|
|
|
|
- support regexp OR rewrite Nyacc without regexps

|
2017-03-29 06:05:18 +00:00

** 0.3: Garbage collector
|
|
|
|
|
** 0.2: Support psyntax

* Bugs
|
2017-04-02 15:01:29 +00:00
|
|
|
** eval_apply/gc + Nyacc bug
|
|
|
|
|
scripts/messc.mes intermittently exposes a bug in eval_apply/gc when
|
|
|
|
|
Nyacc parses mes.c-sized source. Running
|
|
|
|
|
|
|
|
|
|
MES_MAX_ARENA=<another-size> scripts/mescc.mes
|
|
|
|
|
|
|
|
|
|
may [un]cover the bug. So there is probably some eval_apply-construct
|
|
|
|
|
that Nyacc uses, possiblby indirectly via with-fluid, like (call/cc,
|
|
|
|
|
call-with-current-continuation), that breaks when GC triggers at the
|
|
|
|
|
wrong time.
|
|
|
|
|
** mescc can only compile itself, it cannot compile tcc, gcc or guile
|
|
|
|
|
** mes.mes cannot read sexps, only --dump's, mes.mes cannot --dump
|
|
|
|
|
** Bootstrap binary mes is too big and opaque to be considered source
|
|
|
|
|
68kB ELF binary which can be disassembled (objdump -d mes.mes).
|
|
|
|
|
** Psyntax is too big and opaque to be considered source
|
|
|
|
|
And needs a patched Guile-1.8 to [re]generate.
|
2017-04-01 13:06:07 +00:00
|
|
|
** test/match.test ("nyacc-simple"): hygiene problem in match
|
2017-04-02 15:01:29 +00:00
|
|
|
** Performance
|
|
|
|
|
*** mes is slow
|
|
|
|
|
*** The Scheme reader is very slow.
|
|
|
|
|
*** mescc is slow
|
|
|
|
|
**** compiling mes.c takes mescc.mes 2h30'
|
|
|
|
|
mescc.scm which runs on Guile takes 30"
|
2016-12-24 16:22:34 +00:00
|

** Fluids are a hack for Nyacc.

*** Translate C-prototype mes.c into annotated hex?
|
2017-01-22 13:16:22 +00:00
|
|
|
One idea is to use OriansJ's amazing self-hosting [[https://github.com/oriansj/stage0][stage0]] hex assembler
|
2016-10-15 09:54:24 +00:00
|
|
|
and minimal bootstrap binaries and rewrite the mes.c core to directly
|
|
|
|
|
bootstrap into Scheme.
|
|
|
|
|
|
2016-12-24 16:22:34 +00:00
|
|
|
*** Rewrite mes.c in Schemy/Sexp-C and generate annotated hex?
|
|
|
|
|
Another idea (thanks Rutger!) is to rewrite the mes.c core in a s-exp
|
2016-11-02 14:35:32 +00:00
|
|
|
C/Assembly variant and thave mescc produce the simple, annotated

|
|
|
bootstrap binary.

* OLD: Booting from LISP-1.5 into Mes
|
2016-07-22 20:12:05 +00:00
|
|
|
|
|
|
|
|
Mes started out experimenting with booting from a hex-coded minimal
|
2016-10-15 09:54:24 +00:00
|
|
|
LISP-1.5 (prototype in mes.c), into an almost-RRS Scheme.
|
2016-07-22 20:12:05 +00:00
|
|
|
|
|
|
|
|
When EOF is read, the LISP-1.5 machine calls loop2 from loop2.mes,
|
|
|
|
|
which reads the rest of stdin and takes over control. The functions
|
|
|
|
|
readenv, eval and apply-env in mes.mes introduced define, define-macro
|
|
|
|
|
quasiquote and macro expansion.
|
|
|
|
|
|
|
|
|
|
While this works, it's amazingly slow. We implemented a full reader
|
|
|
|
|
in mes.c, which makes running mes:apply-env mes:eval somewhat
|
|
|
|
|
bearable, still over 1000x slower than running mes.c.
|
|
|
|
|
|
2016-10-15 09:54:24 +00:00
|
|
|
Bootstrapping has been removed and mes.c implements enough of RRS to
|
2016-07-22 20:12:05 +00:00
|
|
|
run a macro-based define-syntax and syntax-rules.
|
|
|
|
|
|
|
|
|
|
loop.mes and mes.mes are unused and lagging behind. Probably it's not
|
|
|
|
|
worth considering this route without a VM. GNU Epsilon is taking the
|
|
|
|
|
more usual VM-route to provide multiple personas. While that sounds
|
2016-10-15 09:54:24 +00:00
|
|
|
neat, Lisp/Scheme, bootstrapping and trusted binaries are probably not
|
|
|
|
|
in scope as there is no mention of such things; only ML is mentioned
|
|
|
|
|
while Guile is used for bootstrapping.
