excerpt

Excerpt

Extracts portion of some input content like String, file, URI, ...

Usage

Excerpt.new('application.html').around_line(12, radius: 2)

from some app gives you this code:

  = csrf_meta_tags
%body
  #navigation
    = render '/layouts/application/nav'
  .container-fixed

You can also request a excerpt from URI:

# radius is omitted here, default value is 4
Excerpt.new('https://github.com/rails/rails/blob/master/railties/lib/rails.rb').around_line(26)

gives you:

module Rails
  autoload :Info, 'rails/info'
  autoload :InfoController, 'rails/info_controller'
  autoload :Queueing, 'rails/queueing'

  class << self
    def application
      @application ||= nil
    end

Installation

Add this line to your application's Gemfile:

gem 'excerpt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install excerpt
