first steps with ECL

I am living in Austria now and my German is very basic, so I use online translators to cope with the occasional e-mail in German that I can't decipher. I am using the mutt mail user agent, and in the past I have configured it to open HTML attachments in Firefox. However, with plain text messages manual copy & paste became tedious, so I decided to write a little script that opens them in Firefox.

This gave me a good excuse to play around with ECL, something that I wanted to do for a while. The choice of CL as a scripting language might seem odd to some people, but I find it is optimal for me. I am aware that there are DSLs for this specific purpose (called "scripting languages") out there, and some even look like Lisp. However, I find that it takes a bit of time to find my way around a new language, and since at this point I am convinced that I will keep using CL as my main programming language, learning a scripting language that gives no additional insight would be a wasted effort.

Here is the end result. The script is really simple, and it benefited quite a bit from the comments of people on comp.lang.lisp. I like using this script, but the greatest benefit I derived from writing it is discovering what a gem ECL is. For example, I only need to use the two simple commands

(compile-file "savebody.lisp" :system-p t)
(c:build-program "savebody" :lisp-files '("savebody.o"))

to compile the script to a small (37K) (I am serious — it is really that small) executable file via C. A nice summary of simple compilation cases can be found here. Reading the ECL manual, I found that there are even more powerful facilities for building programs.

I am very impressed with ECL, and will definitely consider it as a remarkable implementation in the future.
