javascript and string manipulation w/ utf-16 surrogate pairs

Javascript uses UCS-2 internally, which is not UTF-16. It is very difficult to handle Unicode in Javascript because of this, and I do not suggest attempting to do so. As for what Twitter does, you seem to be saying that it is sanely counting by code point not insanely by code unit. Unless you have … Read more

Dynamically change Tweet Button “data-text” contents

I struggled with this for a couple of hours this morning, but finally got it working! The problem is essentially that you can only include the twitter widgets.js script once in the page, and that script evaluates the data-text attribute on load. Therefore, in your example, you dynamically set the data-text attribute before loading the … Read more

syntaxError: ‘continue’ not properly in loop

continue is only allowed within a for or while loop. You can easily restructure your function to loop until a valid request. def writeHandlesToFile(): while True: with open(“dataFile.txt”,”w”) as f: try: lst = tweepy.Cursor(tweepy.api.followers,screen_name=”someHandle”,).items(100000) print “cursor executed” for item in lst: f.write(item.screen_name+”\n”) break except tweepy.error.TweepError as e: print “In the except method” print e time.sleep(3600)

Twitter Call back URL

Android action bar like twitter sample

Yet another action bar implementation can be found here (shameless plug), https://github.com/johannilsson/android-actionbar. It’s implemented as a library project so there’s no need to copy-paste resources. Implementation wise it’s built as a widget that extends a RelativeLayout with it own layout for the actions and the bar. This makes it possible to add it to layouts … Read more

Is there a callback for Twitter’s Tweet Button?

Twitter has Web Intent events for loaded, rendered, resize, tweet, follow, retweet, like, and click. twttr.events.bind( ‘tweet’, function (event) { // Do something there } ); The behavior was changed in the fall of 2015 due to the unreliableness of callbacks happening after an event is complete. They will now be triggered when a user … Read more

Character countdown like on twitter

Make a span and textarea and give them unique selectors (using an ID or class) like so: <textarea class=”message” rows=”2″ cols=”30″></textarea> <span class=”countdown”></span> And then make an update function like so: function updateCountdown() { // 140 is the max message length var remaining = 140 – jQuery(‘.message’).val().length; jQuery(‘.countdown’).text(remaining + ‘ characters remaining.’); } And make … Read more
