Perl Doc Plugin

This Plugin extracts the Perl documentation (POD) from a Perl module located in the @INC library path and displays it in a topic.

Syntax Rules and Example

Write %PERLDOC{"Module"}% to display the documentation of a Perl module, for example %PERLDOC{"File::Copy"}% shows the doc of File::Copy. Optionally use a format="pod" parameter to see the raw POD format, or format="twiki" to see the TWiki markup text.

Use the following form to see the documentation of a Perl module: (this Plugin needs to be installed and enabled)

Perl module name: in format

%PERLDOC{"" format=""}%

Perl code with POD (Plain Old Documentation)

Perl code may contain blocks of documentation. A block typically starts with a =pod or =head1 at the beginning of a line, and ends with =cut at the beginning of a line or at the end of the file. Read the details in http://www.perldoc.com/perl5.6/pod/perlpod.html

POD example:

=head1 Demo of POD

Silly paragraph


Perl code with TWiki markup

TWiki markup can be used inside a =begin twiki ... =end twiki block. Keep in mind that this markup gets parsed correctly only by the PerlDocPlugin, other POD translator ignore the block. The TWiki markup is richer and more compact then POD. Example:

=begin twiki
---++ Demo of TWiki markup
Silly paragraph

=end twiki
