-Subject: on bootstrapping: introducing Mes
-Date: Sun, 19 Jun 2016 13:08:02 +0200
-
-Hi,
-
-I have a minimal LISP-1.5-resembling interpreter in C that now can
-also interpret itself
-
- https://gitlab.com/janneke/mes
-
-It was inspired by the seemingly often ignored bootstrapping question
-made so painfully visible by GuixSD and by OriansJ with their self
-hosting hex assembler project.
-
-As a next step after a hex assembler I was thinking of getting Scheme up
-and running and use that to create a tiny C compiler, probably using
-PEG. For that I think we need define-syntax, which I had a peek at and
-still scares the all-sorts-of-things out of me :-)
-
-I searched for minimal Lisp/Scheme to get that going and found an
-article called the Maxwell Equations of Software 1) with a pointer to
-the 1962 LISP 1.5 paper by John McCarthy 2).
-
-First I `implemented' Mes/LISP-1.5: the bottom half of page 13 and the
-necessary helper procedures defined on pages 8-12 using Guile, removing
-all but the primitives needed to run LISP-1.5/Mes (I think): car, cdr,
-cond, cons, define, eq?, '()/nil, null?, pair? and quote. I cheated
-with read, and with display and newline for debugging.
-
-Then I translated the program into C and got rid of read by using
-getchar/ungetchar.
-
-It's been great fun and now I'm kind of stuck a bit at the point of
-implementing macros. I have a simplistic version in C but want to
-remove that again --I like the idea of having the absolute minimal LISP
-interpreter in C-- and only introduce macros after having bootstrapped
-into the LISP/Mes domain.
-
-Greetings,
-Jan

-Subject: Mes 0.10 released
-
-I am pleased to announce the release of Mes 0.10, representing 82
-commits over 6 weeks. Mescc now compiles a bootstrappable-modified
-TinyCC into a mes-tcc that in turn can successfully compile a trivial
-C program.
-
-* About
-
- Mes[0] aims to create full source bootstrapping for GuixSD[1] as
- part of the bootstrappable builds[2] project.
-
- It currently consists of a mutual self-hosting [close to Guile-]
- Scheme interpreter prototype in C and a Nyacc-based C compiler in
- [Guile] Scheme. This C prototype will be rewritten in stage0[3]
- M1 assembly (or possibly stage2 slow-LISP, or ...).
-
- The Scheme interpreter prototype (mes.c) has a Garbage Collector,
- a library of loadable Scheme modules-- notably Dominique Boucher's
- LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
- Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
- enough to support a simple REPL (repl.mes) and simple C-compiler
- (mescc.mes).
-
- The simple C compiler can compile a modified TinyCC[8] that is
- starting to work! A gcc-compiled tcc is known[9] to compile GCC.
-
- 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 ~300 byte self-hosting
- hex assembler.

-
-Mes runs from the source tree and can also be built, packaged and
-installed in Guix[SD] by the usual
-
- guix package -f guix.scm
-
-* Changes in 0.10 since 0.9
- ** Core
- *** 2 new functions
- logand, lognot.
- ** Mescc
- *** Mes now includes M1 sources for full source bootstrapping up to tcc.
- *** Mescc now depends on Nyacc 0.81.0.
- *** Mescc now compiles a mes-tcc that compiles a trivial C to a running a.out.
- *** Mescc now supports several (as used my tinycc) struct by value assignments.

-I am pleased to announce the release of Mes 0.12, representing 120

-now run on Mes. Performance of Mes running MesCC has been improved by
-a factor of 100; mes.c (~3000 LOC) now compiles in ~4min. Many fixes
-and enhancements make that now also TinyCC parses (~1.5h) and compiles
-(~20min) with Mes+MesCC (Guile+MesCC takes ~2min).
-
-Special thanks go to Ricardo Wurmus for sharing the recursive macro
-expand perspective and starting work on that, to Han-Wen Nienhuys for

-Subject: Mes 0.15 released
-
-I am pleased to announce the release of Mes 0.15, representing 45
-commits over 3 weeks. The GNU toolchain is getting bootstrapped!
-
-As of 0.14, Mes+MesCC compiles a self-hosting TinyCC. Using the 0.15
-Mes C library, this TinyCC can build the GNU tools triplet:
-binutils-2.14, gcc-2.95.3, glibc-2.2.5.
-
-This means that we can build a GNU toolchain that depends only on a
-critical 1MB ASCII M1 seed. GuixSD currently uses a ~250MB binary
-seed to build gcc.
-
-Next targets are: upstream the Mes bootstrap to GuixSD, build a
-Gcc-4.7 and Glibc-2.23, bootstrap utilities like bison, flex, grep,
-sed..., replace GuixSD's bootstrap for x86 and reduce the 1MB ASCII M1
-seed to ~5000 LOC/~100KB of M2 source, which is a restricted subset of
-C.
-
-Packages are available from Guix's wip-bootstrap branch.
-
-* About
-
- Mes[0] aims to help create full source bootstrapping for GuixSD[1]
- as part of the bootstrappable builds[2] project.
-
- It currently consists of a mutual self-hosting Scheme interpreter
- prototype in C and a Nyacc-based C compiler in Scheme. This C
- prototype is being simplified to be transpiled by M2-Planet[3].
-
- The Scheme interpreter prototype (mes.c) has a Garbage Collector,
- a library of loadable Scheme modules-- notably Dominique Boucher's
- LALR[4], pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
- Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
- enough to support a simple REPL (repl.mes) and simple C-compiler
- MesCC.
-
- Mes+MesCC can compile an only slightly patched TinyCC[8] that is
- self-hosting. Using the Mes C library, this tcc can now build the
- GNU tools triplet: binutils-2.14, gcc-2.95.3, glibc-2.2.5.
-
- Mes is inspired by The Maxwell Equations of Software: LISP-1.5[9]
- -- John McCarthy page 13, GNU Guix's source/binary packaging
- transparency and Jeremiah Orians's stage0[10] ~300 byte self-hosting
- hex assembler.

