Leash

Leash provides a lightweight framework to implement "Do Nothing Scripting" with Ruby.

A "do nothing script" is a script that encodes instructions of a manual procedure and encapsulating each step in a function. Making it easier to start small and gradually increase the level of automation.

Installation

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

$ bundle add leash

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

$ gem install leash

Usage

Define steps for your procedure by Leash::Procedure#step.

require 'leash'

procedure = Leash::Procedure.new("My Procedure") do
  step "Creates a manual step, which only contains a description."

  step "Creates an automated step by providing a block, run: `bundle install`" do
    system("bundle install")
  end

  step "Or by passing a callable object as the second argument, run: `echo Hello!`", -> { system("echo Hello!") }
end

Execute the defined procedure by Leash::Procedure#run.

# Executes each step by pressing `Enter`.
procedure.run

Render a text report by Leash::Procedure#render.

# Renders a text report for the procedure
puts procedure.render

# > My Procedure
# > (1/3): Creates a manual step, which only contains a description.
# > (2/3): Creates an automated step by providing a block, run: `bundle install`
# > (3/3): Or by passing a callable object as the second argument, run: `echo Hello!`

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.
