InLine

InLine was created to provide a 100% Ruby alternative to the ReadLine library, providing some of its most popular features such as:

• Basic line editing operations
• Word completion
• History Management
• Custom key/key sequences bindings

Installation

The simplest method to install InLine is to install the gem:

        gem install -r inline

Usage

Editor initialization:

        require 'inline'
        editor = InLine::Editor.new

Key binding:

        editor.bind(:ctrl_z) { editor.undo }
        editor.bind(:up_arrow) { editor.history_back }
        editor.bind(:ctrl_x) { puts "Exiting..."; exit }

Setup word completion

        editor.completion_proc = lambda do |word|
                if word
                        ['select', 'update', 'delete', 'debug', 'destroy'].find_all  { |e| e.match(/^#{Regexp.escape(word)}/) }
                end
        end
        editor.completion_append_string = " "

Read input:

        editor.read("=> ")
