It includes the following +files: + + texdoctk - the program source + texdoctk.dat - the database containing the information about the + accessible documentation files for teTeX-texmf + texdocrc.defaults - the system-wide default specification for viewer + and printer settings + texdoctk.1 - manpage + README.texdoctk - this file +The current version is 0.6.0. + +REQUIREMENTS +The program is written in Perl/Tk; it requires Perl 5 and Perl/Tk 8.x. It is +known to run with Perl 5.004_04 or higher and PerlTk 800.015. +The database file texdoctk.dat is made for the teTeX distribution. +Note that the program is *not* a viewer, but an interface to access a document +with the appropriate viewer. Thus, you need to have appropriate viewers for +the different formats to actually read the files. Documentations are available +as .dvi, .ps, .pdf, .html or plain text; some packages are only documented in +the .sty files. For plain text files (.txt, .sty etc.), texdoctk's own text +viewer can be used (default). If a document format is not known, texdoctk +will by default assume that it is plain text and use the text file viewer; +this behaviour can be switched off in the Settings menu. +If you want to print the documentations, you will need converters to turn +non-PS files into PostScript. Here are some suggestions: +dvi->ps: dvips (is part of teTeX) + http://www.radicaleye.com/dvips.html +pdf->ps: pdf2ps + http://www.cs.wisc.edu/~ghost + Acrobat Reader + http://www.adobe.com +html->ps: html2ps + http://user.it.uu.se/~jan/html2ps.html +plain text->ps: a2ps + http://www-inf.enst.fr/~demaille/a2ps/ +To increase the font size automatically for high-resolution screen, the program +xwininfo is used; texdoctk will work without as well, though. + +INSTALLATION +The program texdoctk can be copied into any directory where programs are stored +on your system, e.g. into /usr/local/bin or, probably more adequate, into +/usr/local/teTeX/bin. It assumes that you have the env command in /usr/bin/ +available to determine the location of the Perl executable; therefore, you may +need to change the first line of the code if this is not the case for your +system or if for some reason your Perl executable is not called "perl"; you +will also have to change the perl call in the sub viewslc as well. +The database file texdoctk.dat and the configuration file texdocrc.defaults +must then be put into a subdirectory of the main texmf directory called +texdoctk. If you want to include information for your local system, +generate a file texdoctk-local.dat. Make sure to run texhash after +installation. See the manpage for more info. +Set the defaults in texdocrc.defaults according to your system; you can +replace the settings which are specified in the shipped file, but do not +uncomment variables for items which are not available or applicable for you, +but just leave the value empty by specifying nothing. +The individual users can define their own preferences by copying the system +texdocrc.defaults to ~/.texdocrc and assign new values to the items to be +changed. They can also establish an additional personal database for packages +they might have installed in their respective $HOME; this database must be +called texdoctk-pers.dat and reside in $HOMETEXMF/texdoctk/. +If you meet the requirements concerning the teTeX distribution, I assume that +the texdoctk.dat file should work without failures; if you have another +distribution or if your texmf/doc tree is somehow modified, it may happen that +a file is not found in spite of the program trying to find it elsewhere. You +will have to edit the file then, but make sure to keep the right format for +the entries: +<package-label>;Short description for listbox (opt. <package-name>);path in doc directory;optional keywords +(without breaking the line!). If the documentation is included in the .sty file +instead of a proper documentation file, the optional keywords should start with +-?- directly after the semicolon, where ? is 0, 1, 2 or 3; these are flags +which indicate in which part of the .sty the instructions are placed. See the +database file and/or the manpage for more details if necessary. +The documentation is grouped into 17 categories; the 18th button of the main +panel is inactive by default. If you have special documents which do not fit +into any of the categories, you can create a block with a new name in +texdoctk-local.dat or texdoctk-pers.dat with the respective entries. +In the settings window you see a checkbox in the html->ps and text->ps +converter menus for switching on/off output redirect. This is due to the fact +that some converters do not write their output into a file but to stdout by +default, so a redirect is needed, e.g. +a2ps myfile.txt >myfile.ps + +DISCLAIMER +texdoctk v.0.6.0 (Sep 23, 2004) - GUI for TeX documentation access +Copyright (C) 2000-2004 Thomas Ruedas +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

