Registering a function as global variable setter.

[MikuAuahDark]

I'm working on an environment that has their global variable locked up (no global variable assignment is allowed). However, it provides export function. The export function has this signature:

---@param var string
---@param value any
---@param override boolean
function export(var, value, override)
	if _G[var] and not override then
		error("already assigned")
	end

	rawset(_G, var, value)
end

In the environment I'm working on, this is the only function to call to set global variable. However I don't seem able to find a way to tell LuaLS to treat export function as expansion of rawset(_G, ...).

export("foo", "bar")
print(foo) -- Warning: foo is not defined

rawset(_G, "baz", "qux")
print(baz) -- no warning

Is there a way to register custom global variable setter function?

Maybe you can write a plugin to transform the export call into a global setter?

Uh, no. The export is the function exposed to the Lua environment to set global variables.

tracking of the state of that in a function is difficult,so the lang-server does not support this very well
you can refer this disscussion and create an issue for it.
