Mes 0.27.2 is a bug-fix release. It represents 76 commits by five people over one year. This release supports development builds with gcc-16 and adds support for using NYACC versions 2.02.4 and 3.00.0.
This release really prepares for 0.28 that will bring the compiler and a massive rewrite of the Mes core; stay tuned! We are most grateful for NLnet sponsoring this work. 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 gcc-4.6. This is enough to bootstrap Guix for i686-linux, x86_64-linux, armhf-linux, aarch64-linux, and riscv64-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 ~300-byte self-hosting hex assembler. ================================================================== DOWNLOAD git clone git://git.savannah.gnu.org/mes.git Here is the GNU mes home page: https://gnu.org/s/mes/ For a summary of changes and contributors, see: https://git.sv.gnu.org/gitweb/?p=mes.git;a=shortlog;h=v0.27.2 or run this command from a git-cloned mes directory: git shortlog v0.27.1..v0.27.2 Here are the compressed sources and a GPG detached signature: https://ftp.gnu.org/gnu/mes/mes-0.27.2.tar.gz https://ftp.gnu.org/gnu/mes/mes-0.27.2.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/mes/mes-0.27.2.tar.gz https://ftpmirror.gnu.org/mes/mes-0.27.2.tar.gz.sig Here are the SHA1 and SHA256 checksums: 76ab84f70ff2cec4c7975b6b93647d2bc537350a mes-0.27.2.tar.gz f77a0037a82d5d1756b99154c5fefe7c1fe8bebae0e2e4c37f2f455e2750eeb0 mes-0.27.2.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-0.27.2.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 <[email protected]> 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-0.27.2.tar.gz.sig Alternatively, Mes can be installed using GNU Guix: guix pull guix install mes NEWS * Changes in 0.27.2 since 0.27.1 ** Core *** Cast functions were removed. *** Several pre-1.13.1 M2-Planet workarounds were removed. ** Build *** Mes now requires M2-Planet >= 1.13.1. *** Mes is now installable as a Guix channnel: guix time-machine \ --channels=https://cgit.git.savannah.gnu.org/cgit/mes.git/tree/build-aux/channels.sh \ -- shell mes *** GNUmakefile supports building `.go' files directly *** Running the test suite during bootstrap, with Gash, is now supported *** Mes now builds with gcc-16. ** Mes *** 6 new functions were added: string-copy!, vector-copy!, vector-copy!, vector-fill!, vector-fill, vector-fold-right. ** MesCC *** MesCC now works with NYACC versions 2.02.4 and 3.00.0 *** MesCC now ignores some common options: -f*, -M*, -W*. *** MesCC now fails early when pre-processing fails. ** Mes C Library *** 13 prototypes were added: clearerr, ctime, fileno, freopen, getpwnam, mktmp, rewind, setbuf sigblock, sigemptyset, sigsetmask strdup, ttyname. *** The v*printf and v*scanf prototypes were moved to stdio.h ** Noteworthy bug fixes *** The build system no longer compiles each file twice This was a tracing regression/typo introduced in v0.20 *** A bug in string-every was fixed and made more efficient. *** A bug in define-private was fixed. *** A workaround for a hygiene problem in `or' using `r' was added. *** The reader now skips escaped newline characters.
