From 836d0a7ee450893e7479b5f93a501454582955a2 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Thu, 29 Nov 2018 14:19:57 +0100 Subject: vi: fix FEATURE_VI_REGEX_SEARCH to respect LIMITED (one-line) search If busybox is compiled with FEATURE_VI_REGEX_SEARCH enabled, command ":s/x/y/" searches not only in the current line, but continues search after it. This makes range searches (":1,3s/x/y/") work incorrect. For example file "./test": 1 2 3 $ vi ./test :1,2s/3/e/ gives us: 1 2 e function old new delta char_search 213 241 +28 Signed-off-by: Denys Vlasenko --- editors/vi.c | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) (limited to 'editors/vi.c') diff --git a/editors/vi.c b/editors/vi.c index 2aa0ad9dd..bff47250d 100644 --- a/editors/vi.c +++ b/editors/vi.c @@ -255,8 +255,8 @@ enum { YANKDEL = TRUE, FORWARD = 1, // code depends on "1" for array index BACK = -1, // code depends on "-1" for array index - LIMITED = 0, // how much of text[] in char_search - FULL = 1, // how much of text[] in char_search + LIMITED = 0, // char_search() only current line + FULL = 1, // char_search() to the end/beginning of entire text S_BEFORE_WS = 1, // used in skip_thing() for moving "dot" S_TO_WS = 2, // used in skip_thing() for moving "dot" @@ -1914,10 +1914,15 @@ static char *char_search(char *p, const char *pat, int dir, int range) return p; } - // assume a LIMITED forward search - q = end - 1; - if (dir == BACK) + q = end - 1; // if FULL + if (range == LIMITED) + q = next_line(p); + if (dir == BACK) { q = text; + if (range == LIMITED) + q = prev_line(p); + } + // RANGE could be negative if we are searching backwards range = q - p; q = p; -- cgit v1.2.3
