Some online documentation for the Instrumentation Framework is available * online: * <quote> * <a href="https://wiki.openjdk.java.net/display/Graal/Instrumentation+API">https://wiki.openjdk.java.net/display/Graal/Instrumentation+API</a> * </quote> * <p> * Debugging services for a Truffle-implemented language are provided by creating an instance * of {@link com.oracle.truffle.tools.debug.engine.DebugEngine} specialized for a specific language. The DebugEngine can: * <ul> * <li>Load and run sources in the language</li> * <li>Set breakpoints possibly with conditions and other attributes, on source lines</li> * <li>Navigate by Continue, StepIn, StepOver, or StepOut</li> * <li>Examine the execution stack</li> * <li>Examine the contents of a stack frame</li> * <li>Evaluate a code fragment in the context of a stack frame</li> * </ul> * <p> * Specialization of the DebugEngine for a Truffle-implemented language takes several forms: * <ol> * <li>A specification from the language implementor that adds Instrumentation "tags" to the nodes * that a debugger should know about, for example Statements, Calls, and Throws</li> * <li>Methods to run programs/scripts generally, and more specifically run text fragments in the context of * a particular frame/Node in a halted Truffle execution</li> * <li>Utility methods, such as providing textual displays of Objects that represent values in the language</li> * </ol> * <p> * <strong>Note:</strong> Both the functionality and API for this package are under active development. * <p> * @see com.oracle.truffle.api.instrument */ package com.oracle.truffle.tools.debug.engine;
