Using with neodev

[s1341]

Hi,

I'm attempting to use lsp-zero with the neodev plugin (https://github.com/folke/neodev.nvim), but can't get completion/lsp functionality for the vim global object or plugins to work.

I know lsp-zero has the nvim_workspace function, but it lacks some features (like api function documentation).

Any hints on how to get these plugins to play nicely with each other?

Thanks,

I tried this and it worked.

require('neodev').setup({})

local lsp = require('lsp-zero')

lsp.preset('recommended')
lsp.setup()

My init.lua is in ~/.config/nvim/. Does that make a diffference?

[VonHeikemen]

I don't think so. That's the right folder.

Ok I figured it out. lua-language-server wasn't running because I'm on nixos and an interpreter patch was needed.

[s1341]

For those interested, the problem was that mason.nvim downloads lua-language-server as a binary, and that binary can't run as is on nixos. See mason-org/mason.nvim#428 (comment) for a fix.

Hi, it works for me (neodev gives the completion) but it disables the command LspZeroFormat:

E5108: Error executing lua: Command not found: LspZeroFormat
stack traceback:
[C]: at 0x56474ff97860

[VonHeikemen]

what about the LSP keybindings? do they work?

[ricardovg4]

gq to format a single line is working. However, LspZeroFormat disappears, and also the diagnostics with gl seem to have vanished. My config file for neodev.lua is:

require("neodev").setup({
})

local lspconfig = require('lspconfig')

lspconfig.sumneko_lua.setup({
settings = {
Lua = {
completion = {
callSnippet = "Replace"
},
workspace = {
checkThirdParty = false,
}
}
}
})

I also tried doing the setup on neodev.lua like this, but then completions on neodevs part don't work:

require("neodev").setup({
})

local lspconfig = require('lsp-zero')
lspconfig.use('sumneko_lua', {
settings = {
Lua = {
completion = {
callSnippet = "Replace"
},
workspace = {
checkThirdParty = false,
}
}
}
})

It seems that placing the config of neodev.lua inside the config for lspzero.lua and before lsp.setup() has corrected the issue. Thank you for your last comment.

I actually have kind of the opposite issue. I setup sumneko using lsp-zero along with custom settings, for example settings.Lua.diagnostics.workspaceDelay = -1 to disable workspace diagnostics. However, running neodev.setup() overwrites this configuration, regardless of where I call the function.

I already raised an issue on the neodev repo(folke/neodev.nvim#97) and tested with manual nvim-lspconfig configuration on a minimal config, where this does not seem to be an issue. It seems neodev needs to run before the lsp servers get setup, which might be a potential cause of this issue. Is there a way to run pre-setup hooks for lsp-zero?

[VonHeikemen]

There are no pre-setup hooks. If you want to run something "pre-setup", just do it before calling lsp.setup().

[vishalbalaji]

I feel stupid. Turned out that there was just a duplicate neodev.setup call after lsp.setup that I missed. Thanks for replying and sorry for wasting your time 🙏.
