- * Syntax:

- * Returns:
- * s.name - exception name
- * s.message - exception message
- * s.stack[i].url - JavaScript or HTML file URL
- * s.stack[i].func - function name, or empty for anonymous functions (if guessing did not work)
- * s.stack[i].args - arguments passed to the function, if known
- * s.stack[i].line - line number, if known
- * s.stack[i].column - column number, if known
- * s.stack[i].context - an array of source code lines; the middle element corresponds to the correct line#
- *
- * Supports:
- * - Firefox: full stack trace with line numbers and unreliable column
- * number on top frame
- * - Opera 10: full stack trace with line and column numbers
- * - Opera 9-: full stack trace with line numbers
- * - Chrome: full stack trace with line and column numbers
- * - Safari: line and column number for the topmost stacktrace element
- * only
- * - IE: no line numbers whatsoever
- *
- * Tries to guess names of anonymous functions by looking for assignments
- * in the source code. In IE and Safari, we have to guess source file names
- * by searching for function bodies inside all page scripts. This will not
- * work for scripts that are loaded cross-domain.
- * Here be dragons: some function names may be guessed incorrectly, and
- * duplicate functions may be mismatched.
- *
- * TraceKit.computeStackTrace should only be used for tracing purposes.
- * Logging of unhandled exceptions should be done with TraceKit.report,
- * which builds on top of TraceKit.computeStackTrace and provides better
- * IE support by utilizing the window.onerror event to retrieve information
- * about the top of the stack.
- *
- * Note: In IE and Safari, no stack trace is recorded on the Error object,
- * so computeStackTrace instead walks its *own* chain of callers.
- * This means that:
- * * in Safari, some methods may be missing from the stack trace;
- * * in IE, the topmost function in the stack trace will always be the
- * caller of computeStackTrace.
- *
- * This is okay for tracing (because you are likely to be calling
- * computeStackTrace from the function you want to be the topmost element
- * of the stack trace anyway), but not okay for logging unhandled
- * exceptions (because your catch block will likely be far away from the
- * inner function that actually caused the exception).
- *
- * Tracing example:
- * function trace(message) {
- * var stackInfo = TraceKit.computeStackTrace.ofCaller();
- * var data = message + "\n";
- * for(var i in stackInfo.stack) {
- * var item = stackInfo.stack[i];
- * data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n";
- * }
- * if (window.console)
- * console.info(data);
- * else
- * alert(data);
