Right, this was my working assumption when I made the 'with' statement
suggestion. Since it's a new feature, it won't make it into the 1.1.x
series, and in the next  major relase (>= py2.6) we can safely use
context managers.

The numpy requirement is whichever one introduced no.nextafter(). I beleive
that is 1.4.

It is at least 1.4; see this thread:

The minimum requirement of the 1.1 series is still Python 2.4, believe 
it or not, though I'm not sure practically what the minimum numpy is.

The next major release (which will include Python 3 support) bumps the 
minimum requirement up to Python 2.6.

Thanks for pinging me on the PR, Paul. Both the original PR and the
addition of the context manager are great ideas.

Just to clarify, what I implemented in mpltools was a sort-of stylesheet
that can be easily accessed (i.e. you don't have to remember the path, just
the name; and if you forget that, it's listed in a module attribute). But,
I ended up using ConfigObj to parse the rc file instead of using
matplotlib's parser. One major disadvantage of that approach is that
ConfigObj uses a different syntax than matplotlib's rc parameters. In this
sense, the PR would help greatly to fix this discrepancy.

Unfortunately, the PR doesn't completely fulfill my needs. I wanted to
allow multiple stylesheets to be declared in a single file; this means I'd
need to plug into the loop that iterates over the lines of the file. I can
push in that direction on the PR, but I don't want to do that unless people
think this would be more-generally useful.

You will need Python 2.5 or later to use the 'with' statement.  I think
that is already a requirement of matplotlib, and this page--which says
2.4--is not up to date:
    http://matplotlib.sourceforge.net/users/installing.html
I'm sure the minimum version of numpy given there (1.1) is also wrong.

Such a feature would clean up the test code considerably.

Hey everyone,

I wanted to highlight Matthew Emmett's (memmett) PR in progress [1] that
brings the ability to switch between rcParams.

Matthew's implementation started with just being able to read in and use
an rcParam file, and I suggested the idea of having a context manager,
that would allow you to do something like:

  with rc_context(fname):
      plt.plot()
      ...

and have the rcParams restored outside of the context.

I know there have been a few threads (can't find links now for some
reason) and in-person discussions in the past about having this kind of
ability in matplotlib, and having an idea of "styles", and Tony Yu
implemented a variant of this on top of matplotlib in mpltools [2], but
I wanted to ping the list here for other ideas and feelings about such
functionality (if anyone can find pointers to previous discussions, that
would be very welcome).
