gollark: Really, it should just require the dependencies it needs itself.
gollark: I was just saying that the API initialization is really a bit pointlessly complex.
gollark: Who?
gollark: ```lualocal w = require("w") -- allows interaction with krist websocket api (for realtime data) local r = require("r") -- makes http requests easier local k = require("k") -- the krist api itself local jua = require("jua") -- makes events easier os.loadAPI("json.lua") -- to parse data returned by the krist api local await = jua.await -- initialise w.lua, r.lua and k.lua r.init(jua) w.init(jua) k.init(jua, json, w, r)```Wow, they really overcomplicated this.
gollark: and again, what do you have against text chat?
