Hi,
I wonder what idioms are available to loop through
the lines stored in a scalar variable. I guess I'm
looking for something analogous to these idioms
for files and arrays respectively:
while(<FH>) {
# do stuff
}
foreach (@array) {
# do stuff
}
When I had to do this I split the scalar in an
array:
@array = split "\n", $scalar;
foreach (@array) {
# do stuff
}
What would be some other ways to do this? (This is
purely curiosity.)
I suggest:
while ($str =~ /(.*?\n|.+\z)/g) {
my $line = $1;
:
:
}
