LSP‐AI for Ace‐linters

Integrating lsp-ai Language Server with Ace Linters

Introduction

The LSP-AI language server provides advanced AI-assisted code analysis features like autocompletion, which enhance the Ace Editor environment for various programming languages.

Installation

1. Prerequisites:

   • Ensure you have Rust installed on your system. You can install Rust using rustup. This will include Cargo, the Rust package manager.
   • ace-linters ^1.2.3

2. Install LSP-AI Language Server: Use Cargo to install the lsp-ai language server. Depending on your system requirements, you can choose to install it with different features:

   • Basic Installation:

     cargo install lsp-ai

   • With llama_cpp Support: This is needed if you want to leverage AI models for code completion.

     cargo install lsp-ai --features llama_cpp

   • With metal and llama_cpp for MacOS: Recommended for users on MacOS with Metal support.

     cargo install lsp-ai --features "llama_cpp metal"

   • With cuda and llama_cpp for Nvidia GPUs: Recommended for users with Nvidia GPUs on Linux.

     cargo install lsp-ai --features "llama_cpp cuda"

   For detailed installation options and troubleshooting, visit the installation guide.

3. Running the Language Server: Ensure that the LSP-AI language server is running on the specified WebSocket port. For setting up the WebSocket server for LSP-AI, you can use tools like Language Server WebSocket Bridge for integrating multiple language servers.

Configuration

To integrate the lsp-ai language server with Ace Linters, configure your Ace Editor environment to connect to the lsp-ai language server via WebSocket. Here’s an example configuration:

// defaultGenerationConfiguration - (https://github.com/SilasMarvin/lsp-ai/wiki/Configuration)
// you will need OPENAI_API_KEY in env or use "auth_token" instead of "auth_token_env_var_name"
const defaultServerConfiguration =
    {
        "memory": {
            "file_store": {}
        },
        "models": {
            "model1": {
                "type": "open_ai",
                "chat_endpoint": "https://api.openai.com/v1/chat/completions",
                "model": "gpt-3.5-turbo-0125",
                "auth_token_env_var_name": "OPENAI_API_KEY"
            }
        },
        "completion": {
            ...defaultGenerationConfiguration
        }
    }
const serverData = {
    module: () => import("ace-linters/build/language-client"),
    modes: "javascript",
    type: "socket",
    socket: new WebSocket("ws://localhost:3030/lsp-ai"),
    initializationOptions: defaultServerConfiguration
}
