config BUSYBOX_PATCH
bool "patch"
depends on !BUSYBOX_DISABLE_PATCH
default n
help
Apply a unified diff formatted patch.
config BUSYBOX_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 BUSYBOX_FEATURE_VI_MAX_LEN
int "Maximum screen width in vi"
range 256 16384
default 4096
depends on BUSYBOX_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 BUSYBOX_FEATURE_VI_8BIT
bool "Allow vi to display 8-bit chars (otherwise shows dots)"
default n
depends on BUSYBOX_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 BUSYBOX_FEATURE_VI_COLON
bool "Enable \":\" colon commands (no \"ex\" mode)"
default y
depends on BUSYBOX_VI
help
Enable a limited set of colon commands for vi. This does not
provide an "ex" mode.
config BUSYBOX_FEATURE_VI_YANKMARK
bool "Enable yank/put commands and mark cmds"
default y
depends on BUSYBOX_VI
help
This will enable you to use yank and put, as well as mark in
busybox vi.
config BUSYBOX_FEATURE_VI_SEARCH
bool "Enable search and replace cmds"
default y
depends on BUSYBOX_VI
help
Select this if you wish to be able to do search and replace in
busybox vi.
config BUSYBOX_FEATURE_VI_REGEX_SEARCH
bool "Enable regex in search and replace"
default n # Uses GNU regex, which may be unavailable. FIXME
depends on BUSYBOX_FEATURE_VI_SEARCH
help
Use extended regex search.
config BUSYBOX_FEATURE_VI_USE_SIGNALS
bool "Catch signals"
default y
depends on BUSYBOX_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 BUSYBOX_FEATURE_VI_DOT_CMD
bool "Remember previous cmd and \".\" cmd"
default y
depends on BUSYBOX_VI
help
Make busybox vi remember the last command and be able to repeat it.
config BUSYBOX_FEATURE_VI_READONLY
bool "Enable -R option and \"view\" mode"
default y
depends on BUSYBOX_VI
help
Enable the read-only command line option, which allows the user to
open a file in read-only mode.
config BUSYBOX_FEATURE_VI_SETOPTS
bool "Enable set-able options, ai ic showmatch"
default y
depends on BUSYBOX_VI
help
Enable the editor to set some (ai, ic, showmatch) options.
config BUSYBOX_FEATURE_VI_SET
bool "Support for :set"
default y
depends on BUSYBOX_VI
help
Support for ":set".
config BUSYBOX_FEATURE_VI_WIN_RESIZE
bool "Handle window resize"
default y
depends on BUSYBOX_VI
help
Make busybox vi behave nicely with terminals that get resized.
config BUSYBOX_FEATURE_VI_ASK_TERMINAL
bool "Use 'tell me cursor position' ESC sequence to measure window"
default y
depends on BUSYBOX_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:
position cursor to 999,999 and ask terminal to report real
cursor position using "ESC [ 6 n" escape sequence, then read stdin.
This is not clean but helps a lot on serial lines and such.
config BUSYBOX_FEATURE_VI_UNDO
bool "Support undo command 'u'"
default y
depends on BUSYBOX_VI
help
Support the 'u' command to undo insertion, deletion, and replacement
of text.
config BUSYBOX_FEATURE_VI_UNDO_QUEUE
bool "Enable undo operation queuing"
default y
depends on BUSYBOX_FEATURE_VI_UNDO
help
The vi undo functions can use an intermediate queue to greatly lower
malloc() calls and overhead. When the maximum size of this queue is
reached, the contents of the queue are committed to the undo stack.
This increases the size of the undo code and allows some undo
operations (especially un-typing/backspacing) to be far more useful.
config BUSYBOX_FEATURE_VI_UNDO_QUEUE_MAX
int "Maximum undo character queue size"
default 256
range 32 65536
depends on BUSYBOX_FEATURE_VI_UNDO_QUEUE
help
This option sets the number of bytes used at runtime for the queue.
Smaller values will create more undo objects and reduce the amount
of typed or backspaced characters that are grouped into one undo
operation; larger values increase the potential size of each undo
and will generally malloc() larger objects and less frequently.
Unless you want more (or less) frequent "undo points" while typing,
you should probably leave this unchanged.
config BUSYBOX_AWK
bool "awk"
default y
help
Awk is used as a pattern scanning and processing language. This is
the BusyBox implementation of that programming language.
config BUSYBOX_FEATURE_AWK_LIBM
bool "Enable math functions (requires libm)"
default y
depends on BUSYBOX_AWK
help
Enable math functions of the Awk programming language.
NOTE: This will require libm to be present for linking.
config BUSYBOX_FEATURE_AWK_GNU_EXTENSIONS
bool "Enable a few GNU extensions"
default y
depends on BUSYBOX_AWK
help
Enable a few features from gawk:
* command line option -e AWK_PROGRAM
* simultaneous use of -f and -e on the command line.
This enables the use of awk library files.
Ex: awk -f mylib.awk -e '{print myfunction($1);}' ...
config BUSYBOX_CMP
bool "cmp"
default y
help
cmp is used to compare two files and returns the result
to standard output.
config BUSYBOX_DIFF
bool "diff"
depends on !BUSYBOX_DISABLE_DIFF
default y
help
diff compares two files or directories and outputs the
differences between them in a form that can be given to
the patch command.
config BUSYBOX_FEATURE_DIFF_LONG_OPTIONS
bool "Enable long options"
default y
depends on BUSYBOX_DIFF && BUSYBOX_LONG_OPTS
help
Enable use of long options.
config BUSYBOX_FEATURE_DIFF_DIR
bool "Enable directory support"
default y
depends on BUSYBOX_DIFF
help
This option enables support for directory and subdirectory
comparison.
config BUSYBOX_ED
bool "ed"
depends on !BUSYBOX_DISABLE_ED
default y
help
The original 1970's Unix text editor, from the days of teletypes.
Small, simple, evil. Part of SUSv3. If you're not already using
this, you don't need it.
config BUSYBOX_SED
bool "sed"
depends on !BUSYBOX_DISABLE_SED
default y
help
sed is used to perform text transformations on a file
or input from a pipeline.
config BUSYBOX_FEATURE_ALLOW_EXEC
bool "Allow vi and awk to execute shell commands"
default y
depends on BUSYBOX_VI || BUSYBOX_AWK
help
Enables vi and awk features which allows user to execute
shell commands (using system() C call).
