485Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
486which enables applications to easily embed a terminal.
487
488Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
489shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
490quite a bit, so don't expect it to keep some specific state. It's best to
491create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
492
493The window will not be destroyed when @@RXVT_NAME@@ exits.
494
495It might be useful to know that @@RXVT_NAME@@ will not close file
496descriptors passed to it (except for stdin/out/err, of course), so you
497can use file descriptors to communicate with the programs within the
498terminal. This works regardless of whether the C<-embed> option was used or
499not.
500
501Here is a short Gtk2-perl snippet that illustrates how this option can be
502used (a longer example is in F<doc/embed>):
503
504 my $rxvt = new Gtk2::Socket;
505 $rxvt->signal_connect_after (realize => sub {
506 my $xid = $_[0]->window->get_xid;
507 system "@@RXVT_NAME@@ -embed $xid &";

511
512Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
513pair but instead use the given file descriptor as the tty master. This is
514useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
515without having to run a program within it.
516
517If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
518entries and will not tinker with pty/tty permissions - you have to do that
519yourself if you want that.
520
521As an extremely special case, specifying C<-1> will completely suppress
522pty/tty operations, which is probably only useful in conjunction with some
523perl extension that manages the terminal.
524
525Here is a example in perl that illustrates how this option can be used (a
526longer example is in F<doc/pty-fd>):
527

530
531 my $pty = new IO::Pty;

738omitted. This resource is only available when compiled with 1121
739KEYSYM_RESOURCE. 1122The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1123any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1124B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1125and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1126B<2>, B<3>, B<4>, B<5>.
1127
1128The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1129whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1130keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1131current application keymap mode state.
1132
1133The spellings of I<key> can be obtained by using B<xev>(1) command or
1134searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1135omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1136keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1137performed in an exact manner; however, the closest match is assured.
1138
1139I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1140number), see RESOURCES in C<man 7 X> for futher details.
1141
1142You can define a range of keysyms in one shot by providing a I<string>
1143with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1144should be a character not used by the strings.
1145
1146Its usage can be demonstrated by an example:
1147
1148 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1149
1150The above line is equivalent to the following three lines:
1151
1152 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1153 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1154 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1155
1156If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1157is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1158example the following means "change the current locale to C<zh_CN.GBK>
1159when Control-Meta-c is being pressed":
1160
1161 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1162
1163If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1164is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1165manpage. For example, the F<selection> extension (activated via
1166C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1167
1168 URxvt.keysym.M-C-c: perl:selection:rot13
1169
1170Due the the large number of modifier combinations, a defined key mapping
1171will match if at I<at least> the specified identifiers are being set, and
1172no other key mappings with those and more bits are being defined. That
1173means that defining a key map for C<a> will automatically provide
1174definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1175mappings themselves.
1176
1177Unfortunately, this will override built-in key mappings. For example
1178if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1179C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1180user-defined keymap using the C<builtin:> replacement:
1181
1182 URxvt.keysym.Insert: <my insert key sequence>
1183 URxvt.keysym.S-Insert: builtin:
1184
1185The first line defines a mapping for C<Insert> and I<any> combination
1186of modifiers. The second line re-establishes the default mapping for
1187C<Shift-Insert>.
1188
1189The following example will map Control-Meta-1 and Control-Meta-2 to
1190the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1191font-switching at runtime:
1192
1193 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1194 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1195
1196Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1197info):
1198
1199 URxvt.keysym.M-C-3: command:\033[8;25;80t

1205
1206Comma-separated list(s) of perl extension scripts (default: C<default>) to
1207use in this terminal instance; option B<-pe>.
1208
1209Extension names can be prefixed with a C<-> sign to prohibit using
1210them. This can be useful to selectively disable some extensions loaded
1211by default, or specified via the C<perl-ext-common> resource. For
1212example, C<default,-selection> will use all the default extension except
1213C<selection>.
1214
1215Extension names can also be followed by an argument in angle brackets
1216(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1217searchable scrollback to Alt/Meta-s). Mentioning the same extension
1218multiple times with different arguments will pass multiple arguments to
1219the extension.
1220
1221Each extension is looked up in the library directories, loaded if
1222necessary, and bound to the current terminal instance.
1223
1224If both of these resources are the empty string, then the perl
1225interpreter will not be initialized. The idea behind two options is that
1226B<perl-ext-common> will be used for extensions that should be available to

