I would say, rather, that Kiva supports wxWidgets on Windows, GTK, and
Carbon. The support for Cocoa (non-wxWidgets) on the Mac needs a small
addition that I've never gotten around to (it used to work, but I
requested and received a change in PyObjC to support it better, but I
then promptly failed to update Kiva to match).

I'm also not sure that calling it a DisplayPDF 2D drawing engine is
entirely accurate or, indeed, meaningful, but it's probably close
enough.

Sure, I'm not particular about the name.  If ETS is fine with
everyone, then go right ahead.

Ahh, the new code.enthought.com layout is very pretty.  I'll modify
the announce suitably.

Thanks for the changes!

I noticed that I was emphasizing "scientific", but did not realize it
had gotten that bad. ;-D

Thanks and happy new year!

I have no clue, I just stole that whole paragraph from the wiki (and
added the "2D" before the "drawing engine")! 

I'll incorporate your changes as well and send this off sometime
today.  Thanks!

Just FYI, TVTK is not just for scientific/engineering apps.  VTK is a
general graphics/imaging/visualization library.  TVTK does have some
science friendly modules like mlab but that is just a small module
compared to TVTK itself.  For example you can read, write, manipulate
images with TVTK without even creating a window.  So it is more
general purpose than I use it for.  Anyway, I've categorized TVTK
under "graphics".  However, I've retained the ordering of the various
modules.

You might also want to update the Enthon page while you are at it.
The versions of various packages in there seem incorrect.

 # VTK 4.2.2: 3D Visualization Toolkit

Should be 4.4.2.  

 # MayaVi 1.3: 3D Data Visualization Tool

Should be either 1.4 or 1.5, not sure which one is in the latest
build.  You can check in
/Python23/Lib/site-packages/mayavi/__version__.py

 # SciPy 0.3: Scientific Library for Python

Shouldn't this be 0.3.2?

I think you should also mention that it comes with MingW, GCC and SWIG
(which makes quite a difference).

BTW, why was IPython removed from the build?

[Envisage-dev] SVN working copy is huge.

Hi,

I noticed today that my working copy of enthought is *huge* at > 250
MB.  Here is a list of the packages what are > 5MB:

53M     chaco
23M     enable
19M     envisage
22M     freetype
11M     graph
53M     kiva
8.0M    mathtext
13M     pyface
27M     traits

Can something be done to reduce the size?  SVN unfortunately doubles
the storage requirements.  So new users might be surprised by the
large size.

I am not sure I have anything more to add than the pages on the wiki
for TVTK and mayavi2.  Mayavi2 is still under development but TVTK
could probably be mentioned at code.enthought.com.  I am not sure how
you build the installers/tarballs and what you expect.  MayaVi2 is
still not ready for installers.  I can build source packages for TVTK.
However, you might be able to do so just as easily.  The trouble with
TVTK is that it depends on TVTK, traits and PyFace.  So under windows,
perhaps distributing VTK along with it makes sense.  If the user has
their own VTK install then TVTK should be installed from source.  So,
I am not sure what I should do, please let me know what you think.

One more comment on http://code.enthought.com/etlib/

The dependency chart there is very nice but slightly inaccurate.

 1. All packages seem to need scipy_distutils, so they all need scipy
    if only to install them.

 2. TVTK should really require wx since any use of a GUI, ivtk or the
    scene widget or the pipeline browser would require wx.

[Envisage-dev] Final version of announce

Hi,

Made many modifications to reflect the code.enthought.com site,
included Dave's changes and Roberts suggestion.  Unless someone has
problems with this, I'll send this announcement sometime tonight (my
time) or if I'm badly held up, tommorow morning.

cheers,
prabhu

Greetings,

This is to announce the *existence* of the Enthought Tool Suite (ETS).
ETS is a collection of several useful components that together provide
a powerful application framework with special emphasis on scientific
and engineering applications.  There are a large number of components,
some stable and some under heavy development.  These include:

 * Traits: (general purpose: stable)
   - Traits allow one to define special Python object attributes that 
     elegantly support initialization, validation, delegation, 
     notification and visualization (i.e. automatic generation of user 
     interfaces)

 * Endo: (general purpose: stable)
   - Endo is a Traits aware API documentation tool.

 * PyFace: (user interface: stable)

RE: [Envisage-dev] Proposed ETS announce text

Prabhu:

Well, you were the one that was saying ETS was for science. After I went
over all the packages I was familiar with, and saw that none of them had any
kind of a science bent, by process of elimination, I decided that it must be
the TVTK package that was making everything so scientific in nature 

Sounds like ETS is just a general all-around good package for doing all
kinds of stuff
