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 root 1.121 L<http://cvs.schmorp.de/browse/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 root 1.115 fine, though. A somewhat difficult case are right-to-left scripts, such
34 root 1.5 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 root 1.118 me recommend C<mlterm>, which is a very user friendly, lean and clean
41 root 1.12 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 root 1.114 programs force onto its users never made sense to me: You should be able
48 root 1.12 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 root 1.114 its predecessor, supports things such as XFT and ISO 14755 that are handy
52 root 1.116 in i18n-environments, is faster, and has a lot bugs less than the original
53 root 1.5 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 root 1.114 without most of its features to get a lean binary. It also comes with
58 root 1.5 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 root 1.116 been extended) more 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'.

458 root 1.59 useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
459     without having to run a program within it.
460    
461     If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
462     entries and will not tinker with pty/tty permissions - you have to do that
463     yourself if you want that.

491    
492 root 1.2 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
493 root 1.1 options) compiled into your version.
494    
495 root 1.93 You can set and change the resources using X11 tools like B<xrdb>. Many
496     distribution do also load settings from the B<~/.Xresources> file when X
497     starts. @@RXVT_NAME@@ will consult the following files/resources in order,
498     with later settings overwriting earlier ones:
499 root 1.53
500     1. system-wide app-defaults file, either locale-dependent OR global
501     2. app-defaults file in $XAPPLRESDIR
502     3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
503     4. SCREEN_RESOURCES for the current screen
504     5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
505 root 1.1
506 root 1.93 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two class
507     names: B<Rxvt> and B<URxvt>. The class name B<Rxvt> allows resources
508     common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be easily
509     configured, while the class name B<URxvt> allows resources unique to
510     B<@@RXVT_NAME@@>, to be shared between different B<@@RXVT_NAME@@>
511     configurations. If no resources are specified, suitable defaults will
512     be used. Command-line arguments can be used to override resource
513     settings. The following resources are supported (you might want to
514     check the @@RXVT_NAME@@perl(3) manpage for additional settings by perl
515     extensions not documented here):

658 root 1.22 =item B<font:> I<fontlist>
659 root 1.1
660 root 1.96 Select the fonts to be used. This is a comma separated list of font names
661     that are checked in order when trying to find glyphs for characters. The
662     first font defines the cell size for characters; other fonts might be
663     smaller, but not (in general) larger. A (hopefully) reasonable default
664     font list is always appended to it; option B<-fn>.
665 root 1.1
666 root 1.22 Each font can either be a standard X11 core font (XLFD) name, with
667 root 1.43 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
668 root 1.22
669     In addition, each font can be prefixed with additional hints and
670     specifications enclosed in square brackets (C<[]>). The only available
671     hint currently is C<codeset=codeset-name>, and this is only used for Xft
672     fonts.
673    
674     For example, this font resource
675 root 1.1
676 root 1.97 URxvt.font: 9x15bold,\

680     xft:Code2000:antialias=false
681    
682     specifies five fonts to be used. The first one is C<9x15bold> (actually
683     the iso8859-1 version of the second font), which is the base font (because
684     it is named first) and thus defines the character cell grid to be 9 pixels
685     wide and 15 pixels high.
686    
687 root 1.34 The second font is just used to add additional unicode characters not in
688 root 1.22 the base font, likewise the third, which is unfortunately non-bold, but
689     the bold version of the font does contain less characters, so this is a
690     useful supplement.
691    
692     The third font is an Xft font with aliasing turned off, and the characters
693     are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
694     contains other characters, but we are not interested in them.
695    
696     The last font is a useful catch-all font that supplies most of the
697     remaining unicode characters.

709     B<font>-resource, and the given font list will be used as is, which makes
710     it possible to substitute completely different font styles for bold and
711     italic.
712    
713     If unset (the default), a suitable font list will be synthesized by
714     "morphing" the normal text font list into the desired shape. If that is
715     not possible, replacement fonts of the desired shape will be tried.
716    
717     If set, but empty, then this specific style is disabled and the normal

910     The string to send when the backspace key is pressed. If set to B<DEC>
911     or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
912     (code 8) - which can be reversed with the appropriate DEC private mode
913     escape sequence.
914    
915     =item B<deletekey:> I<string>
916    
917     The string to send when the delete key (not the keypad delete key) is
918     pressed. If unset it will send the sequence traditionally associated
919     with the B<Execute> key.
920    
921     =item B<cutchars:> I<string>
922    
923 root 1.105 The characters used as delimiters for double-click word selection

