3     rxvt-unicode (ouR XVT, unicode) - (a VT102 emulator for the X window system)
4    
5     =head1 SYNOPSIS
6    
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:

176 root 1.22 Select the fonts to be used. This is a comma separated list of font names
177     that are used in turn when trying to display Unicode characters. The
178     first font defines the cell size for characters; other fonts might be
179 root 1.34 smaller, but not (in general) larger. A (hopefully) reasonable default
180     font list is always appended to it. See resource B<font> for more details.
181    
182     In short, to specify an X11 core font, just specify it's name or prefix it
183     with C<x:>. To specify an XFT-font, you need to prefix it with C<xft:>,

408     which enables applications to easily embed a terminal.
409    
410     Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
411     shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
412     quite a bit, so don't expect it to keep some specific state. It's best to
413     create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
414    
415 root 1.57 The window will not be destroyed when @@RXVT_NAME@@ exits.
416    
417 root 1.56 It might be useful to know that @@RXVT_NAME@@ will not close file
418     descriptors passed to it (except for stdin/out/err, of course), so you
419     can use file descriptors to communicate with the programs within the
420     terminal. This works regardless of wether the C<-embed> option was used or
421     not.
422 root 1.1
423 root 1.59 Here is a short Gtk2-perl snippet that illustrates how this option can be
424     used (a longer example is in F<doc/embed>):
425    
426 root 1.61 my $rxvt = new Gtk2::Socket;
427     $rxvt->signal_connect_after (realize => sub {
428     my $xid = $_[0]->window->get_xid;

430     });
431 root 1.59
432     =item B<-pty-fd> I<fileno>
433    
434     Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
435     pair but instead use the given filehandle as the tty master. This is
436     useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
437     without having to run a program within it.
438    
439     If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
440     entries and will not tinker with pty/tty permissions - you have to do that
441     yourself if you want that.
442    
443     Here is a example in perl that illustrates how this option can be used (a
444     longer example is in F<doc/pty-fd>):
445    
446     use IO::Pty;
447     use Fcntl;
448    
449     my $pty = new IO::Pty;
450     fcntl $pty, F_SETFD, 0; # clear close-on-exec

467     Xresources reader (B<~/.Xdefaults>). For the first method (ie.
468 root 1.2 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
469 root 1.53 resources using X11 tools like B<xrdb>. Many distribution do also load
470     settings from the B<~/.Xresources> file when X starts. @@RXVT_NAME@@
471     will consult the following files/resources in order, with later settings
472     overwriting earlier ones:
473    
474     1. system-wide app-defaults file, either locale-dependent OR global
475     2. app-defaults file in $XAPPLRESDIR
476     3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
477     4. SCREEN_RESOURCES for the current screen
478     5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
479 root 1.1
480 root 1.2 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
481     lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
482 root 1.1 set in XAPPLOADDIR/URxvt (compile-time defined: usually
483     B</usr/lib/X11/app-defaults/URxvt>) and resources set in
484     B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
485 root 1.2 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
486 root 1.1 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
487 root 1.2 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
488 root 1.1 easily configured, while the class name B<URxvt> allows resources
489 root 1.2 unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
490     shared between different B<@@RXVT_NAME@@> configurations. If no
491 root 1.1 resources are specified, suitable defaults will be used. Command-line
492     arguments can be used to override resource settings. The following
493     resources are allowed:

639 root 1.1 names that are used in turn when trying to display Unicode characters.
640     The first font defines the cell size for characters; other fonts might
641     be smaller, but not larger. A reasonable default font list is always
642     appended to it. option B<-fn>.
643    
644 root 1.22 Each font can either be a standard X11 core font (XLFD) name, with
645 root 1.43 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
646 root 1.22
647     In addition, each font can be prefixed with additional hints and
648     specifications enclosed in square brackets (C<[]>). The only available
649     hint currently is C<codeset=codeset-name>, and this is only used for Xft
650     fonts.

661     the iso8859-1 version of the second font), which is the base font (because
662     it is named first) and thus defines the character cell grid to be 9 pixels
663     wide and 15 pixels high.
664    
665 root 1.34 The second font is just used to add additional unicode characters not in
666 root 1.22 the base font, likewise the third, which is unfortunately non-bold, but
667     the bold version of the font does contain less characters, so this is a
668     useful supplement.
669    
670     The third font is an Xft font with aliasing turned off, and the characters
671     are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
672     contains other characters, but we are not interested in them.

