Introduction
------------
The configuration database is collection of configuration options
organized in a tree structure:
+- Code maturity level options
| +- Prompt for development and/or incomplete code/drivers
+- General setup
| +- Networking support
| +- System V IPC
| +- BSD Process Accounting
| +- Sysctl support
+- Loadable module support
| +- Enable loadable module support
| +- Set version information on all module symbols
| +- Kernel module loader
+- ...
Every entry has its own dependencies. These dependencies are used
to determine the visible of an entry. Any child entry is only
visible if its parent entry is also visible.
Menu entries
------------
Most entries define a config option, all other entries help to organize
them. A single configuration option is defined like this:
config MODVERSIONS
bool "Set version information on all module symbols"
depends MODULES
help
Usually, modules have to be recompiled whenever you switch to a new
kernel. ...
Every line starts with a key word and can be followed by multiple
arguments. "config" starts a new config entry. The following lines
define attributes for this config option. Attributes can be the type of
the config option, input prompt, dependencies, help text and default
values. A config option can be defined multiple times with the same
name, but every definition can have only a single input prompt and the
type must not conflict.
Menu attributes
---------------
A menu entry can have a number of attributes. Not all of them are
applicable everywhere (see syntax).
- type definition: "bool"/"tristate"/"string"/"hex"/"integer"
Every config option must have a type. There are only two basic types:
tristate and string, the other types base on these two. The type
definition optionally accepts an input prompt, so these two examples
are equivalent:
bool "Networking support"
and
bool
prompt "Networking support"
- input prompt: "prompt" <prompt> ["if" <expr>]
Every menu entry can have at most one prompt, which is used to display
to the user. Optionally dependencies only for this prompt can be added
with "if".
- default value: "default" <symbol> ["if" <expr>]
A config option can have any number of default values. If multiple
default values are visible, only the first defined one is active.
Default values are not limited to the menu entry, where they are
defined, this means the default can be defined somewhere else or be
overridden by an earlier definition.
The default value is only assigned to the config symbol if no other
value was set by the user (via the input prompt above). If an input
prompt is visible the default value is presented to the user and can
be overridden by him.
Optionally dependencies only for this default value can be added with
"if".
- dependencies: "depends on"/"requires" <expr>
This defines a dependency for this menu entry. If multiple
dependencies are defined they are connected with '&&'. Dependencies
are applied to all other options within this menu entry (which also
accept "if" expression), so these two examples are equivalent:
bool "foo" if BAR
default y if BAR
and
depends on BAR
bool "foo"
default y
- help text: "help"
This defines a help text. The end of the help text is determined by
the level indentation, this means it ends at the first line which has
a smaller indentation than the first line of the help text.
Menu dependencies
-----------------
Dependencies define the visibility of a menu entry and can also reduce
the input range of tristate symbols. The tristate logic used in the
expressions uses one more state than normal boolean logic to express the
module state. Dependency expressions have the following syntax:
<expr> ::= <symbol> (1)
<symbol> '=' <symbol> (2)
<symbol> '!=' <symbol> (3)
'(' <expr> ')' (4)
'!' <expr> (5)
<expr> '||' <expr> (6)
<expr> '&&' <expr> (7)
Expressions are listed in decreasing order of precedence.
(1) Convert the symbol into an expression. Boolean and tristate symbols
are simply converted into the respective expression values. All
other symbol types result in 'n'.
(2) If the values of both symbols are equal, it returns 'y',
otherwise 'n'.
(3) If the values of both symbols are equal, it returns 'n',
otherwise 'y'.
(4) Returns the value of the expression. Used to override precedence.
(5) Returns the result of (2-/expr/).
(6) Returns the result of min(/expr/, /expr/).
(7) Returns the result of max(/expr/, /expr/).
An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
respectively for calculations). A menu entry becomes visible when it's
expression evaluates to 'm' or 'y'.
There are two type of symbols: constant and nonconstant symbols.
Nonconstant symbols are the most common ones and are defined with the
'config' statement. Nonconstant symbols consist entirely of alphanumeric
characters or underscores.
Constant symbols are only part of expressions. Constant symbols are
always surrounded by single or double quotes. Within the quote any
other character is allowed and the quotes can be escaped using '\'.
