PROJECT VPE +============== +VPE deals with source specials for pdf files: clicking +on special annotations will launch an editor with the +source file at the source line. + +The project supports three routes to pdf files: + +* VTeX/Linux route: + MicroPress' VTeX is able to insert specials by itself. + It smoothly works under Windows. But the AcrobatReader + versions under Linux/Unix require additional work, see + section H "Linux launch details", that is done by the + perl script `vpe.pl'. + +* pdfTeX route: + For Han The Thanh's pdfTeX under Linux/Unix or Windows + the package `vpe.sty' inserts the specials with the + help of the perl script `vpe.pl'. + The catalog entry `/AcroForm' is added, so that + the `revert' menu entry of AR4.05 is enabled for + easier reloading, if the pdf file has changed. + Users of AR4.05 can also try option `form' of + the package to get nicer source special markers, + but the memory consumption is higher. + +* dvips route: + As in the pdfTeX route package `vpe.sty' inserts the + specials with the help of the perl script `vpe.pl'. + Also the `/AcroForm' entry is added, but the + `form' option is not implemented. + +B. COPYRIGHT, DISCLAIMER, LIZENZ +================================ +Copyright (C) 1999, 2000, 2012 Heiko Oberdiek. + +This program may be distributed and/or modified under the +conditions of the LaTeX Project Public License, either version 1.2 +of this license or (at your option) any later version. +The latest version of this license is in + http://www.latex-project.org/lppl.txt +and version 1.2 or later is part of all distributions of LaTeX +version 1999/12/01 or later. + +C. FILES +======== +The project `vpe' consists of three files: + +vpe(.pl): Perl script, used by all routes. The extension `.pl' + may be omitted for installation purposes. +vpe.sty: LaTeX2e package for pdftex and dvips routes. +README: Documentation, the file you are reading. + +Help and temporary files, generated by use: +myfile.tex.vpe: Symbol link from source file `myfile.tex' + to the perl script, required for the source + specials launch actions in the pdf file. + Each source file need a link. +myfile.vpe: Temporary file for data exchange between + TeX and the perl script called by \write18{}. +vpe.cfg: Configuration file of package `vpe.sty'. + +D. REQUIREMENTS +=============== +All routes: +* Perl5 (version 5 of the perl interpreter). + +pdfTeX, dvips routes: +* \write18 feature (--shell-escape) +* LaTeX2e + +pdfTeX route: +* pdfTeX >= v0.14 + +E. INSTALLATION +=============== +1. TeX directory structure (TDS): + The files + `vpe.txt' (documentation) + `vpe.sty' (pdf(e)tex, pdf(e)latex, (e)tex, (e)latex) + go to + texmf/doc/latex/oberdiek/vpe.txt + texmf/tex/latex/oberdiek/vpe.sty + +2. Perl script `vpe.pl': + + Unix + * Your are allowed to rename `vpe.pl' to `vpe': + mv vpe.pl vpe + * Ensure that the execute permission is set: + chmod +x vpe + * Move the file to a directory where the shell can find it + (environment variable PATH, e.g. /usr/local/bin/). + * The environment variables TEXEDIT and VPE are + looked for the editor call, eg: + export VPE='xterm -e joe +%d %s' (bash) + %d will be replaced by the line number and + %s by the file name. + + Windows (Dos) + * Methods for calling by typing the script name without extension + and perl interpreter: + a) If your perl distribution provides a pl2exe program, + use it to generate `vpe.exe'. + Advantage: I/O redirection works. + b) A good method is a dos program of John Dallman: + #!perl.exe (versions below 4) + hbperl.exe (version 4) + http://www.perl.com/CPAN/authors/id/JDALLMAN/hbp_403.zip + Move vpe.pl in a PERLLIB directory and copy the + exe program to `vpe.exe'. Then the program looks + for the perl interpreter, the script and calls them. + Advantage: I/O redirection works. + c) Windows NT 4.0 users can use associated file types: + SET PATHEXT=.pl;%PATHEXT% + See perl win32 faq "How do I associate Perl scripts with perl?": + http://www.activestate.com/support/faqs/win32/perlwin32faq4.html + Disadvantage: I/O redirection does not work. + d) 4DOS: SET .PL=c:/bin/perl.exe + See perl win32 faq "How can I get Perl to run a Perl script at + the 4DOS command line by typing the name of the script without + the extension or "perl", just like a regular exe file?": + http://www.activestate.com/support/faqs/win32/perlwin32faq1.html + e) Convert the perl script to a batch file `vpe.bat', if your + distribution provides `pl2bat.bat'. + Disadvantage: I/O redirection does not work. + Many of this methods are listed in the perl win32 faq + "What's the equivalent of the shebang ("#!") syntax for Win32?": + http://www.activestate.com/support/faqs/win32/perlwin32faq4.html + * Running the perl interpreter directly with the perl script: + perl vpe.pl ... + Use this method only, if the other methods fail. + Then you have to configure the command name in the + configuration file `vpe.cfg': + \vpesetup{command={perl vpe.pl}} + * The editor application and the syntax of the paramters + for the editor can be configured by \vpesetup in + the configuration file `vpe.cfg': + \vpesetup{application={pfe.exe},parameters={-g $d $s}} + $d will be replaced by the line number, + $s by the file