LSP server
The extension starts the powang LSP server automatically. The server requires Python 3.12+ and the powang repository on the Python path.
Configure the Python interpreter in your VS Code settings:
{
"powang.server.pythonPath": "python"
}
If Python is not on your PATH, set the full path:
{
"powang.server.pythonPath": "C:/Python312/python.exe"
}
The server script (powang_lsp.py) is expected to be at <powang_repo>/tools/powang_lsp.py. Set powang.server.repositoryPath to the Powang repository root if it is not your workspace. Set the powang.server.extraArgs setting to pass additional arguments.
