Description

This PR aims to solve the compilation error we get when messages have at least one field of type bool[].

This has been discussed in other places, like in these issues here: #445, #393, #391

Also, there has been a PR which proposes a different solution to the same problem: #411

However, I think the solution adopted in this PR here (#446) is superior:

  • it's a pure C++ solution (it does not touch the EmPy stuff)
  • it avoids creating new methods with similar names (instead it adds overloads for specific cases using enable_if_t)

Tests

The following video shows the bi-directional bridge of messages using vectors of bools based on my version of ros1_bridge:
