# Description Add an extension trait `IgnoreCaseExt` to nu_utils which adds some case insensitivity helpers, and use them throughout nu to improve the handling of case insensitivity. Proper case folding is done via unicase, which is already a dependency via mime_guess from nu-command. In actuality a lot of code still does `to_lowercase`, because unicase only provides immediate comparison and doesn't expose a `to_folded_case` yet. And since we do a lot of `contains`/`starts_with`/`ends_with`, it's not sufficient to just have `eq_ignore_case`. But if we get access in the future, this makes us ready to use it with a change in one place. Plus, it's clearer what the purpose is at the call site to call `to_folded_case` instead of `to_lowercase` if it's exclusively for the purpose of case insensitive comparison, even if it just does `to_lowercase` still. # User-Facing Changes - Some commands that were supposed to be case insensitive remained only insensitive to ASCII case (a-z), and now are case insensitive w.r.t. non-ASCII characters as well. # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` --------- Co-authored-by: Stefan Holderbach <sholderbach@users.noreply.github.com>
