Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

format vs. formatter - using and implementing
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.

Murmel 1.4.1
JMurmel also has commandline flags to turn off language features for experimentation purposes, see e.g. implementing cons, car and cdr in Lambda Calculus.

Java OSS with the WORST code quality youโve ever seen?
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.

I may be a little late to the party but here's my Murmel solution:
-
I made a Lisp
Code is on Github, the latest release with a precompiled jar is at Release V 1.3.

Would welcome feedback on Murmel 1.0
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?

[2021 Day 6 (Part 2)] [Rust] Pretty darn elegant
nice one! you can make it even faster by creating a compile time multiplication table as i have done here, so all that happens at runtime is the bucketing of similarly aged fish, 7 multiplications + a sum

[2022 Day 14 (Part 2)] Oสฐ(Nยฒ)แตแตแตแต!... OH YEAH!
you've still got some overhead in your code, my rust solution creates a dense lookup array at runtime & takes ~200us on my 10850k. are you including file IO and printing to stdout?
