How to change string.gmatch returning memory address?

#1

Whenever I try to print string.gmatch() it prints an unreadable memory address.
Is there a way to make it print/return something that I can actually read?
Example:
Code:
print(string.gmatch("Hello", "%a+"))
Output:
function: 0x4bdedf296e67671d

It’s returning an iterator function, I think you should look at the string.gmatch documentation. Try string.match instead?

Thank you, but how do you read the data in the iterator function? Autocomplete is not showing any methods or attributes.

#4

It’s a function, so it can’t be indexed, and therefore autocomplete shows nothing for it. I think you put it in pairs() in a for loop to get all the matches in the string.

#5

string.gmatch() returns a function. In order to read the data you need to do something like this:

for k in string:gmatch(".") do
     print(k)
end
