NAME

String::Tagged::Markdown::HFM - parse and emit text with HedgeDoc Flavoured Markdown

SYNOPSIS

use String::Tagged::Markdown::HFM;

my $st = String::Tagged::Markdown::HFM->parse_markdown( $markdown );

# Conforms to the String::Tagged::Formatting API
String::Tagged::Terminal->new_from_formatting(
   $st->as_formatting
)->say_to_terminal;

DESCRIPTION

This subclass of String::Tagged::Markdown handles all of the Markdown syntax recognised by the base class, and in addition the inline span marker extensions that are recognised by HedgeDoc Flavoured Markdown, the version of Markdown used on https://hedgedoc.org.

TAGS

This module adds the following extra tags.

superscript, subscript, underline, highlight

Boolean values indicating superscript, subscript, underline or highlight. These are parsed from

^superscript^
~subscript~
++underline++
==highlight==

METHODS

as_formatting

$fmt = $st->as_formatting( %args );

Returns a new String::Tagged instance tagged with String::Tagged::Formatting standard tags.

By default the highlight tag is not handled, but optionally the caller can specify how to handle it by setting a callback in the convert_tags argument.

$st->as_formatting(
   convert_tags => { highlight => sub { ... } }
);

Alternatively, this can be handled automatically by providing a colour to be set as the value of the bg tag - either by passing the highlight_colour named argument, or setting the value of the package-global $HIGHLIGHT_COLOUR. Remember that this should be an instance of Convert::Color.

$st->as_formatting(
   highlight_colour => Convert::Color->new( "vga:yellow" )
);

new_from_formatting

$st = String::Tagged::Markdown::HFM->new_from_formatting( $fmt, %args );

Returns a new instance by converting String::Tagged::Formatting standard tags.

By default the highlight tag is not generated, but optionally the caller can specify how to generate it by setting a callback in the convert_tags argument, perhaps by inspecting the background colour.

String::Tagged::Markdown::HFM->new_from_formatting( $orig,
   convert_tags => { bg => sub ($k, $v) { ... } }
);

Alternatively, this can be handled automatically by providing a colour to be matched against the bg tag - either by passing the highlight_colour named argument, or setting the value of the package-global $HIGHLIGHT_COLOUR. Remember that this should be an instance of Convert::Color. If the value of the bg is within 5% of this colour, the highlight tag will be applied.

String::Tagged::Markdown::HFM->new_from_formatting( $orig,
   highlight_colour => Convert::Color->new( "vga:yellow" )
);
