# Description `from ...` conversions pass along all metadata except `content_type`, which they set to `None`. ## Rationale `open`ing a file results in no `content_type` metadata if it can be parsed into a nu data structure, and using `open --raw` results in `content_type` metadata. `from ...` commands should preserve metadata ***except*** for `content_type`, as after parsing it's no longer that `content_type` and just structured nu data. These commands should return identical data *and* identical metadata ```nushell open foo.csv ``` ```nushell open foo.csv --raw | from csv ``` # User-Facing Changes N/A # Tests + Formatting - 🟢 toolkit fmt - 🟢 toolkit clippy - 🟢 toolkit test - 🟢 toolkit test stdlib # After Submitting N/A
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.
