<div class="PlainText">We are pleased to announce the release of GNU Mes 0.18, representing<br>
83 commits over 8 weeks.<br>
<br>
Mes is now bringing a Reduced Binary Seed bootstrap to GuixSD; the<br>
size of bootstrap binaries has been halved and no regular toolchain<br>
binaries are used as binary seeds (i686-linux and x86_64-linux only).<br>
<br>
MesCC has been refactored to use an abstracted assembly language and<br>
can now (cross-)build x86_64 binaries.<br>
<br>
Next targets:<br>
<br>
- reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source<br>
- revive Gash/Geesh and use it to decimate the remaining bootstrap<br>
binary seeds<br>
- and/or otherwise reduce the bootstrap binaries<br>
- ARM, the Hurd?<br>
<br>
Packages are available from Guix's core-updates-next branch.<br>
<br>
* About<br>
<br>
GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GuixSD[2] and<br>
potentially to any other interested GNU/Linux distribution, and aims<br>
to help create a full source bootstrap as part of the<br>
bootstrappable builds[3] effort.<br>
<br>
It consists of a mutual self-hosting Scheme interpreter written in<br>
~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.<br>
This mes.c is being simplified[4] to be transpiled by M2-Planet[5].<br>
<br>
The Scheme interpreter (mes.c) has a Garbage Collector, a library of<br>
loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS<br>
[portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test<br>
suite just barely enough to support a simple REPL and simple<br>
C-compiler: MesCC.<br>
<br>
Mes+MesCC can compile an only lightly patched TinyCC[9] that is<br>
self-hosting. Using this tcc and the Mes C library we now have a<br>
Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,<br>
binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap GuixSD for<br>
i686-linux and x86_64-linux.<br>
<br>
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John<br>
McCarthy page 13, GNU Guix's source/binary packaging transparency and<br>
Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.<br>

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