Orthoses

Orthoses is a framework for RBS generation. The Rack architecture keeps your code organized and extensible.

• You can choose which middleware to use.
• You can write your own middleware to use.
• You can publish your middleware and share it with the world.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add orthoses

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install orthoses

Usage

For example, You can write script in Rakefile.

require 'orthoses'

namespace :rbs do
  desc "build RBS to sig/out"
  task :build do
    Orthoses::Builder.new do
      use Orthoses::CreateFileByName,
        base_dir: Rails.root.join("sig/out"),
        header: "# !!! GENERATED CODE !!!"
      use Orthoses::Filter do |name, _content|
        path, _lineno = Object.const_source_location(name)
        return false unless path
        %r{app/models}.match?(path)
      end
      use YourCustom::Middleware
      use Orthoses::Mixin
      use Orthoses::Constant
      use Orthoses::Walk,
        root: "Foo"
      run -> {
        # load library or application
      }
    end.call
  end
end

Then, you can see the result files under sig/out.

Utils

Orthoses::Utils is a collection of useful methods.

Orthoses::Utils.each_const_recursive

Yield const by recursive.

Orthoses::Utils.rbs_defined_const?

Checks if the const name is already defined.

Orthoses::Utils.rbs_defined_class?

Checks if the class name is already defined.

Orthoses::Utils.rbs_environment

Fetch cached RBS::Environment.

Orthoses::Utils.object_to_rbs

Convert Ruby object to RBS string.

Orthoses::Utils.module_name

Get true module name by Module.instance_method(:name).bind(mod).call.

Middlewares

Orthoses::Constant

Add constant signature to class/module. Signatures are predicted from constant values.

Orthoses::Attribute

Add attr, attr_accessor, attr_reader and attr_writer to output RBS. All type set untyped.

Orthoses::Mixin

Add module include/extend/prepend definition.

Orthoses::ObjectSpaceAll

Add module/class by ObjectSpace.each_object(Module)

Orthoses::CreateFileByName

Separate directories for each module name and output RBS files.

Orthoses::Filter

Filter stored value by name and content.

Orthoses::PP

Debug pring current stored values

Orthoses::LoadRBS

Load RBS from paths. And loaded RBS will write to output.

Orthoses::Walk

Load class/module recersive from root constant. If set String to root, It get constant after loading.

Orthoses::Tap

Get the current store in the block as an argument. This is very useful for middleware development and debugging.

Orthoses::DelegateClass

If a class is defined using the DelegateClass method RBS is automatically generated as inherited.

.rb

class Tempfile < DelegateClass(File)
end

.rbs

class Tempfile < File
end

Orthoses::Writer

Write output RBS to io option object. io should be able to call #write method. This is useful when you want to combine outputs into a single output.

Orthoses::RBSPrototypeRB

Run rbs prototype rb command process to paths option files. content_filter option could filter with content decl. mixin_filter option could filter with mixin(include, extend, prepend) decl.

Orthoses::RBSPrototypeRuntime

Run rbs prototype runtime command process with patterns option string.

Orthoses::Autoload

Force load const defined by autoload.

Orthoses::Sort

Sort signatures by class/module.

Orthoses::Trace

Trace the argument and return value objects when the method is actually called and determine the type.

Development

After checking out the repo, run bin/setup to install dependencies. 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.
