +`-parse-first-line' +`-no-parse-first-line' + Check or disable checking whether the first line of the main input + file starts with `%&', and parse it if it does. This line can be + used specify the format and/or a TCX file. + +`-progname=STRING' + Set program (and memory dump) name to STRING. This may affect the + search paths and other values used (*note Config files: + (kpathsea)Config files.). Using this option is equivalent to + making a link named STRING to the binary and then invoking the + binary under that name. *Note Memory dumps::. + +`-recorder' + Enable the filename recorder. This makes the program save a list + of the opened files into a file with (by default) extension + `.fls'. For Omega, this option is always on, and the file has + extension `.ofl'. + +`-translate-file=TCXFILE' + Use TCXFILE to define which characters are printable and + translations between the internal and external character sets. + Moreover, TCXFILE can be explicitly declared in the first line of + the main input file `%& -translate-file=TCXFILE'. This is the + recommended method for portability reasons. *Note TCX files::. + +`-8bit' + This option specifies that by default all characters should be + considered printable. If `-translate-file' was given as well, + then the TCX file may mark characters as non-printable. + +`-oem' + This option is specific to Windows. When specified, TeX engines + will use the OEM code page rather than the ANSI one to display + their messages. + + + +File: web2c.info, Node: Path searching, Next: Output file location, Prev: Common options, Up: Commonalities + +3.3 Path searching +================== + +All of the Web2c programs, including TeX, which do path searching use +the Kpathsea routines to do so. The precise names of the environment +and configuration file variables which get searched for particular file +formatted are therefore documented in the Kpathsea manual (*note +Supported file formats: (kpathsea)Supported file formats.). Reading +`texmf.cnf' (*note Config files: (kpathsea)Config files.), invoking +`mktex...' scripts (*note mktex scripts: (kpathsea)mktex scripts.), and +so on are all handled by Kpathsea. + + The programs which read fonts make use of another Kpathsea feature: +`texfonts.map', which allows arbitrary aliases for the actual names of +font files; for example, `Times-Roman' for `ptmr8r.tfm'. The +distributed (and installed by default) `texfonts.map' includes aliases +for many widely available PostScript fonts by their PostScript names. + + +File: web2c.info, Node: Output file location, Next: Three programs, Prev: Path searching, Up: Commonalities + +3.4 Output file location +======================== + +All the programs generally follow the usual convention for output files. +Namely, they are placed in the directory current when the program is +run, regardless of any input file location; or, in a few cases, output +is to standard output. + + For example, if you run `tex /tmp/foo', for example, the output will +be in `./foo.dvi' and `./foo.log', not `/tmp/foo.dvi' and +`/tmp/foo.log'. + + You can use the `-output-directory' option to cause all output files +that would normally be written in the current directory to be written +in the specified directory instead. *Note Common options::. + + If the current directory is not writable, and `-output-directory' is +not specified, the main programs (TeX, Metafont, MetaPost, and BibTeX) +make an exception: if the config file value `TEXMFOUTPUT' is set (it is +not by default), output files are written to the directory specified. + + +File: web2c.info, Node: Three programs, Prev: Output file location, Up: Commonalities + +3.5 Three programs: Metafont, MetaPost, and TeX +=============================================== + +TeX, Metafont, and MetaPost have a number of features in common. +Besides the ones here, the common command-line options are described in +the previous section. The configuration file options that let you +control some array sizes and other features are described in *Note +Runtime options::. + +* Menu: + +* Initial and virgin:: Making memory dumps vs. production runs. +* Memory dumps:: .fmt/.base/.mem files for fast startup. +* Editor invocation:: The `e' response at errors. +* \input filenames:: ~ and $ expansion in TeX/MF/MP. + + +File: web2c.info, Node: Initial and virgin, Next: Memory dumps, Up: Three programs + +3.5.1 Initial and virgin +------------------------ + +The TeX, Metafont, and MetaPost programs each have two main variants, +called "initial" and "virgin". As of Web2c 7, one executable suffices +for both variants, and in fact, the `ini...' executables are no longer +created. + + The initial form is enabled if: + 1. the `-ini' option was specified; or + + 2. the program name is `initex' resp. `inimf' resp. `inimpost' + (these variants are no longer typically installed); or + + 3. the first line of the main input file is `%&ini'; + otherwise, the virgin form is used. + + The "virgin" form is the one generally invoked for production use. +The first thing it does is read a memory dump (*note Determining the +memory dump to use::), and then proceeds on with the main job. + + The "initial" form is generally used only to create memory dumps +(see the next section). It starts up more slowly than the virgin form, +because it must do lengthy initializations that are encapsulated in the +memory dump file. + + +File: web2c.info, Node: Memory dumps, Next: Editor invocation, Prev: Initial and virgin, Up: Three programs + +3.5.2 Memory dumps +------------------ + +In typical use, TeX, Metafont, and MetaPost require a large number of +macros to be predefined; therefore, they support "memory dump" files, +which can be read much more efficiently than ordinary source code. + +* Menu: + +* Creating memory dumps:: +* Determining the memory dump to use:: +* Hardware and memory dumps:: + + +File: web2c.info, Node: Creating memory dumps, Next: Determining the memory dump to use, Up: Memory dumps + +3.5.2.1 Creating memory dumps +............................. + +The programs all create memory dumps in slightly idiosyncratic (thought +substantially similar) way, so we describe the details in separate +sections (references below). The basic idea is to run the initial +version of the program (*note Initial and virgin::), read the source +file to define the macros, and then execute the `\dump' primitive. + + Also, each program uses a different filename extension for its memory +dumps, since although they are completely analogous they are not +interchangeable (TeX cannot read a Metafont memory dump, for example). + + Here is a list of filename extensions with references to examples of +creating memory dumps: + +TeX + (`.fmt') *Note Initial TeX: Initial TeX. + +Metafont + (`.base') *Note Initial Metafont::. + +MetaPost + (`.mem') *Note Initial MetaPost::. + + When making memory dumps, the programs read environment variables and +configuration files for path searching and other values as usual. If +you are making a new installation and have environment variables +pointing to an old one, for example, you will probably run into +difficulties. + + +File: web2c.info, Node: Determining the memory dump to use, Next: Hardware and memory dumps, Prev: Creating memory dumps, Up: Memory dumps + +3.5.2.2 Determining the memory dump to use +.......................................... + +The virgin form (*note Initial and virgin::) of each program always +reads a memory dump before processing normal source input. All three +programs determine the memory dump to use in the same way: + + 1. If the first non-option command-line argument begins with `&', the + program uses the remainder of that argument as the memory dump + name. For example, running `tex \&super' reads `super.fmt'. (The + backslash protects the `&' against interpretation by the shell.) + + 2. If the `-fmt' resp. `-base' resp. `-mem' option is specified, its + value is used. + + 3. If the `-progname' option is specified, its value is used. + + 4. If the first line of the main input file (which must be specified + on the command line, not in response to `**') is `%&DUMP', and + DUMP is an existing memory dump of the appropriate type, DUMP is + used. + + The first line of the main input file can also specify which + character translation file is to be used: + `%&-translate-file=TCXFILE' (*note TCX files::). + + These two roles can be combined: `%&DUMP -translate-file=TCXFILE'. + If this is done, the name of the dump must be given first. + + 5.

