Hi, I think it's a stupid question but I can't wrap my head around this: I guess I am missing something trivial.
I need to sanitize two user inserted strings:
sanitize A should keep every alphanumeric character, spaces and punctuation
sanitize B should keep only lowercase a-z: no spaces, no punctuation, no numbers
I wonder why my gsub never works:
this should be my implementation of sanitize B, where the output in my dreams should be "elephant"
local testring = "134àelephantù#.!$ 4"
print("TEST STRING", testring)