Menu structure
--------------
The position of a menu entry in the tree is determined in two ways. First
it can be specified explicitely:
menu "Network device support"
depends NET
config NETDEVICES
...
endmenu
All entries within the "menu" ... "endmenu" block become a submenu of
"Network device support". All subentries inherit the dependencies from
the menu entry, e.g. this means the dependency "NET" is added to the
dependency list of the config option NETDEVICES.
The other way to generate the menu structure is done by analyzing the
dependencies. If a menu entry somehow depends on the previous entry, it
can be made a submenu of it. First the the previous (parent) symbol must
be part of the dependency list and then one of these two condititions
must be true:
- the child entry must become invisible, if the parent is set to 'n'
- the child entry must only be visible, if the parent is visible
config MODULES
bool "Enable loadable module support"
config MODVERSIONS
bool "Set version information on all module symbols"
depends MODULES
comment "module support disabled"
depends !MODULES
MODVERSIONS directly depends on MODULES, this means it's only visible if
MODULES is different from 'n'. The comment on the other hand is always
visible when MODULES it's visible (the (empty) dependency of MODULES is
also part of the comment dependencies).
Kconfig syntax
--------------
The configuration file describes a series of menu entries, where every
line starts with a keyword (except help texts). The following keywords
end a menu entry:
- config
- choice/endchoice
- comment
- menu/endmenu
- if/endif
- source
The first four also start the definition of a menu entry.
config:
"config" <symbol>
<config options>
This defines a config symbol <symbol> and accepts any of above
attributes as options.
choices:
"choice"
<choice options>
<choice block>
"endchoice"
This defines a choice group and accepts any of above attributes as
options. A choice can only be of type bool or tristate, while a boolean
choice only allows a single config entry to be selected, a tristate
choice also allows any number of config entries to be set to 'm'. This
can be used if multiple drivers for a single hardware exists and only a
single driver can be compiled/loaded into the kernel, but all drivers
can be compiled as modules.
A choice accepts another option "optional", which allows to set the
choice to 'n' and no entry needs to be selected.
comment:
"comment" <prompt>
<comment options>
This defines a comment which is displayed to the user during the
configuration process and is also echoed to the output files. The only
possible options are dependencies.
menu:
"menu" <prompt>
<menu options>
<menu block>
"endmenu"
This defines a menu block, see "Menu structure" above for more
information. The only possible options are dependencies.
if:
"if" <expr>
<if block>
"endif"
This defines an if block. The dependency expression <expr> is appended
to all enclosed menu entries.
source:
"source" <prompt>
This reads the specified configuration file. This file is always parsed.

/*
* Changes by Clifford Wolf (god@clifford.at)
*
* [ 1998-06-13 ]
*
* *) A bugfix for the Page-Down problem
*
* *) Formerly when I used Page Down and Page Up, the cursor would be set
* to the first position in the menu box. Now lxdialog is a bit
* smarter and works more like other menu systems (just have a look at
* it).
*
* *) Formerly if I selected something my scrolling would be broken because
* lxdialog is re-invoked by the Menuconfig shell script, can't
* remember the last scrolling position, and just sets it so that the
* cursor is at the bottom of the box. Now it writes the temporary file
* lxdialog.scrltmp which contains this information. The file is
* deleted by lxdialog if the user leaves a submenu or enters a new
* one, but it would be nice if Menuconfig could make another "rm -f"
* just to be sure. Just try it out - you will recognise a difference!
*
* [ 1998-06-14 ]
*
* *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
* and menus change their size on the fly.
*
* *) If for some reason the last scrolling position is not saved by
* lxdialog, it sets the scrolling so that the selected item is in the
* middle of the menu box, not at the bottom.
*
* 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
* Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
* This fixes a bug in Menuconfig where using ' ' to descend into menus
* would leave mis-synchronized lxdialog.scrltmp files lying around,
* fscanf would read in 'scroll', and eventually that value would get used.

