String::Trim - trim whitespace from your strings
print "Do it? ";
trim(my $response = <>);
String::Trim trims whitespace off your strings. chomp trims only $/ (typically, that's newline), but trim will trim all leading and trailing whitespace.
Returns the string with all leading and trailing whitespace removed. Trimming undef gives you undef. Alternatively, you can trim in-place.
my $var = ' my string ';
my $trimmed = trim($var);
trim also knows how to trim an array or arrayref:
my @to_trim = (' one ', ' two ', ' three ');
my @trimmed = trim(@to_trim);
my $trimmed = trim(\@to_trim);
trim is often used by beginners, who may not understand how to spin their own. While String::Util does have a trim function, it depends on Debug::ShowStuff, which depends on Taint, which fails the test suite, and doesn't appear to be maintained. This module installs, is actively maintained, and has no non-core dependencies.
Other options include Text::Trim and String::Strip (which is implemented in XS, and is therefore likely to be very fast, but requires a C compiler).
