This method will parse a version like 1.3.0 into a SemanticVersion. This method is responsible for accepting any version string that any older version of pbr ever created. Therefore: versions like 1.3.0a1 versions are handled, parsed into a canonical form and then output - resulting in 1.3.0.0a1. Pre pbr-semver dev versions like 0.10.1.3.g83bef74 will be parsed but output as 0.10.1.dev3.g83bef74. :raises ValueError: Never tagged versions sdisted by old pbr result in just the git hash, e.g. '1234567' which poses a substantial problem since they collide with the semver versions when all the digits are numerals. Such versions will result in a ValueError being thrown if any non-numeric digits are present. They are an exception to the general case of accepting anything we ever output, since they were never intended and would permanently mess up versions on PyPI if ever released - we're treating that as a critical bug that we ever made them and have stopped doing that.

Decrementing versions doesn't make a lot of sense - this method only exists to support rendering of pre-release versions strings into serialisations (such as rpm) with no sort-before operator.

The default behaviour is to perform a patch level increment. When incrementing a prerelease version, the patch level is not changed - the prerelease serial is changed (e.g. beta 0 -> beta 1). Incrementing non-pre-release versions will not introduce pre-release versions - except when doing a patch incremental to a pre-release version the new version will only consist of major/minor/patch. :param minor: Increment the minor version. :param major: Increment the major version. :return: A new SemanticVersion object. r' Nr )r r r r r r )r r r Znew_prerelease_typeZnew_prereleaser] r^ r_ r r r rP s6 �zSemanticVersion.incrementr: c C s� | j s | jr(|dkr(| �� �� g}d}n | �� g}| j rR|�d||| j | jf � | jr�| j sj|�|� n |�d� |�d� |�| j� d�dd� |D ��S )a1 Construct a long string version of this semver. :param pre_separator: What separator to use between components that sort before rather than after.

This translates the PEP440/semver precedence rules into RPM version sorting operators.

For documentation on version_info tuples see the Python documentation for sys.version_info. Since semver and PEP-440 represent overlapping but not subsets of versions, we have to have some heuristic / mapping rules, and have extended the releaselevel field to have alphadev, betadev and candidatedev values. When they are present the dev count is used to provide the serial. - a/b/rc take precedence. - if there is no pre-release version the dev version is used. - serial is taken from the dev/a/b/c component. - final non-dev versions never get serials.