(This is a feature +of the Web2c implementation, and is not true of all TeX +implementations.) If you specify `--disable-dump-share' to +`configure', however, memory dumps will be endian-dependent. + + The reason to do this is speed. To achieve endian-independence, the +reading of memory dumps on LittleEndian architectures, such as PC's and +DEC architectures, is somewhat slowed (all the multibyte values have to +be swapped). Usually, this is not noticeable, and the advantage of +being able to share memory dumps across all platforms at a site far +outweighs the speed loss. But if you're installing Web2c for use on +LittleEndian machines only, perhaps on a PC being used only by you, you +may wish to get maximum speed. + + TeXnically, even without `--disable-dump-share', sharing of `.fmt' +files cannot be guaranteed to work. Floating-point values are always +written in native format, and hence will generally not be readable +across platforms. Fortunately, TeX uses floating point only to +represent glue ratios, and all common formats (plain, LaTeX, AMSTeX, +...) do not do any glue setting at `.fmt'-creation time. Metafont and +MetaPost do not use floating point in any dumped value at all. + + Incidentally, different memory dump files will never compare equal +byte-for-byte, because the program always dumps the current date and +time. So don't be alarmed by just a few bytes difference. + + If you don't know what endianness your machine is, and you're +curious, here is a little C program to tell you. (The `configure' script +contains a similar program.) This is from the book `C: A Reference +Manual', by Samuel P. Harbison and Guy L. Steele Jr. (*note +References::). + + main () + { + /* Are we little or big endian? From Harbison&Steele. */ + union + { + long l; + char c[sizeof (long)]; + } u; + u.l = 1; + if (u.c[0] == 1) + printf ("LittleEndian\n"); + else if (u.c[sizeof (long) - 1] == 1) + printf ("BigEndian\n"); + else + printf ("unknownEndian"); + + exit (u.c[sizeof (long) - 1] == 1); + } + + +File: web2c.info, Node: Editor invocation, Next: \input filenames, Prev: Memory dumps, Up: Three programs + +3.5.3 Editor invocation +----------------------- + +TeX, Metafont, and MetaPost all (by default) stop and ask for user +intervention at an error. If the user responds with `e' or `E', the +program invokes an editor. + + Specifying `--with-editor=CMD' to `configure' sets the default +editor command string to CMD. The environment variables/configuration +values `TEXEDIT', `MFEDIT', and `MPEDIT' (respectively) override this. +If `--with-editor' is not specified, the default is `vi +%d %s'. + + In this string, `%d' is replaced by the line number of the error, +and `%s' is replaced by the name of the current input file. + + +File: web2c.info, Node: \input filenames, Prev: Editor invocation, Up: Three programs + +3.5.4 `\input' filenames +------------------------ + +TeX, Metafont, and MetaPost source programs can all read other source +files with the `\input' (TeX) and `input' (MF and MP) primitives: + \input NAME % in TeX + + The file NAME can always be terminated with whitespace; for Metafont +and MetaPost, the statement terminator `;' also works. (LaTeX and +other macro packages provide other interfaces to `\input' that allow +different notation; here we are concerned only with the primitive +operation.) + + As of Web2c version 7.5.3, double-quote characters can be used to +include spaces or other special cases. In typical use, the `"' +characters surround the entire filename: + \input "filename with spaces" + + Technically, the quote characters can be used inside the name, and +can enclose any characters, as in: + \input filename" "with" "spaces + + One more point. In LaTeX, the quotes are needed inside the braces, +thus + \input{a b} % fails + \input{"a b"} % ok + + This quoting mechanism comes into play _after_ TeX has tokenized and +expanded the input. So, multiple spaces and tabs may be seen as a +single space, active characters such as `~' are expanded first, and so +on. (See below.) + + On the other hand, various C library routines and Unix itself use +the null byte (character code zero, ASCII NUL) to terminate strings. So +filenames in Web2c cannot contain nulls, even though TeX itself does +not treat NUL specially. In addition, some older Unix variants do not +allow eight-bit characters (codes 128-255) in filenames. + + For maximal portability of your document across systems, use only the +characters `a'-`z', `0'-`9', and `.', and restrict your filenames to at +most eight characters (not including the extension), and at most a +three-character extension. Do not use anything but simple filenames, +since directory separators vary among systems; instead, add the +necessary directories to the appropriate search path. + + Finally, the present Web2c implementation does `~' and `$' expansion +on NAME, unlike Knuth's original implementation and older versions of +Web2c. Thus: + \input ~jsmith/$foo.bar + will dereference the environment variable or Kpathsea config file +value `foo' and read that file extended with `.bar' in user `jsmith''s +home directory. You can also use braces, as in `${foo}bar', if you +want to follow the variable name with a letter, numeral, or `_'. + + (So another way to get a program to read a filename containing +whitespace is to define an environment variable and dereference it.) + + In all the common TeX formats (plain TeX, LaTeX, AMSTeX), the +characters `~' and `$' have special category codes, so to actually use +these in a document you have to change their catcodes or use `\string'. +(The result is unportable anyway, see the suggestions above.)

This approach has both +considerable disadvantages and considerable advantages. For a complete +description of the TeX language, see `The TeXbook' (*note +References::).

