Bahex 442df9e39c Custom command attributes (#14906) ... # Description Add custom command attributes. - Attributes are placed before a command definition and start with a `@` character. - Attribute invocations consist of const command call. The command's name must start with "attr ", but this prefix is not used in the invocation. - A command named `attr example` is invoked as an attribute as `@example` - Several built-in attribute commands are provided as part of this PR - `attr example`: Attaches an example to the commands help text ```nushell # Double numbers @example "double an int" { 5 | double } --result 10 @example "double a float" { 0.5 | double } --result 1.0 def double []: [number -> number] { $in * 2 } ``` - `attr search-terms`: Adds search terms to a command - ~`attr env`: Equivalent to using `def --env`~ - ~`attr wrapped`: Equivalent to using `def --wrapped`~ shelved for later discussion - several testing related attributes in `std/testing` - If an attribute has no internal/special purpose, it's stored as command metadata that can be obtained with `scope commands`. - This allows having attributes like `@test` which can be used by test runners. - Used the `@example` attribute for `std` examples. - Updated the std tests and test runner to use `@test` attributes - Added completions for attributes # User-Facing Changes Users can add examples to their own command definitions, and add other arbitrary attributes. # Tests + Formatting - 🟢 toolkit fmt - 🟢 toolkit clippy - 🟢 toolkit test - 🟢 toolkit test stdlib # After Submitting - Add documentation about the attribute syntax and built-in attributes - `help attributes` --------- Co-authored-by: 132ikl <132@ikl.sh>		2025-02-11 06:34:51 -06:00