He also has coordinated and kept track of +several additions from other contributors, who fixed bugs and added extensions +e.g. for use under Win32 systems. +Reinhard Kotucha and Andreas Werner made very valuable comments and suggestions +to enhance v.0.3.0, especially about the special treatment of Netscape. +Reinhard Kotucha also made many useful suggestions and provided patches for +v.0.4.0; unfortunately, I could not implement all these ideas yet. +Hans Fredrik Nordhaug made some suggestions, e.g. concerning local and +personal texmf trees, and reported several bugs in different releases; he also +contributed fixes/patches. +Adrian Bunk also has reported a bug and contributed a small manpage for the +program. He made a Debian GNU/Linux package of texdoctk. +Michael Sanders reminded me to set the permissions right in the tarball. +As this is my first application written in PerlTk, it happened that I could +not solve every problem with my book and the other documentation, but had to +ask for help on comp.lang.perl.tk. Paul R. Andersen and Stephen O. Lidie have +given helpful replies and examples for me to try out. +Fabrice Popineau, and possibly others who I don't know, have provided +portability to Win32 platforms for use with fpTeX. Staszek Wawrykiewicz helped +making it ready for use with new TeXLive editions. +Paul Szabo pointed out a potential security risk related to the way names of +temporary files are generated. + +TO DO LIST +Unfortunately, I didn't have time to implement all suggestions made by the +aforementioned people; I hope that I can do that at some later time: +- widget placement in topic toplevels becomes ugly when the toplevel is + stretched or shrunk; should be made more elegant +- raise existing texdoctk window instead of possibly running texdoctk twice; + (this seems to be difficult, because it requires interprocess communication + which is kind of unsafe and requires the use of perl -T) +Possible further long-term enhancements: +- maybe use Williams Catalogue for automatically building database during + installation +- refined printing facility + +BUGS +Netscape error output will be written to stderr even if the quiet mode was set, +because I didn't manage to start it with the "inline" perl script. +Widget placement in topic toplevels becomes ugly when the toplevel is stretched +or shrunk. +The font in the frame labels of the Settings menu are not forced to the default +font; this will become visible e.g. at hi-res screens, where the label font is +not scaled up. +Please let me know if you find bugs or have suggestions for improvements. + +HISTORY/CHANGES +v.0.6.0 Sep 23, 2004 + - Unknown document formats will be opened as plain text with the text + file viewer by default; the Settings menu was given a new button to + toggle this behaviour. + - Allow for texmf-dist and texmf-doc trees for compliance with teTeX 3 + and TeXLive. + - Made an attempt to allow for additional personal user's databases to + be located in $HOMETEXMF, following a long-standing suggestion of + H.F.Nordhaug. Additional local and personal databases do not need + to be copies of the system database; instead their contents will be + appended to the entries of the default list. + - Fixed a bug with the handling of the local texmf tree reported by + Sebastian Luque. + - Updated this README and the manpage. +v.0.5.2 May 20, 2004 + - Changed the name generation of temporary files to something random + in order to address a potential security risk pointed out by Paul + Szabo. + - Replaced -q option for enabling "quiet" behaviour by -v option for + enabling "verbose" behaviour; quiet behaviour is now the default and + was extended to suppress the popup of Warning windows (popmsg level + 1). + - Added a possibility to have the Settings menu write the user's + ~/.texdocrc (older suggestion by R.Kotucha). NB: It is not intended + to write the system-wide texdocrc.defaults, because it does not set + $TEXDOCPATH and $LOCALDOCPATH. + - Button colours are made configurable through the texdocrc files or + the Settings menu. This is intended to fix a problem H.F.Nordhaug + reported with users of newer versions of the KDE, where some button + colours suddenly where messed up. - Validity of entered colours + is checked if X11's showrgb program is available. + - DVIPS_OPTS, PDFPS_OPTS and PRINT_OPTS in texdocrc.defaults are now + obsolete, but still supported. It seemed more reasonable to treat + the contents of