BeanShell

public class BeanShell (Code)

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 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.

Method Detail

_eval
public static Object _eval(View view, NameSpace namespace, String command) throws Exception(Code)
	Evaluates the specified BeanShell expression. Unlike `eval()`, this method passes any exceptions to the caller. Parameters: view - The view. Within the script, references to`buffer`, `textArea` and `editPane`are determined with reference to this parameter. Parameters: namespace - The namespace Parameters: command - The expression exception: Exception - instances are thrown when various BeanShellerrors occur since: jEdit 3.2pre7

_runScript

public static void _runScript(View view, String path, Reader in, boolean ownNamespace) throws Exception(Code)

Runs a BeanShell script. Errors are passed to the caller.

If the in parameter is non-null, the script is read from that stream; otherwise it is read from the file identified by path.

The scriptPath BeanShell variable is set to the path name of the script.
Parameters:
  view - The view. Within the script, references tobuffer, textArea and editPaneare determined with reference to this parameter.
Parameters:
  path - The script file's VFS path.
Parameters:
  in - The reader to read the script from, or null.
Parameters:
  ownNamespace - If set to false, methods andvariables defined in the script will be available to all futureuses of BeanShell; if set to true, they will be lost assoon as the script finishes executing. jEdit uses a value offalse when running startup scripts, and a value oftrue when running all other macros.
exception:
  Exception - instances are thrown when various BeanShell errorsoccur
since:
   jEdit 4.0pre7

_runScript

public static void _runScript(View view, String path, Reader in, NameSpace namespace) throws Exception(Code)

Runs a BeanShell script. Errors are passed to the caller.

If the in parameter is non-null, the script is read from that stream; otherwise it is read from the file identified by path.

cacheBlock
public static BshMethod cacheBlock(String id, String code, boolean namespace) throws Exception(Code)
	Caches a block of code, returning a handle that can be passed to runCachedBlock(). Parameters: id - An identifier. If null, a unique identifier is generated Parameters: code - The code Parameters: namespace - If true, the namespace will be set exception: Exception - instances are thrown when various BeanShell errorsoccur since: jEdit 4.1pre1

eval
public static Object eval(View view, NameSpace namespace, String command)(Code)
	Evaluates the specified BeanShell expression. Errors are reported in a dialog box. Parameters: view - The view. Within the script, references to`buffer`, `textArea` and `editPane`are determined with reference to this parameter. Parameters: namespace - The namespace Parameters: command - The expression since: jEdit 4.0pre8

runCachedBlock
public static Object runCachedBlock(BshMethod method, View view, NameSpace namespace) throws Exception(Code)
	Runs a cached block of code in the specified namespace. Faster than evaluating the block each time. Parameters: method - The method instance returned by cacheBlock() Parameters: view - The view Parameters: namespace - The namespace to run the code in exception: Exception - instances are thrown when various BeanShellerrors occur since: jEdit 4.1pre1

runScript

public static void runScript(View view, String path, Reader in, boolean ownNamespace)(Code)

Runs a BeanShell script. Errors are shown in a dialog box.
