Hi,
I have put this in my code :
env = os.environ.copy()
if sys.platform == 'darwin' and 'LC_ALL' not in env:
env['LC_ALL'] = 'en_US.UTF-8'
and now I use Popen like this :
Popen(mycommand, env = env)
Maybe it's a little less suboptmal then changing user's environment :)
But it's not a definive solution cause I'm forcing a locale and I'm not
sure it will work in every context... Time will say :)
Thank you for your help
Pierre

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.
The startup binary voor pyapp forces LC_CTYPE to en_US.UTF-8 during the call to
Py_Initialize, and resets it to whatever it was before afterwards. This is
primairly done to ensure a sane I/O encoding when using Python 3 (that is, for
the '.UTF-8' bit).
I can only test with 10.6 in a virtual machine, I should have some time later
this week to do so (in particular to check what locale related environment
variables are set automaticly there and to find why --emulate-shell-environmet
doesn't pick those up).
You can force the right settings by setting them yourself in your python script
(os.environ['LC_CTYPE'] = 'fr_FR.UTF-8', etc., etc., before calling
subprocess.Popen). That's suboptimal, but should at least give you a working
program without changing all R scripts.

Hi all,
I have create a .app with py2app for a wxpython application. 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.
This is happening with python 2.7.2, wxpython2.9, py2app 0.7.3 under Mac OS X
10.6.8.
What am I missing ?
I'm not sure. What kind of encoding error occurs? The exact error message might
give a hint as to what's going on here.
What's really strange is that double-clicking the app does not have the same
behavior as calling the open command, I'd expect that those would be behave the
same.
Do you have a shell environment variable in your shell's profile
(.profile/.bash_profile/...) that is needed by the other program? 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.
Ronald
