We are thrilled to announce the release of GNU Mes 0.24, representing
|
|
|
|
|
222 commits over one year by four people.
|
|
|
|
|
|
|
|
|
|
Mes has now been ported to M2-Planet and can be bootstrapped using
|
|
|
|
|
stage0-posix[0], starting from the 357-byte hex0 binary of the
|
|
|
|
|
bootstrap-seeds[1], as was promised at FOSDEM'21[2].

We are excited that the NlNet Foundation[4] is again sponsoring this
|
2022-05-01 20:49:51 +00:00
|
|
|
work!
|
|
|
|
|
|
|
|
|
|
What's next?
|
|
|
|
|
|
|
|
|
|
Work to integrate this so-called "Full Source Bootstrap" is happening on
|
|
|
|
|
the wip-full-source-bootstrap[3] branch. Also, full Guile compatible
|
|
|
|
|
module support, and RICS-V support.
|
|
|
|
|
|
|
|
|
|
Enjoy!

* About
|
|
|
|
|
|
|
|
|
|
GNU Mes[5] is a Scheme interpreter and C compiler for bootstrapping
|
|
|
|
|
the GNU System. Since version 0.22 it has again helped to halve the
|
|
|
|
|
size of opaque, uninspectable binary seeds that are currently being
|
|
|
|
|
used in the Reduced Binary Seed bootstrap[6] of GNU Guix[7]. The
|
|
|
|
|
final goal is to help create a full source bootstrap as part of the
|
|
|
|
|
bootstrappable builds[8] effort for UNIX-like operating systems.
|
|
|
|
|
|
|
|
|
|
The Scheme interpreter is written in ~5,000 LOC of simple C, and the C
|
|
|
|
|
compiler written in Scheme and these are mutual self-hosting. Mes can
|
|
|
|
|
now be bootstrapped from M2-Planet[9] and Mescc-Tools[10].
|
|
|
|
|
|
|
|
|
|
Mes has a Garbage Collector, a library of loadable Scheme modules--
|
|
|
|
|
notably Dominique Boucher's LALR[11], Pre-R6RS portable
|
|
|
|
|
syntax-case[12] with R7RS ellipsis, Matt Wette's Nyacc[13] --and test
|
|
|
|
|
suite, just enough to support a REPL and a C99 compiler: mescc.
|
|
|
|
|
|
|
|
|
|
Mes + MesCC + Mes C Library can build a bootstrappable TinyCC[14] 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, x86_64-linux, armhf-linux and aarch64-linux.
|
|
|
|
|
|
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[15] --
|
|
|
|
|
John McCarthy page 13, GNU Guix's source/binary packaging transparency
|
|
|
|
|
and Jeremiah Orians's stage0[16] 357-byte self-hosting hex assembler.

[*] Use a .sig file to verify that the corresponding file (without the

and the corresponding tarball. Then, run a command like this:

gpg --verify mes-0.24.tar.gz.sig

or that public key has expired, try the following commands to update

or refresh it, and then rerun the 'gpg --verify' command.

|
|
|
|
|
*** The Mes C library now supports an argv bigger than 255.
|
|
|
|
|
*** Development build support with Guile-2 was resurrected.
