Interface to the libcmark CommonMark parser.
This module uses native library, so in order to use it, you need either build the library or install it using pre-built package. For GNU/Linux distributions the most natural way to do so it so search for libcmark package in appropriate distribution repository and install if the package is already there.
use CommonMark;
say CommonMark.to-html("Hello, world!");
# "<p>Hello, world!</p>"
say CommonMark.version-string;
# 0.28.3
CommonMark is Markdown with a proper spec - It should render most Markdown files the same; it nails down some edge cases, and specifies byte encodings.
You'll want to call .to-html($text) to convert markdown to HTML. The library itself also supports XML, LaTeX, and nroff/troff formats, but I haven't seen where it's tested. Check out the Perl 6 source for more details there.
- to-html( $common-mark )
Return HTML from CommonMark format. This is likely the only method you'll use. There's a lower-level interface that'll let you interrogate the library at the individual node level, look at the source for more inspiration.
- version()
Returns a 32-bit int containing the version number.
From the documetation:
* Bits 16-23 contain the major version.
* Bits 8-15 contain the minor version.
* Bits 0-7 contain the patchlevel.
- version-string()
Returns the library version in text form.
- parse-document( Str $buffer, int32 $options )
Returns a CommonMark::Node root of the document.
- new( :$type )
