lisp
A mini Lisp in 1k lines of C with garbage collector, explained. Includes over 40 built-in Lisp primitives, floating point, strings, closures with lexical scope, macros, proper tail recursion, exceptions, execution tracing, file loading, a mark-sweep/compacting garbage collector and REPL.

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

SBCL: merge of mark-region GC
The Immix inspired mark-region GC developed by Hayley Patton (https://github.com/no-defun-allowed/swcl) got merged recently, which is pretty cool news for SBCL users.

Mini Lisp in under 1k lines of C: Cheney or mark-sweep GC, which is best?
I'm currently implementing Immix in SBCL (got generations working yesterday), but I wouldn't recommend one does that for a miniature implementation, as my implementation (though with hacks, performance tricks of dubious quality, and having to put the hysterical raisins somewhere) is about 1kLOC, and I haven't even gotten to writing compaction yet. A simple hybrid of mark-sweep and copying is the Lang-Dupont collector which copies one portion of the heap at a time, marking and reclaiming the rest in place.

Creator of SerenityOS announces new Jakt programming language
I say this while failing to design a parallel GC for SBCL for my second time; but I was unaware of the more clever RC schemes until recently, as nor myself nor my older colleagues seemed to have only used naive RC.

The self-hosted Zig compiler can now successfully compile itself
"the distributed system" is the first link, garbage collector is this link; again I wrote the backend for SICL as well as other parts, and I didn't say I made a language.

Microcontroller-based Lisp machine (minimum language needed)?
Lately, we run Robert van Engelen's 1k Lisp on ESP32 and 8266 boards: https://github.com/Robert-van-Engelen/lisp but we started on his tiny Lisp: https://github.com/Robert-van-Engelen/tinylisp (which is 99 lines of C)
