Rust hexchat-plugin
===================
`hexchat-plugin` provides safe and rusty API bindings for developing native HexChat plugins.
Example plugin:
```rust
#[macro_use]
extern crate hexchat_plugin;
use hexchat_plugin::{Plugin, PluginHandle, InfoId};
use std::sync::Mutex;
use std::sync::Arc;
#[derive(Default)]
struct MyPlug {
// be careful with these: we don't want to move them into the hooks, as that would cause memory leaks!
// we can safely use Arc::downgrade on them, however!
cmutex: Arc<Mutex<Vec<hexchat_plugin::CommandHookHandle>>>,
smutex: Arc<Mutex<Vec<hexchat_plugin::ServerHookHandle>>>,
pmutex: Arc<Mutex<Vec<hexchat_plugin::PrintHookHandle>>>,
tmutex: Arc<Mutex<Vec<hexchat_plugin::TimerHookHandle>>>,
}
impl Plugin for MyPlug {
fn init(&self, ph: &mut PluginHandle, _arg: Option<&str>) -> bool {
ph.register("MyPlug", "Prints the old topic on topic change", "0.1.0");
ph.print("Loaded MyPlug 0.1.0");
let enabled = Arc::new(Mutex::new(false));
{
let flag = enabled.clone();
self.pmutex.lock().unwrap().push(ph.hook_print("Topic Change", move |ph, _word| {
if *flag.lock().unwrap() {
if let Some(topic) = ph.get_info(&InfoId::Topic) {
ph.print(&format!("\x0322*\t\x0329Previous topic:\x03 {}", topic));
}
}
hexchat_plugin::EAT_NONE
}, hexchat_plugin::PRI_NORM));
}
self.cmutex.lock().unwrap().push(ph.hook_command("PrintOldTopic", move |ph, _word, word_eol| {
match word_eol.get(1) {
Option::Some(&s) if s == "true" => {
ph.print("Set PrintOldTopic to true");
*enabled.lock().unwrap() = true;
}
Option::Some(&s) if s == "false" => {
ph.print("Set PrintOldTopic to false");
*enabled.lock().unwrap() = false;
}
Option::Some(_) => {
ph.print("Usage: /PrintOldTopic [true|false]");
}
Option::None => {
ph.print(&format!("PrintOldTopic: {}", *enabled.lock().unwrap()));
}
}
hexchat_plugin::EAT_ALL
}, hexchat_plugin::PRI_NORM, Some("Usage: /PrintOldTopic [true|false]")));
true // tells hexchat we have successfully initialized
}
}
hexchat_plugin!(MyPlug);
```
