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:>,

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

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

427     $rxvt->signal_connect_after (realize => sub {

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>):

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

523     names used are listed in the B<COLORS AND GRAPHICS> section.
524    
525 root 1.22 Colours higher than 15 cannot be set using resources (yet), but can be
526     changed using an escape command (see @@RXVT_NAME@@(7)).

622     centre (percent). A scale of 0 displays the image with tiling. A scale
623     of 1 displays the image without any scaling. A scale of 2 to 9
624     specifies an integer number of images in that direction. No image will
625     be magnified beyond 10 times its original size. The maximum permitted

632     reference documentation for details on the syntax for the menuBar.
633    
634     =item B<path:> I<path>
635    
636     Specify the colon-delimited search path for finding files (XPM and
637     menus), in addition to the paths specified by the B<RXVTPATH> and
638     B<PATH> environment variables.
639    
640 root 1.22 =item B<font:> I<fontlist>
641 root 1.1
642 root 1.22 Select the fonts to be used. This is a comma separated list of font
643 root 1.1 names that are used in turn when trying to display Unicode characters.
644     The first font defines the cell size for characters; other fonts might
645     be smaller, but not larger. A reasonable default font list is always
646 root 1.77 appended to it; option B<-fn>.
647 root 1.1
648 root 1.22 Each font can either be a standard X11 core font (XLFD) name, with
649 root 1.43 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
650 root 1.22
651     In addition, each font can be prefixed with additional hints and
652     specifications enclosed in square brackets (C<[]>). The only available
653     hint currently is C<codeset=codeset-name>, and this is only used for Xft
654     fonts.
655    
656     For example, this font resource
657 root 1.1
658 root 1.22 URxvt*font: 9x15bold,\
659     -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
660     -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
661     [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
662     xft:Code2000:antialias=false
663    
664     specifies five fonts to be used. The first one is C<9x15bold> (actually
665     the iso8859-1 version of the second font), which is the base font (because
666     it is named first) and thus defines the character cell grid to be 9 pixels
667     wide and 15 pixels high.
668    
669 root 1.34 The second font is just used to add additional unicode characters not in
670 root 1.22 the base font, likewise the third, which is unfortunately non-bold, but
671     the bold version of the font does contain less characters, so this is a
672     useful supplement.
673    
674     The third font is an Xft font with aliasing turned off, and the characters
675     are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
676     contains other characters, but we are not interested in them.
677    
678     The last font is a useful catch-all font that supplies most of the
679     remaining unicode characters.
680    
681     =item B<boldFont:> I<fontlist>
682    
683     =item B<italicFont:> I<fontlist>
684    
685     =item B<boldItalicFont:> I<fontlist>
686    
687     The font list to use for displaying B<bold>, I<italic> or B<< I<bold
688     italic> >> characters, respectively.
689    
690     If specified and non-empty, then the syntax is the same as for the
691     B<font>-resource, and the given font list will be used as is, which makes
692     it possible to substitute completely different font styles for bold and
693     italic.
694    
695     If unset (the default), a suitable font list will be synthesized by
696     "morphing" the normal text font list into the desired shape. If that is
697     not possible, replacement fonts of the desired shape will be tried.
698    
699     If set, but empty, then this specific style is disabled and the normal
700     text font will being used for the given style.
701 root 1.1
702 root 1.76 =item B<intensityStyles:> I<boolean>
703    
704     When font styles are not enabled, or this option is enabled (B<True>,
705     option B<-is>, the default), bold and italic font styles imply high
706     intensity foreground/backround colours. Disabling this option (B<False>,
707     option B<+is>) disables this behaviour, the high intensity colours are not
708     reachable.
709    
710 root 1.1 =item B<selectstyle:> I<mode>
711    
712     Set mouse selection style to B<old> which is 2.20, B<oldword> which is
713     xterm style with 2.20 old word selection, or anything else which gives
714     xterm style selection.

