Applying a filter

Filters are global, predefined functions that change the output of a variable.

Filters are used within an output and separated by the vertical bar character (|).

Input

{{ "/my/fancy/url" | append: ".html" }}

Output

/my/fancy/url.html

Multiple filters can be used on one output. They are applied from left to right.

Input

{{ "world!" | capitalize | prepend: "Hello " }}

Output

Hello World!
