Core Functions¶

VCheck provides several functions for quickly checking the version of a given module:

`check_raise`(mod[, hexsha, version])	Raises an error if a given Python module does not match a particular git sha1 signature or version.
`check_warn`(mod[, hexsha, version])	Warns if a given Python module does not match a particular git sha1 signature or version.
`vcheck`(mod[, hexsha, version])	Checks a given module against either a git sha1 signature or a version.

It is possible to raise an error with check_raise, a warning with check_warn, or to obtain a boolean with vcheck:

Example

Version-checking VCheck:

>>> if vcheck.vcheck(vcheck, version='0'): print('Not version 0')
Not version 0
>>> vcheck.check_warn(vcheck, version='0')  
__main__:1: UserWarning: VersionError: Repo for module vcheck is dirty (changes have been made); version not well-defined.
>>> vcheck.check_raise(vcheck, version='0')
Traceback (most recent call last):
     ...
vcheck.versionerror.VersionError: Repo for module vcheck is dirty (changes have been made); version not well-defined.
