After running a few initial commands in a new IPython console (regardless of what they may be), line execution automatically defaults to multline mode and slows down considerably. For example:

Opening new IPython console:
Python 3.5.1 (default, Dec 20 2015, 15:56:10) 
Type "copyright", "credits" or "license" for more information.

IPython 4.0.1 -- An enhanced Interactive Python.

%quickref -> Quick reference.

  ...:

This last line will take several seconds to execute, and all subsequently entered statements will behave similarly, making the console virtually unusable.

Description

What steps will reproduce the problem? When I try to edit any python file there is a noticeable delay for every keystroke. It's almost unusable. The same issue happens with the Anaconda Spyder and the executable downloaded from GitHub. 1. 2. 3.

What is the expected output? What do you see instead?

Description

When restarting ipython kernel or opening a new ipython console session within Spyder, it crashes. Below is the error message. However, the very first ipython console session that get's opened by Spyder, does work. I have reinstalled anaconda with a fresh new download but the problem keeps appearing.

An error ocurred while starting the kernel
Error in sitecustomize; set PYTHONVERBOSE for traceback:

What steps will reproduce the problem?

2. Open a new ipython console tab, or restart current kernel

I guess this can be achieved bu having custom themes on a OS level, but it would be nice to be able to set Spyder to a dark theme directly in Spyder.

Something like what Dark style sheet provides...

Problem Description

A clean conda install from https://www.anaconda.com/download/#windows (version 5.2.0) works for Spyder, but if I then do a 'conda update --all', the resulting configuration is broken. When you run Spyder, launching from Anaconda navigator, you get a message about a missing ordinal 242 in Anaconda3\Library\bin\mkl_intel_thread.dll

This turns out to be because the dlls from mkl-2018.0.3-1 are installed in Anaconda3\Library\bin, but something in Spyder needs the dlls from mkl-2018.0.2-1 instead. If you copy the dlls from Anaconda3\pkgs\mkl-2018.0.2-1\Library\bin into Anaconda3\Library\bin, Spyder then launches normally. (This probably breaks something else, but if so, it's something I haven't yet tried to use ;-)

What steps reproduce the problem?

1. Install Anaconda for Windows
2. run conda update --all
3. Launch Spyder

What is the expected output? What do you see instead?

@goanpeca @ccordoba12 opening this so that you can see what it looks like.

This is not intended to be merged as is. I want to add an intermediate layer with qtawesome that automates certain things like graying disabled font icons etc...

This requires the qtawesome 0.1.6, which I just pushed to pypi. Please update with pip install --upgrade.

Besides, I want to make the spyder font its own project so that people can use it for the web as well, with the same mechanism as fontawesome.

In the Jedi bookmark of https://code.google.com/r/stevensilvester-rich-text-to-thread/source/browse , I have replaced rope with Jedi.

What Jedi offers is an excellent recursiveness that makes it possible to tease out the proper object from very complex code.

Jedi appears to be about as fast as rope, unless you are parsing against a large library for the first time that session. I have engaged with the author of Jedi on how to overcome this. Also, some objects with dynamic docstrings will not show the same docstring as the rope version, such as functools.partial.

Prior to making the speed improvements, perhaps we can default to rope, and lean on Jedi when rope fails to find the object?

I am using a clone of the main development repo on Ubuntu 12.04, 32bit.

Code folding is a really important feature for me when I write long scripts. Please implement this again in Spyder 2.

Description of Changes

• Update shortcut icon for Linux
• Add post-install script for Linux: update shortcut name to allow pinning to Dash
• Updates to napari/label/bundle_tools_2 also gave executable permissions to the installer shell script

Double-clicking the installer script should run the script in a new Terminal window in interactive mode. To see additional installation options, execute in a Terminal:

$ EXPERIMENTAL-Spyder-5.4.2.dev0-Linux-x86_64.sh -h

2. Try to start it.
3. Not starting and throwing the error shown below.

What is the expected output? What do you see instead?

The Spyder IDE.
