[Visualpython-users] Release: VPython 2.9.1

[Jonathan B. <jbr...@ea...>]

This release corrects bugs found in the 2.9.0 release:

display.kb.getkey() was inadvertently renamed display.kb.getkeys()
(corrected).  Thanks to James Roper for finding this bug.

Implicit and explicit conversion from two-tuples to vectors left the z
component of the resulting vector undefined.  On some builds this would
be unnoticeable (setting z to some very small number close to zero) and
on others it would set z to be some very large number.

The instructions for building from source have been corrected in a few
places.  See INSTALL.txt in the source tarball for details.

The Windows download does not include the leading drive letter in the
filenames, which cause problems for some people.  Actually, I "fixed"
this some time ago, but the resulting upload was found later to be
corrupt.

The new downloads may be found at http://www4.ncsu.edu/~jdbrandm/.

[Visualpython-users] Extra VPython window with gdisplay in 2.9.1

[Andrew D. <dou...@la...>]

When I run the graphtest.py demo (or actually any program using gdisplay),
I get the regular 'Graph' window with the demo, but I also
seem to always get a second, unused window labeled 'VPython'.

Does anyone else see this?

Is this with the experimental Boost-based VPython that Jonathan 
Brandmeyer recently released? This is a known bug, and he's working on it.

Yup, the 2.9.1 experimental release.  I just wanted to make sure it wasn't
a local problem on my end.

So far, all my other programs have worked just fine with the new
Boost-based version, so it's looking pretty nice!

I've checked in a patch for this bug to CVS, it will be released soon.

Nice.  Thanks.  I ran into a few glitches while trying to build this on a
Debian Linux/SPARC64 system.  I've enclosed suggested patches (apply with
patch -p1 -N).

The changes are:

INSTALL.txt:
    1.  Debian's "Testing", unfortunately, has python2.3, but only
    Boost 1.30.2.  I put in some notes to that effect.  If it's too much
    or too verbose, go ahead and adjust it to taste.

    2.  Using PYTHONPATH and --prefix to install somewhere safe and out of
    the way only works if PYTHONPATH already exists.  I didn't think
    configure should do that (because you might need to be root to
    make the directory) so I just put in an explicit instruction.

    3.  I fixed a few trivial typos.

configure.ac:
    1.  If compilation of a program with #include <Python.h> fails, the
most likely reason is that Python.h doesn't exist, but there could also be
other local configuration errors.  (In my case, there was a
bit of 32-bit/64-bit confusion in python's pyport.h header.)  I've
suggested a somewhat more general message.

cvisual/Makefile.in:
    1.  The 'make install' step will fail if $prefix/bin doesn't exist
    already.  I added in a conditional mkdir -p command.  (I
    vaguely recall that mkdir -p is not completely portable, but probably
    should be ok everywhere that VPython is likely to be installed.)
