pyright + ruff

[predmijat]

Is there a way to use ruff with pyright? I read that ruff should probably be used with an LSP, but I've only found examples for pylsp, not pyright.

[alphastrata]

just change the args from the pylsp to ruff & make sure it's installed on path (both ruff and ruff-lsp)

Hey now that Helix support multi LSP. my setting are working well with Pyright + ruff as LSP and black + ruff as formatter

[language-server.pyright]
command = "pyright-langserver"
args = ["--stdio"]

[language-server.pyright.config]
python.analysis.venvPath = "."
python.analysis.venv = ".venv"
python.analysis.lint = true
python.analysis.inlayHint.enable = true
python.analysis.autoSearchPaths = true
python.analysis.diagnosticMode = "workspace"
python.analysis.useLibraryCodeForType = true
python.analysis.logLevel = "Error"
python.analysis.typeCheckingMode = "off"
python.analysis.autoImoprtCompletion = true
python.analysis.reportOptionalSubscript = false
python.analysis.reportOptionalMemberAccess = false


[language-server.ruff]
command = "ruff"
args = ["server", "-q", "--preview"] 


[[language]]
name = "python"
scope = "source.python"
injection-regex = "python"
file-types = ["py", "pyi", "py3", "pyw", "ptl", "rpy", "cpy", "ipy", "pyt", { glob = ".python_history" }, { glob = ".pythonstartup" }, { glob = ".pythonrc" }, { glob = "SConstruct" }, { glob = "SConscript" }]
shebangs = ["python"]
roots = ["pyproject.toml", "setup.py", "poetry.lock", "pyrightconfig.json", "requirements.txt", ".venv/"]
comment-token = "#"
language-servers = [ {name = "pyright", except-features=["diagnostics"]}, "ruff" ]
indent = { tab-width = 4, unit = "    " }
auto-format = true
formatter =  { command = "bash", args = ["-c", "ruff format --line-length 80 -q . && black --line-length 80 -q -"] }

Simply out of curiosity: what's the reason for using both Ruff and Black for formatting? Doesn't Ruff's formatter more or less mirror Black already?

Also, check out https://github.com/DetachHead/basedpyright if you haven't already. It's like pyright but without the arbitrary restrictions on features that for some reason belong in Pylance instead.

ruff format just deleted all my code while formatting with helix I think it doesn't support stdout format yet

[lemontheme]

Sure it does! Just need to add a - to the args list, which pipes the stdin in.

formatter = { command = "ruff", args = ["format", "-" ] }

[vazw]

oh that it's 😆🙏

[schlich]

a lot of people are gonna run into this problem, i think it's worth adding to the wiki

This is my current setup that works nicely, in case anybody wants to see a full example:

[[language]]
name = "python"
language-id = "python"
roots = ["pyproject.toml", "setup.py", "poetry.lock", ".git", ".jj", ".venv/"]
language-servers = ["ruff", "pyright"]
auto-format = true
# formatter = { command = "black", args = ["--quiet", "-", "--line-length=80"] }
formatter = { command = "ruff", args = ["format", "-" ] }
file-types = ["py", "ipynb"]
comment-token = "#"
shebangs = ["python"]

[language-server.pyright]
command = "pyright-langserver"
args = ["--stdio"]

[language-server.ruff]
command = "ruff"
args = ["server"]
environment = { "RUFF_TRACE" = "messages" }

[language-server.ruff.config.settings]
lineLength = 80
logLevel = "debug"

[language-server.ruff.config.settings.lint]
select = ["E", "F", "W", "B", "I", "RUF", "N", "LOG", "ERA", "W", "D", "UP", "ANN", "ASYNC", "S", "RET", "TCH", "ARG", "PTH", "DOC"]
preview = true

[language-server.ruff.config.settings.format]
preview = true
quote-style = "double"
docstring-code-format = true
indent-style = "space"

How did you guys installed pyright / ruff lsp's?

[nrbnlulu]

ended up using pipx ubuntu has no package for ruff lsp

[j-dominguez9]

You're probably better off using just ruff, as it has the lsp server + linter and formatter, as noted in their readme:

Note

As of Ruff v0.4.5, Ruff ships with a built-in language server written in Rust: ⚡ ruff server ⚡

ruff server supports the same feature set as ruff-lsp, but with superior performance and no installation required. ruff server was marked as stable in Ruff v0.5.3

And you can install it with a curl command.

ruff does not do type checking like pyright does. while you can use ruff server instead of ruff-lsp it is not a replacement for pyright

who said it was? 👀

for sure nobody, just clarifying for folks at home 😉
