I'm new to all this, so apologies if I'm doing something daft. I'm trying to create a MacRuby GUI application to parse a load of information from InDesign documents. I've previously made this application using applescriptObjC, but I was constantly bouncing off the walls of applescript and getting seemingly random bad_exec errors if I ran it too many times without a reboot, so I've decided to try with MacRuby. I'm only at the stage of probing MacRuby to see how to do it, and I've immediately hit a problem; it seems to take a very long time to set up the link to InDesign. I found some code in correspondence between Matt Aimonetti and Spencer Rose that I am using to test: #!/usr/local/bin/macruby framework 'Foundation' framework 'ScriptingBridge' # I followed Matt's instructions for making the bridge support file, but I wasn't sure where it needs to go, so I did this for a quick fix. load_bridge_support_file '/Users/fatboy/inDesign.bridgesupport' appurl = NSURL.fileURLWithPath("/Applications/Adobe Indesign CS5/Adobe InDesign CS5.app") @id = SBApplication.applicationWithURL(appurl) doc = @id.activeDocument puts doc.name pgph = doc.allParagraphStyles pgph.each do |style| puts "#{style.name}" puts style.properties["appliedFont"].name end This code works, but it takes 15+ seconds to set up the link to InDesign (similar stuff with safari takes about 1 second, and in applescript or rb-appscript it takes about a tenth of a second for either InDesign or safari). I also tried SBApplication.applicationWithBundleIdentifier("com.adobe.indesign"), and this was just the same. Is there something I am missing here? Thanks in advance for any help you can offer. Fb
