== Macros ==
Macros allow the insertion of system features into normal wiki pages; the only thing that makes those pages special is that they contain macros. If you edit pages like RecentChanges or SystemInfo, you'll see what that means.

For more information on the possible markup, see HelpOnEditing.

=== Search macros ===
MoinMoin now uses a new search engine, that lets your make sophisticated searches using both the interactive search box or any of the search macros. For more help, see HelpOnSearching.

<<FootNote>>

=== Writing your own macro ===
Create a python file called {{{MacroName.py}}} located in your {{{data/plugin/macro}}} directory. Ensure it has a single method called {{{execute(macro, arguments)}}}, which is the entry-point.

 * ''macro'' is an instance of class Macro, and also evaluates to a string of the macroname.
 * ''arguments'' is an arbitrary argument string you can pass in with parameters to your macro.

All `Macro` instances have a `request` member through which you can access the form parameters and other information related to user interaction.

`execute()` should use the formatter to construct valid markup for the current target format. In most cases this is HTML, so writing a macro which returns HTML will work in most cases but fail when formats like XML or `text/plain` are requested.

For example, your wiki page has the following line on it:

{{{
<<MacroName(arg1,arg2,arg3)>>
}}}
You could write a !MacroName.py file like this:

{{{
#!python
Dependencies = []
def execute(macro, args):
    return macro.formatter.text("I got these args from a macro %s: %s" %
    (str(macro), args))
}}}
 . /!\ Add an entry into `Dependencies` if the output from your macro should not be cached. This is important if the macro output could change from one moment to another, for example if your macro searches in wiki pages which may be being edited by other users, or loads information from an external database whose contents may change. Currently the value of any entry does not matter and may be considered a short description for 'why results from this macro should not be cached', but please look at the entries used in other macros for values which may be suitable.
