Pod::Markdown::Githubert - convert POD to Github-flavored Markdown


    use Pod::Markdown::Githubert ();

    my $parser = Pod::Markdown::Githubert->new;
    $parser->output_string(\my $markdown);

    # see Pod::Markdown docs for the full API


Pod::Markdown::Githubert is a module for converting documents in POD format (see perlpod) to Github-flavored Markdown. It is a subclass of Pod::Markdown (which see for API documentation) that adds the following Github-specific enhancements and fixes:

  • Internal links (of the form L</foo>) are converted to something that hopefully matches how Github generates HTML ids for Markdown headings. In short, internal links to a section of the current page should just work when rendered on Github.

  • Github-specific Markdown code can be embedded literally using a =for github-markdown paragraph or =begin github-markdown ... =end github-markdown section.

    In other words, if you want to render e.g. a badge, but only on Github, not all Markdown renderers, put it in a =for github-markdown paragraph.

  • External links to module documentation normally point to But that doesn't work for some of the manual pages included with Perl because they are only generated when perl is built (such as perlapi), so this module redirects all perlXYZ links to, which has the full set.

  • Verbatim paragraphs are translated to fenced code blocks (surrounded by ```) with normalized indentation (meaning it doesn't matter whether the paragraph is indented by 1 space, 4 spaces, or 23 spaces in the POD source; it will generated the same Markdown).

  • Code blocks containing ``` are rendered correctly, as are code blocks in nested structures (such as list items) even when a numbered list item starts with a code block.

  • Syntax highlighting can be enabled by tagging each code block with its language. As this module translates a POD document, it keeps a global "current language" setting, which is applied to every verbatim paragraph. Initially the "current language" is empty, which just produces ordinary ``` code blocks.

    A =for highlighter language=FOO paragraph sets the "current language" to FOO. (More specifically, you can put multiple KEY=VALUE options in a =for highlighter paragraph, but this module only looks at the language option.) If you only want to set the "current language" to FOO, you can also write =for highlighter FOO (that is, language is the default option).

    The "current language" is applied to all following verbatim paragraphs and produces ```FOO tagged code blocks:

        =for highlighter language=perl
            my $dog = "spot";
        ... other stuff ...
            my $car = "cdr";
        =for highlighter language=html

    produces the following Markdown code:

        my $dog = "spot";
        ... other stuff ...
        my $car = "cdr";
