I'd be interested to see what you've come up with, if you care to share. I've been thinking about something like this as well. Exemaker, for me, is the wrong solution, because it requires making an .exe file for every script you want to run this way. What I've been thinking about is to write a single executable that gets associated with .py and .pyw (instead of python.exe itself). This executable would parse the #! line to look for a specific python version, or use a configured default if none found (or a parsing error occurs). It would then invoke the appropriate python version (with whatever arguments, if any, are supplied). As far as I can see, this allows both typing the script name and arguments (i.e., without python31 before it) from a command prompt, and doubleclicking on a .py or .pyw file from windows explorer. In both cases, the proper python executable would be used to run the script. What's been holding me back so far is that probably needs to be written in C, to prevent the Python runtime's startup overhead. I haven't written any significant amount of C code in years, if not decades, so that seems like a daunting task to me at the moment. ;-) Gertjan. -- http://mail.python.org/mailman/listinfo/python-list