925 root 1.104
926     When the selection extension is in use (the default if compiled in, see
927     the @@RXVT_NAME@@perl(3) manpage), a suitable regex using these characters
928     will be created (if the resource exists, otherwise, no regex will be
929     created). In this mode, characters outside ISO-8859-1 can be used.
930    
931     When the selection extension is not used, only ISO-8859-1 characters can
932     be used. If not specified, the built-in default is used:

966 root 1.22 =item B<insecure:> I<boolean>
967 root 1.1
968     Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
969     echo arbitrary strings like the icon name or the locale. This could be
970 root 1.30 abused if somebody gets 8-bit-clean access to your display, whether
971 root 1.73 through a mail client displaying mail bodies unfiltered or through
972     write(1) or any other means. Therefore, these sequences are disabled by
973     default. (Note that many other terminals, including xterm, have these
974     sequences enabled by default, which doesn't make it safer, though).
975    
976     You can enable them by setting this boolean resource or specifying
977     B<-insecure> as an option. At the moment, this enables display-answer,
978 root 1.97 locale, findfont, icon label and window title requests.
979 root 1.1

1009    
1010 root 1.1 =item B<keysym.>I<sym>: I<string>
1011    
1012 root 1.43 Compile I<frills>: Associate I<string> with keysym I<sym>. The
1013     intervening resource name B<keysym.> cannot be omitted.
1014    
1015     The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1016     any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1017     B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1018     and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1019     B<2>, B<3>, B<4>, B<5>.
1020    
1021     The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1022     whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1023 root 1.48 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1024 root 1.43 current application keymap mode state.
1025    
1026     The spellings of I<key> can be obtained by using B<xev>(1) command or
1027     searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1028     omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1029     keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1030     performed in an exact manner; however, the closest match is assured.
1031    
1032     I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
1033     C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
1034     C<\000>: octal number) or verbatim control characters (C<^?>: delete,
1035     C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1036 root 1.120 can start or end with whitespace. B<This feature is deprecated and will
1037     be removed>.
1038 root 1.43
1039 root 1.93 Please note that you need to double the C<\> in resource files, as
1040 root 1.114 Xlib itself does its own de-escaping (you can use C<\033> instead of
1041 root 1.93 C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own
1042     processing).
1043 root 1.48
1044 root 1.43 You can define a range of keysyms in one shot by providing a I<string>
1045 root 1.118 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1046 root 1.43 should be a character not used by the strings.
1047    
1048     Its usage can be demonstrated by an example:
1049    
1050 root 1.48 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1051 root 1.43
1052     The above line is equivalent to the following three lines:
1053    
1054 root 1.48 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1055     URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1056     URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1057    
1058     If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1059     is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1060     example the following means "change the current locale to C<zh_CN.GBK>
1061     when Control-Meta-c is being pressed":
1062    
1063     URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1064    
1065 root 1.80 If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1066 root 1.81 is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1067 root 1.80 manpage. For example, the F<selection> extension (activated via
1068     C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1069    
1070     URxvt.keysym.M-C-c: perl:selection:rot13
1071    
1072 root 1.63 Due the the large number of modifier combinations, a defined key mapping
1073     will match if at I<at least> the specified identifiers are being set, and
1074     no other key mappings with those and more bits are being defined. That
1075     means that defining a key map for C<a> will automatically provide
1076     definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1077     mappings themselves.
1078    
1079     Unfortunately, this will override built-in key mappings. For example
1080     if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1081     C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1082     user-defined keymap using the C<builtin:> replacement:
1083    
1084     URxvt.keysym.Insert: <my insert key sequence>
1085     URxvt.keysym.S-Insert: builtin:
1086    
1087     The first line defines a mapping for C<Insert> and I<any> combination
1088     of modifiers. The second line re-establishes the default mapping for
1089     C<Shift-Insert>.
1090    
1091 root 1.48 The following example will map Control-Meta-1 and Control-Meta-2 to
1092     the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1093     font-switching at runtime:
1094    
1095     URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1096     URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1097    
1098     Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1099     info):
1100    
1101     URxvt.keysym.M-C-3: command:\033[8;25;80t

1110    
1111     Extension names can be prefixed with a C<-> sign to prohibit using
1112 root 1.91 them. This can be useful to selectively disable some extensions loaded
1113 root 1.88 by default, or specified via the C<perl-ext-common> resource. For
1114     example, C<default,-selection> will use all the default extension except
1115     C<selection>.
1116    
1117 root 1.91 Extension names can also be followed by an argument in angle brackets
1118     (e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1119 root 1.118 searchable scrollback to Alt/Meta-s). Mentioning the same extension
1120 root 1.91 multiple times with different arguments will pass multiple arguments to
1121     the extension.

