390which enables applications to easily embed a terminal.
391
392Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
393shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
394quite a bit, so don't expect it to keep some specific state. It's best to
395create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
396
397The window will not be destroyed when @@RXVT_NAME@@ exits.
398
399It might be useful to know that @@RXVT_NAME@@ will not close file
400descriptors passed to it (except for stdin/out/err, of course), so you
401can use file descriptors to communicate with the programs within the
402terminal. This works regardless of wether the C<-embed> option was used or
403not.
404
405Here is a short Gtk2-perl snippet that illustrates how this option can be
406used (a longer example is in F<doc/embed>):
407
408 my $rxvt = new Gtk2::Socket;
409 $rxvt->signal_connect_after (realize => sub {

417pair but instead use the given filehandle as the tty master. This is
418useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
419without having to run a program within it.
420
421If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
422entries and will not tinker with pty/tty permissions - you have to do that
423yourself if you want that.

942any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
943B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,

945B<2>, B<3>, B<4>, B<5>.
946
947The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
948whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
949keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
950current application keymap mode state.
951
952The spellings of I<key> can be obtained by using B<xev>(1) command or
953searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
954omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
955keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
956performed in an exact manner; however, the closest match is assured.
957
958I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
959C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
800tab, \000: octal number) or control characters (^?: delete, ^@: null, 960C<\000>: octal number) or verbatim control characters (C<^?>: delete,

803omitted. This resource is only available when compiled with 963
804KEYSYM_RESOURCE. 964Please note that you need to double the C<\> when using
965C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
966use C<\033> instead of C<\e> (and so on), which will work with both Xt and
967@@RXVT_NAME@@'s own processing).
968
969You can define a range of keysyms in one shot by providing a I<string>
970with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
971should be a character not used by the strings.
972
973Its usage can be demonstrated by an example:
974
975 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
976
977The above line is equivalent to the following three lines:
978
979 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
980 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
981 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
982
983If I<string> takes the form of C<command:STRING>, the specified B<STRING>
984is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
985example the following means "change the current locale to C<zh_CN.GBK>
986when Control-Meta-c is being pressed":
987
988 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
989
990Due the the large number of modifier combinations, a defined key mapping
991will match if at I<at least> the specified identifiers are being set, and
992no other key mappings with those and more bits are being defined. That
993means that defining a key map for C<a> will automatically provide
994definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
995mappings themselves.
996
997Unfortunately, this will override built-in key mappings. For example
998if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
999C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1000user-defined keymap using the C<builtin:> replacement:
1001
1002 URxvt.keysym.Insert: <my insert key sequence>
1003 URxvt.keysym.S-Insert: builtin:
1004
1005The first line defines a mapping for C<Insert> and I<any> combination
1006of modifiers. The second line re-establishes the default mapping for
1007C<Shift-Insert>.
1008
1009The following example will map Control-Meta-1 and Control-Meta-2 to
1010the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1011font-switching at runtime:
1012
1013 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1014 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1015
1016Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1017info):

1001 1225
1002The correct solution for this problem is to install the terminfo, this can be done 1226=item B<COLORFGBG>
1003like this:
1004 1227
1005 infocmp rxvt-unicode >rxvt.unicode.tic 1228Set to a string of the form C<fg;bg> or C<fg;xpm;bg>, where C<fg> is

1007 ssh remotesystem tic rxvt-unicode.tic 1230C<default> to indicate that the default-colour escape sequence is to be

1233was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
1234(and do) use this information to optimize screen output.
1010 1235
1011If you cannot or do not want to do this, then you can simply set 1236=item B<WINDOWID>
1012C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
1013problems arising, which includes wrong keymapping, less and different
1014colours and some refresh errors in fullscreen applications. It's a nice
1015quick-and-dirty workaround for rare cases, though.
1016 1237
1017If you always want to do this you can either recompile rxvt-unicode with 1238Set to the (decimal) X Window ID of the @@RXVT_NAME@@ window (the toplevel
1018the desired TERM value or use a resource to set it: 1239window, which usually has subwindows for the scrollbar, the terminal

1022=item How can I configure rxvt-unicode so that it looks similar to the original rxvt? 1244Set to the terminfo directory iff @@RXVT_NAME@@ was configured with
1245C<--with-terminfo=PATH>.
1023 1246
1024Felix von Leitner says that these two lines, in your F<.Xdefaults>, will make rxvt-unicode 1247=item B<DISPLAY>

