分享一个打印Table表的函数

[冷颜的午睡日常]

先将代码放这里：

function dump_value_(v)
	if type(v) == "string" then
		v = "\"" .. v .. "\""
	end
	return tostring(v)
end

function split(input, delimiter)
	input = tostring(input)
	delimiter = tostring(delimiter)
	if (delimiter == "") then return false end
	local pos, arr = 0, {}
	for st, sp in function() return string.find(input, delimiter, pos, true) end do
		table.insert(arr, string.sub(input, pos, st - 1))
		pos = sp + 1
	end
	table.insert(arr, string.sub(input, pos))
	return arr
end

function trim(input)
	return (string.gsub(input, "^%s*(.-)%s*$", "%1"))
end

function dump(value, desciption, nesting)
	print(value, desciption, nesting)
	if type(nesting) ~= "number" then nesting = 3 end

	local lookupTable = {}
	local result = {}

	local traceback = split(debug.traceback("", 2), "\n")
	-- print("dump from: " .. trim(traceback[3]))

	local function dump_(value, desciption, indent, nest, keylen)
		desciption = desciption or "<var>"
		local spc = ""
		if type(keylen) == "number" then
			spc = string.rep(" ", keylen - string.len(dump_value_(desciption)))
		end
		if type(value) ~= "table" then
			result[#result +1 ] = string.format("%s%s%s = %s", indent, dump_value_(desciption), spc, dump_value_(value))
		elseif lookupTable[tostring(value)] then
			result[#result +1 ] = string.format("%s%s%s = *REF*", indent, dump_value_(desciption), spc)
		else
			lookupTable[tostring(value)] = true
			if nest > nesting then
				result[#result +1 ] = string.format("%s%s = *MAX NESTING*", indent, dump_value_(desciption))
			else
				result[#result +1 ] = string.format("%s%s = {", indent, dump_value_(desciption))
				local indent2 = indent.."    "
				local keys = {}
				local keylen = 0
				local values = {}
				for k, v in pairs(value) do
					keys[#keys + 1] = k
					local vk = dump_value_(k)
					local vkl = string.len(vk)
					if vkl > keylen then keylen = vkl end
					values[k] = v
				end
				table.sort(keys, function(a, b)
					if type(a) == "number" and type(b) == "number" then
						return a < b
					else
						return tostring(a) < tostring(b)
					end
				end)
				for i, k in ipairs(keys) do
					dump_(values[k], k, indent2, nest + 1, keylen)
				end
				result[#result +1] = string.format("%s}", indent)
			end
		end
	end
	dump_(value, desciption, "- ", 1)

	for i, line in ipairs(result) do
		print(line)
	end
end

使用方法： dump(table表)
能够打印出完整的一个表。适用于全部表，能解决打印表但是只打印出内存地址。

我是这么用的，缺点就是不便于阅读

local function log(content)
	if typeof(content) == "table" then
		return HttpService:JSONEncode(content)
	else
		return content
	end
end
