How to print any table when writing a mod: 2023-08-04 06:40:52

This prints any table (table, array and proxy objects).
The code is heavily modified from
https://stackoverflow.com/questions/41942289/display-contents-of-tables-in-lua#answer-41943392
https://www.warzone.com/wiki/Mod_API_Reference#Proxy_Objects
Thanks to Just_A_Dutchman_ https://www.warzone.com/Profile?p=42131172405&u=Just_A_Dutchman__1 for explaining why checking for proxyType on plain arrays gives error.

Usage:
tblprint(object);


Code:
local function p(obj, p2)
	function tprint(tbl, indent)
		if type(tbl) ~= 'table' then
			return tostring(tbl);
		end

		if not indent then
			indent = 0;
		end

		-- arrays dont have a proxy type
		if numKeys(tbl) ~= #tbl and tbl.proxyType then
			return DumpProxy(tbl, indent + 2);
		end

		local toprint = '{\r\n';
		indent = indent + 2;

		for k, v in pairs(tbl) do
			toprint = toprint .. string.rep(' ', indent)

			if type(k) == 'number' then
				toprint = toprint .. '[' .. k .. '] = ';
			elseif type(k) == 'string' then
				toprint = toprint  .. k ..  ' = ';
			end

			if type(v) == 'table' then
				if v.__proxyID then
					toprint = toprint .. DumpProxy(v, indent + 2) .. ',\r\n';
				else
					toprint = toprint .. tprint(v, indent + 2) .. ',\r\n';
				end
			elseif type(v) == 'string' then
				toprint = toprint .. '"' .. v .. '",\r\n';
			else
				toprint = toprint .. tostring(v) .. ',\r\n';
			end
		end

		toprint = toprint .. string.rep(' ', indent - 2) .. '}';

		return toprint;
	end

	function DumpProxy(obj, indent)
		if type(obj) ~= 'table' then
			return tostring(obj);
		end

		local str = '{';

		for _, key in pairs(obj.readableKeys) do
			if key ~= 'readableKeys' then
				str = str .. '\r\n' .. string.rep(' ', indent);
				if type(key) == 'string' then
					str = str .. key;
				else
					str = str .. '[' .. key .. ']';
				end

				str = str .. ' = ';

				local value = obj[key];

				if type(value) == 'table' then
					str = str .. tprint(value, indent);
				elseif type(value) == 'string' then
					str = str .. '"' .. value .. '"';
				else
					str = str .. tostring(value);
				end

				str = str .. ',';
			end
		end

		return str .. '\r\n' .. string.rep(' ', indent - 2) .. '}';
	end

	if type(obj) == 'table' then
		return tprint(obj, p2);
	else
		return tostring(obj);
	end
end

function tblprint(tbl)
	print(p(tbl));
end

function numKeys(tbl)
	local n = 0;

	for k, v in pairs(tbl) do
		n = n + 1;
	end

	return n;
end

Why does a print function have 100 lines?

Prints everything correctly indented and shows all keys and values, not just what the keys are.

Because all LUA containers are tables, and when you print a LUA table you get its memory address.

And everything the WZ api uses is tables inside tables inside tables, so its a pain to print anything useful.
