Stefan Holderbach 86cd387439 Refactor and fix Config<->Value mechanism (#10896) ... # Description Our config exists both as a `Config` struct for internal consumption and as a `Value`. The latter is exposed through `$env.config` and can be both set and read. Thus we have a complex bug-prone mechanism, that reads a `Value` and then tries to plug anything where the value is unrepresentable in `Config` with the correct state from `Config`. The parsing involves therefore mutation of the `Value` in a nested `Record` structure. Previously this was wholy done manually, with indices. To enable deletion for example, things had to be iterated over from the back. Also things were indexed in a bunch of places. This was hard to read and an invitation for bugs. With #10876 we can now use `Record::retain_mut` to traverse the records, modify anything that needs fixing, and drop invalid fields. # Parts: - Error messages now consistently use the correct spans pointing to the problematic value and the paths displayed in some messages are also aligned with the keys used for lookup. - Reconstruction of values has been fixed for: - `table.padding` - `buffer_editor` - `hooks.command_not_found` - `datetime_format` (partial solution) - Fix validation of `table.padding` input so value is not set (and underflows `usize` causing `table` to run forever with negative values) - New proper types for settings. Fully validated enums instead of strings: - `config.edit_mode` -> `EditMode` - Don't fall back to vi-mode on invalid string - `config.table.mode` -> `TableMode` - there is still a fall back to `rounded` if given an invalid `TableMode` as argument to the `nu` binary - `config.completions.algorithm` -> `CompletionAlgorithm` - `config.error_style` -> `ErrorStyle` - don't implicitly fall back to `fancy` when given an invalid value. - This should also shrink the size of `Config` as instead of 4x24 bytes those fields now need only 4x1 bytes in `Config` - Completely removed macros relying on the scope of `Value::into_config` so we can break it up into smaller parts in the future. - Factored everything into smaller files with the types and helpers for particular topics. - `NuCursorShape` now explicitly expresses the `Inherit` setting. conversion to option only happens at the interface to `reedline`		2023-11-08 20:31:30 +01:00
