Wind 5596190377 do command: Make closure support default parameters and type checking (#12056) ... # Description Fixes: #11287 Fixes: #11318 It's implemented by porting the similar logic in `eval_call`, I've tried to reduce duplicate code, but it seems that it's hard without using macros. 3ee2fc60f9/crates/nu-engine/src/eval.rs (L60-L130) It only works for `do` command. # User-Facing Changes ## Closure supports optional parameter ```nushell let code = {|x?| print ($x | default "i'm the default")} do $code ``` Previously it raises an error, after this change, it prints `i'm the default`. ## Closure supports type checking ```nushell let code = {|x: int| echo $x} do $code "aa" ``` After this change, it will raise an error with a message: `can't convert string to int` # Tests + Formatting Done # After Submitting NaN		2024-03-11 18:11:08 +08:00
