Mustache-like template engines for Perl

I am used to Mojo::Template. But I noticed that I keep improving the template files by substituting a lot of html by Perl code or helper functions that generate the part of the template. Below I am trying a new approach in making my templates easier to read and maintain.

So here are typical parts of the template:

% if ($author) {
<span id="author"><%= author %></span>
% }

% foreach my $author (@$authors) {
    <%= $author %><br />
% }

Maybe to someone it looks just fine, but for me there is too much logic. I don't see html anymore, it is just plain Perl. Moreover when trying to simplify a template I try to hide various calculations into the helper functions, like here:

% foreach my $meta (@{config('meta')}) {
% for my $key (keys %$meta) {
<%== "$key=\"$meta->{$key}\" " %>
% }
% }

It becomes:

<%= meta %>

And I thought that I am trying to eliminate logic from my templates anyway, why then just not try a logic-less template engine? The first example becomes:

<span id="author">{{author}}</span>

    {{author}}<br />

Looks much better to me. I don't have to worry whether I have a scalar, an array reference or a subroutine. It iterates over my data automatically doing what I meant.

Probably the most popular logic-less template engine is mustache and it is available for various languages including Perl (

And I couldn't resist from implementing one more version too :)
