broccoli-merge-trees

Copy multiple trees of files on top of each other, resulting in a single merged tree.

Installation

npm install --save-dev broccoli-merge-trees

Usage

var BroccoliMergeTrees = require('broccoli-merge-trees');

var mergedNode = new BroccoliMergeTrees(inputNodes, options);

• inputNodes: An array of nodes, whose contents will be merged

• options: A hash of options

Options

• overwrite: By default, broccoli-merge-trees throws an error when a file exists in multiple nodes. If you pass { overwrite: true }, the output will contain the version of the file as it exists in the last input node that contains it.

• annotation: A note to help tell multiple plugin instances apart.

Example

If this is your Brocfile.js:

var BroccoliMergeTrees = require('broccoli-merge-trees');

module.exports = new BroccoliMergeTrees(['public', 'scripts']);

And your project contains these files:

.
├─ public
│  ├─ index.html
│  └─ images
│     └─ logo.png
├─ scripts
│  └─ app.js
├─ Brocfile.js
…

Then running broccoli build the-output will generate this folder:

the-output
├─ app.js
├─ index.html
└─ images
   └─ logo.png

The parent folders, public and scripts in this case, are not included in the output. The output tree contains only the files within each folder, all mixed together.

npm install
npm test

Issues and pull requests are welcome. If you change code, be sure to re-run npm test. Oftentimes it's useful to add or update tests as well.
