This insertion plugin adds links to files or images found in a specific directory matching the supplied pattern. Only tested on windows.

Filefind insertion

The filefind insertion tag has the following form


Pattern The pattern should be a Unix shell-style wildcards. When the -re option is used you can use a regular expression.

Path The path can be relative to the wiki folder or an absolute path.


  • -d : Show only links to directories
  • -f : Show only links to files
  • -s : recurse subdirs
  • -re : use full regular expression

Examples List all files with index.html as last part of the name in a specific folder and subfolders:

[:filefind: "*index.html c:\doc\";-s]

List all files ending in pdf or doc in a specific folder and subfolders:

[:filefind: "(pdf|doc)$ C:\some\folder";-s;-re]

Imagefind insertion

The imagefind insertion tag has the following form



  • r##% : resize to percentage of original i.e. r50%
  • s###x### : resize to specific size i.e. s100x50


  • -s : recurse subdirs
  • -re : use full rexexp

Examples Show all jpg images ending with the number 7 in a specific folder and subfolders and resize to 20%:

[:imagefind: "7\.jpg C:\Pictures";r20%;-re;-s]

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).

    def taskStart(self, exporter, exportType):
        This is called before any call to createContent() during an
        export task.
        An export task can be a single HTML page for
        preview or a single page or a set of pages for export.
        exporter -- Exporter object calling the handler
        exportType -- string describing the export type
        Calls to createContent() will only happen after a 
        call to taskStart() and before the call to taskEnd()

    def createContent(self, exporter, exportType, insToken):
        Handle an insertion and create the appropriate content.

        exporter -- Exporter object calling the handler
        exportType -- string describing the export type
        insToken -- insertion token to create content for (see also 

        An insertion token has the following member variables:
            key: insertion key (unistring)
            value: value of an insertion (unistring)
            appendices: sequence of strings with the appendices

        Meaning and type of return value is solely defined by the type
        of the calling exporter.
        For HtmlXmlExporter a unistring is returned with the HTML code
        to insert instead of the insertion.
