The Power of Liquid

After finding a way to edit my code blocks appearance. I ran into another issue. Currently the only solution I have to fix the issue, is to run javascript code on each of the code blocks. This is quite bothersome. However, I found a way to neatly integrate the code block design in compilation by using the language liquid.

So what is liquid?

From their main page:

Liquid is an open-source, Ruby-based template language created by Shopify. It is the backbone of Shopify themes and is used to load dynamic content on storefronts.

Liquid allows me to make lists in my markdown files which I can then itterate using a for each loop in liquid. For example, for my previous post my list was.

code:
- type: file
  file: Yaml
  count: 0

- type: ruby
  count: 1

- type: html
  count: 2 

- type: javascript
  count: 3

- type: html
  count: 4 

- type: css
  count: 5

Here there are 6 elements in code where each element begins with -.The type tag specifies what language I am using. The type file is a dummy tag in which the actual name is included in file. The count tag labels the code blocks starting with 0 from the top.

With this list I can itterate through them using liquid.

{% for codetag in page.code %}

{% if codetag.type == 'bash' %}

<script type="text/javascript">
$( document ).ready(function() {
     
       $("pre").addClass("terminal");
	   
		 $("<span>",{
	       rel:'  Bash'
		   }).appendTo("pre:eq({{codetag.count}})");

});	

</script>
{% endif %}

...

{% endfor %}

Where codetag loops through each item in page.code. Now, I only need to mention the type on the top of my markdown file and liquid allows me to generated the top bar of my code blocks with the proper label and icons.
