		502
		503	Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
		504	shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
		505	quite a bit, so don't expect it to keep some specific state. It's best to
		506	create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
		507
		508	The window will not be destroyed when @@RXVT_NAME@@ exits.
		509
		510	It might be useful to know that @@RXVT_NAME@@ will not close file
		511	descriptors passed to it (except for stdin/out/err, of course), so you
		512	can use file descriptors to communicate with the programs within the
		513	terminal. This works regardless of whether the C<-embed> option was used or
		514	not.
		515
		516	Here is a short Gtk2-perl snippet that illustrates how this option can be
		517	used (a longer example is in F<doc/embed>):
		518
		519	my $rxvt = new Gtk2::Socket;
		520	$rxvt->signal_connect_after (realize => sub {
		521	my $xid = $_[0]->window->get_xid;

		526
		527	Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
		528	pair but instead use the given file descriptor as the tty master. This is
		529	useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
		530	without having to run a program within it.
		531
		532	If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
		533	entries and will not tinker with pty/tty permissions - you have to do that
		534	yourself if you want that.
		535
		536	As an extremely special case, specifying C<-1> will completely suppress
		537	pty/tty operations, which is probably only useful in conjunction with some
		538	perl extension that manages the terminal.
		539
		540	Here is a example in perl that illustrates how this option can be used (a
		541	longer example is in F<doc/pty-fd>):
		542
		543	use IO::Pty;
		544	use Fcntl;
		545
		546	my $pty = new IO::Pty;

		1182
		1183	If I<string> takes the form of C<command:STRING>, the specified B<STRING>
		1184	is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
		1185	example the following means "change the current locale to C<zh_CN.GBK>
		1186	when Control-Meta-c is being pressed":
		1187
		1188	URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
		1189
		1190	If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
		1191	is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
		1192	manpage. For example, the F<selection> extension (activated via
		1193	C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
		1194
		1195	URxvt.keysym.M-C-c: perl:selection:rot13
		1196
		1197	Due the the large number of modifier combinations, a defined key mapping
		1198	will match if I<at least> the specified identifiers are being set, and
		1199	no other key mappings with those and more bits are being defined. That
		1200	means that defining a key map for C<a> will automatically provide
		1201	definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
		1202	mappings themselves.
		1203
		1204	Unfortunately, this will override built-in key mappings. For example
		1205	if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
		1206	C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
		1207	user-defined keymap using the C<builtin:> replacement:
		1208
		1209	URxvt.keysym.Insert: <my insert key sequence>
		1210	URxvt.keysym.S-Insert: builtin:
		1211
		1212	The first line defines a mapping for C<Insert> and I<any> combination
		1213	of modifiers. The second line re-establishes the default mapping for
		1214	C<Shift-Insert>.
		1215
		1216	The following example will map Control-Meta-1 and Control-Meta-2 to
		1217	the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
		1218	font-switching at runtime:
		1219
		1220	URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
		1221	URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
		1222
		1223	Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
		1224	info):
		1225
		1226	URxvt.keysym.M-C-3: command:\033[8;25;80t

		1237	them. This can be useful to selectively disable some extensions loaded
		1238	by default, or specified via the C<perl-ext-common> resource. For
		1239	example, C<default,-selection> will use all the default extension except
		1240	C<selection>.
		1241
		1242	Extension names can also be followed by an argument in angle brackets
		1243	(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for

		1521	=head2 ALPHA CHANNEL SUPPORT
		1522
		1523	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1524	their act together, rxvt-unicode will do it's own alpha channel management:
		1525
		1526	You can prefix any colour with an opaqueness percentage enclosed in
		1527	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1528	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1529	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1530	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1531	is the recommended format to specify transparency values, and works with
		1532	all ways to specify a colour.
		1533
		1534	For complete control, rxvt-unicode also supports
		1535	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1536	specifications, where the additional C<aaaa> component specifies opacity
		1537	(alpha) values. The minimum value of C<0000> is completely transparent,
		1538	while C<ffff> is completely opaque). The two example colours from
		1539	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1540	C<rgba:0000/ff00/0000/f332>.
