Created attachment 161018 [details] Example script for bug reroduction SUMMARY The exclamation mark (!) is a special parameter that will "expands to the process ID of the job most recently placed into the background, whether executed as an asynchronous command or using the bg builtin" according to the Bash manual, however currently when encountering the `"${!}"` (opening double-quote, dollar sign, opening curly braces, exclamation mark, closing curly braces, closing double-quote) character sequence all text are highlight as red until the next occurrence of `"${!}"`. Expansion without the curly braces pair,(`$!`), however, does not reproduce such problem. STEPS TO REPRODUCE 1. Download attached reproducing script 2. Open the script with Kate, etc. 3. Profit. OBSERVED RESULT Text between two `"${!}"`s is highlighted red. EXPECTED RESULT Text between two `"${!}"`s shouldn't be highlighted red. SOFTWARE/OS VERSIONS Linux: Ubuntu 22.04LTS KDE Frameworks Version: 5.92.0 (also reproduced in 5.105.0 snap) Qt Version: 5.15.3 (also reproduced in 5.105.9 snap) ADDITIONAL INFORMATION Also reproduced with the definition file of commit ca42b1ed.
