chain

for a code like this let anotherFolder='whatever'; let anotherFolder2='whatever'; chrome.bookmarks.create( {title:'whatever2'}, function( parentFolder ) { chrome.bookmarks.move( anotherFolder, {parentId: parentFolder.id}, function() { chrome.bookmarks.removeTree( anotherFolder2, function() { resolve(); }); }); }); can I transform it to chain functions? Something like let anotherFolder='whatever'; let anotherFolder2='whatever'; return new Promise(function(resolve){ chrome.bookmarks.create( {title:'whatever2'}, function( parentFolder ) { resolve(parentFolder); }).then( (parentFolder) => { chrome

I have my application that should open a popup ask a confirmation at the user, then make an ajax cal and close the popup. I tried to do it using a chain of promise (I've already used it, and I remember that it should work in this way), but it seems to block after the call to reservationService.confirm($scope.object); . Now it is a fake service implemented with a setTimeout and $q just to return a promise (in future it will make the ajax call). Is this a valid code or I didn't undestood how promise works? For the popup I choose AngularUI and the code is this: reservationService.book($scope

Is it possible to ignore a catch and return back to the chain? promiseA() // <-- fails with 'missing' reason .then(promiseB) // <-- these are not going to run .then(promiseC) .catch(function(error, ignore){ if(error.type == 'missing'){ ignore() // <-- ignore the catch and run promiseB and promiseC } }) Is something like this possible? Here's the synchronous analogy: try { action1(); // throws action2(); // skipped action3(); // skipped } catch (e) { // can't resume } vs try { action1(); // throws } catch (e) { handleError(e); } action2(); // executes normally action3(); Here's the promise

Like in this other question , I want to create a celery group from a list that's returned by a celery task. The idea is that the first task will return a list, and the second task will explode that list into concurrent tasks for every item in the list. The plan is to use this while downloading content. The first task gets links from a website, and the second task is a chain that downloads the page, processes it, and then uploads it to s3. Finally, once all the subpages are done, the website is marked as done in our DB. Something like: chain( get_links_from_website.si('https://www.google.com'),

I want to find ALL the paths starting and ending from/to a specific node. I would like that each node in a path appears only once. For example, in a graph like this: (a)-[:REL]->(b)-[:REL]->(c)-[:REL]->(a) (a)-[:REL]->(e)-[:REL]->(f)-[:REL]->(a) (e)-[:REL]->(b) grafically: e → b ↙ ↖ ↗ ↘ f → a ← c Cypher code: CREATE (a { name:'A' })-[:REL]->(b {name:'B'})-[:REL]->(c { name:'C' }) -[:REL]->(a)-[:REL]->(e {name:'E'})-[:REL]->(f {name:'F'})-[:REL]->(a), (e)-[:REL]->(b) I would like that the research of chains starting from (a) returns (a)->(b)->(c)->(a) (a)->(e)->(f)->(a) (a)->(e)->(b)->(c)->(a)

Update: this issue was a result of jQuery 1.7 vs 1.8. Do not ever use promises in 1.7 beacuse they aren't chainable with returning a promise inside a .then . 1.8 looks like they didn't mess it up. http://jsfiddle.net/delvarworld/28TDM/ // make a promise var deferred = $.Deferred(); promise = deferred.promise(); // return a promise, that after 1 second, is rejected promise.then(function(){ var t = $.Deferred(); setTimeout(function() { console.log('rejecting...'); t.reject(); }, 1000); return t.promise(); }); // if that promise is successful, do this promise.then(function() { console.log('i

I'm trying to use FileReader to read several files sequentially using promises for that. The problem is that I need to divide the reading operations in several chunks to make them doable. By doing so, I lose the Promise chain. This is what happen in the following code, where I get the console log here , then catched (meaning I've lost the chain), then inside and then finished . Somehow the Promise in upload is not respected. Here it is the code (please go to the last EDIT, I keep the original text nonetheless) var reader = new FileReader(); reader.onloadend = function(e) { if (e.target
