# Description - `where` used to be able to filter using stored closures at some point using a flag. > #5955 - This was later removed and `filter` command added to cover the use case. > #7365 This PR once again allows using `where` with closures stored in variables. ```nushell let cond = { $in mod 2 == 0 } 1..10 | where $cond # => ╭───┬────╮ # => │ 0 │ 2 │ # => │ 1 │ 4 │ # => │ 2 │ 6 │ # => │ 3 │ 8 │ # => │ 4 │ 10 │ # => ╰───┴────╯ let nested = {cond: { $in mod 2 == 0 }} 1..10 | where $nested.cond # => ╭───┬────╮ # => │ 0 │ 2 │ # => │ 1 │ 4 │ # => │ 2 │ 6 │ # => │ 3 │ 8 │ # => │ 4 │ 10 │ # => ╰───┴────╯ ``` This does not interfere with using `$it` or one of its fields as the condition. ```nushell [[name state]; [foo true] [bar false] [baz true] [quox false]] | where $it.state # => ╭───┬──────┬───────╮ # => │ # │ name │ state │ # => ├───┼──────┼───────┤ # => │ 0 │ foo │ true │ # => │ 1 │ baz │ true │ # => ╰───┴──────┴───────╯ ``` This change obsoletes `filter`, deprecate it in the future? # User-Facing Changes # Tests + Formatting Added examples and tests. - 🟢 toolkit fmt - 🟢 toolkit clippy - 🟢 toolkit test - 🟢 toolkit test stdlib # After Submitting --------- Co-authored-by: Bahex <17417311+Bahex@users.noreply.github.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.
