Usually people send the patches to themself to tune their delivery scripts, not to the list.
Both traditional vi and vim use basic regular expressions for search. Also, they don't allow matches to extend across line endings. Thus with the file: 123 234 the search '/2.*4$' should find the second '2', not the first. Make BusyBox vi do the same. Whether or not VI_REGEX_SEARCH is enabled: function old new delta ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/0 up/down: 0/0) Total: 0 bytes Signed-off-by: Andrey Dobrovolsky <[email protected]> Signed-off-by: Ron Yorston <[email protected]> --- editors/vi.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/editors/vi.c b/editors/vi.c index f0bbc9518..959362b25 100644 --- a/editors/vi.c +++ b/editors/vi.c @@ -2378,9 +2378,9 @@ static char *char_search(char *p, const char *pat, int dir_and_range) char *q; int i, size, range, start;- re_syntax_options = RE_SYNTAX_POSIX_EXTENDED;+ re_syntax_options = RE_SYNTAX_POSIX_BASIC & (~RE_DOT_NEWLINE); if (ignorecase) - re_syntax_options = RE_SYNTAX_POSIX_EXTENDED | RE_ICASE; + re_syntax_options |= RE_ICASE;memset(&preg, 0, sizeof(preg));err = re_compile_pattern(pat, strlen(pat), &preg); _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
