| In data compression, BCJ, short for Branch-Call-Jump, refers to a technique that improves the compression of | |
| machine code of executable binaries by replacing relative branch addresses with absolute ones. | |
| This allows a LZMA compressor to identify duplicate targets and archive higher compression rate. | |
| BCJ is used in 7-zip compression utility as default filter for executable binaries. | |
| pybcj is a python bindings with BCJ implementation by C language. | |
| The C codes are derived from p7zip, portable 7-zip implementation. | |
| pybcj support Intel/Amd x86/x86_64, Arm/Arm64, ArmThumb, Sparc, PPC, and IA64. | |
| Development status | |
| ================== | |
| A development status is considered as ``Beta`` state. | |
| Installation | |
| ============ | |
| As usual, you can install pybcj using python standard pip command. | |
| .. code-block:: | |
| pip install pybcj | |
| Alternatively, one can also use conda: | |
| .. code-block:: | |
| conda install -c conda-forge pybcj | |
| WARNING | |
