//! # onagre-launcher-toolkit
//!
//! A toolkit to write pop-launcher client and plugin.
//!
//! ## Crates
//! - **[`launcher`]:** re-export the pop-launcher crate, containing all the IPC message struct and
//! some utility functions to locate plugins.
//! - **[`service`]:** re-export the pop-launcher-service crate, containing deserializable plugin config struct.
//! This is useful if your client needs to read user defined plugins configs.
//! - **[`plugins`]:** re-export pop-launcher-plugins which defines all the default pop-launcher plugins.
//! Useful if your client needs to read default plugin configs
//!
//! ## Writing a plugin
//!
//! Add the following to your Cargo.toml :
//!
//! ```toml
//! [dependencies]
//! tokio = { version = "1.18.2", features = ["rt"] }
//! onagre-launcher-toolkit = { git = "https://github.com/pop-os/launcher" }
//! ```
//!
//! And implement the [`PluginExt`] trait:
//!
//! [`PluginExt`]: plugin_trait::PluginExt
//!
//! ```rust
//! use pop_launcher_toolkit::launcher::{Indice, PluginResponse, PluginSearchResult};
//! use pop_launcher_toolkit::plugin_trait::{async_trait, PluginExt};
//! use pop_launcher_toolkit::plugins;
//!
//! // The plugin struct, here it holds the search result
//! pub struct MyPlugin {
//! data: Vec<String>
//! }
//!
//! #[async_trait]
//! impl PluginExt for MyPlugin {
//!
//! // Define the name of you plugin, this will be used
//! // to generate a logfile in $XDG_STATE_HOME at runtime.
//! fn name(&self) -> &str {
//! "my_awesome_plugin"
//! }
//!
//! // Respond to `pop-launcher` 'search' query
//! async fn search(&mut self, query: &str) {
//! // `pop-launcher` dispatches request to plugins according to the regex defined in
//! // the `plugin.ron` config file, here we get rid of the prefix
//! // before processing the request.
//! let query = query.strip_prefix("plug ").unwrap();
//!
//! // Iterate through our internal search results with their indices.
//! let search_results = self.data.iter()
//! .enumerate()
//! .filter(|(idx, data)| data.contains(query));
//!
//! // Send our search results to `pop-launcher` using their indices as id.
//! for (idx, search_result) in search_results {
//! self.respond_with(PluginResponse::Append(PluginSearchResult {
//! id: idx as u32,
//! name: search_result.clone(),
//! description: "".to_string(),
//! keywords: None,
//! icon: None,
//! exec: None,
//! window: None,
//! })).await;
//! }
//!
//! // tell `pop-launcher` we are done with this request
//! self.respond_with(PluginResponse::Finished).await;
//! }
//!
//! // Respond to `pop-launcher` 'activate' query
//! async fn activate(&mut self, id: Indice) {
//! // Get the selected entry
//! let entry = self.data.get(id as usize).unwrap();
//! // Here we use xdg_open to run the entry but this could be anything
//! plugins::xdg_open(entry);
//! // Tell pop launcher we are done
//! self.respond_with(PluginResponse::Finished).await;
//! }
//!
//! // Respond to `pop-launcher` 'close' request.
//! async fn quit(&mut self, id: Indice) {
//! self.respond_with(PluginResponse::Close).await;
//! }
//! }
//!
//! #[tokio::main(flavor = "current_thread")]
//! pub async fn main() {
//!
//! // Here we declare our plugin with dummy values, and never mutate them.
//! // In a real plugin we would probably use some kind of mutable shared reference to
//! // update our search results.
//! let mut plugin = MyPlugin {
//! data: vec!["https://crates.io".to_string(), "https://en.wikipedia.org".to_string()],
//! };
//!
//! /// If you need to debug your plugin or display error messages use `tcracing` macros.
//! tracing::info!("Starting my_awsome_plugin");
//!
//! // Call the plugin entry point function to start
//! // talking with pop_launcherc
//! plugin.run().await;
//! }
//! ```
