Pod::WikiDoc::Cookbook - Examples of Pod::WikiDoc usage

DESCRIPTION

This file contains some examples of ways to use Pod::WikiDoc or to integrate Pod::WikiDoc with other tools.

BASIC RECIPES

Editor settings for working with Pod::WikiDoc

(Seeking equivalent settings for other editors or alternatives for vim.)

Vim

In vim, use the comments and formatoptions settings in .vimrc to have vim automatically insert the wikidoc comment leader when pressing return from a wikidoc comment line. For example, the following lines in a .vimrc file will activate this option whenever a perl-ish file is loaded.

autocmd BufNewFile,BufRead *.p? set comments=b:###
autocmd BufNewFile,BufRead *.p? set formatoptions+=r

Subclassing Module::Build to automatically generate Pod from wikidoc

With a little extra work in the Build.PL file, Pod::WikiDoc can work easily with Module::Build to extract wikidoc into .pod files automatically during the distribution process

The Build.PL file below subclasses Module::Build with three functions:

  • ACTION_wikidoc -- adds a new Build wikidoc action that extracts Pod and wikidoc from all .pm files in the lib directory and adds them to the MANIFEST

  • ACTION_testpod -- adds a dependency on the wikidoc action to regenerate .pod files before testing them

  • ACTION_distdir -- adds a dependency on the wikidoc action to regenerate .pod files before bundling up a distribution

By making wikidoc extraction part of the distdir action, users installing the distribution will receive it with .pod files already created, and will not need to have Pod::WikiDoc installed themselves. Note: this subclassing can't be emulated in a "traditional" Makefile.PL as created by Module::Build::Compat using the create_makefile option in Module::Build. As the "passthrough" style is also problematic for some users, I recommend leaving off any Makefile.PL and using Build.PL only.

    # Build.PL
    use Module::Build;

    my $class = Module::Build->subclass(
        class => "Module::Build::WikiDoc",
        code => <<'SUBCLASS' );

        sub ACTION_wikidoc {
            my $self = shift;
            eval "use Pod::WikiDoc";
            if ( $@ eq '' ) {
                my $parser = Pod::WikiDoc->new(
                    { comment_blocks => 1}
                );
                for my $src ( keys %{ $self->find_pm_files() } ) {
                    (my $tgt = $src) =~ s{\.pm$}{.pod};
                    $parser->filter( {
                        input   => $src,
                        output  => $tgt,
                    });
                    print "Creating $tgt\n";
                    $self->_add_to_manifest( 'MANIFEST', $tgt );
                }
            }
            else {
                warn "Pod::WikiDoc not available. Skipping wikidoc.\n";
            }
        }

        sub ACTION_testpod {
            my $self = shift;
            $self->depends_on('wikidoc');
            $self->SUPER::ACTION_testpod;
        }

        sub ACTION_distdir {
            my $self = shift;
            $self->depends_on('wikidoc');
            $self->SUPER::ACTION_distdir;
        }

    SUBCLASS

    $class->new( 
        # regular Module::Build options
    )->create_build_script;
