# Description
Before this PR, errors without error codes are printed somewhat
strangely, with the `×` and the description being printed on the same
line as the `Error:` text:
Error: × Invalid literal
╭─[entry #1:1:2]
1 │ "\z"
· ─┬─
· ╰── unrecognized escape after '\' in string
╰────
This PR adds a default error code for the different error types:
Error: nu::parser::error
× Invalid literal
╭─[entry #1:1:2]
1 │ "\z"
· ─┬─
· ╰── unrecognized escape after '\' in string
╰────
While maybe not as informative as a proper error code, it makes
`GenericError`s and other things which don't have error codes look a lot
nicer.
It would be nicer if we could just set `diagnostic(code:
"nu:🐚:error")` at the top of `ShellError`, but unfortunately you
can't set a "default" at the `enum` level and then override it in the
variants. @cptpiepmatz mentioned he might change miette's derive macro
to accommodate this, in that case we can switch the approach here.
# User-Facing Changes
* Errors without error codes now have a default error code corresponding
to from which part of Nushell the error occurred (shell, parser,
compile, etc)

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.
