# Emacs Module in Rust [![crates.io](https://meritbadge.herokuapp.com/emacs)](https://crates.io/crates/emacs) [![doc.rs](https://docs.rs/emacs/badge.svg)](https://docs.rs/emacs/) [![Build Status](https://travis-ci.org/ubolonton/emacs-module-rs.svg?branch=master)](https://travis-ci.org/ubolonton/emacs-module-rs)

[User Guide](https://ubolonton.github.io/emacs-module-rs/) | [Example](https://github.com/ubolonton/magit-libgit2)

This provides a high-level binding to `emacs-module`.
Code for a minimal module looks like this:

```rust
extern crate libc;

use emacs;
use emacs::{Env, CallEnv, Result, Value};

emacs::emacs_plugin_is_GPL_compatible!();
emacs::emacs_module_init!(init);

fn init(env: &Env) -> Result<Value> {
    fn hello(env: &CallEnv) -> Result<Value> {
        let name: String = env.parse_arg(0)?;
        env.message(&format!("Hello, {}!", name))
    }

    emacs::emacs_export_functions! {
        env, "greeting-", {
            "say-hello" => (hello, 1..1)
        }
    }

    env.provide("greeting")
}
```

``` emacs-lisp
(require 'greeting)
(greeting-say-hello "Emacs")
```


## Live Reloading

Emacs does not support unloading modules. Live reloading thus requires a custom module loader. [rs-module](rs-module) is one such loader (which itself is a module that must be loaded by Emacs's normal loading mechanism). See [load.sh](bin/load.sh).

## Sample Modules

[test-module](test-module) uses most of the provided features.

## Development

- Building:
    ```shell
    cargo build --all
    ```
- Testing:
    ```shell
    bin/test.sh
    ```
- Continuous testing (requires `cargo-watch`):
    ```shell
    cargo watch -x 'build --all' -s bin/test.sh
    ```
