provide a way to synchronously parse an error

[elesueur]

I have been using the 0.6 versions of stacktrace-js, but I was getting a warning from chrome about synchronous requests from the main thread being deprecated, so I am investigating updating to the new version.

The case I have is I want to augment a logging module to prefix the file:line:column to each log message, but because of the asynchronous nature of the interface that stacktrace-js exposes, it doesn't seem possible to do it.

I have hacked at the fromError method to remove the asynchronous interface and just return the stack frame array, and it seems to work, but I am no longer calling into the GPS module. I guess it's the GPS module that needs to download the source map.

It would be good to also provide an synchronous interface, e.g.:

70 /**
71 * Given an error object, parse it synchronously without source mapping.
72 * @param error Error object
73 * @param opts Object for options
74 * @return Array[StackFrame]
75 */
76 getStackFrames: function StackTrack$$getStackFrames(error, opts) {
77 opts = _merge(_options, opts);
78
79 var stackframes = ErrorStackParser.parse(error);
80
81 if (typeof opts.filter === 'function') {
82 stackframes = stackframes.filter(opts.filter);
83 }
84
85 return stackframes;
86 },

Sorry, I meant to file this issue against stacktrace-js, not stacktrace-gps.

@elesueur If all you want to do is parse an Error (and not enhance it with source maps, etc.) then error-stack-parser is for you. It does exactly what you describe!

Please let us know if I misunderstood your request or error-stack-parser doesn't do everything you want.
