2021-06-02vi: make cursor positioning more vi compatibleRon Yorston
Commit 24effc7a3 (vi: cursor positioning after whole-line 'y') tried to save a few bytes by treating whole-line deletion the same as whole-line yank. If the deletion removed the last lines of the file the cursor was left beyond the end of the file. Revert the part of the commit related to whole-line deletion. Position the cursor on the first non-whitespace character of the line when whole lines are 'put'. function old new delta do_cmd 4759 4781 +22 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 22/0) Total: 22 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-05-04vi: cursor positioning after whole-line 'y'Ron Yorston
The 'y' command to yank text should leave the cursor at the start of the range. This mostly works correctly in BusyBox vi but not for whole-line yanks with backward motion, e.g. '2yk' to yank two lines backwards. In this case the cursor is left at the end of the range. Fix this by returning the actual range from find_range(). Cursor positioning following whole-line deletion is inconsistent between vim and traditional vi. For BusyBox vi chose the option that uses least code without being exactly compatible with either. Also, find_range() preserved the value of 'dot', the current cursor position. Since this isn't used by either caller of find_range() we can save a few bytes by not bothering. function old new delta do_cmd 4730 4759 +29 find_range 749 686 -63 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 29/-63) Total: -34 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

seconds This allows to fix a problem that we wait for renew replies for up to half the lease (!!!) if they never come. Make it so that lease of 60 seconds is not "rounded up" to 120 seconds - set lower "sanity limit" to 30 seconds. After 3 failed renew attempts, switch to rebind. After this change, we can have more flexible choice of when to do the first renew - does not need to be equal to lease / 2. function old new delta udhcpc6_main 2568 2576 +8 .rodata 103339 103294 -45 udhcpc_main 2609 2550 -59 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/2 up/down: 8/-104) Total: -96 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-30vi: fix empty line range regressionRon Yorston
Commit 7a8ceb4eb (vi: changes to line addresses for colon commands) was supposed to address the issue: When the last address is empty it should refer to the current line. This was intended to allow ranges of the form '1,' with an empty last address. It should have been expressed as: When the last address is empty *and the second last isn't* it should refer to the current line. Otherwise a command like ':w' only writes the current line resulting in serious loss of data. function old new delta colon 3906 3911 +5 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 5/0) Total: 5 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Track the current and alternate filenames. The placeholders '%' and '#' can be used in arguments to colon commands to represent the current and alternate filenames respectively.

2021-04-28vi: fix buffer overrun; code shrinkRon Yorston
It was possible for get_input_line() to store its NUL terminator one character beyond the end of its buffer. Code shrink in colon(): - Certain colon commands can be matched exactly, as any shorter string would be matched earlier, e.g. ':wq' versus ':write'. - Command matching is now case sensitive so there's no need to check for 'N' or 'Q' suffixes. - Rewrite how commands and arguments are split. function old new delta colon 3848 3751 -97 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-97) Total: -97 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-04-28vi: improvements to ':read' commandRon Yorston
Improvements to ':read': - When a file is read into the current buffer the cursor should be placed on the first line read. - If invoked without supplying a filename the current filename should be used. This is similar to how ':edit' works. - The code for ':edit' included an explicit check that the current filename was non-empty. Both vim and traditional vi accept non-empty filenames, only issuing an error message when an attempt to use such a name fails. - Allow undo of a file read. function old new delta file_insert 367 382 +15 colon 3841 3848 +7 .rodata 105236 105218 -18 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 22/-18) Total: 4 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-28vi: 'ZZ' should warn if there are more files to editRon Yorston
When 'ZZ' was used to save the current file and more files were available to edit BusyBox vi immediately moved on to the next file.

2021-04-28vi: saving unnamed file in readonly modeRon Yorston
Suppose vi is started with the command 'vi -R', that is, in readonly mode with no filename. Attempting to save the file with 'ZZ' or ':w' results in the message: '(null)' is read only Skip the code which prints this if no filename was provided, thus falling through to file_write() which gives the more helpful message 'No current filename'. function old new delta colon 3867 3874 +7 do_cmd 4668 4673 +5 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 12/0) Total: 12 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-28vi: changes to line addresses for colon commandsRon Yorston
Make line addresses behave more like vi: - Vi allows the user to enter an arbitrary number of addresses, though only the last two are used. This simplifies get_address() by reducing the amount of state that needs to be carried. - When a command requires a single address the last one entered is used. - If addresses are separated by a ';' instead of a ',' the current line is updated to the left address. This may be useful when a search is used to specify a range, e.g. ':/first/;/last/d'. - When the last address is empty it should refer to the current line. function old new delta colon 3855 3834 -21 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-21) Total: -21 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
