Liquid tags

---

• {% something %} is called a tag in Liquid.
• There are several built-in tags in Liquid: if, else, endif, for, assign etc.
• You can also define your own tags. In the next few examples we are going to do that.

• {% tagname %} just a tagname.
• {% tagname value %} tag with a single value.
• {% tagname number number %} tag with two numbers.
• {% youtube apple banana peach %} tag with one or more values.
• {% tagname key="value" %} or {% tagname key=42 %} tag with single key-value pair.
• {% youtube id="K6EvVvYnjrY" filename="some_name.mp4" %} tag with two key-value pairs. The second one optional.
• {% include file="example/code.py" %} override the built-in include tag.
• Use scalar values passed to the render function.
• Use vector passed to the render function.
• {% latest limit=5 %} tag with key-value where the value must be a u8.
• {% latest limit=3 tag="programming" %} tag with key-value (where the value is a u8) and an optional key-value pair.

• TODO:
• {% tagname value value ... %} tag with multiple values
• {% tagname key=value key=value %} tag with multiple key-value pairs
