Jello
Because everybody likes "paste & jello" sandwiches, right? I know I did when I was a kid.
Jello is a simple library to watch the OS X pasteboard and do something on every paste.
require 'jello'
Jello::Mould.new do |paste|
system "say 'You pasted #{paste}'"
end
Jello.start!
For example, to watch for URLs copied, and then shorten the URL and replace the long URL with the shortened one, write a short mould like the following:
require 'open-uri'
require 'jello'
Jello::Mould.new do |paste|
if paste =~ %r{^http://.*}
uri = $&
uri.gsub! /#/, '%23'
unless uri =~ %r{^http://bit.ly}
shortener = 'http://bit.ly/api?url=' + uri
open(shortener).gets.chomp
else
nil
end
end
end
Jello.start! :verbose => true
Moulds can even be stacked:
require 'jello'
Jello::Mould.new do |paste|
paste += '123'
end
Jello::Mould.new do |paste|
paste += '456'
end
Jello.start! :verbose => true
Jello also provides a binary - if you have some moulds you use often, you can
throw them in your ~/.jello/
folder (as .rb files), and then run jello with
them:
# Assuming ~/.jello/ contains foo.rb, bar.rb, and gaz/{one,two}.rb
$ jello foo bar gaz
# Now foo.rb, bar.rb, one.rb, and two.rb would be executed on incoming
# pastes
Finally, you can use pasteboards other than the general one (see man pbcopy
for more information about this):
require 'jello'
Jello::Mould.new do Jello::Pasteboard::Find |paste|
paste.gsub! /abc/, 'def'
end
Jello.start!
