Description Piotr Mierzwinski 2021-03-04 23:40:44 UTC

SUMMARY
Sematic highlighting stops work after  insert one or more lines, but only in code present below inserted lines. Needs to refresh file to get proper sematic highlighting in opened file.
I think this didn't happen in previous version, so seems to be regression.

STEPS TO REPRODUCE
1.  Open project with several files
2.  Open couple files
3. After indexing finished try to modify one of them
4. In the middle of code insert one or more lines (with correct syntax)

OBSERVED RESULT
Sematic highlighting stops work in code below inserted lines and needs to refresh whole file

EXPECTED RESULT
Sematic highlighting should not stops work after inserting any lines

This is a bug in KTextEditor 5.79, not in KDevelop directly. It will be fixed by the next KDE Frameworks release.
