Text Case is now built on Apple's Swift Argument Parser, meaning the way you interact with the textcase command is slightly different.
For starters, textcase now has two sub commands: format and list-formats. Although the default sub command is format, so that's not explicitly required.
So to view a list of formats, you now need to use textcase list-formats.
As for the formatting, here are the various options:
USAGE: text-case format --format <format> [--input <input>] [--input-file <file>] [--output-file <file>]
OPTIONS:
-f, --format <format> Format to be used.
-i, --input <input> Text to be formatted.
--input-file <file> Path of file to be used as input.
--output-file <file> Path of file to be used as output.
--version Show the version.
-h, --help Show help information.
And, of course, you can use textcase --help, textcase format --help, or textcase list-formats --help for more information.
