There are some incompatible changes here, but only to interfaces that were introduced earlier in 1.9, or interfaces which have been broken since early in 1.9. * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, as the macro changes affect the interface that is called by psyntax-generated macro definitions. * libguile/inline.h (scm_words): New function, allocates a variable number of contiguous scm_t_bits locations, with a given value in the 0th word, and 0 in the rest of the words. * libguile/macros.h: Rework interface to correspond more closely, and minimally, to the needs of memoize.c and psyntax. (SCM_ASSYNT, SCM_MACRO_TYPE_BITS, SCM_MACRO_TYPE_MASK) (SCM_F_MACRO_EXTENDED, SCM_MACROP, SCM_MACRO_TYPE) (SCM_MACRO_IS_EXTENDED, SCM_BUILTIN_MACRO_P, SCM_SYNCASE_MACRO_P) (SCM_MACRO_CODE, scm_tc16_macro): Remove CPP macros related to the representation of Scheme macros. (scm_i_make_primitive_macro): Renamed from scm_i_makbimacro. (scm_i_macro_primitive): New accessor so that memoize.c can get to the primitive syntax transformer. (scm_make_syncase_macro, scm_make_extended_syncase_macro) (scm_syncase_macro_type, scm_syncase_macro_binding): Removed these functions, replaced by make-syntax-transformer and its accessors. (scm_macro_binding): New accessor, the same as what scm_syncase_macro_binding was. * libguile/macros.c: All representation details of syntax transformers are private to this file now. (macro_print): Print macros as #<syntax-transformer ...>, or #<primitive-syntax-transformer ...> if psyntax has not attached a transformer of its own. (scm_i_make_primitive_macro): Represent macros as 5-word smobs. (scm_make_syntax_transformer): New constructor for syntax transformers (macros), exported to scheme. Takes a name, and looks it up in the current module to determine the previous primitive transformer, if any. (scm_macro_type): Instead of returning 'builtin-macro!, etc, return the type as set by psyntax, or #f if it's a primitive. (scm_macro_name): Return the stored macro name. (scm_macro_transformer): Return the psyntax-set syntax transformer. Hacky, but should help introspection somewhat. * libguile/memoize.c (memoize_env_ref_transformer): Use the new scm_i_macro_primitive, and adapt to other macro API changes. * module/ice-9/psyntax.scm (put-global-definition-hook) (get-global-definition-hook, chi-install-global): Call (and generate calls to) the new macro constructors and accessors. * module/ice-9/psyntax-pp.scm: Doubly regenerated. * module/ice-9/debugging/traps.scm (trap-here): Comment out this definition and export, while it's not working. |
