pooch.check_version

pooch.check_version(version, fallback='master')

Check that a version string is PEP440 compliant and there are no unreleased changes.

For example, version = "0.1" will be returned as is but version = "0.1+10.8dl8dh9" will return the fallback. This is the convention used by versioneer to mark that this version is 10 commits ahead of the last release.

Parameters:

version : str

A version string.

fallback : str

What to return if the version string has unreleased changes.

Returns:

version : str

If version is PEP440 compliant and there are unreleased changes, then return version. Otherwise, return fallback.

Raises:

InvalidVersion

If version is not PEP440 compliant.

Examples

>>> check_version("0.1")
'0.1'
>>> check_version("0.1a10")
'0.1a10'
>>> check_version("0.1+111.9hdg36")
'master'
>>> check_version("0.1+111.9hdg36", fallback="dev")
'dev'
