classmethod from_stdout(value)

Parameters:

value (str) –

libvcs.sync.git.convert_pip_url(pip_url)

Convert pip-style URL to a VCSLocation.

Prefixes stub URLs like ‘user@hostname:user/repo.git’ with ‘ssh://’. That’s required because although they use SSH they sometimes doesn’t work with a ssh:// scheme (e.g. Github). But we need a scheme for parsing. Hence we remove it again afterwards and return it as a stub. The manpage for git-clone(1) refers to this as the “scp-like styntax”.

Return type:

VCSLocation

Parameters:

pip_url (str) –
