Parts comments and code into a data structure with htmlParser2 for html and line based comment parsing for everything else. code-part tracks starting line numbers for each code section so it's possible to add line numbers if you plan to use a syntax highlighter like google-code-prettify to display your code.
code-part's code for line based parsing was modified from docco. This code base does not include docco. The only current dependencies are htmlParser2, lodash and dox.
Comment support for everything except html only extracts comments
at the beginning of the line and only the single line version of
the languages comment. For example /* not extracted */
does not
get extracted but // extracted
does.
The dox version does the opposite. Skipping line based comments and parsing only multi-line based. Obviously dox only works with JavaScript.
To see a list of the languages supported by the line based parsing have a look at resources/languages.json.
var part = require('code-part');
// Path is used to decide which parser to use
// (html or lineBased currently) and decides comment
// parsing in lineBased.
part(path, code, config, function (err, sections) {
});
// If code is null, the specified path is assumed
// to be a path on the file system and is read in
// with `readFileSync`.
part(path, code, {
// Options used when parsing html.
// By default the parser will skip comments that start with
// `<!--[`. Set to `true` to include these as comments.
noSkipDirectives: false, // default
// Used instead of path's extension when determining
// the parser (html or lineBased). Also used in the
// lineBased parser.
// when looking up comment markers and deciding if it
// is literate (litcoffee).

It is possible to use jade, but multi-line comments are not supported.
Supported:
html
// comment 1
head
// comment 2
title A Title
Not Supported:
html
//
This is a
multi-line comment
and is not supported
head
title Another Title
