Mechanism to use Macros within Templates

[Ilias Lazaridis]

I would like to provide a wiki template in order to include the
TracNav Macro (and some others) by default.

Is there any mechanism available to call macros from within templates?

I guess you already tried the various incarnations of WikiInclude
macros/plugins and the TracWikiTemplates plugin, and that didn't work?

this would not work by design.

The requirements are:

* no need to modify the wikipages
* ability to switch the extension on/off (Component)

I've implemted this manually for the AutoNav Macro.

If the component "WikiBacklinks" is enabled, the AutoNav result
becomes available on every page:

http://dev.lazaridis.com/base/browser/infra/tracx/tracx/menus.py?rev=162#L110

But this is not a generic solution (e.g. applicable to the TracNav or
other macros), because i use a copy of the macro and insert it's
output over a variable into a custom template.

So my request is essentially, how would one implement such a solution
in a generic way?

class WikiApplyMacroToAllPages(Component):

# which event to claim

# how to access/call a macro
<access-path>.MacroName.<function>(<parameters>)

I've implemented this based on a workaround, using

46 <div py:if="chrome.nav['tracnav']">
47 ${wiki_to_html('[[TracNav]]')}
48 </div>

But this functionality should be provided somehow from within trac:

as a side-question: How can I ask in the template, if one component is
enabled?

Something like:

<div py:if="tracx.menue.MyComponent.enabled">
