-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.

-"between different configurations.\n"
-"\n"
-"At the end of the main menu you will find two options. One is\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"
