implement equalp in C, fix case-folding, add equal() method for keymaps -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-02-01 Ben Wing <ben@xemacs.org> * cl-extra.el: * cl-extra.el (cl-string-vector-equalp): Removed. * cl-extra.el (cl-bit-vector-vector-equalp): Removed. * cl-extra.el (cl-vector-array-equalp): Removed. * cl-extra.el (cl-hash-table-contents-equalp): Removed. * cl-extra.el (equalp): Removed. * cl-extra.el (cl-mapcar-many): Comment out the whole `equalp' implementation for the moment; remove once we're sure the C implementation works. * cl-macs.el: * cl-macs.el (equalp): Simplify the compiler-macro for `equalp' -- once it's in C, we don't need to try so hard to expand it. src/ChangeLog addition: 2010-02-01 Ben Wing <ben@xemacs.org> * abbrev.c (abbrev_match_mapper): * buffer.h (CANON_TABLE_OF): * buffer.h: * editfns.c (Fchar_equal): * minibuf.c (scmp_1): * text.c (qxestrcasecmp_i18n): * text.c (qxestrncasecmp_i18n): * text.c (qxetextcasecmp): * text.c (qxetextcasecmp_matching): Create new macro CANONCASE that converts to a canonical mapping and use it to do caseless comparisons instead of DOWNCASE. * alloc.c: * alloc.c (cons_equal): * alloc.c (vector_equal): * alloc.c (string_equal): * bytecode.c (compiled_function_equal): * chartab.c (char_table_entry_equal): * chartab.c (char_table_equal): * data.c (weak_list_equal): * data.c (weak_box_equal): * data.c (ephemeron_equal): * device-msw.c (equal_devmode): * elhash.c (hash_table_equal): * events.c (event_equal): * extents.c (properties_equal): * extents.c (extent_equal): * faces.c: * faces.c (face_equal): * faces.c (face_hash): * floatfns.c (float_equal): * fns.c: * fns.c (bit_vector_equal): * fns.c (plists_differ): * fns.c (Fplists_eq): * fns.c (Fplists_equal): * fns.c (Flax_plists_eq): * fns.c (Flax_plists_equal): * fns.c (internal_equal): * fns.c (internal_equalp): * fns.c (internal_equal_0): * fns.c (syms_of_fns): * glyphs.c (image_instance_equal): * glyphs.c (glyph_equal): * glyphs.c (glyph_hash): * gui.c (gui_item_equal): * lisp.h: * lrecord.h (struct lrecord_implementation): * marker.c (marker_equal): * number.c (bignum_equal): * number.c (ratio_equal): * number.c (bigfloat_equal): * objects.c (color_instance_equal): * objects.c (font_instance_equal): * opaque.c (equal_opaque): * opaque.c (equal_opaque_ptr): * rangetab.c (range_table_equal): * specifier.c (specifier_equal): Add a `foldcase' param to the equal() method and use it to implement `equalp' comparisons. Also add to plists_differ(), although we don't currently use it here. Rewrite internal_equalp(). Implement cross-type vector comparisons. Don't implement our own handling of numeric promotion -- just use the `=' primitive. Add internal_equal_0(), which takes a `foldcase' param and calls either internal_equal() or internal_equalp(). * buffer.h: When given a 0 for buffer (which is the norm when functions don't have a specific buffer available), use the current buffer's table, not `standard-case-table'; otherwise the current settings are ignored. * casetab.c: * casetab.c (set_case_table): When handling old-style vectors of 256 in `set-case-table' don't overwrite the existing table! Instead create a new table and populate. * device-msw.c (sync_printer_with_devmode): * lisp.h: * text.c (lisp_strcasecmp_ascii): Rename lisp_strcasecmp to lisp_strcasecmp_ascii and use lisp_strcasecmp_i18n for caseless comparisons in some places. * elhash.c: Delete unused lisp_string_hash and lisp_string_equal(). * events.h: * keymap-buttons.h: * keymap.h: * keymap.c (keymap_lookup_directly): * keymap.c (keymap_store): * keymap.c (FROB): * keymap.c (key_desc_list_to_event): * keymap.c (describe_map_mapper): * keymap.c (INCLUDE_BUTTON_ZERO): New file keymap-buttons.h; use to handle buttons 1-26 in place of duplicating code 26 times. * frame-gtk.c (allocate_gtk_frame_struct): * frame-msw.c (mswindows_init_frame_1): Fix some comments about internal_equal() in redisplay that don't apply any more. * keymap-slots.h: * keymap.c: New file keymap-slots.h. Use it to notate the slots in a keymap structure, similar to frameslots.h or coding-system-slots.h. * keymap.c (MARKED_SLOT): * keymap.c (keymap_equal): * keymap.c (keymap_hash): Implement. tests/ChangeLog addition: 2010-02-01 Ben Wing <ben@xemacs.org> * automated/case-tests.el: * automated/case-tests.el (uni-mappings): * automated/search-tests.el: Delete old pristine-case-table code. Rewrite the Unicode torture test to take into account whether overlapping mappings exist for more than one character, and not doing the upcase/downcase comparisons in such cases. * automated/lisp-tests.el (foo): * automated/lisp-tests.el (string-variable): * automated/lisp-tests.el (featurep): Replace Assert (equal ... with Assert-equal; same for other types of equality. Replace some awkward equivalents of Assert-equalp with Assert-equalp. Add lots of equalp tests. * automated/case-tests.el: * automated/regexp-tests.el: * automated/search-tests.el: Fix up the comments at the top of the files. Move rules about where to put tests into case-tests.el. * automated/test-harness.el: * automated/test-harness.el (test-harness-aborted-summary-template): New. * automated/test-harness.el (test-harness-from-buffer): * automated/test-harness.el (batch-test-emacs): Fix Assert-test-not. Create Assert-not-equal and variants. Delete the doc strings from all these convenience functions to avoid excessive repetition; instead use one copy in a comment.

   This is used for communication to and from the caller

   When `getopt' returns -1, this is the index of the first of the
   non-option elements that the caller should itself scan.

   Otherwise, `optind' communicates from one call to the next

/* Describe the long-named options requested by the application.
   The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
   of `struct option' terminated by an element containing a name which is
   zero.

   The field `has_arg' is:
   no_argument		(or 0) if the option does not take an argument,
   required_argument	(or 1) if the option requires an argument,
   optional_argument 	(or 2) if the option takes an optional argument.

   If the field `flag' is not NULL, it points to a variable that is set
   to the value given in the field `val' when the option is found, but
   left unchanged if the option is not found.

   To have a long-named option do something other than set an `int' to
   a compiled-in constant, such as set a value from `optarg', set the
   option's `flag' field to zero and its `val' field to a nonzero
   value (the equivalent single-letter option character, if there is
   one).  For long options that have a zero `flag' field, `getopt'
   returns the contents of the `val' field.  */
