closes #9111 # Description this pr improves parsing of values with units (`filesizes`, `durations` and any other **future values**) by: 1. allowing underscores in the value part ```nu > 42kb # okay > 42_sec # okay > 1_000_000mib # okay > 69k_b # not okay, underscores not allowed in the unit ``` 2. improving error messages involving these values ```nu > sleep 40-sec # before Error: nu::parser::parse_mismatch × Parse mismatch during operation. ╭─[entry #42:1:1] 1 │ sleep 40-sec · ──┬── · ╰── expected duration with valid units ╰──── # now Error: × duration value must be a number ╭─[entry #41:1:1] 1 │ sleep 40-sec · ─┬─ · ╰── not a number ╰──── ``` 3. unifying parsing of these values. now all of these use one function # User-Facing Changes filesizes and durations can now have underscores for readability
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.