To see all the relevant paths, set +the environment variable `KPATHSEA_DEBUG' to `-1' before running the +program. + + After TEXNAME is read, TeX processes any remaining TEX-COMMANDS on +the command line as regular TeX input. Also, if the first non-option +argument begins with a TeX escape character (usually `\'), TeX +processes all non-option command-line arguments as a line of regular +TeX input. + + If no arguments or options are specified, TeX prompts for an input +file name with `**'. + + TeX writes the main DVI output to the file `BASETEXNAME.dvi', where +BASETEXNAME is the basename of TEXNAME, or `texput' if no input file +was specified. A DVI file is a device-independent binary +representation of your TeX document. The idea is that after running +TeX, you translate the DVI file using a separate program to the +commands for a particular output device, such as a PostScript printer +(*note Introduction: (dvips)Top.) or an X Window System display (see +xdvi(1)). + + TeX also reads TFM files for any fonts you load in your document with +the `\font' primitive. By default, it runs an external program named +`mktextfm' to create any nonexistent TFM files. You can disable this +at configure-time or runtime (*note mktex configuration: +(kpathsea)mktex configuration.). This is enabled mostly for the sake +of the EC fonts, which can be generated at any size. + + TeX can write output files, via the `\openout' primitive; this opens +a security hole vulnerable to Trojan horse attack: an unwitting user +could run a TeX program that overwrites, say, `~/.rhosts'. (MetaPost +has a `write' primitive with similar implications). To alleviate this, +there is a configuration variable `openout_any', which selects one of +three levels of security. When it is set to `a' (for "any"), no +restrictions are imposed. When it is set to `r' (for "restricted"), +filenames beginning with `.' are disallowed (except `.tex' because +LaTeX needs it). When it is set to `p' (for "paranoid") additional +restrictions are imposed: an absolute filename must refer to a file in +(a subdirectory) of `TEXMFOUTPUT', and any attempt to go up a directory +level is forbidden (that is, paths may not contain a `..' component). +The paranoid setting is the default. (For backwards compatibility, `y' +and `1' are synonyms of `a', while `n' and `0' are synonyms for `r'.) + + In any case, all `\openout' filenames are recorded in the log file, +except those opened on the first line of input, which is processed when +the log file has not yet been opened. (If you as a TeX administrator +wish to implement more stringent rules on `\openout', modifying the +function `openoutnameok' in `web2c/lib/texmfmp.c' is intended to +suffice.) + + The program accepts the following options, as well as the standard +`-help' and `-version' (*note Common options::): +`-enc' +`-[no]-file-line-error' +`-fmt=FMTNAME' +`-halt-on-error' +`-ini' +`-interaction=STRING' +`-ipc' +`-ipc-start' +`-jobname=STRING' +`-kpathsea-debug=NUMBER' +`-[no]parse-first-line' +`-output-directory' +`-progname=STRING' +`-recorder' +`-translate-file=TCXFILE' +`-8bit' + These options are common to TeX, Metafont, and MetaPost. *Note + Common options::. + +`-enc' + Enable encTeX extensions, such as `\mubyte'.

(For backwards compatibility, `y' + and `1' are accepted as synonyms of `t'). It is disabled by + default to avoid security problems. When enabled, the + SHELL-COMMAND string (which first undergoes the usual TeX + expansions, just as in `\special') is passed to the command shell + (via the C library function `system'). The output of + SHELL-COMMAND is not diverted anywhere, so it will not appear in + the log file. The system call either happens at `\output' time or + right away, according to the absence or presence of the + `\immediate' prefix, as usual for `\write'. (If you as a TeX + administrator wish to implement more stringent rules on what can + be executed, you will need to modify `tex.ch'.) + +`-src-specials' +`-src-specials=STRING' + This option makes TeX output specific source information using + `\special' commands in the DVI file. These `\special' track the + current file name and line number. + + Using the first form of this option, the `\special' commands are + inserted automatically. + + In the second form of the option, STRING is a comma separated list + of the following values: `cr', `display', `hbox', `math', `par', + `parend', `vbox'. You can use this list to specify where you want + TeX to output such commands. For example, `-src-specials=cr,math' + will output source information every line and every math formula. + + These commands can be used with the appropriate DVI viewer and + text editor to switch from the current position in the editor to + the same position in the viewer and back from the viewer to the + editor. + + This option works by inserting `\special' commands into the token + stream, and thus in principle these additional tokens can be + recovered or seen by the tricky-enough macros. If you run across + a case, let us know, because this counts as a bug. However, such + bugs are very hard to fix, requiring significant changes to TeX, + so please don't count on it. + + Redefining `\special' will not affect the functioning of this + option.

