381
382Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
383shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
384quite a bit, so don't expect it to keep some specific state. It's best to
385create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
386
387The window will not be destroyed when @@RXVT_NAME@@ exits.
388
389It might be useful to know that @@RXVT_NAME@@ will not close file
390descriptors passed to it (except for stdin/out/err, of course), so you
391can use file descriptors to communicate with the programs within the
392terminal. This works regardless of wether the C<-embed> option was used or
393not.
394
395Here is a short Gtk2-perl snippet that illustrates how this option can be
396used (a longer example is in F<doc/embed>):

410
411If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp

627the iso8859-1 version of the second font), which is the base font (because
628it is named first) and thus defines the character cell grid to be 9 pixels
629wide and 15 pixels high.
630
631The second font is just used to add additional unicode characters not in
632the base font, likewise the third, which is unfortunately non-bold, but
633the bold version of the font does contain less characters, so this is a
634useful supplement.
635
636The third font is an Xft font with aliasing turned off, and the characters
637are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
638contains other characters, but we are not interested in them.

918B<2>, B<3>, B<4>, B<5>.
919
920The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
921whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
922keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
923current application keymap mode state.
924
925The spellings of I<key> can be obtained by using B<xev>(1) command or
926searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
927omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
928keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
929performed in an exact manner; however, the closest match is assured.

739KEYSYM_RESOURCE. 937Please note that you need to double the C<\> when using
938C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
939use C<\033> instead of C<\e> (and so on), which will work with both Xt and
940@@RXVT_NAME@@'s own processing).
941
942You can define a range of keysyms in one shot by providing a I<string>
943with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
944should be a character not used by the strings.
945
946Its usage can be demonstrated by an example:
947
948 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
949
950The above line is equivalent to the following three lines:
951
952 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
953 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
954 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
955
956If I<string> takes the form of C<command:STRING>, the specified B<STRING>
957is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
958example the following means "change the current locale to C<zh_CN.GBK>
959when Control-Meta-c is being pressed":
960
961 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
962
963Due the the large number of modifier combinations, a defined key mapping
964will match if at I<at least> the specified identifiers are being set, and
965no other key mappings with those and more bits are being defined. That
966means that defining a key map for C<a> will automatically provide
967definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
968mappings themselves.
969
970Unfortunately, this will override built-in key mappings. For example
971if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
972C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
973user-defined keymap using the C<builtin:> replacement:
974
975 URxvt.keysym.Insert: <my insert key sequence>
976 URxvt.keysym.S-Insert: builtin:
977
978The first line defines a mapping for C<Insert> and I<any> combination
979of modifiers. The second line re-establishes the default mapping for
980C<Shift-Insert>.
981
982The following example will map Control-Meta-1 and Control-Meta-2 to
983the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
984font-switching at runtime:
985
986 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
987 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
988
989Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
990info):

976next font, and so on.
977 1237
978The only limitation is that all the fonts must not be larger than the base 1238=item B<RXVT_SOCKET>
979font, as the base font defines the principial cell size, which must be the
980same due to the way terminals work.
981 1239
982=item Why do some chinese characters look so different than others? 1240The unix domain socket path used by @@RXVT_NAME@@c(1) and
1241@@RXVT_NAME@@d(1).
983 1242
984This is because there is a difference between script and language -- 1243Default C<< $HOME/.rxvt-unicode-<nodename >>.
985rxvt-unicode does not know which language the text that is output
986is, as it only knows the unicode character codes. If rxvt-unicode
987first sees a japanese character, it might choose a japanese font for
988it. Subseqzuent japanese characters will take that font. Now, many chinese
989characters aren't represented in japanese fonts, so when the first
990non-japanese character comes up, rxvt-unicode will look for a chinese font
991-- unfortunately at this point, it will still use the japanese font for
992japanese characters that are also chinese.
993 1244
994The workaround is easy: just tag a chinese font at the end of your font 1245=item B<HOME>
995list (see the previous question). The key is to view the font list as
996a preference list: If you expect more japanese, list a japanese font
997first. If you expect more chinese, put a chinese font first.
998 1246
999In the future it might be possible to switch preferences at runtime (the 1247Used to locate the default directory for the unix domain socket for
1000internal data structure has no problem with using different fonts for 1248daemon communications and to locate various resource files (such as
1001the same character at the same time, but no interface for this has been 1249C<.Xdefaults>)
1002designed yet).
1003 1250
1004=item How does rxvt-unicode determine the encoding to use? 1251=item B<XAPPLRESDIR>
1005 1252
1006=item Is there an option to switch encodings? 1253Directory where various X resource files are being located.
1007 1254
1008Unlike some other terminals, rxvt-unicode has no encoding switch, and no 1255=item B<XENVIRONMENT>
1009specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1010UTF-8 or any other encodings with respect to terminal I/O.
1011 1256
1012The reasons is that there exists a perfectly fine mechanism for selecting 1257If set and accessible, gives the name of a X resource file to be loaded by
1013the encoding, doing I/O and (most important) communicating this to all
1014applications so everybody agrees on character properties such as width and
1015code number. This mechanism is the I<locale>.
1016
1017Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1018programs doing the same (that is, most) will automatically agree in the
1019interpretation of characters.
1020
1021Unfortunately, there is no system-independent way to select locales, nor
1022is there a standard on how locale specifiers will look like.
1023
1024On most systems, the content of the C<LC_CTYPE> environment variable
1025contains an arbitrary string which corresponds to an already-installed
1026locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1027C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1028(i.e. C<de> or C<german>) are also common.
1029
1030Rxvt-unicode ignores all other locale categories, and except for
1031the encoding, ignores country or language-specific settings,
1032i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1033
1034If you want to use a specific encoding you have to make sure you start
1035rxvt-unicode with the correct C<LC_CTYPE> category.
1036
1037=item Can I switch locales at runtime?
1038
1039Yes, using an escape sequence. Try sth. like this, which sets
1040rxvt-unicode's idea of C<LC_CTYPE>.
1041
1042 printf '\e]701;%s\007' ja_JP.SJIS
1043
1044See also the previous question.
1045
1046Sometimes this capability is rather handy when you want to work in one
1047locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1048example, I use this script to start C<xjdic>, which first switches to a
1049locale supported by xjdic and back later:
1050
1051 printf '\e]701;%s\007' ja_JP.SJIS
1052 xjdic -js
1053 printf '\e]701;%s\007' de_DE.UTF-8
1054
1055=item Can I switch the fonts at runtime?
1056
1057Yes, using an escape sequence. Try sth. like this, which has the same
1058effect as using the C<-fn> switch, and takes effect immediately:
1059
1060 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1061
1062This is useful if you e.g. work primarily with japanese (and prefer a
1063japanese font), but you have to switch to chinese temporarily, where
1064japanese fonts would only be in your way.
1065
1066You can think of this as a kind of manual ISO-2022 switching.

