1261
1262Extension names can be prefixed with a C<-> sign to prohibit using
1263them. This can be useful to selectively disable some extensions loaded
1264by default, or specified via the C<perl-ext-common> resource. For
1265example, C<default,-selection> will use all the default extension except
1266C<selection>.
1267
1268Extension names can also be followed by an argument in angle brackets
1269(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1270searchable scrollback to Alt/Meta-s). Mentioning the same extension
1271multiple times with different arguments will pass multiple arguments to
1272the extension.
1273
1274Each extension is looked up in the library directories, loaded if
1275necessary, and bound to the current terminal instance.
1276
1277If both of these resources are the empty string, then the perl
1278interpreter will not be initialized. The idea behind two options is that

1518The following text gives values for the standard 88 colour mode (and
1519values for the 256 colour mode in parentheses).
1520
1521The RGB cube uses indices 16..79 (16..231) using the following formulas:
1522
1523 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1524 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15
1525
1526The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1527steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1528the RGB cube.
1529
1530Together, all those colours implement the 88 (256) colour xterm
1531colours. Only the first 16 can be changed using resources currently, the
1532rest can only be changed via command sequences ("escape codes").

1547=head2 ALPHA CHANNEL SUPPORT
1548
1549If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1550their act together, rxvt-unicode will do its own alpha channel management:
1551
1552You can prefix any colour with an opaqueness percentage enclosed in
1553brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1554(0-100) that specifies the opacity of the colour, where C<0> is completely
1555transparent and C<100> is completely opaque. For example, C<[50]red> is a
1556half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1557is the recommended format to specify transparency values, and works with
1558all ways to specify a colour.
1559
1560For complete control, rxvt-unicode also supports
1561C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1562specifications, where the additional C<aaaa> component specifies opacity
1563(alpha) values. The minimum value of C<0000> is completely transparent,
1564while C<ffff> is completely opaque). The two example colours from
1565earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1566C<rgba:0000/ff00/0000/f332>.
1567
1568You probably need to specify B<"-depth 32">, too, to force a visual with
1569alpha channels, and have the luck that your X-server uses ARGB pixel
1570layout, as X is far from just supporting ARGB visuals out of the box, and
1571rxvt-unicode just fudges around.
1572
1573For example, the following selects an almost completely transparent black
1574background, and an almost opaque pink foreground:
1575
1576 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1577
1578When not using a background image, then the interpretation of the
1579alpha channel is up to your compositing manager (most interpret it as
1580transparency of course).
1581
1582When using a background pixmap or pseudo-transparency, then the background
1583colour will always behave as if it were completely transparent (so the
1584background image shows instead), regardless of how it was specified, while
1585other colours will either be transparent as specified (the background
1586image will show through) on servers supporting the RENDER extension, or
1587fully opaque on servers not supporting the RENDER EXTENSION.
1588
1589Please note that due to bugs in Xft, specifying alpha values might result
1590in garbage being displayed when the X-server does not support the RENDER
1591extension.
