# Description we talked about this before in some meetings so i thought, why not? the hope is that these constants do not require Rust code to be implemented and that this move will make the Rust source base a bit smaller 🤞 # User-Facing Changes mathematical constants (e, pi, tau, phi and gamma) are now in `std math` rather than `math` ## what can be done ```nushell > use std; $std.math > use std math; $math > use std *; $math ``` will all give ``` ╭───────┬────────────────────╮ │ GAMMA │ 0.5772156649015329 │ │ E │ 2.718281828459045 │ │ PI │ 3.141592653589793 │ │ TAU │ 6.283185307179586 │ │ PHI │ 1.618033988749895 │ ╰───────┴────────────────────╯ ``` and the following will work too ```nushell > use std math E; $E 2.718281828459045 ``` ```nushell > use std math *; $GAMMA 0.5772156649015329 ``` ## what can NOT be done looks like every export works fine now 😌 # Tests + Formatting # After Submitting
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.
