1228Comma-separated list(s) of perl extension scripts (default: C<default>) to
1229use in this terminal instance; option B<-pe>.
1230
1231Extension names can be prefixed with a C<-> sign to prohibit using
1232them. This can be useful to selectively disable some extensions loaded
1233by default, or specified via the C<perl-ext-common> resource. For
1234example, C<default,-selection> will use all the default extension except
1235C<selection>.
1236
1237Extension names can also be followed by an argument in angle brackets
1238(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1239searchable scrollback to Alt/Meta-s). Mentioning the same extension
1240multiple times with different arguments will pass multiple arguments to
1241the extension.
1242
1243Each extension is looked up in the library directories, loaded if
1244necessary, and bound to the current terminal instance.
1245
1246If both of these resources are the empty string, then the perl
1247interpreter will not be initialized. The idea behind two options is that
1248B<perl-ext-common> will be used for extensions that should be available to

1490The RGB cube uses indices 16..79 (16..231) using the following formulas:
1491
1492 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1493 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1496steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1497the RGB cube.

1516=head2 ALPHA CHANNEL SUPPORT
1517
1518If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1519their act together, rxvt-unicode will do it's own alpha channel management:
1520
1521You can prefix any colour with an opaqueness percentage enclosed in
1522brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1523(0-100) that specifies the opacity of the colour, where C<0> is completely
1524transparent and C<100> is completely opaque. For example, C<[50]red> is a
1525half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1526is the recommended format to specify transparency values, and works with
1527all ways to specify a colour.
1528
1529For complete control, rxvt-unicode also supports
1530C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1531specifications, where the additional C<aaaa> component specifies opacity
1532(alpha) values. The minimum value of C<0000> is completely transparent,
1533while C<ffff> is completely opaque). The two example colours from
1534earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1535C<rgba:0000/ff00/0000/f332>.
1536
1537You probably need to specify B<"-depth 32">, too, to force a visual with
1538alpha channels, and have the luck that your X-server uses ARGB pixel
1539layout, as X is far from just supporting ARGB visuals out of the box, and
1540rxvt-unicode just fudges around.
1541
1542For example, the following selects an almost completely transparent black
1543background, and an almost opaque pink foreground:
1544
1545 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1546
1547When not using a background image, then the interpretation of the
1548alpha channel is up to your compositing manager (most interpret it as
1549transparency of course).
1550
1551When using a background pixmap or pseudo-transparency, then the background
1552colour will always behave as if it were completely transparent (so the
1553background image shows instead), regardless of how it was specified, while
1554other colours will either be transparent as specified (the background
1555image will show through) on servers supporting the RENDER extension, or
1556fully opaque on servers not supporting the RENDER EXTENSION.
1557
1558Please note that due to bugs in Xft, specifying alpha values might result
1559in garbage being displayed when the X-server does not support the RENDER
1560extension.
