3     rxvt-unicode (ouR XVT, unicode) - (a VT102 emulator for the X window system)

5     =head1 SYNOPSIS

7 root 1.2 B<@@RXVT_NAME@@> [options] [-e command [ args ]]
8 root 1.1
9     =head1 DESCRIPTION
10    
11 root 1.3 B<rxvt-unicode>, version B<@@RXVT_VERSION@@>, is a colour vt102 terminal
12 root 1.1 emulator intended as an I<xterm>(1) replacement for users who do not
13     require features such as Tektronix 4014 emulation and toolkit-style
14     configurability. As a result, B<rxvt-unicode> uses much less swap space --
15     a significant advantage on a machine serving many X sessions.
16    
17 root 1.30 =head1 FREQUENTLY ASKED QUESTIONS
18    
19 root 1.53 See @@RXVT_NAME@@(7) (try C<man 7 @@RXVT_NAME@@>) for a list of
20     frequently asked questions and answer to them and some common
21     problems. That document is also accessible on the World-Wide-Web at
22     L<http://cvs.schmorp.de/browse/*checkout*/rxvt-unicode/doc/rxvt.7.html>.
23 root 1.30
24 root 1.5 =head1 RXVT-UNICODE VS. RXVT
25    
26     Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
27     internally. That means it can store and display most scripts in the
28     world. Being a terminal emulator, however, some things are very difficult,
29     especially cursive scripts such as arabic, vertically written scripts
30     like mongolian or scripts requiring extremely complex combining rules,
31     like tibetan or devenagari. Don't expect pretty output when using these
32     scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
33     fine, though. A somewhat difficult case are left-to-right scripts, such
34     as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
35     belong into the application, not the terminal emulator (too many things --
36 root 1.30 such as cursor-movement while editing -- break otherwise), but that might
37 root 1.12 change.
38 root 1.5
39 root 1.12 If you are looking for a terminal that supports more exotic scripts, let
40     me recommend C<mlterm>, which is a very userfriendly, lean and clean
41     terminal emulator. In fact, the reason rxvt-unicode was born was solely
42     because the author couldn't get C<mlterm> to use one font for latin1 and
43     another for japanese.
44    
45     Therefore another design rationale was the use of multiple fonts to
46     display characters: The idea of a single unicode font which many other
47     programs force onto it's users never made sense to me: You should be able
48     to choose any font for any script freely.
49 root 1.5
50     Apart from that, rxvt-unicode is also much better internationalised than
51     it's predecessor, supports things such as XFT and ISO 14755 that are handy
52     in i18n-environments, is faster, and has a lot less bugs than the original
53     rxvt. This all in addition to dozens of other small improvements.
54    
55     It is still faithfully following the original rxvt idea of being lean
56     and nice on resources: for example, you can still configure rxvt-unicode
57     without most of it's features to get a lean binary. It also comes with
58     a client/daemon pair that lets you open any number of terminal windows
59     from within a single process, which makes startup time very fast and
60     drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
61     @@RXVT_NAME@@c(1) (client).
62    
63     It also makes technical information about escape sequences (which have
64     been extended) easier accessible: see @@RXVT_NAME@@(7) for technical
65 root 1.30 reference documentation (escape sequences etc.).
66 root 1.2
67 root 1.1 =head1 OPTIONS
68    
69 root 1.2 The B<@@RXVT_NAME@@> options (mostly a subset of I<xterm>'s) are listed
70 root 1.1 below. In keeping with the smaller-is-better philosophy, options may be
71     eliminated or default values chosen at compile-time, so options and
72     defaults listed may not accurately reflect the version installed on
73 root 1.3 your system. `@@RXVT_NAME@@ -h' gives a list of major compile-time options on
74 root 1.1 the I<Options> line. Option descriptions may be prefixed with which
75     compile option each is dependent upon. e.g. `Compile I<XIM>:' requires
76 root 1.3 I<XIM> on the I<Options> line. Note: `@@RXVT_NAME@@ -help' gives a list of all
77 root 1.1 command-line options compiled into your version.
78    
79 root 1.2 Note that B<@@RXVT_NAME@@> permits the resource name to be used as a
80 root 1.1 long-option (--/++ option) so the potential command-line options are
81 root 1.3 far greater than those listed. For example: `@@RXVT_NAME@@ --loginShell --color1
82 root 1.1 Orange'.
83    
84     The following options are available:

142     Compile I<XPM>: Specify XPM file for the background and also optionally
143 root 1.43 specify its scaling with a geometry string. Note you may need to
144     add quotes to avoid special shell interpretation of the C<;> in the
145 root 1.1 command-line; resource B<backgroundPixmap>.

