464
465Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
466which enables applications to easily embed a terminal.
467
468Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
469shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
470quite a bit, so don't expect it to keep some specific state. It's best to
471create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
472
473The window will not be destroyed when @@RXVT_NAME@@ exits.
474
475It might be useful to know that @@RXVT_NAME@@ will not close file
476descriptors passed to it (except for stdin/out/err, of course), so you
477can use file descriptors to communicate with the programs within the
478terminal. This works regardless of whether the C<-embed> option was used or
479not.
480
481Here is a short Gtk2-perl snippet that illustrates how this option can be
482used (a longer example is in F<doc/embed>):
483
484 my $rxvt = new Gtk2::Socket;
485 $rxvt->signal_connect_after (realize => sub {
486 my $xid = $_[0]->window->get_xid;
487 system "@@RXVT_NAME@@ -embed $xid &";
488 });

491
492Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
493pair but instead use the given file descriptor as the tty master. This is
494useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
495without having to run a program within it.
496
497If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
498entries and will not tinker with pty/tty permissions - you have to do that
499yourself if you want that.
500
501As an extremely special case, specifying C<-1> will completely suppress
502pty/tty operations, which is probably only useful in conjunction with some
503perl extension that manages the terminal.
504
505Here is a example in perl that illustrates how this option can be used (a
506longer example is in F<doc/pty-fd>):
507
508 use IO::Pty;
509 use Fcntl;
510
511 my $pty = new IO::Pty;

828omitted. This resource is only available when compiled with 1077terminal scroll up or down the way you want it, or any other thing an
829KEYSYM_RESOURCE. 1078extension might provide.
1079
1080The key combination that triggers the action, I<sym>, has the following format:
1081
1082 (modifiers-)key
1083
1084Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
1085B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
1086B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
1087B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
1088
1089The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1090whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1091keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1092current application keymap mode state.
1093
1094Due the the large number of modifier combinations, a key mapping will
1095match if I<at least> the specified identifiers are being set, and no other
1096key mappings with those and more bits are being defined. That means that
1097defining a mapping for C<a> will automatically provide definitions for
1098C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1099themselves. See the C<builtin:> action, below, for a way to work around
1100this when this is a problem.
1101
1102The spelling of I<key> depends on your implementation of X. An easy way to
1103find a key name is to use the B<xev>(1) command. You can find a list by
1104looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1105the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1106value (B<0x0000 - 0xFFFF>).
1107
1108As with any resource value, the I<action> string may contain backslash
1109escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1110number), see RESOURCES in C<man 7 X> for further details.
1111
1112An action starts with an action prefix that selects a certain type
1113of action, followed by a colon. An action string without colons is
1114interpreted as a literal string to pass to the tty (as if it was
1115prefixed with C<string:>).
1116
1117The following action prefixes are known - extensions can provide
1118additional prefixes:
1119
1120=over 4
1121
1122=item string:STRING
1123
1124If the I<action> starts with C<string:> (or otherwise contains no colons),
1125then the remaining C<STRING> will be passed to the program running in the
1126terminal. For example, you could replace whatever Shift-Tab outputs by the
1127string C<echo rm -rf /> followed by a newline:
1128
1129 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1130
1131This could in theory be used to completely redefine your keymap.
1132
1133In addition, for actions of this type, you can define a range of
1134keysyms in one shot by loading the C<keysym-list> perl extension and
1135providing an I<action> with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where
1136the delimiter `/' should be a character not used by the strings.
1137
1138Its usage can be demonstrated by an example:
1139
1140 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1141
1142The above line is equivalent to the following three lines:
1143
1144 URxvt.keysym.Meta-Control-0x61: string:\033<a>
1145 URxvt.keysym.Meta-Control-0x62: string:\033<b>
1146 URxvt.keysym.Meta-Control-0x63: string:\033<c>
1147
1148=item command:STRING
1149
1150If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1151is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1152the opposite of C<string:> - instead of sending it to the program running
1153in the terminal, it will be treated as if it were program output). This is
1154most useful to feed command sequences into @@RXVT_NAME@@.
1155
1156For example the following means "change the current locale to C<zh_CN.GBK>
1157when Control-Meta-c is being pressed":
1158
1159 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1160
1161The following example will map Control-Meta-1 and Control-Meta-2 to
1162the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1163font-switching at runtime:
1164
1165 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1166 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1167
1168Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1169info):
1170
1171 URxvt.keysym.M-C-3: command:\033[8;25;80t
1172 URxvt.keysym.M-C-4: command:\033[8;48;110t
1173
1174=item builtin:
1175
1176The builtin action is the action that @@RXVT_NAME@@ would execute if no
1177key binding existed for the key combination. The obvious use is to undo
1178the effect of existing bindings. The not so obvious use is to reinstate
1179bindings when another binding overrides too many modifiers.
1180
1181For example if you overwrite the C<Insert> key you will disable
1182@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1183"holes" into the user-defined keymap using the C<builtin:> replacement:
1184
1185 URxvt.keysym.Insert: <my insert key sequence>
1186 URxvt.keysym.S-Insert: builtin:
1187
1188The first line defines a mapping for C<Insert> and I<any> combination
1189of modifiers. The second line re-establishes the default mapping for
1190C<Shift-Insert>.
1191
1192=item builtin-string:
1193
1194This action is mainly useful to restore string mappings for keys that
1195have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1196difficult to explain - basically, this action will send the string to the
1197application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1198action for it.
1199
1200An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1201selection when you press C<Shift-Insert>. With the following bindings, it
1202would instead emit the (undocumented, but what applications running in the
1203terminal might expect) sequence C<ESC [ 2 $> instead:
1204
1205 URxvt.keysym.S-Insert: builtin-string:
1206 URxvt.keysym.C-S-Insert: builtin:
1207
1208The first line disables the paste functionality for that key
1209combination, and the second reinstates the default behaviour for
1210C<Control-Shift-Insert>, which would otherwise be overridden.
1211
1212Similarly, to let applications gain access to the C<C-M-c> (copy to
1213clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1214this:

