multi-lsp-proxy

A barely working LSP Proxy to multiple language servers, to use multiple LSPs per language in editors that doesn't support multiple LSPs per language natively like Helix (version 22.12).

Installation

Install with pipx is recommended:

pipx install multi-lsp-proxy

Pip also works:

pip install multi-lsp-proxy

Usage

Usage: multi-lsp-proxy [OPTIONS] --config <CONFIG>

Options:
  -c, --config <CONFIG>      Configuration file path
  -l, --language <LANGUAGE>  Select language servers by programming language name
  -h, --help                 Print help
  -V, --version              Print version

To use with Helix, set the language-server option in languages.toml, below is an example for Python that enables both pyright-langserver and ruff-lsp:

# Helix languages.toml file
[[language]]
 name = "python"
 scope = "source.python"
 injection-regex = "python"
 file-types = ["py", "pyi"]
 shebangs = ["python"]
 roots = ["pyproject.toml", "setup.py", "Poetry.lock"]
 comment-token = "#"
 language-server = { command = "multi-lsp-proxy", args = ["--config", "/path/to/multi-lsp-config.toml"] }
 auto-format = false
 indent = { tab-width = 4, unit = "    " }
 config = {}

and configure multi-lsp-proxy in multi-lsp-proxy.toml

log-file = "/tmp/multi-lsp-proxy.log"

[[language]]
name = "python"
command = "pyright-langserver"
args = ["--stdio"]

[[language]]
name = "python"
command = "ruff-lsp"
