Shufu

Shufu is a simple command line generator.

Add this line to your application's Gemfile:

gem 'shufu'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install shufu

require "shufu"

schema = {
  git: {
    commit: {
      amend: :flag,
      author: :equal
    }
  }
}

command = Shufu::Command.new(schema)

p command.to_s({ amend: true, author: "cc-kawakami" })

# => "git commit --amend --author=cc-kawakami"

Hash value means that the key is a command.

{
  git: {
    #...
  }
}

:param value means that the key is parameter.

{
  git: {
    add: {
      path: :param
    }
  }
}

:flag value means that the key is flag argument like --key. When the input is true then the flag argument is output.

{
  git: {
    commit: {
      amend: :flag
    }
  }
}

:equal value means that the key's value is expected to set with = like --key=value.

{
  git: {
    commit: {
      author: :equal
    }
  }
}

:space value means that the key's value is expected to set with space like --key value.

{
  git: {
    commit: {
      author: :space
    }
  }
}

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 the created tag, and push the .gem file to rubygems.org.
