How to dump all _G table content - lua

Question

i want to dump _G table. in _G table has other table also dump (inline table). and i want have a good format. i have a example but use it dump _G table have some problem
function print_table(node)
-- to make output beautiful
local function tab(amt)
local str = ""
for i=1,amt do
str = str .. "\t"
end
return str
end
local cache, stack, output = {},{},{}
local depth = 1
local output_str = "{\n"
while true do
local size = 0
for k,v in pairs(node) do
size = size + 1
end
local cur_index = 1
for k,v in pairs(node) do
if (cache[node] == nil) or (cur_index >= cache[node]) then
if (string.find(output_str,"}",output_str:len())) then
output_str = output_str .. ",\n"
elseif not (string.find(output_str,"\n",output_str:len())) then
output_str = output_str .. "\n"
end
-- This is necessary for working with HUGE tables otherwise we run out of memory using concat on huge strings
table.insert(output,output_str)
output_str = ""
local key
if (type(k) == "number" or type(k) == "boolean") then
key = "[" ..type(k).. ":"..tostring(k).."]"
else
key = "['"..type(k).. ":"..tostring(k).."']"
end
if (type(v) == "number" or type(v) == "boolean") then
output_str = output_str .. tab(depth) .. key .. " = "..tostring(v)
elseif (type(v) == "table") then
output_str = output_str .. tab(depth) .. key .. " = {\n"
table.insert(stack,node)
table.insert(stack,v)
cache[node] = cur_index+1
break
else
output_str = output_str .. tab(depth) .. key .. " = '"..tostring(v).."'"
end
if (cur_index == size) then
output_str = output_str .. "\n" .. tab(depth-1) .. "}"
else
output_str = output_str .. ","
end
else
-- close the table
if (cur_index == size) then
output_str = output_str .. "\n" .. tab(depth-1) .. "}"
end
end
cur_index = cur_index + 1
end
if (size == 0) then
output_str = output_str .. "\n" .. tab(depth-1) .. "}"
end
if (#stack > 0) then
node = stack[#stack]
stack[#stack] = nil
depth = cache[node] == nil and depth + 1 or depth - 1
else
break
end
end
-- This is necessary for working with HUGE tables otherwise we run out of memory using concat on huge strings
table.insert(output,output_str)
output_str = table.concat(output)
print(output_str) end
this is result log

i don't why how to fix this function

Answer 1

I use this:
-- deep dumps the contents of the table and it's contents' contents
function deepdump( tbl )
local checklist = {}
local function innerdump( tbl, indent )
checklist[ tostring(tbl) ] = true
for k,v in pairs(tbl) do
print(indent..k,v,type(v),checklist[ tostring(tbl) ])
if (type(v) == "table" and not checklist[ tostring(v) ]) then innerdump(v,indent.." ") end
end
end
print("=== DEEPDUMP -----")
checklist[ tostring(tbl) ] = true
innerdump( tbl, "" )
print("------------------")
end