-
- git clone https://gitlab.com/janneke/mes

-Mes runs from the source tree and can also be built, packaged and
-installed in Guix[SD] by the usual
-
- guix package -f guix.scm
-
-* Changes in 0.15 since 0.14
- ** Core
- *** Support fork, exec, waitpid.
- *** Boot-0 loading has been refactored.
- *** MesCC now has out of the box Geiser support.
- ** Language
- *** 2 new functions
- drop, drop-right.
- ** MesCC
- *** MesCC and Mes Lib C can now build binutils-2.30, gcc-2.95.3 and glibc-2.2.5.
- *** MesCC now provides dummy crti.o, crtn.o so that tcc needs not be patched for those.
- *** Mes Lib C now supports compiling glibc-2.2.25.
- *** Mes Lib C now supports compiling gcc-2.95.3
- *** Mes Lib C now supports compiling binutils-2.30.
- *** Mes Lib C now supports compiling m4-1.4.
- *** Mes Lib C has been split into archs: gcc, x86-mes-gcc and x86-mes.
- *** MesCC now has a posixy command line interface.
- **** 70 new functions
- abs, access, alarm, alloca, atexit, atol, bcmp, bcopy, brk, bzero,

-Subject: Mes 0.16 released
-
-I am pleased to announce the release of Mes 0.16, representing 27
-commits over 2 weeks.
-
-A most annoying ELF header bug was fixed that suddenly had all Mes
-binaries segfault before entering `_start' on Linux 4.17 and later.
-
-We now have binutils-2.20.1 and gcc-4.1.0, both compiled with
-gcc-2.95.3 and glibc-2.2.5.
-
-This reduced-binary-seed bootstrap still depends on these bootstrap
-binaries: BOOTSTRAP-GUILE, flex, bash, bzip2, coreutils, diffutils,
-gawk, grep, gzip, make, sed, tar, on the small binary seeds:
-tinycc-seed, mescc-seed and on the mes.M1 ASCII seed.
-
-Next targets:
-
- - build a Gcc 4.7 and Glibc 2.23
- - upstream the x86 Mes bootstrap to GuixSD
- - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
- - revive Gash: a posix shell for Guile to reduce the bootstrap binary
- dependencies
- - and/or otherwise reduce the bootstrap binary dependencies
-

- *** Mes Lib C now bootstraps glibc-2.2.5, binutils-2.20.1, gcc-4.1.0.
- *** MesCC binaries now run on Linux 4.17 too, i.e. survive Linus' new `sane mmap limits.'
- *** MesCC now runs with mescc-tools 0.5 (no = in long options).
- **** 3 new C test
- 88-strrchrc, 97-fopen.c, 98-fopen.c.
- ** Noteworthy bug fixes
- *** strrchr now stops when it reaches start of string.
- *** fopen now return 0 upon failure. Supports binutils' hack: fd=-2 means `cached'.
- *** vfprintf, vsprintf now support precision and width on integers strings better.
- *** fread now produces ungetc'd chars too.
- *** memcmp now supports comparing 0 bytes, supporting binutils.
-
- *** The unused ELF header data section, identical to the text section, has been removed.

-Subject: on bootstrapping: first Mes 0.3 released
-
-I am pleased to announce the first release of Mes: 0.3, representing
-152 commits over 3 months since the second status report[1].
-
-* About
-
- Mes aims to create an entirely source-based bootstrapping path. The
- target is to [have GuixSD] boostrap from a minimal, easily inspectable
- binary --that should be readable as source-- into something close to
- R6RS Scheme.
-
- As bootstrapping is presumably easiest and probably most fun with
- Scheme, the next step for Mes is mescc: a C compiler/linker to
- boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.
-
- It currently has an interpreter written in C (mes) with Garbage
- Collector (Jam Scraper), a library of loadable Scheme modules with
- test suite just barely enough to support a simple REPL (repl.mes)
- and a proof-of-concept c-compiler (mescc.mes) that produces an elf
- from the simplest of C files.

-installed in Guix[SD] by the usual
-
- guix package -f guix.scm
-
-
-* Changes in 0.3 since 0.2
- ** Core
- *** Number-based rather than pointer-based cells.
- *** Garbage collector aka Jam scraper.
- A variant on SICP's stop and copy Garbage Collector (Jam Scraper?)
- algorithm has been implemented.
- *** The reader has been moved to Scheme.
- ** Language
- *** Simple loadable modules.
- *** Srfi-9 and match use handwritten syntax-rules (mes-use-module (mes syntax)).
- *** Optional syntax-case using psyntax (mes-use-module (mes psyntax)).
- ** Noteworthy bug fixes
- *** Srfi-0 has been fixed.
-
-* Changes in 0.2 since 0.1
- ** Core
- *** Names of symbols and strings are list of characters [WAS: c-string].
- *** Sc-expand from pre-R6RS's psyntax has been integrated.
- *** Undefined variable error now shows the name of the undefined variable.
- *** There is now only one SCM type for builtin functions.
- *** Macro expansion has been cleaned-up.
- ** Language
- *** Mes now provides a subset of R6RS.
- *** Mes now provides syntax-case.
- *** Mes now provides `load'.
- ** Noteworthy bug fixes
- *** Using values as second parameter of builtin function yields first value.
- *** Quoted internals (e.g. 'if 'lambda) are now symbols.
- *** Syntax error now exits.
- *** Make+Bash voodoo has been replaced by build-aux/mes-snarf.scm.
- *** Apply now accepts multiple list arguments.
- *** Apply of character, inernal, number, string is an error.
- *** Quasisyntax reading
-
-* Changes in 0.1 (since progress report #2)
- ** Core
- *** expand_macro is now a separate function.
- *** A smaller core can now compiled using BOOT=1.
- The smaller core does not provide define, define-macro, or quasiquote;
- these are provided from a Scheme version of implemented eval/apply.
- ** Language
- *** Mes now provides a subset of R5RS.
- *** Mes now provides let-syntax.
- *** Mes now provides match.
- *** Mes now provides quasisyntax, unsyntax and unsyntax-splicing.
- ** User interface
- *** Mes now provides a REPL, run:
- scripts/repl.mes
- *** Mes compiler can be run as a script:
- scripts/mescc.mes doc/examples/main.c
- *** Macro expansion can be inspected in the REPL, e.g.:
- ,expand (and 0 1)
- ** Noteworthy bug fixes
- *** Performance: scripts/mescc.mes now takes 2s to compile main.c (was 1'20").
- *** Symbols are now truly unique.
- * '(), #t, #f are no longer symbols.

