Autocompletion does not support `module.common`

[LJSonik]

init.lua:

local greetings = require 'greetings'

greetings. -- No autocompletion for 'hi' and 'hello'

greetings/greetings.lua:

local m = require 'greetings.common'

dofile 'greetings/hi.lua'
dofile 'greetings/hello.lua'

return m

greetings/hi.lua:

local m = require 'greetings.common'

function m.hi()
    print 'hi'
end

greetings/hello.lua:

local m = require 'greetings.common'

function m.hello()
    print 'hello'
end

The hi and hello functions do not appear in the autocompletion list.

use ---@class to mark them.

init.lua:

local greetings = require 'greetings'

greetings. -- got 'hi' and 'hello'

greetings/greetings.lua:

---@class greetings
local m = require 'greetings.common'

dofile 'greetings/hi.lua'
dofile 'greetings/hello.lua'

return m

greetings/hi.lua:

---@class greetings
local m = require 'greetings.common'

function m.hi()
    print 'hi'
end

greetings/hello.lua:

---@class greetings
local m = require 'greetings.common'

function m.hello()
    print 'hello'
end
