Template filters¶

Besides Jinja2 builtin filters, custom user-defined filter functions can be loaded using the config entry filter_file:

Example:

The config file:

config:
  filter_file:
  - /tmp/myfilter_file.py

The python filter under /tmp/myfilter_file.py:

def myfilter(arg1):
  return str(int(arg1) - 10)

The dotfile content:

{{@@ "13" | myfilter() @@}}

For more information on how to create filters, see the Jinja2 official docs.