-Mes runs from the source tree and can also be built, packaged and
-installed in Guix[SD] by the usual
-
- guix package -f guix.scm
-
-* Changes in 0.4 since 0.3
- ** Core
- *** Improved performance.
- Macros are now memoized; after expansion and before eval'ing the
- expanded form, their input s-expression is replaced by the expansion.
- This yields a nice performance improvement which finally allowed
- moving all non-essential bits from the C-core into Scheme...including
- the reader. The Scheme reader is much, much slower than the previous
- C version, making Mes--again-- feel slow. Think of that as a feature.
- *** Bootstrap with minimal reader in C.
- The C-reader needs only support reading of words and lists
- (s-expressions), line-comments to read the initial Scheme reader which
- then takes over and handles reading of quoting, characters, strings,
- block-comments.
- *** Reduced size.
- Total C size: ~1500LOC. The main Mes evaluator is now ~1000LOC
- including cell creation and garbage collector. This code is able to
- execute a Scheme program that has been loaded into memory. Another
- ~500LOC is spent to load a minimal Scheme program and to dump it, to
- provide a small posix interface, math functions and do some error
- reporting.
- *** Programs can be dumped and loaded using --dump and --load.
- ** Language
- *** Minimal syntactic exception support for Nyacc.
- *** Minimal syntactic fluids support for Nyacc.
- *** Keywords are now supported.
- *** Cond now supports =>.
- *** Guile's optargs: lambda* and define* are now supported.
- *** #;-comments are now supported.
- *** Non-nested #| |#-comments are now supported.
- *** Quasisyntax is now supported.
- *** R7RS syntax-rules with custom ellipsis, with-ellipsis are now supported.
- *** 9 new [partial] modules
- (mes fluids), (mes nyacc), (mes optargs), (mes pmatch), (mes peg),
- (srfi srfi-13), (srfi srfi-9-psyntax), (srfi srfi-26), (srfi srfi-43),
- (rnrs arithmetic bitwise), (sxml xpath)
- *** 36 new functions
- 1+, 1-, abs, and=>, append-reverse, ash, char<=?, char<?, char>=?,
- char>?, even?, filter, delete, delq, vector-copy, fold, fold-right,
- getenv, iota, keyword->symbol list-head, list-tail, negative?, odd?,
- positive?, remove!, remove, string->number, string-copy,
- string-prefix?, string=, string=?, symbol->keyword symbol-append,
- symbol-prefix?, unless, write, zero?.
- ** Noteworthy bug fixes
- *** Macros are now memoized.
- *** An error is reported when using a wrong number of arguments with a call.
- *** Cond now evaluates its test clauses only once.
- *** Append can also handle one argument.
- *** For-each now supports 2 list arguments.
- *** Map now supports 3 list arguments.
- *** Backslash in string is supported.
- *** Closure is not a pair.
- *** All standard characters are supported.
- *** Mescc now also runs in Guile.

-Subject: Mes 0.7 released
-
-I am pleased to announce the release of Mes 0.7, representing 32
-commits over 4 weeks. Mescc now behaves more like a regular C
-compiler: supporting -E, -c, -o options and with a more complete set
-of header files [stubs]; enough to work on compiling tinycc's tcc.c
-albeit a somewhat modified version[8].
-
-* About
-
- Mes aims to create full source bootstrapping for GuixSD: an
- entirely source-based bootstrap path. The target is to [have
- GuixSD] boostrap from a minimal, easily inspectable binary --that
- should be readable as source-- into something close to R6RS
- Scheme.
-
- It currently consists of a mutual self-hosting [close to Guile-]
- Scheme interpreter prototype in C and a Nyacc-based C compiler in
- [Guile] Scheme.
-
- The Scheme interpreter prototype (mes.c) has a Garbage Collector,
- a library of loadable Scheme modules-- notably Dominique Boucher's
- LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt
- Wette's Nyacc[3] Guile's PEG[4] --and test suite just barely
- enough to support a simple REPL (repl.mes) and simple C-compiler
- (mescc.mes) that can produce the second initial ELF binary from
- binary from mes.c, in only about 2h30'.

