[ros-users] Rospy get available services

[Ken Conley]

There's currently no high level API for this, but it's only a couple of
lines of code. The example below is cturtle. For boxturtle use
"roslib.masterapi" instead.

$ rospython rosgraph
>>> import rosgraph.masterapi
>>> m = rosgraph.masterapi.Master('/mynode')
>>> m.getSystemState()[2]
[['/rosout/set_logger_level', ['/rosout']], ['/rosout/get_loggers',
['/rosout']]]
>>> services = m.getSystemState()[2]
>>> service_names = [x[0] for x in services]
>>> service_names
['/rosout/set_logger_level', '/rosout/get_loggers']

or, more briefly:

service_names = [x[0] for x in
rosgraph.masterapi.Master('/mynode').getSystemState()[2]]
