Basic library for making interactive command-line applications much easier.


  • Easy way to add commands and help info to them so it can be shown to user.
  • Auto-completion for commands.
  • Command aliasing.



`gem install cli-console`


This library doesn't have any dependencies. Well actually there's no direct dependencies. But in reality need HighLine and Readline. Then why I said there's no dependencies? Because CLI::Console will accept any IO class with implements those few functions which currently are provided by HighLine.

Usage Example

Take a look at examples/shell.rb


YARD with markdown is used for documentation (redcarpet required)


RSpec and simplecov are required, to run tests just rake spec code coverage will also be generated