-Subject: on bootstrapping: 2nd status report on Mes
-Date: Sun, 25 Sep 2016 13:52:11 +0200
-
-Hi!
-
-In June I announced[0] Mes as a project that seeks to reduce the size of/
-dependency on bootstrap binaries, esp. for a system like GuixSD
-
-The strategy was to create a minimal trusted binary (prototyped in C but
-eventually to be hand-crafted in assembly/hex) that interpets a minimal
-LISP. Then using this minimal but already convenient LISP, extend it
-into Scheme and write a tiny C compiler/linker.
-
-Last time I had a minimal LISP-1.5-resembling interpreter in 900 lines
-of C that could interpret itself and an extension layer written in LISP
-providing a minimal Scheme environment. I was stuck on adding macros in
-LISP and had a broken macro implentation in C that I wanted to remove.
-Also I hoped to greatly reduce the size of the C part.
-
-New status[1]
-
- * Provide Scheme primitives directly in 1400 lines of C
- * Remove LISP-1.5 staging
- * closures clue-bat, fixing bugs in begin, lambda, lexical
- scoping etc. ... learned a lot!
- * quasiquote, unquote, unquote-splicing (in C, too slow in Scheme)
- * define-macro (in C)
- * define-syntax, syntax-rules (in Scheme, using define-macro)
- * all primitives needed to run LALR (strings, vectors, records,
- some srfi bits; mostly in Scheme)
- * test suite with 97 tests that run with Mes and also with Guile
- * minimal and partial ANSI C parser for hello world
- * minimal and simplistic 32 bit elf c-ast->elf generator
-
- Mes can now create a running 32-bit elf binary from this hello
- world C source with a simplistic for loop
-
- int main ()
- {
- int i;
- puts ("Hi Mes!\n");
- for (i = 0; i < 4; ++i)
- puts (" Hello, world!\n");
- return 1;
- }
-
- It takes Mes 1'20" to compile this program, Guile takes 0.5 seconds.
-
- * cannot get psyntax.pp hooked-up or running
- * do not understand syntax stuff [well enough] to implement in C
- -> no let-syntax, no MATCH
- -> no syntax-case, no PEG parser
-
-In theory the bootstrapping problem I set out to solve seems to be
-cracked. The remaining problem is reduced to `just work':
-implementing a minimal C compiler in Scheme. Questions here: I'm not
-convinced yet that this is a meaningful project...aaand I really not
-want to tackle this without having MATCH, which Mes does not have yet.
-
-Of the possible directions that I see
-
- 0 write the C compiler in Scheme without match
- 1 rewrite match without let-syntax
- 2 grok+write let-syntax/syntax-case using define-macro, some bits in C
- 3 run and hook-up psyntax.pp...BUT that would probably require:
- 4 address performance problem, possibly by
- 5 rewrite Mes into a VM-based solution
-
-none I find really attractive. Option 5, a VM is proven to work but
-that's quite a change of direction. Looking at other VM-based projects
-(e.g. GNU Epsilon[2]) I fear that this must result in a much larger code
-base in C, throwing out the minimal trusted binary idea. The other
-puzzles and work 0, 2 or 3 still need to be done.
-
-However, diving into syntax-macro or eval work (2 or 3) most probably
-needs the performance issue addressed. And if it turns out that a big
-VM solution is needed, that may still invalidate this project after
-having done even more work.
-
-Help! :-) Ideas?

-Jan

-* General Information
-** Do you agree to follow GNU policies?
-
-Yes, of course.
-
-** Package name and version:
-
-Mes 0.16
-
-** Author Full Name <Email>:
-
-Jan (janneke) Nieuwenhuizen <janneke@gnu.org>
-
-** URL to package home page (if any): https://gitlab.com/janneke/mes
-
-I'm happy to move to savannah when Mes becomes a GNU package.
-
-** URL to source tarball:
-
-https://gitlab.com/janneke/mes/-/archive/v0.16/mes-0.16.tar.gz
-
-or: git clone https://gitlab.com/janneke/mes
-
-** Brief description of the package:
-
-Mes aims to help create full source bootstrapping for GuixSD as part of
-the bootstrappable builds effort (See https://bootstrappable.org/).
-
-It currently consists of a mutual self-hosting Scheme interpreter
-prototype written in C and a Nyacc-based C compiler written in Scheme.
-This C prototype is being simplified to be transpiled by M2-Planet.
-
-Mes+MesCC can compile an only lighty patched TinyCC 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-4.1.0.
-
-* Code
-** Dependencies:
-
-Mes can be built as a regular package, or as part of the full source
-(currently: reduced binary seed) bootstrap process.
-
-*** Regular build
-
- - https://github.com/mescc-tools, 0.5 is known to work.
- - https://savannah.gnu.org/projects/nyacc, 0.80.42 is known to work.
- - GNU Gcc, 4.9.3 is known to work.
- - GNU Guile, version 2.0.12 or is know to work.
- - SH, /bin/sh, GNU Bash 4.3 is known to work.
- - GNU coreutils
- - sed, GNU sed 4.2 is known to work.
- - git, 2.10 is known to work.
- - Perl, 5.22 is known to work.
-
-*** Bootstrap build
-
- - https://github.com/oriansj/mescc-tools, 0.5 is known to work.
- - https://savannah.gnu.org/projects/nyacc, 0.80.42 is known to work.
- - https://gitlab.com/janneke/mes-seed, 0.16 is known to work.
-
-** Configuration, building, installation:
-
-*** Guix build, install
-
- guix build mes, guix package --install mes
-
-*** Regular build
-
- ./configure; make; make check; make install
-
-*** Bootstrap build
-
- <set env vars>
- sh build.sh
- sh check.sh
- sh install.sh
-
-** Documentation:
-
-Mes does not yet have any documentation other than AUTHORS, HACKING,
-INSTALL, NEWS, README. When it does, it will be in Texinfo: I live in
-Emacs. I have initiated the GNU LilyPond documentation and website,
-which are written in texinfo.
-
-** Internationalization:
-
-Mes does not have Internationalization. As it's an early bootstrap
-package, it's unsure if it will ever get that. I do have experience
-with adding Internationalization to GNU LilyPond.
-
-** Accessibility:
-
-None.
-
-** Security:
-
-Mes will be used as a critical link in our GNU bootstrapping chain.
-It is essential for Mes to get a proper review before it is put in
-place.
-
-* Licensing:
-
-GNU GPL 3, or later.
-
-* Similar free software projects:
-
-There are similarities with GNU Guile and to a lesser extent also with
-MIT/GNU Scheme and SCM; in fact Mes' scheme tries to be compatible with
-Guile Scheme. GNU Guile is about 30x faster than Mes.
-
-The main difference is that mes.c is ~5,000LOC of very simple C and can
-can be bootstrapped almost entirely from source, without any binary
-seed. Currently, it needs a ~1MB ASSCI seed.
-
-Guile is ~100,000LOC of full-blown C, not counting its dependencies
-such as libgc.
-
-Another difference with regular Scheme implementations, is that Mes does
-not strive for RXRS compliance, instead it strives for minimalism and
-Guile compatibility.
-
-If in doubt, please contact the GuixSD or Guile maintainers.
-
-* Any other information, comments, or questions:
-
-I am an original author of GNU LilyPond and current GuixSD developer. I
-have regular discussions about Mes and GuixSD with GuixSD and Guile
-maintainers.
-
-Mes currently targets only x86-linux, I would like some help to look at
-other architectures and esp. at targeting the Hurd.

