Accustomed to the Var_dump () function in PHP, and now writing Lua is always used to use the Var_dump () function, so I wrote a similar function of the var_dump () function.

Copy Code code as follows:

function Var_dump (data, max_level, prefix)
If type (prefix) ~= "string" Then
prefix = ""
If type (data) ~= "table" then
Print (prefix. ToString (data))
Print (data)
If Max_level ~= 0 Then
Local prefix_next = prefix. "    "
Print (prefix. "{")
For k,v in pairs (data) does
Io.stdout:write (Prefix_next. K..) " = ")
If Type (v) ~= "table" or (type (max_level) = = "Number" and Max_level <= 1) Then
Print (v)
if Max_level = = Nil Then
Var_dump (V, Nil, prefix_next)
Var_dump (V, MAX_LEVEL-1, Prefix_next)
Print (prefix. "}")
