Subject: GNU Mes 0.21 released
|
|
|
|
<#secure method=pgpmime mode=sign>
|
|
|
|
We are pleased to announce the release of GNU Mes 0.21, representing
|
|
54 commits over 10 weeks.
|
|
|
|
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
|
|
a GNU/Linux system without binary GNU toolchain or equivalent). See
|
|
https://guix.gnu.org/blog/2019/guix-reduces-bootstrap-seed-by-50/
|
|
|
|
This release supports a Scheme-only bootstrap: Mes can now be built with
|
|
Gash and the experimental Gash Core Utils instead of using GNU Awk, GNU
|
|
Bash, the GNU Core Utilities, GNU Grep, GNU Gzip, GNU Make, GNU SED, and
|
|
GNU Tar. Also, the Mes C Library now supports bootstrapping those.
|
|
Finally, this release brings Mes as a package to Debian GNU/Linux.
|
|
|
|
We are excited that the Nlnet Foundation[12] is now sponsoring this
|
|
work!
|
|
|
|
Next targets:
|
|
|
|
- Introduce the Reduced Binaries Seed bootstrap to NixOS (Debian,
|
|
Gentoo, ...?)
|
|
- Scheme-only bootstrap: use Guile, Gash and Gash Core Utils to remove
|
|
awk, bash, core utilities, grep, gzip, make, sed, tar, etc. from the
|
|
Guix bootstrap binaries
|
|
- ARM support
|
|
- Full Source Bootstrap: compile Mes.c using M2-Planet
|
|
- Reduced Binary Seed bootstrap for ARM
|
|
- the Hurd
|
|
|
|
Packages are available in Guix master.
|
|
|
|
* About
|
|
|
|
GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GNU Guix[2].
|
|
This bootstrap has halved the size of opaque, uninspectable binaries
|
|
that were needed to bootstrap Guix 1.0. The final goal is to help
|
|
create a full source bootstrap as part of the bootstrappable builds[3]
|
|
effort for any interested UNIX-like operating system.
|
|
|
|
Mes consists of a mutual self-hosting Scheme interpreter written in
|
|
~5,000 LOC of simple C, and a C compiler written in Scheme. This
|
|
mes.c is being simplified[4] to be transpiled by M2-Planet[5].
|
|
|
|
The Scheme interpreter 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 enough to support a REPL and a C99 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-0.21.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.
