We are happy to announce the release of GNU Mes 0.26. It's been only a month since the previous release mainly because most this work has been waiting for 0.25 to be released. This release represents 194 commits over one year by two people. This release brings Guile module support and support for running Gash and Gash-Utils.
We are excited that the NLnet Foundation is sponsoring this work! What's next? Bringing the Full Source Bootstrap to NixOS. Remove indirect Guile dependencies (via Gash and Gash-Utils) from the Mes bootstrap in Guix. Support for bootstrapping gcc-4.6.4, and a Full Source Bootstrap for armhf-linux, and riscv64-linux. Enjoy! * About GNU Mes is a Scheme interpreter and C compiler for bootstrapping the GNU System. It has helped to decimate the number and size of binary seeds that were used in the bootstrap of GNU Guix 1.0. Recently, version 0.24.2 has realized the first Full Source Bootstrap for Guix <https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/>. The final goal is to help create a full source bootstrap as part of the bootstrappable builds effort <https://bootstrappable.org> for any UNIX-like operating system. Mes + MesCC + Mes C Library can build a bootstrappable TinyCC <https://gitlab.com/janneke/tinycc> that is self-hosting. Using this bootstrappable-tcc and the Mes C library we can build an ancient version of the GNU tools 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 was inspired by The Maxwell Equations of Software: LISP-1.5 -- John McCarthy page 13, Guix's source/binary packaging transparency and Jeremiah Orians's Stage0 <https://github.com/oriansj/stage0>, a ~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-0.26.tar.gz https://ftp.gnu.org/gnu/mes/mes-0.26.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/mes/mes-0.26.tar.gz https://ftpmirror.gnu.org/mes/mes-0.26.tar.gz.sig Here are the SHA1 and SHA256 checksums: 581d7dba5f9749dd232a203d04175494ded0e77d mes-0.26.tar.gz 0f2210ad5896249466a0fc9a509e86c9a16db2b722741c6dfb5e8f7b33e385d4 mes-0.26.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-0.26.tar.gz.sig The signature should match the fingerprint of the following key: pub rsa4096 2018-04-08 [SC] 1A85 8392 E331 EAFD B8C2 7FFB F3C1 A0D9 C1D6 5273 uid Jan (janneke) Nieuwenhuizen <jann...@gnu.org> If that command fails because you don't have the required public key, or that public key has expired, try the following commands to retrieve or refresh it, and then rerun the 'gpg --verify' command. gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273 As a last resort to find the key, you can try the official GNU keyring: wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg gpg --keyring gnu-keyring.gpg --verify mes-0.26.tar.gz.sig * Changes in 0.26 since 0.25.1 ** Core *** Mes now has a Guile-compatible record interface. *** Mes now has a Guile-compatible hash-table interface. *** Mes now uses exceptions instead of asserts. *** Mes now supports Guile-compatible modules and variable lookup. *** The reader now supports `#\fs', `#\nl', and `#\np'. *** Mes now supports vectors in syntax-rules. *** Dynamic-wind was fully implemented. *** Mes now has regex support. *** Mes now supports functional record setters. *** simple-format now supports `~%'. *** Charsets can now be used in `string-index'. *** The (srfi srfi-14) module was completed. **** 9 new modules (ice-9 ftw), (ice-9 i18n), (ice-9 receive), (ice-9 regex), (rnrs io ports), (rnrs bytevectors), (srfi srfi-2).