716     =item B<scrollstyle:> I<mode>
717    
718 root 1.3 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is

754    
755     =item B<print-pipe:> I<string>
756    
757     Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
758     B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
759     B<Shift-Print> to include the scrollback as well.
760    
761 root 1.65 The string will be interpreted as if typed into the shell as-is.
762    
763 root 1.66 Example:
764

931     echo arbitrary strings like the icon name or the locale. This could be
932 root 1.30 abused if somebody gets 8-bit-clean access to your display, whether
933 root 1.73 through a mail client displaying mail bodies unfiltered or through

935     default. (Note that many other terminals, including xterm, have these
936     sequences enabled by default, which doesn't make it safer, though).
937    
938     You can enable them by setting this boolean resource or specifying
939     B<-insecure> as an option. At the moment, this enables display-answer,

975 root 1.43 Compile I<frills>: Associate I<string> with keysym I<sym>. The
976     intervening resource name B<keysym.> cannot be omitted.
977    
978     The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
979     any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
980     B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
981     and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
982     B<2>, B<3>, B<4>, B<5>.
983    
984     The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
985     whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
986 root 1.48 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
987 root 1.43 current application keymap mode state.
988    
989     The spellings of I<key> can be obtained by using B<xev>(1) command or
990     searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
991     omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
992     keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
993     performed in an exact manner; however, the closest match is assured.
994    
995     I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
996     C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
997     C<\000>: octal number) or verbatim control characters (C<^?>: delete,
998     C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
999     can start or end with whitespace.
1000    
1001 root 1.48 Please note that you need to double the C<\> when using
1002     C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
1003     use C<\033> instead of C<\e> (and so on), which will work with both Xt and
1004     @@RXVT_NAME@@'s own processing).
1005    
1006 root 1.43 You can define a range of keysyms in one shot by providing a I<string>
1007     with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
1008     should be a character not used by the strings.
1009    
1010     Its usage can be demonstrated by an example:
1011    
1012 root 1.48 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1013 root 1.43
1014     The above line is equivalent to the following three lines:
1015    
1016 root 1.48 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1017     URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1018     URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1019    
1020     If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1021     is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1022     example the following means "change the current locale to C<zh_CN.GBK>
1023     when Control-Meta-c is being pressed":
1024    
1025     URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1026    
1027 root 1.80 If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1028     is passed to the C<on_keyboard_command> perl handler. See the rxvtperl(3)
1029     manpage. For example, the F<selection> extension (activated via
1030     C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1031    
1032     URxvt.keysym.M-C-c: perl:selection:rot13
1033    
1034 root 1.63 Due the the large number of modifier combinations, a defined key mapping
1035     will match if at I<at least> the specified identifiers are being set, and
1036     no other key mappings with those and more bits are being defined. That
1037     means that defining a key map for C<a> will automatically provide
1038     definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1039     mappings themselves.
1040    
1041     Unfortunately, this will override built-in key mappings. For example
1042     if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1043     C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1044     user-defined keymap using the C<builtin:> replacement:
1045    
1046     URxvt.keysym.Insert: <my insert key sequence>
1047     URxvt.keysym.S-Insert: builtin:
1048    
1049     The first line defines a mapping for C<Insert> and I<any> combination
1050     of modifiers. The second line re-establishes the default mapping for
1051     C<Shift-Insert>.
1052    
1053 root 1.48 The following example will map Control-Meta-1 and Control-Meta-2 to
1054     the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1055     font-switching at runtime:
1056    
1057     URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1058     URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1059    
1060     Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1061     info):

1167 root 1.2
1168 root 1.12 Start by pressing and holding both C<Control> and C<Shift>, then enter
1169     hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1170     commit the character as if it were typed directly. While holding down
1171     C<Control> and C<Shift> you can also enter multiple characters by pressing
1172     C<Space>, which will commit the current character and lets you start a new
1173     one.
1174    
1175     As an example of use, imagine a business card with a japanese e-mail
1176     address, which you cannot type. Fortunately, the card has the e-mail
1177     address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1178     by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1179     followed by releasing the modifier keys.

1182 root 1.12
1183     This mode lets you input characters representing the keycap symbols of

1185    
1186     Start by pressing C<Control> and C<Shift> together, then releasing
1187     them. The next special key (cursor keys, home etc.) you enter will not
1188     invoke it's usual function but instead will insert the corresponding
1189     keycap symbol. The symbol will only be entered when the key has been
1190     released, otherwise pressing e.g. C<Shift> would enter the symbol for
1191 root 1.30 C<ISO Level 2 Switch>, although your intention might have been to enter a

1203    
1204     You enter this mode by holding down C<Control> and C<Shift> together, then
1205     pressing and holding the left mouse button and moving around. The unicode
1206     hex code(s) (it might be a combining character) of the character under the
1207     pointer is displayed until you release C<Control> and C<Shift>.
1208
