# Description * I was dismayed to discover recently that UnsupportedInput and TypeMismatch are used *extremely* inconsistently across the codebase. UnsupportedInput is sometimes used for input type-checks (as per the name!!), but *also* used for argument type-checks. TypeMismatch is also used for both. I thus devised the following standard: input type-checking *only* uses UnsupportedInput, and argument type-checking *only* uses TypeMismatch. Moreover, to differentiate them, UnsupportedInput now has *two* error arrows (spans), one pointing at the command and the other at the input origin, while TypeMismatch only has the one (because the command should always be nearby) * In order to apply that standard, a very large number of UnsupportedInput uses were changed so that the input's span could be retrieved and delivered to it. * Additionally, I noticed many places where **errors are not propagated correctly**: there are lots of `match` sites which take a Value::Error, then throw it away and replace it with a new Value::Error with less/misleading information (such as reporting the error as an "incorrect type"). I believe that the earliest errors are the most important, and should always be propagated where possible. * Also, to standardise one broad subset of UnsupportedInput error messages, who all used slightly different wordings of "expected `<type>`, got `<type>`", I created OnlySupportsThisInputType as a variant of it. * Finally, a bunch of error sites that had "repeated spans" - i.e. where an error expected two spans, but `call.head` was given for both - were fixed to use different spans. # Example BEFORE ``` 〉20b | str starts-with 'a' Error: nu:🐚:unsupported_input (link) × Unsupported input ╭─[entry #31:1:1] 1 │ 20b | str starts-with 'a' · ┬ · ╰── Input's type is filesize.

Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date.
