Pantheios::Extras::Main 0.1.1 (alpha 1) released

I've just released the first publicly available version - 0.1.1 (alpha 1) - of Pantheios.Extras.Main; details here.


It allows a user to replace code such as:

char const PROGRAM_NAME[] = "myprogram";

  int main(int argc, char** argv)
  {
    try
    {
      . . . // program logic

      return EXIT_SUCCESS;
    }
    catch(std::bad_alloc&)
    {
      pantheios::logputs(pantheios::alert, "out of memory");
      fprintf(stderr, "%s: out of memory\n", PROGRAM_NAME);
    }
    catch(std::exception& x)
    {
      pantheios::log_CRITICAL(x);
      fprintf(stderr, "%s: %s\n", PROGRAM_NAME, x.what());
    }
    catch(...)
    {
      pantheios::logputs(pantheios::emergency,
        "unexpected unknown failure");
      fprintf(stderr,
        "%s: unexpected unknown failure\n",
        PROGRAM_NAME);
    }

    return EXIT_FAILURE;
  }

with:

char const PROGRAM_NAME[] = "myprogram";

  int program(int argc, char** argv)
  {
    . . . // program logic

    return EXIT_SUCCESS;
  }

  int main(int argc, char** argv)
  {
    return pantheios::extras::main::invoke(argc, argv,
      program, PROGRAM_NAME);
  }

As discussed in the sixth instalment of Quality Matters, Exceptions for Practically-Unrecoverable Conditions, without an exhaustive top-level try-catch statement, program robustness cannot be averred. Pantheios.Extras.Main let's you achieve that in a single statement.
