        "description": "# SemaVer\n\nSemaVer is a simple library for Python that helps to work with versions using \n[semantic versioning notation].\n\n\n## Build status\n\n[![Build Status](https://travis-ci.org/ashep/semaver.svg?branch=master)](https://travis-ci.org/ashep/semaver)\n[![Coverage](https://codecov.io/gh/ashep/semaver/branch/master/graph/badge.svg)](https://codecov.io/gh/ashep/semaver)\n\n\n## Requirements\n\n[Python] >=3.5\n\n\n## Installation\n\n```bash\npip install semaver\n```\n\n## Usage\n\n\n### Version objects\n\nTo create version, instantiate `Version` class passing version identifier as a \nconstructor argument: \n\n```python\nfrom semaver import Version\n\nv1_0_0 = Version('1.0.0')\n```\n\nValid version identifiers can be found as [https://semver.org/] except that \ncurrently *SemaVer* does not support [pre-release]\nand [build metadata] specs.\n\nAll non-specified parts of the version identifier counted as zeroes, i. e. \n`'1' == '1.0' == '1.0.0'`.\n\n\n### Compare versions\n\nYou may compare versions using regular [Python comparison operators]:\n\n```python\nfrom semaver import Version\n\nv1_0 = Version('1.0')\nv1_0_0 = Version('1.0.0')\nv1_0_1 = Version('1.0.1')\n\nassert v1_0 == v1_0_0  # True\nassert v1_0 != v1_0_0  # False\n\nassert v1_0 < v1_0_1  # True\nassert v1_0 <= v1_0_1  # True\nassert v1_0 > v1_0_1  # False\nassert v1_0 >= v1_0_1  # False\n\n# Or using plain strings\n\nassert v1_0 == '1'  # True\nassert v1_0 == '1.0'  # True\nassert v1_0 == '1.0.0'  # True\n```\n\nAlso it is possible to compare versions against strings:\n\n```python\nfrom semaver import Version\n\nv1_0 = Version('1.0')\nv1_0_0 = Version('1.0.0')\nv1_0_1 = Version('1.0.1')\n```\n\n### Adding and subtracting versions\n\n```python\nfrom semaver import Version\n\nprint(Version('1.0.0') + Version('0.1.1'))  # '1.1.1'\n```\n\n```python\nfrom semaver import Version\n\nprint(Version('2.0.1') - Version('1.0.1'))  # '1.0.0'\n```\n\n\n### Version range objects\n\nInstance of `VersionRange` represents a version range. First argument of \nconstructor is a version range identifier. \n\n```python\nfrom semaver import VersionRange\n\nVersionRange('1.x')\n```\n\nFollowing formats are supported.\n\n- [PEP-440 version specifiers] except `~=` and `===` clauses.\n- [NPM version range syntax].\n\nFor example, each item of the following list shows equal version range \nidentifiers: \n\n- `1.x`, `1.*`, `^1`, `>=1,<2`.\n- `^1.1`, `>=1.1,<2`.\n- `1.0.x`, `1.0.*`, `~1`, `~1.0`.\n\n\n## Checking if a version is in a range\n\n```python\nfrom semaver import Version, VersionRange\n\nv1_2_3 = Version('1.2.3')\nv1_x = VersionRange('1.x')\nv2_x = VersionRange('2.x')\n\nassert v1_2_3 in v1_x  # True\nassert v1_2_3 in v2_x  # False\n\n# Or using plain strings\n\nassert '1.2.3' in v1_x  # True\nassert '1.2.3' in v2_x  # False\n```\n\n## Checking if a range is in a range\n\n```python\nfrom semaver import VersionRange\n\nv1_to_3 = VersionRange('>=1,<=3')\nv2_x = VersionRange('2.x')\n\nassert v2_x in v1_to_3  # True\nassert v1_to_3 in v2_x  # False\n\n# Or using plain strings\n\nassert '2.x' in v1_to_3  # True\nassert '>=1,<=3' in v2_x  # False\n```\n\n\n## Testing\n\n```bash\ntox\n```\n\n\n## Contributing\n\nSee the [CONTRIBUTING.md] file for details.\n\n\n## Changelog\n\nSee the [CHANGELOG.md] file for details.\n\n\n## Support\n\nIf you have any issues or enhancement proposals feel free to report them via \nproject's [Issue Tracker](https://github.com/ashep/semaver/issues). \n\n\n## Authors\n\n* [Oleksandr Shepetko](https://shepetko.com) -- initial work.\n\n\n## License\n\nThis project is licensed under the MIT License.
