//! ## Structure

//! ## structure

||||
//! be used to join workspaces or attach to buffers.

||||
//! To generate Operation Sequences use helper methods from the trait [buffer::OperationFactory].
|
||||
//!
|
||||
//! ## Features
|
||||
//! ## features
|
||||
//! * `proto` : include GRCP protocol definitions under [proto] (default enabled)
|
||||
//! * `global`: provide a lazy_static global INSTANCE in [instance::global]
|
||||
//! * `sync` : wraps the [instance::a_sync::Instance] holder into a sync variant: [instance::sync::Instance]
|
||||
//!
|
||||
//! ## Examples
|
||||
//! library can be used both sync and async depending on wether the `sync` feature flag has been
|
||||
//! enabled. a global `INSTANCE` static reference can also be made available with the `global`
|
||||
//! flag.
|
||||
//! ## examples
|
||||
//! while the [Client] itself is the core structure implementing all methods, plugins will mostly
|
||||
//! interact with [Instance] managers.
|
||||
//!
|
||||
//! ### Async
|
||||
//! ```rust,ignore
|
||||
//! async fn async_example() -> codemp::Result<()> {
|
||||
//! let session = codemp::Instance::default(); // create global session
|
||||
//! session.connect("http://alemi.dev:50051").await?; // connect to remote server
|
||||
//! ### async
|
||||
//! this library is natively async and thus async usage should be preferred if possible
|
||||
//!
|
||||
//! // join a remote workspace, obtaining a cursor controller
|
||||
//! let cursor = session.join("some_workspace").await?;
|
||||
//! cursor.send( // move cursor
|
||||
//! codemp::proto::CursorPosition {
|
||||
//! buffer: "test.txt".into(),
|
||||
//! start: Some(codemp::proto::RowCol { row: 0, col: 0 }),
|
||||
//! end: Some(codemp::proto::RowCol { row: 0, col: 1 }),
|
||||
//! }
|
||||
//! )?;
|
||||
//! let op = cursor.recv().await?; // listen for event
|
||||
//! println!("received cursor event: {:?}", op);
|
||||
//! ```rust,no_run
|
||||
//! use codemp::Controller;
|
||||
//! use codemp::buffer::OperationFactory;
|
||||
//!
|
||||
//! // attach to a new buffer and execute operations on it
|
||||
//! session.create("test.txt", None).await?; // create new buffer
|
||||
//! let buffer = session.attach("test.txt").await?; // attach to it
|
||||
//! buffer.send(buffer.insert("hello", 0))?; // insert some text
|
||||
//! if let Some(operation) = buffer.delta(4, "o world", 5) {
|
||||
//! buffer.send(operation)?; // replace with precision, if valid
|
||||
//! # async fn async_example() -> codemp::Result<()> {
|
||||
//! let session = codemp::Instance::default(); // create global session
|
||||
//! session.connect("http://alemi.dev:50051").await?; // connect to remote server

