# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Editors" config AWK bool "awk" default n help Awk is used as a pattern scanning and processing language. This is the BusyBox implementation of that programming language. config FEATURE_AWK_MATH bool "Enable math functions (requires libm)" default y depends on AWK help Enable math functions of the Awk programming language. NOTE: This will require libm to be present for linking. config CMP bool "cmp" default n help cmp is used to compare two files and returns the result to standard output. config DIFF bool "diff" default n 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 FEATURE_DIFF_BINARY bool "Enable checks for binary files" default y depends on DIFF help This option enables support for checking for binary files before a comparison is carried out. config FEATURE_DIFF_DIR bool "Enable directory support" default y depends on DIFF help This option enables support for directory and subdirectory comparison. config FEATURE_DIFF_MINIMAL bool "Enable -d option to find smaller sets of changes" default n depends on DIFF help Enabling this option allows the use of -d to make diff try hard to find the smallest possible set of changes. config ED bool "ed" default n 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 PATCH bool "patch" default n help Apply a unified diff formatted patch. config SED bool "sed" default n help sed is used to perform text transformations on a file or input from a pipeline. config VI bool "vi" default n help 'vi' is a text editor. More specifically, it is the One True text editor . 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 line length in vi" range 256 16384 default 1024 depends on VI help vi uses on-stack buffers for intermediate line buffers. You may want to decrease this parameter if your target machine benefits from smaller stack usage. 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_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 depends on VI || AWK help Enables vi and awk features which allows user to execute shell commands (using system() C call). endmenu
