NAME
String::Trim - trim whitespace from your strings
VERSION
version 0.005
SYNOPSIS
use String::Trim;
print "Do it? ";
trim(my $response = <>);
print "'$response'\n";
DESCRIPTION
String::Trim
trims whitespace off your strings. chomp trims only $/
(typically, that's newline), but trim
will trim all leading and trailing whitespace.
FUNCTIONS
trim
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);
# OR
trim($var);
trim
also knows how to trim an array or arrayref:
my @to_trim = (' one ', ' two ', ' three ');
my @trimmed = trim(@to_trim);
# OR
trim(@to_trim);
# OR
my $trimmed = trim(\@to_trim);
# OR
trim(\@to_trim);
RATIONALE
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).
