Bug ID: 407327
Summary: Perl5 syntax highlight gets confused at //
Product: kate
Version: 18.08.0
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: syntax
Assignee: kwrite-bugs-n...@kde.org
Reporter: hei...@lsd.dk
Target Milestone: ---
SUMMARY
With some files, the perl syntax highlighting gets confused.
STEPS TO REPRODUCE
1. Create a new file
2. Paste in the two lines:
$x = ns // "";
print $x;
3. Save the file as foo.pl
OBSERVED RESULT
The syntax highlight goes wrong at the second slash. Everything after that is
mostly green
EXPECTED RESULT
The highlighting should be right. "print" should be black.
SOFTWARE/OS VERSIONS
Debian/Buster
KDE Plasma Version: 4:5.14.5.1-1 (debian plasma-workspace)
KDE Frameworks Version: KDE Frameworks 5.54.0
Qt Version: Qt 5.11.3 (built against 5.11.3)
The xcb windowing system
Kate Part Version 5.54.0
ADDITIONAL INFORMATION
It looks like the problem has something to do with the "//" operator. In some
contexts that works all right, like if I use $ns instead of ns.
The original code example is from Catmandu::Exporter::RDF, from
libcatmandu-rdf-perl 0.32-2, where the line looks like this:
RDF::aREF::Decoder->new(
ns => $_[0]->ns // ($_[0]->ns eq 0 ? { } : RDF::NS->new),
callback => $_[0]->model
);
