No completion of built-in modules

[wbthomason]

I cannot get any completions from built-in modules (e.g. os, io, etc.). Completion works for tables I define, and most of the rest of the LS functionality works fine, so I don't think I have a configuration error. All that seems to fail is getting completions from these built-in modules. I'm using coc.nvim with the instructions given for EmmyLua-LS here: https://github.com/neoclide/coc.nvim/wiki/Language-servers#lua - am I missing something? Thanks!

any updates?

I'v found the stdFolder option in LuaLanguageServer.kt, but it does not work:

call coc#config('languageserver.EmmyLua', {
        \   'command': &shell,
        \   'args': [&shellcmdflag, 'java -cp EmmyLua-LS-all.jar com.tang.vscode.MainKt'],
        \   'filetypes': ['lua'],
        \   'initializationOptions': {
        \     'stdFolder': 'path_to_this_repo/std/Lua54',
        \   },
        \ })

EDIT:

• the stdFolder is the solution, but you must use file:// as prefix
• I'v created a repo to make life easier: https://github.com/ZSaberLv0/EmmyLua_stdFolder

I just wanted to post that I am interested in this as well and would like for the server to handle the built-in modules. I am very appreciative of this project and all of the hard work this team has done. Thank you.

there's a workaround, copy the contents of https://github.com/EmmyLua/IntelliJ-EmmyLua/tree/master/src/main/resources/std/Lua54 to your project (or to one of your project's sub dir)

but obviously that's not very convenient

any updates?

I'v found the stdFolder option in LuaLanguageServer.kt, but it does not work:

You need to specify it as a URI, e.g.

"stdFolder": "file:///C:/EmmyLua-LanguageServer/res/std"

[ZSaberLv0]

"stdFolder": "file:///C:/EmmyLua-LanguageServer/res/std"

it works!

How do I pass stdFolder to emmy in spacemacs on macos?

use emmylua-analyzer instead of this
