iTerm2 on Mac OSX: add alt-left, alt-right and alt-backspace behaviour

posted by Arkham on January 9th, 2013

If you want iTerm2 to behave like the other Mac OSX applications, so that alt + left moves the previous word, alt + right moves to the next word and alt + backspace deletes the whole word, add these keyboard shortcuts from iTerm > Preferences > Profiles > Keys:

  • Alt + left: Send Escape Sequence, Esc + b
  • Alt + right: Send Escape Sequence, Esc + f
  • Alt + backspace: Send Hex Code, 0x17

Ruby 1.9 – Tap my Object

posted by Arkham on October 28th, 2011

Let’ say you need to debug this piece of code:

very_cool_method(egg, sausage)

What would you do? I guess something along the lines of:

spam = very_cool_method(egg, sausage)
p spam

Well, Ruby 1.9 let you do something cooler instead:

very_cool_method(egg, sausage).tap{ |s| p s }

The cool thing about tap is that you can use it to eavesdrop method chains:

very_cool_method(egg, sausage).tap{ |s| p s }.now_make_sandwich_from(bacon)

Hooray! :)

  • Mr. L33T, I may run around in circles when I play halo, and I might never get a monster kill, well, I can’t even find the space bar half the time. But I know when I find true love, and that is worth more than all the uber gear in the world.
  • Too long, did not listen!
