HA is an archiver which I released in January 1993 as version 0.98.
|
|
After that I had plans to improve speed, archive handling etc. which
|
|
would have required total rewrite of the code. For that I unfortunately
|
|
could not find time. Because there has been quite considerably interest
|
|
for internals of HA (especially for the HSC compression method) I
|
|
decided to make a source level release from my current test version
|
|
(0.999 beta) and place it under GNU General Public License. The sources
|
|
for this version are not very consistent or clean, but everything should
|
|
work.
|
|
|
|
There are several improvements which should be made before this could be
|
|
called version 1.0. Some of the most obvious of these are:
|
|
- Compression methods should be coded in assembler for PC and using more
|
|
efficient data structures for 32 bit platforms. Current version does
|
|
some things only to overcome 64kB segments of 8086.
|
|
- UNIX port has still some problems and is missing some things (for example
|
|
a grouping operator in wildcard matches).
|
|
- File handling is far from optimum.
|
|
- Archive handling is not too clever either.
|
|
- Testing should be done more thoroughly as there are many special cases
|
|
in compression routines which get used very rarely.
|
|
- Documentation of code and algorithms is totally missing.