918=head1 FREQUENTLY ASKED QUESTIONS (FAQ) 1483=head2 ALPHA CHANNEL SUPPORT
1484
1485If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1486their act together, rxvt-unicode will do it's own alpha channel management:
1487
1488You can prefix any color with an opaquenes percentage enclosed in
1489brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1490(0-100) that specifies the opacity of the color, where C<0> is completely
1491transparent and C<100> is completely opaque. For example, C<[50]red> is a
1492half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1493is the recommended format to specify transparency values, and works with
1494all ways to specify a colour.
1495
1496For complete control, rxvt-unicode also supports
1497C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1498specifications, where the additional C<aaaa> component specifies opacity
1499(alpha) values. The minimum value of C<0000> is completely transparent,
1500while C<ffff> is completely opaque). The two example colours from
1501earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1502C<rgba:0000/ff00/0000/f332>.
1503
1504You probably need to specify B<"-depth 32">, too, to force a visual with
1505alpha channels, and have the luck that your X-server uses ARGB pixel
1506layout, as X is far from just supporting ARGB visuals out of the box, and
1507rxvt-unicode just fudges around.
1508
1509For example, the following selects an almost completely transparent black
1510background, and an almost opaque pink foreground:
1511
1512 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1513
1514When not using a background image, then the interpretation of the
1515alpha channel is up to your compositing manager (most interpret it as
1516transparency of course).
1517
1518When using a background pixmap or pseudo-transparency, then the background
1519colour will always behave as if it were completely transparent (so the
1520background image shows instead), regardless of how it was specified, while
1521other colours will either be transparent as specified (the background
1522image will show through) on servers supporting the RENDER extension, or
1523fully opaque on servers not supporting the RENDER EXTENSION.
1524
1525Please note that due to bugs in Xft, specifying alpha values might result
1526in garbage being displayed when the X-server does not support the RENDER
1527extension.

932If you encounter strange problems like typing an accented character but 1547=item B<COLORFGBG>

935 1548

1555and C<slang> can (and do) use this information to optimize screen output.
940 1556
941The best thing is to fix your startup environment, as you will likely run 1557=item B<WINDOWID>

1561window and so on).
945 1562
946If this doesn't work, then maybe you use a C<LC_CTYPE> specification not 1563=item B<TERMINFO>

948displays this. If it displays sth. like:

