getting locale working correctly: best practices?

[sandro dentella]

Hi,

using the --onedir option I managed to get to the point that the
application starts, recognizes the locale setting of the os it is
running
on, uses locale .po of my application to translate messages, but
when I
use babel to format numbers, it complains that it does not know the
locale
it_IT.

My understanding is that that locale *is* installed on the machine,
but is
not visible to the application.

Of course I don't mean to add locale for any possible language in my
application, I'd rather use the locale already installed on the os
but
that -in a way- is the opposite of the logic of pyinstaller that
should
provide a complete environ...

How should I do?

Which are the best practices for localization?

thanks again
sandro

I'm not sure I understand the problem. Can you provide me with a
reproduction recipe?

Here a 2 line example:

sandro@bluff:/misc/src/svn/pyinstaller-hg$ cat babex/ex1.py

from babel import numbers
print numbers.format_decimal(123.4)

babel needs to access the locale system to know how to format numbers
It finds it on my machine:

sandro@bluff:/misc/src/svn/pyinstaller-hg$ python babex/ex1.py
123,4

But not on the generated one:

sandro@bluff:/misc/src/svn/pyinstaller-hg$ Makespec.py -o babex babex/ex1.py
wrote babex/ex1.spec
now run Build.py to build the executable
