# Description While #11057 is merged, it's hard to tell the difference between `--flag: bool` and `--flag`, and it makes user hard to read custom commands' signature, and hard to use them correctly. After discussion, I think we can deprecate `--flag: bool` usage, and encourage using `--flag` instead. # User-Facing Changes The following code will raise warning message, but don't stop from running. ```nushell ❯ def florb [--dry-run: bool, --another-flag] { "aaa" }; florb Error: × Deprecated: --flag: bool ╭─[entry #7:1:1] 1 │ def florb [--dry-run: bool, --another-flag] { "aaa" }; florb · ──┬─ · ╰── `--flag: bool` is deprecated. Please use `--flag` instead, more info: https://www.nushell.sh/book/custom_commands.html ╰──── aaa ``` cc @kubouch # Tests + Formatting Done # After Submitting - [ ] Add more information under https://www.nushell.sh/book/custom_commands.html to indicate `--dry-run: bool` is not allowed, - [ ] remove `: bool` from custom commands between 0.89 and 0.90 --------- Co-authored-by: Antoine Stevan <44101798+amtoine@users.noreply.github.com> |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
