mruby-sys

Low level mruby bindings for rust

The crate will build mruby and statically link it into your Rust application. Currently it uses mruby 2.0.1 included as a submodule in the vendor/ directory.

This is currently a very early WIP so very basic things might not work, or worse they may appear to work but do very unsafe things. There is a simple hello world test that runs on my machine.

How it works

Most of the work happens in the build.rs script which:

1. Copies the mruby source in the vendor/ directory into the target/ directory
2. Builds mruby in the target/ directory using mruby's minirake based build system
3. Uses bindgen to generate Rust bindings based on the wrapper.h file in the include/ directory. These bindings and their tests are rexported out in src/lib.rs.

Todo list:

• Enable support for choosing gems
• Support toolchains besides clang
• Reasonable support for passing along compiler flags to the minirake build, especially debug vs release builds.
• Web Assembly?!?
• Reasonable support for other mruby build options, i.e. building with no gem support
