Swirl Language Server

Next Gen Language Server for Swirl written in C++. Currently only has dummy implementations for lsp methods.

Prerequisites

• A C++ compiler (e.g., g++, clang++)
• CMake (3.10 or higher)
• A JS runtime and package manager (We use Bun here)

Getting Started

1. Install Client Dependencies

bun install

2. Build the Language Server

This project uses CMake to build the C++ server. The executable will be created at build/swirl_lsp.

# Configure the build
cmake -B build -S .

# Compile the server
cmake --build build

3. Run

The main.ts script acts as a client that launches and communicates with the compiled server.

bun run main.ts

4. Integrate with VSCode

To use this language server in VSCode, you can set up a simple extension or use the vscode-languageclient library to connect to the server executable and communicate via stdio.
