Subject: GNU Mes 0.20 released <#secure method=pgpmime mode=sign> We are pleased to announce the release of GNU Mes 0.20, representing 147 commits over 38 weeks. Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap a GNU/Linux system without binary GNU toolchain or equivalent). It should land in Guix master any day now: a big thank you to everyone who helped, notably Ludovic and Mark. This release is a step towards the upcoming Scheme-only bootstrap and bringing Mes into NixOS and Debian. This effort is now sponsored by NLnet[12]. Next targets: - ARM support - Reduced Binary Seed bootstrap for ARM - Scheme-only bootstrap: use Guile and Gash to remove bash, coreutils&co, grep, sed, etc. from the Guix bootstrap binaries - mes-m2: port Mes.c to M2-Planet - Introduce Reduced Binaries Seed bootstrap to NixOS - Debian? - Hurd Packages are available in Guix master. * About GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to GNU 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-0.20.tar.gz https://ftp.gnu.org/gnu/mes/mes-0.20.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/mes/mes-0.20.tar.gz https://ftpmirror.gnu.org/mes/mes-0.20.tar.gz.sig Here are the MD5 and SHA1 checksums: df839a83e4a2ad6c2a4accc5bf17b1a7 mes-0.20.tar.gz 38d4cb3fa28fa1f5fc57fea9e046d4d8052bbb8c mes-0.20.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-0.20.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. * Get informed, get involved See https://bootstrappable.org Join #bootstrappable on irc.freenode.net. * Changes in 0.20 since 0.19 ** Core *** The build system has been simplified, again. Mes now builds ootb on Debian. *** Mes now supports -c EXPR. ** Divide by zero is now flagged. ** Language *** 1 new function: take-while. ** MesCC *** The C libraries have been exploded into one function per file. *** MesCC now has enhanced POSIX/gcc comand line support, e.g. -DFOO=1, -nodefaultlibs, -nostartfiles, -nostdlib. *** The archiver is now called `mesar'. *** MesCC now supports Nyacc-0.99. *** MesCC now depends on MesCC-Tools 0.6.0. *** 1 new function __mesabi_uldiv. ** Noteworthy bug fixes *** interger division has been fixed. *** isatty now looks at terminfo. *** signal now uses sigaction correctly for non-x86. *** string->number now support #x hex-prefix. *** ungetc now has a buffer per file handle.
