# Description Bug fix: `PipelineData::check_external_failed()` was not preserving the original `type_` and `known_size` attributes of the stream passed in for streams that come from children, so `external-command | into binary` did not work properly and always ended up still being unknown type. # User-Facing Changes The following test case now works as expected: ```nushell > head -c 2 /dev/urandom | into binary # Expected: pretty hex dump of binary # Previous behavior: just raw binary in the terminal ``` # Tests + Formatting Added a test to cover this to `into binary`
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.
