Hi ros-users,
we went into a strange behaviour of roslaunch, which we don't know, if it is
a bug or expected behaviour.
Let's consider a config file, which contains a parameter like this: r:
rad(0.5 * pi).
If I load this file via the rosparam command-line tool r gets correctly
converted to "1.5707963267948966".
But if I load this file via roslaunch rad and pi will not be converted and
the parameter r is 'rad(0.5 * pi)'.
The launch file:
<launch>
<rosparam command="load" file="/path/to/test.yaml" />
</launch>
We tested this under c- and d-turtle. Is this the expected behaviour or a
bug?
If expected, I will repost my question on answers.ros.org, otherwise I can
file a ticket, if desired.
:-) Marcus
