Subject: Mes 0.7 released
|
|
|
|
I am pleased to announce the release of Mes 0.7, representing 32
|
|
commits over 4 weeks. Mescc now behaves more like a regular C
|
|
compiler: supporting -E, -c, -o options and with a more complete set
|
|
of header files [stubs]; enough to work on compiling tinycc's tcc.c
|
|
albeit a somewhat modified version[8].
|
|
|
|
* 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=v0.7 -O mes-0.7.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 0.7 since 0.6
|
|
** Core
|
|
*** The minimal C reader is now always included; dependencies
|
|
on i686-unknown-linux-gnu-gcc and binary read-0-32.mo have been
|
|
dropped, these are now optional.
|
|
** Language
|
|
*** Mes reader now supports octal numbers #oXXX.
|
|
*** 10 new functions
|
|
current-output-port, getopt-long, negate, open-output-file,
|
|
option-ref, set-current-output-port, string-rindex, string-suffix?,
|
|
with-ouwith-output-to-file, with-output-to-port.
|
|
** Mescc
|
|
*** Mescc can now be installed and used alongside a gcc installation.
|
|
*** Mescc can now handle const anywhere.
|
|
*** Mescc now supports array fields in structs.
|
|
*** Mescc now supports forward declarations and typedef.
|
|
*** Mescc can now handle comments anywhere.
|
|
*** Mescc now supports addition and substraction for enum field values.
|
|
*** Mescc now supports anonymous enums.
|
|
*** Mescc now supports all C99 header files needed to compile tcc.c.
|
|
*** build: C sources are now preprocessed separately, then compiled and linked.
|
|
*** build: mlibc and C sources are now compiled separately and then linked.
|
|
*** mlibc has been moved from Scheme snippets into C.
|
|
*** Mescc now supports -c, -D, -E, -I and -o options.
|
|
**** open now supports optional third mode parameter.
|
|
** Noteworthy bug fixes
|
|
*** string-index now supports function predicate.
|
|
*** number->string for radix > 10 now produces `a' instead of `:'.
