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(“=> ”)
