Refactor out sequence-oriented builtins from fns.c to the new sequence.c. src/ChangeLog addition: 2011-12-04 Aidan Kehoe <kehoea@parhasard.net> * Makefile.in.in (objs): * depend: Add sequence.o to the list of objects and dependencies. * alloc.c: * alloc.c (mark_bit_vector): * alloc.c (print_bit_vector): * alloc.c (bit_vector_equal): * alloc.c (internal_bit_vector_equalp_hash): * alloc.c (bit_vector_hash): * alloc.c (init_alloc_once_early): Move the implementation of the bit vector type here from fns.c. * emacs.c (main_1): Call syms_of_sequence() here, now sequence.c is included. * fns.c (Fold_rassq): Move this together with the rest of the Fold_* functions. * fns.c: * fns.c (syms_of_fns): Move most functions dealing with sequences generally, and especially those taking key arguments, to a separate file, sequence.c. * general-slots.h: Qyes_or_no_p belong here, not fns.c. * lisp.h: Make Flist_length available here, it's used by sequence.c * sequence.c: * sequence.c (check_sequence_range): * sequence.c (Flength): * sequence.c (check_other_nokey): * sequence.c (check_other_key): * sequence.c (check_if_key): * sequence.c (check_match_eq_key): * sequence.c (check_match_eql_key): * sequence.c (check_match_equal_key): * sequence.c (check_match_equalp_key): * sequence.c (check_match_other_key): * sequence.c (check_lss_key): * sequence.c (check_lss_key_car): * sequence.c (check_string_lessp_key): * sequence.c (check_string_lessp_key_car): * sequence.c (get_check_match_function_1): * sequence.c (get_merge_predicate): * sequence.c (count_with_tail): * sequence.c (list_count_from_end): * sequence.c (string_count_from_end): * sequence.c (Fcount): * sequence.c (Fsubseq): * sequence.c (list_position_cons_before): * sequence.c (FmemberX): * sequence.c (Fadjoin): * sequence.c (FassocX): * sequence.c (FrassocX): * sequence.c (position): * sequence.c (Fposition): * sequence.c (Ffind): * sequence.c (delq_no_quit_and_free_cons): * sequence.c (FdeleteX): * sequence.c (FremoveX): * sequence.c (list_delete_duplicates_from_end): * sequence.c (Fdelete_duplicates): * sequence.c (Fremove_duplicates): * sequence.c (Fnreverse): * sequence.c (Freverse): * sequence.c (list_merge): * sequence.c (array_merge): * sequence.c (list_array_merge_into_list): * sequence.c (list_list_merge_into_array): * sequence.c (list_array_merge_into_array): * sequence.c (Fmerge): * sequence.c (list_sort): * sequence.c (array_sort): * sequence.c (FsortX): * sequence.c (Ffill): * sequence.c (mapcarX): * sequence.c (shortest_length_among_sequences): * sequence.c (Fmapconcat): * sequence.c (FmapcarX): * sequence.c (Fmapvector): * sequence.c (Fmapcan): * sequence.c (Fmap): * sequence.c (Fmap_into): * sequence.c (Fsome): * sequence.c (Fevery): * sequence.c (Freduce): * sequence.c (replace_string_range_1): * sequence.c (Freplace): * sequence.c (Fnsubstitute): * sequence.c (Fsubstitute): * sequence.c (subst): * sequence.c (sublis): * sequence.c (Fsublis): * sequence.c (nsublis): * sequence.c (Fnsublis): * sequence.c (Fsubst): * sequence.c (Fnsubst): * sequence.c (tree_equal): * sequence.c (Ftree_equal): * sequence.c (mismatch_from_end): * sequence.c (mismatch_list_list): * sequence.c (mismatch_list_string): * sequence.c (mismatch_list_array): * sequence.c (mismatch_string_array): * sequence.c (mismatch_string_string): * sequence.c (mismatch_array_array): * sequence.c (get_mismatch_func): * sequence.c (Fmismatch): * sequence.c (Fsearch): * sequence.c (venn): * sequence.c (nvenn): * sequence.c (Funion): * sequence.c (Fset_exclusive_or): * sequence.c (Fnset_exclusive_or): * sequence.c (syms_of_sequence): Add this file, containing those general functions that dealt with sequences that were in fns.c. * symsinit.h: Make syms_of_sequence() available here. man/ChangeLog addition: 2011-12-04 Aidan Kehoe <kehoea@parhasard.net> * internals/internals.texi (Basic Lisp Modules): Document sequence.c here too.

(defun x-use-halfwidth-roman-font (fullwidth-charset roman-registry)
  "Maybe set charset registry of the 'ascii charset to ROMAN-REGISTRY.

Do this only if:
 - the current display is an X device
 - the displayed width of FULLWIDTH-CHARSET is twice the displayed
   width of the 'ascii charset, but only when using ROMAN-REGISTRY.

Traditionally, Asian characters have been displayed so that they
occupy exactly twice the screen space of ASCII (`halfwidth')
characters.  On many systems, e.g. Sun CDE systems, this can only be
achieved by using a national variant roman font to display ASCII."
