is there ruby equivalent of c/c++ macro? #define somethingelse ruby projects typically have neither pre-processing nor compilation step , usage of pre-processor not common. you can define constants using capitalized variable names. however, if need pre-processor can use cpp ruby or other language - not care actual syntax.

i have task in school have answer question: "a couple of students make calendar program days "absolute daynumber" defined amount of days january 1st year 0 current day. on many smaller computers maximum value int 32767. can happen if disregard this? how can solve issue?" the question kind of confuses me. work in python , have read python automatically handles int overflows converting int long , other programming languages similar things (like example wrapping around negative number, aka 32768 becomes -32767). if programming languages didn't automatically handle overflows imagine error if number goes on 32767... right? if wanted print "absolute daynumber" (assuming on 32767 , can use int's) wouldn't able because can't store value in int. impossible. if wanted print today's date take pc bios or use unix time instead. for me seems answer question depends on want program do. teacher says no. says none of answers correct. don...

i have large project i've been refactoring use webpack , es6 modules. many of dependencies using commonjs or amd modules, i'm requiring them old way. for example, const pikaday = require("pikaday"); unfortunately, when run webpack --progress it looks webpack trying parse every single file in path. several warnings like, example: module parse failed: /path/to/node_modules/pikaday/index.html eventually, following error: error in ./~/pikaday/tests/methods.js module not found: error: cannot resolve module 'expect.js' in /users/myuser/web/myproject/node_modules/pikaday/tests i'm getting error tests directory in dependency, don't care parsing bundle. why webpack trying parse every file in path, , how correct behavior? for clarity, i'll post important parts of webpack.config.js file here. var webpack = require("webpack"); var path = require("path"); module.exports = { entry : { main : ...

i have variables bound this in controller, , in route designation use controlleras: 'game' . allows me include them in html {{game.var}} . sometimes, bind objects want display, forces me write repeatedly {{game.object.a}} , {{game.object.b}} , {{game.object.c}} . in previous project using meteor, set data context with keyword. {{#with object}} {{a}} {{b}} {{/with}} but don't see similar feature in angular. closest i've been able make work adding attribute ng-repeat="object in [game.object]" . works, isn't semantic. causes me quick flash of second element when game.object changes, new 1 loads before first 1 erased. is there better solution problem? angular intentionally uses context scope avoid confusion between parent , child scopes. if you're not using child scopes, can skip controller syntax entirely , bind $scope in model, turns game.a , game.b a , b in view. if using child scopes, can still skip controlleras, bec...

conventional wisdom async void ok in event handlers works great in gui-driven applications (e.g. wpf). however, i've been bitten assumption when working different sort of event handlers. consider application event handler gets called result of external event, such rabbitmq message or third party integration library. presumably, event handler gets called kind of dispatcher loop. if code in event handler synchronous, - needs finish executing before event handler can fire again. if event handler async void , each call event handler fire-and-forget, , many execute in parallel. it case don't want behaviour. example, if processing messages rabbitmq queue, want process messages in order. yet, able await asynchronous calls. how can have asynchronous event handlers , yet still have them executed sequentially? update : came across blog post stephen cleary describes same problem i'm having. however, if understand correctly, suggested use of deferrals assumes have con...