1247Comma-separated list(s) of perl extension scripts (default: C<default>) to
1248use in this terminal instance; option B<-pe>.
1249
1250Extension names can be prefixed with a C<-> sign to prohibit using
1251them. This can be useful to selectively disable some extensions loaded
1252by default, or specified via the C<perl-ext-common> resource. For
1253example, C<default,-selection> will use all the default extensions except
1254C<selection>.
1255
1256The default set includes the C<selection>, C<option-popup>,
1257C<selection-popup>, C<readline> and C<searchable-scrollback>
1258extensions, and extensions which are mentioned in B<keysym> resources.
1259
1260Any extension such that a corresponding resource is given on the
1261command line is automatically appended to B<perl-ext>.
1262
1263Each extension is looked up in the library directories, loaded if
1264necessary, and bound to the current terminal instance. When the library
1265search path contains multiple extension files of the same name, then the
1266first one found will be used.
1267
1268If both of these resources are the empty string, then the perl interpreter
1269will not be initialized. The rationale for having two options is that
1270B<perl-ext-common> will be used for extensions that should be available to
1271all instances, while B<perl-ext> is used for specific instances.

1667(0-100) that specifies the opacity of the colour, where C<0> is completely
1668transparent and C<100> is completely opaque. For example, C<[50]red> is a
1669half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1670is the recommended format to specify transparency values, and works with
1671all ways to specify a colour.
1672
1673For complete control, rxvt-unicode also supports
1674C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1675specifications, where the additional C<aaaa> component specifies opacity
1676(alpha) values. The minimum value of C<0000> is completely transparent,
1677while C<ffff> is completely opaque). The two example colours from
1678earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1679C<rgba:0000/ff00/0000/f332>.
1680
1681You probably need to specify B<"-depth 32">, too, to force a visual with
1682alpha channels, and have the luck that your X-server uses ARGB pixel
1683layout, as X is far from just supporting ARGB visuals out of the box, and
1684rxvt-unicode just fudges around.
1685
1686For example, the following selects an almost completely transparent black
1687background, and an almost opaque pink foreground:
1688
1689 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1690
1691When not using a background image, then the interpretation of the
1692alpha channel is up to your compositing manager (most interpret it as
1693transparency of course).
1694
1695When using a background pixmap or pseudo-transparency, then the background
1696colour will always behave as if it were completely transparent (so the
1697background image shows instead), regardless of how it was specified, while
1698other colours will either be transparent as specified (the background
1699image will show through) on servers supporting the RENDER extension, or
1700fully opaque on servers not supporting the RENDER EXTENSION.
1701
1702Please note that due to bugs in Xft, specifying alpha values might result
1703in garbage being displayed when the X-server does not support the RENDER
1704extension.