-Subject: wip-bootstrap updated
-
-I've updated the wip-bootstrap branch[0] for Mes[1] 0.13. It has new
-mes-boot and tcc-boot packages. mes-boot is a bootstrap version of
-Mes; it only depends on mescc-tools and a previously compiled mes.M1
-seed. Likewise, tcc-boot depends on a precompiled tcc-seed. Also,
-tcc-boot uses a heavily patched version of the tcc sources.
-
-Mes 0.13 is the first release that can bootstrap a fairly functional
-tcc-boot. This bootstrapped tcc passes 67/68 C tests that were created
-for MesCC. It can compile a version if itself where float, long long
-and bitfield are patched out...but linking fails. This amazing
-compiler can now be played with by doing something like
-
---8<---------------cut here---------------start------------->8---
-git checkout wip-bootstrap
-make
-./pre-inst-env guix build tcc-boot # may take ~2h
-./pre-inst-env guix environment --ad-hoc tcc-boot
-mes-tcc --help #duck and run
---8<---------------cut here---------------end--------------->8---
-
-The next big effort will be to make this mes-tcc fully functional and
-integrate this with GuixSD. To give you a taste of that,
-here's latest bug I'm currently looking at (pretty printed comments
-are only added when Guile runs MesCC, the problem is in LEA)

-
-We also need to remove some shortcuts that we took, most notably:
-mes-seed[3]. This seed consists of 1MB of M1 code. mes.M1 is
-produced by compiling mes.c using MesCC, the C compiler written in
-(Guile) Scheme that comes with Mes. Although that's really terrible,
-it's probably a big step forward: currently GuixSD uses ~250MB of
-binary seed: the bootstrap binaries.
-
-The plan is to replace the mes.M1 seed with mes.M2 and compile this
-new mes.M2 seed using the brand new M2-Planet[2]. M2 is basically
-simple C with structs, without preprocessor. This will reduce the
-seed size by a factor of 10 while making it much more readable.

+Subject: on bootstrapping: introducing Mes
+Date: Sun, 19 Jun 2016 13:08:02 +0200
+
+Hi,
+
+I have a minimal LISP-1.5-resembling interpreter in C that now can
+also interpret itself
+
+ https://gitlab.com/janneke/mes
+
+It was inspired by the seemingly often ignored bootstrapping question
+made so painfully visible by GuixSD and by OriansJ with their self
+hosting hex assembler project.
+
+As a next step after a hex assembler I was thinking of getting Scheme up
+and running and use that to create a tiny C compiler, probably using
+PEG. For that I think we need define-syntax, which I had a peek at and
+still scares the all-sorts-of-things out of me :-)
+
+I searched for minimal Lisp/Scheme to get that going and found an
+article called the Maxwell Equations of Software 1) with a pointer to
+the 1962 LISP 1.5 paper by John McCarthy 2).
+
+First I `implemented' Mes/LISP-1.5: the bottom half of page 13 and the
+necessary helper procedures defined on pages 8-12 using Guile, removing
+all but the primitives needed to run LISP-1.5/Mes (I think): car, cdr,
+cond, cons, define, eq?, '()/nil, null?, pair? and quote. I cheated
+with read, and with display and newline for debugging.
+
+Then I translated the program into C and got rid of read by using
+getchar/ungetchar.
+
+It's been great fun and now I'm kind of stuck a bit at the point of
+implementing macros. I have a simplistic version in C but want to
+remove that again --I like the idea of having the absolute minimal LISP
+interpreter in C-- and only introduce macros after having bootstrapped
+into the LISP/Mes domain.

+Subject: Mes 0.10 released
+
+I am pleased to announce the release of Mes 0.10, representing 82
+commits over 6 weeks. Mescc now compiles a bootstrappable-modified
+TinyCC into a mes-tcc that in turn can successfully compile a trivial
+C program.
+
+* About
+
+ Mes[0] aims to create full source bootstrapping for GuixSD[1] as
+ part of the bootstrappable builds[2] project.
+
+ It currently consists of a mutual self-hosting [close to Guile-]
+ Scheme interpreter prototype in C and a Nyacc-based C compiler in
+ [Guile] Scheme. This C prototype will be rewritten in stage0[3]
+ M1 assembly (or possibly stage2 slow-LISP, or ...).
+
+ The Scheme interpreter prototype (mes.c) has a Garbage Collector,
+ a library of loadable Scheme modules-- notably Dominique Boucher's
+ LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt
+ Wette's Nyacc[6], Guile's PEG[7] --and test suite just barely
+ enough to support a simple REPL (repl.mes) and simple C-compiler
+ (mescc.mes).
+
+ The simple C compiler can compile a modified TinyCC[8] that is
+ starting to work! A gcc-compiled tcc is known[9] to compile GCC.
+
+ 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 ~300 byte self-hosting
+ hex assembler.

+I am pleased to announce the release of Mes 0.15, representing 45

+
+As of 0.14, Mes+MesCC compiles a self-hosting TinyCC. Using the 0.15
+Mes C library, this TinyCC can build the GNU tools triplet:
+binutils-2.14, gcc-2.95.3, glibc-2.2.5.
+
+This means that we can build a GNU toolchain that depends only on a
+critical 1MB ASCII M1 seed. GuixSD currently uses a ~250MB binary
+seed to build gcc.
+
+Next targets are: upstream the Mes bootstrap to GuixSD, build a
+Gcc-4.7 and Glibc-2.23, bootstrap utilities like bison, flex, grep,
+sed..., replace GuixSD's bootstrap for x86 and reduce the 1MB ASCII M1
+seed to ~5000 LOC/~100KB of M2 source, which is a restricted subset of
+C.