1034If you encounter strange problems like typing an accented character but 1256=item B<RXVTPATH>
1035getting two unrelated other characters or similar, or if program output is
1036subtly garbled, then you should check your locale settings.
1037 1257
1038Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the 1258The path where @@RXVT_NAME@@ looks for support files such as menu and xpm
1039programs. Often rxvt-unicode is started in the C<C> locale, while the 1259files.
1040login script running within the rxvt-unicode window changes the locale to
1041sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
1042 1260
1043The best thing is to fix your startup environment, as you will likely run 1261=item B<PATH>
1044into other problems. If nothing works you can try this in your .profile.
1045 1262
1046 printf '\e]701;%s\007' "$LC_CTYPE" 1263Used in the same way as C<RXVTPATH>.
1047 1264
1048If this doesn't work, then maybe you use a C<LC_CTYPE> specification not 1265=item B<RXVT_SOCKET>
1049supported on your systems. Some systems have a C<locale> comamnd which
1050displays this. If it displays sth. like:
1051 1266
1052 locale: Cannot set LC_CTYPE to default locale: ... 1267The unix domain socket path used by @@RXVT_NAME@@c(1) and
1268@@RXVT_NAME@@d(1).

1054Then the locale you specified is not supported on your system. 1270Default F<<< $HOME/.rxvt-unicode-I<< <nodename >> >>>.

1056If nothing works and you are sure that everything is set correctly then 1272=item B<HOME>
1057you will need to remember a little known fact: Some programs just don't
1058support locales :(
1059 1273
1060=item Why do the characters look ugly? 1274Used to locate the default directory for the unix domain socket for