"Overview\n"
"--------\n"
"Some features may be built directly into BusyBox. Some features\n"
"may be completely removed altogether. There are also certain\n"
"parameters which are not really features, but must be\n"
"entered in as decimal or hexadecimal numbers or possibly text.\n"
"\n"
"Menu items beginning with [*] or [ ] represent features\n"
"configured to be built in or removed respectively.\n"
"\n"
"To change any of these features, highlight it with the cursor\n"
"keys and press <Y> to build it in or <N> to removed it.\n"
"You may also press the <Space Bar> to cycle\n"
"through the available options (ie. Y->N->Y).\n"
"\n"
"Some additional keyboard hints:\n"
"\n"
"Menus\n"
"----------\n"
"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
" you wish to change or submenu wish to select and press <Enter>.\n"
" Submenus are designated by \"--->\".\n"
"\n"
" Shortcut: Press the option's highlighted letter (hotkey).\n"
" Pressing a hotkey more than once will sequence\n"
" through all visible items which use that hotkey.\n"
"\n"
" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
" unseen options into view.\n"
"\n"
"o To exit a menu use the cursor keys to highlight the <Exit> button\n"
" and press <ENTER>.\n"
"\n"
" Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
" using those letters. You may press a single <ESC>, but\n"
" there is a delayed response which you may find annoying.\n"
"\n"
" Also, the <TAB> and cursor keys will cycle between <Select>,\n"
" <Exit> and <Help>\n"
"\n"
"o To get help with an item, use the cursor keys to highlight <Help>\n"
" and Press <ENTER>.\n"
"\n"
" Shortcut: Press <H> or <?>.\n"
"\n"
"\n"
"Radiolists (Choice lists)\n"
"-----------\n"
"o Use the cursor keys to select the option you wish to set and press\n"
" <S> or the <SPACE BAR>.\n"
"\n"
" Shortcut: Press the first letter of the option you wish to set then\n"
" press <S> or <SPACE BAR>.\n"
"\n"
"o To see available help for the item, use the cursor keys to highlight\n"
" <Help> and Press <ENTER>.\n"
"\n"
" Shortcut: Press <H> or <?>.\n"
"\n"
" Also, the <TAB> and cursor keys will cycle between <Select> and\n"
" <Help>\n"
"\n"
"\n"
"Data Entry\n"
"-----------\n"
"o Enter the requested information and press <ENTER>\n"
" If you are entering hexadecimal values, it is not necessary to\n"
" add the '0x' prefix to the entry.\n"
"\n"
"o For help, use the <TAB> or cursor keys to highlight the help option\n"
" and press <ENTER>. You can try <TAB><H> as well.\n"
"\n"
"\n"
"Text Box (Help Window)\n"
"--------\n"
"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"
" keys h,j,k,l function here as do <SPACE BAR> and <B> for those\n"
" who are familiar with less and lynx.\n"
"\n"
"o Press <E>, <X>, <Enter> or <Esc><Esc> to exit.\n"
"\n"

"Alternate Configuration Files\n"
"-----------------------------\n"
"Menuconfig supports the use of alternate configuration files for\n"
"those who, for various reasons, find it necessary to switch\n"
"between different configurations.\n"
"\n"
"At the end of the main menu you will find two options. One is\n"
"for saving the current configuration to a file of your choosing.\n"
"The other option is for loading a previously saved alternate\n"
"configuration.\n"
"\n"
"Even if you don't use alternate configuration files, but you\n"
"find during a Menuconfig session that you have completely messed\n"
"up your settings, you may use the \"Load Alternate...\" option to\n"
"restore your previously saved settings from \".config\" without\n"
"restarting Menuconfig.\n"
"\n"
"Other information\n"
"-----------------\n"
"If you use Menuconfig in an XTERM window make sure you have your\n"
"$TERM variable set to point to a xterm definition which supports color.\n"
"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
"display correctly in a RXVT window because rxvt displays only one\n"
"intensity of color, bright.\n"
"\n"
"Menuconfig will display larger menus on screens or xterms which are\n"
"set to display more than the standard 25 row by 80 column geometry.\n"
"In order for this to work, the \"stty size\" command must be able to\n"
"display the screen's current row and column geometry. I STRONGLY\n"
"RECOMMEND that you make sure you do NOT have the shell variables\n"
"LINES and COLUMNS exported into your environment. Some distributions\n"
"export those variables via /etc/profile. Some ncurses programs can\n"
"become confused when those variables (LINES & COLUMNS) don't reflect\n"
"the true screen size.\n"
"\n"
"Optional personality available\n"
"------------------------------\n"
"If you prefer to have all of the options listed in a single\n"
"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
"with MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
"\n"
"make MENUCONFIG_MODE=single_menu menuconfig\n"
"\n"
"<Enter> will then unroll the appropriate category, or enfold it if it\n"
"is already unrolled.\n"
