markdown-it-concat-code

Concatenate all or some fenced code blocks from a markdown file.

Usage

const md = require('markdown-it')()
  .use(require('markdown-it-concat-code'), opts, src);

The opts object can contain:

Name	Type	Description
lang	string	Only include code blocks specifying `lang' as the language. If not specified, null or empty string then return all fenced code blocks.
separator	string	Append this string after each code block included in output. Defaults to '\n'.

src is an object whose value will be filled with the concatenated code blocks.

Example

const mdconcat = require('./').default
 
var mds = fs.readFileSync('README.md', 'utf8');
var src = {};
 
// all code blocks
md().use(mdconcat, {}, src).parse(mds, {});
 
console.log(src.value);
 
// with `lang` specified
md().use(mdconcat, { lang: 'c' }, src).parse(mds, {});
 
console.log(src.value);