		1541
		1542	You probably need to specify B<"-depth 32">, too, to force a visual with
		1543	alpha channels, and have the luck that your X-server uses ARGB pixel
		1544	layout, as X is far from just supporting ARGB visuals out of the box, and
		1545	rxvt-unicode just fudges around.
		1546
		1547	For example, the following selects an almost completely transparent black
		1548	background, and an almost opaque pink foreground:
		1549
		1550	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1551
		1552	When not using a background image, then the interpretation of the
		1553	alpha channel is up to your compositing manager (most interpret it as
		1554	transparency of course).
		1555
		1556	When using a background pixmap or pseudo-transparency, then the background
		1557	colour will always behave as if it were completely transparent (so the

997	=item When I log-in to another system it tells me about missing terminfo data?
998
999	The terminal description used by rxvt-unicode is not as widely available
1000	as that for xterm, or even rxvt (for which the same problem often arises).
1001
1002	The correct solution for this problem is to install the terminfo, this can be done
1003	like this:
1004
1005	infocmp rxvt-unicode >rxvt.unicode.tic
1006	scp rxvt-unicode.tic remotesystem:
1007	ssh remotesystem tic rxvt-unicode.tic
1008
1009	... or by installing rxvt-unicode normally on the remote system,
1010
1011	If you cannot or do not want to do this, then you can simply set
1012	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
1013	problems arising, which includes wrong keymapping, less and different
1014	colours and some refresh errors in fullscreen applications. It's a nice
1015	quick-and-dirty workaround for rare cases, though.
1016
1017	If you always want to do this you can either recompile rxvt-unicode with
1018	the desired TERM value or use a resource to set it:
1019
1020	URxvt.termName: rxvt
1021
1022	=item How can I configure rxvt-unicode so that it looks similar to the original rxvt?
1023
1024	Felix von Leitner says that these two lines, in your F<.Xdefaults>, will make rxvt-unicode
1025	behave similar to the original rxvt:
1026
1027	URxvt.font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1
1028	URxvt.boldFont: -misc-fixed-bold-r-semicondensed--13-120-75-75-c-60-iso8859-1
1029
1030	=item Rxvt-unicode does not seem to understand the selected encoding?
1031
1032	=item Unicode does not seem to work?
1033
1034	If you encounter strange problems like typing an accented character but
1035	getting two unrelated other characters or similar, or if program output is
1036	subtly garbled, then you should check your locale settings.
1037
1038	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
1039	programs. Often rxvt-unicode is started in the C<C> locale, while the
1040	login script running within the rxvt-unicode window changes the locale to
1041	sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
1042
1043	The best thing is to fix your startup environment, as you will likely run
1044	into other problems. If nothing works you can try this in your .profile.
1045
1046	printf '\e]701;%s\007' "$LC_CTYPE"
1047
1048	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
1049	supported on your systems. Some systems have a C<locale> comamnd which
1050	displays this. If it displays sth. like:
1051
1052	locale: Cannot set LC_CTYPE to default locale: ...
1053
1054	Then the locale you specified is not supported on your system.
1055
1056	If nothing works and you are sure that everything is set correctly then
1057	you will need to remember a little known fact: Some programs just don't
1058	support locales :(
1059
1060	=item Why do the characters look ugly?
1061
1062	=item How does rxvt-unicode choose fonts?
1063
1064	Most fonts do not contain the full range of Unicode, which is
1065	fine. Chances are that the font you (or the admin/package maintainer of
1066	your system/os) have specified does not cover all the characters you want
1067	to display.
1068
1069	B<rxvt-unicode> makes a best-effort try at finding a replacement
1070	font. Often the result is fine, but sometimes the chosen font looks
1071	bad. Many fonts have totally strange characters that don't resemble the
1072	correct glyph at all, and rxvt-unicode lacks the artificial intelligence
1073	to detetc that a specific glyph is wrong: it has to believe the font that
1074	the characters it contains indeed look correct.
1075
1076	In that case, select a font of your taste and add it to the font list,
1077	e.g.:
1078
1079	@@RXVT_NAME@@ -fn basefont,font2,font3...
