What version of ripgrep are you using?

ripgrep 15.1.0

How did you install ripgrep?

Homebrew

What operating system are you using ripgrep on?

macOS 15.7.4

Describe your bug.

--type should be case-insensitive or at least have an option to

rg -g '*.htm' will search in 1.HTM when --glob-case-insensitive is provided
rg -t html won't

and it's highly illogical. file extensions originally came from case-insensitive filesystems, so in a random codebase you can see both *.HTM and *.html, they're the same. but somehow the uppercase versions are not searched when using --type and that's terribly wrong.

basically that's the intention of the --type: search in all of them: *.html, *.htm and *.HTM, because the user isn't sure, which one to search. in this logic searching *.htm, but not *.HTM just doesn't make sense!

What are the steps to reproduce the behavior?

I'm using macOS with a default, i.e. case-insensitive filesystem. I do:

$ echo AAA > 1.HTM
$ echo AAA > 2.htm
$ alias rg
rg='rg --smart-case --glob-case-insensitive --no-heading'
$ rg -g '*.htm' AAA
# this matches both files:
2.htm:1:AAA
1.HTM:1:AAA
$ rg -t html AAA
# and this only the lowercase one:
2.htm:1:AAA

What is the actual behavior?

$ rg -t html --debug AAA

What is the expected behavior?

$ echo AAA > 2.htm
$ rg -t html AAA
2.htm:1:AAA
1.HTM:1:AAA

@chillum I implemented this as an opt-in --type-case-insensitive flag (rather than changing the default) to avoid breaking changes on Linux where .html and .HTML are genuinely different files. If the maintainer prefers making it the default, I'm happy to change the approach.
