2 Subject: GNU Mes 0.20 released
4 <#secure method=pgpmime mode=sign>
6 We are pleased to announce the release of GNU Mes 0.20, representing
7 147 commits over 38 weeks.
9 Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
10 a GNU/Linux system without binary GNU toolchain or equivalent).
12 This release is a step towards the upcoming Scheme-only bootstrap and
13 bringing Mes into NixOS and Debian. This effort is now sponsored by
19 - Reduced Binary Seed bootstrap for ARM
20 - Scheme-only bootstrap: use Guile and Gash to remove bash,
21 coreutils&co, grep, sed, etc. from the Guix bootstrap binaries
22 - mes-m2: port Mes.c to M2-Planet
23 - Introduce Reduced Binaries Seed bootstrap to NixOS
27 Packages are available in Guix master.
31 GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GNU Guix[2]
32 and potentially to any other interested GNU/Linux distribution, and
33 aims to help create a full source bootstrap as part of the
34 bootstrappable builds[3] effort.
36 It consists of a mutual self-hosting Scheme interpreter written in
37 ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
38 This mes.c is being simplified[4] to be transpiled by M2-Planet[5].
40 The Scheme interpreter (mes.c) has a Garbage Collector, a library of
41 loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
42 [portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test
43 suite just barely enough to support a simple REPL and simple
46 Mes+MesCC can compile an only lightly patched TinyCC[9] that is
47 self-hosting. Using this tcc and the Mes C library we now have a
48 Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5,
49 binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap Guix for
50 i686-linux and x86_64-linux.
52 Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John
53 McCarthy page 13, GNU Guix's source/binary packaging transparency and
54 Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.

71 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mes-0.20.tar.gz
73 [*] Use a .sig file to verify that the corresponding file (without the
74 .sig suffix) is intact. First, be sure to download both the .sig file
75 and the corresponding tarball. Then, run a command like this:
77 gpg --verify mes-0.20.tar.gz.sig
79 If that command fails because you don't have the required public key,
80 then run this command to import it:
82 gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
84 and rerun the 'gpg --verify' command.
86 * Changes in 0.20 since 0.19

89 Mes now builds ootb on Debian.
90 *** Mes now supports -c EXPR.
91 ** Divide by zero is now flagged.
96 *** The C libraries have been exploded into one function per file.
