NAME

String::Trim - trim whitespace from your strings

CONTENTS

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).
