Bug ID: 496460
Summary: Lookarounds break the "export pattern" feature.
Classification: Applications
Product: kate
Version: 24.08.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: search
Assignee: kwrite-bugs-n...@kde.org
Reporter: qaliboire.bug_rep...@pm.me
Target Milestone: ---
SUMMARY
When a regular expression search is done using a pattern that includes a
lookaround, the "export pattern" feature outputs the capture pattern entered by
user, instead of the contents of the corresponding capturing group(s).
STEPS TO REPRODUCE
1. open a new editor and type:
1foo
2bar
2. in the "Search" section, do a regular expression search for "(\d)(?=\w+)";
3. right-click in the sub-section that displays the matches and select "Export
matches";
4. type "\1" in the "Export Pattern" field and click on "Generate".
OBSERVED RESULT
The "Result" field shows:
\1
\1
EXPECTED RESULT
We expect the same output as we would get with the pattern "(\d)\w+", i.e.:
1
2
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
Lookbehinds (e.g. "(?<=\d)(\w+)") cause the same problem as lookaheads.
