Hi Fabio,

That's great. I tried the new upgrade of PyDev 2.3 for about 1 hour (add "OpenGL"
back to Forced Builtins), everything is OK.
Problem is solved!

Thanks a lot for your excellent work!!
best regards & have a good weekend!

Thanks Fabio!

 looked at my environment variables, and the only one python related was PYTHONHOME,
and that was set to C:\csvn\Python25.  So I changed that to C:\Python32\ and
I added an environment variable for PYTHONROOT and set that to the same value.
It now seems to work!
I must have had a some python directories laying around from an odd svn installation
or something...

Thanks again!

[Pydev-users] [Users] Jython 2.2.1 has a bug in list.sort()

[SourceForge.net <no...@so...>]

The following forum message was posted by r_walter at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4885574:

Hello,

PyDev 2.3 introduced internally Jython 2.2.1. This version has a bug in the
sorting routine. A fix existed but was never released in a Jython 2.2.2. The
fix was obsolete with Jython 2.5.

See this: http://bugs.jython.org/issue1835099#

I guess no one included the bugfix given there for PyDev.

If I change it to:

    ~/workspace/normal_dir/linked_subdirs

it works just fine.  I suspect that the code is looking for a file or a
directory and failing to resolve the symbolic link as it should.

The following forum message was posted by fabioz at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4884584:

Which PyDev version are you using?

The problem seems to be that it's mixing Python 3.2.2 (which you said you're
configuring) and Python 2.5 (where the error appears).

I think this can happen if you have PYTHONROOT configured to Python 2.5 and
are trying to execute Python 3.2 (because the docs say that the PYTHONROOT env
will be added to the PYTHONPATH anyways, so, try closing eclipse, cleaning up
your PYTHONROOT variable, restart Eclipse and see if it gets it right again).

If it still doesn't work, please report back posting more details on your environment
variables.

Cheers,

Fabio

[Pydev-users] [Users] Python Interpreter Error with PyDev

Hi,
This is my first email to this list, so I apologize if there's a better mailing-list
for this type of question.

I'm looking to get started with python development, so I downloaded Python 3.2.2
and PyDev IDE for Eclipse.  When I go to configure my interpreter for a new
python project, Windows gives me the following error:

"python.exe has stopped working"

and then Eclipse shows

"Error getting info on interpreter
"See error log for details.
No output was in the standard output when trying to create the interpreter
info.
The error output contains:>>Fatal Python error: Py_Initialize: unable to load
the file system codec
  File "C:\csvn\Python25\\lib\encodings\__init__.py", line 120
    raise CodecRegistryError,\
                            ^
SyntaxError: invalid syntax

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
<<"

Does anybody have any idea what this means or what I'm doing wrong?  I've tried
re-installing Python, but still can't get it to work.
And again, if I'm in the wrong place, please direct me to the proper forum.

[Pydev-users] PyDev 2.3.0 Released

[Fabio Z. <fa...@gm...>]

Hi All,

PyDev 2.3.0 has been released

Details on PyDev: http://pydev.org
Details on its development: http://pydev.blogspot.com

Release Highlights:
-------------------------------

* Pep8.py integrated (must be enabled in PyDev > Editor > Code
Analysis > pep8.py).
* Faster PyDev startup (internal Jython upgraded to version 2.2.1 --
and also optimized for PyDev).
* Action to select/deselect scope (Shift+Alt+Up/Down).
* Fix: cache issue where the PYTHONPATH in memory became different
from the PYTHONPATH configured for a project.
* Fix: OutOfMemoryError when dealing with PyOpenGL.
* Fix: deadlock (could occur in a race condition when importing a
project with an existing Python configuration).
* Fix: code-completion integration issue with IPython 011 (patch from
jonahkichwacoders).
* Fix: annotation could remain in editor after removing a marker.
* Fix: BadLocationException on extract local refactoring.


What is PyDev?
---------------------------

PyDev is a plugin that enables users to use Eclipse for Python, Jython
and IronPython development -- making Eclipse a first class Python IDE
-- It comes with many goodies such as code completion, syntax
highlighting, syntax analysis, refactor, debug and many others.

[Pydev-users] Not following symbolic links for F3 resolution

[Kenneth L. <ke...@lo...>]

Hi,

When I hit F3 to bring up a function edit, PyDev claims it cannot find the
source if the function has a symbolic link in the path.  Everything else
works perfectly as it should, yet F3 claims the resource does not exist.

I can get it to work by using a File >> New >> Folder and making a
pseudo-link through that, but that has its own problems since it does not
create a symbolic link in the file system.  So, to get manual tests to
work, I have to create the symbolic link as well.  The problem with doing
so is that when I try to debug, PyDev complains that I have two copies of
the function in the workspace and for every F5, F6, or F8 I hit, I have to
chose the non-linked one, a real PITA.

Looks like I just reported two bugs here.  Should I file them, or is there
a workaround I should try first?

...Thanks,
...Ken

If no .py file is displayed in the Eclipse Editor, then everything is OK.

I am using PyDev in Eclipse and migrating some source code for a Django project.
However, Eclipse or the PyDev plugin (I don't know which) is displaying an 'X'

I wish that I knew what the error is about, so that I could make sure that my
