* libguile/programs.h (SCM_F_PROGRAM_IS_PRIMITIVE_GENERIC)

  accessor, for when we switch primitives to be implemented using VM
  trampolines.

31a26df2cc program-meta procedures get their program's objtable
* libguile/programs.c (scm_program_meta): Give the program meta
  procedure the same object table as the main procedure. Will allow for
  easier hand-crafting of meta programs. Of course when compiling a
  metadata procedure from Scheme, one still wants to avoid preallocating
  the heap objects needed by the metadata...

9c246c0383 remove unused snarf macros
* libguile/snarf.h (SCM_DEFINE1, SCM_PRIMITIVE_GENERIC_1, SCM_PROC1)
  (SCM_GPROC1): Remove, as these deal in the removed typed subr
  constructors.

* libguile/tags.h (scm_tcs_subrs): Remove this. Use scm_tc7_gsubr
  instead, though hopefully that will go too, soon.

9fdf9fd3ea move subr implementation details to gsubr.[ch]
* libguile/procs.h: Move subr macros to gsubr.h.
* libguile/procs.c (scm_c_make_subr, scm_c_make_subr_with_generic)
  (scm_c_define_subr, scm_c_define_subr_with_generic): Remove these,
  because they deal in subr types, and now there is only one subr type.
  The body of this code is now in gsubr.c.

* libguile/deprecated.h (scm_subr_p): Remove from procs.[ch] and define
  as a deprecated macro. Only used internally, but who knows who's out
  there.

* libguile/goops.c (scm_generic_capability_p)
  (scm_enable_primitive_generic_x, scm_set_primitive_generic_x)
  (scm_primitive_generic_generic): Use the new SCM_PRIMITIVE_GENERIC_P
  macro instead of calling scm_subr_p.

* libguile/gsubr.h (SCM_PRIMITIVE_P, SCM_PRIMITIVE_GENERIC_P): New
  macros, to replace scm_subr_p and hacky checking for generic
  capability.
  (SCM_SUBR_META_INFO, SCM_SUBR_NAME, SCM_SUBRF, SCM_SUBR_PROPS)
  (SCM_SUBR_GENERIC, SCM_SET_SUBR_GENERIC, SCM_SET_SUBR_GENERIC_LOC)
  (SCM_SUBR_ARITY_TO_TYPE): Moved here from procs.h.

* libguile/gsubr.c (create_gsubr): Inline the
  scm_c_make_subr definition here, and work for generics too. Removed a
  scm_remember_upto_here_1 that was added earlier in the year when
  meta_info was not being traced by the GC. Adapt callers.

e809758a7e clean up macros.[ch]
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.

bab9804661 remove mmacros, SCM_SYNTAX snarf macro
* libguile/snarf.h (SCM_SYNTAX): Remove snarf macro, users can't define
  primitive syntax any more.

* libguile/memoize.c (SCM_SYNTAX): Define locally, and just call
  scm_i_makbimacro as there's no difference between that and
  scm_makmmacro. Alter invocations to suit.

* libguile/macros.h:
* libguile/macros.c (scm_i_makmmacro): Remove; users can't define
  primitive syntax any more. Use define-syntax instead.
  (scm_make_synt): Remove, this was only used by the SCM_SYNTAX snarf
  macro.
  (scm_i_makbimacro): Change prototype of this internal function to make
  the gsubr on behalf of the caller.
  (macro_print, scm_macro_type): Remove cases for mmacros.

9f09b127d4 remove scm_makacro and scm_makmacro
* libguile/macros.h:
* libguile/macros.c (scm_makacro): Remove this function for making
  "acros", as it is unused and won't work with the compiler.
  (scm_makmacro): Remove this deprecated function for making
  non-memoizing macros, as they won't work with the compiler.
  (macro_print, scm_macro_type): Remove a couple of cases for macros
  that can't be created any more.

