11 GNU Mes --- Maxwell Equations of Software
13 [[https://www.gnu.org/software/mes][GNU Mes]] aims to help create full
14 source bootstrapping for GNU/Linux distributions such as
15 [[https://www.gnu.org/software/guix][GuixSD]] as part of the
16 [[http://bootstrappable.org][bootstrappable builds]] effort.
18 It currently consists of a mutual self-hosting Scheme interpreter
19 written in ~5,000 LOC of simple C and a Nyacc-based C compiler written
20 in Scheme. This mes.c is [[https://github.com/oriansj/mes-m2][being simplified]] to be transpiled by
21 [[https://github.com/oriansj/m2-planet][M2-Planet]].
23 The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
24 library of loadable Scheme modules-- notably Dominique Boucher's [[https://github.com/schemeway/lalr-scm][LALR]],
25 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]],
26 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
27 REPL and simple C-compiler: MesCC.
29 Mes+MesCC can compile an only [[http://gitlab.com/janneke/tinycc][lightly patched TinyCC]] that is
30 self-hosting. Using this tcc and the Mes C library we now have a
31 reduced-binary-seed bootstrap for the gnutools triplet: glibc-2.2.5,
32 binutils-2.20.1, gcc-4.1.0.
34 GNU 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]] --
35 John McCarthy page 13, GNU Guix's source/binary packaging transparency
36 and Jeremiah Orians's [[https://github.com/oriansj/stage0][stage0]] ~500 byte self-hosting hex assembler.
38 Mes is free software, it is distributed under the terms of the GNU
39 General Public Licence version 3 or later. See the file COPYING.
