  It seems to be mac specific (which is annoying, as I don't have access to a mac :-/). I tried this on Windows + Ruby 1.9.1 and it works:

  
  D:\>irb
  irb(main):001:0> require 'rawline'
  => true
  irb(main):002:0> Rawline.readline ">> "
  >> testing...
  => "testing..."
  irb(main):003:0>
  

  However, I found a bug in the rawline_irb example. Could you please try to execute the following rawline examples on your system and tell me if they work?

  • rawline_shell.rb
  • raweline_irb.rb
  • readline_emulation.rb
  • key_tester.rb

  They are in the /examples folder of the rawline gem (or here)

  Thanks a lot for the gists!

  I have absolutely no idea why this won't work on Mac with Ruby 1.9.1, considering it works with Ruby 1.8.7!

  My guess (and it's a wild guess...) is that the get_character method (defined in HighLine::SystemExtensions, which RawLine depends on) doesn't seem to be able to do its job for some reason (it returns nil or something similar, instead of the character's ASCII code, maybe?).

  Could you please try to install the Termios library (http://raa.ruby-lang.org/project..., and see if things improve?

  I'm terribly sorry for not being able to do any testing myself, but I don't own a Mac... so well, patches are more than welcome!

  Still no improvements though I installed the latest version arika-ruby-termios (0.9.5) (the previous termios (0.9.4) didn't even want to install)

  OK, then could you try the following:

  
  irb(main):001:0> require 'highline/system_extensions'
  => true
  irb(main):002:0> include HighLine::SystemExtensions
  => Object
  irb(main):003:0> get_character
  

  At this point you press a key, and IRB should print the corresponding ASCII character. If it doesn't, then we have a problem...

  Wow, I think you nailed it - http://gist.github.com/81820

  In ruby 1.9 method 'get_character' returns not a corresponding ASCII character but a character itself :-(

  Well done!!

  Then all you have to do is converting the two get_character() calls in editor.rb to:

  
  get_character(@input).ord rescue nil
  

  ...then everything should work (except the rawline_irb example, but that's another quick fix: see #11).

  I'll push the changes to the central repo tomorrow evening. Thanks a lot!
