{ 1->true 2->{ 1->nest } x->7 }

nice! would be a great addition to the pico8 api. tables are a pain to debug.

I imagine a lot of us have made something similar. I have a ton of pretty-printing stuff. Lua's string-ifying isn't the greatest in the first place, and even then, Pico-8 doesn't provide its full facilities. Pretty inconvenient when you have to debug with print(). It'd be nice if there was better native support.

Thank you for your code. While debugging I was looking for a function that would do the exact same thing.
I took your code and improved upon it.
-- converts anything to string, even nested tables
function tostring(any)
if (type(any)~="table") return tostr(any)
local str = "{"
for k,v in pairs(any) do
if (str~="{") str=str..","
str=str..tostring(k).."="..tostring(v)
end
return str.."}"
end |
This will print like this
> t = {5, {c="b"}, 'a', true}
> print(tostring(t))
{1=5,2={c=b},3=a,4=true} |
