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.).

484
485Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
486which enables applications to easily embed a terminal.
487
488Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
489shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
490quite a bit, so don't expect it to keep some specific state. It's best to
491create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
492
493The window will not be destroyed when @@RXVT_NAME@@ exits.
494
495It might be useful to know that @@RXVT_NAME@@ will not close file
496descriptors passed to it (except for stdin/out/err, of course), so you
497can use file descriptors to communicate with the programs within the
498terminal. This works regardless of whether the C<-embed> option was used or
499not.
500
501Here is a short Gtk2-perl snippet that illustrates how this option can be
502used (a longer example is in F<doc/embed>):
503
504 my $rxvt = new Gtk2::Socket;
505 $rxvt->signal_connect_after (realize => sub {
506 my $xid = $_[0]->window->get_xid;
507 system "@@RXVT_NAME@@ -embed $xid &";
508 });

511
512Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
513pair but instead use the given file descriptor as the tty master. This is
514useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
515without having to run a program within it.
516
517If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
518entries and will not tinker with pty/tty permissions - you have to do that
519yourself if you want that.
520
521As an extremely special case, specifying C<-1> will completely suppress
522pty/tty operations, which is probably only useful in conjunction with some
523perl extension that manages the terminal.
524
525Here is a example in perl that illustrates how this option can be used (a
526longer example is in F<doc/pty-fd>):
527
528 use IO::Pty;
529 use Fcntl;
530
531 my $pty = new IO::Pty;

701omitted. This resource is only available when compiled with 1121
702KEYSYM_RESOURCE. 1122The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1123any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1124B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1125and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1126B<2>, B<3>, B<4>, B<5>.
1127
1128The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1129whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1130keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1131current application keymap mode state.
1132
1133The spellings of I<key> can be obtained by using B<xev>(1) command or
1134searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1135omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1136keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1137performed in an exact manner; however, the closest match is assured.
1138
1139I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1140number), see RESOURCES in C<man 7 X> for futher details.
1141
1142You can define a range of keysyms in one shot by providing a I<string>
1143with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1144should be a character not used by the strings.
1145
1146Its usage can be demonstrated by an example:
1147
1148 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1149
1150The above line is equivalent to the following three lines:
1151
1152 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1153 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1154 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1155
1156If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1157is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1158example the following means "change the current locale to C<zh_CN.GBK>
1159when Control-Meta-c is being pressed":
1160
1161 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1162
1163If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1164is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1165manpage. For example, the F<selection> extension (activated via
1166C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1167
1168 URxvt.keysym.M-C-c: perl:selection:rot13
1169
1170Due the the large number of modifier combinations, a defined key mapping
1171will match if at I<at least> the specified identifiers are being set, and
1172no other key mappings with those and more bits are being defined. That
1173means that defining a key map for C<a> will automatically provide
1174definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1175mappings themselves.
1176
1177Unfortunately, this will override built-in key mappings. For example
1178if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1179C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1180user-defined keymap using the C<builtin:> replacement:
1181
1182 URxvt.keysym.Insert: <my insert key sequence>
1183 URxvt.keysym.S-Insert: builtin:
1184
1185The first line defines a mapping for C<Insert> and I<any> combination
1186of modifiers. The second line re-establishes the default mapping for
1187C<Shift-Insert>.
1188
1189The following example will map Control-Meta-1 and Control-Meta-2 to
1190the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1191font-switching at runtime:
1192
1193 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1194 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1195
1196Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1197info):
1198
1199 URxvt.keysym.M-C-3: command:\033[8;25;80t

1206Comma-separated list(s) of perl extension scripts (default: C<default>) to
1207use in this terminal instance; option B<-pe>.
1208
1209Extension names can be prefixed with a C<-> sign to prohibit using
1210them. This can be useful to selectively disable some extensions loaded
1211by default, or specified via the C<perl-ext-common> resource. For
1212example, C<default,-selection> will use all the default extension except
1213C<selection>.
1214
1215Extension names can also be followed by an argument in angle brackets
1216(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1217searchable scrollback to Alt/Meta-s). Mentioning the same extension
1218multiple times with different arguments will pass multiple arguments to
1219the extension.
1220
1221Each extension is looked up in the library directories, loaded if
1222necessary, and bound to the current terminal instance.
1223
1224If both of these resources are the empty string, then the perl
1225interpreter will not be initialized. The idea behind two options is that
1226B<perl-ext-common> will be used for extensions that should be available to

