Practical Lisp 2008

A little more than three years ago there was a thread in comp.lang.lisp about what people were working on in Common Lisp. I found the replies, some summarized here, quite inspirational; they were from people doing practical stuff (even Real Work) with Common Lisp, beyond things like going through Project Euler or doing exercises from SICP. (Not that those aren't fine things to do, but.)

Let's update this. What are you using Common Lisp for in 2008? What are you using to do it? I'll start:

I mostly use Common Lisp to make graphics toys at Wigflip.com. To that end I'm always looking for new ways to produce or consume graphics-related things. For example, I'm adding support for processing OpenType fonts to ZPB-TTF and making a hybrid of Skippy and Vecto to produce simple vector-oriented animations. I'd also like to add APNG support to ZPNG.

I primarily use SBCL on Linux, x86 and x86-64, with Emacs and SLIME. For deploying all my website stuff I use Edi-ware extensively: Hunchentoot, HTML-TEMPLATE, and CL-WHO. I use CLSQL for a few things too. For graphics work, I use mostly my own libraries.

How about you? Leave a comment and let me know.




It aint dead

I work for www.cleartrip.com. The site mostly runs on CL. We use Allegro CL (earlier we did use CMUCL for some time). The UI rendering, the booking engines, the supplier integration, the payment gateways - all CL. Small parts of the site are done in RoR. We use hunchentoot, cl-ppcre, html-template, cl-memcached and lots of other lisp libraries. Company started with using a canned product made with Java+Oracle. We then replaced parts of it in parallel, proved better performance and stability and were then commissioned (so to speak).

We started with only me but now have about 10 lispers. Things learned : Freshers pick up lisp pretty fast if given simple guidance. You can build very high performance systems with CL. You can build very flexible and maintainable systems in CL.
