Subpackage Descriptions
single # Python bindings for libversion [image] [CI] [PyPI downloads] [PyPI version] [PyPI pythons] [Github commits (since latest release)] ## Purpose Python bindings for libversion, which provides **fast**, **powerful** and **correct** generic version string comparison algorithm. See [libversion] repository for more details on the algorithm. ## Performance **libversion** is 10x to 100x faster than other version comparison facilities widely used in Python world. | Facility | comps/sec | |-------------------------------------|----------:| | **libversion.version_compare2** | 3492.81K | | **libversion.version_compare** | 3219.02K | | **libversion.Version** | 374.08K | | tuple(map(int, (v.split('.')))) | 206.02K | | cmp_version.cmp_version | 189.15K | | cmp_version.VersionString | 156.42K | | distutils.version.StrictVersion | 75.00K | | version.Version | 71.39K | | distutils.version.LooseVersion | 51.38K | | pkg_resources.parse_version | 22.26K | ## Correctness **libversion** handles certain complex version cases better than other version comparison facilities. Here are some example cases where others fail: | Test case | libversion | tuple | StrictVersion | LooseVersion | parse_version | cmp_version | |-------------------------|------------|---------------|---------------|---------------|---------------|---------------| | 1.0 == 1.0.0 | ok | incorrect (<) | ok | incorrect (<) | ok | ok | | 1.2_3 == 1.2-3 | ok | fail | fail | incorrect (>) | incorrect (<) | ok | | 1.2.3 == 1.2-3 | ok | fail | fail | fail | incorrect (>) | incorrect (<) | | 1.0alpha1 == 1.0.alpha1 | ok | fail | fail | ok | ok | incorrect (>) | | 1.0rc1 < 1.0 | ok | fail | fail | incorrect (>) | ok | incorrect (>) | | 1.0 < 1.0patch1 | ok | fail | fail | ok | incorrect (>) | ok | | 1.0.2a < 1.0.2g | ok | fail | fail | ok | incorrect (>) | ok | Note 1: **fail** means that attempt to compare versions has thrown an exception, usually bacause a library cannot parse specific version string. Note 2: **version** module was not able to complete any tests as it's a strict semantic version implementation which require 3 version components. Also, it does not support Python 3 without modification. ## Python wrapper features - Provides API similar to C library, `version_compare(a, b)` function - Provides more pythonic (but slower) `Version` class with overloaded comparison operators ## Requirements - Python 3.6+ - pkg-config - [libversion] 2.7.0+ ## Example code ```python from libversion import Version, version_compare assert(version_compare("0.9", "1.1") < 0) assert(version_compare("1.0", "1.0.0") == 0) assert(version_compare("1.1", "0.9") > 0) assert(Version("0.9") < Version("1.1")) assert(Version("1.0") == Version("1.0.0")) assert(Version("1.1") > Version("0.9")) assert(Version("0.999") < Version("1.0alpha1")) assert(Version("1.0alpha1") < Version("1.0alpha2")) assert(Version("1.0alpha2") < Version("1.0beta1")) assert(Version("1.0beta1") < Version("1.0pre1")) assert(Version("1.0pre1") < Version("1.0rc1")) assert(Version("1.0rc1") < Version("1.0")) assert(Version("1.0") < Version("1.0patch1"))
