Is there a way to use
highlight-regexp in a case-insensitive way? I'm parenthesizing an expression in my regexp and refer to it using
\1 later and I want to match this regardless of case. I'm trying to find occurrences of repeated words (with maybe some other words in between), even if they are differently capitalized, e. g. in
One two three. Four five six four seven eight nine.
I would like to highlight the phrase
Four five six four due to the repeated word
four. My approach is this regexp:
I will work fine for repeated words with exactly equal capitalization but it does not work if the capitalization doesn't match.
I also tried setting
case-fold-search to various values but it does not seem to be used for
Is there any way to highlight my repeated word case?