name. + +F. HOWTO +======== + +F.1 VTeX/Linux +-------------- +Do not use the package `vpe.sty', the VTeX/Linux route +is only based on the perl script. + +a) Enable VTeX's source special generation with option `-*<num>', + eg: -*20 +b) Run the perl script on the generated pdf file. It + fixes the launch actions and creates the necessary symbol + links (See section H "Linux launch details"): + vpe myfile.pdf + +F.2 PdfTeX and dvips +-------------------- +a) Load the package `vpe.sty', eg: + \usepackage{vpe} +b) Produce the pdf file, but with enabled \write18{} feature + for system commands. This can be achieved by setting the + command line option `--shell-escape' for pdfTeX or TeX. + An alternative is the boolean variable `shell_escape' + in the configuration file `texmf.cnf'. For security + reasons I recommend the command line option. +c) Only Linux: After the first call it is possible that + the symbol links are not created yet (depends on write + puffer effects). Then it can be done by envoking the + perl script manually: + vpe myfile.pdf + +F.3 (X)emacs +------------ +This section is provided by Uwe Brauer. + +In order to use vpe with (X)emacs, you will need to set a +client as the editor variable since otherwise for each +call a separate (X)macs session would be started. There +are two server/clients: gnuclient which is shipped with +xemacs and emacsclient which is shipped with GNU emacs. +The configuration for emacsclient is a little more +delicate, that's why in the following only the +configuration of gnuclient is discussed. Either install +gnuclient for GNU emacs or, if you want to use emacsclient, +read the following instuctions +http://xdvi.sourceforge.net/inverse-search.html. + +* insert in your .emacs the line + (gnuserv-start) + +* set the variable VPE, either + setenv VPE 'gnuclient -q +%d %s' + in your .tcshrc file or + export VPE='gnuclient -q +%d %s' + in your .bashrc file + +* now if you want to avoid that a new window(frame) is + opened every time you call the gnuclient, insert + something like this in your .emacs file + + (custom-set-variables + ;;; ... other stuff ... + '(gnuserv-frame t) + '(gnuserv-visit-hook (lambda () (raise-frame) (recenter)))) + +* If you use AuCTeX, the following definitions come in handy: + Copy in your .emacs file + + (custom-set-variables + '(TeX-command-list (quote ( + ;; ..other stuff.. + ("srcpdflatex" "pdflatex --shell-escape %t" TeX-run-command t "nil") + ("vpe" "vpe %g" TeX-run-command t nil)))) + '(TeX-expand-list (quote ( + ;; ..other stuff.. + ("%g" file "pdf" t))))) + + If you don't want to use %g for pdf files, use another letter + but make sure that it is not already in use. + Now you can call srcpdflatex for generating an appropriate pdf + file and the perl script vpe to insert the source specials. + +G. USER INTERFACE +================= + +G.1 Perl script +--------------- +General options: +--help: print help and usage screen. +--verbose: print additional informations. + +Options that influence the symbol links: +--force: force symbol links (`ln -f' is called). +--delete: remove the symbol links for the source files, + mentioned in the pdf file: + vpe --delete myfile.pdf + +Internal options, called by the package `vpe.sty': +--system: detects the system (linux or win) and writes + the information in the data exchange file: + vpe --system myfile.vpe +--sty: generates the absolute file name of the + source file `file.tex', get the maximum + line number and writes the informations + in the data exchange file `myfile.vpe': + vpe --sty file.tex myfile.vpe +--progname: this option sets the program name option + of `kpsewhich', called by the --sty option: + vpe --sty --progname=pdfelatex file.tex myfile.vpe + +G.2 Package +----------- +There are three places, where the options can be specified +in evaluation order: +a) Configuration file `vpe.cfg` with \vpesetup. +b) LaTeX package options: local in \usepackage or + global in \documentclass. +c) Some options can be set by \vpesetup after the + package is loaded. + +`active', `inactive' (place: abc, default: active) + Enables/disables insertion of source specials + +`debug' (place: a, default: off) + Verbose messages for debugging purposes. + +`dupes', `nodupes' (place: abc, default: dupes) + Option `nodupes' suppresses source specials that point + to the same file and line. + +`linux', `unix', `win', `dos' (place: ab, default: automatic) +`system=linux|win' (place b) + The format of the launch action differs in the win and unix + case. Therefore the packages has to know, which kind it + should generate. If none of the options is given, then + the packages calls the perl script with option `--system' + to get the information. + (Recommendation: set in `vpe.cfg' to save time.) + +`form', `noform' (place: ab, default: noform) + Users of AR4.05 can try this option to get nicer + source special marks. Only the pdfTeX route is + supported currently. + +`acroform', `noacroform' (place: ab, default: acroform) + With forms AR4.05 enables the `revert' menu entry, + so that changed files can more easily be reloaded. + If option `form' is used, the /AcroForm dictionary + can be suppressed with `noacroform', when another + /AcroForm is already