Example:
use Validate::Hash;
my $vh = new Validate::Hash(
required => ['Fred', 'Wilma'],
optional => ['Barney', 'Betty'],
verify => {Barney => qr/\d+/,
Fred => qr/\w+/},
-errs => {illegal => "#KEY# is illegal",
required => "#KEY# is required!",
notmatch =>
"the value #KEY#, #VALUE#, doesn't match /#PATTER
+N#/",
-strict => 1,
);
my %hash = (Fred => 'A', Barney => 1);
$vh->valid(\%hash); # returns false,
$vh->get_error(); # returns 'Wilma is required!'

***** Summary
This module provides Object-Oriented way to validate the contents of a hash.
It should be useful for CGI-ish forms or for validating the arguments of functions.
Whatever floats your boat.
To install, just:
% perl Makefile.PL
% make
% make install
Validate::Hash is documented by its own POD. I suggest you read it by typing:
% perldoc Validate::Hash

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>

-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
