[Pierre Raybaut]

Hi all,

I am pleased to announced that Spyder v1.1.7 and Spyder v2.0.0beta4
have been released:

* Spyder v1.1.7 -- a couple of bug fixes since v1.1.6:
* Fixed PyQt compatibility issues related to QTreeWidgetItem
objects construction
* Attempt to fix Issue 318 / PyQt compatibility issues
* Fixed PyQt compatibility issue: setProperty's 2nd argument must
be a QVariant on some PyQt versions

* Spyder v2.0.0beta4 -- a lot of bugfixes since beta2, here are
some
of the recent changes:
* new: real-time code analysis (warnings, errors, todos) with a
customizable timeout (analysis was performed only when saving file)
* new in variable explorer: multiple data files may be imported at
once
* new in source editor: added shortcut to view object in object
inspector
* new in source editor: added option to insert automatically
closing parentheses, brackets and braces
* new in source editor: added option to unindent automatically
after 'else', 'elif', 'finally', etc.
* new in source editor: added option to save all files before
running script
* source editor: a lot of bugfixes regarding breakpoints, file
list management dialog, file selection combo box, ...
* fix PyQt compatibility issues (same as in v1.1.7 -- see above)
* and a lot of bugfixes: code completion, outline explorer
sorting, maximized widgets, etc.

I tried spyder 2.0.0beta4 with WindowsXP32, py2.5.2 Qt 4.4.1 PyQt 4.4.3

The first time I started spyder it crashed. Starting in debug mode
spyder.py -d, I get a long list of:

Traceback (most recent call last):
File "C:\Programs\Python25\lib\site-packages\spyderlib\widgets\codeeditor\code
editor.py", line 827, in viewportEvent
return super(CodeEditor, self).viewportEvent(event)
AttributeError: 'super' object has no attribute 'viewportEvent'

The editor doesn't work, I cannot edit, but both ipython and regular
shells work, doing some simple examples and with execfile(...). I
didn't try other things.

(I'm not completely sure about this one because I had lot's of other
python shells open.)
After shutting down spyder, I still had several stray python processes
open, two of kept doing a very large number of disc reads/writes
according to the windows task managers. This could also be a
consequence of the initial crash.

That is quite weird because the inheritance diagram is the following:
CodeEditor (spyderlib) <-- TextEditBaseWidget (spyderlib) <--
QPlainTextEdit (Qt) <-- QAbstractScrollArea (Qt)
The last one (QAbstractScrollArea) has a method named
'viewportEvent'...

Are you sure that every single previous Spyder version has been
removed on your machine?

If that's not it, could you please try and replace the line:
return super(CodeEditor, self).viewportEvent(event)
by the following line:
TextEditBaseWidget.viewportEvent(self, event)
or, if it still does not work, by the following two lines:
from PyQt4.QtGui import QPlainTextEdit
QPlainTextEdit.viewportEvent(self, event)

Thanks,
Pierre

I only have one spyderlib directory in site-packages, I have previous
spyder-xxx directories but they should be on the python path.

this worked, the debug console doesn't show the error anymore and I
get the text in the texteditor.

now I get a new error:

Traceback (most recent call last):
File "C:\Programs\Python25\lib\site-packages\spyderlib\widgets\codeeditor\code

editor.py", line 792, in resizeEvent
super(CodeEditor, self).resizeEvent(event)
AttributeError: 'super' object has no attribute 'resizeEvent'

---
After "Loading editor..." I also get :

Traceback (most recent call last):

File "C:\Programs\Python25\lib\site-packages\spyderlib\widgets\editor.py", lin
e 213, in run
self.analysis_results = check(source_code, filename=self.filename)
File "C:\Programs\Python25\lib\site-packages\spyderlib\widgets\editortools.py"
, line 55, in check
pyflakes.messages.UndefinedExport,
AttributeError: 'module' object has no attribute 'UndefinedExport'

(I think I had this one also before)

this exception goes away if I also replace the super call by

TextEditBaseWidget.resizeEvent(self, event)

[josef...@gmail.com]

I cleared this one up, I had both pyflakes 0.3.0 and 0.4.0 on the
path, IDLE (import pyflakes) imported 0.4.0, spyder imported 0.3.0,
which didn't have 'UndefinedExport'.
After removing pyflakes 0.3.0 from my python path, I don't have any
error messages left in the debug console.

Now that spyder looks like it's working again, 2 questions:
Is it still possible to change the font in the editor and the shells,
I didn't see an option?
Is it possible to start the ipython shell without namespace pollution,
and how? e.g. no "from numpy import *", mlab, ...?

>>> len(locals().keys()) #after startup
IDLE : 5
Spyder shell: 9
ipython shell : 915 ! how does anyone know what's what under this condition ?

Thanks,

Josef

I think that these issues with 'super' are related to PyQt v4.4 which
was not dealing well with this mecanism.
I'll fix this in next release:

Again in "Preferences" > "Console": click on tab "External modules"
and change the IPython command line options.
The namespace pollution you are referring to is due to the 'pylab'
option - removing it should help.

I think that I changed preferences this way in previous versions, but
in 2.0beta4 the list on the left side of the preferences window is
empty. The only options I see are on the right side for the interface.

Thanks, spyder is starting to look good again in my setup.

If you want to increase the version of PyQt that is required for
spyder, then I could update it.
But then a version check would be useful to inform the user.

Thanks,

Josef

Could you send me a screenshot?
(that is not normal)