+Subject: Mes 0.16 released
+
+I am pleased to announce the release of Mes 0.16, representing 27
+commits over 2 weeks.
+
+A most annoying ELF header bug was fixed that suddenly had all Mes
+binaries segfault before entering `_start' on Linux 4.17 and later.
+
+We now have binutils-2.20.1 and gcc-4.1.0, both compiled with
+gcc-2.95.3 and glibc-2.2.5.
+
+This reduced-binary-seed bootstrap still depends on these bootstrap
+binaries: BOOTSTRAP-GUILE, flex, bash, bzip2, coreutils, diffutils,
+gawk, grep, gzip, make, sed, tar, on the small binary seeds:
+tinycc-seed, mescc-seed and on the mes.M1 ASCII seed.
+
+Next targets:
+
+ - build a Gcc 4.7 and Glibc 2.23
+ - upstream the x86 Mes bootstrap to GuixSD
+ - reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
+ - revive Gash: a posix shell for Guile to reduce the bootstrap binary
+ dependencies
+ - and/or otherwise reduce the bootstrap binary dependencies
+
+Packages are available from Guix's wip-bootstrap branch.
+
+* About
+
+Mes[0] aims to help create full source bootstrapping for GuixSD[1] as
+part of the bootstrappable builds[2] effort.
+
+It currently consists of a mutual self-hosting Scheme interpreter
+prototype written in C and a Nyacc-based C compiler written in Scheme.
+This C prototype is being simplified[3] to be transpiled by M2-Planet[4].
+
+The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
+library of loadable Scheme modules-- notably Dominique Boucher's LALR[5],
+Pre-R6RS portable syntax-case[6] with R7RS ellipsis, Matt Wette's Nyacc[7],
+Guile's PEG[8] --and test suite just barely enough to support a simple
+REPL and simple C-compiler: MesCC.
+
+Mes+MesCC can compile an only lighty 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-4.1.0.
+
+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 https://gitlab.com/janneke/mes
+
+ wget https://gitlab.com/janneke/mes/-/archive/v0.16/mes-0.16.tar.gz
+
+Mes runs from the source tree and can also be built, packaged and
+installed in Guix[SD] by the usual
+
+ guix package -f guix.scm
+
+* Get informed, get involved
+
+ Join #bootstrappable on irc.freenode.net.
+
+* Changes in 0.16 since 0.15
+ ** Core
+ *** Support building with tcc, including Mes Lib C in-line assembly.
+ *** core:execl now supports 1000 arguments.
+ ** MesCC
+ *** Mes Lib C now bootstraps glibc-2.2.5, binutils-2.20.1, gcc-4.1.0.
+ *** MesCC binaries now run on Linux 4.17 too, i.e. survive Linus' new `sane mmap limits.'
+ *** MesCC now runs with mescc-tools 0.5 (no = in long options).
+ **** 3 new C test
+ 88-strrchrc, 97-fopen.c, 98-fopen.c.
+ ** Noteworthy bug fixes
+ *** strrchr now stops when it reaches start of string.
+ *** fopen now return 0 upon failure. Supports binutils' hack: fd=-2 means `cached'.
+ *** vfprintf, vsprintf now support precision and width on integers strings better.
+ *** fread now produces ungetc'd chars too.
+ *** memcmp now supports comparing 0 bytes, supporting binutils.
+
+ *** The unused ELF header data section, identical to the text section, has been removed.

+Subject: on bootstrapping: first Mes 0.3 released
+
+I am pleased to announce the first release of Mes: 0.3, representing
+152 commits over 3 months since the second status report[1].
+
+* About
+
+ Mes aims to create an entirely source-based bootstrapping path. The
+ target is to [have GuixSD] boostrap from a minimal, easily inspectable
+ binary --that should be readable as source-- into something close to
+ R6RS Scheme.
+
+ As bootstrapping is presumably easiest and probably most fun with
+ Scheme, the next step for Mes is mescc: a C compiler/linker to
+ boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.
+
+ It currently has an interpreter written in C (mes) with Garbage
+ Collector (Jam Scraper), a library of loadable Scheme modules with
+ test suite just barely enough to support a simple REPL (repl.mes)
+ and a proof-of-concept c-compiler (mescc.mes) that produces an elf
+ from the simplest of C files.

