Bug ID: 459825
Summary: syntax-highlighting 5.98.0 breaks kate/ktexteditor
from 2018
Classification: Frameworks and Libraries
Product: frameworks-syntax-highlighting
Version: 5.98.0
Platform: Debian unstable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: framework
Assignee: kwrite-bugs-n...@kde.org
Reporter: nfx...@gmail.com
Target Milestone: ---
SUMMARY
I'm using kate/ktexteditor from 2018 (ktexteditor f06e83281268701 / kate
2641fc835e5fecb5, version 18.03.70). When upgrading from syntax-highlighting
framework release 5.97.0 to 5.98.0, highlighting of C source files broke in a
stranger way: after the first number token (like 123), the rest of the line is
rendered in red, and braces matching stops working for that line. This happens
with source code text that parses as number in C. (Numeric digits embedded in
string literals don't cause it.) It seems to affect any and all tokens that
follow the number.
I've built 5.97.0 locally for kate (so only the ancient kate accesses it), and
it works again.
There is no such problem with kate 22.04.3.
While using ancient kate may seem absurd to you, syntax-highlighting probably
accidentally broke compatibility in a subtle way, that might affect other users
of this framework.
STEPS TO REPRODUCE
1. Build old kate/ktexteditor (git hashes see above) with syntax-highlighting
5.98.0. I can't find the instructions how to do this properly, though.
2. Open any .c source file, using the standard C syntax highlighter. (I have no
local syntax .xml files from what I can tell, in fact I wonder where these
files are located at all.)
OBSERVED RESULT
Renders like with 5.97.0, nothing strange visible.
EXPECTED RESULT
Text following a number token is rendered red, until the line ends.
