Hi,
I create a custom message for an action in a package named: my_action_act
I built and used a custom message well
I also see the message in: rosmsg list | grep my_action_act
But when I use: rosmsg show my_act… Then I use tab to complete the message. It does not work.
I see in “rosmsg show” does not list my package as action_lib, move_base_msgs.
Why? And how can I fix it. Thanks
If you want to use auto-complete, you must press tab twice in quick succession (TAB-TAB).
Also, before doing that, ensure that you have run source ~/catkin_ws/devel/setup.bash on that terminal.
I press Tab several times but it does not work
I have already run source ~/catkin_ws/devel/setup.bash on that terminal
I can list all messages of an action but can not auto-complete when using rosmsg show
I use rosmsg package <my_msg_action_pkg>, it also can not list my message. But move_base_msgs works
In rqt, other action, topic can see the message but my_action. @@
As you can see, I type:
rosmsg show [tab] [tab] …
it will list all packages and it does not have my_action_package
But I type rosmsg list | grep <my_action>, it still lists my messages normally
I do not understand this part. Could you please elaborate?
You need to press TAB twice very fast (quick succession). Is that what you did? If you just press it the usual way, it might not work.
Also, it helps to start typing one of two characters of your action message before pressing TAB-TAB.
Okay, if the only problem is with auto-completion, it is not a big deal. Are you able to use the message successfully:
If you need further help, please show the output of:
I will explain again, please help.
I build my action message (CountAction) in a package (my_action_act) → catkin_make → source … : Done
I type: rosmsg list | grep Count
Terminal shows all my action messages
I type: rosmsg show my_act [tab] [tab]… but it does not suggest or complete my message
I try: rosmsg show move_base [tab] [tab] … it works very well. It can suggest and complete the messages. It means I know how to use [tab] [tab] to complete message
=> My question is why ROS does not suggest and complete my action message. But It can suggest and complete move_base action message
=> Why is it? ^^
=> So I think after I build my_action_act package to build message, it does not add my package into result of (rosmsg show [tab] [tab]) so it can not suggest and complete my command. But why?
Could you check them for me? Thanks
Code block example; place between two triple backticks
# This is an example of a code block
It looks like the ROS system has not fully recognised your package. Perhaps something is missing. Try the following:
# recompile the workspace
cd ~/catkin_ws
rm -rf build/ devel/
catkin_make
source devel/setup.bash
rospack profile
Then, in the same terminal, try to auto-complete your message.
Please paste all output from the commands above here, in a code block (not as screenshot). I made an example of a code block in your last post.
I followed your guide and it does not work. Please check

Thank you for providing the detailed output.
Checking further, it seems this is a general problem affecting custom action messages, specifically for rosmsg show; it works when the action server is running and you do rostopic pub /action_topic. It also works for inbuilt action messages.
Perhaps something is missing in the instructions for creating custom action messages, or this is an internal bug in ROS. We’ll find out and let you know.
In the meantime, please continue with other things.
ok. Please help me soon
Yes NguyenDuyDuc, you are right.
We are looking into this issue because it is something that happens to some people and some other’s not. I’ll keep you updated
