		27	=head1 RXVT-UNICODE VS. RXVT
		28
		29	Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
		30	internally. That means it can store and display most scripts in the
		31	world. Being a terminal emulator, however, some things are very difficult,
		32	especially cursive scripts such as arabic, vertically written scripts
		33	like mongolian or scripts requiring extremely complex combining rules,
		34	like tibetan or devanagari. Don't expect pretty output when using these
		35	scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
		36	fine, though. A somewhat difficult case are right-to-left scripts, such
		37	as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
		38	belong in the application, not the terminal emulator (too many things --
		39	such as cursor-movement while editing -- break otherwise), but that might
		40	change.
		41
		42	If you are looking for a terminal that supports more exotic scripts, let
		43	me recommend C<mlterm>, which is a very user friendly, lean and clean
		44	terminal emulator. In fact, the reason rxvt-unicode was born was solely
		45	because the author couldn't get C<mlterm> to use one font for latin1 and
		46	another for japanese.
		47
		48	Therefore another design rationale was the use of multiple fonts to
		49	display characters: The idea of a single unicode font which many other
		50	programs force onto its users never made sense to me: You should be able
		51	to choose any font for any script freely.
		52
		53	Apart from that, rxvt-unicode is also much better internationalised than
		54	its predecessor, supports things such as XFT and ISO 14755 that are handy
		55	in i18n-environments, is faster, and has a lot bugs less than the original
		56	rxvt. This all in addition to dozens of other small improvements.
		57
		58	It is still faithfully following the original rxvt idea of being lean
		59	and nice on resources: for example, you can still configure rxvt-unicode
		60	without most of its features to get a lean binary. It also comes with
		61	a client/daemon pair that lets you open any number of terminal windows
		62	from within a single process, which makes startup time very fast and
		63	drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
		64	@@RXVT_NAME@@c(1) (client).
		65
		66	It also makes technical information about escape sequences (which have
		67	been extended) more accessible: see @@RXVT_NAME@@(7) for technical
		68	reference documentation (escape sequences etc.).

		484	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		485	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		486	quite a bit, so don't expect it to keep some specific state. It's best to
		487	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		488
		489	The window will not be destroyed when @@RXVT_NAME@@ exits.
		490
		491	It might be useful to know that @@RXVT_NAME@@ will not close file
		492	descriptors passed to it (except for stdin/out/err, of course), so you
		493	can use file descriptors to communicate with the programs within the
		494	terminal. This works regardless of whether the C<-embed> option was used or
		495	not.
		496
		497	Here is a short Gtk2-perl snippet that illustrates how this option can be
		498	used (a longer example is in F<doc/embed>):
		499
		500	my $rxvt = new Gtk2::Socket;
		501	$rxvt->signal_connect_after (realize => sub {
		502	my $xid = $_[0]->window->get_xid;

		507
		508	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		509	pair but instead use the given file descriptor as the tty master. This is
		510	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		511	without having to run a program within it.
		512
		513	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		514	entries and will not tinker with pty/tty permissions - you have to do that
		515	yourself if you want that.
		516
		517	As an extremely special case, specifying C<-1> will completely suppress
		518	pty/tty operations, which is probably only useful in conjunction with some
		519	perl extension that manages the terminal.
		520
		521	Here is a example in perl that illustrates how this option can be used (a
		522	longer example is in F<doc/pty-fd>):

		524	use IO::Pty;
		525	use Fcntl;
		526

702	KEYSYM_RESOURCE.	1174	The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
		1175	any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
		1176	B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
		1177	and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
		1178	B<2>, B<3>, B<4>, B<5>.
		1179
		1180	The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
		1181	whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
		1182	keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
		1183	current application keymap mode state.
		1184
		1185	The spellings of I<key> can be obtained by using B<xev>(1) command or
		1186	searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
		1187	omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
		1188	keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
		1189	performed in an exact manner; however, the closest match is assured.
		1190
		1191	I<string> may contain escape values (C<\n>: newline, C<\000>: octal
		1192	number), see RESOURCES in C<man 7 X> for further details.
		1193
		1194	You can define a range of keysyms in one shot by
		1195	loading the C<keysym-list> perl extension and providing a I<string>
		1196	with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
		1197	should be a character not used by the strings.
		1198
		1199	Its usage can be demonstrated by an example:
		1200
		1201	URxvt.keysym.M-C-0x61: list|\033<|abc|>
		1202
		1203	The above line is equivalent to the following three lines:
		1204
		1205	URxvt.keysym.Meta-Control-0x61: \033<a>
		1206	URxvt.keysym.Meta-Control-0x62: \033<b>
		1207	URxvt.keysym.Meta-Control-0x63: \033<c>
		1208
		1209	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1210	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1211	example the following means "change the current locale to C<zh_CN.GBK>
		1212	when Control-Meta-c is being pressed":
		1213
		1214	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1215
		1216	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1217	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1218	manpage. For example, the F<selection> extension (activated via
		1219	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1220
		1221	URxvt.keysym.M-C-c: perl:selection:rot13
		1222
		1223	Due the the large number of modifier combinations, a defined key mapping
		1224	will match if I<at least> the specified identifiers are being set, and
		1225	no other key mappings with those and more bits are being defined. That
		1226	means that defining a key map for C<a> will automatically provide
		1227	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1228	mappings themselves.
		1229
		1230	Unfortunately, this will override built-in key mappings. For example
		1231	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1232	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1233	user-defined keymap using the C<builtin:> replacement:
		1234
		1235	URxvt.keysym.Insert: <my insert key sequence>
		1236	URxvt.keysym.S-Insert: builtin:
		1237
		1238	The first line defines a mapping for C<Insert> and I<any> combination
		1239	of modifiers. The second line re-establishes the default mapping for
		1240	C<Shift-Insert>.
		1241
		1242	The following example will map Control-Meta-1 and Control-Meta-2 to
		1243	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1244	font-switching at runtime:
		1245
		1246	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1247	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1248
		1249	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1250	info):
		1251
		1252	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1265	example, C<default,-selection> will use all the default extension except
		1266	C<selection>.
		1267
		1268	Extension names can also be followed by an argument in angle brackets

