13 Awk is used as a pattern scanning and processing language.
15 config BUSYBOX_FEATURE_AWK_LIBM
16 bool "Enable math functions (requires libm)"
18 depends on BUSYBOX_AWK
20 Enable math functions of the Awk programming language.
21 NOTE: This requires libm to be present for linking.
23 config BUSYBOX_FEATURE_AWK_GNU_EXTENSIONS
24 bool "Enable a few GNU extensions"
26 depends on BUSYBOX_AWK
28 Enable a few features from gawk:
29 * command line option -e AWK_PROGRAM
30 * simultaneous use of -f and -e on the command line.
31 This enables the use of awk library files.
32 Example: awk -f mylib.awk -e '{print myfunction($1);}' ...
37 cmp is used to compare two files and returns the result
43 diff compares two files or directories and outputs the
44 differences between them in a form that can be given to
47 config BUSYBOX_FEATURE_DIFF_LONG_OPTIONS
48 bool "Enable long options"
50 depends on BUSYBOX_DIFF && BUSYBOX_LONG_OPTS
52 config BUSYBOX_FEATURE_DIFF_DIR
53 bool "Enable directory support"
55 depends on BUSYBOX_DIFF
57 This option enables support for directory and subdirectory
63 The original 1970's Unix text editor, from the days of teletypes.
64 Small, simple, evil. Part of SUSv3. If you're not already using
65 this, you don't need it.
70 Apply a unified diff formatted patch.
75 sed is used to perform text transformations on a file
76 or input from a pipeline.
81 'vi' is a text editor. More specifically, it is the One True
82 text editor <grin>. It does, however, have a rather steep
83 learning curve. If you are not already comfortable with 'vi'
84 you may wish to use something else.
86 config BUSYBOX_FEATURE_VI_MAX_LEN
87 int "Maximum screen width"
92 Contrary to what you may think, this is not eating much.
93 Make it smaller than 4k only if you are very limited on memory.
95 config BUSYBOX_FEATURE_VI_8BIT
96 bool "Allow to display 8-bit chars (otherwise shows dots)"
100 If your terminal can display characters with high bit set,
101 you may want to enable this. Note: vi is not Unicode-capable.
102 If your terminal combines several 8-bit bytes into one character
103 (as in Unicode mode), this will not work properly.
105 config BUSYBOX_FEATURE_VI_COLON
106 bool "Enable \":\" colon commands (no \"ex\" mode)"
108 depends on BUSYBOX_VI
110 Enable a limited set of colon commands. This does not
111 provide an "ex" mode.
113 config BUSYBOX_FEATURE_VI_COLON_EXPAND
114 bool "Expand \"%\" and \"#\" in colon commands"
116 depends on BUSYBOX_FEATURE_VI_COLON
118 Expand the special characters \"%\" (current filename)
119 and \"#\" (alternate filename) in colon commands.
121 config BUSYBOX_FEATURE_VI_YANKMARK
122 bool "Enable yank/put commands and mark cmds"
124 depends on BUSYBOX_VI
126 This enables you to use yank and put, as well as mark.
128 config BUSYBOX_FEATURE_VI_SEARCH
129 bool "Enable search and replace cmds"
131 depends on BUSYBOX_VI
133 Select this if you wish to be able to do search and replace.
135 config BUSYBOX_FEATURE_VI_REGEX_SEARCH
136 bool "Enable regex in search and replace"
137 default n # Uses GNU regex, which may be unavailable. FIXME
138 depends on BUSYBOX_FEATURE_VI_SEARCH
140 Use extended regex search.
142 config BUSYBOX_FEATURE_VI_USE_SIGNALS
145 depends on BUSYBOX_VI
147 Selecting this option will make vi signal aware. This will support
148 SIGWINCH to deal with Window Changes, catch ^Z and ^C and alarms.
150 config BUSYBOX_FEATURE_VI_DOT_CMD
151 bool "Remember previous cmd and \".\" cmd"
153 depends on BUSYBOX_VI
155 Make vi remember the last command and be able to repeat it.
157 config BUSYBOX_FEATURE_VI_READONLY
158 bool "Enable -R option and \"view\" mode"
160 depends on BUSYBOX_VI
162 Enable the read-only command line option, which allows the user to
163 open a file in read-only mode.
165 config BUSYBOX_FEATURE_VI_SETOPTS
166 bool "Enable settable options, ai ic showmatch"
168 depends on BUSYBOX_VI
170 Enable the editor to set some (ai, ic, showmatch) options.
172 config BUSYBOX_FEATURE_VI_SET
175 depends on BUSYBOX_VI
177 config BUSYBOX_FEATURE_VI_WIN_RESIZE
178 bool "Handle window resize"
180 depends on BUSYBOX_VI
182 Behave nicely with terminals that get resized.
184 config BUSYBOX_FEATURE_VI_ASK_TERMINAL
185 bool "Use 'tell me cursor position' ESC sequence to measure window"
187 depends on BUSYBOX_VI
189 If terminal size can't be retrieved and $LINES/$COLUMNS are not set,
190 this option makes vi perform a last-ditch effort to find it:
191 position cursor to 999,999 and ask terminal to report real
192 cursor position using "ESC [ 6 n" escape sequence, then read stdin.
193 This is not clean but helps a lot on serial lines and such.
195 config BUSYBOX_FEATURE_VI_UNDO
196 bool "Support undo command \"u\""
198 depends on BUSYBOX_VI
200 Support the 'u' command to undo insertion, deletion, and replacement
203 config BUSYBOX_FEATURE_VI_UNDO_QUEUE
204 bool "Enable undo operation queuing"
206 depends on BUSYBOX_FEATURE_VI_UNDO
208 The vi undo functions can use an intermediate queue to greatly lower
209 malloc() calls and overhead. When the maximum size of this queue is
210 reached, the contents of the queue are committed to the undo stack.
211 This increases the size of the undo code and allows some undo
212 operations (especially un-typing/backspacing) to be far more useful.
214 config BUSYBOX_FEATURE_VI_UNDO_QUEUE_MAX
215 int "Maximum undo character queue size"
218 depends on BUSYBOX_FEATURE_VI_UNDO_QUEUE
220 This option sets the number of bytes used at runtime for the queue.
221 Smaller values will create more undo objects and reduce the amount
222 of typed or backspaced characters that are grouped into one undo
223 operation; larger values increase the potential size of each undo
224 and will generally malloc() larger objects and less frequently.
225 Unless you want more (or less) frequent "undo points" while typing,
226 you should probably leave this unchanged.
228 config BUSYBOX_FEATURE_VI_VERBOSE_STATUS
229 bool "Enable verbose status reporting"
231 depends on BUSYBOX_VI
233 Enable more verbose reporting of the results of yank, change,
234 delete, undo and substitution commands.
236 config BUSYBOX_FEATURE_ALLOW_EXEC
237 bool "Allow vi and awk to execute shell commands"
239 depends on BUSYBOX_VI || BUSYBOX_AWK
241 Enables vi and awk features which allow user to execute
242 shell commands (using system() C call).
