From 27d101832ada36e431ae6cdecb5c82a180566377 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Fri, 17 Apr 2020 07:57:25 -0700 Subject: Prefer more inline functions in character.h * src/buffer.h (fetch_char_advance, fetch_char_advance_no_check) (buf_next_char_len, next_char_len, buf_prev_char_len) (prev_char_len, inc_both, dec_both): New inline functions, replacing the old character.h macros FETCH_CHAR_ADVANCE, FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS, DEC_POS, INC_BOTH, DEC_BOTH respectively. All callers changed. These new functions all assume buffer primitives and so need to be here rather than in character.h. * src/casefiddle.c (make_char_unibyte): New static function, replacing the old MAKE_CHAR_UNIBYTE macro. All callers changed. (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead of open-coding it. * src/ccl.c (GET_TRANSLATION_TABLE): New static function, replacing the old macro of the same name. * src/character.c (string_char): Omit 2nd arg. 3rd arg can no longer be NULL. All callers changed. * src/character.h (SINGLE_BYTE_CHAR_P): Move up. (MAKE_CHAR_UNIBYTE, MAKE_CHAR_MULTIBYTE, PREV_CHAR_BOUNDARY) (STRING_CHAR_AND_LENGTH, STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_ADVANCE) (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE) (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, FETCH_CHAR_ADVANCE) (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, INC_BOTH) (DEC_BOTH, BUF_INC_POS, BUF_DEC_POS): Remove. (make_char_multibyte): New static function, replacing the old macro MAKE_CHAR_MULTIBYTE. All callers changed. (CHAR_STRING_ADVANCE): Remove; all callers changed to use CHAR_STRING. (NEXT_CHAR_BOUNDARY): Remove; it was unused. (raw_prev_char_len): New inline function, replacing the old PREV_CHAR_BOUNDARY macro. All callers changed. (string_char_and_length): New inline function, replacing the old STRING_CHAR_AND_LENGTH macro. All callers changed. (STRING_CHAR): Rewrite in terms of string_char_and_length. (string_char_advance): New inline function, replacing the old STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_advance): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_as_multibyte_advance): New inline function, replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro. All callers changed. (fetch_string_char_advance_no_check): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro. All callers changed. * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used. * src/syntax.c (scan_lists): Use dec_bytepos instead of open-coding it. * src/xdisp.c (string_char_and_length): Rename from string_char_and_length to avoid name conflict with new function in character.h. All callers changed. --- src/regex-emacs.c | 28 ++++++++++------------------ 1 file changed, 10 insertions(+), 18 deletions(-) (limited to 'src/regex-emacs.c') diff --git a/src/regex-emacs.c b/src/regex-emacs.c index 0ae004e4636..9fd23943402 100644 --- a/src/regex-emacs.c +++ b/src/regex-emacs.c @@ -58,7 +58,7 @@ #define RE_STRING_CHAR(p, multibyte) \ (multibyte ?
