update py-chaco and related enthought ports

[jjstickel (Jonathan Stickel)]

Patches to update py-chaco, py-enable, py-blockcanvas, py-etsdevtools, and py-scimath to current release versions will be attached.

Documentation for these are sparse, but from what I can tell, wx or qt4 is needed as a backend for py-enable (similar to py-pyface). I have copied over the relevant variant lines from the py-pyface portfile. As wx is still not working well, pyqt4 or pyside are currently the options. Also, it seems that the existing patches are not longer needed.

I have tested basic functionality by importing the modules in a python shell and plotting something via chaco.

May I suggest using wxwidgets as the variant name rather than wx?

In case that support for version 2.8 is needed we could have both wxgtk28 and wxwidgets30, but if it's feasible to fix the problems, it might be easier to fix the problems than to keep the wxWidgets' legacy around.

Sure, wxwidgets can be used for the variant name. At this point, my thought is to just leave it commented out. If there are no bug reports or complaints, I would like to remove the wxwidgets variant entirely at some point in the future.

You don't need to do it now, but next time please at least manually change

into

--- Portfile.orig
+++ Portfile

or something similar to make it more straightforward to apply the patch. Alternatively you could checkout the port from SVN repository, modify it and run svn diff.

For example:

svn co --depth=empty https://svn.macports.org/repository/macports/trunk/dports/ macports
cd macports
svn co --depth=empty python
cd python
svn co py-enable
svn co py-chaco
...

cd py-enable
# do the necessary changes
svn diff

Did you try py-enable with wxWidgets at all?

I'm asking because it doesn't seem that the port is able to find an existing wxWidgets installation at all.

Or at least this is what gets reported:

py-enable committed in r115805.

(PS: I added the wxWidgets PortGroup which doesn't do anything if you don't ask for anything, but this way it is a lot easier to find all the wxWidgets dependents. If you decide to avoid the option altogether, please remove that PortGroup as well. I also added the link to the two relevant tickets.)

py-chaco committed in r115807.

py-scimath committed in r115808.

It is complaining about the deprecated api (warning only), but I guess you are aware of that?

It worked for me today with wxpython-3.0.
