[description]
The package [package Markdown] provides a command to convert
Markdown annotated text into HMTL.
[list_begin definitions]
[call [cmd ::Markdown::convert] [arg "markdown"]]
This command takes in a block of Markdown text, and returns a block
of HTML.
[para] The converter supports two types of syntax highlighting for
fenced code blocks: highlighting via a registered converter
(see [cmd ::Markdown::register]), or pure JavaScript highlighting,
e.g. via "highlight.js", where the language specifier used in the
markup is set as CSS class of the "code" element in the returned markup.
[call [cmd ::Markdown::register] [arg "langspec"] [arg "converter"]]
Register a language specific converter for prettifying a code block
(e.g. syntax highlighting). Markdown supports fenced code blocks with
an optional language specifier (e.g. "tcl"). When the markdown parser
processes such a code block and a converter for the specified langspec
is registered, the converter is called with the raw code block as
argument. The converter is supposed to return the markup of the code
block as result. The specified converter can be an arbitrary Tcl
command, the raw text block is added as last argument upon invocation.
[call [cmd ::Markdown::get_lang_counter]]
Return a dict of language specifier and number of occurrences in
fenced code blocks. This function can be used e.g. to detect, whether
some CSS or JavaScript headers should be included for rendering
without the need of postprocessing the rendered result.
[call [cmd ::Markdown::reset_lang_counter]]
Reset the language counters.
