unist-util-source

Unist utility to get the source of a Node or Position.

Installation

npm:

npm install unist-util-source

Usage

Say we have the following file, example.md:

> + **[Hello](./example)**
>   world.

And our script, example.js, looks as follows:

var vfile = require('to-vfile')
var unified = require('unified')
var parse = require('remark-parse')
var source = require('unist-util-source')

var file = vfile.readSync('example.md')
var tree = unified()
  .use(parse)
  .parse(file)

var list = tree.children[0].children[0]
console.log(source(list, file))

Now, running node example yields:

+ **[Hello](./example)**
  world.

API

source(value, doc)

Parameters

• value (Node or Position) — Value to get
• doc (VFile or string) — Document in which value exists

Returns

string? — Source of value in file, if available.
