27=head1 RXVT-UNICODE VS. RXVT
28
29Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
30internally. That means it can store and display most scripts in the
31world. Being a terminal emulator, however, some things are very difficult,
32especially cursive scripts such as arabic, vertically written scripts
33like mongolian or scripts requiring extremely complex combining rules,
34like tibetan or devanagari. Don't expect pretty output when using these
35scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
36fine, though. A somewhat difficult case are right-to-left scripts, such
37as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
38belong in the application, not the terminal emulator (too many things --
39such as cursor-movement while editing -- break otherwise), but that might
40change.
41
42If you are looking for a terminal that supports more exotic scripts, let
43me recommend C<mlterm>, which is a very user friendly, lean and clean
44terminal emulator. In fact, the reason rxvt-unicode was born was solely
45because the author couldn't get C<mlterm> to use one font for latin1 and
46another for japanese.
47
48Therefore another design rationale was the use of multiple fonts to
49display characters: The idea of a single unicode font which many other
50programs force onto its users never made sense to me: You should be able
51to choose any font for any script freely.
52
53Apart from that, rxvt-unicode is also much better internationalised than
54its predecessor, supports things such as XFT and ISO 14755 that are handy
55in i18n-environments, is faster, and has a lot bugs less than the original
56rxvt. This all in addition to dozens of other small improvements.
57
58It is still faithfully following the original rxvt idea of being lean
59and nice on resources: for example, you can still configure rxvt-unicode
60without most of its features to get a lean binary. It also comes with
61a client/daemon pair that lets you open any number of terminal windows
62from within a single process, which makes startup time very fast and
63drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
64@@RXVT_NAME@@c(1) (client).
65
66It also makes technical information about escape sequences (which have
67been extended) more accessible: see @@RXVT_NAME@@(7) for technical
68reference documentation (escape sequences etc.).

463descriptors passed to it (except for stdin/out/err, of course), so you
464can use file descriptors to communicate with the programs within the
465terminal. This works regardless of whether the C<-embed> option was used or
466not.
467
468Here is a short Gtk2-perl snippet that illustrates how this option can be
469used (a longer example is in F<doc/embed>):
470
471 my $rxvt = new Gtk2::Socket;
472 $rxvt->signal_connect_after (realize => sub {
473 my $xid = $_[0]->window->get_xid;
474 system "@@RXVT_NAME@@ -embed $xid &";
475 });
476
477=item B<-pty-fd> I<file descriptor>
478
479Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
480pair but instead use the given file descriptor as the tty master. This is
481useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
482without having to run a program within it.
483
484If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
485entries and will not tinker with pty/tty permissions - you have to do that
486yourself if you want that.
487
488As an extremely special case, specifying C<-1> will completely suppress
489pty/tty operations, which is probably only useful in conjunction with some
490perl extension that manages the terminal.
491
492Here is a example in perl that illustrates how this option can be used (a
493longer example is in F<doc/pty-fd>):
494
495 use IO::Pty;
496 use Fcntl;
497
498 my $pty = new IO::Pty;
499 fcntl $pty, F_SETFD, 0; # clear close-on-exec
500 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
501 close $pty;
502
503 # now communicate with rxvt
504 my $slave = $pty->slave;
505 while (<$slave>) { print $slave "got <$_>\n" }

