Subject: 24.0.50; python mode coloring broke
Date: Sat, 14 Aug 2010 01:05:48 +0200

[Message part 1 (text/plain, inline)]

emacs trunk revno: 101071


How to reproduce:
1/ emacs -Q test.py
2/ coloring is wrong starting L96


The test.py file is joint to this email.


I tried to remove as many lines as possible:

If you remove any line above L25 from the test.py file, the bug
disappears...

If you add or remove lines below L25, the line where the bug starts will
still be L96.

Thanks for the report; sorry no-one ever replied.

It looks like a complicated example file, and I don't know what I am
supposed to be seeing. Line 96 looks the same to me as line 95. Do you
still see this issue, and if so could you say exactly what is wrong?

The test.py file is indeed an unnecessary complicated example.

Here is a simpler file reproducing the issue:

def test():
	""""""
	return None
	
The issue is the following:
All the lines after the empty triple-quoted string are colored with
the 'font-lock-string-face' face.

This seems to be a legit python code:
http://docs.python.org/reference/lexical_analysis.html#string-literals
	
There is the same issue with triple-quoted strings using simple quotes '.

Thanks, that's much clearer. This issue still occurs with the latest
python.el in the Emacs trunk.

I tried this and the current trunk's python.el seems to be working well 
on the given test file.