These are restricted to substitutions of an accented +character glyph, which need not be defined in the current font, by its +appropriate `\accent' construction using a base and accent character +glyph, which do have to exist in the current font. This substitution +is automatically done behind the scenes, if necessary, and thus MLTeX +additionally supports hyphenation of words containing an accented +character glyph for fonts missing this glyph (e.g., Computer Modern). +Standard TeX suppresses hyphenation in this case. + + MLTeX works at `.fmt'-creation time: the basic idea is to specify +the `-mltex' option to TeX when you `\dump' a format. Then, when you +subsequently invoke TeX and read that `.fmt' file, the MLTeX features +described below will be enabled. + + Generally, you use special macro files to create an MLTeX `.fmt' +file. + + The sections below describe the two new primitives that MLTeX +defines. Aside from these, MLTeX is completely compatible with +standard TeX. + +* Menu: + +* \charsubdef:: Character substitution definitions. +* \tracingcharsubdef:: Tracing substitutions. + + +File: web2c.info, Node: \charsubdef, Next: \tracingcharsubdef, Up: MLTeX + +4.4.1.1 `\charsubdef': Character substitutions +.............................................. + +The most important primitive MLTeX adds is `\charsubdef', used in a way +reminiscent of `\chardef': + \charsubdef COMPOSITE [=] ACCENT BASE + + Each of COMPOSITE, ACCENT, and BASE are font glyph numbers, +expressed in the usual TeX syntax: `\e symbolically, '145 for octal, +"65 for hex, 101 for decimal. + + MLTeX's `\charsubdef' declares how to construct an accented +character glyph (not necessarily existing in the current font) using two +character glyphs (that do exist). Thus it defines whether a character +glyph code, either typed as a single character or using the `\char' +primitive, will be mapped to a font glyph or to an `\accent' glyph +construction. + + For example, if you assume glyph code 138 (decimal) for an +e-circumflex and you are using the Computer Modern fonts, which have +the circumflex accent in position 18 and lowercase `e' in the usual +ASCII position 101 decimal, you would use `\charsubdef' as follows: + + \charsubdef 138 = 18 101 + + For the plain TeX format to make use of this substitution, you have +to redefine the circumflex accent macro `\^' in such a way that if its +argument is character `e' the expansion `\char138 ' is used instead of +`\accent18 e'. Similar `\charsubdef' declaration and macro +redefinitions have to be done for all other accented characters. + + To disable a previous `\charsubdef C', redefine C as a pair of +zeros. For example: + \charsubdef '321 = 0 0 % disable N tilde + (Octal '321 is the ISO Latin-1 value for the Spanish N tilde.) + + `\charsubdef' commands should only be given once. Although in +principle you can use `\charsubdef' at any time, the result is +unspecified. If `\charsubdef' declarations are changed, usually either +incorrect character dimensions will be used or MLTeX will output +missing character warnings. (The substitution of a `\charsubdef' is +used by TeX when appending the character node to the current horizontal +list, to compute the width of a horizontal box when the box gets +packed, and when building the `\accent' construction at +`\shipout'-time. In summary, the substitution is accessed often, so +changing it is not desirable, nor generally useful.) + + +File: web2c.info, Node: \tracingcharsubdef, Prev: \charsubdef, Up: MLTeX + +4.4.1.2 `\tracingcharsubdef': Substitution diagnostics +...................................................... + +To help diagnose problems with `\charsubdef', MLTeX provides a new +primitive parameter, `\tracingcharsubdef'. If positive, every use of +`\charsubdef' will be reported. This can help track down when a +character is redefined. + + In addition, if the TeX parameter `\tracinglostchars' is 100 or +more, the character substitutions actually performed at `\shipout'-time +will be recorded. + + +File: web2c.info, Node: TCX files, Prev: patgen invocation, Up: Languages and hyphenation + +4.4.2 TCX files: Character translations +--------------------------------------- + +TCX (TeX character translation) files help TeX support direct input of +8-bit international characters if fonts containing those characters are +being used. Specifically, they map an input (keyboard) character code +to the internal TeX character code (a superset of ASCII). + + Of the various proposals for handling more than one input encoding, +TCX files were chosen because they follow Knuth's original ideas for +the use of the `xchr' and `xord' tables. He ventured that these would +be changed in the WEB source in order to adjust the actual version to a +given environment. It turns out, however, that recompiling the WEB +sources is not as simple a task as Knuth may have imagined; therefore, +TCX files, providing the possibility of changing of the conversion +tables on on-the-fly, have been implemented instead. + + This approach limits the portability of TeX documents, as some +implementations do not support it (or use a different method for +input-internal reencoding). It may also be problematic to determine +the encoding to use for a TeX document of unknown provenance; in the +worst case, failure to do so correctly may result in subtle errors in +the typeset output. But we feel the benefits outweigh these +disadvantages. + + This is entirely independent of the MLTeX extension (*note MLTeX::): +whereas a TCX file defines how an input keyboard character is mapped to +TeX's internal code, MLTeX defines substitutions for a non-existing +character glyph in a font with a `\accent' construction made out of two +separate character glyphs. TCX files involve no new primitives; it is +not possible to specify that an input (keyboard) character maps to more +than one character. + + Information on specifying TCX files: + + * The best way to specify a TCX file is to list it explicitly in the + first line of the main document: + %& -translate-file=TCXFILE + + * You can also specify a TCX file to be used on a particular TeX run + with the command-line option `-translate-file=TCXFILE'. + + * TCX files are searched for along the `WEB2C' path. + + * Initial TeX (*note Initial TeX: Initial TeX.) ignores TCX files. + + The Web2c distribution comes with a number of TCX files. Two +important ones are `il1-t1.tcx' and `il2-t1.tcx', which support ISO +Latin 1 and ISO Latin 2, respectively, with Cork-encoded fonts (a.k.a. +the LaTeX T1 encoding). TCX files for Czech, Polish, and Slovak are +also provided. + + One other notable TCX file is `empty.tcx', which is, well, empty. +Its purpose is to reset Web2C's behavior to the default (only visible +ASCII being printable, as described below) when a format was dumped +with another TCX being active--which is in fact the case for everything +but plain TeX in the TeX Live and other distributions. Thus: + + latex somefile8.tex + => terminal etc. output with 8-bit chars + latex --translate-file=empty.tcx somefile8.tex + => terminal etc. output with ^^ notation + + Syntax of TCX files: + 1. Line-oriented. Blank lines are ignored. + + 2. Whitespace is ignored except as a separator. + + 3. Comments start with `%' and continue to the end of the line. + + 4. Otherwise, a line consists of one or two character codes, + optionally followed by 0 or 1. The last number indicates whether + DEST is considered printable. + SRC [DEST [PRNT]] + + 5. Each character code may be specified in octal with a leading `0', + hexadecimal with a leading `0x', or decimal otherwise. Values must + be between 0 and 255, inclusive (decimal). + + 6. If the DEST code is not specified, it is taken to be the same as + SRC. + + 7. If the same SRC code is specified more than once, it is the last + definition that counts. + + Finally, here's what happens: when TeX sees an input character with +code SRC, it 1) changes SRC to DEST; and 2) makes the DEST code +"printable", i.e., printed as-is in diagnostics and the log file rather +than in `^^' notation. + + By default, no characters are translated, and character codes +between 32 and 126 inclusive (decimal) are printable. + + Specifying translations for the printable ASCII characters (codes +32-127) will yield unpredictable results. Additionally you shouldn't +make the following characters printable: `^^I' (TAB), `^^J' (line +feed), `^^M' (carriage return), and `^^?' (delete), since TeX uses them +in various ways. + + Thus, the idea is to specify the input (keyboard) character code for +SRC, and the output (font) character code for DEST. + + By default, only the printable ASCII characters are considered +printable by TeX. If you specify the `-8bit' option, all characters are +considered printable by default. If you specify both the `-8bit' +option and a TCX file, then the TCX can set specific characters to be +non-printable. + + Both the specified TCX encoding and whether characters are printable +are saved in the dump files (like `tex.fmt').

