Bug ID: 450484
Summary: Kate R syntax colorer puts extra underline on common
operator
Product: kate
Version: 21.08.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: david.cortes.riv...@gmail.com
Target Milestone: ---
SUMMARY
If I open a .R file with Kate, it will show the operator ":=" with an extra
underline in the right sign, making it show **three** bars instead of two. This
is very annoying since it makes it harder to read the code and makes people
think they've inputted the wrong symbol. These two symbols together (:=) are
very common in R code, and what's more, kate's coloring backed is offered as
one of the styles for "rmarkdown" (what most people use to write tutorials,
manuals, vignettes, etc. with R code), but this issue makes it a very
unsuitable candidate (and it's understandably not the default BTW, even though
it otherwise looks better than the default style from rmarkdown). I have on
multiple ocassions decided to use a Python syntax highlighter for R code
instead due to this issue alone.
STEPS TO REPRODUCE
1. Save this text as a .R file and open it with Kate:
library(data.table)
dt <- data.table(col1 = 1:3)
dt[, col1 := col1+1]
OBSERVED RESULT
The ":=" operator has three lines.
EXPECTED RESULT
The ":=" operator should have two lines.
