Koto is a simple and expressive programming language, usable as an extension

language for [Rust][rust] applications, or as a standalone scripting language.

## Info

- [About Koto](crates/cli/docs/about.md)

- [Koto Language Guide](crates/cli/docs/language_guide.md)

- [CLI Docs](crates/cli/docs/cli.md)

- [Online Playground][playground]

- [Example Rust application with Koto bindings](crates/koto/examples/poetry/)

## Development

The top-level [justfile](./justfile) contains some useful commands for working

with the repo, for example `just checks` which runs all available checks and

tests.

After installing [just][just], you can run `just setup` to install additional

dependencies for working with the `justfile` commands.

## MSRV

Koto is under active development, and tested against the latest stable release

of Rust.
