Page Includes


The Page Metadata syntax is also used for including pages into other pages.

Basic Include Syntax

For instance, to include the Warning page in another page:

{{include: Warning}}

You can supply a relative or absolute page name to the include meta -- Linking resolving rules apply. For convenience, however, if the path is not absolute, Wikked will first look in the /Templates folder for a page of that name to include. If it doesn't find one, it will resolve the path as usual.

You can make Wikked look into a different folder than /Templates by changing the templates_dir option in the configuration file. See Configuration.

Templated Include

The include metadata accepts arguments. For example, the City of Oz page may have this at the top:

{{include: Warning
    |a work in progress
    |adding references

Those arguments can then be used by the included /Templates/Warning page:

WARNING! This page is {{__args[0]}}.
You can help by {{__args[1]}}.

This will make City of Oz print the following warning:

WARNING! This page is a work in progress.
You can help by adding references.

As you can see, arguments are passed as an array named __args, and this can be inserted using double curly brackets. So {{__args[0]}} inserts the first passed argument, {{__args[1]}} inserts the second, and so on.

You can also pass arguments by name:

{{include: Presentation

And use them by name in the included /Templates/Presentation template:

This page is about a {{what}} named "{{nickname}}".

In reality, when included, a page's text will be processed through Jinja2 templating so you can also use all kinds of fancy logic. For example, if you want to support a default warning message, and an optional information message, you can rewrite the /Template/Warning page like so:

WARNING! This page is {{__args[0]|default('not ready')}}.
{%if __args[1]%}You can help by {{__args[1]}}.{%endif%}

For more information about what you can do, refer to the Jinja2 templating documentation.

Included Metadata

Pages with other pages included in them inherit the meta properties of the included pages. So if /Templates/Presentation has {{category: Characters}}, then a page including it will also be in the "Characters" category.

You can tweak that behaviour:

  • Meta properties that start with __ (double underscore) will be "local" or "private" to that page, i.e. they won't be inherited by including pages.

  • Meta properties that start with + (plus sign) will only be "added" or "given" to includnig pages, i.e. the current page won't have that property, but pages including it will.
