A Cocoapods plugin for automatically generating Bazel BUILD files

Primary LanguageRubyApache License 2.0Apache-2.0

Cocoapods::Bazel

Cocoapods::Bazel is a Cocoapods plugin that makes it easy to use Bazel instead of Xcode to build your iOS project. It automatically generates Bazel's BUILD.bazel files. It uses rules_ios so you need to set up the WORKSPACE file following the instructions in the README.

⚠️ This is alpha software. We are developing this plugin in the open so you should only use it if you know what you are doing and are willing to help develop it.

Installation

Add this line to your application's Gemfile:

gem 'cocoapods-bazel'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cocoapods-bazel

Usage

This plugin will run extra steps after post_install to generate BUILD.bazel files for Bazel.

To enable the plugin, simply add the following section to your Podfile

plugin 'cocoapods-bazel', {
  rules: {
    'apple_framework' => { load: '@build_bazel_rules_ios//rules:framework.bzl', rule: 'apple_framework' }.freeze,
    'ios_application' => { load: '@build_bazel_rules_ios//rules:app.bzl', rule: 'ios_application' }.freeze,
    'ios_unit_test' => { load: '@build_bazel_rules_ios//rules:test.bzl', rule: 'ios_unit_test' }.freeze
  }.freeze,
}

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Experimental Features

There are some experimental features that are opt-in and can be enabled adding the plugin to the Podfile. Some of these features intentionally break the contract with the .podspecs specification in order to create BUILD files that are easier to maintain and/or evolve using Bazel features that don't have a direct relationship with what cocoapods does. You'll find the keys to enable such features and a brief explanation/motivation for each in Bazel::Config::EXPERIMENTAL_FEATURES (lib/cocoapods/bazel/config.rb).

Note that tests for the experimental features are located under spec/integration/experimental_features and these should mostly replicate the tests under spec/integration/monorepo but with the features on. Also it's a place to create tests specific to a experimental feature that not necessarily will affect the default usage of cocoapods-bazel.