1080
1081	When rxvt-unicode sees a character, it will first look at the base
1082	font. If the base font does not contain the character, it will go to the
1083	next font, and so on. Specifying your own fonts will also speed up this
1084	search and use less resources within rxvt-unicode and the X-server.
1085
1086	The only limitation is that all the fonts must not be larger than the base
1087	font, as the base font defines the principial cell size, which must be the
1088	same due to the way terminals work.
1089
1090	=item Why do some chinese characters look so different than others?
1091
1092	This is because there is a difference between script and language --
1093	rxvt-unicode does not know which language the text that is output
1094	is, as it only knows the unicode character codes. If rxvt-unicode
1095	first sees a japanese character, it might choose a japanese font for
1096	it. Subseqzuent japanese characters will take that font. Now, many chinese
1097	characters aren't represented in japanese fonts, so when the first
1098	non-japanese character comes up, rxvt-unicode will look for a chinese font
1099	-- unfortunately at this point, it will still use the japanese font for
1100	japanese characters that are also chinese.
1101
1102	The workaround is easy: just tag a chinese font at the end of your font
1103	list (see the previous question). The key is to view the font list as
1104	a preference list: If you expect more japanese, list a japanese font
1105	first. If you expect more chinese, put a chinese font first.
1106
1107	In the future it might be possible to switch preferences at runtime (the
1108	internal data structure has no problem with using different fonts for
1109	the same character at the same time, but no interface for this has been
1110	designed yet).
1111
1112	=item How can I keep rxvt-unicode from using reverse video so much?
1113
1114	First of all, make sure you are running with the right terminfo
1115	(C<urxvt>), which will get rid of most of these effects. Then make sure
1116	you have specified colours for italic and bold, as otherwise rxvt-unicode
1117	might use reverse video to simulate the effect:
1118
1119	URxvt*colorBD: white
1120	URxvt*colorIT: green
1121
1122	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
1123
1124	For some unexplainable reason, some programs (i.e. irssi) assume a very
1125	weird colour palette when confronted with a terminal with more than the
1126	standard 8 colours (rxvt-unicode supports 88). The right fix is, of
1127	course, to fix these programs not to assume non-ISO colours without very
1128	good reasons.
1129
1130	In the meantime, you can either edit your C<urxvt> terminfo definition to
1131	only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
1132	but keep you from using other rxvt-unicode features.
1133
1134	=item How does rxvt-unicode determine the encoding to use?
1135
1136	=item Is there an option to switch encodings?
1137
1138	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1139	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1140	UTF-8 or any other encodings with respect to terminal I/O.
1141
1142	The reasons is that there exists a perfectly fine mechanism for selecting
1143	the encoding, doing I/O and (most important) communicating this to all
1144	applications so everybody agrees on character properties such as width and
1145	code number. This mechanism is the I<locale>.
1146
1147	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1148	programs doing the same (that is, most) will automatically agree in the
1149	interpretation of characters.
1150
1151	Unfortunately, there is no system-independent way to select locales, nor
1152	is there a standard on how locale specifiers will look like.
1153
1154	On most systems, the content of the C<LC_CTYPE> environment variable
1155	contains an arbitrary string which corresponds to an already-installed
1156	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1157	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1158	(i.e. C<de> or C<german>) are also common.
1159
1160	Rxvt-unicode ignores all other locale categories, and except for
1161	the encoding, ignores country or language-specific settings,
1162	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1163
1164	If you want to use a specific encoding you have to make sure you start
1165	rxvt-unicode with the correct C<LC_CTYPE> category.
1166
1167	=item Can I switch locales at runtime?
1168
1169	Yes, using an escape sequence. Try sth. like this, which sets
1170	rxvt-unicode's idea of C<LC_CTYPE>.
1171
1172	printf '\e]701;%s\007' ja_JP.SJIS
1173
1174	See also the previous question.
1175
1176	Sometimes this capability is rather handy when you want to work in one
1177	locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1178	example, I use this script to start C<xjdic>, which first switches to a
1179	locale supported by xjdic and back later:
1180
1181	printf '\e]701;%s\007' ja_JP.SJIS
1182	xjdic -js
1183	printf '\e]701;%s\007' de_DE.UTF-8
1184
1185	=item Can I switch the fonts at runtime?
