519Here is a short Gtk2-perl snippet that illustrates how this option can be
520used (a longer example is in F<doc/embed>):
521
522 my $rxvt = new Gtk2::Socket;
523 $rxvt->signal_connect_after (realize => sub {

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

1196If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1197is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1198manpage. For example, the F<selection> extension (activated via
1199C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1200
1201 URxvt.keysym.M-C-c: perl:selection:rot13
1202
1203Due the the large number of modifier combinations, a defined key mapping
1204will match if I<at least> the specified identifiers are being set, and
1205no other key mappings with those and more bits are being defined. That
1206means that defining a key map for C<a> will automatically provide
1207definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1208mappings themselves.
1209
1210Unfortunately, this will override built-in key mappings. For example
1211if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1212C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1213user-defined keymap using the C<builtin:> replacement:
1214
1215 URxvt.keysym.Insert: <my insert key sequence>
1216 URxvt.keysym.S-Insert: builtin:
1217
1218The first line defines a mapping for C<Insert> and I<any> combination
1219of modifiers. The second line re-establishes the default mapping for
1220C<Shift-Insert>.

1239Comma-separated list(s) of perl extension scripts (default: C<default>) to

1241
1242Extension names can be prefixed with a C<-> sign to prohibit using
1243them. This can be useful to selectively disable some extensions loaded
1244by default, or specified via the C<perl-ext-common> resource. For
1245example, C<default,-selection> will use all the default extension except
1246C<selection>.
1247
1248Extension names can also be followed by an argument in angle brackets
1249(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1250searchable scrollback to Alt/Meta-s). Mentioning the same extension
1251multiple times with different arguments will pass multiple arguments to
1252the extension.
1253
1254Each extension is looked up in the library directories, loaded if
1255necessary, and bound to the current terminal instance.
1256
1257If both of these resources are the empty string, then the perl
1258interpreter will not be initialized. The idea behind two options is that
1259B<perl-ext-common> will be used for extensions that should be available to

1498The following text gives values for the standard 88 colour mode (and
1499values for the 256 colour mode in parentheses).

1501The RGB cube uses indices 16..79 (16..231) using the following formulas:
1502
1503 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1504 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15
1505
1506The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1507steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1508the RGB cube.
1509
1510Together, all those colours implement the 88 (256) colour xterm
1511colours. Only the first 16 can be changed using resources currently, the
1512rest can only be changed via command sequences ("escape codes").

1527=head2 ALPHA CHANNEL SUPPORT
1528
1529If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1530their act together, rxvt-unicode will do it's own alpha channel management:
1531
1532You can prefix any colour with an opaqueness percentage enclosed in
1533brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1534(0-100) that specifies the opacity of the colour, where C<0> is completely
1535transparent and C<100> is completely opaque. For example, C<[50]red> is a
1536half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1537is the recommended format to specify transparency values, and works with
1538all ways to specify a colour.
1539
1540For complete control, rxvt-unicode also supports
1541C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1542specifications, where the additional C<aaaa> component specifies opacity
1543(alpha) values. The minimum value of C<0000> is completely transparent,
1544while C<ffff> is completely opaque). The two example colours from
1545earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1546C<rgba:0000/ff00/0000/f332>.
1547
1548You probably need to specify B<"-depth 32">, too, to force a visual with
1549alpha channels, and have the luck that your X-server uses ARGB pixel
1550layout, as X is far from just supporting ARGB visuals out of the box, and
1551rxvt-unicode just fudges around.
1552
1553For example, the following selects an almost completely transparent black
1554background, and an almost opaque pink foreground:
1555
1556 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1557
1558When not using a background image, then the interpretation of the
1559alpha channel is up to your compositing manager (most interpret it as
1560transparency of course).
1561
1562When using a background pixmap or pseudo-transparency, then the background
1563colour will always behave as if it were completely transparent (so the
1564background image shows instead), regardless of how it was specified, while
1565other colours will either be transparent as specified (the background
1566image will show through) on servers supporting the RENDER extension, or
1567fully opaque on servers not supporting the RENDER EXTENSION.
1568
1569Please note that due to bugs in Xft, specifying alpha values might result
1570in garbage being displayed when the X-server does not support the RENDER
1571extension.
