[Pythonmac-SIG] py2app questions..

[Chris Barker - NOAA Federal]

Ronald et al,

As matplotlib seems to be responsible for bringing eveything else in,
I'm trying a different tack:

1) I've removed many of the recipes from my p2app distribution,
notably teh matplotlib one. So now the only recipe getting run is wx.

2) I know that matplotlib isn't going to work right, as there are
issues with matplotlib data, etc. So I've tried to remove it by adding
it to "excludes". However, it's getting included anyway, in the
site_packages zip file. (but doesn't work...)

But moving on...

I"ve added ['matplotlib'] to "packages".

Now I get it included, in full, in Resources/lib/python2.7, and non
longer in the site_packages zip, and the app works fine.

the matplotlib package is 64MB though, so it would be nice to trim it
down, but this isn't bad, and the total package is now 134MB, rather
than the 210MB I did have.

So I suggest that the matplotlib recipe should:

- remove matplotlib from the site_packages zip

- install the matplotlib package in it's entirety (though maybe strip
out the *.py files...., and things like tests, etc.)

- not run matplotlib through modulegraph -- whatever the user is
actually using (numpy, etc) is probably imported elsewhere anyway.
(though maybe including numpy would make some sense...)

I hope this helps others in the future in any case.

-Chris
