HOW TO USE INKY AND CREATE A FANTASTIC HTML EMAIL WITH IT
See https://github.com/zurb/inky for an overview of the tags that Inky introduces.
You'll likely want to use the CSS from https://github.com/zurb/foundation-emails in order to style your HTML e-mails "properly" for use with Inky.
You'll want to use the HTML "wrapper template" from https://github.com/zurb/foundation-emails-template/blob/master/src/layouts/default.html.
You might want to convert that HTML into the templating system you are going to be using, such as Template or Text::Xslate.
For example, in Template you'll want to create a wrapper.tt containing the above file's contents, and ensuring you have:
...
<center>
[% content %]
</center>
...You'll then be able to use the never-changing wrapper template to create beautiful HTML emails, creating a your_mailing_list.tt which contains something like:
[%-
SET override_css = '
// any override to be placed _after_ the Foundation for Emails CSS
';
WRAPPER "path/to/wrapper.tt"
-%]
Your email contents go here
[% END %]To style them "properly", you'll want to clone the repository at: https://github.com/zurb/foundation-emails, and make changes to the various source scss files to fit your "brand", assuming the defaults aren't to your liking.
Once done, you'll have to generate the CSS, using something like:
sass -t compact --sourcemap=none --no-cache foundation.scss > foundation.cssIf you want to include the foundation CSS and a newsletter-specific overriding CSS, you will want to modify the wrapper.tt to contain, near the body tag:
<body>
[%~# CSS::Inliner REQUIRES type = "text/css" ~%]
<style type="text/css">
[% foundation_css %]
[% override_css %]
</style>
....The style must go in the body as otherwise some mailers will wail to "use" it.
If you need to support Gmail and other mail readers which do not allow inline styles, you'll likely have no option but to use CSS::Inliner, which - with the above style addition to the wrapper.tt template, will allow you to seamlessly inline your styles in the HTML email.
It's entirely up to you to also use HTML::Packer to ensure any useless whitespace and comments are trimmed from the resulting email.
To sum up, and assuming you'll be using Template, HTML::Packer and CSS::Inliner, here's a rough program to send a beautiful HTML email with Inky and Foundation for Emails:
use 5.010_001;
use strict;
use warnings;
use Inky;
use Template;
use HTML::Packer;
use CSS::Packer;
use CSS::Inliner;
use Path::Tiny;
use Carp qw<croak>;
# Create TT object, ensure the foundation for emails CSS is in the stash
my $TT = Template->new(
# any TT options go here
);
my $stash = {
foundation_css => path('./foundation.css')->slurp_utf8,
# your other data goes here
};
my $html = '';
$TT->process('your_mailing_list.tt', $stash, \$html)
or croak $TT->error;
# At this point $html contains the full "inky" templated email.
my $INKY = Inky->new;
my $PACKER = HTML::Packer->init;
my $parsed = $INKY->release_the_kraken($html);
my $inliner = CSS::Inliner->new({ leave_style => 1, relaxed => 1 });
$inliner->read({ html => $parsed });
my $inlined = $inliner->inlinify;
my $minified = $PACKER->minify( \$inlined, {
remove_comments => 1,
remove_newlines => 1,
do_stylesheet => 'minify', # needs CSS::Packer
});
say $minified;
# $minified is your beautiful HTML email, with styles inlined,
# and ready to be sent to an unsuspecting user!That's all, folks!