962Most fonts do not contain the full range of Unicode, which is 1578=item B<RXVT_SOCKET>
963fine. Chances are that the font you (or the admin/package maintainer of
964your system/os) have specified does not cover all the characters you want
965to display.
966 1579
967B<rxvt-unicode> makes a best-effort try at finding a replacement 1580The unix domain socket path used by @@RXVT_NAME@@c(1) and
968font. Often the result is fine, but sometimes the chosen font looks 1581@@RXVT_NAME@@d(1).
969bad. In that case, select a font of your taste and add it to the font
970list, e.g.:
971 1582
972 @@RXVT_NAME@@ -fn basefont,font2,font3... 1583Default F<<< $HOME/.rxvt-unicode-I<< <nodename >> >>>.
973 1584
974When rxvt-unicode sees a character, it will first look at the base 1585=item B<HOME>
975font. If the base font does not contain the character, it will go to the
976next font, and so on.
977 1586
978The only limitation is that all the fonts must not be larger than the base 1587Used to locate the default directory for the unix domain socket for
979font, as the base font defines the principial cell size, which must be the 1588daemon communications and to locate various resource files (such as
980same due to the way terminals work. 1589C<.Xdefaults>)
981 1590
982=item Why do some chinese characters look so different than others? 1591=item B<XAPPLRESDIR>
983 1592
984This is because there is a difference between script and language -- 1593Directory where various X resource files are being located.
985rxvt-unicode does not know which language the text that is output
986is, as it only knows the unicode character codes. If rxvt-unicode
987first sees a japanese character, it might choose a japanese font for
988it. Subseqzuent japanese characters will take that font. Now, many chinese
989characters aren't represented in japanese fonts, so when the first
990non-japanese character comes up, rxvt-unicode will look for a chinese font
991-- unfortunately at this point, it will still use the japanese font for
992japanese characters that are also chinese.
993 1594
994The workaround is easy: just tag a chinese font at the end of your font 1595=item B<XENVIRONMENT>
995list (see the previous question). The key is to view the font list as
996a preference list: If you expect more japanese, list a japanese font
997first. If you expect more chinese, put a chinese font first.
998 1596
999In the future it might be possible to switch preferences at runtime (the 1597If set and accessible, gives the name of a X resource file to be loaded by
1000internal data structure has no problem with using different fonts for
1001the same character at the same time, but no interface for this has been
1002designed yet).
1003
1004=item How does rxvt-unicode determine the encoding to use?
1005
1006=item Is there an option to switch encodings?
1007
1008Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1009specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1010UTF-8 or any other encodings with respect to terminal I/O.
1011
1012The reasons is that there exists a perfectly fine mechanism for selecting
1013the encoding, doing I/O and (most important) communicating this to all
1014applications so everybody agrees on character properties such as width and
1015code number. This mechanism is the I<locale>.
1016
1017Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1018programs doing the same (that is, most) will automatically agree in the
1019interpretation of characters.
1020
1021Unfortunately, there is no system-independent way to select locales, nor
1022is there a standard on how locale specifiers will look like.
1023
1024On most systems, the content of the C<LC_CTYPE> environment variable
1025contains an arbitrary string which corresponds to an already-installed
1026locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1027C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1028(i.e. C<de> or C<german>) are also common.
1029
1030Rxvt-unicode ignores all other locale categories, and except for
1031the encoding, ignores country or language-specific settings,
1032i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1033
1034If you want to use a specific encoding you have to make sure you start
1035rxvt-unicode with the correct C<LC_CTYPE> category.
1036
1037=item Can I switch locales at runtime?
1038
1039Yes, using an escape sequence. Try sth. like this, which sets
1040rxvt-unicode's idea of C<LC_CTYPE>.
1041
1042 printf '\e]701;%s\007' ja_JP.SJIS
1043
1044See also the previous question.
1045
1046Sometimes this capability is rather handy when you want to work in one
1047locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1048example, I use this script to start C<xjdic>, which first switches to a
1049locale supported by xjdic and back later:
1050
1051 printf '\e]701;%s\007' ja_JP.SJIS
1052 xjdic -js
1053 printf '\e]701;%s\007' de_DE.UTF-8
1054
1055=item Can I switch the fonts at runtime?
1056
1057Yes, using an escape sequence. Try sth. like this, which has the same
1058effect as using the C<-fn> switch, and takes effect immediately:
1059
1060 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1061
1062This is useful if you e.g. work primarily with japanese (and prefer a
1063japanese font), but you have to switch to chinese temporarily, where
1064japanese fonts would only be in your way.
1065
1066You can think of this as a kind of manual ISO-2022 switching.

