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 1173
829KEYSYM_RESOURCE. 1174The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1175any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1176B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1177and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1178B<2>, B<3>, B<4>, B<5>.
1179
1180The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1181whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1182keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1183current application keymap mode state.
1184
1185The spellings of I<key> can be obtained by using B<xev>(1) command or
1186searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1187omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1188keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1189performed in an exact manner; however, the closest match is assured.
1190
1191I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1192number), see RESOURCES in C<man 7 X> for further details.
1193
1194You can define a range of keysyms in one shot by
1195loading the C<keysym-list> perl extension and providing a I<string>
1196with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1197should be a character not used by the strings.
1198
1199Its usage can be demonstrated by an example:
1200
1201 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1202
1203The above line is equivalent to the following three lines:
1204
1205 URxvt.keysym.Meta-Control-0x61: \033<a>
1206 URxvt.keysym.Meta-Control-0x62: \033<b>
1207 URxvt.keysym.Meta-Control-0x63: \033<c>
1208
1209If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1210is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1211example the following means "change the current locale to C<zh_CN.GBK>
1212when Control-Meta-c is being pressed":
1213
1214 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1215
1216If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1217is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1218manpage. For example, the F<selection> extension (activated via
1219C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1220
1221 URxvt.keysym.M-C-c: perl:selection:rot13
1222
1223Due the the large number of modifier combinations, a defined key mapping
1224will match if I<at least> the specified identifiers are being set, and
1225no other key mappings with those and more bits are being defined. That
1226means that defining a key map for C<a> will automatically provide
1227definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1228mappings themselves.
1229
1230Unfortunately, this will override built-in key mappings. For example
1231if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1232C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1233user-defined keymap using the C<builtin:> replacement:
1234
1235 URxvt.keysym.Insert: <my insert key sequence>
1236 URxvt.keysym.S-Insert: builtin:
1237
1238The first line defines a mapping for C<Insert> and I<any> combination
1239of modifiers. The second line re-establishes the default mapping for
1240C<Shift-Insert>.
1241
1242The following example will map Control-Meta-1 and Control-Meta-2 to
1243the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1244font-switching at runtime:
1245
1246 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1247 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1248
1249Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1250info):
1251
1252 URxvt.keysym.M-C-3: command:\033[8;25;80t

1259Comma-separated list(s) of perl extension scripts (default: C<default>) to
1260use in this terminal instance; option B<-pe>.
1261
1262Extension names can be prefixed with a C<-> sign to prohibit using
1263them. This can be useful to selectively disable some extensions loaded
1264by default, or specified via the C<perl-ext-common> resource. For
1265example, C<default,-selection> will use all the default extension except
1266C<selection>.
1267
1268Extension names can also be followed by an argument in angle brackets
1269(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1270searchable scrollback to Alt/Meta-s). Mentioning the same extension
1271multiple times with different arguments will pass multiple arguments to
1272the extension.
1273
1274Each extension is looked up in the library directories, loaded if
1275necessary, and bound to the current terminal instance.
1276
1277If both of these resources are the empty string, then the perl
1278interpreter will not be initialized. The idea behind two options is that
1279B<perl-ext-common> will be used for extensions that should be available to

1522
1523 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1524 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1527steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

1547=head2 ALPHA CHANNEL SUPPORT
1548
1549If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1550their act together, rxvt-unicode will do its own alpha channel management:
1551
1552You can prefix any colour with an opaqueness percentage enclosed in
1553brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1554(0-100) that specifies the opacity of the colour, where C<0> is completely
1555transparent and C<100> is completely opaque. For example, C<[50]red> is a
1556half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1557is the recommended format to specify transparency values, and works with
1558all ways to specify a colour.
1559
1560For complete control, rxvt-unicode also supports
1561C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1562specifications, where the additional C<aaaa> component specifies opacity
1563(alpha) values. The minimum value of C<0000> is completely transparent,
1564while C<ffff> is completely opaque). The two example colours from
1565earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1566C<rgba:0000/ff00/0000/f332>.
1567
1568You probably need to specify B<"-depth 32">, too, to force a visual with
1569alpha channels, and have the luck that your X-server uses ARGB pixel
1570layout, as X is far from just supporting ARGB visuals out of the box, and
1571rxvt-unicode just fudges around.
1572
1573For example, the following selects an almost completely transparent black
1574background, and an almost opaque pink foreground:
1575
1576 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1577
1578When not using a background image, then the interpretation of the
1579alpha channel is up to your compositing manager (most interpret it as
1580transparency of course).
1581
1582When using a background pixmap or pseudo-transparency, then the background
1583colour will always behave as if it were completely transparent (so the
1584background image shows instead), regardless of how it was specified, while
1585other colours will either be transparent as specified (the background
1586image will show through) on servers supporting the RENDER extension, or
1587fully opaque on servers not supporting the RENDER EXTENSION.
1588
1589Please note that due to bugs in Xft, specifying alpha values might result
1590in garbage being displayed when the X-server does not support the RENDER
1591extension.
