487
488Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
489which enables applications to easily embed a terminal.
490
491Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
492shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
493quite a bit, so don't expect it to keep some specific state. It's best to
494create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
495
496The window will not be destroyed when @@RXVT_NAME@@ exits.
497
498It might be useful to know that @@RXVT_NAME@@ will not close file
499descriptors passed to it (except for stdin/out/err, of course), so you
500can use file descriptors to communicate with the programs within the
501terminal. This works regardless of whether the C<-embed> option was used or
502not.
503
504Here is a short Gtk2-perl snippet that illustrates how this option can be
505used (a longer example is in F<doc/embed>):
506
507 my $rxvt = new Gtk2::Socket;
508 $rxvt->signal_connect_after (realize => sub {
509 my $xid = $_[0]->window->get_xid;
510 system "@@RXVT_NAME@@ -embed $xid &";
511 });
512
513=item B<-pty-fd> I<file descriptor>
514
515Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
516pair but instead use the given file descriptor as the tty master. This is
517useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
518without having to run a program within it.
519
520If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
521entries and will not tinker with pty/tty permissions - you have to do that
522yourself if you want that.
523
524As an extremely special case, specifying C<-1> will completely suppress
525pty/tty operations, which is probably only useful in conjunction with some
526perl extension that manages the terminal.
527
528Here is a example in perl that illustrates how this option can be used (a
529longer example is in F<doc/pty-fd>):
530
531 use IO::Pty;
532 use Fcntl;
533
534 my $pty = new IO::Pty;
535 fcntl $pty, F_SETFD, 0; # clear close-on-exec
536 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
537 close $pty;
538
539 # now communicate with rxvt
540 my $slave = $pty->slave;
541 while (<$slave>) { print $slave "got <$_>\n" }
542
543Note that, despite what the name might imply, the file descriptor does not
544need to be a pty, it can be a bi-directional pipe as well (e.g. a unix
545domain or tcp socket). While tty operations cannot be done in this case,
546B<@@RXVT_NAME@@> can still be remote controlled with it:
547
548 use Socket;
549 use Fcntl;
550
551 socketpair my $URXVT, my $slave, Socket::AF_UNIX, Socket::SOCK_STREAM, Socket::PF_UNSPEC;
552 fcntl $slave, Fcntl::F_SETFD, 0;
553 system "exec @@RXVT_NAME@@ -pty-fd " . (fileno $slave) . " &";
554 close $slave;
555
556 syswrite $URXVT, "Type a secret password: ";
557 my $secret = do { local $/ = "\r"; <$URXVT> };
558 print "Not so secret anymore: $secret\n";

807omitted. This resource is only available when compiled with 1137terminal scroll up or down the way you want it, or any other thing an
808KEYSYM_RESOURCE. 1138extension might provide.
1139
1140The key combination that triggers the action, I<sym>, has the following format:
1141
1142 (modifiers-)key
1143
1144Where I<modifiers> can be any combination of the following full or
1145abbreviated modifier names:
1146
1147=begin table
1148
1149 B<ISOLevel3> B<I>
1150 B<AppKeypad> B<K>
1151 B<Control> B<C>
1152 B<NumLock> B<N>
1153 B<Shift> B<S>

1155 B<Lock> B<L>
1156 B<Mod1> B<1>
1157 B<Mod2> B<2>
1158 B<Mod3> B<3>
1159 B<Mod4> B<4>
1160 B<Mod5> B<5>
1161
1162=end table
1163
1164The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1165whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1166keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1167current application keymap mode state.
1168
1169Due the the large number of modifier combinations, a key mapping will
1170match if I<at least> the specified identifiers are being set, and no other
1171key mappings with those and more bits are being defined. That means that
1172defining a mapping for C<a> will automatically provide definitions for
1173C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1174themselves. See the C<builtin:> action, below, for a way to work around
1175this when this is a problem.
