Run gulp task after completion of other task

大城市里の小女人 提交于 2019-12-04 12:15:35
I have two sets of files, let's call them base and mods . The mods files override the base files, so when I run the gulp task related to base , I need to run the mods task directly after. My setup is something like this: gulp.task('base',function(){ return gulp.src('base-glob') .pipe(...) .pipe(gulp.dest('out-glob')) }); gulp.task('mods',function(){ return gulp.src('mods-glob') .pipe(...) .pipe(gulp.dest('out-glob')) }); So I want to run the mods task at the completion of the base task. Note that this is not the same as defining base as a dependency of mods , because if I'm only changing mods

Synchronous AJAX call fails on iPad, but not other platforms and browsers

Does anyone know why a synchronous ajax call would fail and give the following error on Safari on an iPad, but the same code works fine on all other platforms and browsers I've tested so far? NETWORK_ERR: XMLHttpRequest Exception 101: A network error occurred in synchronous requests. That error suggests that I'm attempting a cross-domain request, but I'm not; the requested URL is on the same host, and in fact it's a relative URL. Even in trivial tests, this fails on the iPad (and works on all other platforms and browsers, including Safari), so I'm confident I've ruled out any possibility of a

mp3 website player with synchronized playback (not streaming)

Want a player (easy enough to put up) that plays back a directory of mp3s in such a way that if you join at 3:33:33 pm, you hear what others hear, not track one. like a pseudo broadcast/stream. how do i achieve that - what looks nice / is probably minimizable / is easy? i am trying to use mirvling but no such luck. any ideas? It's unlikely you're going to find something to drop in place. Plus, this isn't typically handled on the client side of things. You neglected to specify what languages and what not that you are using, so I'll provide a general answer. There are two methods to accomplish

What methods are blocking in Javascript?

问题 I'm trying to override the standard confirm() method in Javascript (make a nice UI and stuff). I've read a 100 posts that it "can't be done", but I don't want to give up until I have given it a fair shot. :) So, the real problem is of course that the confirm() method must block all javascript execution until the user selects an option. So, what are the methods in Javascript that have blocking behavior? I've been able to come up with 5: alert() - does not suit me, because it displays an

Synchronous and asynchronous activities

拜拜、爱过 提交于 2019-12-04 10:37:09
问题 Can anyone help me to understand synchronous and asynchronous activities in Android? What is exactly meant by synchronous and asynchronous activity in Android? StartActivity , StartSubActivity and StartAcivityForResult start an activity synchronously or asynchronously, or can they behave in both ways? Please explain as I have gone through many articles but could not find any proper explaination over this. 回答1: First of all, only one activity can be running at a time on Android, so you'll

How to make Cordova synchronous

拈花ヽ惹草 提交于 2019-12-04 09:48:31
My problem is quite simple but I can't find anything online. I am finishing development of a phone app, and I am having some issues with Cordova because of the not-synchronous execution. As it is right now, I have to do something like this: var finishedFl = 0; cordova.exec( function(info) { .... [Function goes here] finishedFl = 1; }, function (info) { alert('Error'); }, 'Smapps', 'getInfo', []); While(finishedFl != 1){ wait; } anotherFunction(); I find this way of programming extremely troubling and obviously not that good. So the question is: Is there any way of making Cordova execution

Qt synchronous QNetworkAccessManager get

别来无恙 提交于 2019-12-04 09:34:51
What's the proper way to do a synchronous QNetworkAccessManager::get ? The qt wiki offers an approach, but states "it is not recommended to use this in real applications." The mailinglist offers a similar solution to the wiki. Yum may use something like this: QEventLoop loop; connect(_netReply, SIGNAL(finished()), &loop, SLOT(quit())); loop.exec(); The simple solution mentioned in the wiki and in the answer from yttrium is quite fragile since it doesn't handle all possible failure scenarios (such as proxy) and therefore shouldn't be used in a production environment, and unfortunately it has

How to understand the “synchronous” and “asynchronouns” messaging in JMS?

ぃ、小莉子 提交于 2019-12-04 08:23:05
问题 After reading some document of JMS, I totally puzzled by the phrase synchronous and asynchronouns . See this page: http://docs.oracle.com/cd/E19798-01/821-1841/bncdq/index.html Synchronous You use the receive method to consume a message synchronously. You can use this method at any time after you call the start method: connection.start(); Message m = consumer.receive(); connection.start(); Message m = consumer.receive(1000); // time out after a second To consume a message asynchronously, you

C# have async function call synchronous function or synchronous function call async function

问题 I'm writing a C# .Net 4.5 library for doing common sql database operations (backup, restore, execute script, etc.). I want to have both synchronous and asynchronous functions for each operation, as this library will be used by both console and GUI apps, but I don't want to duplicate code everywhere. So as I see it, I have two options: Write the code that does the work in a synchronous function, and then just wrap it in a task for the async function, like so: public void BackupDB(string server

Javascript - synchronizing after asynchronous calls

南楼画角 提交于 2019-12-04 08:19:16
问题 I have a Javascript object that requires 2 calls out to an external server to build its contents and do anything meaningful. The object is built such that instantiating an instance of it will automatically make these 2 calls. The 2 calls share a common callback function that operates on the returned data and then calls another method. The problem is that the next method should not be called until both methods return. Here is the code as I have implemented it currently: foo.bar.Object =
