Subject: Mes 0.6 released
|
|
|
|
I am pleased to announce the release of Mes 0.6, representing 32
|
|
commits over 24 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=v0.6 -O mes-0.6.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 0.6 since 0.5
|
|
** Core
|
|
*** configure, build now supports x86 and development for arm with-courage.
|
|
** Language
|
|
*** Nyacc has been unbundled and is now a dependency.
|
|
*** Mes now supports case-lambda.
|
|
*** Mes reader now supports abbreviated form for return character #\cr.
|
|
*** 1 new function
|
|
string-index.
|
|
** Mescc
|
|
*** Mescc can be used on regular C sources, like tinycc's tests/test2 suite.
|
|
*** make check passes 33/55 of tinycc's test suite etest/test2 tests.
|
|
*** Mescc now recognizes `short' as a type.
|
|
*** Mescc now supports sizeof (<identifier>), sizeof(<expression>).
|
|
*** Mescc now respects enum field initializers and supports enum variables.
|
|
*** Mescc now supports binary constants .
|
|
*** Mescc now supports assignments from ==, != boolean expressions .
|
|
*** Mescc now supports &, ^.
|
|
*** Mescc now supports struct pointers.
|
|
*** Mescc now supports struct definition with immediatete variable declaration.
|
|
*** Mescc now supports calling (returning correctly from) void functions.
|
|
*** Mescc now handles case statements breaks without compound correctly.
|
|
*** Mescc now has better [int/pointer] array support.
|
|
*** Mescc now has better support for simple (non-array-)structs.
|
|
*** Mescc now supports multiple declarations in one statement like: int a,b;
|
|
**** 2 new mlibc functions
|
|
printf, strcpy.
|
|
** Noteworthy bug fixes
|
|
*** Installed mes and mes.repl now also run outside of source tree again.
