A task for compiling ROS message types into Elixir structs.

Add the messages that you want to your mix.exs:

# mix.exs
...
def project do
  [
    msg: messages()
    ...
  ]
end

def messages do
  [
    "sensor_msgs/Image",
    {:pattern, "std_msgs"}
  ]
end

Running mix genmsg after this will produce structs for SensorMsgs.Image and StdMsgs.* under lib/generated_msgs/. It is recommended to put this directory in your .gitignore.

Giving the {:pattern, String.t()} directive will tell the compiler to create structs for all available message types that contain the given pattern.
