Bug Description

Is it possible to implement decompressing from STDIN? Or is this not possible or has no practical value? Or is this already implemented somehow and needs more documentation (I couldn't figure it out)?

Hmmm, based on Yavor's contribution list in pbzip2.cpp version 1.1.5 it sounds like this is already implemented:

"Signalling error on stdin decompression when file doesn't start with correct bzip2 magic header"

"Handle decompression of very long bz2 streams incrementally instead of loading whole streams in memory at once"

I'll poke around and see if I can figure it out, but maybe some more documentation is called for. Thanks!

Okay, turned out it was simple and I was just mistakenly calling 1.0 on my system instead of the 1.1.5 that I had built. But documentation of this feature would still be nice. Thanks!

Perhaps we should add a statement like this:
"If no file names are given, pbzip2 compresses or decompresses from standard input to standard output. "
to the man page and to the help message.

That would be nice. I think adding an example that uses STDIN would be the most straightforward way to document.

Would also be helpful if the changelog made it more clear when this became available since my original version was 1.0 and didn't have this.
