Usage

Example

var remark = require('remark')
var find = require('unist-find')

remark()
  .use(function () {
    return function (tree) {
      // string condition
      console.log(find(tree, 'value'))

      // object condition
      console.log(find(tree, { value: 'emphasis' }))

      // function condition
      console.log(find(tree, function (node) {
        return node.type === 'inlineCode'
      }))
    }
  })
  .process('Some _emphasis_, **strongness**, and `code`.')

Result:

// string condition: 'value'
{ type: 'text',
  value: 'Some ',
  position:
   Position {
     start: { line: 1, column: 1, offset: 0 },
     end: { line: 1, column: 6, offset: 5 },
     indent: [] } }

// object condition: { value: 'emphasis' }
{ type: 'text',
  value: 'emphasis',
  position:
   Position {
     start: { line: 1, column: 7, offset: 6 },
     end: { line: 1, column: 15, offset: 14 },
     indent: [] } }

// function condition: function (node) { return node.type === 'inlineCode' }
{ type: 'inlineCode',
  value: 'code',
  position:
   Position {
     start: { line: 1, column: 38, offset: 37 },
     end: { line: 1, column: 44, offset: 43 },
     indent: [] } }

API

find(node, condition)

Return the first node that matches condition, or undefined if no node matches.

• node ([Node](https://github.com/wooorm/unist#node)) - Node to search
• condition (string, object or function) - Condition used to test each node. Behaviour depends on the type of the condition:

• string finds first node with a truthy property matching string
• object finds first node that has matching values for all properties of object
• function finds first node for which function returns true when passed node as argument
