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 &";

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;

847can start or end with whitespace.
848 1165
849You can define a range of keysyms in one shot by providing a I<string>
850with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
851should be a character not used by the strings.
852
853Its usage can be demonstrated by an example:
854
855 URxvt.keysym.M-C-0x61: list|\e<M-C-|abc|>
856
857The above line is equivalent to the following three lines:
858
859 URxvt.keysym.Meta-Control-0x61: \e<M-C-a>
860 URxvt.keysym.Meta-Control-0x62: \e<M-C-b>
861 URxvt.keysym.Meta-Control-0x63: \e<M-C-c>

864interpreted and executed as @@RXVT_NAME@@'s control sequence. For example, 1167is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
865C<proto:\033]701;zh_CN.GBK\007> means: change the current locale to 1168example the following means "change the current locale to C<zh_CN.GBK>
866C<zh_CN.GBK>. 1169when Control-Meta-c is being pressed":
1170
1171 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1172
1173If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1174is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1175manpage. For example, the F<selection> extension (activated via
1176C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1177
1178 URxvt.keysym.M-C-c: perl:selection:rot13
1179
1180Due the the large number of modifier combinations, a defined key mapping
1181will match if I<at least> the specified identifiers are being set, and
1182no other key mappings with those and more bits are being defined. That
1183means that defining a key map for C<a> will automatically provide
1184definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1185mappings themselves.
1186
1187Unfortunately, this will override built-in key mappings. For example
1188if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1189C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1190user-defined keymap using the C<builtin:> replacement:
1191
1192 URxvt.keysym.Insert: <my insert key sequence>
1193 URxvt.keysym.S-Insert: builtin:
1194
1195The first line defines a mapping for C<Insert> and I<any> combination
1196of modifiers. The second line re-establishes the default mapping for
1197C<Shift-Insert>.
1198
1199The following example will map Control-Meta-1 and Control-Meta-2 to
1200the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1201font-switching at runtime:
1202
1203 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1204 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1205
1206Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1207info):
1208
1209 URxvt.keysym.M-C-3: command:\033[8;25;80t

1215
1216Comma-separated list(s) of perl extension scripts (default: C<default>) to
1217use in this terminal instance; option B<-pe>.
1218
1219Extension names can be prefixed with a C<-> sign to prohibit using
1220them. This can be useful to selectively disable some extensions loaded
1221by default, or specified via the C<perl-ext-common> resource. For
1222example, C<default,-selection> will use all the default extension except
1223C<selection>.
1224
1225Extension names can also be followed by an argument in angle brackets
1226(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1227searchable scrollback to Alt/Meta-s). Mentioning the same extension
1228multiple times with different arguments will pass multiple arguments to
1229the extension.
1230
1231Each extension is looked up in the library directories, loaded if
1232necessary, and bound to the current terminal instance.
1233
1234If both of these resources are the empty string, then the perl
1235interpreter will not be initialized. The idea behind two options is that
1236B<perl-ext-common> will be used for extensions that should be available to
1237all instances, while B<perl-ext> is used for specific instances.

1478The RGB cube uses indices 16..79 (16..231) using the following formulas:
1479
1480 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1481 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1484steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of

1504=head2 ALPHA CHANNEL SUPPORT
1505
1506If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1507their act together, rxvt-unicode will do it's own alpha channel management:
1508
1509You can prefix any colour with an opaqueness percentage enclosed in
1510brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1511(0-100) that specifies the opacity of the colour, where C<0> is completely
1512transparent and C<100> is completely opaque. For example, C<[50]red> is a
1513half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1514is the recommended format to specify transparency values, and works with
1515all ways to specify a colour.
1516
1517For complete control, rxvt-unicode also supports
1518C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1519specifications, where the additional C<aaaa> component specifies opacity
1520(alpha) values. The minimum value of C<0000> is completely transparent,
1521while C<ffff> is completely opaque). The two example colours from
1522earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1523C<rgba:0000/ff00/0000/f332>.
1524
1525You probably need to specify B<"-depth 32">, too, to force a visual with
1526alpha channels, and have the luck that your X-server uses ARGB pixel
1527layout, as X is far from just supporting ARGB visuals out of the box, and
1528rxvt-unicode just fudges around.
1529
1530For example, the following selects an almost completely transparent black
1531background, and an almost opaque pink foreground:
1532
1533 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1534
1535When not using a background image, then the interpretation of the
1536alpha channel is up to your compositing manager (most interpret it as
1537transparency of course).
1538
1539When using a background pixmap or pseudo-transparency, then the background
1540colour will always behave as if it were completely transparent (so the
1541background image shows instead), regardless of how it was specified, while
1542other colours will either be transparent as specified (the background
1543image will show through) on servers supporting the RENDER extension, or
1544fully opaque on servers not supporting the RENDER EXTENSION.
1545
1546Please note that due to bugs in Xft, specifying alpha values might result
1547in garbage being displayed when the X-server does not support the RENDER
1548extension.
