Also, full Guile compatible +module support, and RICS-V support. + +Enjoy! + +* About + + GNU Mes[5] is a Scheme interpreter and C compiler for bootstrapping + the GNU System. Since version 0.22 it has again helped to halve the + size of opaque, uninspectable binary seeds that are currently being + used in the Reduced Binary Seed bootstrap[6] of GNU Guix[7]. The + final goal is to help create a full source bootstrap as part of the + bootstrappable builds[8] effort for UNIX-like operating systems. + + The Scheme interpreter is written in ~5,000 LOC of simple C, and the C + compiler written in Scheme and these are mutual self-hosting. Mes can + now be bootstrapped from M2-Planet[9] and Mescc-Tools[10]. + + Mes has a Garbage Collector, a library of loadable Scheme modules-- + notably Dominique Boucher's LALR[11], Pre-R6RS portable + syntax-case[12] with R7RS ellipsis, Matt Wette's Nyacc[13] --and test + suite, just enough to support a REPL and a C99 compiler: mescc. + + Mes + MesCC + Mes C Library can build a bootstrappable TinyCC[14] 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, x86_64-linux, armhf-linux and aarch64-linux. + + Mes is inspired by The Maxwell Equations of Software: LISP-1.5[15] -- + John McCarthy page 13, GNU Guix's source/binary packaging transparency + and Jeremiah Orians's stage0[16] 357-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-0.24.tar.gz + https://ftp.gnu.org/gnu/mes/mes-0.24.tar.gz.sig + + Use a mirror for higher download bandwidth: + https://ftpmirror.gnu.org/mes/mes-0.24.tar.gz + https://ftpmirror.gnu.org/mes/mes-0.24.tar.gz.sig + + Here are the SHA1 and SHA256 checksums: + + xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mes-0.24.tar.gz + xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mes-0.24.tar.gz + + [*] Use a .sig file to verify that the corresponding file (without the + .sig suffix) is intact.
