I am pleased to announce the release of Mes 0.5, representing 249
commits over 4 months. Mes is now self-hosting, or rather it features
a mutual self-hosting Scheme interpreter and C compiler: mes.c and
mescc; a Nyacc-based C compiler backend that also works separately
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
It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
a library of loadable Scheme modules-- notably Dominique Boucher's
LALR, Pre-R6RS portable syntax-case with R7RS ellipsis, Matt
Wette's Nyacc 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 was inspired by The Maxwell Equations of Software: LISP-1.5
-- John McCarthy page 13, GNU Guix's source/binary packaging
transparency and Jeremiah Orians's stage0 bootstrap project.
git clone https://gitlab.com/janneke/mes
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.5 -O
Mes runs from the source tree and can also be built, packaged and
installed in Guix[SD] by the usual
guix package -f guix.scm