//! // join a remote workspace, obtaining a cursor controller

||||
//! codemp::proto::CursorPosition {
|
||||
//! buffer: "test.txt".into(),
|
||||
//! start: Some(codemp::proto::RowCol { row: 0, col: 0 }),
|
||||
//! end: Some(codemp::proto::RowCol { row: 0, col: 1 }),
|
||||
//! }
|
||||
//! assert_eq!(buffer.content(), "hello world");
|
||||
//! )?;
|
||||
//! let op = cursor.recv().await?; // listen for event
|
||||
//! println!("received cursor event: {:?}", op);
|
||||
//!
|
||||
//! Ok(())
|
||||
//! // attach to a new buffer and execute operations on it
|
||||
//! session.create("test.txt", None).await?; // create new buffer
|
||||
//! let buffer = session.attach("test.txt").await?; // attach to it
|
||||
//! buffer.send(buffer.insert("hello", 0))?; // insert some text
|
||||
//! if let Some(operation) = buffer.delta(4, "o world", 5) {
|
||||
//! buffer.send(operation)?; // replace with precision, if valid
|
||||
//! }
|
||||
//! assert_eq!(buffer.content(), "hello world");
|
||||
//! #
|
||||
//! # Ok(())
|
||||
//! # }
|
||||
//! ```
|
||||
//!
|
||||
//! ### Sync
|
||||
//! ### sync
|
||||
//! if async is not viable, including the feature `sync` will provide a sync-only Instance variant
|
||||
//!
|
||||
//! ```rust,ignore
|
||||
//! // activate feature "global" to access static CODEMP_INSTANCE
|
||||
//! use codemp::instance::global::INSTANCE;
|
||||
//! ```rust,no_run
|
||||
//! # use codemp::instance::sync::Instance;
|
||||
//! # use std::sync::Arc;
|
||||
//! # use codemp::Controller;
|
||||
//! #
|
||||
//! # fn sync_example() -> codemp::Result<()> {
|
||||
//! let session = Instance::default(); // instantiate sync variant
|
||||
//! session.connect("http://alemi.dev:50051")?; // connect to server
|
||||
//!
|
||||
//! fn sync_example() -> codemp::Result<()> {
|
||||
//! INSTANCE.connect("http://alemi.dev:50051")?; // connect to server
|
||||
//! let cursor = INSTANCE.join("some_workspace")?; // join workspace
|
||||
//! let (stop, stop_rx) = tokio::sync::mpsc::unbounded_channel(); // create stop channel
|
||||
//! Arc::new(cursor).callback( // register callback
|
||||
//! INSTANCE.rt(), stop_rx, // pass instance runtime and stop channel receiver
|
||||
//! | cursor_event | {
|
||||
//! println!("received cursor event: {:?}", cursor_event);
|
||||
//! }
|
||||
//! );
|
||||
//! // join remote workspace and handle cursor events with a callback
|
||||
//! let cursor = session.join("some_workspace")?; // join workspace
|
||||
//! let (stop, stop_rx) = tokio::sync::mpsc::unbounded_channel(); // create stop channel
|
||||
//! Arc::new(cursor).callback( // register callback
|
||||
//! session.rt(), stop_rx, // pass instance runtime and stop channel receiver
|
||||
//! | cursor_event | {
|
||||
//! println!("received cursor event: {:?}", cursor_event);
|
||||
//! }
|
||||
//! );
|
||||
//!
|
||||
//! Ok(())
|
||||
//! // attach to buffer and blockingly receive events
|
||||
//! let buffer = session.attach("test.txt")?; // attach to buffer, must already exist
|
||||
//! while let Ok(op) = buffer.blocking_recv(session.rt()) { // must pass runtime
|
||||
//! println!("received buffer event: {:?}", op);
|
||||
//! }
|
||||
//! #
|
||||
//! # Ok(())
|
||||
//! # }
|
||||
//! ```
|
||||
//!
|
||||
//! ### reference
|
||||
//! ### global
|
||||
//! if instantiating the [Instance] manager is not possible, adding the feature `global` will
|
||||
//! provide a static lazyly-allocated global reference.
|
||||
//!
|
||||
//! ```rust,no_run
|
||||
//! # use codemp::instance::sync::Instance;
|
||||
//! # use std::sync::Arc;
|
||||
//! use codemp::prelude::*; // prelude includes everything with "Codemp" in front
|
||||
//! # async fn global_example() -> codemp::Result<()> {
|
||||
//! CODEMP_INSTANCE.connect("http://alemi.dev:50051").await?; // connect to server
|
||||
//! let cursor = CODEMP_INSTANCE.join("some_workspace").await?; // join workspace
|
||||
//! while let Ok(event) = cursor.recv().await { // receive cursor events
|
||||
//! println!("received cursor event: {:?}", event);
|
||||
//! }
|
||||
//! #
|
||||
//! # Ok(())
|
||||
//! # }
|
||||
//! ```
