Utilities for extracting and replacing GitHub Flavored Markdown code blocks. For example, you could easily find code blocks for a specific language and run the code through a linter.
See the example for ideas.
Install with npm:
npm i extract-gfm --save-devnpm testvar extract = require('extract-gfm');
extract.parseBlocks('abc\n```js\nvar foo = "bar";\n```\nxyz');Returns:
{ text: 'abc\n__CODE_BLOCK0__\nxyz',
blocks:
[ { lang: 'js',
code: 'var foo = "bar";',
block: '```js\nvar foo = "bar";\n```' } ],
markers: [ '__CODE_BLOCK0__' ] }str{String}: Original string with gfm code blocks.returns: {String}
Strip code blocks from a string and replaced them with heuristic markers.
str{String}: The string to parse.returns: {Array}
Return an array of all gfm code blocks found. See gfm-code-blocks for more detail.
Convenience method to make it easy to replace code blocks.
str{String}: The string to parse.returns: {Object}
Returns an object with:
text: the string stripped of code blocks, where each block is replaced with a heuristic marker.blocks: An array of code blocks, using the .extractBlocks() method.markers: An array of heuristic markers to be used for adding code blocks back.
Example
var code = require('extract-gfm');
var fs = require('fs');
var str = fs.readFileSync('README.md', 'utf8');
console.log(code.parseBlocks(str));Used for adding code blocks back into the string after they have been modified somehow.
str{String}: A string with heuristic markers to replace.object{String}: Object created by .parseBlocks()returns{String}: Updated string, with shiny new code blocks.
To customize how this is done, just look at the injectBlocks
method and create your own based on this. .parseBlocks()
really does all of the hard work.
