Manual Reference Pages - STRING::TRIM (3)
String::Trim - trim whitespace from your strings
print "Do it? ";
trim(my $response = <>);
String::Trim trims whitespace off your strings. chomp trims only $/ (typically,
thats 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 doesnt 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).
