Hello all,
I would like to announce immediate availability of a new program:
SAMflate
- an implementation of the inflate decompression algorithm from
RFC1951, as used by gzip and other compatible utilities. In other
words, it's like gunzip for the Sam.
Note that I have not implemented the compression side - instead you
use the standard gzip utility on your Mac/PC/Unix computer to compress
a file, and SAMflate running on the Sam will decode it for you.
You can download it here:
http://www.worldofsam.org/freelinking/SAMflate
Source code is also available[1], for anyone who wants to incorporate
it into other programs:
http://sourceforge.net/projects/samflate/
[1] At least it will be, as soon as sourceforge admins get around to
approving the project
(requires pyz80 for assembly, I took a few shortcuts when writing it...)
Please have a go, and do let me know if you find it useful or if you
have any trouble with it!
I'd be especially interested if you have a file it can't decode (there
may be bugs in the handling of Block Types 0 and 1 - the code isn't
really tested because I couldn't persuade gzip to make that sort of
file to try it with! Block Type 2 is the most efficient, and gzip
seems to use it for all compression levels 1 to 9, so it's unlikely
that anyone will see that problem...)
Cheers,
Andrew
