autocompletion with love2d engine

[deb75]

Hello,

I build a game with the love2d engine. The game is written in lua so I tried to use emacs lsp-lua
with this lua language server.

Here is an example of a "hello world" game :

local love = require "love"

function love.draw()
   love.graphics.print("Hello World", 400, 300)
end

This "game" is run with the love engine : love.exe directory\where\is\the\file

The "require" line is not mandatory for the game to start, I put it because otherwise the lua language server
considers "love" as undefined. When I put it, I assume the lua language server picks up the "love.dll" which
is in the same directory as "love.exe".

However, autocompletion does not seem to work as for regular lua package. I noticed that I am only
proposed the "love" fields and functions which are already used in the script.

How can I improve this ?

The language server can only parse lua file, so I think maybe you should use a library file. For example, you can use Emmy Lua LOVE API, or you can use my fork which I think is much more complete than the original one and still under active maintenance.

Hi,

Thanks very much, I will try your fork as soon as possible.

i managed to get auto completion working using emacs.
these link helped.
https://github.com/LuaLS/lua-language-server/wiki/Libraries.
emacs-lsp/lsp-mode#2818

in the end i had to modify my emacs init file and add the workspace library like below.

(require 'ht)
(setq lsp-lua-workspace-library (ht ("~/.emacs.d/.cache/lsp/lua-language-server/meta/3rd/love2d/library/"  t)))

you can also place a .luarc.json configuration file in your project folder which also works

{
    "runtime.version": "LuaJIT",
    "workspace.library": [
        "${3rd}/love2d/library"
    ],
    "runtime.special":  {"love.filesystem.load" : "loadfile"}
}
