506Here is a short Gtk2-perl snippet that illustrates how this option can be

508
509 my $rxvt = new Gtk2::Socket;
510 $rxvt->signal_connect_after (realize => sub {

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>):

1205If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1206is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1207manpage. For example, the F<selection> extension (activated via

1212Due the the large number of modifier combinations, a defined key mapping
1213will match if I<at least> the specified identifiers are being set, and
1214no other key mappings with those and more bits are being defined. That
1215means that defining a key map for C<a> will automatically provide
1216definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1217mappings themselves.
1218
1219Unfortunately, this will override built-in key mappings. For example
1220if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1221C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1222user-defined keymap using the C<builtin:> replacement:
1223
1224 URxvt.keysym.Insert: <my insert key sequence>
1225 URxvt.keysym.S-Insert: builtin:
1226
1227The first line defines a mapping for C<Insert> and I<any> combination
1228of modifiers. The second line re-establishes the default mapping for
1229C<Shift-Insert>.

1507The following text gives values for the standard 88 colour mode (and
1508values for the 256 colour mode in parentheses).
1509
1510The RGB cube uses indices 16..79 (16..231) using the following formulas:
1511
1512 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1513 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15
1514
1515The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1516steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1517the RGB cube.
1518
1519Together, all those colours implement the 88 (256) colour xterm
1520colours. Only the first 16 can be changed using resources currently, the
1521rest can only be changed via command sequences ("escape codes").

1536=head2 ALPHA CHANNEL SUPPORT
1537
1538If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1539their act together, rxvt-unicode will do it's own alpha channel management:
1540
1541You can prefix any colour with an opaqueness percentage enclosed in
1542brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1543(0-100) that specifies the opacity of the colour, where C<0> is completely
1544transparent and C<100> is completely opaque. For example, C<[50]red> is a
1545half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1546is the recommended format to specify transparency values, and works with
1547all ways to specify a colour.
1548
1549For complete control, rxvt-unicode also supports
1550C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1551specifications, where the additional C<aaaa> component specifies opacity
1552(alpha) values. The minimum value of C<0000> is completely transparent,
1553while C<ffff> is completely opaque). The two example colours from
1554earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1555C<rgba:0000/ff00/0000/f332>.
1556
1557You probably need to specify B<"-depth 32">, too, to force a visual with
1558alpha channels, and have the luck that your X-server uses ARGB pixel
1559layout, as X is far from just supporting ARGB visuals out of the box, and
1560rxvt-unicode just fudges around.
1561
1562For example, the following selects an almost completely transparent black
1563background, and an almost opaque pink foreground:
1564
1565 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1566
1567When not using a background image, then the interpretation of the
1568alpha channel is up to your compositing manager (most interpret it as
1569transparency of course).
1570
1571When using a background pixmap or pseudo-transparency, then the background
1572colour will always behave as if it were completely transparent (so the
1573background image shows instead), regardless of how it was specified, while
1574other colours will either be transparent as specified (the background
1575image will show through) on servers supporting the RENDER extension, or
1576fully opaque on servers not supporting the RENDER EXTENSION.
1577
1578Please note that due to bugs in Xft, specifying alpha values might result
1579in garbage being displayed when the X-server does not support the RENDER
1580extension.
