1275Comma-separated list(s) of perl extension scripts (default: C<default>) to
1276use in this terminal instance; option B<-pe>.
1277
1278Extension names can be prefixed with a C<-> sign to prohibit using
1279them. This can be useful to selectively disable some extensions loaded
1280by default, or specified via the C<perl-ext-common> resource. For
1281example, C<default,-selection> will use all the default extension except
1282C<selection>.
1283
1284Extension names can also be followed by an argument in angle brackets
1285(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1286searchable scrollback to Alt/Meta-s). Mentioning the same extension
1287multiple times with different arguments will pass multiple arguments to
1288the extension.
1289
1290Each extension is looked up in the library directories, loaded if
1291necessary, and bound to the current terminal instance.
1292
1293If both of these resources are the empty string, then the perl
1294interpreter will not be initialized. The idea behind two options is that
1295B<perl-ext-common> will be used for extensions that should be available to

1534The following text gives values for the standard 88 colour mode (and
1535values for the 256 colour mode in parentheses).
1536
1537The RGB cube uses indices 16..79 (16..231) using the following formulas:
1538
1539 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1540 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1543steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1544the RGB cube.
1545
1546Together, all those colours implement the 88 (256) colour xterm
1547colours. Only the first 16 can be changed using resources currently, the
1548rest can only be changed via command sequences ("escape codes").

1563=head2 ALPHA CHANNEL SUPPORT
1564
1565If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1566their act together, rxvt-unicode will do its own alpha channel management:
1567
1568You can prefix any colour with an opaqueness percentage enclosed in
1569brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1570(0-100) that specifies the opacity of the colour, where C<0> is completely
1571transparent and C<100> is completely opaque. For example, C<[50]red> is a
1572half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1573is the recommended format to specify transparency values, and works with
1574all ways to specify a colour.
1575
1576For complete control, rxvt-unicode also supports
1577C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1578specifications, where the additional C<aaaa> component specifies opacity
1579(alpha) values. The minimum value of C<0000> is completely transparent,
1580while C<ffff> is completely opaque). The two example colours from
1581earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1582C<rgba:0000/ff00/0000/f332>.
1583
1584You probably need to specify B<"-depth 32">, too, to force a visual with
1585alpha channels, and have the luck that your X-server uses ARGB pixel
1586layout, as X is far from just supporting ARGB visuals out of the box, and
1587rxvt-unicode just fudges around.
1588
1589For example, the following selects an almost completely transparent black
1590background, and an almost opaque pink foreground:
1591
1592 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1593
1594When not using a background image, then the interpretation of the
1595alpha channel is up to your compositing manager (most interpret it as
1596transparency of course).
1597
1598When using a background pixmap or pseudo-transparency, then the background
1599colour will always behave as if it were completely transparent (so the
1600background image shows instead), regardless of how it was specified, while
1601other colours will either be transparent as specified (the background
1602image will show through) on servers supporting the RENDER extension, or
1603fully opaque on servers not supporting the RENDER EXTENSION.
1604
1605Please note that due to bugs in Xft, specifying alpha values might result
1606in garbage being displayed when the X-server does not support the RENDER
1607extension.
