tl;dr Composer just got better at posting tweets, so post full urls instead of shortening.
Twitter automatically parse out any domain name or url in a tweet and replaces it with a
t.co link. If you type something like
twitter.com your 11 character domain gets converted into (currently) a 22 character
Until today, Composer wasn’t very good at understanding this. Sometimes, it would shorten your post before sending it to twitter when it wasn’t necessary. And worse, with the introduction of images, sometimes posts to twitter would fail. If you add an image, you lose (currently) 23 characters from your tweet because twitter posts a link to the image (22) plus a space (1).
So, from today, we’ve built custom handlers just for twitter. We parse out any domain or url, replace it with (currently) 23 characters, and then check if your tweet is <140.
This means, if you post a massive url to twitter, it gets auto shortened on twitter’s side, and now Composer is smart enough to figure that out. So if you’re posting links to Facebook, Twitter and WordPress, post the full url, no need to use a shortener.
Two caveats, we’re a little conservative because twitter’s
t.co links are 22 characters for
http links and 23 for
https links. So we assume all links are 23 just to be on the safe side. Also, we parse out all domains (like
github.io) which Twitter doesn’t. I filed a bug.
This was made substantially easier thanks to twitter-text-php, thanks to its authors.
