Subject: Mes 0.6 released
|
||||
|
||||
I am pleased to announce the release of Mes 0.6, representing 32
|
||||
commits over 10 days. Mescc now works with vanilla Nyacc 0.78.3
|
||||
(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.
|
||||
|
||||
* Download
|
||||
|
||||
git clone https://gitlab.com/janneke/mes
|
||||
|
||||
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.5 -O mes-0.5.tar.gz
|
||||
|
||||
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
