Macros

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.

Macro	Description	Example
`[[TitleSearch]]`
	create a search box on the page, which search the page titles	See FindPage
`[[FullSearch]]`
	create a search box on the page, which search the page contents	See FindPage
`[[FullSearch()]]`

`[[FullSearch(text)]]`
	print a list of pages whose content matches the search term	Search for `powered`: FrontPage HelpOnMacros WhyWikiWorks
`[[FullSearchCached(text)]]`

1 the text cannot contain any wiki markup
2 "timestamp" can be empty (current time), a number of seconds since 1970 (unix timestamp), or a W3C time specification ("2002-01-23T12:34:56"). See RFC822, sect. 5.
3 NameTemplate is formatted with time.strftime(), with the exception of %s which is replaced by the input into the edit box (which is only shown if necessary). If NameTemplate is not specified or empty, it defaults to %s.

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:

   1 Dependencies = []
   2 
   3 def execute(macro, args):
   4     return macro.formatter.text("I got these args from a macro %s: %s" %
   5     (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.