1176
1177The spelling of I<key> depends on your implementation of X. An easy way to
1178find a key name is to use the B<xev>(1) command. You can find a list by
1179looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1180the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1181value (B<0x0000 - 0xFFFF>).
1182
1183As with any resource value, the I<action> string may contain backslash
1184escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1185number), see RESOURCES in C<man 7 X> for further details.
1186
1187An action starts with an action prefix that selects a certain type
1188of action, followed by a colon. An action string without colons is
1189interpreted as a literal string to pass to the tty (as if it was
1190prefixed with C<string:>).
1191
1192The following action prefixes are known - extensions can provide
1193additional prefixes:
1194
1195=over
1196
1197=item string:STRING
1198
1199If the I<action> starts with C<string:> (or otherwise contains no colons),
1200then the remaining C<STRING> will be passed to the program running in the
1201terminal. For example, you could replace whatever Shift-Tab outputs by the
1202string C<echo rm -rf /> followed by a newline:
1203
1204 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1205
1206This could in theory be used to completely redefine your keymap.
1207
1208In addition, for actions of this type, you can define a range of
1209keysyms in one shot by loading the C<keysym-list> perl extension and
1210providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
1211the delimiter `/' should be a character not used by the strings.
1212
1213Its usage can be demonstrated by an example:
1214
1215 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1216
1217The above line is equivalent to the following three lines:
1218
1219 URxvt.keysym.Meta-Control-0x61: string:\033<a>
1220 URxvt.keysym.Meta-Control-0x62: string:\033<b>
1221 URxvt.keysym.Meta-Control-0x63: string:\033<c>
1222
1223=item command:STRING
1224
1225If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1226is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1227the opposite of C<string:> - instead of sending it to the program running
1228in the terminal, it will be treated as if it were program output). This is
1229most useful to feed command sequences into @@RXVT_NAME@@.
1230
1231For example the following means "change the current locale to C<zh_CN.GBK>
1232when Control-Meta-c is being pressed":
1233
1234 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1235
1236The following example will map Control-Meta-1 and Control-Meta-2 to
1237the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1238font-switching at runtime:
1239
1240 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1241 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1242
1243Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1244info):
1245
1246 URxvt.keysym.M-C-3: command:\033[8;25;80t
1247 URxvt.keysym.M-C-4: command:\033[8;48;110t
1248
1249=item builtin:
1250
1251The builtin action is the action that @@RXVT_NAME@@ would execute if no
1252key binding existed for the key combination. The obvious use is to undo
1253the effect of existing bindings. The not so obvious use is to reinstate
1254bindings when another binding overrides too many modifiers.
1255
1256For example if you overwrite the C<Insert> key you will disable
1257@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1258"holes" into the user-defined keymap using the C<builtin:> replacement:
1259
1260 URxvt.keysym.Insert: <my insert key sequence>
1261 URxvt.keysym.S-Insert: builtin:
1262
1263The first line defines a mapping for C<Insert> and I<any> combination
1264of modifiers. The second line re-establishes the default mapping for
1265C<Shift-Insert>.
1266
1267=item builtin-string:
1268
1269This action is mainly useful to restore string mappings for keys that
1270have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1271difficult to explain - basically, this action will send the string to the
1272application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1273action for it.
1274
1275An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1276selection when you press C<Shift-Insert>. With the following bindings, it
1277would instead emit the (undocumented, but what applications running in the
1278terminal might expect) sequence C<ESC [ 2 $> instead:
1279
1280 URxvt.keysym.S-Insert: builtin-string:
1281 URxvt.keysym.C-S-Insert: builtin:
1282
1283The first line disables the paste functionality for that key
1284combination, and the second reinstates the default behaviour for
1285C<Control-Shift-Insert>, which would otherwise be overridden.
