pry-pipeline

Pipeline for pry. This adds _pipe_ and | methods to String and Symbol.

Installation

Add this line to your application's Gemfile:

group :development do
  gem 'pry-pipeline'
end

And then execute:

$ bundle

Or install it yourself as:

$ gem install pry-pipeline

Simple usage

This usage is simple but unuseful.

Pipeline to pry's command

$ pry
[1] pry(main)> 'Pry.run_command' | '$'

  options = {
    :context => TOPLEVEL_BINDING,
    :show_output => true,

    :commands => Pry.commands
  }.merge!(options)

  output = options[:show_output] ? options[:output] : StringIO.new

  Pry.new(:output => output, :input => StringIO.new(command_string), :commands => options[:commands], :prompt => proc {""}, :hooks => Pry::Hooks.new).rep(options[:context])
end

Pipeline to ruby block

Pipeline to ruby block from pry's command with pry-command_result

Useful usage(with ruby-anything)

You can select method interactively and see its source!!!

$ pry
[1] pry(main)> 'Pry.' + _anything_(Pry.methods) | '$'
>>>>>>> select method with anything interface >>>>>>>
>>>>>>> select `run_command`                  >>>>>>>

  options = {
    :context => TOPLEVEL_BINDING,
    :show_output => true,
    :output => Pry.output,
    :commands => Pry.commands
  }.merge!(options)

  output = options[:show_output] ? options[:output] : StringIO.new

  Pry.new(:output => output, :input => StringIO.new(command_string), :commands => options[:commands], :prompt => proc {""}, :hooks => Pry::Hooks.new).rep(options[:context])
end
=> nil

Tips

In your ~/.pryrc.(if you use ruby-anything)

begin
  require 'ruby-anything'
  require 'pry-pipeline'
rescue LoadError => err
  puts "Failed to require. in #{__FILE__}"
end

def method_source(obj)
  "#{obj.inspect}." + _anything_(obj.methods) | '$'
end

def instance_method_source(cls)
  "#{cls.inspect}#" + _anything_(cls.instance_methods) | '$'
end

Start pry.

$ pry
[1] pry(main)> method_source Pry
>>>>>>> select method with anything interface >>>>>>>
>>>>>>> select `run_command`                  >>>>>>>

  }.merge!(options)

  output = options[:show_output] ? options[:output] : StringIO.new

  Pry.new(:output => output, :input => StringIO.new(command_string), :commands => options[:commands], :prompt => proc {""}, :hooks => Pry::Hooks.new).rep(options[:context])
end
=> nil
