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 package [file.js]
# do not remove package after installing to node_modules
$ ./scripts/benchmark.js package [file.js] --offline

To run current plugin timing on a file:

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

Releasing

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 after releasing. Or do it manually via https://www.npmjs.com/package/package-name-here/access.

If you need to update deps run npm run clean and then npm run bootstrap.

To get the changelog, run npm run changelog to print to the terminal.

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