1286
1287Similarly, to let applications gain access to the C<C-M-c> (copy to
1288clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1289this:
1290
1291 URxvt.keysym.C-M-c: builtin-string:
1292 URxvt.keysym.C-M-v: builtin-string:
1293
1294=item EXTENSION:STRING
1295
1296An action of this form invokes the action B<STRING>, if any, provided
1297by the @@RXVT_NAME@@perl(3) extension B<EXTENSION>. The extension will
1298be loaded automatically if necessary.
1299
1300Not all extensions define actions, but popular extensions that do
1301include the I<selection> and I<matcher> extensions (documented in their
1302own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
1303respectively).

1322Comma-separated list(s) of perl extension scripts (default: C<default>) to
1323use in this terminal instance; option B<-pe>.
1324
1325Extension names can be prefixed with a C<-> sign to remove them again, in
1326case they had been specified earlier. This can be useful to selectively
1327disable some extensions loaded by default, or specified via the
1328C<perl-ext-common> resource. For example, C<default,-selection> will use
1329all the default extensions except C<selection>.
1330
1331To prohibit autoloading of extensions, you can prefix them with C</>,
1332which will make urxvt refuse to automatically load them (this can be
1333overridden, however, by specifying the extension name again without a
1334prefix, though). This does not prohibit extensions themselves loading
1335other extensions. For example, C<default,/background> will keep the
1336C<background> extension from being loaded when a background OSC sequence
1337is received.
1338
1339The default set includes the C<selection>, C<option-popup>,
1340C<selection-popup>, C<readline>, C<searchable-scrollback> and
1341C<confirm-paste> extensions, as well as any extensions which are mentioned
1342in B<keysym> resources.
1343
1344Any extension such that a corresponding resource is given on the
1345command line is automatically appended to B<perl-ext>.
1346
1347Each extension is looked up in the library directories, loaded if
1348necessary, and bound to the current terminal instance. When the library
1349search path contains multiple extension files of the same name, then the
1350first one found will be used.
1351
1352If both of these resources are the empty string, then the perl interpreter
1353will not be initialized. The rationale for having two options is that
1354B<perl-ext-common> will be used for extensions that should be available to
1355all instances, while B<perl-ext> is used for specific instances.

1639=head2 ALPHA CHANNEL SUPPORT
1640
1641If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1642their act together, rxvt-unicode will do its own alpha channel management:
1643
1644You can prefix any colour with an opaqueness percentage enclosed in
1645brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1646(0-100) that specifies the opacity of the colour, where C<0> is completely
1647transparent and C<100> is completely opaque. For example, C<[50]red> is a
1648half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1649is the recommended format to specify transparency values, and works with
1650all ways to specify a colour.
1651
1652For complete control, rxvt-unicode also supports
1653C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1654specifications, where the additional C<aaaa> component specifies opacity
1655(alpha) values. The minimum value of C<0000> is completely transparent,
1656while C<ffff> is completely opaque). The two example colours from
1657earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1658C<rgba:0000/ff00/0000/f332>.
1659
1660You probably need to specify B<"-depth 32">, too, to force a visual with
1661alpha channels, and have the luck that your X-server uses ARGB pixel
1662layout, as X is far from just supporting ARGB visuals out of the box, and
1663rxvt-unicode just fudges around.
1664
1665For example, the following selects an almost completely transparent black
1666background, and an almost opaque pink foreground:
1667
1668 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1669
1670When not using a background image, then the interpretation of the
1671alpha channel is up to your compositing manager (most interpret it as
1672transparency of course).
1673
1674When using a background pixmap or pseudo-transparency, then the background
1675colour will always behave as if it were completely transparent (so the
1676background image shows instead), regardless of how it was specified, while
1677other colours will either be transparent as specified (the background
1678image will show through) on servers supporting the RENDER extension, or
1679fully opaque on servers not supporting the RENDER EXTENSION.
1680
1681Please note that due to bugs in Xft, specifying alpha values might result
1682in garbage being displayed when the X-server does not support the RENDER
1683extension.