DVIPS_CONV, PDFPS_CONV and PRINT_CMD as command lines + (which actually would have already been possible all the time). The + same is true for the viewer variables. + - Command line options can now be grouped (i.e. -av instead of -a -v). + - Cursor changes from arrow to watch in some tasks, to indicate a + process which takes a bit of time. + - fixed some glitches in databases: semicolons at the end of the + pdfTeX-related entries; corrected description of ltxtable (hint by + Rolf Niepraschk) and changed its position; corrected description of + AMSguide (AMS TeX instead of AMS LaTeX) (hint by H.F.Nordhaug) + - several additions by other contributors, for instance support for + Win32 systems +v.0.5.1 April 21, 2001 + - Enhanced right-button search function so that compressed doc files + are also found. + - Fixed a bug in the documentation finding subroutine reported by H.F. + Nordhaug: the compression determination block in sub finddoc was + broken. + - Improved treatment of entering an empty string in the search: + this is now explicitly treated as demand for display of the whole + database, instead of search for a null string. + - Automatic selection of list item in listbox if it contains only one + element; this will frequently happen in search results. In this + context, the autoview flag (option -a) has been introduced in the + texdocrc.defaults and the Settings menu: if it is chosen, the + appropriate viewer will be started automatically in the case of + one-item listboxes. + - Made <Ctrl-q>, <Ctrl-s>, <Ctrl-t> and <Ctrl-h> definitions active in + all widgets; thus, you don't need to type <Ctrl-q> in the main window + to quit, for example. Introduced new global key binding for raising + the main window (<Ctrl-m>). + - Fixed a braindead typo in the texdoc-*.dat files (too dumb to tell). + - Some small changes/updates in the Help text; the button and window + are now named "Help/About". + - Added an emacs perl-mode directive at the end, mostly for my + convenience. +v.0.5.0a April 19, 2001 + - Fixed bug in texdoc-102.dat reported by H.F.Nordhaug: correct path + for multirow is latex/multirow/multirow.sty (instead of + latex/misc/multirow.sty, as in texdoc-100.dat) +v.0.5.0 April 18, 2001 + - For some packages, the only documentation is included in the .sty + file itself. This documentation is now made accessible by extracting + the comments/instructions, writing them into a temporary text file + and calling the text file viewer on it. Thus 38 additional + documentation files are made accessible now. + - implementation of a suggestion by Hans Fredrik Nordhaug: contents of + the local texmf tree ($TEXMFLOCAL) can be included now. Arbitrary + inclusion of additional private texmf trees is not yet possible, + though. + - Two fixes/improvements in the databases by R.Kotucha were made + (concerning epslatex and the MetaPost tutorial) + - R.Kotucha suggested the use of the program xwininfo to determine + screen resolution and switch to a larger font size at hi-res screens. + He provided a patch for this, which I added after a slight + adaptation. + - auto-determination of Perl's path (stolen from some script by Thomas + Esser, IIRC) + - If a beta release of teTeX is used, the teTeX-1.0.2 database will be + used as a default instead of the 1.0.0 database + - introduced new message type with transient windows + - fatal error messages if essential config/database files are not found + - some syntax cosmetics +v.0.4.0 June 11, 2000 + - implementation of several suggestions by Reinhard Kotucha and + Andreas Werner: + * More than 1 document can now be viewed at one time, because the + viewers now run as background processes. They are not killed when + texdoctk itself is quit. + If Netscape is your browser, HTML documents are now loaded into + an existing Netscape window; no new Netscape will be started. This + is to be a bit economic with system resources. + * The Search button resp. <Ctrl-s> now switches on/off the search + entry widget; this is to avoid that multiple entry widgets come up, + because that doesn't make much sense. + * If no TXT_VIEWER is defined, the environment variable $PAGER will + be used, if defined (but see below). + - bugs/fixes and suggestions reported by Hans Fredrik Nordhaug: + * $j for loop in sub srchstr was too short: + $j<$maxind[$i] --> $j<$maxind[$i]+1 + * misplaced last SRCH in keywords branch of sub srchstr: last SRCH + had to be put into inner if block + * added support of zip compression format + - bug/fix reported by Adrian Bunk: + * ambiguous use of redirection flag/sign hor html and text->ps + conversion + - own text viewer for plain text documentation files; this is now the + default in the original