Class BeanShell

java.lang.Object
  org.gjt.sp.jedit.BeanShell

public class BeanShell
extends java.lang.Object

BeanShell is jEdit's extension language.

When run from jEdit, BeanShell code has access to the following predefined variables:

view - the currently active View.
editPane - the currently active EditPane.
textArea - the edit pane's org.gjt.sp.jedit.textarea.JEditTextArea.
buffer - the edit pane's Buffer.
wm - the view's org.gjt.sp.jedit.gui.DockableWindowManager.
scriptPath - the path name of the currently executing BeanShell script.
