SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a ready-to-run blueprint for implementing a Language Server Protocol backend to enable robust editor integration with the NovelSaga codebase, including document handling, server capabilities, and asynchronous operations.

Core Features & Use Cases

  • LSP protocol implementation for robust editor communication and feature support.
  • Document synchronization, capability negotiation, and server lifecycle management.
  • Real-world use cases include implementing hover, completion, diagnostics, and formatting for the NovelSaga project.

Quick Start

Start the LSP server using the provided start() entry point and connect a client to exercise text document sync and capabilities.

FAQPage Schema
How do I implement a Language Server Protocol backend in Rust for editor integration?▼

Document synchronization in an LSP backend requires handling text document sync events and maintaining state asynchronously using Arc and tokio. The server manages lifecycle events and capability negotiation to keep editors updated.

Does tower_lsp support asynchronous safety patterns for language server development?▼

The LSP backend supports implementing hover, completion, diagnostics, and formatting features for the NovelSaga project. These capabilities are exposed through document handlers and capability negotiation during server initialization.

What's the best way to start a language server using tokio and tower_lsp?▼

The best way to start a language server is to use the provided start() entry point to initialize the backend and connect a client. This exercises text document sync and capabilities using tower_lsp traits and tokio.

Why does my LSP backend fail capability negotiation during server initialization?▼

To add diagnostics to your LSP backend, implement the relevant document handlers within the language server capabilities using tower_lsp traits. This enables the server to publish diagnostics during text document synchronization over the protocol.
