Indeed, because even if Geany's *filetype_extensions.conf* list `*.htm` under `HTML`, the patterns are case sensitive so won't match `foo.HTM`. We could add various uppercase variants including `HTM` and `HTML`.
PS: and no, just being case insensitive is not really an option, as some extensions are case sensitive, like `.C` which is C++, but `.c` is C. Maybe we could consider as an option to perform a second case-insensitive pass in case we didn't find a match. -- You are receiving this because you are subscribed to this thread.