This approach has both considerable +disadvantages (people unfamiliar with conventional programming +languages will be unlikely to find it usable) and considerable +advantages (you can make your design intentions specific and +parameterizable). For a complete description of the Metafont language, +see `The METAFONTbook' (*note References::). + +* Menu: + +* mf invocation:: Invoking Metafont. +* Initial Metafont:: Making bases. +* Modes:: Device definitions for Metafont. +* Online Metafont graphics:: Seeing MF output online. +* gftodvi invocation:: Making proofsheets for fonts. +* mft invocation:: Prettyprinting Metafont sources. + + +File: web2c.info, Node: mf invocation, Next: Initial Metafont, Up: Metafont + +5.1 `mf' invocation +=================== + +Metafont (usually invoked as `mf') reads character definitions +specified in the Metafont programming language, and outputs the +corresponding font. This section merely describes the options available +in the Web2c implementation. For a complete description of the Metafont +language, see `The Metafontbook' (*note References::). + + Metafont processes its command line and determines its memory dump +(base) file in a way exactly analogous to MetaPost and TeX (*note tex +invocation::, and *note Memory dumps::). Synopses: + + mf [OPTION]... [MFNAME[.mf]] [MF-COMMANDS] + mf [OPTION]... \FIRST-LINE + mf [OPTION]... &BASE ARGS + + Most commonly, a Metafont invocation looks like this: + mf '\mode:=MODE; mag:=MAGNIFICATION; input MFNAME' + (The single quotes avoid unwanted interpretation by the shell.) + + Metafont searches the usual places for the main input file MFNAME +(*note Supported file formats: (kpathsea)Supported file formats.), +extending MFNAME with `.mf' if necessary. To see all the relevant +paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before +running the program. By default, Metafont runs an external program +named `mktexmf' to create any nonexistent Metafont source files you +input. You can disable this at configure-time or runtime (*note mktex +configuration: (kpathsea)mktex configuration.). This is mostly for the +sake of the EC fonts, which can be generated at any size. + + Metafont writes the main GF output to the file `BASEMFNAME.NNNgf', +where NNN is the font resolution in pixels per inch, and BASEMFNAME is +the basename of MFNAME, or `mfput' if no input file was specified. A +GF file contains bitmaps of the actual character shapes. Usually GF +files are converted immediately to PK files with GFtoPK (*note gftopk +invocation::), since PK files contain equivalent information, but are +more compact. (Metafont output in GF format rather than PK for only +historical reasons.) + + Metafont also usually writes a metric file in TFM format to +`BASEMFNAME.tfm'. A TFM file contains character dimensions, kerns, and +ligatures, and spacing parameters. TeX reads only this .tfm file, not +the GF file. + + The MODE in the example command above is a name referring to a +device definition (*note Modes::); for example, `localfont' or +`ljfour'. These device definitions must generally be precompiled into +the base file. If you leave this out, the default is `proof' mode, as +stated in `The Metafontbook', in which Metafont outputs at a resolution +of 2602dpi; this is usually not what you want. The remedy is simply to +assign a different mode--`localfont', for example. + + The MAGNIFICATION assignment in the example command above is a +magnification factor; for example, if the device is 600dpi and you +specify `mag:=2', Metafont will produce output at 1200dpi. Very often, +the MAGNIFICATION is an expression such as `magstep(.5)', corresponding +to a TeX "magstep", which are factors of 1.2 * sqrt(2). + + After running Metafont, you can use the font in a TeX document as +usual. For example: + \font\myfont = newfont + \myfont Now I am typesetting in my new font (minimum hamburgers). + + The program accepts the following options, as well as the standard +`-help' and `-version' (*note Common options::): +`-[no]-file-line-error' +`-fmt=FMTNAME' +`-halt-on-error' +`-ini' +`-interaction=STRING' +`-jobname=STRING' +`-kpathsea-debug=NUMBER' +`-[no]parse-first-line' +`-output-directory' +`-progname=STRING' +`-recorder' +`-translate-file=TCXFILE' +`-8bit' + These options are common to TeX, Metafont, and MetaPost. *Note + Common options::. + +`-mktex=FILETYPE' +`-no-mktex=FILETYPE' + Turn on or off the `mktex' script associated with FILETYPE.

In past releases, a separate program `inimf' was installed +to invoke the initial form, but this is no longer the case. + + For a list of options and other information, see *Note mf +invocation::. + + The only memory dump file commonly used with Metafont is the default +`plain.base', also known as `mf.base' (again, *note Memory dumps::). +It is created by default during installation, but you can also do so by +hand if necessary (e.g., if a Metafont update is issued): + mf -ini '\input plain; input modes; dump' + (The quotes prevent interpretation of the backslashes from the +shell.) Then install the resulting `plain.base' in `$(basedir)' +(`/usr/local/share/texmf/web2c' by default), and link `mf.base' to it. + + For an explanation of the additional `modes.mf' file, see *Note +Modes::. This file has no counterpart in TeX or MetaPost. + + In the past, it was sometimes useful to create a base file +`cmmf.base' (a.k.a. `cm.base'), with the Computer Modern macros also +included in the base file. Nowadays, however, the additional time +required to read `cmbase.mf' is exceedingly small, usually not enough +to be worth the administrative hassle of updating the `cmmf.base' file +when you install a new version of `modes.mf'. People actually working +on a typeface may still find it worthwhile to create their own base +file, of course. + + +File: web2c.info, Node: Modes, Next: Online Metafont graphics, Prev: Initial Metafont, Up: Metafont + +5.3 Modes: Device definitions for Metafont +========================================== + +Running Metafont and creating Metafont base files requires information +that TeX and MetaPost do not: "mode" definitions which specify device +characteristics, so Metafont can properly rasterize the shapes. + + When making a base file, a file containing modes for +locally-available devices should be input after `plain.mf'. One +commonly used file is `ftp://ftp.tug.org/tex/modes.mf'; it includes all +known definitions. + + If, however, for some reason you have decreased the memory available +in your Metafont, you may need to copy `modes.mf' and remove the +definitions irrelevant to you (probably most of them) instead of using +it directly. (Or, if you're a Metafont hacker, maybe you can suggest a +way to redefine `mode_def' and/or `mode_setup'; right now, the amount +of memory used is approximately four times the total length of the +`mode_def' names, and that's a lot.) + + If you have a device not included in `modes.mf', please see comments +in that file for how to create the new definition, and please send the +definition to <tex-fonts@mail.tug.org> to get it included in the next +release of `modes.mf'. + + Usually, when you run Metafont you must supply the name of a mode +that was dumped in the base file. But you can also define the mode +characteristics dynamically, by invoking Metafont with an assignment to +`smode' instead of `mode', like this: + mf '\smode:="newmode.mf"; mag:=MAGNIFICATION; input MFNAME' + This is most useful when you are working on the definition of a new +mode. + + The MAGNIFICATION and MFNAME arguments are explained in *Note mf +invocation::.