163    
164 root 1.22 =item B<-fn> I<fontlist>
165 root 1.1
166 root 1.22 Select the fonts to be used. This is a comma separated list of font names
167     that are used in turn when trying to display Unicode characters. The
168     first font defines the cell size for characters; other fonts might be
169 root 1.34 smaller, but not (in general) larger. A (hopefully) reasonable default
170     font list is always appended to it. See resource B<font> for more details.
171    
172     In short, to specify an X11 core font, just specify it's name or prefix it
173     with C<x:>. To specify an XFT-font, you need to prefix it with C<xft:>,

377 root 1.59 =item B<-embed> I<windowid>
378 root 1.1
379 root 1.56 Tells @@RXVT_NAME@@ to embed it's windows into an already-existing window,
380     which enables applications to easily embed a terminal.
381    
382     Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
383     shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
384     quite a bit, so don't expect it to keep some specific state. It's best to
385     create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
386    
387 root 1.57 The window will not be destroyed when @@RXVT_NAME@@ exits.
388    
389 root 1.56 It might be useful to know that @@RXVT_NAME@@ will not close file
390     descriptors passed to it (except for stdin/out/err, of course), so you
391     can use file descriptors to communicate with the programs within the
392     terminal. This works regardless of wether the C<-embed> option was used or
393     not.
394 root 1.1
395 root 1.59 Here is a short Gtk2-perl snippet that illustrates how this option can be
396     used (a longer example is in F<doc/embed>):
397    
398 root 1.61 my $rxvt = new Gtk2::Socket;
399     $rxvt->signal_connect_after (realize => sub {
400     my $xid = $_[0]->window->get_xid;
401     system "@@RXVT_NAME@@ -embed $xid &";
402     });
403 root 1.59
404     =item B<-pty-fd> I<fileno>
405    
406     Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
407     pair but instead use the given filehandle as the tty master. This is
408     useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
409     without having to run a program within it.
410    
411     If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
412     entries and will not tinker with pty/tty permissions - you have to do that
413     yourself if you want that.
414    
415     Here is a example in perl that illustrates how this option can be used (a
416     longer example is in F<doc/pty-fd>):
417    
418     use IO::Pty;
419     use Fcntl;
420    
421     my $pty = new IO::Pty;
422     fcntl $pty, F_SETFD, 0; # clear close-on-exec
423     system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
424 root 1.60 close $pty;
425 root 1.59
426     # now communicate with rxvt
427     my $slave = $pty->slave;
428     while (<$slave>) { print $slave "got <$_>\n" }
429    
430 root 1.1 =back
431    
432     =head1 RESOURCES (available also as long-options)
433    
434 root 1.2 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
435 root 1.1 options) compiled into your version.
436    
437 root 1.2 There are two different methods that @@RXVT_NAME@@ can use to get the
438 root 1.1 Xresource data: using the X libraries (Xrm*-functions) or internal
439     Xresources reader (B<~/.Xdefaults>). For the first method (ie.
440 root 1.2 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
441 root 1.53 resources using X11 tools like B<xrdb>. Many distribution do also load
442     settings from the B<~/.Xresources> file when X starts. @@RXVT_NAME@@
443     will consult the following files/resources in order, with later settings
444     overwriting earlier ones:
445    
446     1. system-wide app-defaults file, either locale-dependent OR global
447     2. app-defaults file in $XAPPLRESDIR
448     3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
449     4. SCREEN_RESOURCES for the current screen
450     5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
451 root 1.1
452 root 1.2 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
453     lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
454 root 1.1 set in XAPPLOADDIR/URxvt (compile-time defined: usually
455     B</usr/lib/X11/app-defaults/URxvt>) and resources set in
456     B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
457 root 1.2 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
458 root 1.1 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
459 root 1.2 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
460 root 1.1 easily configured, while the class name B<URxvt> allows resources

605 root 1.1 names that are used in turn when trying to display Unicode characters.
606     The first font defines the cell size for characters; other fonts might
607     be smaller, but not larger. A reasonable default font list is always
608     appended to it. option B<-fn>.
609    
610 root 1.22 Each font can either be a standard X11 core font (XLFD) name, with
611 root 1.43 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
612 root 1.22
613     In addition, each font can be prefixed with additional hints and
614     specifications enclosed in square brackets (C<[]>). The only available

627     the iso8859-1 version of the second font), which is the base font (because
628     it is named first) and thus defines the character cell grid to be 9 pixels
629     wide and 15 pixels high.
630

632 root 1.22 the base font, likewise the third, which is unfortunately non-bold, but
633     the bold version of the font does contain less characters, so this is a
634     useful supplement.

636     The third font is an Xft font with aliasing turned off, and the characters
637     are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
638     contains other characters, but we are not interested in them.

