// A decoder for Mac Bin Hex 4.0.
|
|
|
|
// This decoder is currently only intended to be used on NON-Mac platforms. It isn't hooked up to
|
|
// code which would actually save the file to disk. As a result, we can't leverage the resource fork.
|
|
// This makes this decoder most unhelpful for the Mac. Our assumption is that if you save a bin hex file
|
|
// on the mac and try to open it, stuffit or some other tool is already going to be on the Mac which knows how
|
|
// to handle bin hex. On windows and unix, that's not the case. We need client code to strip out the data fork.
|
|
// So this decoder currently just strips out the data fork.
|
|
|
|
// Note: it's possible that we can eventually turn this decoder into both a decoder and into a file stream (much
|
|
// like the apple double decoder) so on the Mac, if we are saving to disk, we can invoke the decoder as a file stream
|
|
// and it will process the resource fork and do the right magic.