Synopsis: + + mft [OPTION]... MFNAME[.mf] + + MFT searches the usual places for MFNAME (*note Supported file +formats: (kpathsea)Supported file formats.). To see all the relevant +paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before +running the program. The output goes to the basename of MFNAME extended +with `.tex', e.g., `mft /wherever/foo.mf' creates `./foo.tex'. + + Line breaks in the input are carried over into the output; moreover, +blank spaces at the beginning of a line are converted to quads of +indentation in the output. Thus, you have full control over the +indentation and line breaks. Each line of input is translated +independently of the others. + + Further control is allowed via Metafont comments: + * Metafont comments following a single `%' should be valid TeX + input. But Metafont material can be included within vertical bars + in a comment; this will be translated by MFT as if it were regular + Metafont code. For example, a comment like `% |x2r| is the tip of + the bowl' will be translated into the TeX `% $x_{2r}$ is the ...', + i.e., the `x2r' is treated as an identifier. + + * `%%' indicates that the remainder of an input line should be copied + verbatim to the output. This is typically used to introduce + additional TeX material at the beginning or an MFT job, e.g. code + to modify the standard layout or the formatting macros defined in + `mftmac.tex', or to add a line saying `%%\bye' at the end of the + job. (MFT doesn't add this automatically in order to allow + processing several files produces by MFT in the same TeX job.) + + * `%%% TOKEN1 OTHER-TOKENS' introduces a change in MFT's formatting + rules; all the OTHER-TOKENS will henceforth be translated + according to the current conventions for TOKEN1. The tokens must + be symbolic (i.e., not numeric or string tokens). For example, the + input line + %%% addto fill draw filldraw + says to format the `fill', `draw', and `filldraw' operations of + plain Metafont just like the primitive token `addto', i.e., in + boldface type. Without such reformatting commands, MFT would + treat `fill' like an ordinary tag or variable name. In fact, you + need a `%%%' command even to get parentheses to act like + delimiters. + + * `%%%%' introduces an MFT comment, i.e., MFT ignores the remainder + of such a line. + + * Five or more `%' signs should not be used. + + (The above description was edited from `mft.web', written by +D.E.

Synopses: + + mpost [OPTION]...

To see all the relevant +paths, set the environment variable `KPATHSEA_DEBUG' to `-1' before +running the program. + + MetaPost writes its PostScript output to a series of files +`BASEMPNAME.NNN' (or perhaps `BASEMPNAME.ps', very occasionally +`BASEMPNAME.tfm'), where NNN are the figure numbers specified in the +input, typically to the `beginfig' macro, and BASEMPNAME is the +basename of MPNAME, or `mpout' if no input file was specified. +MetaPost uses the `.ps' extension when the figure number is out of +range, e.g., if you say `beginfig(-1)'. + + You can use the output files as figures in a TeX document just as +with any other PostScript figures. For example, with this TeX command: + \special{psfile="FILENAME"} + or by using `epsf.tex' (*note EPSF macros: (dvips)EPSF macros.). + + The MetaPost construct + btex ... TEX-INPUT ... etex + calls MakeMPX to generate a MPX file containing a MetaPost picture +expression corresponding to TEX-INPUT (*note makempx invocation::). + + The construct + verbatimtex ... TEX-INPUT ... etex + simply passes the TEX-INPUT through to MakeMPX and thus to TeX. For +example, if you are using LaTeX, your MetaPost input file must start +with a `verbatimtex' block that gives the necessary `\documentclass' +(or `\documentstyle') `\begin{document}' command. You will also need +to set the enviroment variable `TEX' to `latex' (*note makempx +invocation::). + + TEX-INPUT need not be specifically TeX input; it could also be +Troff. In that case, you will need the `-m pictures' Troff macro +package (unfortunately absent from many Troff implementations), or an +equivalent such as the `-m pspic' macros from GNU groff described in +grops(1). + + Other typesetters can be supported with no change to MetaPost itself; +only MakeMPX needs to be updated. + + Naturally, you must use fonts that are supported by the typesetter; +specifically, you'll probably want to use standard PostScript fonts with +Troff. And only the TeX system understands Computer Modern or other +Metafont fonts; you can also use PostScript fonts with TeX, of course. + + MetaPost-generated PostScript figures which do use Computer Modern +fonts for labels cannot be directly previewed or printed. Instead, you +must include them in a TeX document and run the resulting DVI file +through Dvips to arrange for the downloading of the required fonts +(*note Fonts in figures: (dvips)Fonts in figures.).

