2019-02-11vi: further fixes to undo after autoindentRon Yorston
Commit bb983f30e (vi: fix faulty undo after autoinsert) has a number of problems: - The commit message refers to 'autoinsert' when it really means 'autoindent'. - The indentation of undo_push_insert() was incorrect. - Most seriously the commit only fixed the problem for cases where the indentation was exactly one character. This is because undo_push() only allows single characters to be queued for UNDO_INS_QUEUED. Lifting this restriction allows the example given in the previous commit message (with a three character indent) to work. function old new delta undo_push 406 435 +29 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 29/0) Total: 29 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-02-08vi: fix faulty undo after autoinsertRon Yorston
Enable autoinsert and enter the following with an indent of three spaces: line 1 line 2 Using 'u' to undo the last insert results in: line1e 2 The insertion of the indent hasn't been properly recorded. Since recording insertions is a common operation add a convenience function, undo_push_insert(), to handle this and use it to record the autoindent correctly. function old new delta undo_push_insert - 36 +36 string_insert 133 129 -4 char_insert 518 473 -45 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 0/2 up/down: 36/-49) Total: -13 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-12-03vi: correctly detect when a deletion empties the bufferRon Yorston
Michał Berger has reported two issues: - Repeatedly deleting and undoing the deletion of the last line results in characters being lost from the end of the line. - Deleting the bottom line twice then attempting to undo each of these deletions results in a segfault. The problem seems to be an incorrect test for whether the text buffer is empty.

2018-11-29vi: fix FEATURE_VI_REGEX_SEARCH to respect LIMITED (one-line) searchDenys Vlasenko
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 <vda.linux@googlemail.com>

2017-03-24vi: avoid touching a new file with ZZ when no editing has been doneYousong Zhou
This is the behaviour observed with standard vim and busybox vi of at least 1.22.1. It was changed with commit "32afd3a vi: some simplifications" which happened before 1.23.0. Mistyping filename on command line happens fairly often and it's better we restore the old behaviour to avoid a few unnecessary flash writes and sometimes efforts of debugging bugs caused by those unneeded stray files.

2017-03-13vi: don't touch file with :x when modified_count == 0Denys Vlasenko
Along with it, there are other changes - Check for uppercase X is removed as the expression will be always false and :X itself is another totally different command in standard vim - The status line will show number of written lines instead of lines requested by the colon command. This is also how the standard vim is doing, though the difference is that '!' has to be explicitly specified in vim to allow partial writes Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-09-28vi: fix '' command (goto to prev context)Denys Vlasenko
The '' command in vi doesn't currently work because after the first apostrophe is read, the next character is converted to an integer between 0 and 25 inclusive (for indexing the array of marks). The comparison of the converted character with an apostrophe therefore never succeeds, meaning that '' doesn't do anything.
