# Description Fixes #11267 Shifting by a `shift >= num_bits` is undefined in the underlying operation. Previously we also had an overflow on negative shifts for the operators `bit-shl` and `bit-shr` Furthermore I found a severe bug in the implementation of shifting of `binary` data with the commands `bits shl` and `bits shr`, this categorically produced incorrect results with shifts that were not `shift % 4 == 0`. `bits shr` also was able to produce outputs with different size to the input if the shift was exceeding the length of the input data by more than a byte. # User-Facing Changes It is now an error trying to shift by more than the available bits with: - `bit-shl` operator - `bit-shr` operator - command `bits shl` - command `bits shr` # Tests + Formatting Added testing for all relevant cases
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.
