[Pythonmac-SIG] py2app : strange behavior maybe relative to encoding

[Pierre Ratinaud]

Hi,

The only message I had was in Console. The software I'm using with Popen 
(R) is complaining (in french) about encoding in my script.

My tests and googling leave me to the conclusion that it is an 
environment problem :
in the working cases, locale.getpreferredencoding() give me fr_FR.UTF-8 
but when double-clicking on the app it gives me us_US.ASCII.
In R, Sys.getlocale() give me :
"LC_CTYPE=fr_FR.UTF-8;LC_NUMERIC=C;LC_TIME=fr_FR.UTF-8;LC_COLLATE=fr_FR.UTF-8;LC_MONETARY=fr_FR.UTF-8;LC_MESSAGES=fr_FR.UTF-8;LC_PAPER=C;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=fr_FR.UTF-8;LC_IDENTIFICATION=C"
and just
"C" when double-clicking.
This happens with or without --emulate-shell-environment
So environment (locale) is not set when double-clicking on app. Also, 
setting locale in my R script resolves the problem, but it's not a 
solution in my case (a lot of R script to change). I am about to test 
setting locale in python (with the env option of Popen), but I need to 
reboot in OS X : )
Thanks for your help.
Regards
Pierre

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.
