* libguile/macros.c (macro_print): Show syntax-case bindings, if present.
(macro_mark): Mark the extra two words if they're there.
(scm_make_syncase_macro, scm_make_extended_syncase_macro): OK! A new
take at the "how do we represent syncase macros in Guile" problem.
Whereas we need a disjoint type, but would like it to be compatible
with old predicates (e.g. `macro?'), and need to be able to extend
existing syntax definitions (e.g. `cond'), let's add a bit to macros to
indicate whether they have syncase macro bindings or not, and a fourth
macro type for native syncase macros.
(scm_macro_type): Return 'syntax-case for native syntax-case macros.
Note that other macro types may have syntax-case bindings.
(scm_macro_name): Return #f if the transformer is not a procedure.
(scm_syncase_macro_type, scm_syncase_macro_binding): New accessors for
the syncase macro bindings.
* libguile/macros.h: Add API for syncase macros.
* module/ice-9/boot-9.scm (module-define-keyword!): Adapt to use syncase
macros, though they are not yet used. Reorder other syncase API.
* module/ice-9/psyntax.scm (chi-expr): Fix syntax-violation invocation.
This directory contains various bits of Guile Scheme code.
Most of these are packaged as modules, with foo.scm implementing
the module `(ice-9 foo)'.
The non-module files are:
boot-9.scm -- loaded on guile startup
implements module system + lots of other stuff
arrays.scm -- loaded by boot-9.scm
networking.scm -- loaded by boot-9.scm
posix.scm -- loaded by boot-9.scm
r4rs.scm -- loaded by boot-9.scm
