Hashtag and Username Linking in Twitter Apps

Andrew — Tue, 12 May 2009 23:44:50 +0000

Are you trying to add automatic hashtag and username hot linking in your PHP twitter app?

I just tried to do this with my amdavidson.me lifestreaming site. It’s just two nested regular expressions. If there’s some problem with nested preg_replace functions, or if any regular expression geniuses have better ideas, feel free to comment.

But if not, here’s a little code for you, should make things super easy. It assumes your tweet variable is $tweet, replace with whatever you’d need.

1
2
3
4
5

echo preg_replace('/\#([a-zA-Z0-9_]{1,15})?/',
"\"http://hashtags.org/tag/$1\">#$1",
preg_replace('/\@([a-zA-Z0-9_]{1,15})?/',
"\"http://twitter.com/$1\">@$1",
$tweet));

Sweetcron Stream Updating Cron Job

So the Sweetcron documentation isn’t altogether clear on what you should put in cron for it to update automatically, rather than slowing down a user every 30 minutes.

It’s fairly intuitive, but for those missing this logical step, do the following.

Change the setting in the admin panel from psuedo-cron to true-cron, and take note of the URL.

Then put the following in your crontab file (easily accessed with ‘crontab -e’ on a debian machine):

1	/5 * * * curl http://your/true-cron/url

You can change the 5 to be the number of minutes between updates that you want, and you’ll definitely want to change the URL to the one listed in your Sweetcron’s admin page.

Lifestreaming via Sweetcron

Had a Tumblr setup for a while at amdavidson.me but I already have a webserver and didn’t like dealing with another host.

So I searched around a bit and Sweetcron came up as a viable alternative for an aggregator for all my internet activities. It’s a pretty cool little app, very lightweight and seems to be pretty extensible, if I get around to it.

Anyways, check it out, it has a good summary of all the useless stuff that I do on the internet, all three of the blogs, my twitter account, my delicious bookmarks, and my flickr pictures. One stop shopping.
