This page describes the current Freeplane's Scripting API. For the newest development version see Scripting API (Pre-Release). The Scripting API is in some sense extended by Freeplane's utility classes and by the Libraries included in Freeplane. There is a special page that lists Changes of the Scripting API.

Entry Points

Each script is given two variables:
