Description Dave Herman [:dherman] 2010-06-01 16:07:41 PDT
Generalize the Reflect.parse API to accept an optional JS builder function, a la:

    Reflect.parse(src, builder)

where builder is an object with callbacks the serializer calls on every sub-node to generate the result.

Implementation attached. Next I'll document the API.

Comment 2 Dave Herman [:dherman] 2010-09-17 17:13:01 PDT
BTW, this patch builds off of the patch for 594060. The builder argument is provided as an optional 'builder' property of the configuration object.

Comment 6 Dave Herman [:dherman] 2010-12-30 14:43:27 PST
The docs now pretty exhaustively detail the API for the optional builder object:

The docs have gotten pretty big, so they probably want to be split out into multiple pages. But MDC is such hell to edit I'm not sure I'm quite up to the task at the moment. At any rate, I think this is ready for review now.

No {} I think.
