Readme for hascar-0.2.0.0
[back to package description]
What is hascar?
HASCAR is a free unzip utility for SAP's SAPCAR format.
It is implemented 100% in haskell, including the lzh decompression routine.
This is not yet in a stable state. It should successfully unpack lzh compressed files and uncompressed files.
The SAPCAR container format decoder is based on research done by Martin Gallo (https://github.com/CoreSecurity/pysap) with further investigation by Hans-Christian Esperer hc@hcesperer.org, who also did the LZH decompressor reimplementation.
What is supported:
- Reading SAPCAR archives version 2.01 only
- Unpacking files that are LZH compressed
- Unpacking files that are not compressed
TODO:
- Implement LZC
- Implement packing functionality
- Maybe implement signature checking
- Make the LZH algorithm more efficient (the author just about started to learn haskell when he embarked on implementing that algorithm :-)
Installing hascar
To compile and install, first get stack ( http://docs.haskellstack.org/en/stable/README/), then issue:
stack build && stack install
hascar will be installed to ~/.local/bin
Usage
Run hascar with the -h flag to get help. Basically, the usage should be the same as with SAP(R)'s sapcar tool.
Example run:
hc@espererh-pc ~/I/hascar λ hascar -xtvf /home/hc/test.sar
