Example showing string parsing instead of file parsing?

[tin2tin]

I'm trying to implement pycodestyle in an add-on for the Blender Text Editor, but having pycodestyle to read re-saved file, while editing is too slow, so my question is if it is possible to parse a string directly instead of opening a saved file? And if yes, then my next question is if there are any examples showing how to do that?

I'm sorry I couldn't find a forum dealing with pycodestyle, to ask this question.
