#fuckitruby

Tired of NameError ? Tired of the lack of AI? Tired of ruby-not-being-a-grammar-nazi?

Fuck it, ruby, that's not what I meant!

def lala(explicit)
  if exlicit
    do_something_stupid
  else
    explicit
  end
end

/home/penka-was-abducted/lala.rb:2:in `lala': undefined local variable or method `exlicit' for main:Object (NameError)
  from /home/penka-was-abducted/lala.rb:9:in `<main>'

ohh

require 'fuckitruby'

def lala...

fix in 'lala': 'exlicit' to 
  'explicit' 				[ENTER]    
  other name 				[type it]
  fix explicit to exlicit 	[!] [ENTER]

# program rewrites itself and reexecutes properly

##faq

• why

  it's fun.

  it's "a program can self-heal itself on error conditions" little experiment

• srsly?

  well it's not for production use , but it combines several really cool hacks

  it looks for the local variables in the offending scope using binding_of_caller,

  it uses lewenstein distance to find the most probable fix, thanks hotwater

  it uses parser to find the exact locations of name uses in the method

  it uses colorize to color the output

• uh it's inspired by magnificient thefuck command

that name sucks

it's an obvious nod to thefuck command.
