502
503Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
504which enables applications to easily embed a terminal.
505
506Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
507shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
508quite a bit, so don't expect it to keep some specific state. It's best to
509create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
510
511The window will not be destroyed when @@RXVT_NAME@@ exits.
512
513It might be useful to know that @@RXVT_NAME@@ will not close file
514descriptors passed to it (except for stdin/out/err, of course), so you
515can use file descriptors to communicate with the programs within the
516terminal. This works regardless of whether the C<-embed> option was used or
517not.
518
519Here is a short Gtk2-perl snippet that illustrates how this option can be
520used (a longer example is in F<doc/embed>):
521
522 my $rxvt = new Gtk2::Socket;
523 $rxvt->signal_connect_after (realize => sub {
524 my $xid = $_[0]->window->get_xid;
525 system "@@RXVT_NAME@@ -embed $xid &";
526 });

529
530Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
531pair but instead use the given file descriptor as the tty master. This is
532useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
533without having to run a program within it.
534
535If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
536entries and will not tinker with pty/tty permissions - you have to do that
537yourself if you want that.
538
539As an extremely special case, specifying C<-1> will completely suppress
540pty/tty operations, which is probably only useful in conjunction with some
541perl extension that manages the terminal.
542
543Here is a example in perl that illustrates how this option can be used (a
544longer example is in F<doc/pty-fd>):
545
546 use IO::Pty;
547 use Fcntl;
548
549 my $pty = new IO::Pty;
550 fcntl $pty, F_SETFD, 0; # clear close-on-exec

828omitted. This resource is only available when compiled with 1153
829KEYSYM_RESOURCE. 1154The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1155any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1156B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1157and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1158B<2>, B<3>, B<4>, B<5>.
1159
1160The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1161whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1162keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1163current application keymap mode state.
1164
1165The spellings of I<key> can be obtained by using B<xev>(1) command or
1166searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1167omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1168keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1169performed in an exact manner; however, the closest match is assured.
1170
1171I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1172number), see RESOURCES in C<man 7 X> for further details.
1173
1174You can define a range of keysyms in one shot by providing a I<string>
1175with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1176should be a character not used by the strings.
1177
1178Its usage can be demonstrated by an example:
1179
1180 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1181
1182The above line is equivalent to the following three lines:
1183
1184 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1185 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1186 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1187
1188If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1189is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1190example the following means "change the current locale to C<zh_CN.GBK>
1191when Control-Meta-c is being pressed":
1192
1193 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1194
1195If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1196is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1197manpage. For example, the F<selection> extension (activated via
1198C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1199
1200 URxvt.keysym.M-C-c: perl:selection:rot13
1201
1202Due the the large number of modifier combinations, a defined key mapping
1203will match if at I<at least> the specified identifiers are being set, and
1204no other key mappings with those and more bits are being defined. That
1205means that defining a key map for C<a> will automatically provide
1206definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1207mappings themselves.
1208
1209Unfortunately, this will override built-in key mappings. For example
1210if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1211C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1212user-defined keymap using the C<builtin:> replacement:
1213
1214 URxvt.keysym.Insert: <my insert key sequence>
1215 URxvt.keysym.S-Insert: builtin:
1216
1217The first line defines a mapping for C<Insert> and I<any> combination
1218of modifiers. The second line re-establishes the default mapping for
1219C<Shift-Insert>.
1220
1221The following example will map Control-Meta-1 and Control-Meta-2 to
1222the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1223font-switching at runtime:
1224
1225 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1226 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1227
1228Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1229info):
1230
1231 URxvt.keysym.M-C-3: command:\033[8;25;80t

1238Comma-separated list(s) of perl extension scripts (default: C<default>) to
1239use in this terminal instance; option B<-pe>.
1240
1241Extension names can be prefixed with a C<-> sign to prohibit using
1242them. This can be useful to selectively disable some extensions loaded
1243by default, or specified via the C<perl-ext-common> resource. For
1244example, C<default,-selection> will use all the default extension except
1245C<selection>.
1246
1247Extension names can also be followed by an argument in angle brackets
1248(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1249searchable scrollback to Alt/Meta-s). Mentioning the same extension
1250multiple times with different arguments will pass multiple arguments to
1251the extension.
1252
1253Each extension is looked up in the library directories, loaded if
1254necessary, and bound to the current terminal instance.
1255
1256If both of these resources are the empty string, then the perl
1257interpreter will not be initialized. The idea behind two options is that
1258B<perl-ext-common> will be used for extensions that should be available to

1503 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1526=head2 ALPHA CHANNEL SUPPORT
1527
1528If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1529their act together, rxvt-unicode will do it's own alpha channel management:
1530
1531You can prefix any colour with an opaqueness percentage enclosed in
1532brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1533(0-100) that specifies the opacity of the colour, where C<0> is completely
1534transparent and C<100> is completely opaque. For example, C<[50]red> is a
1535half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1536is the recommended format to specify transparency values, and works with
1537all ways to specify a colour.
1538
1539For complete control, rxvt-unicode also supports
1540C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1541specifications, where the additional C<aaaa> component specifies opacity
1542(alpha) values. The minimum value of C<0000> is completely transparent,
1543while C<ffff> is completely opaque). The two example colours from
1544earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1545C<rgba:0000/ff00/0000/f332>.
1546
1547You probably need to specify B<"-depth 32">, too, to force a visual with
1548alpha channels, and have the luck that your X-server uses ARGB pixel
1549layout, as X is far from just supporting ARGB visuals out of the box, and
1550rxvt-unicode just fudges around.
1551
1552For example, the following selects an almost completely transparent black
1553background, and an almost opaque pink foreground:
1554
1555 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1556
1557When not using a background image, then the interpretation of the
1558alpha channel is up to your compositing manager (most interpret it as
1559transparency of course).
1560
1561When using a background pixmap or pseudo-transparency, then the background
1562colour will always behave as if it were completely transparent (so the
1563background image shows instead), regardless of how it was specified, while
1564other colours will either be transparent as specified (the background
1565image will show through) on servers supporting the RENDER extension, or
1566fully opaque on servers not supporting the RENDER EXTENSION.
1567
1568Please note that due to bugs in Xft, specifying alpha values might result
1569in garbage being displayed when the X-server does not support the RENDER
1570extension.
