Are these all errors you found?

The unicode literal was added in 3.3: https://www.python.org/dev/peps/pep-0414/

The first one should be if not to_text_string(text):, so this is an easy fix !

[ccordoba12]

I'll fix the error in pygments_patch for 2.3.4. The others were introduced by @goanpeca.

But I think we should just drop support for 3.2 for 2.4 because very few people are running Spyder there (that I know of).

@spyder-ide/core-developers, what do you think?

[blink1073]

I say dump it! Matplotlib dropped 3.2 support recently. I've been trying to get scikit-image to drop it...

[goanpeca]

I am 👍 on dumping it!

[goanpeca]

But I will fix it nevertheless. The package manager has some issues right now besides that, and will get fixed soon. I am normally only testin py2.7 and py3.4 on linux and 3.3 on win (what i can get install with anaconda)

[stonebig]

anaconda can't get install python3.4 on win ?

[goanpeca]

I rephrase... I normally use: Lin (2.7, 3.4) and on win (2.7, 3.3, 3.4)

[ccordoba12]

@goanpeca, don't worry about it. I'm going to follow @blink1073 advice and drop support for Python 3.2 (and 2.6 too) in our next major release. Since your contributions are planned for that release, you don't need to fix those u' cases.

It doesn't make sense to try to support versions which we are not able to test easily, but thanks @Arfrever for letting us know about the problem in pygments_patch

👍 for dropping 2.6 and 3.2. It is coherent with the compatibility with Qt5, new-types signals... Spyder is getting some fresh air !
