Date: Thu, 05 Jul 2007 14:02:33 -0700 From: Sam Lantinga Subject: SDL 1.3 keyboard plan After lots of discussion with Christian, this is what we came up with: > So, to sum up... > SDLK_* become the physical keys, starting at > (1<<21) > We create a macro SDLK_INDEX(X) > We have two functions SDL_GetLayoutKey(SDLKey) and SDL_GetKeyName() > SDL_GetLayoutKey maps to UCS4 for printable characters, and SDLK* for non-printable characters > and does so based on the OS's current keyboard layout > SDL_GetKeyName() handles both SDLK_* and UCS4, converting UCS4 to UTF-8 and converting SDLK_* into our names, which are UTF-8 for printable characters. > WASD folks use SDLK_*, and 'I' folks use SDL_GetLayoutKey(SDLK_*) Here is the patch he came up with, and his e-mail about it: Date: Fri, 17 Aug 2007 19:50:28 +0200 From: Christian Walther Subject: Re: SDL 1.3 keyboard plan > Sounds great, go ahead and send me a patch. Here goes! Thanks for having a look. Don't hesitate to comment if anything does not conform to your ideas. One caveat: Committing this now may break compilability of some video drivers - specifically, if they use any of the SDLK_* codes that were obsoleted and moved into SDL_compat.h. I only tried Cocoa (which did break, but is already fixed) and X11 (which didn't, but then its key handling is #iffed out). If that's a problem, it may need to go into a branch. -Christian

/**
 * \typedef SDLKey
 *
 * \brief The SDL virtual key representation.
 *
 * Values of this type are used to represent keyboard keys, among other places
 * in the \link SDL_keysym::sym key.keysym.sym \endlink field of the SDL_Event
 * structure.
 *
 * There are two fundamental ways of referring to a key: First, a certain code
 * can stand for a key at a specific physical location on the keyboard,
 * independent of its label or what character it generates. These are the \e
 * physical key codes, comparable to the raw hardware scancodes that a keyboard
 * generates. Second, a code can refer to a key with a specific label,
 * generating a specific character or performing a specific function, which may
 * be located at different places on the keyboard, or not exist at all,
 * depending on what keyboard layout is used. These are \e layout key codes.
 *
 * There is a certain overlap between the sets of physical key codes and layout
 * key codes: \e return, \e tab, \e ctrl etc. are typically independent of the
 * keyboard layout and can be thought of as either a physical or a layout key.
 * Therefore, rather than having separate types with separate sets of constants
 * for physical keys and layout keys, a single type ::SDLKey is used for both
 * sets. The physical key codes (forming a well-known set of a few hundred
 * elements) are enumerated in enum ::SDLPhysicalKey. The set of layout key
 * codes is more diverse: For keys that don't generate characters, the layout
 * key code is equal to the physical key code, i.e. the same SDLK_* constants
 * from enum ::SDLPhysicalKey are used. For character keys, the layout key code
 * is equal to the Unicode code point of the character that is generated when
 * the key is pressed without shift or any other modifiers (for ASCII
 * characters, this can be directly written as a character literal like
 * <tt>'x'</tt>).
 *
 * The \link SDL_keysym::sym key.keysym.sym \endlink field of the SDL_Event
 * structure is always a physical key code. To get the layout key code for the
 * event, run that physical key code through SDL_GetLayoutKey(), which converts
 * it to a layout key code according to the current keyboard layout settings of
 * the OS. In particular, this is what should be done when displaying the name
 * of a key to the user: use
 * <tt>SDL_GetKeyName(SDL_GetLayoutKey(myPhysicalKeyCode))</tt>. Do not use
 * SDL_GetKeyName() directly on a physical key code (except for debugging
 * purposes), as the name returned by that will not correspond to how the key
 * is labeled on the user's keyboard.
 *
 * \par Example:
 * To implement WASD directional keys, it makes sense to use physical key
 * codes, so that the "forward" key will be above the "backward" key even
 * though, for example, it's labeled "Z", not "W", on a French keyboard:
 * \code
 * print("To go forward, press the %s key.", SDL_GetKeyName(SDL_GetLayoutKey(SDLK_W)));
 * ...
 * switch (event.key.keysym.sym) {
 *     case SDLK_W:
 *         forward();
 *         break;
 *     case SDLK_A:
 *         left();
 *         break;
 *     ...
 * }
 * \endcode
 * For keys based on mnemonics like "I for inventory" or "Z for zoom", use
 * layout key codes, so that the key labeled "Z" will zoom, whether it's at the
 * bottom left of the keyboard like on a US layout, or in the upper center like
 * on a German layout (but keep in mind that this forces your users to use a
 * keyboard layout where there \e is an I or Z key):
 * \code
 * print("To open the inventory, press the %s key.", SDL_GetKeyName('i'));
 * ...
 * switch (SDL_GetLayoutKey(event.key.keysym.sym)) {
 *     case 'i':
 *         inventory();
 *         break;
 *     case 'z':
 *         zoom();
 *         break;
 *     ...
 * }
 * \endcode
 * Of course, in a real application, you should not hardcode your key
 * assignments like this, but make them user-configurable.

/**
 * \brief SDL physical key codes.
 *
 * This is the set of physical key codes, i.e. the values of SDL_keysym::sym.
 * Some of them (those for non-character keys) also appear as layout key codes.
 * The constants are typically named after how the key would be labeled on a US
 * keyboard, e.g. SDLK_A or SDLK_LEFTBRACKET refer to the keys used as A and [
 * on a US layout, but used as Q and ^ on a French layout.
 *
 * <em>enum SDLPhysicalKey</em> is not a useful type in its own right - the
 * constants defined here are intended as values of the ::SDLKey type. The only
 * reason for the enum to have a name at all is that otherwise it would be
 * impossible to refer to it in the documentation.
 *
 * \sa SDLKey
 *
 * \par Notes for driver implementors:
 * These constants and their numerical values are based on the USB HID usage
 * tables, version 1.12
 * <http://www.usb.org/developers/devclass_docs/Hut1_12.pdf>, section "10
 * Keyboard/Keypad Page (0x07)". When deciding what code to generate for what
 * key, the following rules can be used as guidelines:
 * - A given key on a given keyboard should produce the same SDLK_* code, no
 * matter what computer it is connected to, what OS runs on that computer, and
 * what the keyboard layout settings in the OS are. For USB keyboards, that
 * should be the code numerically corresponding to the key's USB usage code
 * (with exceptions, see comments for specific constants).
 * - Two keys on two different keyboards are considered "the same key" and
 * should generate the same SDLK_* code if, when connected to the same
 * computer, they are treated equally by the OS. For USB keyboards, that's
 * generally the case when they generate the same USB usage code. Non-USB
 * keyboards can probably be treated like USB keyboards of the same layout, if
 * such exist. If not, and there's no possibility to determine the equivalence
 * relation by transitivity from the above - in particular, on devices like
 * phones or game consoles that don't have PC-style alphabetic keyboards -
 * apply common sense. If none of the predefined codes fit, insert new ones at
 * the end.
