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).
Install with pipx is recommended:
pipx install multi-lsp-proxy
Pip also works:
pip install multi-lsp-proxy
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"
