[Docs] improve language server config instructions, including config examples for different editors

[neel04]

Hi, thank you for this amazing fork. Especially loving the inlay hints with python 😄

The docs mention a couple IDEs, but not helix - how exactly can you set it up in that editor?

For reference, in helix's languages.toml, I believe you can set the analysis options like this:

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

[language-server.basedpyright.config]

basedpyright.analysis.typeCheckingMode = "standard"
...
basedpyright.analysis.reportMissingTypeStubs = true
basedpyright.analysis.analyzeUnannotatedFunctions = true
basedpyright.analysis.venvPath = "/Users/neel/miniconda3/envs/react_jax"

However, how/why do we know that the toml key here happened to be basedpyright.analysis and not just specifying the config, like typeCheckingMode directly?

Plus for something like venvPath - it's not working for me, I have to activate the conda environment before I open helix in my shell to get it to work. So clearly, its the wrong key.

If you could document/explain what toml key corresponds to toggling what features, it would be really helpful for helix users setting it up, as they won't have to mess with the internal basedpyright.{json | toml} config.

Thank you so much! let me know if there's some other information you'd need from me.

cc @lemontheme who figured out the config options I'm using above :)

the language server specific options are documented here. not sure why some settings are under analysis but others aren't

Plus for something like venvPath - it's not working for me, I have to activate the conda environment before I open helix in my shell to get it to work. So clearly, its the wrong key.

try python.venvPath instead. for whatever reason i didn't update that one from python.venvPath to basedpyright.venvPath, maybe because of compatibility issues with the vscode python extension, i don't remember

[neel04]

I put it under the [language-server.basedpyright.config] as

python.venvPath = "/Users/me/miniconda3/envs/react_jax"

still doesn't work.

the language server specific options are documented here. not sure why some settings are under analysis but others aren't

Also, those are the pyright settings - not the basedpyright ones documented here. How do I configure those in my config?

[DetachHead]

the the way config is handled in (based)pyright is kind of a mess (#64). the code that reads the language server config is separate to the code that reads the pyproject.toml/pyrightconfig.json settings, but both those pages in the documentation are relevant to basedpyright, i just haven't updated all references to the name "pyright", which i guess adds to the confusion (#582)

can you see if setting venvPath and venv in pyproject.toml or pyrightconfig.json works? it would look something like this:

# pyproject.toml
[tool.basedpyright]
venvPath = "/Users/me/miniconda3/envs/react_jax"
venv = ".venv"

or

// pyrightconfig.json
{
    "venvPath": "/Users/me/miniconda3/envs/react_jax"
    "venv": ".venv"
}

note that this assumes your react_jax directory isn't the venv itself, but a directory that contains a .venv directory (i have no idea why it's like this and not just one setting...)

i also just noticed that the language server config doesn't have a python.venv option, no idea why that is either (#583)

sorry i'm probably just giving you more questions than answers lol

[neel04]

No thats the directory to a conda environment, so it doesn't have a .venv there.

And it doesn't make sense to use the toml/json files as I want this setting LSP wide - so it resolves to that conda environment no matter the context of the project/folder.

[DetachHead]

that's probably the issue then. i'm not familiar with conda but it sounds like the only way to get pyright to work with it is to activate the venv first

[neel04]

Cool, but what about basedpyright's own config settings? like changing reportPrivateImportUsage = false which is not a pyright config 🤔

[DetachHead]

you mean the new rules exclusive to basedpyright like reportPrivateLocalImportUsage? they are configured the same way as the rest of the diagnostic rules: basedpyright.analysis.reportPrivateLocalImportUsage

[neel04]

right so uh, that doesn't work at all for me...

where in my languages.toml for helix,

[language-server.basedpyright.config]
basedpyright.analysis.typeCheckingMode = "standard"
...
basedpyright.reportPrivateUsage = false

I've tried variants of this and none of them work

[DetachHead]

you need the analysis part:

[language-server.basedpyright.config]
basedpyright.analysis.typeCheckingMode = "standard"
...
basedpyright.analysis.reportPrivateUsage = false

if that's still not working, if you happened to add a basedpyright or pyright section in pyproject.toml or a pyrightconfig.json file like i mentioned earlier, try deleting them because you may be running into #513

if that still doesn't help, i might need a self-contained repro since i'm not familiar with conda or helix. the exact steps you took to set everything up if possible

also, which version of basedpyright are you using?

[neel04]

also, which version of basedpyright are you using?

The latest - I installed it yesterday from homebrew.

