How to get PyCharm to check PEP8 code style?
Question:
I’m using PyCharm (v 2.7.2) to develop a Django app, but I can’t get it to check PEP8 style violations.
I have enabled “PEP8 coding style violation” in the “Inspctions” section of the settings, but PyCharm doesn’t highlight the style violations.
Is there a way to fix this?
Answers:
For me I found that the best way for me was to include pep8 checking as an external script, something along the lines of this:
The advantage of doing this is that the errors appear as sort of a todo list the bottom of the frame. This way I don’t have to look around the code for errors.
Which version of Python are you using? If it is Python 3 (maybe specifically Windows 64 bit), there are a couple of bugs logged against that on JetBrains’ site:
Mine wasn’t showing up due to the color scheme. By default it’s marked as “weak warning”, so you might have to edit the appearance to make it visible. Editor > Colors & Fonts > General > Errors and Warnings.
OP asks for a way to highlight PEP8 errors on PyCharm, but there’s another way (much clearer in my opinion) to see the violations (extracted from PyCharm’s docs). Open Code | Inspect Code and friends:
Inspection Tool Window
View | Tool Windows | Inspection:
- You can access the tool window this way only when it is already opened through Code | Inspect Code.
- After you deactivate the tool window manually by clicking the Close button, the tool window is again available only through Code | Inspect Code.
The Inspection tool window displays inspection results on separate tabs
Just tested it on a PyCharm Community Edition and it worked like a charm (no pun intended).
Well, I wish I had a better answer, but what helped me was simply the following:
- switch the interpreter from a remote one to a system one
- wait until the Pycharm indexing is done
- switch the interpreter back to the initial/desired one
