Is there a gcc extension for c++ short-circuiting? -


i'd overload operator&& , operator|| on custom class, , i'd overloaded operators obey short-circuiting behavior of native counterparts.

i know there no mechanism in c++ language, i'm wondering if perhaps gcc might have sort of extension make possible. know such extension cause gcc violate official c++ standard, see disclaimer on gcc documentation reads, "by default, gcc provides additional extensions c++ language on rare occasions conflict c++ standard", doesn't seem outlandish ask.

if there fundamental reason why such extension not work, in theory, know educational purposes. feels me short_circuit_inline keyword can used drop-in replacement inline have well-defined meaning , straightforward implementation, maybe wrong.

for it's worth, have macro workaround, and(x,y,...,z) short-circuited x && y && ... && z instances of custom class. desire operators cosmetic purposes.

the answer "no". gcc c++ extensions documented here: https://gcc.gnu.org/onlinedocs/gcc/c_002b_002b-extensions.html. there no extensions listed there work in manner you've described.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
