习惯了php中的var_dump()函数，而如今写lua的时候总习惯使用var_dump()函数，于是就自己动手写了一个类似功能的var_dump()函数。
复制代码 代码如下:
function var_dump(data, max_level, prefix)
if type(prefix) ~= "string" then
prefix = ""
end
if type(data) ~= "table" then
print(prefix .. tostring(data))
else
print(data)
if max_level ~= 0 then
local prefix_next = prefix .. " "
print(prefix .. "{")
for k,v in pairs(data) do
io.stdout:write(prefix_next .. k .. " = ")
if type(v) ~= "table" or (type(max_level) == "number" and max_level <= 1) then
print(v)
else
if max_level == nil then
var_dump(v, nil, prefix_next)
else
var_dump(v, max_level - 1, prefix_next)
end
end
end
print(prefix .. "}")
end
end
end
