NAME

6       String::Trim - trim whitespace from your strings
7

VERSION

9       version 0.005
10

SYNOPSIS

12           use String::Trim;
13
14           print "Do it? ";
15           trim(my $response = <>);
16           print "'$response'\n";
17

DESCRIPTION

19       "String::Trim" trims whitespace off your strings. chomp trims only $/
20       (typically, that's newline), but "trim" will trim all leading and
21       trailing whitespace.
22

FUNCTIONS

24   trim
25       Returns the string with all leading and trailing whitespace removed.
26       Trimming undef gives you undef. Alternatively, you can trim in-place.
27
28           my $var     = ' my string  ';
29           my $trimmed = trim($var);
30           # OR
31           trim($var);
32
33       "trim" also knows how to trim an array or arrayref:
34
35           my @to_trim = (' one ', ' two ', ' three ');
36           my @trimmed = trim(@to_trim);
37           # OR
38           trim(@to_trim);
39           # OR
40           my $trimmed = trim(\@to_trim);
41           # OR
42           trim(\@to_trim);
43

RATIONALE

45       "trim" is often used by beginners, who may not understand how to spin
46       their own. While String::Util does have a "trim" function, it depends
47       on Debug::ShowStuff, which depends on Taint, which fails the test
48       suite, and doesn't appear to be maintained.  This module installs, is
49       actively maintained, and has no non-core dependencies.
50
51       Other options include Text::Trim and String::Strip (which is
52       implemented in XS, and is therefore likely to be very fast, but
53       requires a C compiler).
