@ -67,123 +67,6 @@ config SED
sed is used to perform text transformations on a file
or input from a pipeline.
config VI
bool "vi"
default y
help
'vi' is a text editor. More specifically, it is the One True
text editor <grin>. It does, however, have a rather steep
learning curve. If you are not already comfortable with 'vi'
you may wish to use something else.
config FEATURE_VI_MAX_LEN
int "Maximum screen width in vi"
range 256 16384
default 4096
depends on VI
help
Contrary to what you may think, this is not eating much.
Make it smaller than 4k only if you are very limited on memory.
config FEATURE_VI_8BIT
bool "Allow vi to display 8-bit chars (otherwise shows dots)"
default n
depends on VI
help
If your terminal can display characters with high bit set,
you may want to enable this. Note: vi is not Unicode-capable.
If your terminal combines several 8-bit bytes into one character
(as in Unicode mode), this will not work properly.
config FEATURE_VI_COLON
bool "Enable \":\" colon commands (no \"ex\" mode)"
default y
depends on VI
help
Enable a limited set of colon commands for vi. This does not
provide an "ex" mode.
config FEATURE_VI_YANKMARK
bool "Enable yank/put commands and mark cmds"
default y
depends on VI
help
This will enable you to use yank and put, as well as mark in
busybox vi.
config FEATURE_VI_SEARCH
bool "Enable search and replace cmds"
default y
depends on VI
help
Select this if you wish to be able to do search and replace in
busybox vi.
config FEATURE_VI_USE_SIGNALS
bool "Catch signals"
default y
depends on VI
help
Selecting this option will make busybox vi signal aware. This will
make busybox vi support SIGWINCH to deal with Window Changes, catch
Ctrl-Z and Ctrl-C and alarms.
config FEATURE_VI_DOT_CMD
bool "Remember previous cmd and \".\" cmd"
default y
depends on VI
help
Make busybox vi remember the last command and be able to repeat it.
config FEATURE_VI_READONLY
bool "Enable -R option and \"view\" mode"
default y
depends on VI
help
Enable the read-only command line option, which allows the user to
open a file in read-only mode.
config FEATURE_VI_SETOPTS
bool "Enable set-able options, ai ic showmatch"
default y
depends on VI
help
Enable the editor to set some (ai, ic, showmatch) options.
config FEATURE_VI_SET
bool "Support for :set"
default y
depends on VI
help
Support for ":set".
config FEATURE_VI_WIN_RESIZE
bool "Handle window resize"
default y
depends on VI
help
Make busybox vi behave nicely with terminals that get resized.
config FEATURE_VI_ASK_TERMINAL
bool "Use 'tell me cursor position' ESC sequence to measure window"
default y
depends on VI
help
If terminal size can't be retrieved and $LINES/$COLUMNS are not set,
this option makes vi perform a last-ditch effort to find it:
vi positions cursor to 999,999 and asks terminal to report real
cursor position using "ESC [ 6 n" escape sequence, then reads stdin.
This is not clean but helps a lot on serial lines and such.
config FEATURE_VI_OPTIMIZE_CURSOR
bool "Optimize cursor movement"
default y
depends on VI
help
This will make the cursor movement faster, but requires more memory
and it makes the applet a tiny bit larger.
config FEATURE_ALLOW_EXEC
bool "Allow vi and awk to execute shell commands"
default y
