//! # MultiPlayer Code Editing lib //! //! ![just a nice pic](https://alemi.dev/img/about-slice-3.jpg) //! //! > the core library of the codemp project, driving all editor plugins //! //! ## structure //! The main entrypoint is the [Client] object, that maintains a connection and can //! be used to join workspaces or attach to buffers. It contains the underlying [Workspace] and //! stores active controllers. //! //! Some actions will return structs implementing the [api::Controller] trait. These can be polled //! for new stream events ([api::Controller::poll]/[api::Controller::recv]), which will be returned in order. //! Blocking and callback variants are also implemented. The [api::Controller] can also be used to send new //! events to the server ([api::Controller::send]). //! //! Each operation on a buffer is represented as an [woot::crdt::Op]. The underlying buffer is a //! [WOOT CRDT](https://inria.hal.science/file/index/docid/71240/filename/RR-5580.pdf), //! but to use this library it's only sufficient to know that all WOOT buffers that have received //! the same operations converge to the same state, and that operations might not get integrated //! immediately but instead deferred until compatible. //! //! ## features //! * `api` : include traits for core interfaces under [api] (default enabled) //! * `woot` : include the underlying CRDT library and re-exports it (default enabled) //! * `proto` : include GRCP protocol definitions under [proto] (default enabled) //! * `client` : include the local [client] implementation (default enabled) //! //! ## examples //! most methods are split between the [Client] itself and the current [Workspace] //! //! ### async //! ```rust,no_run //! use codemp::api::{Controller, TextChange}; //! //! # async fn async_example() -> codemp::Result<()> { //! // creating a client session will immediately attempt to connect //! let mut session = codemp::Client::new("http://alemi.dev:50053").await?; //! //! // login first, obtaining a new token granting access to 'some_workspace' //! session.login( //! "username".to_string(), //! "password".to_string(), //! Some("some_workspace".to_string()) //! ).await?; //! //! // join a remote workspace, obtaining a workspace handle //! let workspace = session.join_workspace("some_workspace").await?; //! //! workspace.cursor().send( // move cursor //! codemp::proto::cursor::CursorPosition { //! buffer: "test.txt".into(), //! start: codemp::proto::cursor::RowCol { row: 0, col: 0 }, //! end: codemp::proto::cursor::RowCol { row: 0, col: 1 }, //! } //! )?; //! let op = workspace.cursor().recv().await?; // receive event from server //! println!("received cursor event: {:?}", op); //! //! // attach to a new buffer and execute operations on it //! workspace.create("test.txt").await?; // create new buffer //! let buffer = workspace.attach("test.txt").await?; // attach to it //! let local_change = TextChange { span: 0..0, content: "hello!".into() }; //! buffer.send(local_change)?; // insert some text //! let remote_change = buffer.recv().await?; // await remote change //! # //! # Ok(()) //! # } //! ``` //! //! it's always possible to get a [Workspace] reference using [Client::get_workspace] //! //! ### sync //! if async is not viable, a solution might be keeping a global tokio runtime and blocking on it: //! //! ```rust,no_run //! # use std::sync::Arc; //! # use codemp::api::Controller; //! # //! # fn sync_example() -> codemp::Result<()> { //! let rt = tokio::runtime::Runtime::new().unwrap(); //! let mut session = rt.block_on( // using block_on allows calling async code //! codemp::Client::new("http://alemi.dev:50051") //! )?; //! //! rt.block_on(session.login( //! "username".to_string(), //! "password".to_string(), //! Some("some_workspace".to_string()) //! ))?; //! //! let workspace = rt.block_on(session.join_workspace("some_workspace"))?; //! //! // attach to buffer and blockingly receive events //! let buffer = rt.block_on(workspace.attach("test.txt"))?; // attach to buffer, must already exist //! while let Ok(op) = rt.block_on(buffer.recv()) { // must pass runtime //! println!("received buffer event: {:?}", op); //! } //! # //! # Ok(()) //! # } //! ``` //! //! ## references //! //! ![another cool pic coz why not](https://alemi.dev/img/about-slice-2.png) //! //! check [codemp-vscode](https://github.com/codewithotherpeopleandchangenamelater/codemp-vscode) //! or [codemp-nvim](https://github.com/codewithotherpeopleandchangenamelater/codemp-nvim) //! or [codemp-server](https://github.com/codewithotherpeopleandchangenamelater/codemp-server) for //! reference implementations. //! //! keep track of feature completedness with the //!
