# Description - this PR should close #10819 # User-Facing Changes Behaviour is similar to pre 0.86.0 behaviour of the cp command and should as such not have a user-facing change, only compared to the current version, were the option is readded. # After Submitting I guess the documentation will be automatically updated and as this feature is no further highlighted, probably, no more work will be needed here. # Considerations coreutils actually allows a third option: ``` pub enum UpdateMode { // --update=`all`, ReplaceAll, // --update=`none` ReplaceNone, // --update=`older` // -u ReplaceIfOlder, } ``` namely `ReplaceNone`, which I have not added. Also I think that specifying `--update 'abc'` is non functional.
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.
