NAME

Markdown::Perl – Very configurable Markdown processor written in pure Perl, supporting the CommonMark spec and many extensions.

SYNOPSIS

This is the library underlying the pmarkdown tool. It can be used in an object-oriented style:

  use Markdown::Perl;
  my $converter = Markdown::Perl->new([mode => $mode], %options);
  my $html = $converter->convert($markdown);

Or the library can be used functionally:

  use Markdown::Perl 'convert';
  Markdown::Perl::set_options([mode => $mode], %options);
  my $html = convert($markdown);

DESCRIPTION

new

  my $pmarkdown = Markdown::Perl->new([mode => $mode], %options);

Creates a Markdown::Perl object that can be used to convert Markdown data into HTML. Note that you don’t have to create an instance of this class to use this module. The methods of this class can also be used like package functions and they will operate on an implicit default instance of the class.

See the "MODES" in pmarkdown page for the documentation of existing modes.

See the Markdown::Perl::Options documentation for all the existing options.

For the reference on the default syntax supported by the library, see the GitHub repository of the project: https://github.com/mkende/pmarkdown/blob/main/Syntax.md

set_options

  $pmarkdown->set_options(%options);
  Markdown::Perl::set_options(%option);

Sets the options of the current object or, for the functional version, the options used by functional calls to convert(). The options set through the functional version do not apply to any objects created through a call to new().

See the Markdown::Perl::Options documentation for all the existing options.

set_mode

  $pmarkdown->set_mode($mode);
  Markdown::Perl::set_mode($mode);

Specifies a mode for the current object or, for the functional version, the mode used by functional calls to convert(). A mode is a set of configuration options working together, typically to replicate the semantics of another existing Markdown processor. See the "MODES" in pmarkdown documentation for a list of available modes.

When a mode is applied, it sets specific values for some options but any value for these options set through the set_options() will take precedence, even if set_options() is called before set_mode(). The mode set through the functional version does not apply to any objects created through a call to new().

convert

  my $html = $pmarkdown->convert($md);
  my $html = Markdown::Perl::convert($md);

Converts the given $md string into HTML. The input string must be a decoded Unicode string (or an ASCII string) and the output is similarly a decoded Unicode string.

set_hooks

  $pmarkdown->set_hooks(hook_name => sub { ... }, ...);
  Markdown::Perl::set_hooks(hook_name => sub { ... }, ...);

Registers hooks to be called during the processing of a Markdown document. Each hook must point to a code reference. You can remove a hook by passing undef as the value associated with a hook.

There is currently a single hook:

• resolve_link_ref: this hook will receive a single string an argument, containing the label of a link reference in case where there was no matching link definition in the document and it must returns either undef or a hash-reference containing a target key, pointing to the link destination and optionally a title key containing the title of the key.
