i have method in instantiate array of objects derived same protocol. know if can iterate through array , execute common protocol method. pseudocode nsarray *implementations = @[/*impl1, impl2, impl3 instantiated here*/] (__________ * impl in implementations){ [impl protocolmethod] } my issue don't know how define type of object in blank in for-in loop because different classes. closest can think of "id" doesn't seem valid type because "pointer non-const type no explicit ownership." could this: for (nsobject<myprotocol>* impl in implementations) [impl protocolmethod] or even for (id<myprotocol> impl in implementations) [impl protocolmethod] i use first form it's bit more compile-time safe.

general question is: how parse string , eliminate punctuation , replace of them? i'm trying modify input text. case have normal text file, punctuation , want of them eliminated. if symbol . ! ? ... want replace "" string. i never used regex , tried string comparison, isn't sufficient cases. have trouble if there 2 punctuation marks; in text "the second day (the 4ht).", when have ). togheter. for example, given input expect following: input : [...] @ it!" speech caused excpected output : @ <s> speech caused every word in code added arraylist because need work later. thanks lot! fileinputstream fileinputstream = new fileinputstream("text.txt"); inputstreamreader inputstreamreader = new inputstreamreader( fileinputstream, "utf-8"); bufferedreader bf = new bufferedreader(inputstreamreader); words.add("<s>"); string s; while ((s = bf.readline()) != null) { string[] var = s.split("

this easy want make sure i'm doing correctly. i've been making bunch of wordpress sites using child themes , style.css in root folder of theme , i've been using in functions.php file <?php add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' ); function theme_enqueue_styles() { wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' ); } while file exists in parent theme i'm using, it's blank , realized css file being used different file name , nested in \theme-name\framework\css\site\stacks\theme-css.css opposed theme-name\style.css so child theme have recreate folder structure , place same named theme-css.css in same folder or call style.css , put in child themes root folder be? other advice helpful. thanks. to add stylesheet when in child theme, these 2 options/behaviors: // point style.css in child theme wp_enqueue_style( 'my_child_styles', get_stylesheet_direct

i've got gulp task browersify files. works bundling including angular.js file quite large. want pull angular.js out , load in index.html before bundled javascript file. i've done adding .external('angular') browserify call bundled resulting file not smaller, , when run app in browser, acts still trying load node angular package (error: uncaught error: cannot find module 'angular') below gulp task problem believe. function identity (input) { return input; } function bundler (watch, mocks) { var b = (watch ? watchify : identity)( browserify(watch && watchify.args) .external('angular') ); b.add(format('./%s', app)).add('babel/polyfill'); if (mocks) b.add(format('./%s/mock', app)); return b; } function bundle (bundler) { return bundler .bundle() .pipe(source('main.js')) .pipe(gulp.dest('dist/app')); } gulp.task('bundle', function () { var bundled = bu

i have used original helloworld app , change model helloworldmodel mainmodel. then required "http" when run app , klik button "updateaction" writes console , sets message. the http request doesn't anything. code: (main-view-model.js) var __extends = this.__extends || function(d, b) { (var p in b) if (b.hasownproperty(p)) d[p] = b[p]; function __() { this.constructor = d; } __.prototype = b.prototype; d.prototype = new __(); }; var observable = require("data/observable"); var http = require("http"); var mainmodel = (function(_super) { __extends(mainmodel, _super); function mainmodel() { _super.call(this); console.log("mainmodel called"); this.set("message", "last updated" + " 2015-07-22 00:00:00"); this.set("message2", "last updated" + " 2015-07-22 00:00:00"); } mainmodel.prototype.updateaction = function() { console.log("up

hi have read caching issues custom functions in google sheets, i'm trying understand why following update if cell changed: function doob(input){ return input * 2; } but not update: function doob(input){ var sheet = spreadsheetapp.getactivespreadsheet(); var range = sheet.getrange(input); var values = range.getvalues(); return values[0][0] * 2 ; } i need range in order use .getbackgroundcolor() of each cell. probably because in first function pass cellreference directly, =doob(a1) and in script value of cell used. in second, have pass range string (since want backgroundcolors, not after values of range, right ?) =doob("a1:b8") as know, custom functions suffer memoization. work around pass in range second time, without quotation marks. =doob("a1:b8", a1:b8) that second paramater 'dummy' paramater script nothing it. but: change in values in range should make custom function re-evaluate. don't know if gonna lot if f

in our c codebase have assertion macros such as: assert3(x, ==, y) // x=0, y=1 results in "main.c:45: 'x == y' (0 == 1) untrue" assert(x == y) // x=0, y=1 results in "main.c:45: 'x == y' untrue" clearly, assert3 form more helpful when you're trying debug after failure because tells values of variables were. however, whenever need more complex assertion (especially including || since can split ones && multiple assertions), assert(x == y || y != 0 || x == 2) , can no longer take advantage of awesome assert3 format. clearly, could build macro assert11(x, ==, y, ||, y, !=, 0, ||, x, ==, 2) , ideally i'd create single macro can handle variable number of arguments , figure out print on own. this, think i'd need macro filter out arguments logical operators doesn't try print values -- there way that? i've had feeling , thought along lines, turns out asserts things should never happen, doesn'

i aware of fact problem has been reported earlier , have used recommended solutions none has helped far. as mentioned in title, ondestroy() called every time screen turns off. doesn't happen if service on. application has fixed orientation , hence android:screenorientation="portrait" as per earlier suggestions, added android:configchanges="orientation|keyboardhidden" etc. implemented onconfigurationchanged() never gets called. two important points: we facing problem on 1 device in our test setup, samsung duo running 4.0.4. on other devices, not issue. this issue not happening other apps running on same device. will appreciate help. thanks update : seems setting these flag causing issue. removing them solves used reason other insight appreciated. intent.flag_activity_single_top | intent.flag_activity_no_history

how can find elements in redis empty have keys this: setting:1 setting:2 setting:442 etc how can search redis-cli bash script command if key contains empty value redis-cli keys \* | xargs -l 1 redis-cli get grep , check if value empty found solution redis-cli keys "settings:*" | xargs -l 1 redis-cli the notion of empty key in redis non-existent - there no empty keys in redis. if key "becomes" empty (e.g. list popped final element), key not exist in redis anymore. here's example: foo@bar:~$ redis-cli 127.0.0.1:6379> exists foo (integer) 0 127.0.0.1:6379> rpush foo bar (integer) 1 127.0.0.1:6379> exists foo (integer) 1 127.0.0.1:6379> lpop foo "bar" 127.0.0.1:6379> exists foo (integer) 0 127.0.0.1:6379>

i have different pages populate div tag specific id based on id inner text: here different example of pages div: <div id="id_name">text page1</div> <div id="id_name">text page2</div> <div id="id_name">text page3</div> i want take inner text of second , fill variable. i try use this: if($("#id_name").length > 0 && $("#id_name").text() === "text page2") { site.text = $("#id_name").text(); } do not use same id multiple elements. see why bad thing have multiple html elements same id attribute? use classes instead you can use :contains() if ($(".class_name:contains(text page2)").length > 0) { $('body').text("text page2"); } <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script> <div class="class_name">text page1</div> <d

is allowed? class a{ ... ... }; a; //global object int main() { a; // local object . . . . return 0; } here global object has been declared after class definition, local variable has been declared. ok? why? it's legal "hide" declaration of object, declaration in tighter scope. within main function, a refer local variable. outside main function, a refer global variable. as whether it's "ok" - "no". it's bad idea, in it's make code confusing, , more prone accidentally introducing bugs. wouldn't advise doing it.
