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 &";
513 });

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

807omitted. This resource is only available when compiled with 1141
808KEYSYM_RESOURCE. 1142The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1143any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1144B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1145and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1146B<2>, B<3>, B<4>, B<5>.
1147
1148The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1149whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1150keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1151current application keymap mode state.
1152
1153The spellings of I<key> can be obtained by using B<xev>(1) command or
1154searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1155omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1156keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1157performed in an exact manner; however, the closest match is assured.
1158
1159I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1160number), see RESOURCES in C<man 7 X> for further details.
1161
1162You can define a range of keysyms in one shot by providing a I<string>
1163with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1164should be a character not used by the strings.
1165
1166Its usage can be demonstrated by an example:
1167
1168 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1169
1170The above line is equivalent to the following three lines:
1171
1172 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1173 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1174 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1175
1176If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1177is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1178example the following means "change the current locale to C<zh_CN.GBK>
1179when Control-Meta-c is being pressed":
1180
1181 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1182
1183If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1184is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1185manpage. For example, the F<selection> extension (activated via
1186C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1187
1188 URxvt.keysym.M-C-c: perl:selection:rot13
1189
1190Due the the large number of modifier combinations, a defined key mapping
1191will match if I<at least> the specified identifiers are being set, and
1192no other key mappings with those and more bits are being defined. That
1193means that defining a key map for C<a> will automatically provide
1194definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1195mappings themselves.
1196
1197Unfortunately, this will override built-in key mappings. For example
1198if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1199C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1200user-defined keymap using the C<builtin:> replacement:
1201
1202 URxvt.keysym.Insert: <my insert key sequence>
1203 URxvt.keysym.S-Insert: builtin:
1204
1205The first line defines a mapping for C<Insert> and I<any> combination
1206of modifiers. The second line re-establishes the default mapping for
1207C<Shift-Insert>.
1208
1209The following example will map Control-Meta-1 and Control-Meta-2 to
1210the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1211font-switching at runtime:
1212
1213 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1214 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1215
1216Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1217info):
1218
1219 URxvt.keysym.M-C-3: command:\033[8;25;80t

1226Comma-separated list(s) of perl extension scripts (default: C<default>) to
1227use in this terminal instance; option B<-pe>.
1228
1229Extension names can be prefixed with a C<-> sign to prohibit using
1230them. This can be useful to selectively disable some extensions loaded
1231by default, or specified via the C<perl-ext-common> resource. For
1232example, C<default,-selection> will use all the default extension except
1233C<selection>.
1234
1235Extension names can also be followed by an argument in angle brackets
1236(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1237searchable scrollback to Alt/Meta-s). Mentioning the same extension
1238multiple times with different arguments will pass multiple arguments to
1239the extension.
1240
1241Each extension is looked up in the library directories, loaded if
1242necessary, and bound to the current terminal instance.
1243
1244If both of these resources are the empty string, then the perl
1245interpreter will not be initialized. The idea behind two options is that
1246B<perl-ext-common> will be used for extensions that should be available to

1489
1490 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1491 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1494steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

1514=head2 ALPHA CHANNEL SUPPORT
1515
1516If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1517their act together, rxvt-unicode will do it's own alpha channel management:
1518
1519You can prefix any colour with an opaqueness percentage enclosed in
1520brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1521(0-100) that specifies the opacity of the colour, where C<0> is completely
1522transparent and C<100> is completely opaque. For example, C<[50]red> is a
1523half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1524is the recommended format to specify transparency values, and works with
1525all ways to specify a colour.
1526
1527For complete control, rxvt-unicode also supports
1528C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1529specifications, where the additional C<aaaa> component specifies opacity
1530(alpha) values. The minimum value of C<0000> is completely transparent,
1531while C<ffff> is completely opaque). The two example colours from
1532earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1533C<rgba:0000/ff00/0000/f332>.
1534
1535You probably need to specify B<"-depth 32">, too, to force a visual with
1536alpha channels, and have the luck that your X-server uses ARGB pixel
1537layout, as X is far from just supporting ARGB visuals out of the box, and
1538rxvt-unicode just fudges around.
1539
1540For example, the following selects an almost completely transparent black
1541background, and an almost opaque pink foreground:
1542
1543 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1544
1545When not using a background image, then the interpretation of the
1546alpha channel is up to your compositing manager (most interpret it as
1547transparency of course).
1548
1549When using a background pixmap or pseudo-transparency, then the background
1550colour will always behave as if it were completely transparent (so the
1551background image shows instead), regardless of how it was specified, while
1552other colours will either be transparent as specified (the background
1553image will show through) on servers supporting the RENDER extension, or
1554fully opaque on servers not supporting the RENDER EXTENSION.
1555
1556Please note that due to bugs in Xft, specifying alpha values might result
1557in garbage being displayed when the X-server does not support the RENDER
1558extension.
