Workspace loading: 0 / 0 #981

arnoson · 2022-03-10T14:28:17Z

I'm trying to use your language server with codemirror 6. But somehow the only message I get is "Workspace loading: 0 / 0". I Use the same setup with monaco editor and it works (https://github.com./arnoson/monaco-lua-example).

From the message I guess that the editor file isn't really synchronized with the language server. I have a test setup here: https://github.com./arnoson/codemirror-lua

I tried to investigate the problem myself but I can't figure out whats missing.
Do you have any idea what the problem could be?

Your version is 2.5.0-dev, please upgrade to latest (2.6.7)

EDIT:
Don't use / as your rootUri, I will scan this folder to find out lua files!
See https://github.com./sumneko/lua-language-server/wiki/Why-scanning-home-folder%3F

I updated to 2.6.7 and removed the rootUri but it still shows the loading message

Later on I want to open two or more files at the same time with codemirror so I guess I need some kind of virtual workspace uri?

The easiest way is to put them in the same folder.

I updated to 2.6.7 and removed the rootUri but it still shows the loading message

I will test this case

I didn't commit yet, will do it now. Thank your for looking into this!

sumneko · 2022-03-10T18:39:23Z

Is that all you have in your log?

EDIT:
Please run the languager-server with command param --rpclog, then provide your new log.

arnoson · 2022-03-10T18:56:46Z

Updated the example (had to manually change the code mirror language server plugin to not send the workspace)
Here is the service log with --rpclog:

Thanks for your test, it seems that the server send the request of workspace/configuration to client, but client never responsed it.
This caused the server to keep waiting for the response.

arnoson · 2022-03-10T19:21:53Z

I just looked up what the monaco language server plugin does differently and it seems it is just answering with empty results:
{"id":10,"jsonrpc":"2.0","method":"workspace/configuration","params": ...
{"jsonrpc":"2.0","id":10,"result":[null,null,null,null,null]}
So I guess in order to get this to work code mirrors plugin should behave similary.
Thank you for your time! I'll try to fix this on the plugin

sumneko · 2022-03-10T19:25:35Z

https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#requestMessage

It says:

A request message to describe a request between the client and the server. Every processed request must send a response back to the sender of the request.

So the client could answering empty results (or anything else), but the client should not silent.

arnoson · 2022-03-10T20:08:26Z

It is finally working! Indeed the client didn't answer any requests, so simply replying with null did the trick. Thank you so much for your help!

QuantumKuba · 2023-07-14T01:36:58Z

If anyone came here looking for a solution with this being an issue in Neovide. I added this to my init.lua config and it's gone.

local on_attach = require("plugins.configs.lspconfig").on_attach
local capabilities = require("plugins.configs.lspconfig").capabilities

local lspconfig = require "lspconfig"

lspconfig.lua_ls.setup {
  on_attach = on_attach,
  capabilities = capabilities,
  settings = {
    Lua = {
      diagnostics = {
        globals = { "vim" },
      },
      workspace = {
        library = {
          [vim.fn.expand "$VIMRUNTIME/lua"] = true,
          [vim.fn.expand "$VIMRUNTIME/lua/vim/lsp"] = true,
        },
      },
    },
  },
}
