Create Laucher for program from macports

Question

I am running mountain lion (10.8.4) on a MacPro.  I have downloaded the geany editor using macports ("sudo port install geany").  I can start the program from a terminal using the command "geany" or "geany file.py" if I wish to edit the file "file.py" (I program in python).  I am completely new to the Mac world (having come from Ubuntu Linux).  Note that geany uses XQuartz.  I wish to create a laucher app for geany and to make geany the default editor for .py files.  From what I have read applescript is the way to do this, but nothing I do works.  Any suggestions or links or references would be greatly appreciated.  I can write bash and python scripts to launch geany but cannot get beyound that point.  I keep coming across the comment that the applescript rules have changed for mountain lion.

Answer 1

Use Applications -> Automator -> Application -> Run Shell Script
Change the "Pass input"  to "as arguments"
Change the
     echo $f
to the full path to your geany executable.  Leave the $f
     /the/full/path/to/geany $f
Save the Automator app. Give it a name you like.
Now you can use twtwtw' trick to assocate .py files with the Automator app you have just created.
