We are pleased to announce the release of GNU Mes 0.18, representing
83 commits over 8 weeks.
Mes is now bringing a Reduced Binary Seed bootstrap to GuixSD; the
size of bootstrap binaries has been halved and no regular toolchain
binaries are used as binary seeds (i686-linux and x86_64-linux only).
MesCC has been refactored to use an abstracted assembly language and
can now (cross-)build x86_64 binaries.
- reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
- revive Gash/Geesh and use it to decimate the remaining bootstrap
- and/or otherwise reduce the bootstrap binaries
- ARM, the Hurd?
Packages are available from Guix's core-updates-next branch.
GNU Mes brings a Reduced Binary Seed bootstrap to GuixSD and
potentially to any other interested GNU/Linux distribution, and aims
to help create a full source bootstrap as part of the
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 being simplified to be transpiled by M2-Planet.
The Scheme interpreter (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 --and test
suite just barely enough to support a simple REPL and simple
Mes+MesCC can compile an only 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 GuixSD for
i686-linux and x86_64-linux.
Mes is 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 ~500 byte self-hosting hex assembler.

Here are the compressed sources and a GPG detached signature[*]:
Use a mirror for higher download bandwidth:
Here are the MD5 and SHA1 checksums:
[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify mes-0.18.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
and rerun the 'gpg --verify' command.
Mes runs from the source tree and can also be built, packaged and
installed in Guix[SD] from a git checkout by running
guix package -f .guix.scm
