broccoli-glob-filter

Base class for broccoli plugins that processes files one by one.

Features:

• It stores results in the cache and rebuilds only changed files.
• It supports glob patterns to specify files to filter.

Install

npm install broccoli-glob-filter

Usage

var Filter = require('broccoli-glob-filter')

var MyFilter = function(inputTree, options) {
  Filter.apply(this, arguments)
}
MyFilter.prototype = Object.create(Filter.prototype)
MyFilter.processFileContent = function(content, relPath, srcDir) {
  return 'content of filtered file'

  // You can return an array, when you need to create more than one file,
  // or to set special path of a file.
  return [
    {
      path: 'path/of/new/file',
      content: 'content'
    }
  ]
}

API

Filter(inputTree, [options])

Constructor.

inputTree

Type: Tree

options

Type: object

List of options

files

Type: array.<string> Default: ['**']

Glob patterns for filtered files.

targetExtension

Type: string

New extension of filtered files.

changeFileName

Type: function(string) -> string

Function that is called for every file with its filename and should return new filename of the filtered file. When this function is specified, option targetExtension doesn't work.

Filter.processFileContent(content, relPath, srcDir)

Returns: string|array.<object>

This method must be implemented in the inherited class. It processes content of each file from the inputTree that matches patterns and returns content of the new file.

If you need to create more than one file, or to set special path of a file, you can return an array of file objects with the following properties:

• path – relative path of the new file.
• content – content of the new file.

If you want to process a file asynchronously, you can return a promise.

content

Type: string

Content of source file.

relPath

Type: string

Relative path of source file.

srcDir

Type: string

Path of the inputTree. You can use it, when you need to read additional files from tree.
