App-CacheEasy application-level caching

# in your class, stores in something like# ~/.parse_backpan_packages/cache/my $cache = App::Cache->new({ ttl => 60*60 });$cache->delete(’test’);my $data = $cache->get(’test’);my $code = $cache->get_code("code",

sub { $self->calculate() });my $html = $cache->get_url(

"http://www.google.com/");$cache->set(’test’, ’one’);$cache->set(’test’, { foo => ’bar’ });my $scratch = $cache->scratch;$cache->clear;

App-Cache

# in CPAN::Mini::Webservermy $cache = App::Cache->new({ ttl => 60 * 60 }

);my $parse_cpan_authors = $cache->get_code(

’parse_cpan_authors’,sub {

Parse::CPAN::Authors->new($authors_filename->stringify

)}

);

Crypt::Skip32::Base32Crockford

Crypt::Skip32 + Encode::Base32::Crockford =database record IDs in URLs

my $key = pack( ’H20’, "112233445566778899AA" );my $cipher = Crypt::Skip32::Base32Crockford->new($key);my $n = 3493209676;my $b32 = $cipher->encrypt_number_b32_crockford($n);# 1PT4W80my $m = $cipher->decrypt_number_b32_crockford($b32);# 3493209676

Email-Send-Gmail

Send Messages using Gmail

use Email::Send;use Email::Send::Gmail;use Email::Simple::Creator;

my $email = Email::Simple->create(header => [

From => ’magicmonitoring@gmail.com’,To => ’acme@astray.com’,Subject => ’Server down’,

],body => ’The server is down, panic!’,

);

Email-Send-Gmail

my $sender = Email::Send->new({

mailer => ’Gmail’,mailer_args => [

username => ’magicmonitoring@gmail.com’,password => ’XXXISABADPASSWORD’,

]}

);eval { $sender->send($email) };die "Error sending email: $@" if $@;

Games-GuessWordGuess the letters in a word (i. e. Hangman)

my $g = Games::GuessWord->new(file => "/path/to/wordlist"

);print "Score: " . $g->score . "\n";print "Chances: " . $g->chances . "\n";print "Answer: " . $g->answer . "\n";my @guesses = $g->guesses;$g->guess("t");# ...if ($g->won) {

print "You won!\n";$g->new_word;

}

HTML-Fraction

Encode fractions as HTML entities

my $fraction = HTML::Fraction->new;print $fraction->tweak($html);# 1/5 is ⅕

which is displayed as 1⁄5

Image-Imlib2-�umbnail

Generate a set of thumbnails of an image

my $t = Image::Imlib2::Thumbnail->new();foreach my $thumbnail

($t->generate( $image, $directory )) {my $name = $thumbnail->{name};my $width= $thumbnail->{width};my $height = $thumbnail->{height};my $type = $thumbnail->{type};my $filename = $thumbnail->{filename};print "$name/$type is $width x $height";print " at $filename\n";

}

Image-Imlib2-�umbnail

By default it generates thumbnails of the samedimension that Flickr generates:

Image-WorldMap

Create graphical world maps of data

use Image::WorldMap;my $map = Image::WorldMap->new("earth-small.png", "maian/8"

);$map->add(4.91, 52.35, "Amsterdam.pm");$map->add(-2.355399, 51.3828, "Bath.pm");$map->add(-0.093999, 51.3627, "Croydon.pm");$map->draw("test.png");

Net-FTP-�rottle

�rottle FTP connections

my $ftp = Net::FTP::Throttle->new("ftp.example.com",MegabitsPerSecond => 2

)or die "Cannot connect: $@";

# then as with Net::FTP

String-Koremutake

Convert to/from Koremutake Memorable RandomStrings

use String::Koremutake;my $k = String::Koremutake->new;

my $s = $k->integer_to_koremutake(65535);# botretremy $i = $k->koremutake_to_integer(’koremutake’);# 10610353957

Term-ProgressBar-Simple

Edmund extended my Term-ProgressBar-Quiet:provides a simple progress meter if run interactively

use Term::ProgressBar::Simple;my @todo = ( (’x’) x 10 );my $progress = Term::ProgressBar::Quiet->new(

scalar(@todo),);

foreach my $todo (@todo) {# do something with $todo$progress++;

}$progress->message(’All done’);
