1136Comma-separated list(s) of perl extension scripts (default: C<default>) to
1137use in this terminal instance; option B<-pe>.
1138
1139Extension names can be prefixed with a C<-> sign to prohibit using
1140them. This can be useful to selectively disable some extensions loaded
1141by default, or specified via the C<perl-ext-common> resource. For
1142example, C<default,-selection> will use all the default extension except
1143C<selection>.
1144
1145Extension names can also be followed by an argument in angle brackets
1146(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1147searchable scrollback to Alt/Meta-s). Mentioning the same extension
1148multiple times with different arguments will pass multiple arguments to
1149the extension.
1150
1151Each extension is looked up in the library directories, loaded if
1152necessary, and bound to the current terminal instance.
1153
1154If both of these resources are the empty string, then the perl
1155interpreter will not be initialized. The idea behind two options is that
1156B<perl-ext-common> will be used for extensions that should be available to

1512The RGB cube uses indices 16..79 (16..231) using the following formulas:
1513
1514 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1515 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1518steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1519the RGB cube.
1520
1521Together, all those colours implement the 88 (256) colour xterm

1538=head2 ALPHA CHANNEL SUPPORT
1539
1540If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1541their act together, rxvt-unicode will do its own alpha channel management:
1542
1543You can prefix any colour with an opaqueness percentage enclosed in
1544brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1545(0-100) that specifies the opacity of the colour, where C<0> is completely
1546transparent and C<100> is completely opaque. For example, C<[50]red> is a
1547half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1548is the recommended format to specify transparency values, and works with
1549all ways to specify a colour.
1550
1551For complete control, rxvt-unicode also supports
1552C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1553specifications, where the additional C<aaaa> component specifies opacity
1554(alpha) values. The minimum value of C<0000> is completely transparent,
1555while C<ffff> is completely opaque). The two example colours from
1556earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1557C<rgba:0000/ff00/0000/f332>.
1558
1559You probably need to specify B<"-depth 32">, too, to force a visual with
1560alpha channels, and have the luck that your X-server uses ARGB pixel
1561layout, as X is far from just supporting ARGB visuals out of the box, and
1562rxvt-unicode just fudges around.
1563
1564For example, the following selects an almost completely transparent black
1565background, and an almost opaque pink foreground:
1566
1567 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1568
1569When not using a background image, then the interpretation of the
1570alpha channel is up to your compositing manager (most interpret it as
1571transparency of course).
1572
1573When using a background pixmap or pseudo-transparency, then the background
1574colour will always behave as if it were completely transparent (so the
1575background image shows instead), regardless of how it was specified, while
1576other colours will either be transparent as specified (the background
1577image will show through) on servers supporting the RENDER extension, or
1578fully opaque on servers not supporting the RENDER EXTENSION.
1579
1580Please note that due to bugs in Xft, specifying alpha values might result
1581in garbage being displayed when the X-server does not support the RENDER
1582extension.
