Mes -- Maxwell Equations of Software
|
|
|
|
[[http://gitlab.comog/janneke/mes][Mes]] aims to help create full
|
|
source bootstrapping for GNU/Linux distributions such as
|
|
[[https://www.gnu.org/software/guix][GuixSD]] as part of the
|
|
[[http://bootstrappable.org][bootstrappable builds]] effort.
|
|
|
|
It currently consists of a mutual self-hosting Scheme interpreter
|
|
written in ~5,000 LOC of simple C and a Nyacc-based C compiler written
|
|
in Scheme. This mes.c is [[https://github.com/oriansj/mes-m2][being simplified]] to be transpiled by
|
|
[[https://github.com/oriansj/m2-planet][M2-Planet]].
|
|
|
|
The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
|
|
library of loadable Scheme modules-- notably Dominique Boucher's [[https://github.com/schemeway/lalr-scm][LALR]],
|
|
Pre-R6RS [[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][portable syntax-case]] with R7RS ellipsis, Matt Wette's [[https://www.nongnu.org/nyacc][Nyacc]],
|
|
Guile's [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][PEG]] --and test suite just barely enough to support a simple
|
|
REPL and simple C-compiler: MesCC.
|
|
|
|
Mes+MesCC can compile an only [[http://gitlab.com/janneke/tinycc][lightly patched TinyCC]] that is
|
|
self-hosting. Using this tcc and the Mes C library we now have a
|
|
reduced-binary-seed bootstrap for the gnutools triplet: glibc-2.2.5,
|
|
binutils-2.20.1, gcc-4.1.0.
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%2525201.5%252520Programmers%252520Manual.pdf][LISP-1.5]] -- John
|
|
McCarthy page 13, GNU Guix's source/binary packaging transparency and
|
|
Jeremiah Orians's [[https://github.com/oriansj/stage0][stage0]] ~500 byte self-hosting hex assembler.
