I've been working on streaming and pipeline interruption lately. It was bothering me that checking ctrl+c (something we want to do often) always requires a bunch of boilerplate like: ```rust use std::sync::atomic::Ordering; if let Some(ctrlc) = &engine_state.ctrlc { if ctrlc.load(Ordering::SeqCst) { ... ``` I added a helper method to cut that down to: ```rust if nu_utils::ctrl_c::was_pressed(&engine_state.ctrlc) { ... ```
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.