However, if the file MPXFILE already exists, and is +newer than MPFILE, then nothing is done (presumably the file is +up-to-date). + + Otherwise: + 1. MPto is run to extract the label text from the MetaPost source + file MPFILE (*note mpto invocation::). + + 2. The typesetting program itself is run, either TeX or Troff (see + below). If TeX, and the file named by the `MPTEXPRE' environment + variable exists (`mptexpre.tex' by default), that file is + prepended to the input from the MetaPost file. + + 3. The typesetter output (a DVI file in the case of TeX, Ditroff + output for Troff) is translated back to MetaPost, by DVItoMP + (*note dvitomp invocation::) or DMP (*note dmp invocation::) + respectively. + + If any of the above steps fail, for example if there was a +typesetting mistake in the original MPFILE, output may be left in files +named `mpxerr.{log,tex,dvi}' (TeX) or `mpxerr{,.t}' (Troff), so you can +diagnose the problem. + + The `-troff' option to MPto selects the Troff commands, rather than +TeX. MetaPost supplies this automatically if the `-T' or `-troff' +option was specified to MetaPost. + + The MPX file created by MakeMPX is a sequence of MetaPost picture +expressions, one for every label in the original MetaPost input file. + + The names of the commands run by MakeMPX, and the directory added to +the shell search `PATH' for the commands' location, are overridden by +environment variables. Here is a list: + +`MAKEMPX_BINDIR' + The directory added to the `PATH'. Default is the `$(bindir)' + Make directory, which in turn is set from the configure-time + `--bindir', `--exec-prefix' and `--prefix' options; if nothing + else is specified, the default is file `/usr/local'. + +`NEWER' + The command run to determine if MPXFILE is out of date with respect + to MPFILE; default is `newer'. + +`MPTOTEX' + The command run to extract MetaPost labels in TeX format; default + is `mpto -tex'. + +`MPTOTR' + Likewise, for Troff; default is `mpto -troff'. + +`DVITOMP' + The command run to convert TeX output back to MetaPost; default is + `dvitomp'. + +`DMP' + Likewise, for Troff; default is `dmp'. + +`TEX' + The command run to typeset the labels in TeX; default is `tex'. + If you use LaTeX, set this to `latex', and supply an appropriate + `verbatimtex' header in the MP source (*note mpost invocation::). + +`TROFF' + Likewise, for Troff; default is `'eqn -d\$\$ | troff -Tpost''. You + may need to replace `-Tpost' by `-TTERM', where TERM is the + PostScript device name for your Troff implementation, e.g., `ps' + or `psc'; see troff(1). + + If you change this, you will also need to set the `TRFONTS' + environment variable or configuration value to point to the + appropriate font directory, traditionally `/usr/lib/font/devTERM'. + + + +File: web2c.info, Node: dvitomp invocation, Next: dmp invocation, Prev: makempx invocation, Up: MetaPost + +6.4 DVItoMP: DVI to MPX conversion +================================== + +DVItoMP converts DVI files into low-level MetaPost commands in a +so-called MPX file.

This program is +generally invoked by MakeMPX (*note makempx invocation::). Synopsis: + + dmp [DITROFF-FILE [MPXFILE]] + +If DITROFF-FILE is not specified, input comes from standard input; and +if MPXFILE is not specified, output goes to standard output. + + DMP was written to process the output of a Troff pipeline fed the +output of `mpto -troff' (*note mpto invocation::). DMP understands all +the `DC' graphics functions that `dpost' does, but it ignores `x X' +device control functions such as `x X SetColor:...', `x X BeginPath:', +and `x X DrawPath:...'. + + The available font names are defined in the support file +`trfonts.map', which DMP looks for along the `MPSUPPORT' path. + + Another support file `trchars.adj', also looked for along the +`MPSUPPORT' path, contains a character adjustment table which should +reflect the shift amounts found in the standard PostScript prologue for +Troff and dpost found in the `TRFONTS' directory. Such an adjustment +table is unnecessary for some Troff implementations, in which case +`trchars.adj' should be replaced by an empty file--but it must still +exist. + + DMP was written for one particular Troff implementation, and it +unfortunately has many built-in assumptions about the output and fonts +file formats used by Troff, which may not be satisfied in other +environments. In particular, GNU groff uses some extensions in its file +formats described in groff_font(5) and groff_out(5) which make its +output completely unusable for DMP. On the other hand, the Troff +version found in Sun Solaris 2.x, and perhaps other systems derived from +System V R4, works fine with the default settings. + + If you run into trouble and want to adapt DMP to other systems, you +might have to try the following (this is primarily for hackers): + + * If DMP complains about a missing font table (e.g., `Cannot find + TR'), your Troff may not support the device `post'. + + Check troff(1) for the devices supported by your Troff and set the + `TROFF' environment variable appropriately (see above). Also, + locate the appropriate font directory and set the `TRFONTS' + variable as needed. + + * If DMP complains about a missing font description file (e.g., `Font + TR was not in map file'), your version of Troff may be using + internal font names different from those in the distributed + `trfonts.map'; e.g., TR and TI instead of R and I for Times-Roman + and Times-Italic. + + In this case, you may have to adapt `trfonts.map' and perhaps also + `trchars.adj' in the MetaPost support directory + (`texmf/metapost/support' by default). + + * If DMP still complains that it cannot parse the font description + files or the Troff output (e.g., `TR has a bad line in its + description file', you are probably out of luck and have to hack + the DMP program (in `web2c/mpware/dmp.c'). + + Such problems may be caused by subtle differences in the file + formats, such as use of tabs vs. spaces as field separators or + decimal vs. octal vs. hex format for font metric data. + + A reasonably good description of the expected Troff file formats + can be found in AT&T technical report CSTR-54 (`Troff User's + Manual', Revised 1992). Documentation on the subtle differences + in other Troff implementation is harder to find except for GNU + groff, where it's all documented in the above-mentioned + groff_font(5) and groff_out(5). + + Any contributions to improve the portability of DMP or to make it + work with GNU groff are welcome, of course. + + + (Some of the above description was edited from the `dmp.c' source +file, written by John Hobby.) + + The only options are `--help' and `--version' (*note Common +options::). + + +File: web2c.info, Node: mpto invocation, Next: newer invocation, Prev: dmp invocation, Up: MetaPost + +6.6 MPto: Extract labels from MetaPost input +============================================ + +MPto extracts the labels from a MetaPost input file; this is the +contents of any `btex...etex' and `verbatimtex...etex' sections.

