Overview +----------- + +The code usually consists of many stages. + + * Configuring the menusytem + * Installing global handlers [optional] + * Populating the menusystem + * Executing the menusystem + * Processing the result + +1.1 Configuring the menusystem +------------------------------ +This includes setting the window the menu system should use, +the choice of colors, the title of the menu etc. In most functions +calls, a value of -1 indicates that the default value be used. +For details about what the arguments are look at function +declarations in menu.h + +<code> + // Choose the default title and setup default values for all attributes.... + init_menusystem(NULL); + set_window_size(1,1,23,78); // Leave one row/col border all around + + // Choose the default values for all attributes and char's + // -1 means choose defaults (Actually the next 4 lines are not needed) + set_normal_attr (-1,-1,-1,-1); + set_status_info (-1,-1); + set_title_info (-1,-1); + set_misc_info(-1,-1,-1,-1); +</code> + +1.2 Populating the menusystem +----------------------------- +This involves adding a menu to the system, and the options which +should appear in the menu. An example is given below. + +<code> + MAINMENU = add_menu(" Menu Title ",-1); + CHECKED = 1; + add_item("option1","Status 1",OPT_RUN,"kernel1 arg1=val1",0); + add_item("selfloop","Status 2",OPT_SUBMENU,NULL,MAINMENU); + add_item("othermenu","Status 3",OPT_SUBMENU,"menuname",0); + add_sep(); + add_item("checkbox,"Checkbox Info",OPT_CHECKBOX,NULL,CHECKED); + add_item("Exit ","Status String",OPT_EXITMENU,NULL,0); +</code> + +The call to add_menu has two arguments, the first being the title of +the menu and the second an upper bound on the number of items in the menu. +Putting a -1, will use the default (see MENUSIZE in menu.h). If you try +to add more items than specified, the extra items will not appear in +the menu. The accuracy of this number affects the memory required +to run the system. + +If you do not want to keep track of the return values, you can also use +the following variant of add_menu + +<code> +add_named_menu("main"," Menu Title ",-1) +</code> + +This creates a new menu as before and gives it a name "main". When using named +menus, you get an alternate way for adding submenu's. See below for details. + +The call to add_item has five arguments. +The first argument is the text which appears in the menu itself. +The second argument is the text displayed in the status line. +The third argument indicates the type of this menuitem. It is one of +the following + + * OPT_RUN : executable content + * OPT_EXITMENU : exits menu to parent + * OPT_SUBMENU : if selected, displays a submenu + * OPT_CHECKBOX : associates a boolean with this item which can be toggled + * OPT_RADIOMENU: associates this with a radio menu. + After execution, the data field of this item will point + to the option selected. + * OPT_SEP : A menu seperator (visually divide menu into parts) + * OPT_RADIOITEM: this item is one of the options in a RADIOMENU + * OPT_INACTIVE : A disabled item (user cannot select this) + * OPT_INVISIBLE: This item will not be displayed. + +The fourth argument is the value of the data field always a string. +Usually this string is just copied and nothing is done with it. Two +cases, where it is used. + +In case of a radiomenu the input string is ignored and the "data" field +points to the menuitem chosen (Dont forget to typecast this pointer to +(t_menuitem *) when reading this info). + +In case of a submenu, this string if non-trivial is interpreted as the +name of the submenu which should be linked there. This interpretation +happens when the menu is first run and not when the menu system is being +created. This allows the user to create the menusystem in an arbitrary +order. + + +The fifth argument is a number whose meaning depends on the type of the +item. For a CHECKBOX it should be 0/1 setting the initial state of the +checkbox. For a SUBMENU it should be the index of the menu which should +be displayed if this option is chosen. Incase the data field is non-trivial, +this number is ignored and computed later. For a RADIOMENU it should be the +index of the menu which contains all the options (All items in that menu +not of type RADIOITEM are ignored). For all other types, this +argument has no meaning at all. + +A call to add_sep is a convenient shorthand for calling add_item +with the type set to OPT_SEP. + +1.3 Executing the menusystem +---------------------------- +This is the simplest of all. Just call showmenus, with the index +of the main menu as its argument. It returns a pointer to the menu +item which was selected by the user. + +<code> + choice = showmenus(MAIN); // Initial menu is the one with index MAIN + // or choice = showmenus(find_menu_num("main")); // Initial menu is the one named "main" +</code> + +1.4 Processing the result +------------------------- +This pointer will either be NULL (user hit Escape) or always point +to a menuitem which can be "executed", i.e. it will be of type OPT_RUN. +Usually at this point, all we need to do is to ask syslinux to run +the command associated with this menuitem. The following code executes +the command stored in choice->data (there is no other use for the data +field, except for radiomenu's) + +<code> + if (choice) + { + if (choice->action == OPT_RUN) + { + if (syslinux) runcommand(choice->data); + else csprint(choice->data,0x07); + return 1; + } + csprint("Error in programming!",0x07); + } +</code> + +2. Advanced features +-------------------- +Everycall to add_item actually returns a pointer to the menuitem +created. This can be useful when using any of the advanced features. + +2.1 extra_data +-------------- +For example, every menuitem has an "extra_data" field (a pointer) +which the user can use to point any data he/she pleases. The menusystem +itself does not use this field in anyway. + +2.2 helpid +---------- +Every item also has a field called "helpid". It is meant to hold some +kind of identifier which can be referenced and used to generate +a context sensitive help system. This can be set after a call to +add_item as follows +<code> + add_item("selfloop","Status 2",OPT_SUBMENU,NULL,MAINMENU); + set_item_options('A',4516); +</code> + +The first is the shortcut key for this entry. You can put -1 to ensure +that the shortcut key is not reset. The second is some unsigned integer. +If this value is 0xFFFF, then the helpid is not changed. + +2.3 Installing global handlers +------------------------------ +It is possible to register handlers for the menu system. These are +user functions which are called by the menusystem in certain +situations. Usually the handlers get a pointer to the menusystem +datastructure as well as a pointer to the current item selected. +Some handlers may get additional information. Some handlers are +required to return values while others are not required to do so. + +Currently the menusystem support three types of global handlers +* timeout handler +* screen handler +* keys handler + +2.3.1 timeout handler +--------------------- +This is installed using a call to "reg_ontimeout(fn,numsteps,stepsize)" +function. fn is a pointer to a function which takes no arguments and +returns one of CODE_WAIT, CODE_ENTER, CODE_ESCAPE. This function is +called when numsteps*stepsize Centiseconds have gone by without any +user input. If the function returns CODE_WAIT then the menusystem +waits for user input (for another numsteps*stepsize Centiseconds). If +CODE_ENTER or CODE_ESCAPE is returned, then the system pretends that +the user hit ENTER or ESCAPE on the keyboard and acts accordingly. + +2.3.2 Screen handler +-------------------- +This is installed using a call to "reg_handler(HDLR_SCREEN,fn)". fn is +a pointer to a function which takes a pointer to the menusystem +datastructure and the current item selected and returns nothing. +This is called everytime a menu is drawn (i.e. everytime user changes +the current selection). This is meant for displaying any additional +information which reflects the current state of the system. + +2.3.3 Keys handler +------------------ +This is installed using a call to "reg_handler(HDLR_KEYS,fn)". fn is +a pointer to a function which takes a pointer to the menusystem +datastructure, the current item and the scan code of a key and returns +nothing. This function is called when the user presses a key which +the menusystem does not know to dealwith. In any case, when this call +returns the screen should not have changed in any way. Usually, +one can change the active page and display any output needed and +reset the active page when you return from this call. + +complex.c implements a key_handler, which implements a simple +context sensitive help system, by displaying the contents of a +file whose name is based on the helpid of the active item. + +Also, complex.c's handler allows certain users to make changes +to edit the commands associated with a menu item. + +2.4 Installing item level handlers +---------------------------------- +In addition to global handlers, one can also install handlers for each +individual item. A handler for an individual item is a function which +takes a pointer to the menusystem datastructure and a pointer to the +current item and return a structure of type t_handler_return. Currently +it has two bit fields "valid" and "refresh". + +This handler is called when the user hits "enter" on a RUN item, or +changes the status of a CHECKBOX, or called *after* a radio menu choice +has been set. In all other cases, installing a handler has no effect. + +The handler can change any of the internal datastructures it pleases. +For e.g. in a radiomenu handler, one can change the text displayed +on the menuitem depending on which choice was selected (see complex.c +for an example). The return values are ignored for RADIOMENU's. + +In case of RUN items: the return values are used as follows. If the +return value of "valid" was false, then this user choice is ignored. +This is useful if the handler has useful side effects. For e.g. +complex.c has a Login item, whose handler always return INVALID. It +sets a global variable to the name of the user logged in, and enables +some menu items, and makes some invisible items visible. + +* If the handler does not change the visibility status of any items, + the handler should set "refresh" to 0. +* If the handler changes the visibility status of items in