# finished: a quick script to notify you when a command is done using Mountain Lion notifications
# It grabs the current folder as the title and takes one argument as the message
# Example: make && make install && finished "Done compiling" || finished "compiler failed"
#
# Needs the terminal-notifier gem : `gem install terminal-notifier`
# Can alternately be used with the CLI <https://github.com/alloy/terminal-notifier>
# (remove require block below and swap comment lines at the bottom)

TerminalNotifier.notify(message, :activate => activate, :title => "Finished in #{project}", :sender => "com.googlecode.iterm2")
# %x{/usr/bin/terminal-notifier -message "#{message}" -title "Finished in #{project}" -activate #{activate}}
