README
What is hascar?
HASCAR is a free unzip utility for SAP's SAPCAR format. You can use it to decompress sap car files on the command line. The command line utility also supports unwrapping of transport files that are contained inside patch files. (Option -p, --depat) You can also use it as a library in your own haskell programs. So far, only the latest version of sapcar files is supported, which is 2.01.
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 with further investigation by Hans-Christian Esperer [email protected], 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
- Unpacking transport files are wrapped inside a PAT file
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 :-) => Some work on this has been done; more is required.
- Implement CRC checking
Installing hascar
nixos
Users of nixos can simply install hascar by issuing "nix-env -iaP haskellPackages.hascar". Or if you only need it temporarily, open a nix-shell like this: "nix-shell -p haskellPackages.hascar"
FreeBSD/GNU_Linux/OS X/Windows
To compile and install, first get stack, then issue:
stack build && stack install
hascar will be installed to ~/.local/bin . You should set your PATH variable to point to this directory.
Verifying signatures and encrypted archives
Since both use a proprietary crypto API, this is currently not supported.
Usage
Run hascar with the -h flag to get help. The basic usage should be the same as with SAP(R)'s sapcar tool. It should be noted that the used command line parser is a bit stricter than what you might be used to.
Extracting transport files from PAT files
SAR files can contain transport files that are wrapped inside PAT (patch) files. Since hascar 0.2.2.0 the option -p is offered, that will try to automatically detect PAT files. If such a file is detected and the -p flag is set, the transport file contained in the PAT file is extracted.
