[Pantheios-announce] [Pantheios Tips 'n' Tricks] Pantheios::Extras::Main 0.1.1 (alpha 1) released

[Matt W. <st...@gm...>]

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.
