[Pythonmac-SIG] How to detect in a Cocoa app if Python is available?
Thu, 02 May 2002 10:00:38 +0200 (CEST)
I'm writing some Cocoa front-ends to Python apps and wonder what is
the best way to detect if Python is available on a target OS X box?
If not I'm popping up an Alert panel so you can download Python with
First I tried a popen() on "which python", but that runs into some
shell problems due to environment variables, I assume. So, for now
I'm expicitly indicating "usr/local/bin/python" and make a C-popen()
on a bundled dummy Python file (using usr/local/bin/python) writing
just "Hello World" which I compare the output of popen() with.
This is not really satisfactory and I wonder if anybody did better
than this? Note, that I'm using vanilla Python 2.2 built from the
sources with configure/make, so there is no Python.framework stuff
involved. I also wonder if this would this make things easier and
how, if so?
I can send some C/Objective-C code if anybody is interested.