704omitted. This resource is only available when compiled with 1054terminal scroll up or down the way you want it, or any other thing an
705KEYSYM_RESOURCE. 1055extension might provide.
1056
1057The key combination that triggers the action, I<sym>, has the following format:
1058
1059 (modifiers-)key
1060
1061Where I<modifiers> can be any combination of B<ISOLevel3>, B<AppKeypad>,
1062B<Control>, B<NumLock>, B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>,
1063B<Mod3>, B<Mod4>, B<Mod5>, and the abbreviated B<I>, B<K>, B<C>, B<N>,
1064B<S>, B<M>, B<A>, B<L>, B<1>, B<2>, B<3>, B<4>, B<5>.
1065
1066The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1067whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1068keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1069current application keymap mode state.
1070
1071Due the the large number of modifier combinations, a key mapping will
1072match if I<at least> the specified identifiers are being set, and no other
1073key mappings with those and more bits are being defined. That means that
1074defining a mapping for C<a> will automatically provide definitions for
1075C<Meta-a>, C<Shift-a> and so on, unless some of those are defined mappings
1076themselves. See the C<builtin:> action, below, for a way to work around
1077this when this is a problem.
1078
1079The spelling of I<key> depends on your implementation of X. An easy way to
1080find a key name is to use the B<xev>(1) command. You can find a list by
1081looking for the C<XK_> macros in the B<X11/keysymdef.h> include file (omit
1082the C<XK_> prefix). Alternatively you can specify I<key> by its hex keysym
1083value (B<0x0000 - 0xFFFF>).
1084
1085As with any resource value, the I<action> string may contain backslash
1086escape sequences (C<\n>: newline, C<\\>: backslash, C<\000>: octal
1087number), see RESOURCES in C<man 7 X> for further details.
1088
1089An action starts with an action prefix that selects a certain type
1090of action, followed by a colon. An action strings without colons is
1091interpreted as a literal string to pass to the tty (as if they were
1092prefixed with C<string:>).
1093
1094The following action prefixes are known - extensions can provide
1095additional prefixes:
1096
1097=over 4
1098
1099=item string:STRING
1100
1101If the I<action> starts with C<string:> (or otherwise contains no colons),
1102then the remaining C<STRING> will be passed to the program running in the
1103terminal. For example, you could replace whatever Shift-Tab outputs by the
1104string C<echo rm -rf /> followed by a newline:
1105
1106 URxvt.keysym.Shift-Tab: string:echo rm -rf /\n
1107
1108This could in theory be used to completely redefine your keymap.
1109
1110=item command:STRING
1111
1112If I<action> takes the form of C<command:STRING>, the specified B<STRING>
1113is interpreted and executed as @@RXVT_NAME@@'s control sequence (basically
1114the opposite of C<string:> - instead of sending it to the program running
1115in the terminal, it will be treated as if it were program output). This is
1116most useful to feed command sequences into @@RXVT_NAME@@.
1117
1118For example the following means "change the current locale to C<zh_CN.GBK>
1119when Control-Meta-c is being pressed":
1120
1121 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1122
1123The following example will map Control-Meta-1 and Control-Meta-2 to
1124the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1125font-switching at runtime:
1126
1127 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1128 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1129
1130Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1131info):
1132
1133 URxvt.keysym.M-C-3: command:\033[8;25;80t
1134 URxvt.keysym.M-C-4: command:\033[8;48;110t
1135
1136=item builtin:
1137
1138The builtin action is the action that @@RXVT_NAME@@ would execute if no
1139key binding existed for the key combination. The obvious use is to undo
1140the effect of existing bindings. The not so obvious use is to reinstate
1141bindings when another binding overrides too many modifiers.
1142
1143For example if you overwrite the C<Insert> key you will disable
1144@@RXVT_NAME@@'s C<Shift-Insert> mapping. To re-enable that, you can poke
1145"holes" into the user-defined keymap using the C<builtin:> replacement:
1146
1147 URxvt.keysym.Insert: <my insert key sequence>
1148 URxvt.keysym.S-Insert: builtin:
1149
1150The first line defines a mapping for C<Insert> and I<any> combination
1151of modifiers. The second line re-establishes the default mapping for
1152C<Shift-Insert>.
1153
1154=item builtin-string:
1155
1156This action is mainly useful to restore string mappings for keys that
1157have predefined actions in @@RXVT_NAME@@. The exact semantics are a bit
1158difficult to explain - basically, this action will send the string to the
1159application that would be sent if @@RXVT_NAME@@ wouldn't have a built-in
1160action for it.
1161
1162An example might make it clearer: @@RXVT_NAME@@ normally pastes the
1163selection when you press C<Shift-Insert>. With the following bindings, it
1164would instead emit the (undocumented, but what applications running in the
1165terminal might expect) sequence C<ESC [ 2 $> instead:
1166
1167 URxvt.keysym.S-Insert: builtin-string:
1168 URxvt.keysym.C-S-Insert: builtin:
1169
1170The first line disables the paste functionality for that key
1171combination, and the second reinstates the default behaviour for
1172C<Control-Shift-Insert>, which would otherwise be overridden.
1173
1174Similarly, to let applications gain access to the C<C-M-c> (copy to
1175clipboard) and C<C-M-v> (paste clipboard) key combination, you can do
1176this:
1177
1178 URxvt.keysym.C-S-c: builtin-string:
1179 URxvt.keysym.C-S-v: builtin-string:
1180
1181=item EXTENSION:STRING
1182
1183An action of this form passes the B<STRING> to the @@RXVT_NAME@@perl(3)
1184extension of the same name. The extension will be loaded automatically if
1185neccessary.
1186
1187Not all extensions define key actions, but popular extensions that do
1188include the I<selection> and I<matcher> extensions (documented in their
1189own manpages, @@RXVT_NAME@@-selection(1) and @@RXVT_NAME@@-matcher(1),
1190respectively).
1191
1192From the silly examples department, this will rot13-"encrypt"
1193@@RXVT_NAME@@'s selection when Alt-Control-c is pressed on typical PC
1194keyboards:
1195

1198=item perl:STRING *DEPRECATED*

1200This is a deprecated way of passing key mappings to perl extensions. It is
1201still supported, but should not be used anymore.

1209Comma-separated list(s) of perl extension scripts (default: C<default>) to
1210use in this terminal instance; option B<-pe>.
1211
1212Extension names can be prefixed with a C<-> sign to prohibit using
1213them. This can be useful to selectively disable some extensions loaded
1214by default, or specified via the C<perl-ext-common> resource. For
1215example, C<default,-selection> will use all the default extensions except
1216C<selection>.
1217
1218The default set includes the C<selection>, C<option-popup>,
1219C<selection-popup> and C<readline> extensions, any extensions that define
1220keybindings via C<BINDING> meta comments, extensions loaded because
1221their resources/commandline switches were used, and extensions which are
1222mentioned in B<keysym> resources.
1223
1224Each extension is looked up in the library directories, loaded if
1225necessary, and bound to the current terminal instance. When the library
1226search path contains multiple extension files of the same name, then the
1227first one found will be used.
1228
1229If both of these resources are the empty string, then the perl interpreter
1230will not be initialized. The rationale for having two options is that
1231B<perl-ext-common> will be used for extensions that should be available to
1232all instances, while B<perl-ext> is used for specific instances.

