ros2 pkg create: Add --message and --service

[peci1]

Description

It would be nice if ros2 pkg create would also have --message and --service in addition to --node-name and --library-name.

Motivation

It would be great if pkg create could generate a properly configured package with messages and services.

Design / Implementation Considerations

When --message or --service is used, package type has to be ament_cmake.

Additional Information

package type has to be ament_cmake

One of the roadmap items we are considering for L-turtle is rosidl enhancements to break the dependence on cmake for message generation. Nothing committed yet, but FYI.

It would be nice if ros2 pkg create would also have --message and --service in addition to --node-name and --library-name.

This could look like: ros2 pkg create ... --message MyMsg OtherMsg --service MySrv --action MyAction

That would create:

• msg/MyMsg.msg
• msg/OtherMsg.msg
• srv/MySrv.srv
• action/MyAction.action

It would be great if pkg create could generate a properly configured package with messages and services.

Then we could update these tutorials:

2. https://docs.ros.org/en/rolling/Tutorials/Beginner-Client-Libraries/Single-Package-Define-And-Use-Interface.html

Just for clarification, do you mean to say something like a rosidl_cli or generator is being considered to break cmake dependencies?

Hey everyone,
I have taken a stab at solving this issue by introducing a --message field to ros2 pkg create in #1202.
