* vi: fix backward search with GNU regexRon Yorston2021-06-211-20/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | With FEATURE_VI_REGEX_SEARCH enabled backward searches don't work. This is problematic on distros that enable regexes, such as Tiny Core Linux and Fedora. When calling GNU re_search() with a negative range parameter (indicating a backward search) the start offset must be set to the end of the area being searched. The return value of re_search() is the offset of the matched pattern from the start of the area being searched. For a successful search (positive return value) char_search() can return the pointer to the start of the area plus the offset. FEATURE_VI_REGEX_SEARCH isn't enabled by default but when it is: function old new delta char_search 256 247 -9 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-9) Total: -9 bytes Signed-off-by: Andrey Dobrovolsky <andrey.dobrovolsky.odessa@gmail.com> Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* vi: reject change command when motion failsRon Yorston2021-06-161-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | If the motion command used to define the range of a change, yank or delete fails the whole command should be rejected. BusyBox vi already handled failed searches in these circumstances. Add some more cases: - non-existent mark: d'x - movement beyond end of file: c99999+ or 99999<< This is implemented using a global variable which is set when a command error is detected. Unlike the case of motion within a line it's insufficient to check that the motion command doesn't move the cursor: this fails to process 'LyL' correctly, for example, as the second 'L' doesn't move the cursor. function old new delta indicate_error 75 82 +7 find_range 686 692 +6 do_cmd 4851 4852 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 14/0) Total: 14 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* vi: up/down motion beyond end of file should failRon Yorston2021-06-161-25/+38
| | | | | | | | | | | | | | | | | | | | | In traditional vi and vim line motion commands ('+'/'-'/'j'/'k') fail if the movement would exceed the bounds of the file. BusyBox vi allowed such commands to succeed, leaving the cursor on the first or last character of the file. Make BusyBox vi work like vi/vim. For the 'G'/'H'/'L' commands traditional vi treats an out of bounds result as an error, vim doesn't. BusyBox vi behaves like vim, both before and after this patch. function old new delta do_cmd 4785 4851 +66 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 66/0) Total: 66 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