the current + menu set "refresh" to 1. +* If you are changing the visibility status of items in menu's currently + not displayed, then you can set "refresh" to 0. +* Changing the visibility status of items in another menu + which is currently displayed, is not supported. If you do it, + the screen contents may not reflect the change until you get to the + menu which was changed. When you do get to that menu, you may notice + pieces of the old menu still on the screen. + +In case of CHECKBOXES: the return value of "valid" is ignored. Because, +the handler can change the value of checkbox if the user selected value +is not appropriate. only the value of "refresh" is honored. In this case +all the caveats in the previous paragraph apply. + +menu.h defines two instances of t_handler_return +ACTION_VALID and ACTION_INVALID for common use. These set the valid flag +to 1 and 0 respectively and the refresh flag to 0. + +3. Things to look out for +------------------------- +When you define the menu system, always declare it in the opposite +order, i.e. all lower level menu's should be defined before the higher +level menus. This is because in order to define the MAINMENU, you need +to know the index assigned to all its submenus. + +4. Additional Modules +--------------------- +You can make use of the following additional modules, in writing your +handlers. + +* Passwords +* Help + +4.1 Passwords +------------- +This module was written by Th. Gebhardt. This is basically a modification +of the DES crypt function obtained by removing the dependence of the +original crypt function on C libraries. The following functions are +defined + + init_passwords(PWDFILE) + // Read in the password database from the file + authenticate_user(user,pwd) + // Checks if user,pwd is valid + isallowed(user,perm) + // Checks if the user has a specified permission + close_passwords() + // Unloads password database from memory + + See the sample password file for more details about the file format + and the implementation of permissions. + +See complex.c for a example of how to use this. + +4.2 Help +-------- +This can be used to set up a context sensitive help system. The following +functions are defined + + init_help(HELPBASEDIR) + // Initialises the help system. All help files will be loaded + // from the directory specified. + runhelpsystem(context) + // Displays the contents of HELPBASEDIR/hlp<context>.txt + +In order to have a functioning help system, you just need to create +the hlp<NNNNN>.txt files and initialize the help system by specifying +the base directory. + +The first line of this file assumed to be the title of the help screen. +You can use ^N and ^O to change attributes absolutely and relatively, +i.e. [^O]46 (i.e. Ctrl-O followed by chars 4 and 6) will set the +attribute to 46, while [^N]08 will XOR the current attribute with +specified number, thus in this case the first [^N]08 will turn on +highlighting and the second one will turn it off. diff --git a/contrib/syslinux-4.02/com32/cmenu/MENU_FORMAT b/contrib/syslinux-4.02/com32/cmenu/MENU_FORMAT new file mode 100644 index 0000000..24cb02f --- /dev/null +++ b/contrib/syslinux-4.02/com32/cmenu/MENU_FORMAT @@ -0,0 +1,262 @@ +A .menu file can be used to describe basic menu structures which can be converted +into C code which can then be compiled into a .c32 file for use with SYSLINUX. +The format of a .menu file is similar to an ini file, but with important +differences. + +Lines starting with # and ; are treated as comments.

When a dot command +is executed the system executes all the given "single commands" in the specified order. +All the commands marked "[T]" are terminal commands, i.e. when the system encounters +such a command it stops processing the dot command and returns the terminal command +which caused the termination to the caller (who usually interprets the command +appropriately). + +All commands marked with [NT] are non-terminal commands, i.e. once these commands are +processed the system continues to process the remaining "single commands" specified in +the "DOT COMMAND". + +Note: The case of a syslinux command is tricky. When executed, the command should never return +(if the specified kernel exists) so the fact that we consider it a [NT] should be taken with +a pinch of salt. However, if the syslinux command does return (in case of no kernel), then +remaining "single commands" are processed. In particular "ker1 arg1 % ker2 arg2 % ker3 args" +has the effect of executing the first kernel which exists + +.nop: + Does nothing. +.beep: + .beep [n] produces a beep n times. n must be between 0 and 9. If not specified n=1. + (hence .beep 0 is equivalent to .nop) +.help: + .help <file> + Displays the help file <file> which is assumed to be in the "help" directory. Its name + does not have to be in the form "hlpNNNNN.txt" (as required by the context sensitive help). + Executing this command will mean the appropriate help screen is displayed till the user hits + ESCAPE + +The meaning of the Terminal commands can vary with the context in which it is used. For example, +a ".enter" or ".escape" does not have any meaning in the "onerrorcmd" context but it has a meaning +in the "ontimeout" context.

