Full description
This file contains a command to read Perl documentation in Emacs. It uses two external commands which come with Perl: `perldoc` to locate the Perl documentation for the Perl modules installed on your system, and `pod2html` to format the documentation to HTML. This HTML version is then displayed using Emacs' "simple HTML renderer" shr. Motivation Perl documentation is written in a markup format called POD ("Plain Old Documentation") and is usually converted to other formats for reading by humans. The documentation used to be available in Emacs for a long time in 'info' or 'man' format. However, Perl does no longer ship 'info' files, and the software available from CPAN never did. 'man' is not available on all platforms and allows only rather restricted formatting, most notably linking between documents does not work. On the other hand, Perl provides a converter from POD to HTML. HTML is well supported by Emacs and is well suited for presentation of structured documents. The user visible benefits over the other formats are: * Works nicely on platforms which do not have man * Unlike with 'man', Hyperlinks between POD documents work and resolve to POD documentation on your system, no web server required. * Makes use of Emacs faces: variable-pitch font for text, fixed-pitch for code, italics for, well, italics

perl-doc.el for GNU Emacs NEWS -- history of user-visible changes. Copyright (C) 2023 Free Software Foundation, Inc. See the end of the file for license conditions. * Changes in perl-doc.el 0.8 - August 2023 ** Speedbar Support perl-doc now has its own display in speedbar. It is accessible either by starting <M-x> speedbar while looking at a buffer in perl-doc-mode or by starting <M-x> perl-doc-browser. In the latter case, which also works if emacs is started in a terminal, you can leave perl-doc display with the command <M-x> perl-doc-browser-quit (bound to "q" in the speedbar frame). ** Completion of module names The perl-doc command now offers completion for modules which are installed on your system (fine print: The modules who are available to the Perl executable customized as perl-doc-perl-program). ** New functions Documentation for builtin functions and variables is now available via the new commands perl-doc-function and perl-doc-variable. They don't do completion, though (I have no easily accessible authoritative source for the completion candidates). The commands perl-doc-browser and perl-doc-browser-quit start and stop perl-doc view in speedbar. The command perl-doc-add-lib allows to add an existing directory (with completion) for the current session. To add a directory permanently, see the new customization option perl-doc-extra-libs below. ** New customization options The option perl-doc-perl-program is the file name of the Perl executable for which documentation is to be displayed. perl-doc.el runs the one-liner "perl -E 'say for @INC'" to get the list of directories where Perl modules (and their documentation) reside. The option perl-doc-extra-libs allows to add a list of directories, on top of the builtin ones and those from PERL5LIB. ** Bugfixes Refreshing the view doesn't happen quite as often (only if the width of the window changes), and if it ever happens, it does no longer kill imenu's menubar-index (errors reported by LanX on PerlMonks) ** Known bugs and limitations The display of Perl documentation is done in a scratch buffer which is not associated with a file. This means that there's no point in editing this buffer or saving it. The error handling could be better. If a Perl documentation buffer shows "No documentation found for Your::Module", then you don't know whether the file Your/Module.pm has no POD in it or whether it does not exist at all. In the former case, you can still use "v" to view the source of Your/Module.pm (and add some POD, of course), the latter should not happen if you let yourself be guided by the module name completion. * Changes in perl-doc.el 0.6 Bugfix: A vertical bar in markup is now processed correctly (seen in perlport.pod). * Changes in perl-doc.el 0.3 ** New command `perl-doc-file' Like `perl-doc', but prompt for a file name with completion. ** New command `perl-doc-view-source' View the POD source for the Perl documentation shown in the current buffer. The command is bound to "v" in `perl-doc-mode'. ---------------------------------------------------------------------- perl-doc.el 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 3 of the License, or (at your option) any later version. perl-doc.el 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.
