0. Add this app "macros" to your INSTALLED_APPS

1. In your template load the library:

   {% load macros %}

2. Define a new macro called 'my_macro' that takes args and/or kwargs All will be optional:

   {% macro my_macro arg1 arg2 baz="Default baz" %}
       {% firstof arg1 "default_arg1" %}
       {% if arg2 %}{{ arg2 }}{% else %}default_arg2{% endif %}
       {{ baz }}
   {% endmacro %}

3. Use the macro with string parameters or context variables:

   {% usemacro my_macro "foo" "bar" baz="KW" %}
   <br>
   {% usemacro my_macro num_pages "bar" %}
   <br>
   {% setmacro my_macro %} {{ my_macro }}

Renders like:

foo bar KW
77 bar Default baz
default_arg1 default_arg2 Default baz

4. Alternatively save your macros in a separate file, e.g. "mymacro.html" and load it to the current template with:

   {% loadmacros "mymacros.html" %}

   Then use these loaded macros in as described above.

Bear in mind that defined and loaded macros are local to each template file and are not inherited through {% extends ... %} tags.
