# Metamask Plugin [![Build Status](https://travis-ci.com/MetaMask/metamask-plugin.svg?token=3txzDGFpqQqvRCdgwTJp&branch=master)](https://travis-ci.com/MetaMask/metamask-plugin)

## Development

```bash
npm install
```
### Developing with Gulp

We're using an experimental version of `gulp-cli`, so if you have the old version of gulp, you'll need to uninstall it, `npm uninstall -g gulp`, and install this one instead:

```bash
npm install gulpjs/gulp-cli#4.0 -g
```

After that, you can just:
```bash
gulp dev
```

### In Chrome

Open `Settings` > `Extensions`.

Check "Developer mode".

At the top, click `Load Unpacked Extension`.

Navigate to your `metamask-plugin/dist` folder.

Click `Select`.

You now have the plugin, and can click 'inspect views: background plugin' to view its dev console.

### Developing the UI

To enjoy the live-reloading that `gulp dev` offers while working on the `web3-provider-engine` or other dependencies:

 1. Clone the dependency locally.
 2. `npm install` in its folder.
 3. Run `npm link` in its folder.
 4. Run `npm link $DEP_NAME` in this project folder.
 5. Next time you `gulp dev` it will watch the dependency for changes as well!

### Running Tests

Currently the tests are split between two suites (we recently merged the UI into the main plugin repository).  There are two different test suites to be concerned with:

Plugin tests, `npm test`.
UI tests, `npm run testUi`.

You can also run both of these with continuously watching processes, via `npm run watch` and `npm run watchUi`.

#### UI Testing Particulars

Requires `mocha` installed. Run `npm install -g mocha`.

You can either run the test suite once with `npm testUi`, or you can reload on file changes, by running `mocha watch ui/test/**/**`.

### Deploying the UI

 You must be authorized already on the Metamask plugin.

 0. Update the version in `app/manifest.json` and the Changelog in `CHANGELOG.md`.