765=head1 ISO 14755 SUPPORT 1482=head1 ISO 14755 SUPPORT
766 1483
767Partial ISO 14755-support is implemented. that means that pressing 1484ISO 14755 is a standard for entering and viewing unicode characters
1485and character codes using the keyboard. It consists of 4 parts. The
1486first part is available if rxvt-unicode has been compiled with
1487C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1488with C<--enable-iso14755>.

777key. 1495
1496Start by pressing and holding both C<Control> and C<Shift>, then enter
1497hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1498commit the character as if it were typed directly. While holding down
1499C<Control> and C<Shift> you can also enter multiple characters by pressing
1500C<Space>, which will commit the current character and lets you start a new
1501one.
1502
1503As an example of use, imagine a business card with a japanese e-mail
1504address, which you cannot type. Fortunately, the card has the e-mail
1505address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1506by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1507followed by releasing the modifier keys.
1508
1509=item * 5.2: Keyboard symbols entry method
1510
1511This mode lets you input characters representing the keycap symbols of
1512your keyboard, if representable in the current locale encoding.
1513
1514Start by pressing C<Control> and C<Shift> together, then releasing
1515them. The next special key (cursor keys, home etc.) you enter will not
1516invoke its usual function but instead will insert the corresponding
1517keycap symbol. The symbol will only be entered when the key has been
1518released, otherwise pressing e.g. C<Shift> would enter the symbol for
1519C<ISO Level 2 Switch>, although your intention might have been to enter a
1520reverse tab (Shift-Tab).
1521
1522=item * 5.3: Screen-selection entry method
1523
1524While this is implemented already (it's basically the selection
1525mechanism), it could be extended by displaying a unicode character map.
1526
1527=item * 5.4: Feedback method for identifying displayed characters for later input
1528
1529This method lets you display the unicode character code associated with
1530characters already displayed.
1531
1532You enter this mode by holding down C<Control> and C<Shift> together, then
1533pressing and holding the left mouse button and moving around. The unicode
1534hex code(s) (it might be a combining character) of the character under the
1535pointer is displayed until you release C<Control> and C<Shift>.
1536
1537In addition to the hex codes it will display the font used to draw this
1538character - due to implementation reasons, characters combined with
1539combining characters, line drawing characters and unknown characters will
1540always be drawn using the built-in support font.

1592The following text gives values for the standard 88 colour mode (and
1593values for the 256 colour mode in parentheses).
1594
1595The RGB cube uses indices 16..79 (16..231) using the following formulas:
1596
1597 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1598 index_256 = (r * 6 + g) * 6 + b + 16 # r, g, b = 0..5
1599
1600The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1601steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
1602the RGB cube.
1603
1604Together, all those colours implement the 88 (256) colour xterm
1605colours. Only the first 16 can be changed using resources currently, the
1606rest can only be changed via command sequences ("escape codes").

1621=head2 ALPHA CHANNEL SUPPORT
1622
1623If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1624their act together, rxvt-unicode will do its own alpha channel management:
1625
1626You can prefix any colour with an opaqueness percentage enclosed in
1627brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1628(0-100) that specifies the opacity of the colour, where C<0> is completely
1629transparent and C<100> is completely opaque. For example, C<[50]red> is a
1630half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1631is the recommended format to specify transparency values, and works with
1632all ways to specify a colour.
1633
1634For complete control, rxvt-unicode also supports
1635C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1636specifications, where the additional C<aaaa> component specifies opacity
1637(alpha) values. The minimum value of C<0000> is completely transparent,
1638while C<ffff> is completely opaque). The two example colours from
1639earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1640C<rgba:0000/ff00/0000/f332>.
1641
1642You probably need to specify B<"-depth 32">, too, to force a visual with
1643alpha channels, and have the luck that your X-server uses ARGB pixel
1644layout, as X is far from just supporting ARGB visuals out of the box, and
1645rxvt-unicode just fudges around.
1646
1647For example, the following selects an almost completely transparent black
1648background, and an almost opaque pink foreground:
1649
1650 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1651
1652When not using a background image, then the interpretation of the
1653alpha channel is up to your compositing manager (most interpret it as
1654transparency of course).
1655
1656When using a background pixmap or pseudo-transparency, then the background
1657colour will always behave as if it were completely transparent (so the
1658background image shows instead), regardless of how it was specified, while
1659other colours will either be transparent as specified (the background
1660image will show through) on servers supporting the RENDER extension, or
1661fully opaque on servers not supporting the RENDER EXTENSION.
1662
1663Please note that due to bugs in Xft, specifying alpha values might result
1664in garbage being displayed when the X-server does not support the RENDER
1665extension.
