Filters

Filters are simple methods that allow you to modify and manipulate the output of a Liquid object or variable. They can be applied to an object or variable using the pipe character | followed by the filter name and any optional parameters. Filters can be chained together to perform multiple operations on the data.

Basic Syntax

The basic syntax for using a filter is:

{{ object | filter_name: parameter1, parameter2, ... }}

Example: Using the replace filter to replace "example" with "sample" in a string

{{ "This is an example text." | replace: "example", "sample" }}

Output:

This is a sample text.

Chaining Filters

You can chain multiple filters together by adding additional pipe characters | and filter names with their parameters. The filters will be applied in the order they are written.

Example: Using the upcase filter and the replace filter together

{{ "This is another example." | upcase | replace: "EXAMPLE", "sample" }}

Output:

THIS IS ANOTHER sample.

Built-in Filters

Liquid comes with a variety of built-in filters for common tasks such as string manipulation, formatting numbers, and working with dates. Some examples of built-in filters include capitalize, truncate, round, and date.

Example: Using the truncate filter to limit a string to 10 characters

{{ "This is a very long text." | truncate: 10 }}

Output:

This is a...
