Greetings,
After several years playing with Common Lisp and building company
tools with it, I've finally used it to a public app. The CL engine
creates a PDF map of the stars and planets, with several thousand
stars in their right places, as seen from a particular time and place:
http://greaterskies.com
The idea is that it is a neat present. I've made it so that the price
is chosen by the user, and part of it (also chosen by the user) goes
to charity.
It's been great fun to write the lisp code, and deploying it with sbcl
in AWS has been a breeze.
Best,
jm

you used (in addition to SBCL)? Do you have anything written about your
experience using Common Lisp? Do you intend to share any CL software or
libraries as a result of the work you did for the product?
Thanks,
Zach

I haven't written about it yet, but it has been great. Common Lisp has
been my first-choice language for many years now, and I am certain
that I writing it in any other language would have been more time
consuming and less reliable.

Yes. I still need to figure out what to do with it, but at the very
least I'll publish the postscript generation library I wrote. It
needs some clean-up, though :-).
Thanks for the nice comments!

Not that many tools. I used the great cl-ppcre to parse the HYG stars

It's motivating to see projects of this type being done in Common
Lisp. It's a good advertisment in favour of CL.
i will consider of ordering an personalized present :-)

Ah, I thought you might be using CL-PDF for that. Do you generate

postscript and then convert?