texdocrc.defaults + - kpsewhich instead of find is used for rescue file search + - temporary files generated when printing or possibly decompressing (as + in Debian) now get different names to prevent overwriting files which + are still in use + - main, settings, and help windows made non-resizable + - suppressed availability of listbox selection to X selection + - document selection toplevel windows will be raised now instead of + being opened twice or more times if they are already open + - uniform font for all text-containing widgets explicitly set; I had + some weird font configuration when running texdoctk under a CDE + - environment +v.0.3.0 March 11, 2000 + - first full public release + - implementation of some suggestions by Thomas Esser: + use of kpsewhich, changes in directory and database configuration + implemented cd to file directory to ensure rendering of graphics + made viewer message output suppression really quiet + better layout of help window +v.0.2 March 7, 2000 + - first public release (preliminary) +v.0.1 - private trial version, does not exist anymore + +AUTHOR +Thomas Ruedas +tr@geol.ku.dk +http://www.geophysik.uni-frankfurt.de/~ruedas/progs.html diff --git a/Build/source/utils/texdoctk/texdoctk.1 b/Build/source/utils/texdoctk/texdoctk.1 new file mode 100644 index 00000000000..e7aebb7098a --- /dev/null +++ b/Build/source/utils/texdoctk/texdoctk.1 @@ -0,0 +1,217 @@ +.TH TEXDOCTK 1 +.SH NAME +texdoctk \- GUI for easier access of TeX package and program documentations +.SH SYNOPSIS +.B texdoctk +-[aq] +.SH "DESCRIPTION" +.B texdoctk +is a GUI for easier access to a large part of the vast amount +of package and program documentations and tutorials for TeX and its +different derivatives (mainly LaTeX).

The optional user configuration file is ~/.texdocrc and can +override all but those system settings which affect the installation as a +whole. The preferred way of changing it is through the Settings menu. +.SS The databases +\fBtexdoctk\fP comes with a default database file ($TEXMFMAIN)/texdoctk/texdoctk.dat +with a special format. It is divided into 17 sections corresponding to the +17 buttons that are active by default. Each section begins with a line + +@\fIsection_name\fP + +where +.I section_name +is the text as it appears in the button. This title is +followed by the descriptive entries for each documentation, which have this +format: + +\fIpackage-label\fP;Short description for listbox (opt. \fIpackage-name\fP);path in doc directory;optional keywords + +(without breaking the line!). Comments (initiated with a #) and empty lines +are ignored by the program. The second field is the text displayed in the +selection listboxes of \fBtexdoctk\fP, and you will usually want to mention the name +of the package in parens along with it; the first field is a \fBunique\fP label +for the package for internal use of the program which will usually be chosen +identical to the package name, but can be different if there is more than one +documentation file coming with a package. +.PP +The administrator will probably install additional packages in the local texmf +tree. The corresponding documentation can be made accessible by an additional +database $TEXMFLOCAL/texdoctk/texdoctk-local.dat. Furthermore, individual +users possibly install additional packages in an texmf subdirectory of their +$HOME, for which they can make an individual database themselves as +$TEXMFHOME/texdoctk/texdoctk-pers.dat. After creating such files, texhash +must be executed. +.PP +Both types of databases must have the same structure as the system database, +although they need (and should) not include all its sections if there are no +additional entries. For example, if the the package +.I foo +is added to the local tree such that its documentation file is +($TEXMFLOCAL)/doc/latex/foo/foo.dvi and it is decided that it fits best into +the existing category Graphics, texdoctk-local.dat would look like this: + +@Graphics +.br +foo;Create bells and whistles (foo);latex/foo/foo.dvi;decoration + +The entry for +.I foo +will then be appended to the list of entries in the Graphics category. The 18th +button can be activated in the same way, but using a new category name; +possible entries at the beginning of the database which have not been assigned +to a category will be assigned to the default Miscellaneous, making the 18th +button active with that label. Note that you cannot have more than 18 +categories; if there are more, only the one defined last will appear and be +used. +.PP +If the documentation is included in the .sty file instead of a proper +documentation file, the optional keywords should start with +-?