Is there any plan to port this project to ROS2?

@kralf
Maybe some guides where to start for those who dare to try? :)

I would also be very interested for a ROS2 Foxy version. I'll like to try but a guide to which files are specific to ROS and which are not would be nice.
Also, one big issue will definitely be the issue of QoS compatibility between publishers and subscribers

Any update on this? I am also interested on running multiplot on ROS2. Did anyone found another solution or a guideline to adapt this solution?

Hello everyone,

we do not have plans at the moment to port this package to ROS2. If anyone wants to contribute, I am happy to create a ros2 branch!

[GuihVicentini]

Hi @remod I kind of have interest on this, but I am clueless on what are exactly the ROS1 dependencies on this project. Could you give me a starting point?

[remod]

Hi @GuihVicentini

I am unsure whether I understood the question correctly - does the migration guide to ROS2 help?

Hi @remod,

First overall, @kralf, @remod and others, kudos for the fantastic project!

It would be super to have this plugin in ROS2. Were there some steps taken in this direction?
If not, I can take care of it. I will be doing it in my free time, so it probably will take a while to do this porting, but I hope not longer than to end of this year :P

Hi @abrzozowski

That would be great, thank you! We're still using ROS1 and therefore cannot assist with the implementation, but we can help with the review! How would you like to proceed? Create a ros2 branch?

[abrzozowski]

Hi @remod,

Great! I will create a fork of this repo, and I will be porting on this fork. When everything works, I will create a PR to this main repo (https://github.com/ANYbotics/rqt_multiplot_plugin). Then we'll do the review. Is it a good plan?

I think that creating a ros2 branch in the main repo is an excellent idea because it can show others that there is someone who works on porting.

[remod]

Yes that sounds great!

One input from my side: ROS2 brings along some code formatting tools. To ensure that potential bugfixes are compatible with both versions of rqt_multiplot_plugin, ROS1 and ROS2, I suggest that we do not reformat code on the ROS2 branch - is this fine for you?

[abrzozowski]

Ok, I thought about it. I will be changing as minimally as possible. This approach should help with future merging ros1-releases into ros2 as well

[abrzozowski]

I've taken a look at what is a work scope. There is one more package to port except this, a https://github.com/ANYbotics/variant. The rqt_multiplot_plugin is dependent on the variant

[remod]

Yes exactly. In case you are not aware, the variant package does some ROS message definition parsing. Porting it to ROS2 might involve a bit more work than usually when porting a node.

Is there any ongoing activity on this topic?

[remod]

Hi @nlamprian !

I personally am not aware of any activity.
