Subject: Mes 0.13 released
|
|
|
|
|
|
|
|
|
|
I am pleased to announce the release of Mes 0.13, representing 45
|
|
|
|
|
commits over 3 weeks. MesCC can now compile a functional tcc when
|
|
|
|
|
running on Mes (in ~1h45') or on Guile (in ~3min).
|
|
|
|
|
|
|
|
|
|
This means that we are getting very close to a full source bootstrap
|
|
|
|
|
of tcc: it is now built without gcc, glibc or guile; using only
|
|
|
|
|
MesCC-tools and Mes sources and corresponding ascii/binary seeds.
|
|
|
|
|
|
|
|
|
|
* About
|
|
|
|
|
|
|
|
|
|
Mes[0] aims to help create full source bootstrapping for GuixSD[1]
|
|
|
|
|
as part of the bootstrappable builds[2] project.
|
|
|
|
|
|
|
|
|
|
It currently consists of a mutual self-hosting Scheme interpreter
|
|
|
|
|
prototype in C and a Nyacc-based C compiler in Scheme. This C
|
|
|
|
|
prototype is being simplified to be transpiled by M2-Planet[3].
|
|
|
|
|
|
|
|
|
|
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
|
|
|
|
|
a library of loadable Scheme modules-- notably Dominique Boucher's
|
|
|
|
|
LALR[4], pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
|
|
|
|
|
Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
|
|
|
|
|
enough to support a simple REPL (repl.mes) and simple C-compiler
|
|
|
|
|
MesCC.
|
|
|
|
|
|
|
|
|
|
Mes+MesCC can compile a modified TinyCC[8] that is close to being
|
|
|
|
|
self-hosting. A GNU Ccc-compiled tcc is known[9] to compile GCC.
|
|
|
|
|
|
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10]
|
|
|
|
|
-- John McCarthy page 13, GNU Guix's source/binary packaging
|
|
|
|
|
transparency and Jeremiah Orians's stage0[11] ~300 byte self-hosting
|
|
|
|
|
hex assembler.

* Download
|
|
|
|
|
|
|
|
|
|
git clone https://gitlab.com/janneke/mes
|
|
|
|
|
|
|
|
|
|
wget https://gitlab.com/janneke/mes/-/archive/v0.13/mes-0.13.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

* Changes in 0.13 since 0.12
|
|
|
|
|
** Core
|
|
|
|
|
*** Bootstrapped Mes+MesCC can now compile a patched tcc in ~2h30' (~25,000 LOC).
|
|
|
|
|
*** MesCC scripts for Mes and Guile are now merged; executable is: `mescc'.
|
|
|
|
|
*** Mes now uses only one arena for stop-and-copy; doubles available size.
|
|
|
|
|
*** Mes now has a Guile-like command-line interface (mes.repl has been removed).
|
|
|
|
|
*** Mes now boots into a full Scheme by default.
|
|
|
|
|
*** Mes can now be compiled (MES_MINI=1) to boot into a minimal Scheme (~2000 cells).
|
|
|
|
|
*** Mes now creates less garbage in the reader and in
|
|
|
|
|
append2, append_reverse, reverse, reverse!, vector-for-each, vector-to-list, vector-map.
|
|
|
|
|
*** 5 new functions
|
|
|
|
|
append-reverse, chmod, ioctl, isatty, isspace, last_pair, reverse!.
|
|
|
|
|
** Language
|
|
|
|
|
*** 3 new functions
|
|
|
|
|
char-whitespace?, chmod, isatty?
|
|
|
|
|
** Noteworthy bug fixes
|
|
|
|
|
*** Two bugs in the jam scraper/garbage collector have been fixed.
|
|
|
|
|
*** equal2_p now uses tail call elimination.
|
|
|
|
|
*** Escaped characters in strings are now read and write'd correctly.
|
|
|
|
|
*** The repl now expands macros again.
