My Code Archive

Over the years, I’ve written a bunch of Perl and PHP code for my own personal use. Some of it might be useful to others, some of it might be useless. Some of it doesn’t even work. It might be educational for folks who want to learn Perl or PHP, or need examples of how to code something.

Anyway, I wanted to put it all in one place so that people could find it and use it, if it is of any use. I’ve had fun writing up this archive, because I’ve come across some code that I wrote a long time ago, when I was ignorant of better ways to do things… but interesting code nonetheless. If you do end up using any of this code, take a minute and leave a comment on this entry. I’d love to know what folks are using this stuff for.

I’ll try to keep this entry up-to-date if I add or remove any code from the archive.

Enjoy!

Notes:
Scripts that end in .phps are PHP source. They should be renamed to end in .php to run on your system. Scripts that end in .txt are (most likely) Perl source. They can be named whatever you like, but for consistency should probably be renamed to end in .pl. To view the source, click on the name of the script.

This code is distributed without any warranty or any guarantee that it will work. Unless noted, there is no documentation. I might be able to help you use it, but I make no guarantee of that, either.

***spamhauschecker|http://prwdot.org/code/spamhauschecker.txt***: Perl script that checks whether a given IP address is listed on Spamhaus. Uses the Net::DNS::Resolver Perl module.

***tag_glue|http://prwdot.org/code/tag_glue.txt***: Perl MovableType Plugin that ‘glues’ together the contents of a given tag. Useful for joining Technorati tags together.

***PhotoManip|http://prwdot.org/code/PhotoManip.txt***: Perl script that takes a list of images from standard input, and performs some manipulations on them. Uses the Image::Magick Perl module.

***blacklist_update|http://prwdot.org/code/blacklist_update.txt***: This is a good one. Perl script that actually simulates logging into a Movable Type installation, going to MT-Blacklist, and running a manual blacklist update. This was written for an old version of MT, and an old version of MT-Blacklist, and before I knew how to actually use MT and MTBL’s built-in modules. But it’s a good example of how to use WWW::Mechanize to perform automated, command-line browsing.
