requests-lsp

This package provides an adapter for debugging Language Server Protocol with requests.

The protocol is a JSON-RPC 2.0 with added Content-Length header.

The project started as a fork of https://github.com/paivett/requests-curl by @paivett, but since then there is almost no shared code. requests-lsp raw sockets for communication insted of PyCURL.

Installation

Examples may run well without installation, but just in case - clone this project and run

python setup.py install

Usage

Import the adapter, mount it and use requests.get to send JSON to LSP server.

import requests
from requests_lsp import LSPAdapter

with requests.Session() as session:
    session.mount("lsp://", LSPAdapter())

    response = session.get("lsp://127.0.0.1:9084", json={"id": "1", "method": "initialize"})
    print(response.json())

The example is in sendfile.py file in repository, tested with Solargraph Ruby LSP server. Use runserver.sh script with podman to run it in debug mode for experiments.

On successful request you will see the server capabilities reply, and this output in Solargraph logs.

Running tests

There are no LSP tests for now. There were files from requests-curl, which uses pytest for testing.