		1417
		1418	=item * 5.1: Basic method
		1419
		1420	This allows you to enter unicode characters using their hexcode.
		1421
		1422	Start by pressing and holding both C<Control> and C<Shift>, then enter
		1423	hex-digits (between one and six). Releasing C<Control> and C<Shift> will
		1424	commit the character as if it were typed directly. While holding down
		1425	C<Control> and C<Shift> you can also enter multiple characters by pressing
		1426	C<Space>, which will commit the current character and lets you start a new
		1427	one.
		1428
		1429	As an example of use, imagine a business card with a japanese e-mail
		1430	address, which you cannot type. Fortunately, the card has the e-mail
		1431	address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
		1432	by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
		1433	followed by releasing the modifier keys.
		1434
		1435	=item * 5.2: Keyboard symbols entry method
		1436
		1437	This mode lets you input characters representing the keycap symbols of
		1438	your keyboard, if representable in the current locale encoding.
		1439
		1440	Start by pressing C<Control> and C<Shift> together, then releasing
		1441	them. The next special key (cursor keys, home etc.) you enter will not
		1442	invoke its usual function but instead will insert the corresponding
		1443	keycap symbol. The symbol will only be entered when the key has been
		1444	released, otherwise pressing e.g. C<Shift> would enter the symbol for
		1445	C<ISO Level 2 Switch>, although your intention might have been to enter a
		1446	reverse tab (Shift-Tab).
		1447
		1448	=item * 5.3: Screen-selection entry method
		1449
		1450	While this is implemented already (it's basically the selection
		1451	mechanism), it could be extended by displaying a unicode character map.
		1452
		1453	=item * 5.4: Feedback method for identifying displayed characters for later input
		1454
		1455	This method lets you display the unicode character code associated with
		1456	characters already displayed.
		1457
		1458	You enter this mode by holding down C<Control> and C<Shift> together, then
		1459	pressing and holding the left mouse button and moving around. The unicode
		1460	hex code(s) (it might be a combining character) of the character under the
		1461	pointer is displayed until you release C<Control> and C<Shift>.
		1462
		1463	In addition to the hex codes it will display the font used to draw this
		1464	character - due to implementation reasons, characters combined with
		1465	combining characters, line drawing characters and unknown characters will
		1466	always be drawn using the built-in support font.

		1542	@@RXVT_NAME@@ -fg Black -bg White -rv
		1543
		1544	would yield White on Black, while on I<xterm>(1) it would yield Black on
		1545	White.
		1546
		1547	=head2 ALPHA CHANNEL SUPPORT
		1548
		1549	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1550	their act together, rxvt-unicode will do its own alpha channel management:
		1551
		1552	You can prefix any colour with an opaqueness percentage enclosed in
		1553	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1554	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1555	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1556	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1557	is the recommended format to specify transparency values, and works with
		1558	all ways to specify a colour.
		1559
		1560	For complete control, rxvt-unicode also supports
		1561	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1562	specifications, where the additional C<aaaa> component specifies opacity
		1563	(alpha) values. The minimum value of C<0000> is completely transparent,
		1564	while C<ffff> is completely opaque). The two example colours from
		1565	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1566	C<rgba:0000/ff00/0000/f332>.
		1567
		1568	You probably need to specify B<"-depth 32">, too, to force a visual with
		1569	alpha channels, and have the luck that your X-server uses ARGB pixel
		1570	layout, as X is far from just supporting ARGB visuals out of the box, and
		1571	rxvt-unicode just fudges around.
		1572
		1573	For example, the following selects an almost completely transparent black
		1574	background, and an almost opaque pink foreground:
		1575
		1576	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1577
		1578	When not using a background image, then the interpretation of the
		1579	alpha channel is up to your compositing manager (most interpret it as
		1580	transparency of course).
		1581
		1582	When using a background pixmap or pseudo-transparency, then the background
		1583	colour will always behave as if it were completely transparent (so the
		1584	background image shows instead), regardless of how it was specified, while
		1585	other colours will either be transparent as specified (the background
		1586	image will show through) on servers supporting the RENDER extension, or
		1587	fully opaque on servers not supporting the RENDER EXTENSION.
		1588
		1589	Please note that due to bugs in Xft, specifying alpha values might result
		1590	in garbage being displayed when the X-server does not support the RENDER
		1591	extension.
