Hi all,

On the behalf of Spyder's development team 
(http://code.google.com/p/spyderlib/people/list), I'm pleased to 
announce that Spyder 2.3.2 has been released and is available for 
Windows XP/Vista/7/8, GNU/Linux and MacOS X: 
https://bitbucket.org/spyder-ide/spyderlib/downloads

This release represents more than 2 months of development since 2.3.1 
and introduces major enhancements and new features:

* Editor
   - Improve cells visualization
   - Add support for drag selection and improve look of line number area
   - Open on it any text file present in the Variable Explorer
   - View and edit IPython notebooks as Json files
   - Syntax highlighting for Json and Yaml files

* Variable Explorer:
   - Import csv files as Pandas DataFrames
   - Improve browsing speed for NumPy arrays and DataFrames with more 
than 1e5 elements

* IPython Console
   - Add a stop button to easily stop computations

We fixed almost 40 bugs, merged 13 pull requests from 8 authors and 
added about 150 commits between these two releases. This is a very 
important bugfix release which solved a lot of unicode problems in our 
consoles, the variable explorer and the main interface, so everyone is

Spyder suddenly takes time to open up

Dear all, 
I am using Spyder on Mavericks and everything was ok until a week ago when, suddenly, Spyder takes at least 10 minutes to open after I click its icon. What can be the reason for this problem?

Thank you in advance for your time and consideration

Bug when using sympy.S() ?

Hi,

I am reporting this here because I do not know for sure 1) whether this is a bug; 2) whether this is an error from spyder side or sympy side.

Brief description: the internal console reports TypeError and gets focus whenever I type S( in the editor, after from sympy import S

How to reproduce:

(New file)

from sympy import S

S(


And right here, the editor will lose focus and the internal console get focus. It says:

Spyder Internal Console

This console is used to report application
internal errors and to inspect Spyder
internals with the following commands:
  spy.app, spy.window, dir(spy)

Please don't use it to run your code

Spyder 2.3.1 incompatible with Enthought Canopy 1.5.0.2717 on OSX 10.10

Hi friends,

Like several others on this forum, I am experiencing problems getting Enthought Canopy and Spyder to interact correctly. More specifically, I would like to load modules that are installed into my Canopy distribution when using the IPython and Python consoles inside Spyder. When I do this, I encounter errors. Here is my exact setup.



Operating System: OSX 10.10.1 (latest)
Enthought Canopy Version: 1.5.1.2730 (latest; 64-bit; academic version)
Spyder Version: 2.3.1 (latest; installed via dmg)
IPython version: 2.3.1-1 (latest; installed via Canopy Package Manager)



Here are the only lines relating to Canopy in my ~/.bash_profile file.

#
# Added by Canopy installer on 2013-09-01
# VIRTUAL_ENV_DISABLE_PROMPT can be set to '' to make bashprompt show that Canopy is active, otherwise 1
# VIRTUAL_ENV_DISABLE_PROMPT='1' source /Users/mike/Library/Enthought/Canopy_64bit/User/bin/activate
#
export ETS_TOOLKIT=qt4
export QT_API=pyside
export PATH=/Users/mike/Library/Enthought/Canopy_64bit/User/bin:$PATH

#
# Exporting the paths of Canopy Python libraries so that a custom-built GDB can load them 
#
export DYLD_LIBRARY_PATH=/Applications/Canopy.app/appdata/canopy-1.1.0.1371.macosx-x86_64/Canopy.app/Contents:$DYLD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=/Applications/Canopy.app/appdata/canopy-1.1.0.1371.macosx-x86_64/Canopy.app/Contents/lib:$DYLD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=/Users/mike/Library/Enthought/Canopy_64bit/User:$DYLD_LIBRARY_PATH



Here is what I see when I type "python" from the console. Note that I can import matplotlib.pylot without errors.

I have configured Spyder to point to Canopy python as follows. I have set the "Spyder > Preferences... > Console > Advanced Settings > Python executable" setting to "/Users/mike/Library/Enthought/Canopy_64bit/User/bin/python" without the quotes.

I have configured Spyder to use the default PYTHONSTARTUP script as follows. I have set the  "Spyder > Preferences... > Console > Advanced Settings > PYTHONSTARTUP replacement" setting to the "Default PYTHONSTARTUP script" option.



Here is where I begin to see symptoms of my issue. When I attempt to navigate to the IPython console within Spyder, I get the following error.

"An error ocurred while starting the kernel
Either:
Your IPython frontend and kernel versions are incompatible or
You don't have IPython installed in your external interpreter.
In any case, we're sorry but we can't create a console for you."

When I navigate to the Console within Spyder, I see that Canopy Python has been loaded correctly. However, when I try to import matplotlib.pyplot I get the following error.

I noticed that people on this forum were having similar issues with older versions of Spyder. Are there any workarounds to this specific issue, for this specific version of Spyder? Can I install an experimental version from source to get this working? This is a showstopper issue for me that prevents me from using Spyder in my work. Thank you for your help  :)

Cannot start Syder 3.3.1 on Windows 8.1 PySide.QtGui import error

Hi guys,

I try to start Syder 2.3.1 on my Windows 8.1 64bit, but I always get an error message. But my PySide seems to be OK. I do not understand, why it says: DLL load failed: %1 ist keine zulässige Win32-Anwendung. The --reset options gives the same error.

I cannot remeber, that I did not install any 32bit appliactions ....

Related to Issue 1970: `import pexpect` fails on Windows

Please revisit Issue 1970. It seems like the new dependency on pexpect breaks Windows support. Is there a pexpect module that works on Windows? The docs say no.

I have added a comment to the issue tracker.  I produce ImportError when running `python.exe bootstrap.py`.