The font +metric information contained in TFM files is device-independent units is +used by TeX to do typesetting. Unlike the bitmap (raster) fonts +described below, TFM font files contain no information about the shapes +of characters. They describe rectangular areas and combinations +thereof, but not what will eventually be printed in those areas. + + Since TeX does scaling calculations, one TFM file serves for all +magnifications of a given typeface. On the other hand, the best printed +results are obtained when magnified (or reduced fonts) are not produced +geometrically (as done by PostScript, for example) but rather optically, +with each size a separate design (as done with Computer Modern and the +EC fonts, for example); then a separate TFM file is needed for each +size. + + At any rate, TeX produces a DVI (DeVice Independent) file from your +source document. In order to print DVI files on real devices, you need +font files defining digitized character shapes and other data. Then +previewers and printer-driver programs can translate your DVI files into +something usable by your monitor or printer. Bitmap fonts come with +suffixes such as `.600pk' or `.600gf' or `.3000pxl', where the `600' is +the horizontal dots-per-inch resolution at which the font was produced, +and the `pk' or `gf' or `pxl' indicates the font format. Outline fonts +in PostScript Type 1 format have suffixes such as `.pfa' or `.pfb'. + + Fonts in pk (packed) format are in the tightly packed raster format +that is pretty much the standard today. They take up less space than +fonts in the gf (generic font) format that Metafont generates, and far +less space than fonts in pxl format. Fonts in pxl format take up gross +amounts of disk space and permit only 128 characters. They are +obsolete. + + Font files with the `.pl' (property list) suffix are the plain text +(human-readable) analog of the binary `.tfm' files. The TFtoPL and +PLtoTF programs convert between the two formats (*note tftopl +invocation:: and *Note pltotf invocation::). + + Font files with the `.mf' suffix are in Metafont source format. +These are the files used by Metafont to generate rastered fonts for +specific typefaces at specific magnifications for the specific +resolution and type of mapping used by your device. + + The suffix `.vf' identifies "virtual font" files, for which `.vpl' +is the human-readable analog. See *Note vftovp invocation::, and *Note +vptovf invocation::. For further discussion of virtual fonts, see +`CTAN:/doc/virtual-fonts.knuth', `CTAN:/help/virtualfonts.txt', and +*Note Virtual fonts: (dvips)Virtual fonts. + + (This section is based on documentation in the original Unix TeX +distribution by Pierre MacKay and Elizabeth Tachikawa.) + + +File: web2c.info, Node: gftopk invocation, Next: pktogf invocation, Prev: Font file formats, Up: Font utilities + +10.2 GFtoPK: Generic to packed font conversion +============================================== + +GFtoPK converts a generic font (GF) file output by, for example, +Metafont (*note mf invocation::) to a packed font (PK) file.

The property list +file can be converted back to VF and TFM format by the companion +program VFtoVP (see the next section). + + The program accepts the following option, as well as the standard +`-verbose', `-help' and `-version' (*note Common options::): +`-charcode-format=TYPE' + Output character codes in the PL file according to TYPE: either + `octal' or `ascii'. Default is `ascii' for letters and digits, + octal for all other characters. Exception: if the font's coding + scheme starts with `TeX math sy' or `TeX math ex', all character + codes are output in octal. + + In `ascii' format, character codes that correspond to graphic + characters, except for left and right parentheses, are output as a + `C' followed by the single character: `C K', for example. In + octal format, character codes are output as the letter `O' followed + by octal digits, as in `O 113' for `K'. + + `octal' format is useful for symbol and other non-alphabetic fonts, + where using ASCII characters for the character codes is merely + confusing. + + +File: web2c.info, Node: vptovf invocation, Next: Font utilities available elsewhere, Prev: vftovp invocation, Up: Font utilities + +10.9 VPtoVF: Virtual property lists to virtual font +=================================================== + +VPtoVF translates a virtual property list file (as output by VFtoVP, for +example) to virtual font (VF, *note Virtual fonts: (dvips)Virtual +fonts.) and TeX font metric (TFM, *note Metric files: (dvips)Metric +files.) files. It's much easier for both programs and humans to create +the (plain text) property list files and let VPtoVF take care of +creating the binary VF and TFM equivalents than to output them +directly. Synopsis: + + vptovf [OPTION]... VPLFILE[.vpl] [VFFILE[.vf] [TFMFILE[.tfm]]] + + If VFFILE (extended with `.vf' if necessary) is not specified, the +VF output is written to the basename of `VPLFILE.vf'; similarly for +TFMFILE. For example, `vptovf /wherever/ptmr.vpl' creates `./ptmr.vf' +and `./ptmr.tfm'. + + The only options are `-verbose', `-help', and `-version' (*note +Common options::). + + +File: web2c.info, Node: Font utilities available elsewhere, Prev: vptovf invocation, Up: Font utilities + +10.10 Font utilities available elsewhere +======================================== + +The Web2c complement of font utilities merely implements a few basic +conversions. Many other more sophisticated font utilities exist; most +are in `CTAN:/fonts/utilities' (for CTAN info, *note unixtex.ftp: +(kpathsea)unixtex.ftp.). Here are some of the most commonly-requested +items: + + * AFM (Adobe font metric) to TFM conversion: *note Invoking afm2tfm: + (dvips)Invoking afm2tfm, and `CTAN:/fonts/utilities/afmtopl'. + + * BDF (the X bitmap format) conversion: + `ftp://ftp.tug.org/tex/bdf.tar.gz'. + + * Creating fonts using MetaPost: MetaType1. + `ftp://bop.eps.gda.pl/pub/metatype1'. This is used to create the + excellent Latin Modern font family (`CTAN:/fonts/lm'), which + extends Computer Modern to a vast repertoire of scripts. + + * Editing of bitmap fonts: Xbfe from the GNU font utilities mentioned + below; the X BDF-editing programs available from + `ftp://ftp.x.org/R5contrib/xfed.tar.Z' and + `ftp://ftp.x.org/R5contrib/xfedor.tar.Z'; and finally, if your + fonts have only 128 characters, you can use the old `gftopxl', + `pxtoch', and `chtopx' programs from `ftp://ftp.tug.org/tex/web'. + + * Editing of outline fonts: FontForge, `fontforge.sourceforge.net'. + This is a very elaborate program with support for many outline + formats (Type 1, OpenType, TrueType, ...), and many advanced font + editing features. + + * PK bitmaps from PostScript outline fonts: gsftopk from the `xdvi' + distribution. Alternatively, `ps2pk', from + `CTAN:/fonts/utilities/ps2pk'. + + * PostScript Type 1 font format conversion (i.e., between PFA and PFB + formats): `ftp://ftp.tug.org/tex/t1utils.tar.gz'. + + * Scanned image conversion: the (aging) GNU font utilities convert + type specimen images to Metafont, PostScript, etc.: + `http://www.gnu.org/software/fontutils/'. + + * Tracing bitmaps to fitted outlines: Autotrace + (`http://autotrace.sourceforge.net'), Potrace + (`http://potrace.sourceforge.net'). For Metafont fonts, either of + the two programs `mftrace' + (`http://www.xs4all.nl/~hanwen/mftrace') or `textrace' + (`http://textrace.sourceforge.net') make the job easier. + + * Virtual font creation: `CTAN:/fonts/utilities/fontinst'. + + +File: web2c.info, Node: Legalisms, Next: References, Prev: Font utilities, Up: Top + +Appendix A Legalisms +******************** + +In general, each file has its own copyright notice stating the copying +permissions for that file.