919    
920 root 1.43 Compile I<frills>: Associate I<string> with keysym I<sym>. The
921     intervening resource name B<keysym.> cannot be omitted.
922    
923     The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
924     any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
925     B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
926     and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
927     B<2>, B<3>, B<4>, B<5>.
928    
929     The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
930     whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
931 root 1.48 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
932 root 1.43 current application keymap mode state.
933    
934     The spellings of I<key> can be obtained by using B<xev>(1) command or
935     searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
936     omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
937     keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
938     performed in an exact manner; however, the closest match is assured.
939    
940     I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
941     C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
942     C<\000>: octal number) or verbatim control characters (C<^?>: delete,
943     C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
944     can start or end with whitespace.
945    
946 root 1.48 Please note that you need to double the C<\> when using
947     C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
948     use C<\033> instead of C<\e> (and so on), which will work with both Xt and
949     @@RXVT_NAME@@'s own processing).
950    
951 root 1.43 You can define a range of keysyms in one shot by providing a I<string>
952     with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
953     should be a character not used by the strings.
954    
955     Its usage can be demonstrated by an example:
956    
957 root 1.48 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
958 root 1.43
959     The above line is equivalent to the following three lines:
960    
961 root 1.48 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
962     URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
963     URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
964    
965     If I<string> takes the form of C<command:STRING>, the specified B<STRING>
966     is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
967     example the following means "change the current locale to C<zh_CN.GBK>
968     when Control-Meta-c is being pressed":
969    
970     URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
971    
972 root 1.63 Due the the large number of modifier combinations, a defined key mapping
973     will match if at I<at least> the specified identifiers are being set, and
974     no other key mappings with those and more bits are being defined. That
975     means that defining a key map for C<a> will automatically provide
976     definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
977     mappings themselves.
978    
979     Unfortunately, this will override built-in key mappings. For example
980     if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
981     C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
982     user-defined keymap using the C<builtin:> replacement:
983    
984     URxvt.keysym.Insert: <my insert key sequence>
985     URxvt.keysym.S-Insert: builtin:
986    
987     The first line defines a mapping for C<Insert> and I<any> combination
988     of modifiers. The second line re-establishes the default mapping for
989     C<Shift-Insert>.
990    
991 root 1.48 The following example will map Control-Meta-1 and Control-Meta-2 to
992     the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
993     font-switching at runtime:
994    
995     URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
996     URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
997    
998     Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
999     info):
1000    
1001     URxvt.keysym.M-C-3: command:\033[8;25;80t

1009 root 1.1 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1010 root 1.2 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1011 root 1.1 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1012     arrows and its behaviour mimics that of I<xterm>
1013    
1014     Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.

1019    
1020     To temporarily override mouse reporting, for either the scrollbar or
1021     the normal text selection/insertion, hold either the Shift or the Meta
1022     (Alt) key while performing the desired mouse action.
1023    
1024     If mouse reporting mode is active, the normal scrollbar actions are
1025     disabled -- on the assumption that we are using a fullscreen
1026 root 1.53 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1027     (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1028     up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),

1080 root 1.48 =item * 5.1: Basic method
1081 root 1.12
1082     This allows you to enter unicode characters using their hexcode.
1083 root 1.2
1084 root 1.12 Start by pressing and holding both C<Control> and C<Shift>, then enter
1085     hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1086     commit the character as if it were typed directly. While holding down
1087     C<Control> and C<Shift> you can also enter multiple characters by pressing
1088     C<Space>, which will commit the current character and lets you start a new
1089     one.
1090    
1091     As an example of use, imagine a business card with a japanese e-mail
1092     address, which you cannot type. Fortunately, the card has the e-mail
1093     address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1094     by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1095     followed by releasing the modifier keys.
1096    
1097 root 1.48 =item * 5.2: Keyboard symbols entry method
1098 root 1.12
1099     This mode lets you input characters representing the keycap symbols of
1100     your keyboard, if representable in the current locale encoding.
1101    
1102     Start by pressing C<Control> and C<Shift> together, then releasing
1103     them. The next special key (cursor keys, home etc.) you enter will not
1104     invoke it's usual function but instead will insert the corresponding
1105     keycap symbol. The symbol will only be entered when the key has been
1106     released, otherwise pressing e.g. C<Shift> would enter the symbol for
1107 root 1.30 C<ISO Level 2 Switch>, although your intention might have been to enter a
1108 root 1.12 reverse tab (Shift-Tab).
1109    
1110 root 1.48 =item * 5.3: Screen-selection entry method
1111 root 1.12
1112     While this is implemented already (it's basically the selection
1113     mechanism), it could be extended by displaying a unicode character map.
1114    
1115 root 1.48 =item * 5.4: Feedback method for identifying displayed characters for later input
1116 root 1.12
1117     This method lets you display the unicode character code associated with
1118     characters already displayed.
1119    
1120     You enter this mode by holding down C<Control> and C<Shift> together, then
1121     pressing and holding the left mouse button and moving around. The unicode
1122     hex code(s) (it might be a combining character) of the character under the
1123     pointer is displayed until you release C<Control> and C<Shift>.
1124    
1125 root 1.22 In addition to the hex codes it will display the font used to draw this
1126     character - due to implementation reasons, characters combined with
1127     combining characters, line drawing characters and unknown characters will
1128     always be drawn using the built-in support font.
