Transforming Data with Filters

You can transform an expression by providing one or more filters in the template expression. Filters are provided using the | pipe operator.
For example, to upper case the pet’s name:
I have one {{ @pet.type }} named {{ | upper }}
Will produce the following:
I have one cat named TIGER
Some filters accept arguments. To pass arguments to a filter, include the arguments list in parentheses: filter(arg1, arg2, ...)
Popular transformation filters are:
  • title: convert text to Title Case
  • truncate: truncate the text with ellipses. For example: @description | truncate(10) to truncate text to 10 characters.
  • join: concatenate values using a separator. For example: @names | join(",")
Under the hood, PixieBrix uses the popular Nunjucks templating language, developed by the non-profit that makes the Firefox web browser!
