500Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
501which enables applications to easily embed a terminal.
502
503Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
504shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
505quite a bit, so don't expect it to keep some specific state. It's best to
506create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
507
508The window will not be destroyed when @@RXVT_NAME@@ exits.
509
510It might be useful to know that @@RXVT_NAME@@ will not close file
511descriptors passed to it (except for stdin/out/err, of course), so you
512can use file descriptors to communicate with the programs within the
513terminal. This works regardless of whether the C<-embed> option was used or
514not.
515
516Here is a short Gtk2-perl snippet that illustrates how this option can be
517used (a longer example is in F<doc/embed>):
518
519 my $rxvt = new Gtk2::Socket;
520 $rxvt->signal_connect_after (realize => sub {
521 my $xid = $_[0]->window->get_xid;
522 system "@@RXVT_NAME@@ -embed $xid &";
523 });

526
527Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
528pair but instead use the given file descriptor as the tty master. This is
529useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
530without having to run a program within it.
531
532If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
533entries and will not tinker with pty/tty permissions - you have to do that
534yourself if you want that.
535
536As an extremely special case, specifying C<-1> will completely suppress
537pty/tty operations, which is probably only useful in conjunction with some
538perl extension that manages the terminal.
539
540Here is a example in perl that illustrates how this option can be used (a
541longer example is in F<doc/pty-fd>):
542
543 use IO::Pty;
544 use Fcntl;
545
546 my $pty = new IO::Pty;

807omitted. This resource is only available when compiled with 1148
808KEYSYM_RESOURCE. 1149The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1150any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1151B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1152and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1153B<2>, B<3>, B<4>, B<5>.
1154
1155The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1156whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1157keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1158current application keymap mode state.
1159
1160The spellings of I<key> can be obtained by using B<xev>(1) command or
1161searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1162omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1163keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1164performed in an exact manner; however, the closest match is assured.
1165
1166I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1167number), see RESOURCES in C<man 7 X> for further details.
1168
1169You can define a range of keysyms in one shot by providing a I<string>
1170with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1171should be a character not used by the strings.
1172
1173Its usage can be demonstrated by an example:
1174
1175 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1176
1177The above line is equivalent to the following three lines:
1178
1179 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1180 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1181 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1182
1183If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1184is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1185example the following means "change the current locale to C<zh_CN.GBK>
1186when Control-Meta-c is being pressed":
1187
1188 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1189
1190If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1191is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1192manpage. For example, the F<selection> extension (activated via
1193C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1194
1195 URxvt.keysym.M-C-c: perl:selection:rot13
1196
1197Due the the large number of modifier combinations, a defined key mapping
1198will match if I<at least> the specified identifiers are being set, and
1199no other key mappings with those and more bits are being defined. That
1200means that defining a key map for C<a> will automatically provide
1201definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1202mappings themselves.
1203
1204Unfortunately, this will override built-in key mappings. For example
1205if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1206C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1207user-defined keymap using the C<builtin:> replacement:
1208
1209 URxvt.keysym.Insert: <my insert key sequence>
1210 URxvt.keysym.S-Insert: builtin:
1211
1212The first line defines a mapping for C<Insert> and I<any> combination
1213of modifiers. The second line re-establishes the default mapping for
1214C<Shift-Insert>.
1215
1216The following example will map Control-Meta-1 and Control-Meta-2 to
1217the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1218font-switching at runtime:
1219
1220 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1221 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1222
1223Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1224info):
1225
1226 URxvt.keysym.M-C-3: command:\033[8;25;80t

1233Comma-separated list(s) of perl extension scripts (default: C<default>) to
1234use in this terminal instance; option B<-pe>.
1235
1236Extension names can be prefixed with a C<-> sign to prohibit using
1237them. This can be useful to selectively disable some extensions loaded
1238by default, or specified via the C<perl-ext-common> resource. For
1239example, C<default,-selection> will use all the default extension except
1240C<selection>.
1241
1242Extension names can also be followed by an argument in angle brackets
1243(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1244searchable scrollback to Alt/Meta-s). Mentioning the same extension
1245multiple times with different arguments will pass multiple arguments to
1246the extension.
1247
1248Each extension is looked up in the library directories, loaded if
1249necessary, and bound to the current terminal instance.
1250
1251If both of these resources are the empty string, then the perl
1252interpreter will not be initialized. The idea behind two options is that
1253B<perl-ext-common> will be used for extensions that should be available to

1496
1497 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1498 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1501steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

1521=head2 ALPHA CHANNEL SUPPORT
1522
1523If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1524their act together, rxvt-unicode will do it's own alpha channel management:
1525
1526You can prefix any colour with an opaqueness percentage enclosed in
1527brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1528(0-100) that specifies the opacity of the colour, where C<0> is completely
1529transparent and C<100> is completely opaque. For example, C<[50]red> is a
1530half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1531is the recommended format to specify transparency values, and works with
1532all ways to specify a colour.
1533
1534For complete control, rxvt-unicode also supports
1535C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1536specifications, where the additional C<aaaa> component specifies opacity
1537(alpha) values. The minimum value of C<0000> is completely transparent,
1538while C<ffff> is completely opaque). The two example colours from
1539earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1540C<rgba:0000/ff00/0000/f332>.
1541
1542You probably need to specify B<"-depth 32">, too, to force a visual with
1543alpha channels, and have the luck that your X-server uses ARGB pixel
1544layout, as X is far from just supporting ARGB visuals out of the box, and
1545rxvt-unicode just fudges around.
1546
1547For example, the following selects an almost completely transparent black
1548background, and an almost opaque pink foreground:
1549
1550 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1551
1552When not using a background image, then the interpretation of the
1553alpha channel is up to your compositing manager (most interpret it as
1554transparency of course).
1555
1556When using a background pixmap or pseudo-transparency, then the background
1557colour will always behave as if it were completely transparent (so the
1558background image shows instead), regardless of how it was specified, while
1559other colours will either be transparent as specified (the background
1560image will show through) on servers supporting the RENDER extension, or
1561fully opaque on servers not supporting the RENDER EXTENSION.
1562
1563Please note that due to bugs in Xft, specifying alpha values might result
1564in garbage being displayed when the X-server does not support the RENDER
1565extension.