1068=item Mouse cut/paste suddenly no longer works.
1069
1070Make sure that mouse reporting is actually turned off since killing
1071some editors prematurely may leave the mouse in mouse report mode. I've
1072heard that tcsh may use mouse reporting unless it otherwise specified. A
1073quick check is to see if cut/paste works when the Alt or Shift keys are
1074depressed. See @@RXVT_NAME@@(7)
1075
1076=item What's with this bold/blink stuff?
1077
1078If no bold colour is set via C<colorBD:>, bold will invert text using the
1079standard foreground colour.
1080
1081For the standard background colour, blinking will actually make the
1082text blink when compiled with C<--enable-blinking>. with standard
1083colours. Without C<--enable-blinking>, the blink attribute will be
1084ignored.
1085
1086On ANSI colours, bold/blink attributes are used to set high-intensity
1087foreground/background colors.
1088
1089color0-7 are the low-intensity colors.
1090
1091color8-15 are the corresponding high-intensity colors.
1092
1093=item I don't like the screen colors. How do I change them?
1094
1095You can change the screen colors at run-time using F<~/.Xdefaults>
1096resources (or as long-options).
1097
1098Here are values that are supposed to resemble a VGA screen,
1099including the murky brown that passes for low-intensity yellow:
1100
1101 Rxvt*color0: #000000
1102 Rxvt*color1: #A80000
1103 Rxvt*color2: #00A800
1104 Rxvt*color3: #A8A800
1105 Rxvt*color4: #0000A8
1106 Rxvt*color5: #A800A8
1107 Rxvt*color6: #00A8A8
1108 Rxvt*color7: #A8A8A8
1109
1110 Rxvt*color8: #000054
1111 Rxvt*color9: #FF0054
1112 Rxvt*color10: #00FF54
1113 Rxvt*color11: #FFFF54
1114 Rxvt*color12: #0000FF
1115 Rxvt*color13: #FF00FF
1116 Rxvt*color14: #00FFFF
1117 Rxvt*color15: #FFFFFF
1118
1119=item What's with the strange Backspace/Delete key behaviour?
1120
1121Assuming that the physical Backspace key corresponds to the
1122BackSpace keysym (not likely for Linux ... see the following
1123question) there are two standard values that can be used for
1124Backspace: C<^H> and C<^?>.
1125
1126Historically, either value is correct, but rxvt-unicode adopts the debian
1127policy of using C<^?> when unsure, because it's the one only only correct
1128choice :).
1129
1130Rxvt-unicode tries to inherit the current stty settings and uses the value
1131of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1132started from a terminal (say, from a menu or by remote shell), then the
1133system value of `erase', which corresponds to CERASE in <termios.h>, will
1134be used (which may not be the same as your stty setting).
1135
1136For starting a new rxvt-unicode:
1137
1138 # use Backspace = ^H
1139 $ stty erase ^H
1140 $ @@RXVT_NAME@@ 1598@@RXVT_NAME@@.
1141
1142 # use Backspace = ^?
1143 $ stty erase ^?
1144 $ @@RXVT_NAME@@
1145
1146Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1147
1148For an existing rxvt-unicode:
1149
1150 # use Backspace = ^H
1151 $ stty erase ^H
1152 $ echo -n "^[[36h"
1153
1154 # use Backspace = ^?
1155 $ stty erase ^?
1156 $ echo -n "^[[36l"
1157
1158This helps satisfy some of the Backspace discrepancies that occur, but
1159if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1160properly reflects that.
1161
1162The Delete key is a another casualty of the ill-defined Backspace problem.
1163To avoid confusion between the Backspace and Delete keys, the Delete
1164key has been assigned an escape sequence to match the vt100 for Execute
1165(ESC[3~) and is in the supplied termcap/terminfo.
1166
1167Some other Backspace problems:
1168
1169some editors use termcap/terminfo,
1170some editors (vim I'm told) expect Backspace = ^H,
1171GNU Emacs (and Emacs-like editors) use ^H for help.
1172
1173Perhaps someday this will all be resolved in a consistent manner.
1174
1175=item I don't like the key-bindings. How do I change them?
1176
1177There are some compile-time selections available via configure. Unless
1178you have run "configure" with the C<--disable-resources> option you can
1179use the `keysym' resource to alter the keystrings associated with keysym
11800xFF00 - 0xFFFF (function, cursor keys, etc).
1181
1182Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'
1183
1184 !# ----- special uses ------:
1185 ! tn3270 login, remap function and arrow keys.

1222
1223=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1224How do I make use of them? For example, the Sun Keyboard type 4
1225has the following mappings that rxvt-unicode doesn't recognize.
1226
1227 KP_Insert == Insert
1228 F22 == Print
1229 F27 == Home
1230 F29 == Prior
1231 F33 == End
1232 F35 == Next
1233
1234Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1235mappings, it is better to use `xmodmap' to remap the keys as required for
1236your particular machine.
1237
1238=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1239I need this to decide about setting colors etc.
1240
1241rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1242check and see if that is set. Note that several programs, JED, slrn,
1243Midnight Commander automatically check this variable to decide whether or
1244not to use color.
1245
1246=item How do I set the correct, full IP address for the DISPLAY variable?
1247
1248If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1249insecure mode then it is possible to use the following shell script
1250snippets to correctly set the display. If your version of rxvt-unicode
1251wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1252the COLORTERM variable can be used to distinguish rxvt-unicode from a
1253regular xterm.
1254
