What are the steps to reproduce this issue?

i tried to use IntelliJ IDEA to edit the hammerspoon lua files

What happens?

one problem is, that it marks me some of the hs. as unknown variables and also some more errors because of unknown types

this also show me an error:

  local win = hs.window.focusedWindow()
  local app = win:application()
  local currentFrame = win:frame()
  local wins = app:allWindows()
  for _, childwin in ipairs(wins) do
    childwin:setFrame(currentFrame) -- No such member 'setFrame' found on type 'V'
local function Set (list)
  local set = {}
  for _, l in ipairs(list) do set[l] = true end -- error: No such indexer '[V]' found on type 'table'
  return set

What were you expecting to happen?

  • no errors
  • a way to include the hammerspoon source files

Any logs, error output, etc?

  • No such member 'setFrame' found on type 'V'
  • No such indexer '[V]' found on type 'table'

Any other comments?

Luanalysis is fairly opinionated. You can certainly turn inspections off but you’ll lose out on the type safety benefits. In this case you probably want something like:

---@generic V
---@param list V[]
local function Set (list)
    ---@type table<V, nil | true>
    local set = {}
    for _, l in ipairs(list) do set[l] = true end
    return set

the creator of EmmyLua explained why he not direct use the files in App folder - but maybe there is an other idea how to get it working 😃

Why not just add /Applications/ as an external library to the lsp config?

Simply adding the hammerspoon extensions directory as an external library doesn’t work for a couple of reasons:

class instances, constructors and function return would not get proper autocompletion _coresetup populates the hs[string] table with all modules. LSP servers have a hard time dealing with this and think all functions/methods/variables anywhere are valid auto completions for every module. With the generated stubs, auto completion works for all HS functionality.
