Subject: GNU Mes 0.20 released
|
|
|
|
<#secure method=pgpmime mode=sign>
|
|
|
|
We are pleased to announce the release of GNU Mes 0.20, representing
|
|
147 commits over 38 weeks.
|
|
|
|
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
|
|
a GNU/Linux system without binary GNU toolchain or equivalent). It
|
|
should land in Guix master any day now: a big thank you to everyone who
|
|
helped, notably Ludovic and Mark.
|
|
|
|
This release is a step towards the upcoming Scheme-only bootstrap and
|
|
bringing Mes into NixOS and Debian. This effort is now sponsored by
|
|
NLnet[12].
|
|
|
|
Next targets:
|
|
|
|
- ARM support
|
|
- Reduced Binary Seed bootstrap for ARM
|
|
- Scheme-only bootstrap: use Guile and Gash to remove bash,
|
|
coreutils&co, grep, sed, etc. from the Guix bootstrap binaries
|
|
- mes-m2: port Mes.c to M2-Planet
|
|
- Introduce Reduced Binaries Seed bootstrap to NixOS
|
|
- Debian?
|
|
- Hurd
|
|
|
|
Packages are available in Guix master.
|
|
|
|
* About
|
|
|
|
GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GNU Guix[2]
|
|
and potentially to any other interested GNU/Linux distribution, and
|
|
aims to help create a full source bootstrap as part of the
|
|
bootstrappable builds[3] 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[4] to be transpiled by M2-Planet[5].
|
|
|
|
The Scheme interpreter (mes.c) has a Garbage Collector, a library of
|
|
loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
|
|
[portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test
|
|
suite just barely enough to support a simple REPL and simple
|
|
C-compiler: MesCC.
|
|
|
|
Mes+MesCC can compile an only lightly patched TinyCC[9] 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: LISP-1.5[10] -- John
|
|
McCarthy page 13, GNU Guix's source/binary packaging transparency and
|
|
Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.

|
[*] 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-0.20.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.