+
+Mes runs from the source tree and can also be built, packaged and
+installed in Guix[SD] by the usual
+
+ guix package -f guix.scm
+
+
+* Changes in 0.3 since 0.2
+ ** Core
+ *** Number-based rather than pointer-based cells.
+ *** Garbage collector aka Jam scraper.
+ A variant on SICP's stop and copy Garbage Collector (Jam Scraper?)
+ algorithm has been implemented.
+ *** The reader has been moved to Scheme.
+ ** Language
+ *** Simple loadable modules.
+ *** Srfi-9 and match use handwritten syntax-rules (mes-use-module (mes syntax)).
+ *** Optional syntax-case using psyntax (mes-use-module (mes psyntax)).
+ ** Noteworthy bug fixes
+ *** Srfi-0 has been fixed.
+
+* Changes in 0.2 since 0.1
+ ** Core
+ *** Names of symbols and strings are list of characters [WAS: c-string].
+ *** Sc-expand from pre-R6RS's psyntax has been integrated.
+ *** Undefined variable error now shows the name of the undefined variable.
+ *** There is now only one SCM type for builtin functions.
+ *** Macro expansion has been cleaned-up.
+ ** Language
+ *** Mes now provides a subset of R6RS.
+ *** Mes now provides syntax-case.
+ *** Mes now provides `load'.
+ ** Noteworthy bug fixes
+ *** Using values as second parameter of builtin function yields first value.
+ *** Quoted internals (e.g. 'if 'lambda) are now symbols.
+ *** Syntax error now exits.
+ *** Make+Bash voodoo has been replaced by build-aux/mes-snarf.scm.
+ *** Apply now accepts multiple list arguments.
+ *** Apply of character, inernal, number, string is an error.
+ *** Quasisyntax reading
+
+* Changes in 0.1 (since progress report #2)
+ ** Core
+ *** expand_macro is now a separate function.
+ *** A smaller core can now compiled using BOOT=1.
+ The smaller core does not provide define, define-macro, or quasiquote;
+ these are provided from a Scheme version of implemented eval/apply.
+ ** Language
+ *** Mes now provides a subset of R5RS.
+ *** Mes now provides let-syntax.
+ *** Mes now provides match.
+ *** Mes now provides quasisyntax, unsyntax and unsyntax-splicing.
+ ** User interface
+ *** Mes now provides a REPL, run:
+ scripts/repl.mes
+ *** Mes compiler can be run as a script:
+ scripts/mescc.mes doc/examples/main.c
+ *** Macro expansion can be inspected in the REPL, e.g.:
+ ,expand (and 0 1)
+ ** Noteworthy bug fixes
+ *** Performance: scripts/mescc.mes now takes 2s to compile main.c (was 1'20").
+ *** Symbols are now truly unique.
+ * '(), #t, #f are no longer symbols.

+Subject: Mes 0.4 released
+
+I am pleased to announce the release of Mes 0.4, representing 115
+commits over barely two weeks. It now runs Nyacc and PEG and has much
+reduced core.
+
+* About
+
+ Mes aims to create an entirely source-based bootstrapping path. The
+ target is to [have GuixSD] boostrap from a minimal, easily inspectable

+Mes runs from the source tree and can also be built, packaged and
+installed in Guix[SD] by the usual
+
+ guix package -f guix.scm
+
+* Changes in 0.4 since 0.3
+ ** Core
+ *** Improved performance.
+ Macros are now memoized; after expansion and before eval'ing the
+ expanded form, their input s-expression is replaced by the expansion.
+ This yields a nice performance improvement which finally allowed
+ moving all non-essential bits from the C-core into Scheme...including
+ the reader. The Scheme reader is much, much slower than the previous
+ C version, making Mes--again-- feel slow. Think of that as a feature.
+ *** Bootstrap with minimal reader in C.
+ The C-reader needs only support reading of words and lists
+ (s-expressions), line-comments to read the initial Scheme reader which
+ then takes over and handles reading of quoting, characters, strings,
+ block-comments.
+ *** Reduced size.
+ Total C size: ~1500LOC. The main Mes evaluator is now ~1000LOC
+ including cell creation and garbage collector. This code is able to
+ execute a Scheme program that has been loaded into memory. Another
+ ~500LOC is spent to load a minimal Scheme program and to dump it, to
+ provide a small posix interface, math functions and do some error
+ reporting.
+ *** Programs can be dumped and loaded using --dump and --load.
+ ** Language
+ *** Minimal syntactic exception support for Nyacc.
+ *** Minimal syntactic fluids support for Nyacc.
+ *** Keywords are now supported.
+ *** Cond now supports =>.
+ *** Guile's optargs: lambda* and define* are now supported.
+ *** #;-comments are now supported.
+ *** Non-nested #| |#-comments are now supported.
+ *** Quasisyntax is now supported.
+ *** R7RS syntax-rules with custom ellipsis, with-ellipsis are now supported.
+ *** 9 new [partial] modules
+ (mes fluids), (mes nyacc), (mes optargs), (mes pmatch), (mes peg),
+ (srfi srfi-13), (srfi srfi-9-psyntax), (srfi srfi-26), (srfi srfi-43),
+ (rnrs arithmetic bitwise), (sxml xpath)
+ *** 36 new functions
+ 1+, 1-, abs, and=>, append-reverse, ash, char<=?, char<?, char>=?,
+ char>?, even?, filter, delete, delq, vector-copy, fold, fold-right,
+ getenv, iota, keyword->symbol list-head, list-tail, negative?, odd?,
+ positive?, remove!, remove, string->number, string-copy,
+ string-prefix?, string=, string=?, symbol->keyword symbol-append,
+ symbol-prefix?, unless, write, zero?.
+ ** Noteworthy bug fixes
+ *** Macros are now memoized.
+ *** An error is reported when using a wrong number of arguments with a call.
+ *** Cond now evaluates its test clauses only once.
+ *** Append can also handle one argument.
+ *** For-each now supports 2 list arguments.
+ *** Map now supports 3 list arguments.
+ *** Backslash in string is supported.
+ *** Closure is not a pair.
+ *** All standard characters are supported.
+ *** Mescc now also runs in Guile.

+Subject: Mes 0.8 released
+
+I am pleased to announce the release of Mes 0.8, representing 34
+commits over 3 weeks. Mescc now produces object files in the hex2
+ascii output format compatible with the stage0 linker.
+
+Special thanks to Jeremiah Orians for support with MESCC_Tools and
+hex2, more goodness to follow soon!
+
+* About
+
+ Mes aims to create full source bootstrapping for GuixSD: an

+ Scheme.
+
+ It currently consists of a mutual self-hosting [close to Guile-]
+ Scheme interpreter prototype in C and a Nyacc-based C compiler in
+ [Guile] Scheme.
+
+ The Scheme interpreter prototype (mes.c) has a Garbage Collector,

+Subject: Mes 0.9 released
+
+I am pleased to announce the release of Mes 0.9, representing 107
+commits over 5 weeks. Mescc now compiles to a surprisingly readable

