Nix Shell and Locales

From here. Often nix-shell invocations have the following issue:

1bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

The fix is in two parts:

1# Install glibc
2nix-env -i glibc-locales

Then use it in the shellHook as:

1shellHook = ''
2  # Locale
3  export LOCALE_ARCHIVE=${pkgs.glibcLocales}/lib/locale/locale-archive
4'';

Or directly as export LOCALE_ARCHIVE="$(nix-env --installed --no-name --out-path --query glibc-locales)/lib/locale/locale-archive"
