# Description This PR: - Removes the lazy_command, expr_command macros and migrates the commands that were utilizing them. - Removes the custom logic in DataFrameValues::is_equals to use the polars DataFrame version of PartialEq - Adds examples to commands that previously did not have examples or had inadequate ones. NOTE: A lot of examples now have a `polars sort` at the end. This is needed due to the comparison in the result. The new polars version of equals cares about the ordering. I removed the custom equals logic as it causes comparisons to lock up when comparing dataframes that contain a row that contains a list. I discovered this issue when adding examples to `polars implode`
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.
