489
490Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
491which enables applications to easily embed a terminal.
492
493Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
494shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
495quite a bit, so don't expect it to keep some specific state. It's best to
496create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
497
498The window will not be destroyed when @@RXVT_NAME@@ exits.
499
500It might be useful to know that @@RXVT_NAME@@ will not close file
501descriptors passed to it (except for stdin/out/err, of course), so you
502can use file descriptors to communicate with the programs within the
503terminal. This works regardless of whether the C<-embed> option was used or
504not.
505
506Here is a short Gtk2-perl snippet that illustrates how this option can be
507used (a longer example is in F<doc/embed>):
508
509 my $rxvt = new Gtk2::Socket;
510 $rxvt->signal_connect_after (realize => sub {
511 my $xid = $_[0]->window->get_xid;
512 system "@@RXVT_NAME@@ -embed $xid &";

516
517Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
518pair but instead use the given file descriptor as the tty master. This is
519useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
520without having to run a program within it.
521
522If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
523entries and will not tinker with pty/tty permissions - you have to do that
524yourself if you want that.
525
526As an extremely special case, specifying C<-1> will completely suppress
527pty/tty operations, which is probably only useful in conjunction with some
528perl extension that manages the terminal.
529
530Here is a example in perl that illustrates how this option can be used (a
531longer example is in F<doc/pty-fd>):
532
533 use IO::Pty;
534 use Fcntl;
535
536 my $pty = new IO::Pty;
537 fcntl $pty, F_SETFD, 0; # clear close-on-exec

828omitted. This resource is only available when compiled with 1163
829KEYSYM_RESOURCE. 1164The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1165any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1166B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1167and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1168B<2>, B<3>, B<4>, B<5>.
1169
1170The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1171whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1172keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1173current application keymap mode state.
1174
1175The spellings of I<key> can be obtained by using B<xev>(1) command or
1176searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1177omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1178keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1179performed in an exact manner; however, the closest match is assured.
1180
1181I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1182number), see RESOURCES in C<man 7 X> for further details.
1183
1184You can define a range of keysyms in one shot by providing a I<string>
1185with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1186should be a character not used by the strings.
1187
1188Its usage can be demonstrated by an example:
1189
1190 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1191
1192The above line is equivalent to the following three lines:
1193
1194 URxvt.keysym.Meta-Control-0x61: \033<a>
1195 URxvt.keysym.Meta-Control-0x62: \033<b>
1196 URxvt.keysym.Meta-Control-0x63: \033<c>
1197
1198If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1199is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1200example the following means "change the current locale to C<zh_CN.GBK>
1201when Control-Meta-c is being pressed":
1202
1203 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1204
1205If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1206is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1207manpage. For example, the F<selection> extension (activated via
1208C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1209
1210 URxvt.keysym.M-C-c: perl:selection:rot13
1211
1212Due the the large number of modifier combinations, a defined key mapping
1213will match if I<at least> the specified identifiers are being set, and
1214no other key mappings with those and more bits are being defined. That
1215means that defining a key map for C<a> will automatically provide
1216definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1217mappings themselves.
1218
1219Unfortunately, this will override built-in key mappings. For example
1220if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1221C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1222user-defined keymap using the C<builtin:> replacement:
1223
1224 URxvt.keysym.Insert: <my insert key sequence>
1225 URxvt.keysym.S-Insert: builtin:
1226
1227The first line defines a mapping for C<Insert> and I<any> combination
1228of modifiers. The second line re-establishes the default mapping for
1229C<Shift-Insert>.
1230
1231The following example will map Control-Meta-1 and Control-Meta-2 to
1232the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1233font-switching at runtime:
1234
1235 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1236 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1237
1238Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1239info):
1240
1241 URxvt.keysym.M-C-3: command:\033[8;25;80t

1248Comma-separated list(s) of perl extension scripts (default: C<default>) to
1249use in this terminal instance; option B<-pe>.
1250
1251Extension names can be prefixed with a C<-> sign to prohibit using
1252them. This can be useful to selectively disable some extensions loaded
1253by default, or specified via the C<perl-ext-common> resource. For
1254example, C<default,-selection> will use all the default extension except
1255C<selection>.
1256
1257Extension names can also be followed by an argument in angle brackets
1258(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1259searchable scrollback to Alt/Meta-s). Mentioning the same extension
1260multiple times with different arguments will pass multiple arguments to
1261the extension.
1262
1263Each extension is looked up in the library directories, loaded if
1264necessary, and bound to the current terminal instance.
1265
1266If both of these resources are the empty string, then the perl
1267interpreter will not be initialized. The idea behind two options is that
1268B<perl-ext-common> will be used for extensions that should be available to
1269all instances, while B<perl-ext> is used for specific instances.

1513 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1536=head2 ALPHA CHANNEL SUPPORT
1537
1538If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1539their act together, rxvt-unicode will do it's own alpha channel management:
1540
1541You can prefix any colour with an opaqueness percentage enclosed in
1542brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1543(0-100) that specifies the opacity of the colour, where C<0> is completely
1544transparent and C<100> is completely opaque. For example, C<[50]red> is a
1545half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1546is the recommended format to specify transparency values, and works with
1547all ways to specify a colour.
1548
1549For complete control, rxvt-unicode also supports
1550C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1551specifications, where the additional C<aaaa> component specifies opacity
1552(alpha) values. The minimum value of C<0000> is completely transparent,
1553while C<ffff> is completely opaque). The two example colours from
1554earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1555C<rgba:0000/ff00/0000/f332>.
1556
1557You probably need to specify B<"-depth 32">, too, to force a visual with
1558alpha channels, and have the luck that your X-server uses ARGB pixel
1559layout, as X is far from just supporting ARGB visuals out of the box, and
1560rxvt-unicode just fudges around.
1561
1562For example, the following selects an almost completely transparent black
1563background, and an almost opaque pink foreground:
1564
1565 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1566
1567When not using a background image, then the interpretation of the
1568alpha channel is up to your compositing manager (most interpret it as
1569transparency of course).
1570
1571When using a background pixmap or pseudo-transparency, then the background
1572colour will always behave as if it were completely transparent (so the
1573background image shows instead), regardless of how it was specified, while
1574other colours will either be transparent as specified (the background
1575image will show through) on servers supporting the RENDER extension, or
1576fully opaque on servers not supporting the RENDER EXTENSION.
1577
1578Please note that due to bugs in Xft, specifying alpha values might result
1579in garbage being displayed when the X-server does not support the RENDER
1580extension.
