Overview

emacs-module-rs provides high-level Rust binding and tools to write Emacs's dynamic modules. It is easy to use if you know either Rust or Emacs.

It currently supports stable Rust, Emacs 25/26, macOS/Linux.

Known Issues

There is a bug (see issue #1) with Emacs 26 on Linux that prevents it from loading any dynamic modules (even those written in C), if:

  • Emacs is built without thread support.
  • The OS is Ubuntu 16.04 (Xenial).

Setting up
  • Install the Rust toolchain with rustup.
  • Make sure that your Emacs was compiled with module support. Check that module-file-suffix is not nil, and the function module-load is defined.
