So for the last few day's I've been mucking around with mojolicious, and there is a lot I like about it, and well a lot I don't... primarily in that it allows for some rather spaghetti mess looking templating. (like PHP)
So I just wrote this silly little thing I call Slang!
It's pretty fast too... (I think)
#!/usr/bin/perl
use Modern::Perl;
use Slang qw ( mask );
use Bench;
Bench::Start();
local $_;
$_->{'mask'} = join ('', <DATA> );
$_->{'stash'} = { lang => "en",
title => { en => "Bob's Bit's Emporium" },
content => { en => "<s>greetings.<s>lang</></>" },
greetings => { en => "Welcome!" }
};
say mask($_->{'mask'},$_->{'stash'});
Bench::MileStone();
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
Bench::End();
Bench::Report();
__DATA__
<html lang="<s>lang</>">
<head><title><s>title.<s>lang</></></title></head>
<body><s>content.<s>lang</></></body>
</html>
package Slang;
use Modern::Perl;
use String::CRC32;
require Exporter;
our @ISA = qw(Exporter);
our @EXPORT_OK = qw(mask);
our $compiled_masks;
my $debug = 0;
sub mask
{
my $crc32 = crc32($_[0]);
return $compiled_masks->{$crc32} if (defined $compiled_masks->{$cr
+c32});
my $stash = $_[1];
my $mask = $_[0];
say "compiling from scratch" if $debug;
while ($mask =~ m/<s>([^<]*?)<\/>/gs)
{
my $key = $1;
if ($key =~ m@\.@s)
{
say "dot operator detected" if $debug;
my $value;
my @keys = split /\./,$key;
my $first = 1;
foreach my $new_key (@keys)
{
say $new_key if $debug;
if ($first) { $value = $stash->{$new_key}; $first
+= 0; }
else { $value = $value->{$new_key}; }
}
$mask =~ s/<s>$key<\/>/$value/gs;
}
else
{
say "edit : $key = $stash->{$key}" if $debug;
$mask =~ s/<s>$key<\/>/$stash->{$key}/gs;
}
}
$compiled_masks->{$crc32} = $mask;
return $mask;
}

}
