jmurmel VS adventofcode

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?

Code on GitHub is currently a mess.

In the spirit of the Day 5 ALLEZ CUISINE! challenge to ELI5 (Explain Like I'm Five), here's a tasty explanation of how my algorithm works using only a large bucket of Red Vines and a knife. It says to use lined paper, but if you try this at home consider aligning things on a cutting board.

Bonus solution in Go (golang) because I was confused about why my Elixir solution didn't work and decided to implement from scratch in case I'd done something dumb. The Go one also got the wrong answer, but took less than 100ms instead of a minute, so I could try out lots of tweaks that didn't change the answer.

Elixir 2031/2641 after 3.25/6.5 hours! Code on GitHub

I spent time this afternoon sprucing up my helpers for the iex REPL. I spent a bunch of time poking at things in IEx the last couple days and wanted to make sure I would minimize keystrokes if I needed to debug things on my phone while drunk. Turns out Thursday night > Friday night > Saturday night in terms of difficulty, so all those macros have so far saved me zero seconds :-)
