Subject: GNU Mes 0.19 released <#secure method=pgpmime mode=sign> We are pleased to announce the release of GNU Mes 0.19, representing 100 commits over 10 weeks. Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap a GNU/Linux system without binary GNU toolchain or equivalent) and work is ongoing to audit and verify this bootstrap path in NixOS. This release introduces strings as byte-array, hash-tables and native structs. While that does increase the footprint somewhat, it fixes our performance issue; tinycc is now compiled in ~8min (WAS: ~1h30). Next targets: - translate mes.c into unsnarfed mes.M2 - use Gash to remove bash, coreutils&co, grep, sed, tar from the Guix bootstrap binaries - replace the NixOS bootstrap - use dietlibc, uClibc, ... for bootstrapping GNU (bash, binutils, gcc, tar) and remove Mes C lib+gnu? - bootstrap gcc-3.x or 4.x directly, drop initial gcc-2.95.3 target? - have M1+hex2 create gcc/tcc-usable object files? archives? - Debian? - ARM, the Hurd? Packages are available from Guix's core-updates branch. * About GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to Guix[2] and potentially to any other interested GNU/Linux distribution, and aims to help create a full source bootstrap as part of the bootstrappable builds[3] effort. It consists of a mutual self-hosting Scheme interpreter written in ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme. This mes.c is being simplified[4] to be transpiled by M2-Planet[5]. The Scheme interpreter (mes.c) has a Garbage Collector, a library of loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS [portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --and test suite just barely enough to support a simple REPL and simple C-compiler: MesCC. Mes+MesCC can compile an only lightly patched TinyCC[9] that is self-hosting. Using this tcc and the Mes C library we now have a Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5, binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap Guix for i686-linux and x86_64-linux. 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] ~500 byte self-hosting hex assembler. * Download git clone git://git.savannah.gnu.org/mes.git Here are the compressed sources and a GPG detached signature[*]: https://ftp.gnu.org/gnu/mes/mes-0.19.tar.gz https://ftp.gnu.org/gnu/mes/mes-0.19.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/mes/mes-0.19.tar.gz https://ftpmirror.gnu.org/mes/mes-0.19.tar.gz.sig Here are the MD5 and SHA1 checksums: 99e134df87adc5fc5fd2c04941929c23 mes-0.19.tar.gz c9781b3b6a814acc985c2ac68caa111a56583bca mes-0.19.tar.gz [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify mes-0.19.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273 and rerun the 'gpg --verify' command. Mes runs from the source tree and can also be built, packaged and installed in Guix from a git checkout by running guix package -f .guix.scm * Get informed, get involved See https://bootstrappable.org Join #bootstrappable on irc.freenode.net. * Changes in 0.19 since 0.18 ** Core *** The build system has been simplified. *** Mes now prints a backtrace upon error. *** Performance has been improved 2-8 times, making Mes 2-10 times slower than Guile. *** Mes now supports a module type and uses a `boot-module'. *** Mes now supports a hash_table type. *** Mes now supports a struct type. *** Mes now supports building a %bootstrap-mes seed from Guix. ** Language *** Records are now implemented using struct (WAS: vector). *** 44 new functions ceil, char-downcase, char-set-adjoin, char-set-complement, char-upcase, current-time, delete-file, dup, dup2, file-exists?, floor, frame-printer, get-internal-run-time, getcwd, gettimeofday, hash, hash-ref, hash-set!, hash-table-printer, hashq, hashq-get-handle, hashq-ref, hashq-set, inexact->exact, make-hash-table, make-stack, make-struct, module-define!, module-printer, module-ref, module-variable, read-line, round, stack-length, stack-ref, string-downcase, string-tokenize, string-upcase, struct-length, struct-ref, struct-set! struct-vtable, struct-vtable, with-error-to-file. ** MesCC *** Assembly defines have been cleaned-up: duplicates deleted, missing added, wrong fixed. *** MesCC now supports compiling GNU Bash and GNU Tar. **** 6 New functions getegid, geteuid, getppid, setgid, setuid, sigdelset, sigprocmask. **** 22 New macros EACCES, ENOSPC, ESPIPE, INT16_MAX, INT16_MIN, INT32_MAX, INT32_MIN, INT64_MAX, INT64_MIN, INT8_MAX, INT8_MIN, LLONG_MAX, LLONG_MIN, SIZE_MAX SYS_getegid, SYS_geteuid, SYS_setgid SYS_setuid, S_IRGRP, S_IROTH, S_IRWXG, S_IRWXO S_ISGID, S_ISUID, S_IWGRP, S_IWOTH, S_IXGRP, S_IXOTH, UINT16_MAX, UINT32_MAX, UINT64_MAX, UINT8_MAX, _POSIX_VERSION. ** Noteworthy bug fixes *** Mes now supports characters #\xNN. *** Mes now supports assq-ref and assoc-ref with alist == #f. *** Mes now supports \xNN in strings. This allows using Nyacc-0.86.0. *** MesCC now supports the unary plus operator. *** MesCC now supports the `U' integer suffix. *** MesCC now comes with INTnn_MIN/MAX, UINTnn defines in stdint.h. *** MesCC now always exits non-zero when assembler or linker fail.
