Subject: Mes 0.6 released
|
|
|
|
|
|
|
|
|
|
I am pleased to announce the release of Mes 0.6, representing 32
|
2017-05-14 16:09:22 +00:00
|
|
|
commits over 17 days. Mescc now works with vanilla Nyacc 0.78.3
|
2017-05-06 15:46:41 +00:00
|
|
|
(thanks Matt!), Nyacc has been unbundled and Mescc compiles 33/55
|
|
|
|
|
of tinycc test2 tests.

* About
|
|
|
|
|
|
|
|
|
|
Mes aims to create full source bootstrapping for GuixSD: an
|
|
|
|
|
entirely source-based bootstrap path. The target is to [have
|
|
|
|
|
GuixSD] boostrap from a minimal, easily inspectable binary --that
|
|
|
|
|
should be readable as source-- into something close to R6RS
|
|
|
|
|
Scheme.
|
|
|
|
|
|
|
|
|
|
It currently consists of a mutual self-hosting [close to Guile-]
|
|
|
|
|
Scheme interpreter prototype in C and a Nyacc-based C compiler in
|
|
|
|
|
[Guile] Scheme.
|
|
|
|
|
|
|
|
|
|
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
|
|
|
|
|
a library of loadable Scheme modules-- notably Dominique Boucher's
|
|
|
|
|
LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt
|
|
|
|
|
Wette's Nyacc[3] Guile's PEG[4] --and test suite just barely
|
|
|
|
|
enough to support a simple REPL (repl.mes) and simple C-compiler
|
|
|
|
|
(mescc.mes) that can produce the second initial ELF binary from
|
|
|
|
|
binary from mes.c, in only about 2h30'.
|
|
|
|
|
|
|
|
|
|
Mes was inspired by The Maxwell Equations of Software: LISP-1.5[5]
|
|
|
|
|
-- John McCarthy page 13, GNU Guix's[6] source/binary packaging
|
|
|
|
|
transparency and Jeremiah Orians's stage0[7] bootstrap project.

Mes runs from the source tree and can also be built, packaged and
|
|
|
|
|
installed in Guix[SD] by the usual
|
|
|
|
|
|
|
|
|
|
guix package -f guix.scm
