Launch Shortcuts

org.eclipse.debug.ui.launchShortcuts

This extension point provides support for selection sensitive launching. Extensions register a shortcut which appears in the run and/or debug cascade menus to launch the workbench selection or active editor.

<!ELEMENT perspective EMPTY>

<!ATTLIST perspective

id CDATA #REQUIRED>

The perspective element has been deprecated in the 3.1 release. The top level Run/Debug/Profile cascade menus now support contextual (selection sensitive) launching, and clients should provide a contextualLaunch element instead.



<!ELEMENT contextualLaunch (contextLabel* , enablement?)>

Holds all descriptions for adding shortcuts to the selection sensitive Run/Debug/Profile cascade menus.



<!ELEMENT contextLabel EMPTY>

<!ATTLIST contextLabel

mode  (run|debug|profile)

label CDATA #REQUIRED>

Specify the label for a contextual launch mode.



<!ELEMENT enablement (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

A generic root element. The element can be used inside an extension point to define its enablement expression. The children of an enablement expression are combined using the and operator.



<!ELEMENT not (not | and | or | instanceof | test | systemTest | equals | count | with | resolve | adapt | iterate)>

This element represent a NOT operation on the result of evaluating it's sub-element expression.



<!ELEMENT and (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

This element represent an AND operation on the result of evaluating all it's sub-elements expressions.



<!ELEMENT or (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

This element represent an OR operation on the result of evaluating all it's sub-element expressions.



<!ELEMENT instanceof EMPTY>

<!ATTLIST instanceof

value CDATA #REQUIRED>

This element is used to perform an instanceof check of the object in focus. The expression returns EvaluationResult.TRUE if the object's type is a sub type of the type specified by the attribute value. Otherwise EvaluationResult.FALSE is returned.



<!ELEMENT test EMPTY>

<!ATTLIST test

property CDATA #REQUIRED

args     CDATA #IMPLIED

value    CDATA #IMPLIED>

This element is used to evaluate the property state of the object in focus. The set of testable properties can be extended using the propery tester extension point. The test expression returns EvaluationResult.NOT_LOADED if teh property tester doing the actual testing isn't loaded yet.



<!ELEMENT systemTest EMPTY>

<!ATTLIST systemTest

property CDATA #REQUIRED

value    CDATA #REQUIRED>

Tests a system property by calling the System.getProperty method and compares the result with the value specified through the value attribute.



<!ELEMENT equals EMPTY>

<!ATTLIST equals

value CDATA #REQUIRED>

This element is used to perform an equals check of the object in focus. The expression returns EvaluationResult.TRUE if the object is equal to the value provided by the attribute value. Otherwise EvaluationResult.FALSE is returned.



<!ELEMENT count EMPTY>

<!ATTLIST count

value CDATA #REQUIRED>

This element is used to test the number of elements in a collection.



<!ELEMENT with (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

<!ATTLIST with

variable CDATA #REQUIRED>

This element changes the object to be inspected for all its child element to the object referneced by the given variable. If the variable can not be resolved then the expression will throw a ExpressionException when evaluating it. The children of a with expression are combined using the and operator.



<!ELEMENT resolve (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

<!ATTLIST resolve

variable CDATA #REQUIRED

args     CDATA #IMPLIED>

This element changes the object to be inspected for all its child element to the object referneced by the given variable. If the variable can not be resolved then the expression will throw a ExpressionException when evaluating it. The children of a with expression are combined using the and operator.



<!ELEMENT adapt (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

<!ATTLIST adapt

type CDATA #REQUIRED>

This element is used to adapt the object in focus to the type specified by the attribute type. The expression returns not loaded if either the adapter or the type referenced isn't loaded yet. It throws a ExpressionException during evaluation if the type name doesn't exist at all. The children of an adapt expression are combined using the and operator.



<!ELEMENT iterate (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>

<!ATTLIST iterate

operator (or|and) >

This element is used to iterate over a variable that is of type java.util.Collection. If the object in focus is not of type java.util.Collection then an ExpressionException will be thrown while evaluating the expression.



The following is an example of a launch shortcut extension point:

 

<extension point=

"org.eclipse.debug.ui.launchShortcuts"

>

<shortcut id=

"com.example.ExampleLaunchShortcutId"

modes=

"run,debug"

class=

"com.example.ExampleLaunchShortcutImpl"

label=

"Example Launch Shortcut"

icon=

"icons/examples.gif"

>

<perspective id=

"org.eclipse.jdt.ui.JavaPerspective"

/>

<perspective id=

"org.eclipse.debug.ui.DebugPerspective"

/>

</shortcut>

</extension>

In the above example, a launch shortcut will be shown in the run and debug cascade menus with the label "Example Launch Shortcut", in the JavaPerspective and the DebugPerspective.

Value of the attribute class must be a fully qualified name of a Java class that implements the interface org.eclipse.debug.ui.ILaunchShortcut.

Since 3.1, the debug platform registers a command handler for each launch shortcut and its applicable modes to allow clients to define key-bindings for a launch shortcut. The command id for a handler is generated as the launch shortcut id attribute, followed by a dot and the applicable launch mode. For example, the command id for the above launch shortcut example would be com.example.ExampleLaunchShortcutId.debug for launching in debug mode. A command and key binding could be defined as follows, to bind "ALT-SHIFT-D, E" to the launch shortcut.

   

<extension point=

"org.eclipse.ui.commands"

>

<command name=

"Debug Example Launch"

description=

"Debug Example Launch"

categoryId=

"org.eclipse.debug.ui.category.run"

id=

"com.example.ExampleLaunchShortcutId.debug"

>

</command>

<keyBinding keySequence=

"M3+M2+D E"

contextId=

"org.eclipse.ui.globalScope"

commandId=

"com.example.ExampleLaunchShortcutId.debug"

keyConfigurationId=

"org.eclipse.ui.defaultAcceleratorConfiguration"

>

</keyBinding>

</extension>
