Rake Task

You can define a Rake task for Minify. Please write the following code in your Rakefile:

# Rakefile
require 'minifyrb/rake_task'
Minifyrb::RakeTask.new

The task rake minifyrb will be defined:

$ bundle exec rake -T
rake minifyrb                 # Minify Ruby files in the current directory and subdirectories

Ruby API

From Ruby code, use Minifyrb::Minifier#minify API:

require 'minifyrb'

source = <<~'RUBY'
  def say(name)
    puts "Hello, #{name}!"
  end
RUBY

Minifyrb::Minifier.new(source).minify # => "def say(name)puts\"Hello, \#{name}!\";end\n"

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