| 63 | + * - Opera: full stack trace with line and column numbers | |
| 64 | + * - Chrome: full stack trace with line and column numbers | |
| 65 | + * - Safari: line and column number for the top frame only; some frames | |

| 271 | + * | |
| 272 | + * Syntax: | |
| 273 | + * s = TraceKit.computeStackTrace.ofCaller([depth]) | |
| 274 | + * s = TraceKit.computeStackTrace(exception) // consider using TraceKit.report instead (see below) | |
| 275 | + * Returns: | |
| 276 | + * s.name - exception name | |
| 277 | + * s.message - exception message | |
| 278 | + * s.stack[i].url - JavaScript or HTML file URL | |
| 279 | + * s.stack[i].func - function name, or empty for anonymous functions (if guessing did not work) | |
| 280 | + * s.stack[i].args - arguments passed to the function, if known | |
| 281 | + * s.stack[i].line - line number, if known | |
| 282 | + * s.stack[i].column - column number, if known | |
| 283 | + * s.stack[i].context - an array of source code lines; the middle element corresponds to the correct line# | |
| 284 | + * | |
| 285 | + * Supports: | |
| 286 | + * - Firefox: full stack trace with line numbers and unreliable column | |
| 287 | + * number on top frame | |
| 288 | + * - Opera 10: full stack trace with line and column numbers | |
| 289 | + * - Opera 9-: full stack trace with line numbers | |
| 290 | + * - Chrome: full stack trace with line and column numbers | |
| 291 | + * - Safari: line and column number for the topmost stacktrace element | |
| 292 | + * only | |
| 293 | + * - IE: no line numbers whatsoever | |
| 294 | + * | |
| 295 | + * Tries to guess names of anonymous functions by looking for assignments | |
| 296 | + * in the source code. In IE and Safari, we have to guess source file names | |
| 297 | + * by searching for function bodies inside all page scripts. This will not | |
| 298 | + * work for scripts that are loaded cross-domain. | |
| 299 | + * Here be dragons: some function names may be guessed incorrectly, and | |
| 300 | + * duplicate functions may be mismatched. | |
| 301 | + * | |
| 302 | + * TraceKit.computeStackTrace should only be used for tracing purposes. | |
| 303 | + * Logging of unhandled exceptions should be done with TraceKit.report, | |
| 304 | + * which builds on top of TraceKit.computeStackTrace and provides better | |
| 305 | + * IE support by utilizing the window.onerror event to retrieve information | |
| 306 | + * about the top of the stack. | |
| 307 | + * | |
| 308 | + * Note: In IE and Safari, no stack trace is recorded on the Error object, | |
| 309 | + * so computeStackTrace instead walks its *own* chain of callers. | |
| 310 | + * This means that: | |
| 311 | + * * in Safari, some methods may be missing from the stack trace; | |
| 312 | + * * in IE, the topmost function in the stack trace will always be the | |
| 313 | + * caller of computeStackTrace. | |
| 314 | + * | |
| 315 | + * This is okay for tracing (because you are likely to be calling | |
| 316 | + * computeStackTrace from the function you want to be the topmost element | |
| 317 | + * of the stack trace anyway), but not okay for logging unhandled | |
| 318 | + * exceptions (because your catch block will likely be far away from the | |
| 319 | + * inner function that actually caused the exception). | |
| 320 | + * | |
| 321 | + * Tracing example: | |
| 322 | + * function trace(message) { | |
| 323 | + * var stackInfo = TraceKit.computeStackTrace.ofCaller(); | |
| 324 | + * var data = message + "\n"; | |
| 325 | + * for(var i in stackInfo.stack) { | |
| 326 | + * var item = stackInfo.stack[i]; | |
| 327 | + * data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n"; | |
| 328 | + * } | |
| 329 | + * if (window.console) | |
| 330 | + * console.info(data); | |
