From: tomo Date: Mon, 12 Jun 2000 09:03:24 +0000 (+0000) Subject: (Vchar_attribute_hash_table): New variable. X-Git-Tag: r21-2-34-utf-2000-0_16-1~36 X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=13aacc9bac827f73300c925094de2322d9214bb2;p=chise%2Fxemacs-chise.git- (Vchar_attribute_hash_table): New variable. (Vcharacter_attribute_table): Deleted. (Vcharacter_name_table): Deleted. (put_char_attribute): Deleted. (remove_char_attribute): Deleted. (struct char_attribute_alist_closure): New structure. (add_char_attribute_alist_mapper): New function. (Fchar_attribute_alist): Use `Vchar_attribute_hash_table' instead of `Vcharacter_attribute_table' and `Vcharacter_name_table'. (Fget_char_attribute): Likewise. (Fput_char_attribute): Likewise. (Fremove_char_attribute): Use `Vchar_attribute_hash_table' instead of `remove_char_attribute'. (Fdefine_char): Return character. (vars_of_mule_charset): Don't setup `Vcharacter_attribute_table' and `Vcharacter_name_table'. (complex_vars_of_mule_charset): Likewise `Vchar_attribute_hash_table'. --- diff --git a/src/mule-charset.c b/src/mule-charset.c index 91376d7..5c9d019 100644 --- a/src/mule-charset.c +++ b/src/mule-charset.c @@ -421,8 +421,7 @@ put_char_id_table (Emchar ch, Lisp_Object value, Lisp_Object table) } -Lisp_Object Vcharacter_attribute_table; -Lisp_Object Vcharacter_name_table; +Lisp_Object Vchar_attribute_hash_table; Lisp_Object Vcharacter_ideographic_radical_table; Lisp_Object Vcharacter_ideographic_strokes_table; Lisp_Object Vcharacter_total_strokes_table; @@ -462,12 +461,6 @@ Lisp_Object put_char_ccs_code_point (Lisp_Object character, Lisp_Object ccs, Lisp_Object value); Lisp_Object remove_char_ccs (Lisp_Object character, Lisp_Object ccs); -Lisp_Object put_char_attribute (Lisp_Object character, - Lisp_Object attribute, Lisp_Object value); -Lisp_Object remove_char_attribute (Lisp_Object character, - Lisp_Object attribute); - - Emchar to_char_id (Lisp_Object v, char* err_msg, Lisp_Object err_arg) { @@ -555,22 +548,58 @@ Return variants of CHARACTER.
