Not working with pyright

[ashwinprasadme]

I'm trying to get this working with pyright.

I'm running the tests from the repo and added pyright start command, i.e., "pyright": ["pyright-langserver", "--stdio"]

The initialization is getting passed, i.e., tserver.wait_for_message_of_type(lsp.Initialized)

However, after that, I do not seem to receive any more responses from the server,

Diagnostic response is not received, even the hover methods do not seem to return anything.

diagnostics = tserver.wait_for_message_of_type(lsp.PublishDiagnostics)

Since I'm new to this, I thought someone can help me here. Please let me know, thank you!

I can look into this too, maybe in a few weeks, because I too would like to use pyright with sansio-lsp-client :)

Things I would try next:

• Try to get pyright to print some information to stderr (stdout is already used for emitting langserver events). Does it have a "verbose" flag or something?
• Print everything that the tests are sending and receiving, not as langserver events but as bytes.
• Try to get pyright to work with an editor or another lsp client library. Again, have a look at the sent and received data.

Thank you for your response. I shall look into this as well. I will let you know how it goes!

I'm unable to test this directly, however this discussion seems to attest that rootUri (which the tests use) is not supported by pyright.

It might be that we need to switch to using workspaceFolders in the tests to achieve full compatibility, as advised in the discussion I've linked.

[Akuli]

I'm new to workspaceFolders.

• Is it possible to provide both, so that no matter which one a langserver supports, it will work?
• If it is, should it be done in sansio-lsp-client or in other projects that use sansio-lsp-client?

Also, nice to see that you're still active :)

As it seems, the tests actually do set workspaceFolders, however it still seems to not work. I'll see if I can spin up something to test this first-hand.

I'm still alive and kicking! I've just been busy with university + being sick the past few weeks, thought I'd check out my notifications and stuff.

Also, the Raspberry Pi I run my ZNC bouncer on seems to have spontaneously died and I haven't had the time to try and fix it :\

[Akuli]

I now have a linode server that runs a game I made. We could set up a bouncer there if you want.

Here's something: I've noticed pyright-langserver sends a client/registerCapability request for workspace/didChangeWorkspaceFolders. The test infrastructure does nothing to handle this and so pyright itself may just be endlessly waiting for our reply to that request, leading it to not publish diagnostics.

[PurpleMyst]

Replying to the notification still seems to do nothing

This seems to be related to sending workspaceFolders in initialize. If you set that property to None, the tests seem to run.

pyright creates a default workspace for files that you haven't provided a workspace for.

I'll need to look further into how pyright handles workspaces and the like, but the fact that it works if you just don't send any workspaceFolders in initialization is a start.

Thanks! I just tested it and it works now, I'm able to get responses from the server as expected.
