1265
1266Extension names can be prefixed with a C<-> sign to prohibit using
1267them. This can be useful to selectively disable some extensions loaded
1268by default, or specified via the C<perl-ext-common> resource. For
1269example, C<default,-selection> will use all the default extension except
1270C<selection>.
1271
1272Extension names can also be followed by an argument in angle brackets
1273(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1274searchable scrollback to Alt/Meta-s). Mentioning the same extension
1275multiple times with different arguments will pass multiple arguments to
1276the extension.
1277
1278Each extension is looked up in the library directories, loaded if
1279necessary, and bound to the current terminal instance.

1281If both of these resources are the empty string, then the perl

1522The following text gives values for the standard 88 colour mode (and
1523values for the 256 colour mode in parentheses).
1524
1525The RGB cube uses indices 16..79 (16..231) using the following formulas:
1526
1527 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1528 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1531steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1532the RGB cube.
1533
1534Together, all those colours implement the 88 (256) colour xterm
1535colours. Only the first 16 can be changed using resources currently, the
1536rest can only be changed via command sequences ("escape codes").

1551=head2 ALPHA CHANNEL SUPPORT
1552
1553If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1554their act together, rxvt-unicode will do its own alpha channel management:
1555
1556You can prefix any colour with an opaqueness percentage enclosed in
1557brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1558(0-100) that specifies the opacity of the colour, where C<0> is completely
1559transparent and C<100> is completely opaque. For example, C<[50]red> is a
1560half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1561is the recommended format to specify transparency values, and works with
1562all ways to specify a colour.
1563
1564For complete control, rxvt-unicode also supports
1565C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1566specifications, where the additional C<aaaa> component specifies opacity
1567(alpha) values. The minimum value of C<0000> is completely transparent,
1568while C<ffff> is completely opaque). The two example colours from
1569earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1570C<rgba:0000/ff00/0000/f332>.
1571
1572You probably need to specify B<"-depth 32">, too, to force a visual with
1573alpha channels, and have the luck that your X-server uses ARGB pixel
1574layout, as X is far from just supporting ARGB visuals out of the box, and
1575rxvt-unicode just fudges around.
1576
1577For example, the following selects an almost completely transparent black
1578background, and an almost opaque pink foreground:
1579
1580 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1581
1582When not using a background image, then the interpretation of the
1583alpha channel is up to your compositing manager (most interpret it as
1584transparency of course).
1585
1586When using a background pixmap or pseudo-transparency, then the background
1587colour will always behave as if it were completely transparent (so the
1588background image shows instead), regardless of how it was specified, while
1589other colours will either be transparent as specified (the background
1590image will show through) on servers supporting the RENDER extension, or
1591fully opaque on servers not supporting the RENDER EXTENSION.
1592
1593Please note that due to bugs in Xft, specifying alpha values might result
1594in garbage being displayed when the X-server does not support the RENDER
1595extension.
