Function Details

get_yaml_for_msg(msg, prefix=`''`, time_offset=None, current_time=None, field_filter=None, flow_style_=None, fill_arrays_=False)

source code

Builds a YAML string of message.

Parameters:

msg - A object, dict or array
flow_style_ (bool) - if True, produces one line with brackets, if false uses multiple lines with indentation, if None uses both using heuristics
prefix - prefixes all lines with this string
fill_arrays_ - if True, for all flexible size arrays an element will be generated
current_time (Time) - currently not used. Only provided for API compatibility. current_time passes in the current time with respect to the message.
field_filter (fn(Message)->iter(str)) - filter the fields that are strified for Messages.

Returns:

a string

spec_to_str(msg_context, spec, buff=None, indent=`''`)

source code

Convert spec into a string representation. Helper routine for MsgSpec. :param indent: internal use only, ``str`` :param buff: internal use only, ``StringIO`` :returns: string representation of spec, ``str``

get_srv_text(type_, raw=False, rospack=None)

source code

Get .srv file for type_ as text :param type_: service type, ``str`` :param raw: if True, include comments and whitespace (default False), ``bool`` :returns: text of .srv file, ``str``

Raises:

ROSMsgException - if type_ is unknown

list_types(package, mode=`'.msg'`, rospack=None)

source code

Lists msg/srvs contained in package :param package: package name, ``str`` :param mode: MODE_MSG or MODE_SRV. Defaults to msgs, ``str`` :param rospack: an optional rospack instance to be reused, ``rospkg.RosPack`` :returns: list of msgs/srv in package, ``[str]``

rosmsg_search(rospack, mode, base_type)

source code

Iterator for all packages that contain a message matching base_type

:param base_type: message base type to match, e.g. 'String' would match std_msgs/String, ``str``

rosmsgmain(mode=`'.msg'`)

source code

Main entry point for command-line tools (rosmsg/rossrv).

rosmsg can interact with either ros messages or ros services. The mode param indicates which :param mode: MODE_MSG or MODE_SRV, ``str``