+ [Guile] Scheme. This C prototype will be rewritten in stage0[3]
+ M1 assembly (or possibly stage2 slow-LISP, or ...).
+
+ The Scheme interpreter prototype (mes.c) has a Garbage Collector,
+ a library of loadable Scheme modules-- notably Dominique Boucher's
+ LALR[4], Pre-R6RS portable syntax-case[5] with R7RS ellipsis, Matt

+Subject: on bootstrapping: 2nd status report on Mes
+Date: Sun, 25 Sep 2016 13:52:11 +0200
+
+Hi!
+
+In June I announced[0] Mes as a project that seeks to reduce the size of/
+dependency on bootstrap binaries, esp. for a system like GuixSD
+
+The strategy was to create a minimal trusted binary (prototyped in C but
+eventually to be hand-crafted in assembly/hex) that interpets a minimal
+LISP. Then using this minimal but already convenient LISP, extend it
+into Scheme and write a tiny C compiler/linker.
+
+Last time I had a minimal LISP-1.5-resembling interpreter in 900 lines
+of C that could interpret itself and an extension layer written in LISP
+providing a minimal Scheme environment. I was stuck on adding macros in
+LISP and had a broken macro implentation in C that I wanted to remove.
+Also I hoped to greatly reduce the size of the C part.
+
+New status[1]
+
+ * Provide Scheme primitives directly in 1400 lines of C
+ * Remove LISP-1.5 staging
+ * closures clue-bat, fixing bugs in begin, lambda, lexical
+ scoping etc. ... learned a lot!
+ * quasiquote, unquote, unquote-splicing (in C, too slow in Scheme)
+ * define-macro (in C)
+ * define-syntax, syntax-rules (in Scheme, using define-macro)
+ * all primitives needed to run LALR (strings, vectors, records,
+ some srfi bits; mostly in Scheme)
+ * test suite with 97 tests that run with Mes and also with Guile
+ * minimal and partial ANSI C parser for hello world
+ * minimal and simplistic 32 bit elf c-ast->elf generator
+
+ Mes can now create a running 32-bit elf binary from this hello
+ world C source with a simplistic for loop
+
+ int main ()
+ {
+ int i;
+ puts ("Hi Mes!\n");
+ for (i = 0; i < 4; ++i)
+ puts (" Hello, world!\n");
+ return 1;
+ }
+
+ It takes Mes 1'20" to compile this program, Guile takes 0.5 seconds.
+
+ * cannot get psyntax.pp hooked-up or running
+ * do not understand syntax stuff [well enough] to implement in C
+ -> no let-syntax, no MATCH
+ -> no syntax-case, no PEG parser
+
+In theory the bootstrapping problem I set out to solve seems to be
+cracked. The remaining problem is reduced to `just work':
+implementing a minimal C compiler in Scheme. Questions here: I'm not
+convinced yet that this is a meaningful project...aaand I really not
+want to tackle this without having MATCH, which Mes does not have yet.
+
+Of the possible directions that I see
+
+ 0 write the C compiler in Scheme without match
+ 1 rewrite match without let-syntax
+ 2 grok+write let-syntax/syntax-case using define-macro, some bits in C
+ 3 run and hook-up psyntax.pp...BUT that would probably require:
+ 4 address performance problem, possibly by
+ 5 rewrite Mes into a VM-based solution
+
+none I find really attractive. Option 5, a VM is proven to work but
+that's quite a change of direction. Looking at other VM-based projects
+(e.g. GNU Epsilon[2]) I fear that this must result in a much larger code
+base in C, throwing out the minimal trusted binary idea. The other
+puzzles and work 0, 2 or 3 still need to be done.
+
+However, diving into syntax-macro or eval work (2 or 3) most probably
+needs the performance issue addressed. And if it turns out that a big
+VM solution is needed, that may still invalidate this project after
+having done even more work.
+
+Help! :-) Ideas?
+
+Greetings,
+Jan

+Subject: wip-bootstrap updated
+
+I've updated the wip-bootstrap branch[0] for Mes[1] 0.13. It has new
+mes-boot and tcc-boot packages. mes-boot is a bootstrap version of
+Mes; it only depends on mescc-tools and a previously compiled mes.M1
+seed. Likewise, tcc-boot depends on a precompiled tcc-seed. Also,
+tcc-boot uses a heavily patched version of the tcc sources.
+
+Mes 0.13 is the first release that can bootstrap a fairly functional
+tcc-boot. This bootstrapped tcc passes 67/68 C tests that were created
+for MesCC. It can compile a version if itself where float, long long
+and bitfield are patched out...but linking fails. This amazing
+compiler can now be played with by doing something like
+
+--8<---------------cut here---------------start------------->8---
+git checkout wip-bootstrap
+make
+./pre-inst-env guix build tcc-boot # may take ~2h
+./pre-inst-env guix environment --ad-hoc tcc-boot
+mes-tcc --help #duck and run
+--8<---------------cut here---------------end--------------->8---
+
+The next big effort will be to make this mes-tcc fully functional and
+integrate this with GuixSD. To give you a taste of that,
+here's latest bug I'm currently looking at (pretty printed comments
+are only added when Guile runs MesCC, the problem is in LEA)
+

+
+We also need to remove some shortcuts that we took, most notably:
+mes-seed[3]. This seed consists of 1MB of M1 code. mes.M1 is
+produced by compiling mes.c using MesCC, the C compiler written in
+(Guile) Scheme that comes with Mes. Although that's really terrible,
+it's probably a big step forward: currently GuixSD uses ~250MB of
+binary seed: the bootstrap binaries.
+
+The plan is to replace the mes.M1 seed with mes.M2 and compile this
+new mes.M2 seed using the brand new M2-Planet[2]. M2 is basically
+simple C with structs, without preprocessor. This will reduce the
+seed size by a factor of 10 while making it much more readable.
+
+An excerpt of the TODO I keep in Mes' BOOTSTRAP document
+
+--8<---------------cut here---------------start------------->8---
