Struct hexchat_plugin::PluginHandle

pub struct PluginHandle { /* fields omitted */ }

A hexchat plugin handle, used to register hooks and interact with hexchat.

Examples

use hexchat_plugin::{PluginHandle};

fn init(ph: &mut PluginHandle) {
    ph.register("myplug", "0.1.0", "my awesome plug");
}

Methods

impl PluginHandle

pub fn register(&mut self, name: &str, desc: &str, ver: &str)

Registers this hexchat plugin. This must be called exactly once when the plugin is loaded.

Panics

This function panics if this plugin is already registered.

Examples

use hexchat_plugin::PluginHandle;

fn init(ph: &mut PluginHandle) {
    ph.register("foo", "0.1.0", "my foo plugin");
}

pub fn get_name(&self) -> &str

Returns this plugin's registered name.

Panics

This function panics if this plugin is not registered.

pub fn get_description(&self) -> &str

Returns this plugin's registered description.

Panics

This function panics if this plugin is not registered.

pub fn get_version(&self) -> &str

Returns this plugin's registered version.

Panics

This function panics if this plugin is not registered.

pub fn ensure_valid_context<F, R>(&mut self, f: F) -> R where     F: FnOnce(EnsureValidContext) -> R,

Ensures the current context is valid.

Panics

This function may panic if it's called while hexchat is closing.

pub fn get_context(&mut self) -> Context

Returns the current context.

Note: The returned context may be invalid. Use set_context to check.

pub fn set_context(&mut self, ctx: &Context) -> bool

Sets the current context.

Returns true if the context is valid, false otherwise.

pub fn with_context<F, R>(     &mut self,     ctx: &Context,     f: F ) -> Result<R, InvalidContextError<F, R>> where     F: FnOnce(EnsureValidContext) -> R,

Do something in a valid context.

Note that this changes the active context and doesn't change it back.

Errors

Returns Err(InvalidContextError(f)) if the context is invalid. See set_context. Otherwise, calls f and returns Ok(its result).

Note that InvalidContextError contains the original closure. This allows you to retry.

pub fn hook_command<F>(     &mut self,     cmd: &str,     cb: F,     pri: i32,     help: Option<&str> ) -> CommandHookHandle where     F: Fn(&mut PluginHandle, Word, WordEol) -> Eat + 'static + RefUnwindSafe,

Sets a command hook.

Examples

use hexchat_plugin::PluginHandle;

fn register_commands(ph: &mut PluginHandle) {
    ph.hook_command("hello-world", |ph, arg, arg_eol| {
        ph.print("Hello, World!");
        hexchat_plugin::EAT_ALL
    }, hexchat_plugin::PRI_NORM, Some("prints 'Hello, World!'"));
}

pub fn hook_server<F>(&mut self, cmd: &str, cb: F, pri: i32) -> ServerHookHandle where     F: Fn(&mut PluginHandle, Word, WordEol) -> Eat + 'static + RefUnwindSafe,

Sets a server hook.

Examples

use hexchat_plugin::PluginHandle;

fn register_server_hooks(ph: &mut PluginHandle) {
    ph.hook_server("PRIVMSG", |ph, word, word_eol| {
        if word.len() > 0 && word[0].starts_with('@') {
            ph.print("We have message tags!?");
        }
        hexchat_plugin::EAT_NONE
    }, hexchat_plugin::PRI_NORM);
}

pub fn hook_server_attrs<F>(     &mut self,     cmd: &str,     cb: F,     pri: i32 ) -> ServerHookHandle where     F: Fn(&mut PluginHandle, Word, WordEol, EventAttrs) -> Eat + 'static + RefUnwindSafe,

Sets a server hook, with attributes.

pub fn hook_print<F>(&mut self, name: &str, cb: F, pri: i32) -> PrintHookHandle where     F: Fn(&mut PluginHandle, Word) -> Eat + 'static + RefUnwindSafe,

Sets a print hook.

Examples

use hexchat_plugin::PluginHandle;

fn register_print_hooks(ph: &mut PluginHandle) {
    ph.hook_print("Channel Message", |ph, arg| {
        if let Some(nick) = arg.get(0) {
            if *nick == "KnOwN_SpAmMeR" {
                return hexchat_plugin::EAT_ALL
            }
        }
        hexchat_plugin::EAT_NONE
    }, hexchat_plugin::PRI_NORM);
}

pub fn hook_print_attrs<F>(     &mut self,     name: &str,     cb: F,     pri: i32 ) -> PrintHookHandle where     F: Fn(&mut PluginHandle, Word, EventAttrs) -> Eat + 'static + RefUnwindSafe,

Sets a print hook, with attributes.

pub fn hook_timer<F>(&mut self, timeout: i32, cb: F) -> TimerHookHandle where     F: Fn(&mut PluginHandle) -> bool + 'static + RefUnwindSafe,

Sets a timer hook

Examples

use hexchat_plugin::PluginHandle;

fn register_timers(ph: &mut PluginHandle) {
    ph.hook_timer(2000, |ph| {
        ph.print("timer up!");
        false
    });
}

pub fn print(&mut self, s: &str)

Prints to the hexchat buffer.

pub fn get_info(&mut self, id: &InfoId) -> Option<String>

Returns information on the current context.

Note: InfoId::Libdirfs may return None or broken results if the result wouldn't be (valid) UTF-8.
