# Description This PR removes the required positional argument from `run-external` and `exec` in favor of the rest arguments, meaning lists of external commands can be spread directly into `run-external` and `exec`. This does have the drawback of making calling `run-external` and `exec` with no arguments a run-time error rather than a parse error, but I don't imagine that is an issue. Before (for both `run-external` and `exec`): ```nushell run-external # => Error: nu::parser::missing_positional # => # => × Missing required positional argument. # => ╭─[entry #9:1:13] # => 1 │ run-external # => ╰──── # => help: Usage: run-external <command> ...(args) . Use `--help` for more # => information. let command = ["cat" "hello.txt"] run-external ...$command # => Error: nu::parser::missing_positional # => # => × Missing required positional argument. # => ╭─[entry #11:1:14] # => 1 │ run-external ...$command # => · ▲ # => · ╰── missing command # => ╰──── # => help: Usage: run-external <command> ...(args) . Use `--help` for more # => information. run-external ($command | first) ...($command | skip 1) # => hello world! ``` After (for both `run-external` and `exec`): ```nushell run-external # => Error: nu:🐚:missing_parameter # => # => × Missing parameter: no command given. # => ╭─[entry #2:1:1] # => 1 │ run-external # => · ──────┬───── # => · ╰── missing parameter: no command given # => ╰──── # => let command = ["cat" "hello.txt"] run-external ...$command # => hello world! ``` # User-Facing Changes Lists can now be spread directly into `run-external` and `exec`: ```nushell let command = [cat hello.txt] run-external ...$command # => hello world! ``` # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting N/A
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.
