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).
