Ian Manske 9996e4a1f8 Shrink the size of `Expr` (#12610 ) # Description Continuing from #12568, this PR further reduces the size of `Expr` from 64 to 40 bytes. It also reduces `Expression` from 128 to 96 bytes and `Type` from 32 to 24 bytes. This was accomplished by: - for `Expr` with multiple fields (e.g., `Expr::Thing(A, B, C)`), merging the fields into new AST struct types and then boxing this struct (e.g. `Expr::Thing(Box<ABC>)`). - replacing `Vec<T>` with `Box<[T]>` in multiple places. `Expr`s and `Expression`s should rarely be mutated, if at all, so this optimization makes sense. By reducing the size of these types, I didn't notice a large performance improvement (at least compared to #12568). But this PR does reduce the memory usage of nushell. My config is somewhat light so I only noticed a difference of 1.4MiB (38.9MiB vs 37.5MiB). --------- Co-authored-by: Stefan Holderbach <sholderbach@users.noreply.github.com>		2024-04-24 15:46:35 +00:00

Plugin Example

Crate with a simple example of the Plugin trait that needs to be implemented in order to create a binary that can be registered into nushell declaration list

`example config`

This subcommand demonstrates sending configuration from the nushell $env.config to a plugin.

To register from after building nushell run:

register target/debug/nu_plugin_example

The configuration for the plugin lives in $env.config.plugins.example:

$env.config = {
  plugins: {
    example: [
      some
      values
    ]
  }
}

To list plugin values run:
