gRPC client initialization with `CLI::App::pre_callback()` #34

Open iomz opened 3 years ago

iomz commented 3 years ago

CLI11 provides CLI::App::pre_callback() which allows injecting a code after parsing and before callbacks. The gRPC client for the xArmAPI service can be initialized with this since it is required for all the subcommands in xarm-commander – otherwise, the client initializations are redundant.
