14 Awk is used as a pattern scanning and processing language. This is
15 the BusyBox implementation of that programming language.
17 config FEATURE_AWK_LIBM
18 bool "Enable math functions (requires libm)"
22 Enable math functions of the Awk programming language.
23 NOTE: This will require libm to be present for linking.
29 cmp is used to compare two files and returns the result
36 diff compares two files or directories and outputs the
37 differences between them in a form that can be given to
40 config FEATURE_DIFF_LONG_OPTIONS
41 bool "Enable long options"
43 depends on DIFF && LONG_OPTS
45 Enable use of long options.
47 config FEATURE_DIFF_DIR
48 bool "Enable directory support"
52 This option enables support for directory and subdirectory
59 The original 1970's Unix text editor, from the days of teletypes.
60 Small, simple, evil. Part of SUSv3. If you're not already using
61 this, you don't need it.
67 sed is used to perform text transformations on a file
68 or input from a pipeline.
74 'vi' is a text editor. More specifically, it is the One True
75 text editor <grin>. It does, however, have a rather steep
76 learning curve. If you are not already comfortable with 'vi'
77 you may wish to use something else.
79 config FEATURE_VI_MAX_LEN
80 int "Maximum screen width in vi"
85 Contrary to what you may think, this is not eating much.
86 Make it smaller than 4k only if you are very limited on memory.
88 config FEATURE_VI_8BIT
89 bool "Allow vi to display 8-bit chars (otherwise shows dots)"
93 If your terminal can display characters with high bit set,
94 you may want to enable this. Note: vi is not Unicode-capable.
95 If your terminal combines several 8-bit bytes into one character
96 (as in Unicode mode), this will not work properly.
98 config FEATURE_VI_COLON
99 bool "Enable \":\" colon commands (no \"ex\" mode)"
103 Enable a limited set of colon commands for vi. This does not
104 provide an "ex" mode.
106 config FEATURE_VI_YANKMARK
107 bool "Enable yank/put commands and mark cmds"
111 This will enable you to use yank and put, as well as mark in
114 config FEATURE_VI_SEARCH
115 bool "Enable search and replace cmds"
119 Select this if you wish to be able to do search and replace in
122 config FEATURE_VI_USE_SIGNALS
127 Selecting this option will make busybox vi signal aware. This will
128 make busybox vi support SIGWINCH to deal with Window Changes, catch
129 Ctrl-Z and Ctrl-C and alarms.
131 config FEATURE_VI_DOT_CMD
132 bool "Remember previous cmd and \".\" cmd"
136 Make busybox vi remember the last command and be able to repeat it.
138 config FEATURE_VI_READONLY
139 bool "Enable -R option and \"view\" mode"
143 Enable the read-only command line option, which allows the user to
144 open a file in read-only mode.
146 config FEATURE_VI_SETOPTS
147 bool "Enable set-able options, ai ic showmatch"
151 Enable the editor to set some (ai, ic, showmatch) options.
153 config FEATURE_VI_SET
154 bool "Support for :set"
160 config FEATURE_VI_WIN_RESIZE
161 bool "Handle window resize"
165 Make busybox vi behave nicely with terminals that get resized.
167 config FEATURE_VI_ASK_TERMINAL
168 bool "Use 'tell me cursor position' ESC sequence to measure window"
172 If terminal size can't be retrieved and $LINES/$COLUMNS are not set,
173 this option makes vi perform a last-ditch effort to find it:
174 vi positions cursor to 999,999 and asks terminal to report real
175 cursor position using "ESC [ 6 n" escape sequence, then reads stdin.
177 This is not clean but helps a lot on serial lines and such.
179 config FEATURE_VI_OPTIMIZE_CURSOR
180 bool "Optimize cursor movement"
184 This will make the cursor movement faster, but requires more memory
185 and it makes the applet a tiny bit larger.
187 config FEATURE_ALLOW_EXEC
188 bool "Allow vi and awk to execute shell commands"
192 Enables vi and awk features which allows user to execute
193 shell commands (using system() C call).