- directly after the semicolon, where ? is 0, 1, 2 or 3; these are flags +which indicate in which part of the .sty the instructions are placed and +should help \fBtexdoctk\fP to extract the documentation from the style and present +it without the code, which would normally be of little use. +.TP +0 +no specific place, scattered between the code +.TP +1 +at end, behind \\endinput; some .sty files have well-organized documentation +behind the end of the actual code, where TeX doesn't see it upon compilation +.TP +2 +at beginning, terminated by %%%%%%; in some other cases, some usage information +is at the beginning of the .sty as a comment terminated by a line full of % +.TP +3 +as 2, but with a blank line as termination +.PP +See the system database for plenty of examples. + +.SH "FILES" +.PP +\& $TEXMFMAIN/texdoctk/texdocrc.defaults +system-wide configuration file +.PP +\& ~/.texdocrc +(optional) personal configuration file; can also be created with the Settings menu +.PP +\& $TEXMFMAIN/texdoctk/texdoctk.dat +default database file for documentation files of the distribution +.PP +\& $TEXMFLOCAL/texdoctk/texdoctk-local.dat +(optional) local database file for documentation files +.PP +\& $TEXMFHOME/texdoctk/texdoctk-pers.dat +(optional) personal database file of individual users for documentation files +.SH BUGS +Widget placement in topic toplevels becomes ugly when the toplevel is stretched +or shrunk. +.PP +The font in the frame labels of the Settings menu are not forced to the default +font; this will become visible e.g. at hi-res screens, where the label font is +not scaled up. +.PP +Netscape and Mozilla error output will be written to stderr even if the quiet +mode was set. +.SH AUTHOR +.B texdoctk +was written by Thomas Ruedas <tr@geol.ku.dk>. +.PP +This manual page was originally written by Adrian Bunk <bunk@fs.tum.de> for +the Debian GNU/Linux system (but may be used by others).

They are usually available as .dvi, +.ps, .pdf, .html or plain text files (sometimes included in the +.sty files instead of a separate documentation file) and can be +accessed with this browser, which is simply an interface to find a +documentation more easily. It starts the respective viewer for +reading the selected documentation making use of a database file +which contains the path entries according to the current teTeX +texmf/doc structure; additional usage of a system-wide local and +of individual user texmf trees with corresponding databases is also +possible. +The documentations are grouped in several categories shown in the +main window; pressing one of its buttons lists all documentations +belonging to this topic. +The topic window lets you select one documentation file, view or +send it to the default printer. By right-clicking on the selected +item you get the complete path of the file. +The search button of the main window allows you to search the +database for a string; it does not search file names. Enter the +string and hit <Return> to start the search or <Control-c> to +cancel. Just hitting <Return> without typing something in will +show the full list of files in the database. +Defaults for the documentation root directory, the viewers, the +converters, certain options and the printer are set in the global +configuration file $sysrc. +However, each user can put a copy of it as .texdocrc into his home +directory to modify them according to his needs; modification or +generation of ~/.texdocrc can also be done with the Settings menu. +Additionally, the settings can be changed temporarily with this +menu. + +The following key shortcuts are defined for use with the browser: + <Ctrl-q> Quit browser + <Ctrl-m> Raise the Main window to the foreground + <Ctrl-s> Search a keyword in database (case insensitive) + <Ctrl-c> Cancel/close subwindow or search entry widget + <Ctrl-v> View selected document (topic windows) + <Ctrl-p> Print selected document (topic windows) + <Ctrl-t> Open settings menu + <Ctrl-k> Kill fatal error message window (same as + <Ctrl-q>) + <Ctrl-h> Open this help + <Return> Equivalent to button press; + OK in selection menu and search + <Tab> Next/previous widget + +There are the following command line options: + -a autostart viewer if a listbox of search results + contains only one item; can also be set in a + configuration file + -v disable suppression of viewer messages sent to + stderr and of certain permanent message popup + windows, in case this was not set in a + configuration file; default: off + +Some more information is available in the manpage of texdoctk. + +Comments and suggestions to: +Thomas Ruedas +tr@dlc.ku.dk or tex-k@tug.org +# Local Variables: +# mode: perl +# auto-fill-hook: do-auto-fill +# End: +# vim: ts=8 sw=4 noexpandtab |
