2021-04-20vi: make de-indentation with ctrl-D more like vimRon Yorston
Commit ac6495f6f (vi: allow ctrl-D to reduce indentation) treated ctrl-D during autoindent as a backspace. This was adequate for indentation using tabs but doesn't work well with the expandtab option. In the latter case it's necessary to backspace over all the spaces. Make ctrl-D work correctly when spaces are present in the indent. Also, make it behave more like vim: - ctrl-D is independent of autoindent; - indentation is reduced even when the cursor isn't positioned at the end of the indent. function old new delta char_insert 679 717 +38 get_column - 37 +37 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 1/0 up/down: 75/0) Total: 75 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-04-20vi: add expandtab optionRon Yorston
This implements the vim option expandtab in BusyBox vi. From vim help: In Insert mode: Use the appropriate number of spaces to insert a <Tab>. Spaces are used in indents with the '>' and '<' commands and when 'autoindent' is on. To insert a real tab when 'expandtab' is on, use CTRL-V<Tab>. This implementation doesn't change how BusyBox vi handles autoindent: it continues to copy the indentation from a neighbouring line. If that line has tabs in its indentation so too will the new line. function old new delta char_insert 563 679 +116 next_column - 48 +48 .rodata 105211 105236 +25 colon 3844 3855 +11 refresh 1000 982 -18 move_to_col 83 59 -24 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 3/2 up/down: 200/-42) Total: 158 bytes Signed-off-by: Peter D <urmum69@snopyta.org> Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-15vi: allow line addresses to have an offsetRon Yorston
Line addresses in colon commands can be defined using an expression that includes '+' or '-' operators. The implementation follows traditional vi: - The first term in the expression defines an address. It can be an absolute line number, '.', '$', a search or a marker. - The second and subsequent terms must be non-negative integers. - If the first term is missing '.' is assumed. If the operator is missing addition is assumed. If the final term in missing an offset of 1 is assumed. Thus the following are valid addresses: .+1 .+ + .1 .-1 .- - The following are not valid (though they are in vim): .+$ .$ 2+. function old new delta colon 3701 3844 +143 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 143/0) Total: 143 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-04-15vi: position cursor on last column of tabRon Yorston
Vi places the cursor on the last column of a tab character whereas BusyBox vi puts it on the first. This is disconcerting for experienced vi users and makes it impossible to distinguish visually between an empty line and one containing just a tab. It wasn't always this way. Prior to commit e3cbfb91d (vi: introduce FEATURE_VI_8BIT) BusyBox vi also put the cursor on the last column. However there were problems with cursor positioning when text was inserted before a tab. Commit eaabf0675 (vi: multiple fixes by Natanael Copa) includes a partial attempt to fix this. (The code is still present but it's never executed. Clever compilers optimise it away.) Revert the changes of commit e3cbfb91d and fix the insert problem for all tabs, not just the first. To quote Natanael: "Costs a few bytes but its worth it imho". function old new delta refresh 974 1000 +26 move_to_col 81 83 +2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 28/0) Total: 28 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-04-15vi: correctly record deleted charactersRon Yorston
The undo queue didn't record deleted characters properly. For example, insert some text, backspace over a couple of characters then exit insert mode.

2021-04-13build system: avoid build failure during bisectionRon Yorston
Commit 4bdc914ff (build system: fix compiler warnings) added a test on the return value of fgets() in split-include.c. During bisection it's possible to go back to a state where a configuration value didn't exist. This results in an empty include file corresponding to the missing feature. If a subsequent bisection returns to a state where the feature exists split-include treats the empty file as an error and the build fails. Add a call to ferror() to distinguish between fgets() failing due to an error and due to there being no data to read.

2021-04-13watchdog: make open-write-close-open functionality a config knobRasmus Villemoes
The behaviour introduced by commit 31c765081dc4 ("watchdog: stop watchdog first on startup") causes warnings in the kernel log when the nowayout feature is enabled: [ 16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped! [ 16.212196] watchdog: watchdog0: watchdog did not stop! The latter may also appear by itself in case the watchdog is of the type that cannot be stopped once started (e.g. the common always-running gpio_wdt kind). These warnings can be somewhat ominous and distracting, so allow configuring whether to use this open-write-close-open sequence rather than just open.