1063 1279
1064Most fonts do not contain the full range of Unicode, which is 1280Directory where various X resource files are being located.
1065fine. Chances are that the font you (or the admin/package maintainer of
1066your system/os) have specified does not cover all the characters you want
1067to display.
1068 1281
1069B<rxvt-unicode> makes a best-effort try at finding a replacement 1282=item B<XENVIRONMENT>
1070font. Often the result is fine, but sometimes the chosen font looks
1071bad. Many fonts have totally strange characters that don't resemble the
1072correct glyph at all, and rxvt-unicode lacks the artificial intelligence
1073to detetc that a specific glyph is wrong: it has to believe the font that
1074the characters it contains indeed look correct.
1075 1283
1076In that case, select a font of your taste and add it to the font list, 1284If set and accessible, gives the name of a X resource file to be loaded by
1077e.g.:
1078
1079 @@RXVT_NAME@@ -fn basefont,font2,font3...
1080
1081When rxvt-unicode sees a character, it will first look at the base
1082font. If the base font does not contain the character, it will go to the
1083next font, and so on. Specifying your own fonts will also speed up this
1084search and use less resources within rxvt-unicode and the X-server.
1085
1086The only limitation is that all the fonts must not be larger than the base
1087font, as the base font defines the principial cell size, which must be the
1088same due to the way terminals work.
1089
1090=item Why do some chinese characters look so different than others?
1091
1092This is because there is a difference between script and language --
1093rxvt-unicode does not know which language the text that is output
1094is, as it only knows the unicode character codes. If rxvt-unicode
1095first sees a japanese character, it might choose a japanese font for
1096it. Subseqzuent japanese characters will take that font. Now, many chinese
1097characters aren't represented in japanese fonts, so when the first
1098non-japanese character comes up, rxvt-unicode will look for a chinese font
1099-- unfortunately at this point, it will still use the japanese font for
1100japanese characters that are also chinese.
1101
1102The workaround is easy: just tag a chinese font at the end of your font
1103list (see the previous question). The key is to view the font list as
1104a preference list: If you expect more japanese, list a japanese font
1105first. If you expect more chinese, put a chinese font first.
1106
1107In the future it might be possible to switch preferences at runtime (the
1108internal data structure has no problem with using different fonts for
1109the same character at the same time, but no interface for this has been
1110designed yet).
1111
1112=item How can I keep rxvt-unicode from using reverse video so much?
1113
1114First of all, make sure you are running with the right terminfo
1115(C<urxvt>), which will get rid of most of these effects. Then make sure
1116you have specified colours for italic and bold, as otherwise rxvt-unicode
1117might use reverse video to simulate the effect:
1118
1119 URxvt*colorBD: white
1120 URxvt*colorIT: green
1121
1122=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
1123
1124For some unexplainable reason, some programs (i.e. irssi) assume a very
1125weird colour palette when confronted with a terminal with more than the
1126standard 8 colours (rxvt-unicode supports 88). The right fix is, of
1127course, to fix these programs not to assume non-ISO colours without very
1128good reasons.
1129
1130In the meantime, you can either edit your C<urxvt> terminfo definition to
1131only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
1132but keep you from using other rxvt-unicode features.
1133
1134=item How does rxvt-unicode determine the encoding to use?
1135
1136=item Is there an option to switch encodings?
1137
1138Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1139specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1140UTF-8 or any other encodings with respect to terminal I/O.
1141
1142The reasons is that there exists a perfectly fine mechanism for selecting
1143the encoding, doing I/O and (most important) communicating this to all
1144applications so everybody agrees on character properties such as width and
1145code number. This mechanism is the I<locale>.
1146
1147Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1148programs doing the same (that is, most) will automatically agree in the
1149interpretation of characters.
1150
1151Unfortunately, there is no system-independent way to select locales, nor
1152is there a standard on how locale specifiers will look like.
1153
1154On most systems, the content of the C<LC_CTYPE> environment variable
1155contains an arbitrary string which corresponds to an already-installed
1156locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1157C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1158(i.e. C<de> or C<german>) are also common.
1159
1160Rxvt-unicode ignores all other locale categories, and except for
1161the encoding, ignores country or language-specific settings,
1162i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1163
1164If you want to use a specific encoding you have to make sure you start
1165rxvt-unicode with the correct C<LC_CTYPE> category.
1166
1167=item Can I switch locales at runtime?
1168
1169Yes, using an escape sequence. Try sth. like this, which sets
1170rxvt-unicode's idea of C<LC_CTYPE>.
1171
1172 printf '\e]701;%s\007' ja_JP.SJIS
1173
1174See also the previous question.
1175
1176Sometimes this capability is rather handy when you want to work in one
1177locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1178example, I use this script to start C<xjdic>, which first switches to a
1179locale supported by xjdic and back later:
1180
1181 printf '\e]701;%s\007' ja_JP.SJIS
1182 xjdic -js
1183 printf '\e]701;%s\007' de_DE.UTF-8
1184
1185=item Can I switch the fonts at runtime?
1186
1187Yes, using an escape sequence. Try sth. like this, which has the same
1188effect as using the C<-fn> switch, and takes effect immediately:
1189
1190 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1191
1192This is useful if you e.g. work primarily with japanese (and prefer a
1193japanese font), but you have to switch to chinese temporarily, where
1194japanese fonts would only be in your way.
1195
1196You can think of this as a kind of manual ISO-2022 switching.
1197
1198=item Why do italic characters look as if clipped?
1199
1200Many fonts have difficulties with italic characters and hinting. For
1201example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
1202Mono> completely fails in it's italic face. A workaround is to enable
1203freetype autohinting, i.e. like this:
1204
1205 URxvt*italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
1206 URxvt*boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
1207
1208=item My input method wants <some encoding> but I want UTF-8, what can I do?
1209
1210You cna specify separate locales for the input method and the rest of the
1211terminal, using the resource C<imlocale>:
1212
1213 URxvt*imlocale: ja_JP.EUC-JP
1214
1215Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1216use your input method. Please note, however, that you will not be able to
1217input characters outside C<EUC-JP> in a normal way then, as your input
1218method limits you.
1219
1220=item Rxvt-unicode uses gobs of memory, how can I reduce that?
1221
1222Rxvt-unicode tries to obey the rule of not charging you for sth. you
1223don't use. One thing you should try is to configure out all settings that
1224you don't need, for example, Xft support is a resource hog by design,
1225when used. Compiling it out ensures that no Xft font will be loaded
1226accidentally when rxvt-unicode tries to find a font for your characters.
1227
1228Also, many people (me included) like large windows and even larger
1229scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
12306 bytes per screen cell. For a 160x?? window this amounts to almost a
1231kilobyte per line. A scorllback buffer of 10000 lines will then (if full)
1232use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
1233rxvt-unicode then uses 8 bytes per screen cell.
1234
1235=item Can I speed up Xft rendering somehow?
1236
1237Yes, the most obvious way to speed it up is to avoid Xft entirely, as
1238it is simply slow. If you still want Xft fonts you might try to disable
1239antialiasing (by appending C<:antialiasing=false>), which saves lots of
1240memory and also speeds up rendering considerably.
1241
1242=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
1243
1244Rxvt-unicode will use whatever you specify as a font. If it needs to
1245fall back to it's default font search list it will prefer X11 core
1246fonts, because they are small and fast, and then use Xft fonts. It has
1247antialiaisng disabled for most of them, because the author thinks they
1248look best that way.
1249
1250If you want antialiasing, you have to specify the fonts manually.
1251
1252=item Mouse cut/paste suddenly no longer works.
1253
1254Make sure that mouse reporting is actually turned off since killing
1255some editors prematurely may leave the mouse in mouse report mode. I've
1256heard that tcsh may use mouse reporting unless it otherwise specified. A
1257quick check is to see if cut/paste works when the Alt or Shift keys are
1258depressed. See @@RXVT_NAME@@(7)
1259
1260=item What's with this bold/blink stuff?
1261
1262If no bold colour is set via C<colorBD:>, bold will invert text using the
1263standard foreground colour.
1264
1265For the standard background colour, blinking will actually make the
1266text blink when compiled with C<--enable-blinking>. with standard
1267colours. Without C<--enable-blinking>, the blink attribute will be
1268ignored.
1269
1270On ANSI colours, bold/blink attributes are used to set high-intensity
1271foreground/background colors.
1272
1273color0-7 are the low-intensity colors.
1274
1275color8-15 are the corresponding high-intensity colors.
1276
1277=item I don't like the screen colors. How do I change them?
1278
1279You can change the screen colors at run-time using F<~/.Xdefaults>
1280resources (or as long-options).
1281
1282Here are values that are supposed to resemble a VGA screen,
1283including the murky brown that passes for low-intensity yellow:
1284
1285 Rxvt*color0: #000000
1286 Rxvt*color1: #A80000
1287 Rxvt*color2: #00A800

