Maybe You Meant

May You Meant is an IRB extension that guesses the method you meant to call when you make a typo.

Say for example you call 'hello world'.ucase Maybe You Meant will output Maybe you meant: 'hello world'.upcase and automatically call the correct method and insert the new line into your IRB history.

Installation

gem install maybeyoumeant

The rainbow gem is installed for color console output.

Put the following into you .irbrc require 'rubygems' require 'maybeyoumeant'

Configuration

To turn off logging

MaybeYouMeant::Config.debug = false

To not automatically call methods

MaybeYouMeant::Config.call_nearby = false

To not add an updated line to IRB history

MaybeYouMeant::Config.add_to_history = false

To remove the incorrect line from IRB history

MaybeYouMeant::Config.remove_from_history = true

How It Works

Object is monkey-patched to intercept NoMethodErrors. Levenshtein distances are calculated for other methods on the object, and the closest one is selected and called.
