Unicode-capable srfi-14 charsets
* libguile/Makefile.am: distribute new files srfi-14.i.c and unidata_to_charset.pl * chars.c (scm_c_upcase, scm_c_downcase): use unicode-enable toupper and tolower * libguile/srfi-14.h (scm_t_char_range, scm_t_char_set): new structures to describe char-sets (scm_t_char_set_cursor): new structure to describe char-set-cursors (SCM_BITS_PER_LONG): removed (SCM_CHARSET_GET): calls function New declarations for scm_i_charset_get, scm_i_charset_set, scm_i_charset_unset, and scm_debug_char_set. * test-suite/tests/srfi-14.test: new tests * libguile/srfi-14.c (SCM_CHARSET_DATA): new macro (SCM_CHARSET_SET, SCM_CHARSET_UNSET): call function (BYTES_PER_CHARSET, LONGS_PER_CHARSET): removed (scm_i_charset_get, scm_i_charset_set, scm_i_charset_unset) (charsets_equal, charsets_leq, charsets_union) (charsets_intersection, charsets_complement, charsets_xor): new functions that are low-level charset operators (charset_print, charset_free): modified for new charset struct (charset_cursor_print, charset_cursor_free): new function (make_char_set, scm_char_set_p, scm_char_set_eq, scm_car_set_leq) (scm_char_set_hash, scm_char_set_cursor, scm_char_set_ref) (scm_char_set_cursor_next, scm_end_of_char_set_p, scm_char_set_fold) (scm_char_set_unfold, scm_char_set_unfold_x, scm_char_set_for_each) (scm_char_set_map, scm_char_set_copy, scm_char_set, scm_list_to_char_set) (scm_list_to_char_set_x, scm_string_to_char_set, scm_string_to_char_set_x) (scm_char_set_filter, scm_char_set_filter_x, scm_ucs_range_to_char_set) (scm_ucs_range_to_char_set_x, scm_to_char_set, scm_char_set_size) (scm_char_set_count, scm_char_set_to_list, scm_char_set_to_string) (scm_char_set_contains_p, scm_char_set_every, scm_char_set_any) (scm_char_set_adjoin, scm_char_set_delete, scm_char_set_adjoin_x) (scm_char_set_delete_x, scm_char_set_complement, scm_char_set_union) (scm_char_set_intersection, scm_char_set_difference, scm_char_set_xor) (scm_char_set_diff_plus_intersection, scm_char_set_complement_x) (scm_char_set_union_x, scm_char_set_intersection_x, scm_char_set_difference_x) (scm_char_set_xor_x, scm_char_set_diff_plus_intersection_x): modified to use new charset and charset-cursor data structures (CSET_BLANK_PRED, CSET_SYMBOL_PRED, CSET_PUNCT_PRED, CSET_LOWER_PRED) (CSET_UPPER_PRED, CSET_LETTER_PRED, CSET_DIGIT_PRED, CSET_WHITESPACE_PRED) (CSET_CONTROL_PRED, CSET_HEX_DIGIT_PRED, CSET_ASCII_PRED, CSET_LETTER_PRED) (CSET_LETTER_AND_DIGIT_PRED, CSET_PRINTING_PRED, CSET_TRUE_PRED) (CSET_FALSE_PRED): removed (scm_srfi_14_compute_char_sets): removed - too slow to iterate over all of unicode at startup (scm_debug_char_set) [SCM_CHARSET_DEBUG]: new function
