[Pythonmac-SIG] Query Regarding IDE for python for GUI Apps

Wed Feb 20 15:53:26 CET 2013

TextMate is a mac text editor which has a number of features that I like because they reduce the number of keystrokes, including search and replace within projects.

I am about to test setting locale in python (with the env option of Popen), but I need to reboot in OS X : )

The resulting app does not work as expected if I double click on it (it works but somewhere in the process, an encoding problem appear from another program called with os.popen). This problem does not occur if I launch my app directly with python, it does not occur if I launch the app by double-clic on myapp inside the .app and it does not occur if I open the .app from a terminal with the "open" command.

Those definitions aren't seen by applications launched through the Finger because the Finder doesn't read the shell's profile.   You could try to use " python setup.py py2app --emulate-shell-environment" to build the app bundle, that activates a hack that does try to read the shell environment.
