Project description
hashver 
Is a python module to derive a unique numeric value from a version string and vice versa, adhering to following constraints:
- Resultant number must be unique for all possible values of a, b, c and d
- Each of a, b, c and d needs to be below certain maximum unsigned int guided by max possible bits allotted to each version component
- We should be able to derive unique a.b.c.d back from given number
- If a.b.c.d => x and p.q.r.s => y then, a.b.c.d < p.q.r.s => x < y
Usage
After performing python -m pip install hashver, execute python code as mentioned below.
>>> from hashver import HashVer >>> hob = HashVer() >>> hob.get_num('1.0.6') 4294967302 >>> hob.get_version_str(8590000133) 2.1.5 >>> # if your version is of format a.b.c.d, each of which should be at most 2^16 >>> hob = HashVer(bits_per_component='16.16.16.16') >>> hob.get_num('9.0.100.10') 2533274796949514 >>> hob.get_version_str(2533274796949514) 9.0.100.10
Or if you have curl,
curl -skL https://raw.githubusercontent.com/ashutoshkumr/python-hashver/master/hashver/hashver.py | python - 1.0.6 8590000133 1.0.6 : 4294967302 8590000133 : 2.1.5
Modification and Testing
If any modification is done to hashver source, use following to validate changes,
# ensure various combinations of version string or number can be derived from each other python -B ${hashver-root}/hashver.py 9.0.100.10 2533274796949514 --bpc 16.16.16.16 9.0.100.10 : 2533274796949514 2533274796949514: 9.0.100.10 # or simply add them to the existing test suite in hashver/test_hashver.py and run pytest cd ${hashver-root} && pytest
