[ANN] nyacc 1.00.0 released

[ANN] nyacc 1.00.0 released

[Matt Wette]

Hi All,

I am finally pushing out a 1.0 release of nyacc.

NYACC, for Not Yet Another Compiler Compiler, is set of guile modules for
generating parsers and lexical analyzers.  It also provides sample parsers
and pretty-printers using SXML trees as an intermediate representation.

It provides a decent C parser and a `FFI Helper' tool to help create
Guile Scheme bindings for C-based libraries.

It provides (partially implemented) compilers based on above mentioned
parsers to allow execution with Guile as extension languages.

Here are updates from V0.99.3:
     * Makefiles now use "$(MAKE)" instead of "make"
     * changed order of udict, ddict arguments to canize-enum-def-list
     * removed hacks from eval-cpp-expr prev used by canize-enum-def-list
     * cleaned up cxeval failures

NYACC maturity is production/stable level.

NYACC is free software; the full source distribution is available through

* the tarball repository:
     https://download.savannah.gnu.org/releases/nyacc/

* the git repository:
     git://git.savannah.nongnu.org/nyacc.git

Wow, congrats!  An amazing piece of work.

Trying to update the Nyacc package in Guix, I found that Mes does not
build with 1.00.0.

When FOO is not defined, this

--8<---------------cut here---------------start------------->8---
#if FOO
#endif
--8<---------------cut here---------------end--------------->8---

produces a backtrace.

To reproduce, run

--8<---------------cut here---------------start------------->8---
guile -c '(use-modules (nyacc lang c99 parser)) (display (with-input-from-string "#if FOO\n#endif" parse-c99))'
--8<---------------cut here---------------end--------------->8---

With 0.99.0, this gives (trans-unit), with 1.00.0 I get

--8<---------------cut here---------------start------------->8---

I found this.  Will appear fixed in 1.00.1 coming soon.