You can use either simple.c or complex.c as a starting point +for your own menu configuration file; If your menu system is only going +to have entries corresponding to things which can be executed directly, +then you can create a file in ".menu" format instead of the C code. + +See MENU_FORMAT for the syntax of .menu files + +The resulting code is a 32-bit COMBOOT code, and hence can be executed +only under syslinux. You can use tools like bochs to help debug your +code. + +Menu Features currently supported are: +* menu items, +* submenus, +* disabled items, +* checkboxes, +* invisible items (useful for dynamic menus), and +* Radio menus, +* Context sensitive help +* Authenticated users +* Editing commands associated with items + +The keys used are: + +* Arrow Keys, PgUp, PgDn, Home, End Keys +* Space to switch state of a checkbox +* Enter to choose the item +* Escape to exit from it +* Shortcut keys + +Features +-------- +This is a general purpose menu system implemented using only BIOS calls, +so it can be executed in a COMBOOT environment as well. It is highly +customizable. Some features include: + +* Status line + Display any help information associated with each menu item. +* Window + Specify a window within which the menu system draws all its menu's. + It is upto the user to ensure that the menu's fit within the window. +* Positioning submenus + By default, each submenu is positioned just below the corresponding + entry of the parent menu. However, the user may position each menu + at a specific location of his choice. This is useful, when the menu's + have lots of options. +* Registering handlers for each menu item + This is mainly used for checkboxes and radiomenu's, where a selection may + result in disabling other menu items/checkboxes +* Global Screen Handler + This is called every time the menu is redrawn. The user can display + additional information (usually outside the window where the menu is + being displayed). See the complex.c for an example, where the global + handler is used to display the choices made so far. +* Global Keys Handler + This is called every time the user presses a key which the menu + system does not understand. This can be used to display context + sensitive help. See complex.c for how to use this hook to implement + a context sensitive help system as well as "On the fly" editing + of commands associated with menus. +* Shortcut Keys + With each item one can register a shortcut key from [A-Za-z0-9]. + Pressing a key within that range, will take you to the next item + with that shortcut key (so you can have multiple items with the + same shortcut key). The default shortcut key for each item, is + the lower case version of the first char of the item in the range + [A-Za-z0-9]. +* Escape Keys + Each item entry can have a substring enclosed in < and >. This part + is highlighted. Can be used to highlight the shortcut keys. By default + if an item has a <, then the first char inside < and > in the range + [A-Za-z0-9] is converted to lower case and set as the shortcut key. +* Ontimeout handler + The user can register an ontimeout handler, which gets called if + no key has been pressed for a user specific amount of time (default 5 min). + For an example see the complex.c file. + +Credits +------- +* The Watcom developers and Peter Anvin for figuring out an OS + independent startup code. +* Thomas for porting the crypt function and removing all C library + dependencies +* Peter Anvin for porting the code to GCC + +- Murali (gmurali+guicd@cs.uchicago.edu) diff --git a/contrib/syslinux-4.02/com32/cmenu/TODO b/contrib/syslinux-4.02/com32/cmenu/TODO new file mode 100644 index 0000000..d2ee82c --- /dev/null +++ b/contrib/syslinux-4.02/com32/cmenu/TODO @@ -0,0 +1,2 @@ +* Write COMBOOT code to read .menu files and parse them directly + - take the name of menu file to parse from commandline diff --git a/contrib/syslinux-4.02/com32/cmenu/adv_menu.tpl b/contrib/syslinux-4.02/com32/cmenu/adv_menu.tpl new file mode 100644 index 0000000..871c782 --- /dev/null +++ b/contrib/syslinux-4.02/com32/cmenu/adv_menu.tpl @@ -0,0 +1,465 @@ +All the lines in this file not in between --something BEGINS-- and --something ENDS-- +is ignored completely and will not make it into the generated C file + +This file has sections of C code each section delimited by --secname BEGINS-- +and --secname ENDS--.
