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

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

828omitted. This resource is only available when compiled with 1189
829KEYSYM_RESOURCE. 1190The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1191any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1192B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1193and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1194B<2>, B<3>, B<4>, B<5>.
1195
1196The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1197whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1198keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1199current application keymap mode state.
1200
1201The spellings of I<key> can be obtained by using B<xev>(1) command or
1202searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1203omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1204keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1205performed in an exact manner; however, the closest match is assured.
1206
1207I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1208number), see RESOURCES in C<man 7 X> for further details.
1209
1210You can define a range of keysyms in one shot by
1211loading the C<keysym-list> perl extension and providing a I<string>
1212with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1213should be a character not used by the strings.
1214
1215Its usage can be demonstrated by an example:
1216
1217 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1218
1219The above line is equivalent to the following three lines:
1220
1221 URxvt.keysym.Meta-Control-0x61: \033<a>
1222 URxvt.keysym.Meta-Control-0x62: \033<b>
1223 URxvt.keysym.Meta-Control-0x63: \033<c>
1224
1225If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1226is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1227example the following means "change the current locale to C<zh_CN.GBK>
1228when Control-Meta-c is being pressed":
1229
1230 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1231
1232If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1233is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1234manpage. For example, the F<selection> extension (activated via
1235C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1236
1237 URxvt.keysym.M-C-c: perl:selection:rot13
1238
1239Due the the large number of modifier combinations, a defined key mapping
1240will match if I<at least> the specified identifiers are being set, and
1241no other key mappings with those and more bits are being defined. That
1242means that defining a key map for C<a> will automatically provide
1243definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1244mappings themselves.
1245
1246Unfortunately, this will override built-in key mappings. For example
1247if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1248C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1249user-defined keymap using the C<builtin:> replacement:
1250
1251 URxvt.keysym.Insert: <my insert key sequence>
1252 URxvt.keysym.S-Insert: builtin:
1253
1254The first line defines a mapping for C<Insert> and I<any> combination
1255of modifiers. The second line re-establishes the default mapping for
1256C<Shift-Insert>.
1257
1258The following example will map Control-Meta-1 and Control-Meta-2 to
1259the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1260font-switching at runtime:
1261
1262 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1263 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1264
1265Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1266info):
1267
1268 URxvt.keysym.M-C-3: command:\033[8;25;80t

1277
1278Extension names can be prefixed with a C<-> sign to prohibit using
1279them. This can be useful to selectively disable some extensions loaded
1280by default, or specified via the C<perl-ext-common> resource. For
1281example, C<default,-selection> will use all the default extension except
1282C<selection>.
1283
1284Extension names can also be followed by an argument in angle brackets
1285(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1286searchable scrollback to Alt/Meta-s). Mentioning the same extension
1287multiple times with different arguments will pass multiple arguments to
1288the extension.
1289
1290Each extension is looked up in the library directories, loaded if

1563=head2 ALPHA CHANNEL SUPPORT
1564
1565If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1566their act together, rxvt-unicode will do its own alpha channel management:
1567
1568You can prefix any colour with an opaqueness percentage enclosed in
1569brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1570(0-100) that specifies the opacity of the colour, where C<0> is completely
1571transparent and C<100> is completely opaque. For example, C<[50]red> is a
1572half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1573is the recommended format to specify transparency values, and works with
1574all ways to specify a colour.
1575
1576For complete control, rxvt-unicode also supports
1577C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1578specifications, where the additional C<aaaa> component specifies opacity
1579(alpha) values. The minimum value of C<0000> is completely transparent,
1580while C<ffff> is completely opaque). The two example colours from
1581earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1582C<rgba:0000/ff00/0000/f332>.
1583
1584You probably need to specify B<"-depth 32">, too, to force a visual with
1585alpha channels, and have the luck that your X-server uses ARGB pixel
1586layout, as X is far from just supporting ARGB visuals out of the box, and
1587rxvt-unicode just fudges around.
1588
1589For example, the following selects an almost completely transparent black
1590background, and an almost opaque pink foreground:
1591
1592 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1593
1594When not using a background image, then the interpretation of the
1595alpha channel is up to your compositing manager (most interpret it as
1596transparency of course).
1597
1598When using a background pixmap or pseudo-transparency, then the background
1599colour will always behave as if it were completely transparent (so the
1600background image shows instead), regardless of how it was specified, while
1601other colours will either be transparent as specified (the background
1602image will show through) on servers supporting the RENDER extension, or
1603fully opaque on servers not supporting the RENDER EXTENSION.
1604
1605Please note that due to bugs in Xft, specifying alpha values might result
1606in garbage being displayed when the X-server does not support the RENDER
1607extension.
