# Description This corrects the parsing of unknown arguments provided to known externals to behave exactly like external arguments passed to normal external calls. I've done this by adding a `SyntaxShape::ExternalArgument` which triggers the same parsing rules. Because I didn't like how the highlighting looked, I modified the flattener to emit `ExternalArg` flat shapes for arguments that have that syntax shape and are plain strings/globs. This is the same behavior that external calls have. Aside from passing the tests, I've also checked manually that the completer seems to work adequately. I can confirm that specified positional arguments get completion according to their specified type (including custom completions), and then anything remaining gets filepath style completion, as you'd expect from an external command. Thanks to @OJarrisonn for originally finding this issue. # User-Facing Changes - Unknown args are now parsed according to their specified syntax shape, rather than `Any`. This may be a breaking change, though I think it's extremely unlikely in practice. - The unspecified arguments of known externals are now highlighted / flattened identically to normal external arguments, which makes it more clear how they're being interpreted, and should help the completer function properly. - Known externals now have an implicit rest arg if not specified named `args`, with a syntax shape of `ExternalArgument`. # Tests + Formatting Tests added for the new behaviour. Some old tests had to be corrected to match. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] release notes (bugfix, and debatable whether it's a breaking change) |

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.
