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> * Building one of these command line debuggers requires creating language-specific instances of: * <ol> * <li>{@link com.oracle.truffle.tools.debug.engine.DebugEngine}, * noting that this instance also depends on related services provided by the language implementation,</li> * <li>{@link com.oracle.truffle.tools.debug.shell.REPLServer}, best accomplished by copying the implementation for * Truffle's demonstration language "Simple" (a.k.a. "SL").</li> * </ol> * * <strong>Disclaimer: </strong> although these command line debuggers are useful, they are * not intended, and will not be maintained as, fully functioning debuggers. They should be * considered valuable tools for the maintainers of the {@link com.oracle.truffle.tools.debug.engine.DebugEngine}, * as well as for Truffle language implementors for whom concurrent access to any kind debugging services can * be quite helpful. * <p> * <strong>Note:</strong> Both the functionality and API for this package are under active development. * <p> * @see com.oracle.truffle.api.instrument * @see com.oracle.truffle.tools.debug.engine */ package com.oracle.truffle.tools.debug.shell;
