#+TITLE: About GNU Mes

#+SUBTITLE: Maxwell Equations of Software

[[https://www.gnu.org/software/mes][GNU Mes]] brings a [[http://joyofsource.com/reduced-binary-seed-bootstrap.html][Reduced Binary Seed bootstrap]] to [[https://www.gnu.org/software/guix][Guix]] and potentially
to any other interested GNU/Linux distribution, and aims to help
create a full source bootstrap as part of the [[http://bootstrappable.org][bootstrappable builds]]
effort.

It 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 (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]] --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-2.95.3.  This is enough to bootstrap Guix for
i686-linux and x86_64-linux.

Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%201.5%20Programmers%20Manual.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.

GNU Mes is free software, it is distributed under the terms of the GNU
General Public Licence version 3 or later.  See the file [[file:COPYING][COPYING]].

* Get it

   #+BEGIN_SRC bash
   git clone git://git.savannah.gnu.org/mes.git
   #+END_SRC

* Build it (see [[file:INSTALL][INSTALL]] for full instructions)

   #+BEGIN_SRC bash
   ./configure
   make all
   make check
   #+END_SRC

* REPL it

   #+BEGIN_SRC bash
   src/mes.gcc-out            # default (64 bit) gcc-compiled
   src/mes.mes-gcc-out        # 32 bit, gcc -nostdlib, Mes C Lib
   src/mes.mes-out            # 32 bit, bootstrapped, mes.M1+MesCC-compiled
   src/mes.x86_64-mes-gcc-out # 64 bit, gcc -nostdlib, Mes C Lib
   src/mes.x86_64-mes-out     # 64 bit, bootstrapped, mes.M1+MesCC-compiled
   #+END_SRC

* MesCC compiler

   #+BEGIN_SRC bash
   ./pre-inst env mescc -c scaffold/main.c
   #+END_SRC
