I'm trying to achieve what seems to me like a simple goal: being able to run Python scripts easily from within TakeCommand v10.00.57. I tried using the internal scripting support, but that causes crashes about which I've posted elsewhere at http://jpsoft.com/forums/showthread.php?t=1031 My next step was to use an external interpreter, and I found that to work. The one annoyance was that I couldn't get TakeCommand to tab-expand script names as executable commands. After looking through the help, it seemed the PathExt variable might be what I wanted, so I tried enabling that via the OPTION command. As soon as I do that, though, TakeCommand stops processing the tcstart.btm file in its program folder. What seems simple is turning out to be surprisingly unpleasant.