* libguile/deprecated.c (scm_make_subr, scm_make_subr_with_generic)
  (scm_make_subr_opt): Remove these functions that were deprecated in
  2003, as they explicitly reference subr types.

e773b1e6ce dynamic-func returns foreign objects, not bignums
* libguile/dynl.c (scm_dynamic_func, scm_dynamic_call)
  (scm_dynamic_args_call): Change the representation of dynamic
  functions to be foreign objects. Shouldn't affect any users, as people
  should be treating the return value of dynamic-func as an opaque
  object.

e2c2a6994d add foreign value wrapper
* libguile/foreign.h:
* libguile/foreign.c: New files, implementing simple wrappers around
  foreign values, such as those that one might link in dynamically from
  a library.

* libguile/tags.h (scm_tc7_foreign): Take a tc7 for foreign values.

* libguile.h:
* libguile/init.c: Add foreign.h to headers and init.

* libguile/print.c (iprin1): Add printer for foreign values.

* libguile/gc.c (scm_i_tag_name): Case for foreign values.
* libguile/goops.c (scm_class_of, create_standard_classes): Add a class
  for foreign values.

* libguile/evalext.c (scm_self_evaluating_p): Add case for foreign
  values.

* libguile/Makefile.am: Add foreign.[ch] to the build.

a5bbb22e83 rename goto/args and friends to tail-call, tail-apply, etc
* libguile/vm-i-system.c (tail-call, tail-call/nargs, tail-apply)
  (tail-call/cc): Rename these back to tail-* from goto/*. We should
  reserve the rename-then-goto name for when you actually do a rename
  and goto, not when you shuffle the stack.

* doc/ref/vm.texi:
* module/language/glil/decompile-assembly.scm:
* module/language/tree-il/compile-glil.scm:
* test-suite/tests/tree-il.test: Adapt all callers and documentation.

  bug iterating over indices of array. Thanks to Tristan Colgate for the
  report.

* test-suite/tests/srfi-4.test: Add tests that uniform-vector->list
  works for all kinds of uniform vectors.

  scm_string_normalize_nfc, scm_string_normalize_nfd, scm_normalize_nfkc,
  scm_string_normalize_nfkd): New functions.
* test-suite/tests/strings.test: Unit tests for `string-normalize-nfc',
  `string-normalize-nfd', `string-normalize-nfkc', and
  `string-normalize-nfkd'.
* doc/ref/api-data.texi (String Comparison): Documentation for normalization
  functions.

7abb7efd31 frames.c no longer exports frame-source -- frame.scm does so already
* libguile/frames.c (scm_frame_source): No longer exported to Scheme
  via init's call to scm_init_frames; in fact just calls the Scheme
  version. Perhaps this function is on its way out, though :)

1c5e812258 clean up (system vm frames), add locals command to debugger
* libguile/frames.c (scm_init_frames): No need to bootstrap the VM here,
  it should be already bootstrapped by init.c.
  (scm_bootstrap_frames): No need to register an extension, as
  scm_init_frames is called by init.c.

* module/system/vm/frame.scm: Don't load the scm_init_frames extension,
  as the primitives from frames.c are loaded by Guile's init.
  (frame-bindings): Change to return bindings, as can be accessed by the
  binding: accessors from program.scm.
  (frame-lookup-binding): Revive and make this one work with current
  code.
  (frame-binding-set!):
  (frame-binding-ref): Use the new frame-lookup-binding. Perhaps these
  should handle boxing and unboxing, though.
  (frame-source): New accessor, returns a source object.
  (frame-call-representation): Change to return a full list, as
  truncated-print can truncate for us.
  (frame-environment, frame-object-binding, frame-object-name): Update
  not to take an address, as the address is part of the frame.
  (frame-variable-exists?, frame-variable-ref, frame-variable-set!)
  (frame-local-variables, frame-program-name, print-frame)
  (print-frame-chain-as-backtrace, frame-file, frame-line-number)
  (make-frame-chain, bootstrap-frame?, frame-number, frame-address):
  Remove these outdated functions.

* module/system/vm/debug.scm (debugger-repl): Use
  frame-call-representation, and ~@y.
  (locals): New command, prints local variables in a frame.

c5f171027d fix bug in string array implementation type mask
* libguile/strings.c (SCM_ARRAY_IMPLEMENTATION): The mask for the string
  array implementation should be 0x7f, without masking out 0x2.
  Otherwise numbers were being thought to be vectors!

