<h2><a name="inline_images"></a>Inline images</h2>

<p>You can simply deliver emails with links to images, but usually email clients would not load them without user interaction.
It is possible though to attached the images to the email and reference them in the email body with a custom HTML tag:</p>
<pre class="prettyprint">    email {
        from      =&gt; 'foo@perl.dance',
        to        =&gt; 'bar@perl.dance',
        subject   =&gt; 'Welcome to the dancefloor!',
        body      =&gt; q{&lt;p&gt;Image embedded: &lt;img src="cid:mycid"/&gt;&lt;/p&gt;},
        type      =&gt; 'html',
        attach    =&gt; [ { Id =&gt; 'mycid', Path =&gt; '/dancefloor/dcr-header-logo.png' }],
        multipart =&gt; 'related'
};</pre>

<h2><a name="providing_plain_text_part"></a>Providing plain text part</h2>

<p><a href="https://metacpan.org/pod/HTML::FormatText::WithLinks">HTML::FormatText::WithLinks</a> makes it easy to provide a plain text version
of your HTML email:</p>
<pre class="prettyprint">my $html = template $template, $tokens, { layout =&gt; 'email' };

my $f    = HTML::FormatText::WithLinks-&gt;new;

<p>The <code>colored_origin</code> refers to the part of the message that shows the package that this
message originated in, as well as the file name and line.</p>

    Console::Colored:
      colored_regex:
       - re: "customer number \d+"
         color: "bold red"</pre>

<p>This will find customer numbers according to the pattern and make them bold and red. You can supply
a regular expression pattern and a color setting.</p>

<p>Note that there is a list under the <code>colored_regex</code> key. This means you can actually have
multiple patterns. Even really simple ones that make <code>print</code> style debugging easy
and attractive.</p>

everything. However, this works on the message only, and not on the entire formatted line of log output.
(Patches welcome!)</p>

<p>This opens up a lot of possibilities, for debugging as well as for general logging during development.</p>
<h2><a name="what_else"></a>What else?</h2>

<p>There are still some feature ideas in the backlog, but it's already pretty useful. If you would
like to see additional features, please feel free to
[open an issue on github](https://github.com/simbabque/Dancer2-Logger-Console-Colored/issues).</p>
<p>And if you happen to use Mojolicious as well and need something similar, take a look at
<a href="https://metacpan.org/module/Mojo::Log::Colored">Mojo::Log::Colored</a>, which is in the early stages of development, but works quite well.</p>
