I am trying to find a regular expression that matches each line of an input
string but cannot find an expression that needs no additional checks. What I
have tried so far:
for line in str:gmatch("[^\n]+") do
matches not empty lines
for line in str:gmatch("([^\n]*)\n?") do
matches every line correctly BUT returns an empty string after the last
"123" results in
line = "123"
line = ""
I cannot get rid of the last match, so I wonder if there is an elegant
expression to match every line correctly, even empty lines and without adding
