[ROS2] [RQT_PUBLISHER] Traceback when closing/exiting

When using rqt_publisher under dashing, I get a traceback when closing the application on OSX. This might be related to breaking changes in dashing related to passing the context object to rcl_init().
See here: https://github.com/ros2/rcl/blob/master/rcl/include/rcl/init.h#L82 and the related PR: ros2/rcl#336

Traceback (most recent call last):

This issue might be one example for branching out to dashing-devel as described here: #10

ROS2: forward slash required in topic name

Hi,

I tried the rqt publisher plugin for ROS2 crystal and I found this bug:

• If I create a publisher on the topic /my_topic, then it's possible to start publishing messages at the specified frequency by clicking on the empty box in the topic column.

• If I create a publisher on the topic my_topic, that empty box is not displayed. However I'm still able to publish messages one by one by right clicking on the publisher and selecting Publish selected once.

From what I have seen so far ROS2 allows to use topics name without the forward slash, so also in rqt it should be possible to publish messages through it.

If on the other hand you don't want to allow users to publish messages on topics without the forward slash, you should at least prompt a warning that the specified topic name is not correct.

Malformed message_type: sequence<string>

Hello everyone,

• Ubuntu 20.04, ROS2 Galactic

I have an issue about rqt gui. When I try to publish string[] via using rqt message publisher, it returns [get_message_class]: Malformed message_type: sequence

Is there any solution? Thanks for everything.

ROS2: Add option to fill `builtin_interfaces/Time` field from actual clock

Sometimes I prefer the message published to contain actual timestamp.
In rclpy I use node.get_clock().now().to_msg() to fill a stamp field in header of stamped messages.

Maybe add option to evaluate now() or something like that?

Ros2 port: If an invalid message type is specified, rqt_publisher will cause rqt_gui will crash

[ROS2][RQT_PUBLISHER] types are not displayed correctly

There is a mismatch in the types. When choosing the type of the message, it's getting displayed without the newly introduced msg or srv middle part of it. However, when restarting, the latest added publisher has the correct type assigned.

See the following screenshot for clarity.

ROS2: Publish an array with rqt

Hi everyone, I have been using rqt to publish messages to test my applications, however I still haven't found a way to publish a message that includes an array.
In my custom message I have a variable size array declared as uint8[]. I notice in rqt that the expected type is "sequence".
I have tried different expressions, but couldn't figure out the correct one. Could someone provide an example please?

[ROS2][RQT_PLOT] malformed message type

When opening rqt_plot I see the following error messages:

[ERROR] [get_message_class]: Malformed message_type: rcl_interfaces/msg/ParameterEvent
TopicCompleter.update_topics(): could not get message class for topic type "rcl_interfaces/msg/ParameterEvent" on topic "/parameter_events"

This error occurs for every type. I believe it's related to the change of type descriptions a.k.a <pkg_name>/msg/<MessageName>

ROS2 - Windows 10 : AttributeError: module 'numpy' has no attribute 'float128'

On Rqt with Win10, trying to open rqt_publisher yields this error and doesn't work :

PluginManager._load_plugin() could not load plugin "rqt_publisher/Publisher":

To solve it, I had to remove in rqt_publisher/src/rqt_publisher/publisher.py at line 60 numpy.float128, and it seems to run smoothly without it.

try:
import numpy
_numeric_types += [
numpy.int8, numpy.int16, numpy.int32, numpy.int64,
numpy.float16, numpy.float32, numpy.float64,
]

ROS2: Changing perspectives adds duplicate topics

Creating a new perspective and changing back and forth causes topics to be duplicated.

foxy bug

I tested the foxy-devel branch and found that rqt_publisher doesn't responding to a change in a message. I think the problem is in commit where _change_publisher_expression was deleted but https://github.com/ros-visualization/rqt_publisher/blob/foxy-devel/src/rqt_publisher/publisher.py#L158 doesn't change

[ROS2] Consider branching out to `dashing-devel`

Given the latest changes in ROS2 for the dashing release, I believe it makes sense to branch out to a dashing-devel branch.

One of the changing is for example the exposure of history-depth as a QoS.

ROS2: Cannot set/publish JointState with user-specified values

Hi,
On Ubuntu 22.04 with ROS2 Humble I'm unable to publish sensor_msgs/msg/JointState with user-specified values. I suppose this might be related to #27, #28.

This is what I'm publishing:

And this is what I'm receiving (note that the std_msgs/msg/Bool seems to be working).
