Evil Perl Scripts’O’Doom
Here are a couple of very petite scripts I’ve written to fulfill very specific needs. I might add to them, but I don’t need anything right now.
1. Searchenginator.
I don’t know where this script is. So forget I mentioned it.
2. Happy Log Entry Thing.
Likewise, forget I said anything.
3. Luscious RSS Parsing Goodness
These both do more or less the same thing – which is parse an RSS file and output HTML – they’re both here, and they’re both as messy as fuck, and commented badly etc, because I’m stuffed if I can be bothered sorting them out right now. (It’s Christmas Eve, you see).
Either can be used, probably. news.pl will definitely work, but you’ll have to find the RSS file yourself, Moreover can provide one, no doubt. You can either use an SSI to execute the script, which will then include the resultant HTML in your document, or you can use a shell script (on a cron, perhaps) to run it every 30 minutes or 2 hours, or whatever seems appropriate, pipe the HTML into a file, then include that in your document.
Whatever you do, let me know. I’d be very interested to hear if anyone finds this interesting at all. I don’t remember where I got the original file I built this on, might have been from IBM or someone. *shrug*.
