Hello scripters,

After reading the recent posts on rb-appscript I decided to give it a whirl. So I started by just redoing a recent script than came across here and after a little tinkering I got it to work. From there I wanted to try and get the ruby code to run from inside an applescript and this is what I have come up with.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

set rb to "require 'rubygems'

require 'appscript'

include Appscript

require 'osax'

include OSAX

# Set Duration Params

new_duration = 10

# App Declarations

Finder = app('Finder')

QT = app('QuickTime Player.app')

theFile = osax.choose_file()

theMovie = Finder.files[theFile].name.get

savePath = osax.choose_folder()

QT.open(theFile)

QT.select_all(theMovie)

QT.documents[theMovie].selection_end.set(new_duration * (QT.documents[theMovie].time_scale.get))

QT.documents[theMovie].trim

QT.documents[theMovie].save_self_contained(:in => (String(savePath) + '/' + theMovie))

QT.documents[theMovie].close"

set theCommand to "ruby -e \"" & rb & "\""

do shell script theCommand

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Here's where I get lost though. If I copy the contents of theCommand and paste it into a terminal window the script runs fine. However when it's ran via the do shell script theCommand I get back this error

-e:1: syntax error, unexpected tIDENTIFIER, expecting $end

require 'rubygems'
