2021-04-08vi: changes to option handlingRon Yorston
Since commit 70ee23399 (vi: code shrink) the ':set' command is unable to process multiple options on a line. Fix this by temporarily null-terminating each option. Change the default setting for all options to off to match vim. Actually, 'flash' isn't an option in vim, only traditional vi, where it's on by default. In vim the corresponding option is 'visualbell' which defaults to off. POSIX doesn't have either of these. Allow the abbreviation 'ts' for the 'tabstop' option. Issue an error message if: - an option is not implemented - an option that takes a value has no '=' or has a 'no' prefix - a boolean option has a '=' function old new delta colon 2944 3003 +59 .rodata 103171 103189 +18 vi_main 274 270 -4 setops 73 - -73 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 2/1 up/down: 77/-77) Total: 0 bytes v2: Try harder to detect invalid options.

2021-03-30vi: deal with invalid movements in shift commandsRon Yorston
Since commit 25d259264 (vi: make buffer handling more vi-like) find_range() can return early when an invalid movement is specified. The call to find_range() in the code that handles shift commands ('<' and '>') doesn't check for this condition. Previously this only resulted in the current line being shifted but it can now result in a segfault. Check for an invalid movement and notify the user without taking any further action. function old new delta do_cmd 4890 4898 +8 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 8/0) Total: 8 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-03-29vi: allow motion count for change/delete/yank/shiftRon Yorston
The motion that determines the range of a change, delete, yank or shift operation can have its own count. Thus the commands '5dd' and 'd5d' are equivalent: both delete 5 lines. When the command itself also has a count the two values are multiplied. Thus the command '2d3w' deletes 6 words and '2D3G' deletes from the current line to line 6. (When dealing with structured data it might make sense to think in units of 3 words so '2d3w' is deleting 2 such units. It doesn't seem quite as sensible to express 'delete from current line to line 6' as '2D3G' but vi permits it.) function old new delta get_motion_char - 68 +68 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 0/0 up/down: 68/0) Total: 68 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

If the name of the file being written doesn't match the current filename and the output file already exists vi should issue a warning and not overwrite the file. Because the test only compares the file names it's somewhat over- protective. If the current file name is 'my_text' and the user tries to save to './my_text' they'll be prevented from doing so. function old new delta colon 3092 3151 +59 .rodata 105118 105146 +28 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 87/0) Total: 87 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: make buffer handling more vi-likeRon Yorston
Vi places text affected by change/delete/yank operations into a buffer. The contents of such buffers can be restored with the put commands, 'p' or 'P'. These behave differently depending on whether the buffer contains whole lines or partial lines. For whole lines the text is copied into the file on the line before (P) or after (p) the current line. For partial lines the text is copied before or after the current cursor position. Whether an operation results in whole or partial lines depends on the command used. BusyBox vi treats any buffer with a newline as though it contained whole lines. This is incorrect. Deleting multiple words across a line boundary results in a buffer with a newline but not having whole lines. Rework how buffers are handled to behave more like vi. function old new delta static.text_yank 79 99 +20 colon 3092 3097 +5 edit_file 885 887 +2 yank_delete 127 112 -15 .rodata 105139 105101 -38 find_range 514 467 -47 do_cmd 5088 4842 -246 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/4 up/down: 27/-346) Total: -319 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: code shrinkRon Yorston
I was puzzled by code in find_range() which handles forward word movement. It included a test to see if we're at the start of a word. Since these are forward word movements surely we'd expect to be at the start of a word? In fact, the test was intended to fix a problem with changes to the last word in a file, as discussed in the thread starting here: http://lists.busybox.net/pipermail/busybox/2004-January/044552.html The code can be simplified by testing directly for end of file instead of indirectly for not being at the start of a word. Since trailing whitespace is now handled in do_cmd() the code to back up off a newline is no longer required. function old new delta find_range 619 514 -105 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-105) Total: -105 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-03-29vi: fix word operations across line boundariesRon Yorston
Commit 4b49422a0 (vi: fix changes to word at end of line. Closes 11796) fixed a problem where an operation on a word at the end of a line followed by a line starting with whitespace incorrectly joined the lines. However it also broke the case where operating on multiple words across a line boundary *should* join the lines. Fix this by detecting when trailing whitepace in a word operation includes a newline. Whitespace beyond the newline is excluded from consideration. function old new delta do_cmd 5083 5088 +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>

2021-02-02vi: fix range selection by forward character motionRon Yorston
Selection of ranges for change/delete/yank by forward character motion commands (SPACE or 'l') was incorrect. The range was always one character whereas vi allows the size of the range to be specified. Fix this by executing the motion command the required number of times. There is a complication when the range is at the end of a line. We need to distinguish between a range which excludes the last character and one which includes it. This requires comparing the actual range with that expected from the command count. (With the additional quirk that a command count of zero is equivalent to a command count of one.) function old new delta find_range 587 619 +32 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 32/0) Total: 32 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Handling of string searches in colon commands (e.g ':/pat1/,/pat2/cmd') differ from standard vi: - As reported in bug 10321 such searches can't be repeated using the 'n' command. This is because the last search pattern isn't updated. - The search also can't be repeated using the command '://' because an empty search pattern doesn't imply the use of the last search pattern. - Such searches should start on the line after the current line, otherwise '://' never moves to the next occurrence of the pattern. This can also affect other cases where line ranges are specified using search patterns.

2019-07-02libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne
Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.

2019-04-28vi: fix changes to word at end of line. Closes 11796Ron Yorston
As reported in bug 11796 BusyBox vi incorrectly handles changes to a word at the end of a line. If the following line starts with whitespace changing or deleting the last word of a line with the 'cw' or 'dw' commands causes the lines to be joined. This happens because the range for the change returned by find_range() covers all whitespace after the word, including newlines. The problem can be fixed by setting 'ml' to zero to indicate to yank_delete() that processing should stop at the end of the current line. However, this results in a new problem. 'dw' correctly deletes all whitespace following the word but so does 'cw', which should preserve the trailing whitespace. To fix this the code to omit whitespace from the change is modified to include all whitespace not just blanks. function old new delta do_cmd 5034 5069 +35 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 35/0) Total: 35 bytes Reported-by: David Kelly <david.kelly@liberica.ch> Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