1263     This allows you to enter unicode characters using their hexcode.
1264 root 1.2
1265 root 1.12 Start by pressing and holding both C<Control> and C<Shift>, then enter
1266     hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1267     commit the character as if it were typed directly. While holding down
1268     C<Control> and C<Shift> you can also enter multiple characters by pressing
1269     C<Space>, which will commit the current character and lets you start a new
1270     one.
1271    
1272     As an example of use, imagine a business card with a japanese e-mail
1273     address, which you cannot type. Fortunately, the card has the e-mail
1274     address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily

1285 root 1.114 invoke its usual function but instead will insert the corresponding
1286 root 1.12 keycap symbol. The symbol will only be entered when the key has been

1324    
1325     In addition to the default foreground and background colours,
1326 root 1.2 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1327 root 1.1 high-intensity bold/blink versions of the same). Here is a list of the
1328 root 1.107 colours with their names.
1329 root 1.1
1330     =begin table
1331    
1332     B<color0> (black) = Black
1333     B<color1> (red) = Red3
1334     B<color2> (green) = Green3
1335     B<color3> (yellow) = Yellow3
1336     B<color4> (blue) = Blue3
1337     B<color5> (magenta) = Magenta3
1338     B<color6> (cyan) = Cyan3
1339     B<color7> (white) = AntiqueWhite
1340     B<color8> (bright black) = Grey25
1341     B<color9> (bright red) = Red
1342     B<color10> (bright green) = Green
1343     B<color11> (bright yellow) = Yellow
1344     B<color12> (bright blue) = Blue
1345     B<color13> (bright magenta) = Magenta
1346     B<color14> (bright cyan) = Cyan
1347     B<color15> (bright white) = White
1348     B<foreground> = Black
1349     B<background> = White
1350    
1351     =end table
1352    
1353     It is also possible to specify the colour values of B<foreground>,
1354     B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1355     a number 0-15, as a convenient shorthand to reference the colour name of
1356     color0-color15.
1357    
1358 root 1.112 In addition to the colours defined above, @@RXVT_NAME@@ offers an
1359     additional 72 colours. The first 64 of those (with indices 16 to 79)
1360     consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
1361     16>), followed by 8 additional shades of gray (with indices 80 to 87).
1362    
1363     Together, all those colours implement the 88 colour xterm colours. Only
1364     the first 16 can be changed using resources currently, the rest can only
1365     be changed via command sequences ("escape codes").
1366    
1367 root 1.1 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1368     always swapping the foreground/background colours. This is in contrast to
1369     I<xterm>(1) where the colours are only swapped if they have not otherwise
1370     been specified. For example,
1371    
1372     =over 4
1373    
1374 root 1.3 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1375 root 1.1
1376     would yield White on Black, while on I<xterm>(1) it would yield Black
1377     on White.

1381 root 1.111 =head2 ALPHA CHANNEL SUPPORT
1382    
1383     If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1384     their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1385     (recommended, but B<MUST> have 4 digits/component) colour specifications,
1386     in addition to the ones provided by X, where the additional A component
1387     specifies opacity (alpha) values. The minimum value of C<0> is completely
1388 root 1.123 transparent). You can also prefix any color with C<[percent]>, where
1389     C<percent> is a decimal percentage (0-100) that specifies the opacity of
1390     the color, where C<0> is completely transparent and C<100> is completelxy
1391     opaque.
1392 root 1.111
1393     You probably need to specify B<"-depth 32">, too, and have the luck that
1394     your X-server uses ARGB pixel layout, as X is far from just supporting
1395     ARGB visuals out of the box, and rxvt-unicode just fudges around.
1396    
1397     For example, the following selects an almost completely transparent red
1398     background, and an almost opaque pink foreground:
1399    
1400 root 1.123 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/aaaa -fg "[80]pink"
1401 root 1.111

1403     the author. Don't bug him with installation questions!>

1425     the colour code used as default foreground/text colour (or the string
1426     C<default> to indicate that the default-colour escape sequence is to be
1427     used), C<bg> is the colour code used as default background colour (or the
1428     string C<default>), and C<xpm> is the string C<default> if @@RXVT_NAME@@
1429 root 1.54 was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
1430     (and do) use this information to optimize screen output.
