Interest in some code to read DMG files?
Hi,
for the Apache Flex project I have been working hard on some code to unpack DMG images as all libs I could find were GPL I implemented everything by reading the specs. I am not quite finished. The DMG part is finished, now I'm working on parsing the mac filesystem BTree ... will still take a while, but I think locating this code in the Apache Flex project doesn't seem to be the right place. After reading the Apache Commons VFS release earlier today I think this would be the best place to put it.
Is there any interest in this?
Chris

Hi,
I have to admit, that I implemented the path I needed to unpack the flash player dmg images but designed everything to be extensible. But I definitely haven't implemented all options available.
I just wanted to know if there's interest in that code, cause I thought it would rather belong to apache commons.

I think VFS would be the better fit as the code that dealt with the
underlying file system doesn't sound like it belonged into Compress. But
I've not been contributing to VFS so don't want to speak for the
component.
@Chris, have you also implemented ADC (my knowledge ends with the
wikipedia entry which says DMGs might be compressed using ADC :-). The
pure compression parts would fit into Compress very well.
Cheers

It certainly sounds like it could fit within Commons VFS, or perhaps
Commons Compress.
DMG is tricky as it's a filesystem image, which could have many types of
filesystems within it. It sounds like you have already thought about it -
what inner filesystems in DMG would this code plan to support?

Boing :-) In this case I agree with the others that VFS or Compress are the
best fit for this :-)

If we're talking about images, why not Commons Imaging? Note that it need
some work to get in a releasable state. I worked on Imaging last fall but
then got caught up by other things. This would be a good opportunity to get
some movement into that component again.

Hello Christofer,
there is no low level filesystem image or arhive file code in VFS, so I
think it would be better to add it to commons-compress. We could then
add a VFS provider on top of it for more FS abstractions.
When implementing it, it might be good to adhere to the NIO filesystem
abstraction API, as this is a possible candidate for VFS to envolve to.
(I think commons-compress does not have a abstraction API for this).
Are you planning to support writing/creating images as well?
Gruss
Bernd
