Beni

mruby toolchain monorepo — a Ruby gem that manages the mruby build chain and Rust crates that bind the mruby C API, extracted from the kobako project.

Status: under active development. The published 0.0.0 versions reserve the package names while the build chain and binding crates are extracted from kobako; no usable API ships yet.

Packages

Package	Registry	Role
beni gem	rubygems.org	mruby dependency manager — vendors mruby source, builds libmruby.a, future mrbgem management
beni-sys crate	crates.io	bindgen FFI surface over the mruby C API
beni crate	crates.io	typed Rust wrapper over beni-sys (magnus analog)

Toolchain

beni targets plain mruby and is not bound to WebAssembly. rust-toolchain.toml keeps wasm32-wasip1 only as a build-verification target for downstream wasi consumers (kobako). For that target the Rust channel and the wasi-sdk version move in lockstep (the wasm32-wasip1 crt1-command.o references __wasi_init_tp from Rust 1.96 onward; wasi-sdk 33's libc.a supplies that symbol) — bump the pair together, in both this repo and kobako. Host builds are unaffected by the pairing.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

The Rust crates live under crates/ in a Cargo workspace at the repo root; cargo check --workspace covers both.
