🛠️ Setup Guide
1. Configure Language Servers
Install Required Language Servers from VS Code Marketplace: if you pull the docker image, these are already downloaded.
Python: Pylance and Python extension ( identifier : ms-python.vscode-pylance, ms-python.python)
Go: Go extension ( identifier : golang.go)
Language-Specific Setup: if you pull the docker image, these are already setted.
For Go:
Enable semantic tokenization in your VS Code settings.json:
{
"gopls": {
"ui.semanticTokens": true
}
}
[Optional] Project Compilation
While not required, compiling your project can improve error diagnosis and auto-fixing capabilities
Refer Experiment Setup
2. Configure LLM Settings
LSPAI supports multiple LLM providers. Configure your preferred option in VS Code settings:
Open VS Code Settings (Ctrl/Cmd + ,)
Configure LLM settings using one of these methods:
Option A: Through VS Code Settings UI
Search for "LSPAI" settings
Configure your preferred model and API keys
Option B: Direct JSON Configuration
Add the following to your VS Code User Settings (settings.json):
{
"LSPAI": {
"provider": "deepseek",
"model": "deepseek-chat", // Choose: // gpt-4o-mini"; // llama3-70b // deepseek-chat
"openaiApiKey": "your-api-key", // Required for OpenAI
"deepseekApiKey": "your-api-key", // Required for Deepseek
"localLLMUrl": "http://your-ollama-server:port", // Required for Ollama
"proxyUrl": "your-proxy-server" // Optional: Configure if using a proxy
}
}
The settings may be shaded, but don't worry, it is normal effect.
