1276
1277Extension names can be prefixed with a C<-> sign to prohibit using
1278them. This can be useful to selectively disable some extensions loaded
1279by default, or specified via the C<perl-ext-common> resource. For
1280example, C<default,-selection> will use all the default extension except
1281C<selection>.
1282
1283Extension names can also be followed by an argument in angle brackets
1284(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1285searchable scrollback to Alt/Meta-s). Mentioning the same extension
1286multiple times with different arguments will pass multiple arguments to
1287the extension.
1288
1289Each extension is looked up in the library directories, loaded if
1290necessary, and bound to the current terminal instance.
1291
1292If both of these resources are the empty string, then the perl
1293interpreter will not be initialized. The idea behind two options is that

1533The following text gives values for the standard 88 colour mode (and
1534values for the 256 colour mode in parentheses).
1535
1536The RGB cube uses indices 16..79 (16..231) using the following formulas:
1537
1538 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1539 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1542steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1543the RGB cube.
1544
1545Together, all those colours implement the 88 (256) colour xterm

1562=head2 ALPHA CHANNEL SUPPORT
1563
1564If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1565their act together, rxvt-unicode will do it's own alpha channel management:
1566
1567You can prefix any colour with an opaqueness percentage enclosed in
1568brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1569(0-100) that specifies the opacity of the colour, where C<0> is completely
1570transparent and C<100> is completely opaque. For example, C<[50]red> is a
1571half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1572is the recommended format to specify transparency values, and works with
1573all ways to specify a colour.
1574
1575For complete control, rxvt-unicode also supports
1576C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1577specifications, where the additional C<aaaa> component specifies opacity
1578(alpha) values. The minimum value of C<0000> is completely transparent,
1579while C<ffff> is completely opaque). The two example colours from
1580earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1581C<rgba:0000/ff00/0000/f332>.
1582
1583You probably need to specify B<"-depth 32">, too, to force a visual with
1584alpha channels, and have the luck that your X-server uses ARGB pixel
1585layout, as X is far from just supporting ARGB visuals out of the box, and
1586rxvt-unicode just fudges around.
1587
1588For example, the following selects an almost completely transparent black
1589background, and an almost opaque pink foreground:
1590
1591 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1592
1593When not using a background image, then the interpretation of the
1594alpha channel is up to your compositing manager (most interpret it as
1595transparency of course).
1596
1597When using a background pixmap or pseudo-transparency, then the background
1598colour will always behave as if it were completely transparent (so the
1599background image shows instead), regardless of how it was specified, while
1600other colours will either be transparent as specified (the background
1601image will show through) on servers supporting the RENDER extension, or
1602fully opaque on servers not supporting the RENDER EXTENSION.
1603
1604Please note that due to bugs in Xft, specifying alpha values might result
1605in garbage being displayed when the X-server does not support the RENDER
1606extension.
