Patterns in Lua with space

How could I use string.gmatch(text, pattern) to do this:

text = "Hello.%23 Awesome7^.."
pattern = --what to put here?
for word in string.gmatch(text, pattern) do
  print(word)
end
--Result
>test
Hello.%23
Awesome7^..
>

I have been using "%w+%p", but this results in:

>test
Hello.
%
23
Awesome7^
.
.

Which is not the desired result.

Note: I have not tested this exact string, it could vary... but still, does not create the desired result

Solution

  • From your example, every word contains no spaces, and are separated by spaces, so the simplest pattern is "%S+":

    text = "Hello.%23 Awesome7^.."
pattern = "%S+"
for word in string.gmatch(text, pattern) do
  print(word)
end

    "%s" matches a space character, "%S" matches a non-space character.
