# Description
Nushell parser now reject comparison operator with 2 strings (e.g.
`"abc" < "cba"`). This pr fixes it.
## before
```nu
~
❯ "abc" < "bca"
Error: nu::parser::unsupported_operation
× less-than comparison is not supported on values of type string
╭─[entry #43:1:1]
1 │ "abc" < "bca"
· ──┬── ┬
· │ ╰── doesn't support this value
· ╰── string
╰────
~
❯ def foo []: nothing -> string { "abc" }
~
❯ (foo) < "bca"
Error: nu::parser::unsupported_operation
× less-than comparison is not supported on values of type string
╭─[entry #53:1:1]
1 │ (foo) < "bca"
· ──┬── ┬
· │ ╰── doesn't support this value
· ╰── string
╰────
```
## after
```nu
~
❯ "abc" < "bca"
true
~
❯ def foo []: nothing -> string { "abc" }
~
❯ (foo) < "bca"
true
```
# User-Facing Changes
Following pattern will be allowed.
| operator | type of lhs | type of rhs | result |
| -------- | ----------- | ----------- | ------ |
| `<` | string | string | bool |
| `<=` | string | string | bool |
| `>` | string | string | bool |
| `>=` | string | string | bool |
# Tests + Formatting
- [x] `cargo fmt --all -- --check` to check standard code formatting
(`cargo fmt --all` applies these changes)
- [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used`
to check that you're using the standard code style
- [x] `cargo test --workspace` to check that all tests pass (on Windows
make sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- [x] `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

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.
