481Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
482which enables applications to easily embed a terminal.
483
484Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
485shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
486quite a bit, so don't expect it to keep some specific state. It's best to
487create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
488
489The window will not be destroyed when @@RXVT_NAME@@ exits.
490
491It might be useful to know that @@RXVT_NAME@@ will not close file
492descriptors passed to it (except for stdin/out/err, of course), so you
493can use file descriptors to communicate with the programs within the
494terminal. This works regardless of whether the C<-embed> option was used or
495not.
496
497Here is a short Gtk2-perl snippet that illustrates how this option can be
498used (a longer example is in F<doc/embed>):
499
500 my $rxvt = new Gtk2::Socket;
501 $rxvt->signal_connect_after (realize => sub {
502 my $xid = $_[0]->window->get_xid;
503 system "@@RXVT_NAME@@ -embed $xid &";
504 });

507
508Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
509pair but instead use the given file descriptor as the tty master. This is
510useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
511without having to run a program within it.
512
513If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
514entries and will not tinker with pty/tty permissions - you have to do that
515yourself if you want that.
516
517As an extremely special case, specifying C<-1> will completely suppress
518pty/tty operations, which is probably only useful in conjunction with some
519perl extension that manages the terminal.
520
521Here is a example in perl that illustrates how this option can be used (a
522longer example is in F<doc/pty-fd>):
523
524 use IO::Pty;
525 use Fcntl;
526
527 my $pty = new IO::Pty;

828omitted. This resource is only available when compiled with 1177
829KEYSYM_RESOURCE. 1178The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1179any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1180B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1181and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1182B<2>, B<3>, B<4>, B<5>.
1183
1184The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1185whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1186keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1187current application keymap mode state.
1188
1189The spellings of I<key> can be obtained by using B<xev>(1) command or
1190searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1191omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1192keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1193performed in an exact manner; however, the closest match is assured.
1194
1195I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1196number), see RESOURCES in C<man 7 X> for further details.
1197
1198You can define a range of keysyms in one shot by
1199loading the C<keysym-list> perl extension and providing a I<string>
1200with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1201should be a character not used by the strings.
1202
1203Its usage can be demonstrated by an example:
1204
1205 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1206
1207The above line is equivalent to the following three lines:
1208
1209 URxvt.keysym.Meta-Control-0x61: \033<a>
1210 URxvt.keysym.Meta-Control-0x62: \033<b>
1211 URxvt.keysym.Meta-Control-0x63: \033<c>
1212
1213If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1214is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1215example the following means "change the current locale to C<zh_CN.GBK>
1216when Control-Meta-c is being pressed":
1217
1218 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1219
1220If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1221is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1222manpage. For example, the F<selection> extension (activated via
1223C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1224
1225 URxvt.keysym.M-C-c: perl:selection:rot13
1226
1227Due the the large number of modifier combinations, a defined key mapping
1228will match if I<at least> the specified identifiers are being set, and
1229no other key mappings with those and more bits are being defined. That
1230means that defining a key map for C<a> will automatically provide
1231definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1232mappings themselves.
1233
1234Unfortunately, this will override built-in key mappings. For example
1235if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1236C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1237user-defined keymap using the C<builtin:> replacement:
1238
1239 URxvt.keysym.Insert: <my insert key sequence>
1240 URxvt.keysym.S-Insert: builtin:
1241
1242The first line defines a mapping for C<Insert> and I<any> combination
1243of modifiers. The second line re-establishes the default mapping for
1244C<Shift-Insert>.
1245
1246The following example will map Control-Meta-1 and Control-Meta-2 to
1247the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1248font-switching at runtime:
1249
1250 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1251 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1252
1253Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1254info):
1255
1256 URxvt.keysym.M-C-3: command:\033[8;25;80t

1263Comma-separated list(s) of perl extension scripts (default: C<default>) to
1264use in this terminal instance; option B<-pe>.
1265
1266Extension names can be prefixed with a C<-> sign to prohibit using
1267them. This can be useful to selectively disable some extensions loaded
1268by default, or specified via the C<perl-ext-common> resource. For
1269example, C<default,-selection> will use all the default extension except
1270C<selection>.
1271
1272Extension names can also be followed by an argument in angle brackets
1273(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1274searchable scrollback to Alt/Meta-s). Mentioning the same extension
1275multiple times with different arguments will pass multiple arguments to
1276the extension.
1277
1278Each extension is looked up in the library directories, loaded if
1279necessary, and bound to the current terminal instance.
1280
1281If both of these resources are the empty string, then the perl
1282interpreter will not be initialized. The idea behind two options is that
1283B<perl-ext-common> will be used for extensions that should be available to

1528 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1551=head2 ALPHA CHANNEL SUPPORT
1552
1553If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1554their act together, rxvt-unicode will do its own alpha channel management:
1555
1556You can prefix any colour with an opaqueness percentage enclosed in
1557brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1558(0-100) that specifies the opacity of the colour, where C<0> is completely
1559transparent and C<100> is completely opaque. For example, C<[50]red> is a
1560half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1561is the recommended format to specify transparency values, and works with
1562all ways to specify a colour.
1563
1564For complete control, rxvt-unicode also supports
1565C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1566specifications, where the additional C<aaaa> component specifies opacity
1567(alpha) values. The minimum value of C<0000> is completely transparent,
1568while C<ffff> is completely opaque). The two example colours from
1569earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1570C<rgba:0000/ff00/0000/f332>.
1571
1572You probably need to specify B<"-depth 32">, too, to force a visual with
1573alpha channels, and have the luck that your X-server uses ARGB pixel
1574layout, as X is far from just supporting ARGB visuals out of the box, and
1575rxvt-unicode just fudges around.
1576
1577For example, the following selects an almost completely transparent black
1578background, and an almost opaque pink foreground:
1579
1580 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1581
1582When not using a background image, then the interpretation of the
1583alpha channel is up to your compositing manager (most interpret it as
1584transparency of course).
1585
1586When using a background pixmap or pseudo-transparency, then the background
1587colour will always behave as if it were completely transparent (so the
1588background image shows instead), regardless of how it was specified, while
1589other colours will either be transparent as specified (the background
1590image will show through) on servers supporting the RENDER extension, or
1591fully opaque on servers not supporting the RENDER EXTENSION.
1592
1593Please note that due to bugs in Xft, specifying alpha values might result
1594in garbage being displayed when the X-server does not support the RENDER
1595extension.