I think you can just spin up any environment, do:

brew install basedpyright
brew install helix
pip3 install jax ruff

and put this in the languages.toml:

~/.config/helix/languages.toml

```py [[language]] name = "python" scope = "source.python" injection-regex = "python" file-types = ["py","pyi","py3","pyw",".pythonstartup",".pythonrc"] shebangs = ["python"] roots = [".", "pyproject.toml", "pyrightconfig.json"] comment-token = "#" language-servers = ["basedpyright", "ruff"] indent = { tab-width = 4, unit = " " } auto-format = true [language.formatter] command = "ruff" [language.debugger] name = "debugpy" transport = "stdio" command = "python3" args = ["-m", "debugpy.adapter"] [[language.debugger.templates]] name = "source" request = "launch" completion = [ { name = "entrypoint", completion = "filename", default = "." } ] args = { mode = "debug", program = "{0}" } [language-server.basedpyright] command = "basedpyright-langserver" args = ["--stdio"] [language-server.basedpyright.config] basedpyright.analysis.typeCheckingMode = "standard" basedpyright.analysis.autoSearchPaths = true basedpyright.analysis.useLibraryCodeForTypes = true basedpyright.analysis.reportMissingTypeStubs = true basedpyright.analysis.analyzeUnannotatedFunctions = true basedpyright.analysis.strictParameterNoneValue = true basedpyright.analysis.reportImportCycles = true basedpyright.analysis.reportUnreachable = true basedpyright.analysis.reportPrivateUsage = false [language-server.ruff] command = "ruff-lsp" [language-server.ruff.config.settings] args = ["--ignore", "E402", "E731"] [language-server.ruff.config.settings.format] preview = true [[language]] name = "markdown" formatter = { command = 'prettier', args = ["--parser", "markdown"] } auto-format = true ```

helix's config.toml is irrelevant here as its only editor settings.

and then do, in a newly created py file:

import jax
jax.distributed.initialize()

No need to run it ofc, and see if it gives you a warning.

[DetachHead]

thanks, i'll play around with it and try to get back to you within a day or so. appreciate your patience, i know how much of a pain it is configuring stuff like this

[DetachHead]

sorry i dunno how i missed this. the issue was that you need to specify the diagnostic severity overrides under basedpyright.analysis.diagnosticSeverityOverrides. this works:

[language-server.basedpyright.config]
basedpyright.analysis.typeCheckingMode = "standard"
basedpyright.analysis.diagnosticSeverityOverrides.autoSearchPaths = true
basedpyright.analysis.diagnosticSeverityOverrides.useLibraryCodeForTypes = true
basedpyright.analysis.diagnosticSeverityOverrides.reportMissingTypeStubs = true
basedpyright.analysis.diagnosticSeverityOverrides.analyzeUnannotatedFunctions = true
basedpyright.analysis.diagnosticSeverityOverrides.strictParameterNoneValue = true
basedpyright.analysis.diagnosticSeverityOverrides.reportImportCycles = true
basedpyright.analysis.diagnosticSeverityOverrides.reportUnreachable = true
basedpyright.analysis.diagnosticSeverityOverrides.reportPrivateImportUsage = false

[neel04]

That works! How did you find that? and how can someone find it for other config settings as well 👍

[DetachHead]

it's mentioned in the docs for the language server settings, but it's easy to miss:

basedpyright.analysis.diagnosticSeverityOverrides [map]: Allows a user to override the severity levels for individual diagnostic rules. "reportXXX" rules in the type check diagnostics settings in configuration are supported. Use the rule name as a key and one of "error," "warning," "information," "true," "false," or "none" as value.

i should probably add some examples for how to configure these, including examples for different editors

[neel04]

That would be amazing 🔥 Thank you for such prompt responses, especially during a weekend. I appreciate you taking out the time here to fix silly problems. Would definitely recommend basedpyright to all my friends ;)

PS: The inlay hints work wonderfully well. Can't believe I lived so long without them

[DetachHead]

glad i could help, i'll keep this issue until i update the docs with helix (and other editor) specific examples

[summersz]

I am using basedpyright with helix and rye. It works fine until I add a [tool.basedpyright] section to myproject.toml to configure it, and then it reports missing imports. I have tried adding the venv and venvPath settings that were working with pyright but with or without them basedpyright is unable to resolve imports. Is there a helix or myproject.toml setting that I am missing?

[DetachHead]

can you send the full pyproject.toml?

[summersz]

It was an issue with having left my pyright config in. It works after I removed the tool.pyright section.

# [tool.pyright]
# exclude = [ ".venv" ]
# venvPath = "."
# venv = ".venv"

[tool.basedpyright]
venvPath = "."
venv = ".venv"

[DetachHead]

yeah there should be an error warning you about that (#614)