1186
1187	Yes, using an escape sequence. Try sth. like this, which has the same
1188	effect as using the C<-fn> switch, and takes effect immediately:
1189
1190	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1191
1192	This is useful if you e.g. work primarily with japanese (and prefer a
1193	japanese font), but you have to switch to chinese temporarily, where
1194	japanese fonts would only be in your way.
1195
1196	You can think of this as a kind of manual ISO-2022 switching.
1197
1198	=item Why do italic characters look as if clipped?
1199
1200	Many fonts have difficulties with italic characters and hinting. For
1201	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
1202	Mono> completely fails in it's italic face. A workaround is to enable
1203	freetype autohinting, i.e. like this:
1204
1205	URxvt*italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
1206	URxvt*boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
1207
1208	=item My input method wants <some encoding> but I want UTF-8, what can I do?
1209
1210	You cna specify separate locales for the input method and the rest of the
1211	terminal, using the resource C<imlocale>:
1212
1213	URxvt*imlocale: ja_JP.EUC-JP
1214
1215	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1216	use your input method. Please note, however, that you will not be able to
1217	input characters outside C<EUC-JP> in a normal way then, as your input
1218	method limits you.
1219
1220	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
1221
1222	Rxvt-unicode tries to obey the rule of not charging you for sth. you
1223	don't use. One thing you should try is to configure out all settings that
1224	you don't need, for example, Xft support is a resource hog by design,
1225	when used. Compiling it out ensures that no Xft font will be loaded
1226	accidentally when rxvt-unicode tries to find a font for your characters.
1227
1228	Also, many people (me included) like large windows and even larger
1229	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
1230	6 bytes per screen cell. For a 160x?? window this amounts to almost a
1231	kilobyte per line. A scorllback buffer of 10000 lines will then (if full)
1232	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
1233	rxvt-unicode then uses 8 bytes per screen cell.
1234
1235	=item Can I speed up Xft rendering somehow?
1236
1237	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
1238	it is simply slow. If you still want Xft fonts you might try to disable
1239	antialiasing (by appending C<:antialiasing=false>), which saves lots of
1240	memory and also speeds up rendering considerably.
1241
1242	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
1243
1244	Rxvt-unicode will use whatever you specify as a font. If it needs to
1245	fall back to it's default font search list it will prefer X11 core
1246	fonts, because they are small and fast, and then use Xft fonts. It has
1247	antialiaisng disabled for most of them, because the author thinks they
1248	look best that way.
1249
1250	If you want antialiasing, you have to specify the fonts manually.
1251
1252	=item Mouse cut/paste suddenly no longer works.
1253
1254	Make sure that mouse reporting is actually turned off since killing
1255	some editors prematurely may leave the mouse in mouse report mode. I've
1256	heard that tcsh may use mouse reporting unless it otherwise specified. A
1257	quick check is to see if cut/paste works when the Alt or Shift keys are
1258	depressed. See @@RXVT_NAME@@(7)
1259
1260	=item What's with this bold/blink stuff?
1261
1262	If no bold colour is set via C<colorBD:>, bold will invert text using the
1263	standard foreground colour.
1264
1265	For the standard background colour, blinking will actually make the
1266	text blink when compiled with C<--enable-blinking>. with standard
1267	colours. Without C<--enable-blinking>, the blink attribute will be
1268	ignored.
1269
1270	On ANSI colours, bold/blink attributes are used to set high-intensity
1271	foreground/background colors.
1272
1273	color0-7 are the low-intensity colors.
1274
1275	color8-15 are the corresponding high-intensity colors.
1276
1277	=item I don't like the screen colors. How do I change them?
1278
1279	You can change the screen colors at run-time using F<~/.Xdefaults>
1280	resources (or as long-options).
1281
1282	Here are values that are supposed to resemble a VGA screen,
1283	including the murky brown that passes for low-intensity yellow:
1284
1285	Rxvt*color0: #000000
1286	Rxvt*color1: #A80000
1287	Rxvt*color2: #00A800

1300	Rxvt*color14: #00FFFF
1301	Rxvt*color15: #FFFFFF
1302
1303	=item What's with the strange Backspace/Delete key behaviour?
