<ul>
<li>Namespace: <code>Melk\\UrlShortenerByMelk</code>.</li>
<li>Unique prefix: all functions, options, meta keys and hooks use the <code>urlshbym_</code> prefix, following the WordPress Plugin Handbook recommendations to avoid naming collisions.</li>
<li>Options stored in the database:
<ul>
<li><code>urlshbym_enabled_post_types</code></li>
<li><code>urlshbym_enabled_taxonomies</code></li>
</ul>
</li>
<li>Meta keys:
<ul>
<li><code>_urlshbym_short_code</code> on posts</li>
<li><code>_urlshbym_short_code</code> on terms (taxonomies)</li>
</ul>
</li>
<li>Database table: <code>{$wpdb->prefix}urlshbym_short_urls</code> is created on activation to store the mapping between short codes and objects.</li>
<li>Main hook:
<ul>
<li><code>urlshbym_short_url_clicked</code> — fired whenever a short URL is accessed, receiving the short code and the internal record ID.</li>
</ul>
</li>
<li>Rewrite rules: short URLs are handled through a rewrite rule that maps patterns like <code>/abc12</code> to <code>index.php?urlshbym_short=abc12</code>.</li>
</ul>

The Shorter Links WordPress plugin overrides the default WordPress 
“shortlink” URL with one that has a custom text in it. You can also set a 
different base URL.
A custom field called “Shorter link” is created once a post is saved, 
so that you can change the shortlink to a more memorable set of 
characters.
The choice of base URL to use for the short link can be configured within 
Settings->Shorter Links.
