[matplotlib-devel] Plans for matplotlib py3k/final release (and impact on Debian)

[Sandro Tosi]

Hello,
as you may be aware of, in 1 month (more or less) Debian will freeze,
that means that no new upstream releases will be allowed in the
upcoming release, only fixex for important bugs.

Currently in Debian archive we have 1.1.1rc1 . Recent mails have
mentioned that the next release will be py3k enabled. Well, what are
you're plans to release such version? :)

It would be really awesome to have a python3 matplotlib in Debian, and
i'd be happy to test any new RC you'd like to release.

Cheers,

Just to mention: I've set up a daily builds PPA for matplotlib, and
it's been happily producing Python 3 builds for a while, so it looks
like it should be fairly painless:

My original offer (made several months ago) to help test this on Windows 
still stands :)

Thanks.  Does git master build and pass the unit tests on Windows?

git master builds and tests OK on win32-py2.7.

With the attached patch git master builds and works (in practice) OK on 
win-amd64-py3.2 but there are many test errors of type "RuntimeError: 
Could not open facefile X:\Python32\...\ttf\Vera.ttf; 
Cannot_Open_Resource". I do delete the ~\.matplotlib folder before 
running the tests and can verify that 
FT2Font(r"X:\Python32\lib\site-packages\matplotlib\mpl-data\fonts\ttf\Vera.ttf") 
works.

Re: [matplotlib-devel] switching rc files (and discussion of styles)

[Gökhan Sever]

Hello,

This is a good idea indeed. Especially, when one creates plots for
presentations and papers. Usually, I make ticks, ticklabels, axes labels,
line widths, marker sizes as large as possible (within reasonable limits)
to make them more readable for presentation purposes. However, the same
element sizes don't look very pretty when I create the same plots for paper
or vice versa. The solution is either keep modify two rc files or adjust
one rc file accordingly for each plotting style.

Could the syntax be simplfied a bit? Say rather than using that with
statement and the extra 4 spaces, can it be just a one simple liner like
matplotlib.rcuse(mpl_paper.rc) or matplotlib.rcuse(mpl_presentation.rc)?

I believe that's what the `rc_file` function does in the
PR,
so both use cases are possible. I think it makes sense to allow both.
