InterWiki inside WikidPad

Wouldn't you like to use a proper InterWiki syntax in your WikidPad?

Means - have Shortcuts for URLs outside your WikidPad (types: http, file, etc...), based on your "interwiki map" See Also (explanations on what is interwiki and examples of usage):

All you have to do is Add a file named interWiki.py to your user_extensions.

WIKIDPAD_PLUGIN = (("InsertionByKey", 1),)

def describeInsertionKeys(ver, app):
     """
     API function for "InsertionByKey" plugins
     Returns a sequence of tuples describing the supported
     insertion keys. Each tuple has the form (insKey, exportTypes, handlerFactory)
     where insKey is the insertion key handled, exportTypes is a sequence of
     strings describing the supported export types and handlerFactory is
     a factory function (normally a class) taking the wxApp object as
     parameter and returning a handler object fulfilling the protocol
     for "insertion by key" (see EqnHandler as example).

     This plugin uses the special export type "wikidpad_language" which is
     not a real type like HTML export, but allows to return a string
     which conforms to WikidPad wiki syntax and is postprocessed before
     exporting.
     Therefore this plugin is not bound to a specific export type.

How to use:

Add in a page (example):

[:interwiki:Wikibooks;///C++_Programming/Code/Design_Patterns///]
[:interwiki:Wikipedia;///Design_pattern_(computer_science%29///]

In "Preview" you will see:

Wikibooks: C++_Programming/Code/Design_Patterns 
Wikipedia: Design_pattern_(computer_science)
