Hold on, does any mutation via cell paths actually work? |

Ignore the specifics of the example in the top post; the config structure changed recently so it's not necessarily still valid. |

I do not think the recent config refactoring is the root cause of this issue, taking |

…7318) # Description Closes #7110. ~~Note that unlike "real" `mut` vars, $env can be deeply mutated via stuff like `$env.PYTHON_IO_ENCODING = utf8` or `$env.config.history.max_size = 2000`. So, it's a slightly awkward special case, arguably justifiable because of what $env represents (the environment variables of your system, which is essentially "outside" normal Nushell regulations).~~ EDIT: Now allows all `mut` vars to be deeply mutated using `=`, on request. # User-Facing Changes See above. # 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.

# Description Closes #7059. Rather than generate a new Record each time $env.config is accessed (as described in that issue), instead `$env.config = ` now A) parses the input record, then B) un-parses it into a clean Record with only the valid values, and stores that as an env-var. The reasoning for this is that I believe `config_to_nu_record()` (the method that performs step B) will be useful in later PRs. (See below) As a result, this also "fixes" the following "bug": ``` 〉$env.config = 'butts' $env.config is not a record 〉$env.config butts ``` ~~Instead, `$env.config = 'butts'` now turns `$env.config` into the default (not the default config.nu, but `Config::default()`, which notably has empty keybindings, color_config, menus and hooks vecs).~~ This doesn't attempt to fix #7110. cc @Kangaxx-0 # Example of new behaviour OLD: ``` 〉$env.config = ($env.config | merge { foo: 1 }) $env.config.foo is an unknown config setting 〉$env.config.foo 1 ``` NEW: ``` 〉$env.config = ($env.config | merge { foo: 1 }) Error: × Config record contains invalid values or unknown settings Error: × Error while applying config changes ╭─[entry #1:1:1] 1 │ $env.config = ($env.config | merge { foo: 1 }) · ┬ · ╰── $env.config.foo is an unknown config setting ╰──── help: This value has been removed from your $env.config record. 〉$env.config.foo Error: nu:🐚:column_not_found (link) × Cannot find column ╭─[entry #1:1:1] 1 │ $env.config = ($env.config | merge { foo: 1 }) · ──┬── · ╰── value originates here ╰──── ╭─[entry #2:1:1] 1 │ $env.config.foo · ─┬─ · ╰── cannot find column 'foo' ╰──── ``` # Example of new errors OLD: ``` $env.config.cd.baz is an unknown config setting $env.config.foo is an unknown config setting $env.config.bar is an unknown config setting $env.config.table.qux is an unknown config setting $env.config.history.qux is an unknown config setting ``` NEW: ``` Error: × Config record contains invalid values or unknown settings Error: × Error while applying config changes ╭─[C:\Users\Leon\AppData\Roaming\nushell\config.nu:267:1] 267 │ abbreviations: true # allows `cd s/o/f` to expand to `cd some/other/folder` 268 │ baz: 3, · ┬ · ╰── $env.config.cd.baz is an unknown config setting 269 │ } ╰──── help: This value has been removed from your $env.config record.