1295 Rxvt*color9: #FF0054
1296 Rxvt*color10: #00FF54
1297 Rxvt*color11: #FFFF54
1298 Rxvt*color12: #0000FF
1299 Rxvt*color13: #FF00FF
1300 Rxvt*color14: #00FFFF
1301 Rxvt*color15: #FFFFFF
1302
1303=item What's with the strange Backspace/Delete key behaviour?
1304
1305Assuming that the physical Backspace key corresponds to the
1306BackSpace keysym (not likely for Linux ... see the following
1307question) there are two standard values that can be used for
1308Backspace: C<^H> and C<^?>.
1309
1310Historically, either value is correct, but rxvt-unicode adopts the debian
1311policy of using C<^?> when unsure, because it's the one only only correct
1312choice :).
1313
1314Rxvt-unicode tries to inherit the current stty settings and uses the value
1315of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1316started from a terminal (say, from a menu or by remote shell), then the
1317system value of `erase', which corresponds to CERASE in <termios.h>, will
1318be used (which may not be the same as your stty setting).
1319
1320For starting a new rxvt-unicode:
1321
1322 # use Backspace = ^H
1323 $ stty erase ^H
1324 $ @@RXVT_NAME@@ 1285@@RXVT_NAME@@.
1325
1326 # use Backspace = ^?
1327 $ stty erase ^?
1328 $ @@RXVT_NAME@@
1329
1330Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1331
1332For an existing rxvt-unicode:
1333
1334 # use Backspace = ^H
1335 $ stty erase ^H
1336 $ echo -n "^[[36h"
1337
1338 # use Backspace = ^?
1339 $ stty erase ^?
1340 $ echo -n "^[[36l"
1341
1342This helps satisfy some of the Backspace discrepancies that occur, but
1343if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1344properly reflects that.
1345
1346The Delete key is a another casualty of the ill-defined Backspace problem.
1347To avoid confusion between the Backspace and Delete keys, the Delete
1348key has been assigned an escape sequence to match the vt100 for Execute
1349(ESC[3~) and is in the supplied termcap/terminfo.
1350
1351Some other Backspace problems:
1352
1353some editors use termcap/terminfo,
1354some editors (vim I'm told) expect Backspace = ^H,
1355GNU Emacs (and Emacs-like editors) use ^H for help.
1356
1357Perhaps someday this will all be resolved in a consistent manner.
1358
1359=item I don't like the key-bindings. How do I change them?
1360
1361There are some compile-time selections available via configure. Unless
1362you have run "configure" with the C<--disable-resources> option you can
1363use the `keysym' resource to alter the keystrings associated with keysym
13640xFF00 - 0xFFFF (function, cursor keys, etc).

1407=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
1408How do I make use of them? For example, the Sun Keyboard type 4
1409has the following mappings that rxvt-unicode doesn't recognize.
1410
1411 KP_Insert == Insert
1412 F22 == Print
1413 F27 == Home
1414 F29 == Prior
1415 F33 == End
1416 F35 == Next
1417
1418Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1419mappings, it is better to use `xmodmap' to remap the keys as required for
1420your particular machine.
1421
1422=item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1423I need this to decide about setting colors etc.
1424
1425rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1426check and see if that is set. Note that several programs, JED, slrn,
1427Midnight Commander automatically check this variable to decide whether or
1428not to use color.
1429
1430=item How do I set the correct, full IP address for the DISPLAY variable?
1431
1432If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1433insecure mode then it is possible to use the following shell script
1434snippets to correctly set the display. If your version of rxvt-unicode
1435wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1436the COLORTERM variable can be used to distinguish rxvt-unicode from a
1437regular xterm.

1456
1457You need to have a recent version of perl installed as F</usr/bin/perl>,
1458one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
1459the doc subdirectory and enter C<make alldoc>.
