Mes -- Maxwell Equations of Software
Mes aims to create full source bootstrapping for GuixSD: an entirely
source-based bootstrap path. The target is to [have GuixSD] boostrap
from a minimal, easily inspectable binary --that should be readable as
source-- into something close to R6RS Scheme.
It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
[Guile] Scheme.
The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
library of loadable Scheme modules-- notably [[https://github.com/schemeway/lalr-scm][Dominique Boucher's LALR]],
[[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][Pre-R6RS portable syntax-case]] with R7RS ellipsis, [[http://www.nongnu.org/nyacc/][Matt Wette's Nyacc]]
and [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][Guile's PEG]] --and test suite just barely enough to support a
simple REPL (repl.mes) and simple C-compiler (mescc.mes) that can
produce the second initial ELF binary from binary from mes.c, in only
about 2h30'.
Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%25201.5%2520Programmers%2520Manual.pdf][LISP-1.5]] -- John
McCarthy page 13, [[https://www.gnu.org/software/guix/][GNU Guix's]] source/binary packaging transparency and
[[https://github.com/oriansj/stage0][Jeremiah Orians's stage0]] bootstrap project.
