I'm happy to move to savannah when Mes becomes a GNU package.

** Brief description of the package:
|
||
|
|
|
||
|
|
Mes aims to help create full source bootstrapping for GuixSD as part of
|
||
|
|
the bootstrappable builds effort (See https://bootstrappable.org/).
|
||
|
|
|
||
|
|
It currently consists of a mutual self-hosting Scheme interpreter
|
||
|
|
prototype written in C and a Nyacc-based C compiler written in Scheme.
|
||
|
|
This C prototype is being simplified to be transpiled by M2-Planet.
|
||
|
|
|
||
|
|
Mes+MesCC can compile an only lighty patched TinyCC 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-4.1.0.
|
||
|
|
|
||
|
|
* Code
|
||
|
|
** Dependencies:
|
||
|
|
|
||
|
|
Mes can be built as a regular package, or as part of the full source
|
||
|
|
(currently: reduced binary seed) bootstrap process.

** Configuration, building, installation:
|
||
|
|
|
||
|
|
*** Guix build, install
|
||
|
|
|
||
|
|
guix build mes, guix package --install mes
|
||
|
|
|
||
|
|
*** Regular build
|
||
|
|
|
||
|
|
./configure; make; make check; make install
|
||
|
|
|
||
|
|
*** Bootstrap build
|
||
|
|
|
||
|
|
<set env vars>
|
||
|
|
sh build.sh
|
||
|
|
sh check.sh
|
||
|
|
sh install.sh
|
||
|
|
|
||
|
|
** Documentation:
|
||
|
|
|
||
|
|
Mes does not yet have any documentation other than AUTHORS, HACKING,
|
||
|
|
INSTALL, NEWS, README. When it does, it will be in Texinfo: I live in
|
||
|
|
Emacs. I have initiated the GNU LilyPond documentation and website,
|
||
|
|
which are written in texinfo.
|
||
|
|
|
||
|
|
** Internationalization:
|
||
|
|
|
||
|
|
Mes does not have Internationalization. As it's an early bootstrap
|
||
|
|
package, it's unsure if it will ever get that. I do have experience
|
||
|
|
with adding Internationalization to GNU LilyPond.
|
||
|
|
|
||
|
|
** Accessibility:
|
||
|
|
|
||
|
|
None.
|
||
|
|
|
||
|
|
** Security:
|
||
|
|
|
||
|
|
Mes will be used as a critical link in our GNU bootstrapping chain.
|
||
|
|
It is essential for Mes to get a proper review before it is put in
|
||
|
|
place.
|
||
|
|
|
||
|
|
* Licensing:
|
||
|
|
|
||
|
|
GNU GPL 3, or later.

||

There are similarities with GNU Guile and to a lesser extent also with
|
||
|
|
MIT/GNU Scheme and SCM; in fact Mes' scheme tries to be compatible with
|
||
|
|
Guile Scheme. GNU Guile is about 30x faster than Mes.
|
||
|
|
|
||
|
|
The main difference is that mes.c is ~5,000LOC of very simple C and can
|
||
|
|
can be bootstrapped almost entirely from source, without any binary
|
||
|
|
seed. Currently, it needs a ~1MB ASSCI seed.
|
||
|
|
|
||
|
|
Guile is ~100,000LOC of full-blown C, not counting its dependencies
|
||
|
|
such as libgc.
|
||
|
|
|
||
|
|
Another difference with regular Scheme implementations, is that Mes does
|
||
|
|
not strive for RXRS compliance, instead it strives for minimalism and
|
||
|
|
Guile compatibility.
|
||
|
|
|
||
|
|
If in doubt, please contact the GuixSD or Guile maintainers.

* Any other information, comments, or questions:
|
||
|
|
|
||
|
|
I am an original author of GNU LilyPond and current GuixSD developer. I
|
||
|
|
have regular discussions about Mes and GuixSD with GuixSD and Guile
|
||
|
|
maintainers.
|
||
|
|
|
||
|
|
Mes currently targets only x86-linux, I would like some help to look at
|
||
|
|
other architectures and esp. at targeting the Hurd.
