I was hoping that I could detect it no matter where it was so advanced users could do symlinks or move it to their own folders or whatever which made me think of bash's which. You're right though, if I'm relegated to typing out the full path might as well use os.path.exists and allow the user to modify the path it looks in with a preference. ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG

Thanks! Nope. If you're doing that, just use os.path.exists() or isfile().

Understandably, I wrote "/usr/bin/which name" and it should be "/usr/bin/which /usr/local/bin/name". Should have included the full path for the argument as well.

Would also be interested if there is a better way of checking to see if a command line utility is currently located in the path for the current user's system. I think what you've done is correct -- i.e. it's not on the PATH for the users system. For the most part, the PATH for the command line is added to the shell rc scripts, so if you are not running from a shell (i.e. from a py2app bundle) you won't have the additional entries on PATH (like /usr/local/bin). I'm pretty sure there is a way to edit a plist somewhere to add to the PATH system (or user?) wide. However, if you're delivering an app bundle, you probably don't want to require your users to do this. I may misunderstand your use case, but I think you could specifically search for the utility in places it might be expected to be found: /usr/bin /usr/local/bin /sw/... (for fink) /opt/... (for macports) rather then expect it to be on the PATH. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig unsubscribe: http://mail.python.org/mailman/options/Pythonmac-SIG
[Pythonmac-SIG] py2app cutomize up-level main.py
Hi there how are you doing? My main.py is up-level in other folder and I would like to know how can I customize the py2app setup script to create a folder on the Resources/folder/main.py and then boot it automatically.

[Pythonmac-SIG] Popen and py2app
py2app experts,
I have a script that is packaged using and py2app that does a
pre-check to see if a command line utility is installed, using Popen
and "which name". (The script downloads and installs it if not.)
I pass subprocess.PIPE for stdout and stderr, with shell=True.
When I run the script "raw" from the terminal it always prints,
correctly, with the path to the desired utility, i.e.
('/usr/local/bin/name', '')
When I run the program after compiling with py2app, exactly as
documented on the website, the console always gets ('', '') as the
response, which is incorrect as it's definitely installed ... nor was
an error reported.
I even tried re-writing the Popen command as "/usr/bin/which name" to no avail.
Using 10.6.5, py2app 0.5.2.
Could this be a problem with py2app, or is there something about the
run-time environment I've overlooked?
Would also be interested if there is a better way of checking to see
if a command line utility is currently located in the path for the
current user's system.
(Just a hobbyist here, go easy on me!)
