# Description Currently, if a custom completer returns a record containing an `options` field, but these options don't specify `case_sensitive`, `case_sensitive` will be true. This PR instead makes the default value whatever the user specified in `$env.config.completions.case_sensitive`. The match algorithm option already does this. `positional` is also inherited from the global config, although user's can't actually specify that one themselves in `$env.config` (I'm planning on getting rid of `positional` in a separate PR). # User-Facing Changes For those making custom completions, if they need matching to be done case-sensitively and: - their completer returns a record rather than a list, - and the record contains an `options` field, - and the `options` field is a record, - and the record doesn't contain a `case_sensitive` option, then they will need to specify `case_sensitive: true` in their custom completer's options. Otherwise, if the user sets `$env.config.completions.case_sensitive = false`, their custom completer will also use case-insensitive matching. Others shouldn't have to make any changes. # Tests + Formatting Updated tests to check if `case_sensitive`. Basically rewrote them, actually. I figured it'd be better to make a single helper function that takes completer options and completion suggestions and generates a completer from that rather than having multiple fixtures providing different completers. # After Submitting Probably needs to be noted in the release notes, but I don't think the [docs](https://www.nushell.sh/book/custom_completions.html#options-for-custom-completions) need to be updated.
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
