Setup

$ git clone https://github.com/babel/babili
$ cd babili
$ npm install
$ npm run bootstrap

Then you can either run:

$ npm run build

to build Babel once or:

$ npm run watch

to have Babel build itself then incrementally build files on change.

To run tests:

$ npm test

To run lint:

$ npm run lint

To run lint autofixes:

$ npm run fix

To run current benchmarks on a file:

$ ./scripts/benchmark.js file.js

To run current plugin timing on a file:

$ ./scripts/plugin-timing.js file.js

Releasing

Use npm run publish. It will run lerna publish (we use --independent) so it will prompt the version number for every package.

If you are releasing a new package, you'll want to run ./scripts/npm-owner-update.sh to add all owners to the new npm package.
