jmurmel VS lang

See also format.lisp for what I have so far. This will also run with sbcl and/ or abcl. If you've made it this far I'd also appreciate feedback on whether my chosen subset (see the comment at the top of the file) of Common-Lisp's format is somewhat useful and/ or which features you would miss the most.

JMurmel also has commandline flags to turn off language features for experimentation purposes, see e.g. implementing cons, car and cdr in Lambda Calculus.

To my defense, I have started my Lisp compiler/ interpreter mostly for recreational purposes to do the exact opposite of what the checkstyle nazis at my $job demand.

Murmel:

I may be a little late to the party but here's my Murmel solution:

Code is on Github, the latest release with a precompiled jar is at Release V 1.3.

Re: automated tests; there are JUnit tests in https://github.com/mayerrobert/jmurmel/tree/master/lambda/src/test/java, and the files in https://github.com/mayerrobert/jmurmel/tree/master/lambda/src/test/lisp are run automatically, too, and their output and result is checked. Maybe I should add a file HACKING.md or something that gives an intro of the project structure and build system?

This program will print its own source code: Try running it with the tools provided by the Standard Lang implementation of the Lang programming language! (Check out the Standard Lang implementation on GitHub: lang) A REPL environment known as the LangShell is included in the repository.