688     it possible to substitute completely different font styles for bold and
689     italic.
690    
691     If unset (the default), a suitable font list will be synthesized by
692     "morphing" the normal text font list into the desired shape. If that is

926     Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
927     echo arbitrary strings like the icon name or the locale. This could be
928 root 1.30 abused if somebody gets 8-bit-clean access to your display, whether
929 root 1.73 through a mail client displaying mail bodies unfiltered or through

931     default. (Note that many other terminals, including xterm, have these
932     sequences enabled by default, which doesn't make it safer, though).
933    
934     You can enable them by setting this boolean resource or specifying
935     B<-insecure> as an option. At the moment, this enables display-answer,

971 root 1.43 Compile I<frills>: Associate I<string> with keysym I<sym>. The
972     intervening resource name B<keysym.> cannot be omitted.
973    
974     The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
975     any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
976     B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
977     and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
978     B<2>, B<3>, B<4>, B<5>.
979    
980     The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
981     whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
982 root 1.48 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
983 root 1.43 current application keymap mode state.
984    
985     The spellings of I<key> can be obtained by using B<xev>(1) command or
986     searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
987     omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
988     keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
989     performed in an exact manner; however, the closest match is assured.
990    
991     I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
992     C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
993     C<\000>: octal number) or verbatim control characters (C<^?>: delete,
994     C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
995     can start or end with whitespace.
996    
997 root 1.48 Please note that you need to double the C<\> when using
998     C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
999     use C<\033> instead of C<\e> (and so on), which will work with both Xt and
1000     @@RXVT_NAME@@'s own processing).
1001    
1002 root 1.43 You can define a range of keysyms in one shot by providing a I<string>
1003     with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
1004     should be a character not used by the strings.
1005    
1006     Its usage can be demonstrated by an example:
1007    
1008 root 1.48 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1009 root 1.43
1010     The above line is equivalent to the following three lines:
1011    
1012 root 1.48 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1013     URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1014     URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1015    
1016     If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1017     is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1018     example the following means "change the current locale to C<zh_CN.GBK>
1019     when Control-Meta-c is being pressed":
1020    
1021     URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1022    
1023 root 1.63 Due the the large number of modifier combinations, a defined key mapping
1024     will match if at I<at least> the specified identifiers are being set, and
1025     no other key mappings with those and more bits are being defined. That
1026     means that defining a key map for C<a> will automatically provide
1027     definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1028     mappings themselves.
1029    
1030     Unfortunately, this will override built-in key mappings. For example
1031     if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1032     C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1033     user-defined keymap using the C<builtin:> replacement:
1034    
1035     URxvt.keysym.Insert: <my insert key sequence>
1036     URxvt.keysym.S-Insert: builtin:
1037    
1038     The first line defines a mapping for C<Insert> and I<any> combination
1039     of modifiers. The second line re-establishes the default mapping for
1040     C<Shift-Insert>.
1041    
1042 root 1.48 The following example will map Control-Meta-1 and Control-Meta-2 to
1043     the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1044     font-switching at runtime:
1045    
1046     URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1047     URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1048    
1049     Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1050     info):
1051    
1052     URxvt.keysym.M-C-3: command:\033[8;25;80t

1061 root 1.2 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1062 root 1.1 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1063     arrows and its behaviour mimics that of I<xterm>

1071     To temporarily override mouse reporting, for either the scrollbar or

1073     (Alt) key while performing the desired mouse action.
1074    
1075     If mouse reporting mode is active, the normal scrollbar actions are
1076     disabled -- on the assumption that we are using a fullscreen
1077 root 1.53 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1078     (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the

1134 root 1.12
1135     This allows you to enter unicode characters using their hexcode.
1136 root 1.2
1137 root 1.12 Start by pressing and holding both C<Control> and C<Shift>, then enter
1138     hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1139     commit the character as if it were typed directly. While holding down
1140     C<Control> and C<Shift> you can also enter multiple characters by pressing
1141     C<Space>, which will commit the current character and lets you start a new
1142     one.
1143    
1144     As an example of use, imagine a business card with a japanese e-mail
1145     address, which you cannot type. Fortunately, the card has the e-mail
1146     address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1147     by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1148     followed by releasing the modifier keys.

1151 root 1.12

1154    
1155     Start by pressing C<Control> and C<Shift> together, then releasing
1156     them. The next special key (cursor keys, home etc.) you enter will not
1157     invoke it's usual function but instead will insert the corresponding
1158     keycap symbol. The symbol will only be entered when the key has been
1159     released, otherwise pressing e.g. C<Shift> would enter the symbol for
1160 root 1.30 C<ISO Level 2 Switch>, although your intention might have been to enter a
1161 root 1.12 reverse tab (Shift-Tab).

1169 root 1.12
1170     This method lets you display the unicode character code associated with
1171     characters already displayed.
1172    
1173     You enter this mode by holding down C<Control> and C<Shift> together, then
1174     pressing and holding the left mouse button and moving around. The unicode
1175     hex code(s) (it might be a combining character) of the character under the
1176     pointer is displayed until you release C<Control> and C<Shift>.
1177    
1178 root 1.22 In addition to the hex codes it will display the font used to draw this
1179     character - due to implementation reasons, characters combined with
