No autocomplete for the "submodules" of a library when those included from init.lua

Inizia con il modulo init.lua e il rockspec forniti, quindi riproduci i due pattern di require in LuaLS con l'impostazione workspace.library mostrata. Traccia come vengono risolti i percorsi dinamici di require e come i campi delle tabelle restituite ricevono i tipi; il lavoro è completato quando ui. offre campi noti e tipizzati per i moduli esportati da init.lua.

Dear developers, I've read similar existing issues but didn't find the answer.

I have a library (which I am the developer of) which has this structure:

and init.lua is

local UI = (...) .. '.'

return {
    Block     = require(UI .. 'Block'),
    Image     = require(UI .. 'Image'),
    Label     = require(UI .. 'Label'),
    Layout    = require(UI .. 'Layout'),
    Rectangle = require(UI .. 'Rectangle'),
    Stack     = require(UI .. 'Stack'),

    ImageButton = require(UI .. 'ImageButton'),
    TextField   = require(UI .. 'TextField'),

    utils     = require(UI .. 'utils')
}

and the rockspec contains this:

build = {
   type = 'builtin',
   modules = {
      ['likelihud']             = 'likelihud/init.lua',
      ['likelihud.Block']       = 'likelihud/Block.lua',
      ['likelihud.Image']       = 'likelihud/Image.lua',
      ['likelihud.Label']       = 'likelihud/Label.lua',
      ['likelihud.Layout']      = 'likelihud/Layout.lua',
      ['likelihud.Rectangle']   = 'likelihud/Rectangle.lua',
      ['likelihud.Stack']       = 'likelihud/Stack.lua',
      ['likelihud.ImageButton'] = 'likelihud/ImageButton.lua',
      ['likelihud.TextField']   = 'likelihud/TextField.lua',
      ['likelihud.utils']       = 'likelihud/utils.lua',
   },
}

So after install I have

Coc-config:

{
    "suggest.noselect": true,
    "Lua.workspace.library" : [
        "/usr/local/share/lua/5.1"
    ]
}

The problem

If I write

local Button = require('likelihud.ImageButton')

I get autocomplete for Button.

But if instead I do

local ui = require('likelihud')

I get only those fields when I do ui., but the fields are unknown. :

So the problem LSP doesn't resolve this (...) .. '.' inside init.lua. Should I somehow change how init.lua provides those files or how to fix that ?
