# Description Fixes: #10450 This pr differentiating between `--x: bool` and `--x` Here are examples which demostrate difference between them: ```nushell def a [--x: bool] { $x }; a --x # not allowed, you need to parse a value to the flag. a # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a` ``` For boolean flag with default value, it works a little bit different to #10450 mentioned: ```nushell def foo [--option: bool = false] { $option } foo # output false foo --option # not allowed, you need to parse a value to the flag. foo --option true # output true ``` # User-Facing Changes After the pr, the following code is not allowed: ```nushell def a [--x: bool] { $x }; a --x ``` Instead, you have to pass a value to flag `--x` like `a --x false`. But bare flag works in the same way as before. ## Update: one more breaking change to help on #7260 ``` def foo [--option: bool] { $option == null } foo ``` After the pr, if we don't use a boolean flag, the value will be `null` instead of `true`. Because here `--option: bool` is treated as a flag rather than a switch --------- Co-authored-by: amtoine <stevan.antoine@gmail.com> |

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.
