rbs-src

rbs-src helps editing RBS files with rbs collection.

The workflow

rbs-src helps editing RBS files by having git repositories for each gems and making symlinks to the repositories.

Assume you have a rbs collection setup loading activesupport-7.0 and sidekiq-6.2. Running the rbs-src setup will make repositories and symlinks as the following:

- (Repository root)
  - Gemfile and other files
  - rbs_collection.yaml
  - rbs_collection.lock.yaml
  - tmp/rbs-src
    - activesupport-7.0               (a working copy of https://github.com/ruby/rbs_gem_collection.git)
      - gems/activesupport/7.0/*.rbs  (RBS files for activesupport-7.0)
    - sidekiq-6.0                     (another working copy of https://github.com/ruby/rbs_gem_collection.git)
      - gems/sidekiq/6.2/*.rbs        (RBS files for sidekiq-6.2)
  - sig/
    - **/*.rbs                        (RBS files for your Ruby program)
    - rbs-src/activesupport-7.0       (Symlink to /tmp/rbs-src/activesupport-7.0/gems/activesupport/7.0)
    - rbs-src/sidekiq-6.2             (Symlink to /tmp/rbs-src/sidekiq-6.2/gems/sidekiq/6.2)

The project structure allows the following workflow:

1. You can edit the RBS files of rbs collection directly through sig/rbs-src/*/**.rbs
2. Your changes are detected by Steep and used to type check your Ruby program code
3. You can push your changes to upstream through the git repositories under tmp/rbs-src

Installation

$ gem install rbs-src

Usage

rbs-src setup

Load gem dependencies from rbs_collection.lock.yaml and set up all repositories and symlinks.

$ rbs-src setup

If the git repository content is edited, it runs git stash and git reset --hard.

It accepts --output option to write the dependencies to a file.

$ rbs-src setup --output

You can load the dependencies to your type checkers from the file.

For Steep users

The recommended setup for Steep is the following:

# Steepfile

target ... do
  # Existing config...

  # Assume we use `rbs-src setup --output` to generate `rbs_src.dep` file
  if (dep_path = Pathname("rbs_src.dep")).file?
    # Stop loading libraries through rbs-collection
    disable_collection()

    signature "sig/rbs-src/*/*.rbs"
    signature "sig/rbs-src/*/[^_]*/**/*.rbs"

    dep_path.readlines().each {|lib| library(lib.chomp) }
  end
end

In this setup, you can use Steep without using rbs-src until you run rbs-src setup --output. Once you run rbs-src setup --output, it generates rbs_src.dep file and Steepfile loads the dependencies from the file.

# When you install your rbs_collection dependencies
$ rbs collection install && rbs-src setup --output

# When you update your rbs_collection dependencies
$ rbs collection update && rbs-src setup --output

# When you stop using rbs-src
$ rm -rf rbs_src.dep tmp/rbs-src sig/rbs-src

rbs-src link

The command clones and set up a symlink of a ruby gem, not loaded from rbs_collection.lock.yaml.

$ rbs-src link https://github.com/ruby/gem_rbs_collection.git active_emoji 0.0

This is typically useful for adding new gem to one of the collections. The command will clone the git repository for active_emoji-0.0 and make a symlink to non-existing directory. You can add directories in the repository for active_emoji-0.0 and start writing RBS files through the symlink. Once you finished the edit, you can push the RBS files to upstream!

rbs-src status

The command checks the status of all git repositories.

$ rbs-src status
[ok] activesupport tmp/rbs-src/activesupport-7.0
[dirty] rainbow tmp/rbs-src/rainbow-3.0
[commit_mismatch] ast tmp/rbs-src/ast-2.4

You may want to delete the repositories to reset, but use this command to ensure you don't have uncommitted changes. (Note rbs-src status doesn't check if you pushed the commits to remotes.)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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 the created tag, and push the .gem file to rubygems.org.
