A simple ruby script to add to a TextMate bundle that aligns PHP key/value pairs.

gistfile1.rb

#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -wKU
# Author: Rheinard Korf

# Usage:
# * Create a new bundle (or add to existing bundle).
# * Create a new command (e.g. KeyValue Alignment) and set a shortcut key (e.g. Ctrl+Cmd+Option+] )
# * Paste the code in the command editor and save the bundle (Cmd+S)
#
# Now select a set of key/value pairs (not the whole array) and try out the new command.

lines = ENV['TM_SELECTED_TEXT'].split("\n")

max_length = 0

lines.each do | line |
  temp = line.split(/\:|\=\>/)
  if temp[0].length > max_length then max_length = temp[0].length end
end

lines.each do | line |
  temp = line.split(/\:|\=\>/)
  print temp[0].ljust(max_length) + '=>'
  puts temp[1]
end

Turns this:

"key1" => "value1",  
"longerkey2" => "value2",  
"anevenlongerkey3" => "value3",  
"alongkeykey4" => "value4",  
"nottoolongkey5" => "value5",  

into this:

"key1"             => "value1",  
"longerkey2"       => "value2",  
"anevenlongerkey3" => "value3",  
"alongkeykey4"     => "value4",  
"nottoolongkey5"   => "value5",
