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

Commencez par le module init.lua et le rockspec fournis, puis reproduisez les deux motifs de require dans LuaLS avec le paramètre workspace.library indiqué. Suivez la manière dont les chemins require dynamiques sont résolus et dont les champs des tables retournées reçoivent leurs types ; le travail est terminé lorsque ui. propose des champs connus et typés pour les modules exportés par 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 ?