1304
1305	Assuming that the physical Backspace key corresponds to the
1306	BackSpace keysym (not likely for Linux ... see the following
1307	question) there are two standard values that can be used for
1308	Backspace: C<^H> and C<^?>.
1309
1310	Historically, either value is correct, but rxvt-unicode adopts the debian
1311	policy of using C<^?> when unsure, because it's the one only only correct
1312	choice :).
1313
1314	Rxvt-unicode tries to inherit the current stty settings and uses the value
1315	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1316	started from a terminal (say, from a menu or by remote shell), then the
1317	system value of `erase', which corresponds to CERASE in <termios.h>, will
1318	be used (which may not be the same as your stty setting).
1319
1320	For starting a new rxvt-unicode:
1321
1322	# use Backspace = ^H
1323	$ stty erase ^H
1324	$ @@RXVT_NAME@@
1325
1326	# use Backspace = ^?
1327	$ stty erase ^?
1328	$ @@RXVT_NAME@@
1329
1330	Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1331
1332	For an existing rxvt-unicode:
1333
1334	# use Backspace = ^H
1335	$ stty erase ^H
1336	$ echo -n "^[[36h"
1337
1338	# use Backspace = ^?
1339	$ stty erase ^?
1340	$ echo -n "^[[36l"
1341
1342	This helps satisfy some of the Backspace discrepancies that occur, but
1343	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1344	properly reflects that.
1345
1346	The Delete key is a another casualty of the ill-defined Backspace problem.
1347	To avoid confusion between the Backspace and Delete keys, the Delete
1348	key has been assigned an escape sequence to match the vt100 for Execute
1349	(ESC[3~) and is in the supplied termcap/terminfo.
1350
1351	Some other Backspace problems:
1352
1353	some editors use termcap/terminfo,
1354	some editors (vim I'm told) expect Backspace = ^H,
1355	GNU Emacs (and Emacs-like editors) use ^H for help.
1356
1357	Perhaps someday this will all be resolved in a consistent manner.
1358
1359	=item I don't like the key-bindings. How do I change them?

1361	There are some compile-time selections available via configure. Unless
1362	you have run "configure" with the C<--disable-resources> option you can
1363	use the `keysym' resource to alter the keystrings associated with keysym
1364	0xFF00 - 0xFFFF (function, cursor keys, etc).

1407	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1408	How do I make use of them? For example, the Sun Keyboard type 4
1409	has the following mappings that rxvt-unicode doesn't recognize.
1410
1411	KP_Insert == Insert
1412	F22 == Print
1413	F27 == Home
1414	F29 == Prior
1415	F33 == End
1416	F35 == Next
1417
1418	Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1419	mappings, it is better to use `xmodmap' to remap the keys as required for
1420	your particular machine.
1421
1422	=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1423	I need this to decide about setting colors etc.
1424
1425	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1426	check and see if that is set. Note that several programs, JED, slrn,
1427	Midnight Commander automatically check this variable to decide whether or
1428	not to use color.
1429
1430	=item How do I set the correct, full IP address for the DISPLAY variable?
1431
1432	If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1433	insecure mode then it is possible to use the following shell script
1434	snippets to correctly set the display. If your version of rxvt-unicode
1435	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1436	the COLORTERM variable can be used to distinguish rxvt-unicode from a
1437	regular xterm.
1438
1439	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
1440	snippets:
1441
1442	# Bourne/Korn/POSIX family of shells:
1443	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
1444	if [ ${TERM:-foo} = xterm ]; then
1445	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
1446	echo -n '^[Z'
1447	read term_id
1448	stty icanon echo
1449	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
1450	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
1451	read DISPLAY # set it in our local shell
1452	fi
1453	fi
1454
1455	=item How do I compile the manual pages for myself?
1456
1457	You need to have a recent version of perl installed as F</usr/bin/perl>,
1458	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
1459	the doc subdirectory and enter C<make alldoc>.
