lsp-types 0.6.0

Zero-dependency Python library for Language Server Protocol types

LSP Types

Publish the excellent work of Sublime LSP as a PyPI package.

LSP Types is a Python package that aims to provide a fully typed interface to Language Server Protocol (LSP) interactions. It can be used to simply utilize the types, or to interact with an LSP server over stdio.

It is a goal to maintain zero-dependency status for as long as possible.

Installation

pip install lsp-types

Usage

Using the LSP types:

import lsp_types

# Use the types

Using an LSP session through stdio:

from lsp_types.session import LSPSession, ProcessLaunchInfo

process_info = ProcessLaunchInfo(cmd=[
    "pyright-langserver", "--stdio"
])

async with LSPSession(process_info) as session:
    # Initialize the session
    ...

    # Grab a typed listener
    diagnostics_listener = session.notify.on_publish_diagnostics(timeout=1.0)

    # Send a notification
    await session.notify.did_open_text_document(...)

    # Wait for diagnostics to come in
    diagnostics = await diagnostics_listener

Development

• Requires Python 3.11+.
• Requires poetry for dev dependencies.
