Sentry Crash Report:

Description Laura David Hurka 2018-11-28 17:00:02 UTC 
SUMMARY
C defines written in uppercase snake style are not recognized/accesible by kate's autocompletion (Ctrl+Space), like words in lowercase snake style are.

STEPS TO REPRODUCE
1. Write '#ifndef SNAKE_STYLE_H'
2. Write '#define SSH' or '#define ssh'
3. Trigger autocompletion (Ctrl+Space, if you disabled auto-autocompletion)

OBSERVED RESULT
Autocompletion does nothing. Uppercase words have to be written exactly, before they are recognized (SNA[...] instead of SSH)

EXPECTED RESULT
Autocompletion recognizes the first letters 'S', 'S', 'H', which follow \b or _, so SSH (or even ssh) can be completed. Because the word is all uppercase, 'NAKE' and 'TYLE' are no "first letters", like capital letters in camel-case are.

SOFTWARE/OS VERSIONS
Everything I used in the last 6 Years (Kubuntu, other *buntu, Raspian, Windows, kdelibs4, KF5, many kate versions...)
Comment 1 Waqar Ahmed 2021-10-11 07:24:22 UTC 
most likely an issue in the fuzzy matcher in KTextEditor's completion. Fix would be trivial I think.

Do proper fuzzy matching in completion

Use KFuzzyMatcher for fuzzy matching. Results are better and fixes the
linked bug.

Also remove some dead code related to case sensitivity while at it.