* test-suite/tests/unif.test: Add test.

* libguile/vectors.c (SCM_ARRAY_IMPLEMENTATION): Only register one
  implementation, because weak vectors can be checked with the mask &
  ~2, and the functions are the same.

b521d265b1 Fix bugs reading long tokens
The commit "don't take string-write mutex in read.c:read_token", from
8b0d7b9d94, had a number of bugs. Not sure
how I missed these before.

* libguile/read.c (read_token): Remove a couple of bogus
  scm_i_string_stop_writing () calls, now that we no longer take the
  string-write mutex.
  (read_complete_token): read_token really needs a fresh buffer, which
  was not the case when we are reading long tokens and thus hit the
  overflow case. Fixes fractions.test.

b349875146 Incorrect indexing into character name list

  allocate some other symbols.

* module/ice-9/optargs.scm (parse-lambda-case): Throw to
  'keyword-argument-error in kwarg error cases.

* module/ice-9/psyntax.scm (build-lambda-case): Remove a couple
  workarounds for the old memoizer. Throw to 'wrong-number-of-args if
  the lambda-case fails to parse.

* module/ice-9/psyntax-pp.scm: Regenerated.

* test-suite/tests/optargs.test: Update expected exceptions.

820f33aaed Improved support for Unicode title case in Guile's string and character APIs.
* doc/ref/api-data.texi (Characters): Documentation for `char-titlecase'.
* doc/ref/api-i18n.texi (Character Case Mapping): Documentation for
  `char-locale-titlecase' and `string-locale-titlecase'.

* libguile/chars.c, libguile/chars.h (scm_char_titlecase, scm_c_titlecase): New
  functions.

* libguile/i18n.c, libguile/i18n.h (chr_to_case, scm_char_locale_titlecase,
  str_to_case, scm_string_locale_titlecase): New functions.
* libguile/i18n.c (scm_char_locale_downcase, scm_char_locale_upcase,
  scm_string_locale_downcase, scm_string_locale_upcase): Refactor to share code
  via chr_to_case and str_to_case, as appropriate.
* module/ice-9/i18n.scm (char-locale-title-case, string-locale-titlecase): New
  functions.

* libguile/srfi-13.c (string_titlecase_x): Use uc_totitle instead of uc_toupper.

8b0d7b9d94 don't take string-write mutex in read.c:read_token
* libguile/read.c (read_token): Don't take the string-write mutex when
  reading a token into a buffer, because it's assumed that the buffer is
  fresh (not seen by other threads), and a soft port can call a
  procedure that needs the string-write mutex.

7656f19446 rework vm tracing
* libguile/vm-engine.c (VM_NAME): Engines take the VM itself (not the
  vp), so they can pass the VM to hooks. No more hook args, we dispatch
  without them.

* libguile/vm-engine.h (RUN_HOOK): Dispatch the hook if the trace level
  is positive (instead of if the hook is there). Don't cache registers
  on return from the dispatch.

* libguile/vm.h:
* libguile/vm.c (vm_dispatch_hook): Don't bother with a dynwind; instead
  decrement the trace level when going into a hook, and if we have a
  nonlocal exit, the trace level never gets incremented again. Worse is
  better.
  (make_vm, scm_vm_trace_level, scm_set_vm_trace_level_x): New concept,
  trace level. If positive, we run the hooks, otherwise we don't. Should
  work. Removed scm_vm_trace_frame, I don't think that was the right way
  to do it.

* module/system/vm/vm.scm: Replace vm-trace-frame with vm-trace-level
  and set-vm-trace-level!; the hooks actually get the frame as an
  argument now.

* libguile/goops.h:

  Scheme's `add-method!'.

3c98a49cbd in the load path, look in library-dir before site-dir
* libguile/load.c (scm_init_load_path): Search first in Guile's
  version-specific path (the library path), *then* in the site dir. This
  should allow us to import some of Guile-lib's modules into Guile,
  perhaps customizing them with Guile-version-specific foo, without
  accidentally falling back to system-installed guile-lib in the
  sitedir. Also should reduce the number of stats by half, in the common
  case.
