Clearcode

This plugin adds the shortcode <code>[a]</code> to replace <code><a></code> html tag. Its primary function is to simplify internal linking. Now you don’t need to worry about changing the permalinks and correcting the appearance of the permalink in your posts/pages. You can only paste ID of post/page into the shortcode and the plugin will handle everything for you. When opening a post/page the shortcode renders the permalinks and titles of linked posts/pages based on the pasted IDs.
<h4>Usage</h4>
Basic: <code>[a {post_ID}]</code> Example: <code>[a 123]</code> Returns: <code><a href="{post_permalink}">{post_title}</a></code>
Custom link text: <code>[a {post_ID}]{link}[/a]</code> Example: <code>[a 123]Example Post[/a]</code> Returns: <code><a href="{post_permalink}">Example Post</a></code>
External link: <code>[a {url}]{link}[/a]</code> Example: <code>[a http://example.com]Example Link[/a]</code> Returns: <code><a href="http://example.com">Example Link</a></code>
Additional parameters: <code>[a {post_ID} {param_name}="{param_value}"]</code> Example: <code>[a 123 target="_blank"]</code> Returns: <code><a href="{post_permalink}" target="_blank">{post_title}</a></code>
