Add comments above your Rails actions that look like:

# @route GET /waterlilies/:id (waterlily)
def show
  # ...
end

# @route PATCH /waterlilies/:id (waterlily)
# @route PUT /waterlilies/:id (waterlily)
def update
  # ...
end

Based on your routes.rb file!

Add this line to your Rails application's Gemfile:

group :development do
  gem "chusaku", require: false
end

And then execute:

bundle install

From the root of your Rails application, run:

bundle exec chusaku

Chusaku has some flags available for use as well:

$ bundle exec chusaku --help
Usage: chusaku [options]
        --dry-run                       Run without file modifications
        --exit-with-error-on-annotation Fail if any file was annotated
    -c, --controllers-pattern=GLOB      Specify alternative controller files glob pattern
    -e, --exclusion-pattern=GLOB        Specify controller files exclusion glob pattern
        --verbose                       Print all annotated files
    -v, --version                       Show Chusaku version number and quit
    -h, --help                          Show this help message and quit

If you'd like to use Chusaku as a Rake task, add the following line to your Rakefile:

require "chusaku"
Chusaku.load_tasks

This will then allow you to call:

bin/rake chusaku

To pass flags, pass them like you would from the CLI executable:

bin/rake chusaku -- --dry-run --exit-with-error-on-annotation

Read the blog post explaining how the gem works at a high level: https://nshki.com/chusaku-a-controller-annotation-gem.

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

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, git commits and tags, and push the .gem file to rubygems.org.