provided. + +`command=...' (place: bc, default: vpe) + Call of the perl script for the \write18{} feature. + +`progname=...' (place: bc, default: automatic) + TeX cannot provide absolute path names of files, + therefore the package calls the perl script to ask + `kpsewhich'. This program needs the program/format + name in order to select the correct search path + variables. Automatically the package is able to + distinguish between `latex', `elatex', `pdflatex' + and `pdfelatex'. For other names this option has + to be set. + +`application=...' (place: bc, default: pfe.exe) +`parameters=...' (place: bc, default: `-g $d $s') + These options configure the editor call for windows: + `application' contains the call of the editor, + `parameters' the parameters for the editor. + $d will be replaced by the line number and + $s by the file name. + +`width', `height', `depth', `color', `border', +`flag', `attr' (place: bc, default: see vpe.sty) + With these options the launch annotation + can be configured (`noform' version). + Because of the beta status of the options, + they can change in future, for details see + the package source. + +`everyhbox', `noeveryhbox' (place: ab, default: noeveryhbox) + By this option a lot of source specials are inserted, + but there is a high risk to get a lot of "Underfull + \hbox" warnings. + +`no<feature>' (place: a, default: <feature>) + For the introduction of source specials many + internal commands are redefined. This can cause + problems with incompatible packages and macros. + The redefinitions that cause problems can be + disabled. Current list of features: + input, @input, include, + newpage, clearpage, + everypar, document, @item, @doendpe, + @arrayparboxrestore, @xsect, @afterheading, + @setminipage, @startsection, + everymath, everyhbox, + newline, mbox, TILDE, + ref, cite, + item, trivlist, endtrivlist, + @bsphack, @esphack, @Esphack, @xaddvskip, + @tabularcr, @arraycr, + hrule, vrule + +H. LINUX LAUNCH DETAILS +======================= +It is quite easy to launch a program with parameters +with a link annotation under Windows, because +AcrobatReader knows a /Win dictionary, eg: + << /Type Annot + /Subtype /Link + /Rect [100 700 120 720] + /A << /Type /Action + /S /Launch + /Win << /F (pfe.exe) + /P (-g 21 c:/myhome/myfile.tex) + >> + >> + >> +A corresponding /Unix dictionary is not yet defined +in the pdf specification and not implemented in AR. +Therefore only the file name can be used to store +the parameter informations, eg: + /A << /Type /Action + /S /Launch + /F (//.////../myhome/myfile.tex.vpe) + >> + +The file that will be launched is a symbol link +to the script `vpe(.pl)', eg: + ln -s /usr/local/bin/vpe /myhome/myfile.tex.vpe + +The script scans its calling name, the name of the +symbol link, to extract the parameters for the +editor call: +* The initial part encodes the line number, +* the rest without the extension `.vpe' is the + file name. +* Condition: The path names are absolute path names. + +The coding algorithm for the line number: +* The decimal digits of the number are separated + and ended by the sequence "./". +* Each decimal digit of the number is converted + to a sequence of slashes, optionally followed + by a period. The count of slashes is the + number. With the period, the count have to be + incremented by 5. +* The conversion of the first digit always starts + with a slash to ensure a absolute path names, + eg: "5" is converted to "/////", but not as + first digit it can be shrunk to ".". +Examples (spaces only for clarifying): + 2: // ./ + 6: /. ./ + 9: ////. ./ + 11: / ./ / ./ + 28: // ./ ///. ./ (see example above) + 505: ///// ./ ./ . ./ + +I. AUTHOR +========= +Heiko Oberdiek +Email: heiko.oberdiek at googlemail.com + +J. QUESTIONS, BUG REPORTS +========================= +If you have questions, problems with `vpe', error reports, +if you have improvements or want to have additional features, +please send them to the author. + +Because I do not have to much time, I cannot garantee +that I will fix all problems and add all suggested features. + +Regarding bug reports I have some wishes: +* Please only send a minimal test file. + I do not have the time to check hundreds of lines + and pages. + Strip the minimal file off all unnecessary packages, + macros, and stuff. + But the minimal file should be complete, so that I can + immediately call latex on it. +* Please no .log, .dvi, .ps, .pdf files. + I have a lot of TeX and related programs installed + and can generate them in the most cases. +* Please get all versions numbers of packages and + programs (examples see below). Only the + distribution version does not help, so I do not + have MikTeX installed and I am using a very old + teTeX and even emTeX, but almost always the latest + pdfTeX binaries. Therefore the pdfTeX version is + much more important. + Hints: + * With "\listfiles" LaTeX prints the versions of the + used files at the end of the .log file. + * Many programs know options like: + --version, -v, -help, -h, -? + +My environment for developing and testing (2000): +* linux, debian 2.0 +* perl 5.004_04 +* VTeX/Linux: 7.06 +* pdfTeX: 0.14g-pretest-20000912 +* TeX: 3.14159, Web2C 7.2 +* dvips 5.78 +* Ghostscript 6.01 + +K.