1352
1353=head1 ISO 14755 SUPPORT
1354
1355ISO 14755 is a standard for entering and viewing unicode characters
1356and character codes using the keyboard. It consists of 4 parts. The
1357first part is available if rxvt-unicode has been compiled with
1358C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1359with C<--enable-iso14755>.
1360
1361=over 4
1362
1363=item * 5.1: Basic method
1364
1365This allows you to enter unicode characters using their hexcode.
1366
1367Start by pressing and holding both C<Control> and C<Shift>, then enter
1368hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1369commit the character as if it were typed directly. While holding down
1370C<Control> and C<Shift> you can also enter multiple characters by pressing
1371C<Space>, which will commit the current character and lets you start a new
1372one.
1373
1374As an example of use, imagine a business card with a japanese e-mail
1375address, which you cannot type. Fortunately, the card has the e-mail
1376address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1377by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1378followed by releasing the modifier keys.
1379
1380=item * 5.2: Keyboard symbols entry method
1381
1382This mode lets you input characters representing the keycap symbols of
1383your keyboard, if representable in the current locale encoding.
1384
1385Start by pressing C<Control> and C<Shift> together, then releasing
1386them. The next special key (cursor keys, home etc.) you enter will not
1387invoke its usual function but instead will insert the corresponding
1388keycap symbol. The symbol will only be entered when the key has been
1389released, otherwise pressing e.g. C<Shift> would enter the symbol for
1390C<ISO Level 2 Switch>, although your intention might have been to enter a
1391reverse tab (Shift-Tab).
1392
1393=item * 5.3: Screen-selection entry method
1394
1395While this is implemented already (it's basically the selection
1396mechanism), it could be extended by displaying a unicode character map.
1397
1398=item * 5.4: Feedback method for identifying displayed characters for later input
1399
1400This method lets you display the unicode character code associated with
1401characters already displayed.
1402
1403You enter this mode by holding down C<Control> and C<Shift> together, then
1404pressing and holding the left mouse button and moving around. The unicode
1405hex code(s) (it might be a combining character) of the character under the
1406pointer is displayed until you release C<Control> and C<Shift>.
1407
1408In addition to the hex codes it will display the font used to draw this
1409character - due to implementation reasons, characters combined with
1410combining characters, line drawing characters and unknown characters will
1411always be drawn using the built-in support font.

1462consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
146316>), followed by 8 additional shades of gray (with indices 80 to 87).
1464
1465Together, all those colours implement the 88 colour xterm colours. Only

1483=head2 ALPHA CHANNEL SUPPORT
1484
1485If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1486their act together, rxvt-unicode will do it's own alpha channel management:
1487
1488You can prefix any color with an opaquenes percentage enclosed in
1489brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1490(0-100) that specifies the opacity of the color, where C<0> is completely
1491transparent and C<100> is completely opaque. For example, C<[50]red> is a
1492half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1493is the recommended format to specify transparency values, and works with
1494all ways to specify a colour.
1495
1496For complete control, rxvt-unicode also supports
1497C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1498specifications, where the additional C<aaaa> component specifies opacity
1499(alpha) values. The minimum value of C<0000> is completely transparent,
1500while C<ffff> is completely opaque). The two example colours from
1501earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1502C<rgba:0000/ff00/0000/f332>.
1503
1504You probably need to specify B<"-depth 32">, too, to force a visual with
1505alpha channels, and have the luck that your X-server uses ARGB pixel
1506layout, as X is far from just supporting ARGB visuals out of the box, and
1507rxvt-unicode just fudges around.
1508
1509For example, the following selects an almost completely transparent black
1510background, and an almost opaque pink foreground:
1511
1512 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1513
1514When not using a background image, then the interpretation of the
1515alpha channel is up to your compositing manager (most interpret it as
1516transparency of course).
1517
1518When using a background pixmap or pseudo-transparency, then the background
1519colour will always behave as if it were completely transparent (so the
1520background image shows instead), regardless of how it was specified, while
1521other colours will either be transparent as specified (the background
1522image will show through) on servers supporting the RENDER extension, or
1523fully opaque on servers not supporting the RENDER EXTENSION.
1524
1525Please note that due to bugs in Xft, specifying alpha values might result
1526in garbage being displayed when the X-server does not support the RENDER
1527extension.