1068=item Mouse cut/paste suddenly no longer works.
1069
1070Make sure that mouse reporting is actually turned off since killing
1071some editors prematurely may leave the mouse in mouse report mode. I've
1072heard that tcsh may use mouse reporting unless it otherwise specified. A
1073quick check is to see if cut/paste works when the Alt or Shift keys are
1074depressed. See @@RXVT_NAME@@(7)
1075
1076=item What's with this bold/blink stuff?
1077
1078If no bold colour is set via C<colorBD:>, bold will invert text using the
1079standard foreground colour.
1080
1081For the standard background colour, blinking will actually make the
1082text blink when compiled with C<--enable-blinking>. with standard
1083colours. Without C<--enable-blinking>, the blink attribute will be
1084ignored.
1085
1086On ANSI colours, bold/blink attributes are used to set high-intensity
1087foreground/background colors.
1088
1089color0-7 are the low-intensity colors.
1090
1091color8-15 are the corresponding high-intensity colors.
1092
1093=item I don't like the screen colors. How do I change them?
1094
1095You can change the screen colors at run-time using F<~/.Xdefaults>
1096resources (or as long-options).
1097
1098Here are values that are supposed to resemble a VGA screen,
1099including the murky brown that passes for low-intensity yellow:
1100
1101 Rxvt*color0: #000000

1118
1119=item What's with the strange Backspace/Delete key behaviour?
1120
1121Assuming that the physical Backspace key corresponds to the
1122BackSpace keysym (not likely for Linux ... see the following
1123question) there are two standard values that can be used for
1124Backspace: C<^H> and C<^?>.
1125
1126Historically, either value is correct, but rxvt-unicode adopts the debian
1127policy of using C<^?> when unsure, because it's the one only only correct
1128choice :).
1129
1130Rxvt-unicode tries to inherit the current stty settings and uses the value
1131of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1132started from a terminal (say, from a menu or by remote shell), then the
1133system value of `erase', which corresponds to CERASE in <termios.h>, will
1134be used (which may not be the same as your stty setting).
1135
1136For starting a new rxvt-unicode:
1137
1138 # use Backspace = ^H
1139 $ stty erase ^H
1140 $ @@RXVT_NAME@@ 1258@@RXVT_NAME@@.
1141
1142 # use Backspace = ^?
1143 $ stty erase ^?
1144 $ @@RXVT_NAME@@
1145
1146Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1147
1148For an existing rxvt-unicode:
1149
1150 # use Backspace = ^H
1151 $ stty erase ^H
1152 $ echo -n "^[[36h"
1153
1154 # use Backspace = ^?
1155 $ stty erase ^?
1156 $ echo -n "^[[36l"
1157
1158This helps satisfy some of the Backspace discrepancies that occur, but
1159if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1160properly reflects that.
1161
1162The Delete key is a another casualty of the ill-defined Backspace problem.
1163To avoid confusion between the Backspace and Delete keys, the Delete
1164key has been assigned an escape sequence to match the vt100 for Execute
1165(ESC[3~) and is in the supplied termcap/terminfo.
1166
1167Some other Backspace problems:
1168
1169some editors use termcap/terminfo,
1170some editors (vim I'm told) expect Backspace = ^H,
1171GNU Emacs (and Emacs-like editors) use ^H for help.
1172
1173Perhaps someday this will all be resolved in a consistent manner.
1174
1175=item I don't like the key-bindings. How do I change them?
1176
1177There are some compile-time selections available via configure. Unless
1178you have run "configure" with the C<--disable-resources> option you can
1179use the `keysym' resource to alter the keystrings associated with keysym
11800xFF00 - 0xFFFF (function, cursor keys, etc).

1228 F22 == Print
1229 F27 == Home
1230 F29 == Prior
1231 F33 == End
1232 F35 == Next
1233
1234Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1235mappings, it is better to use `xmodmap' to remap the keys as required for
1236your particular machine.
1237
1238=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1239I need this to decide about setting colors etc.
1240
1241rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1242check and see if that is set. Note that several programs, JED, slrn,
1243Midnight Commander automatically check this variable to decide whether or
1244not to use color.
1245
1246=item How do I set the correct, full IP address for the DISPLAY variable?
1247
1248If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1249insecure mode then it is possible to use the following shell script
1250snippets to correctly set the display. If your version of rxvt-unicode
1251wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1252the COLORTERM variable can be used to distinguish rxvt-unicode from a
1253regular xterm.
