datalad.cmdline.helpers.fail_with_short_help(parser=None, msg=None, known=None, provided=None, hint=None, exit_code=1, what='command', out=None)

datalad.cmdline.helpers.get_commands_from_groups(groups)

Get a dictionary of command: interface_spec

datalad.cmdline.helpers.get_repo_instance(path='.', class_=None)

Returns an instance of appropriate datalad repository for path. Check whether a certain path is inside a known type of repository and returns an instance representing it. May also check for a certain type instead of detecting the type of repository.

Parameters:

• path (str) – path to check; default: current working directory
• class (class) – if given, check whether path is inside a repository, that can be represented as an instance of the passed class.

Raises:

RuntimeError, in case cwd is not inside a known repository.

datalad.cmdline.helpers.parser_add_common_options(parser, version=None)

datalad.cmdline.helpers.parser_add_version_opt(parser, mod_name, include_name=False, delay=False)

Setup –version option

Parameters:

• parser –
• mod_name (str, optional) –
• include_name (bool, optional) –
• delay (bool, optional) – If set to True, no action is taken immediately, and rather we assign the function which would print the version. Necessary for early pre-parsing of the cmdline

datalad.cmdline.helpers.strip_arg_from_argv(args, value, opt_names)

Strip an originally listed option (with its value) from the list cmdline args
