# Filters
Output markup can take filters, which modify the result of the output statement. You can invoke filters by following the output statement's main expression with:
- A pipe character (
|
) - The name of the filter
- Optionally, a colon (
:
) and a comma-separated list of additional parameters to the filter. Each additional parameter must be a valid expression, and each filter pre-defines the parameters it accepts and the order in which they must be passed.
Filters can also be chained together by adding additional filter statements (starting with another pipe character). The output of the previous filter will be the input for the next one.
Hello {{ 'tobi' | upcase }}
Hello tobi has {{ 'tobi' | size }} letters!
Hello {{ '*tobi*' | textilize | upcase }}
Hello {{ 'now' | date: "%Y %h" }}
A filter is a Ruby method that takes one or more parameters and returns a value. Parameters are passed to filters by position: the first parameter is the expression preceding the pipe character, and additional parameters can be passed using the name: arg1, arg2
