bridge

  • Bridge provides a C++11 subset playground even if no C++11 is present.
  • Bridge provides a few macro utils, aimed to cross-development.
  • Bridge pollutes macros on purpose. Sorry but I think this is convenient.
  • Bridge is cross-platform.
  • Bridge is header-only.
  • Bridge is zlib/libpng licensed.

std:: library wrapper

  • on C++11 platforms, bridge includes a few c++11 headers only.
  • on C++03 platforms, bridge fallbacks to a few boost libraries.
  • additionally 128-bit headers are included if possible.
  • bridge recreates a safe std:: playground that wraps all std::mutex variants, std::thread, std::function, std::bind, std::placeholders and std::(u)int\*_t types (for now).
{
  std::thread( classA() ).detach();

  std::mutex m;
  std::scope_lock guard(m);

  std::function<int(int,const char**)> fn( main );

  using namespace std::placeholders;
  return std::bind( fn, _1 );
}

Bridge macros

  • Bridge macros can contain multiline text and/or code
  • These macros can be located inside functions, global namespaces, and #if directives.

static $tls(bool) acquired = false;

Platform macros

  • $windows(...), $welse(...)
  • $linux(...), $lelse(...)
  • $apple(...), $aelse(...)
  • $ios(...), $ielse(...)
  • $osx(...), $oelse(...)
  • $undefined_os(...)
int dir() {
  $windows( return system("dir") );
  $welse( return system("ls -la") );
  return 0;
}

Compiler macros

  • $msvc(...), $melse(...)
  • $gnuc(...), $gelse(...)
  • $clang(...), $celse(...)
  • $undefined_compiler(...)
int main() {
  $msvc( __asm int 3 );
}

Exception macros

  • $throw(...), $telse(...)
int main() {
  $throw(
    try {
      setup();
      game();
    } catch(...) {
      /*...*/
    }
  );
  $telse(
    setup();
    game();
  );
}

  // disable logging
  $release({
    fclose(stderr);
    fclose(stdout)
  });
}

Warning macros

  • $warning(...)
  • $todo(...)
$warning("line printed in compile time");
$todo("cook food");
int main()
{}

Directive macros

  • $on(...)
  • $is(...)
  • $has(...)
#if $on($windows))
#  include <windows.h>
#else
#  include <unistd.h>
#endif

int main()
  if( $on($linux) && $on($release) ) {
    print("linux-release");
  }
}

Stringify macro

  • $quote(...)
std::string text = $quote(
this is a multine
string
);

Un/Comment macros

  • $comment(...), $uncomment(...)

 $comment(
  print("this code...");
  print("...is never compiled");
 );
}

C++03/11 macros
