# Description This closes #7498, as well as fixes an issue reported in https://github.com/nushell/nushell/pull/7002#issuecomment-1368340773 BEFORE: ``` 〉[{foo: 'bar'} {}] | get foo Error: nu:🐚:column_not_found (link) × Cannot find column ╭─[entry #5:1:1] 1 │ [{foo: 'bar'} {}] | get foo · ────────┬──────── ─┬─ · │ ╰── value originates here · ╰── cannot find column 'Empty cell' ╰──── 〉[{foo: 'bar'} {}].foo ╭───┬─────╮ │ 0 │ bar │ │ 1 │ │ ╰───┴─────╯ ``` AFTER: ``` 〉[{foo: 'bar'} {}] | get foo Error: nu:🐚:column_not_found (link) × Cannot find column ╭─[entry #1:1:1] 1 │ [{foo: 'bar'} {}] | get foo · ─┬ ─┬─ · │ ╰── cannot find column 'foo' · ╰── value originates here ╰──── 〉[{foo: 'bar'} {}].foo Error: nu:🐚:column_not_found (link) × Cannot find column ╭─[entry #3:1:1] 1 │ [{foo: 'bar'} {}].foo · ─┬ ─┬─ · │ ╰── cannot find column 'foo' · ╰── value originates here ╰──── ``` EDIT: This also changes the semantics of `get`/`select` `-i` somewhat. I've decided to leave it like this because it works more intuitively with `default` and `compact`. BEFORE: ``` 〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon null ``` AFTER: ``` 〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon [[foo]; [null], [null], [null]] ``` # User-Facing Changes See above. EDIT: the issue with holes in cases like ` [{foo: 'bar'} {}].foo.0` versus ` [{foo: 'bar'} {}].0.foo` has been resolved. # Tests + Formatting Don't forget to add tests that cover your changes. 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.
