Typo in mplconf

Development matplotlib-devel
1

Hello,

I came across a typo in mplconfig.py that results in an error when processing the matplotlib configurations. Attached is a patch.

I can apply this patch because it is a simple fix, but the larger
question is whether we want to distribute/support the traited config
at all. It seems like this development branch is mostly abandoned.
Any comments Darren, or others?

But in any case as long as we *do* currently have it it is good to fix
these bugs, so thanks for the patch.

The traited config stuff was never supported, and has to be turned on
by setting a global in the source code. So I don't think it makes
sense to distribute it. I'm too busy these days to try to support this
feature and make it the default, plus there were issues with
additional overhead due to pkg_resources, traits, and configobj. I
wouldn't be offended if the code was removed from the trunk. (sniffs)

Thanks for applying that patch. I should also note that I am still in the process of tracking down another bug that seems to be related to tconfig. One can trigger it using the pydoc utility on a local build and install of matplotlib from svn. An exception gets raised when searching for “mpl_toolkits.mplot3d.axes3d” from the pydoc graphical gui, which seems to do a brute-force examination of the documentation. So it might be triggering unmaintained code.

Do you guys still want a bug report for the tconfig issue, just in case it might be related to Traits in general (I have no clue where the issue is happening)?

After some more digging, I think I finally found the source of my issues. I have noticed that there are inconsistencies between the keys and sections listed in the default matplotlib.conf file and in the class MPLConfig(). While in most cases, these inconsistencies are innocuous and do not cause errors, I think there have been a few inadvertent mistakes.

So, I modified one of the programs to produce a list of all the inconstancies that exist, and I will let you guys figure out what needs to be fixed, or what is intentional.

For example, the first item in thee file states that the MPLConfig class do not have the keys “numerix” and “maskedarray”, but the default configuration file does. In addition, the MPLConfig class has the key datapath, but that is not given in the default conf file. (I do recognize that this should probably be expected in this case, I am merely explaining how to interpret the attached file).

The next paragraph states that MPLConfig class defines a section “path”, but it is not found in the default configuration file.

The other lines that I find interesting:
15 (‘preview’ is given in the conf file, but not in the class)

31-32 (‘embed_chars’ is in the default file, but the config class has ‘embed_char_paths’)
35-36 (many keys between the class and the file are similar, but not the same)

The other paragraphs might be interesting, but I hardly know enough to make such determinations.

Ben,

With Darren's permission I went ahead and deleted matplotlib.config from svn (r8495), so it will not appear in the next release unless someone resurrects it. It can always be pulled out of the svn history and updated, if that turns out to be the thing to do. For now, though, I think that it is better to simplify the mpl tree when possible. We have enough work to do to maintain and improve the parts of mpl that are being used.

Eric,

No problem, I just noticed that the config directory was removed. And I just discovered that when svn deletes a directory full of .py and pyc files, the .pyc files get left behind and are still accessed by programs like pydoc that walks the directories searching for packages to load.

Anyway, I am more than happy to help prune down the trunk. Extra stuff that isn’t being used just add noise and confusion. Especially to a depth-first debugger like myself…
