2021-05-20 07:32:30 -0500 | marked best answer | generating versioned rosinstall file from currnt workspace Hi Is there any tool that is able to dump rosinstall with version tag from current workspace or .rosinstall file? For example, I have following .rosinstall for my application, http://code.google.com/p/rtm-ros-robotics/source/browse/trunk/agentsystem_ros_tutorials/rtm-ros-robotics.rosinstall for developers to work against the trunk repositories. Then, Jenkins/Hudson server check the build status and add the latest tag. I would be very happy if I can freeze this set as a .rosinstall file with version tag in all repositories so that I can commit the file to as a stable.rosinstall file and users always be able to setup with stable set of repository versions. |
2021-04-08 02:57:33 -0500 | marked best answer | how to pass a string argument that contains white space? I have a program that takes string as an argument, such as $ ./say "hello world" and would like to invoke this program from roslaunch. Here is an example of the launch file: < launch> < node name="say" pkg="say" type="say" args='\"hello world\"' /> < /launch> When I check the command line argument with $ roslaunch say.launch --args /say the output is PYTHONPATH=/opt/ros/diamondback/ros/core/roslib/src /home/k-okada/ros/diamondback/say/say "hello world" __name:=say and this is ok to me. but when I try to start this program from launch file by $ roslaunch say.launch the argument corrupts. It seems that the roslaunch divide string arugment into each words as written in the log file [roslaunch][INFO] 2011-07-01 13:35:10,808: process[hoge-1]: args[[u'/home/k-okad a/ros/diamondback/say/say', '"hello', 'world"', u'__name:= say']] Changing the launch file to < launch> < node name="say" pkg="say" type="say" args='\"hello\ world\"' /> < /launch> worked, but if there are other solution, I would like to know that. |
