455which enables applications to easily embed a terminal.
456
457Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
458shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
459quite a bit, so don't expect it to keep some specific state. It's best to
460create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
461
462The window will not be destroyed when @@RXVT_NAME@@ exits.
463
464It might be useful to know that @@RXVT_NAME@@ will not close file
465descriptors passed to it (except for stdin/out/err, of course), so you
466can use file descriptors to communicate with the programs within the
467terminal. This works regardless of whether the C<-embed> option was used or
468not.
469
470Here is a short Gtk2-perl snippet that illustrates how this option can be
471used (a longer example is in F<doc/embed>):
472
473 my $rxvt = new Gtk2::Socket;
474 $rxvt->signal_connect_after (realize => sub {
475 my $xid = $_[0]->window->get_xid;
476 system "@@RXVT_NAME@@ -embed $xid &";

480
481Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
482pair but instead use the given file descriptor as the tty master. This is
483useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
484without having to run a program within it.
485
486If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
487entries and will not tinker with pty/tty permissions - you have to do that
488yourself if you want that.
489
490As an extremely special case, specifying C<-1> will completely suppress
491pty/tty operations.
492
493Here is a example in perl that illustrates how this option can be used (a
494longer example is in F<doc/pty-fd>):
495
496 use IO::Pty;
497 use Fcntl;
498
499 my $pty = new IO::Pty;
500 fcntl $pty, F_SETFD, 0; # clear close-on-exec
501 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
502 close $pty;
503
504 # now communicate with rxvt

1071The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1072any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1073B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1074and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1075B<2>, B<3>, B<4>, B<5>.
1076
1077The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1078whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1079keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1080current application keymap mode state.
1081
1082The spellings of I<key> can be obtained by using B<xev>(1) command or
1083searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1084omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1085keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1086performed in an exact manner; however, the closest match is assured.
1087
1088I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
1089C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
800tab, \000: octal number) or control characters (^?: delete, ^@: null, 1090C<\000>: octal number) or verbatim control characters (C<^?>: delete,
801^A ...) and may enclosed with double quotes so that it can start or end 1091C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it

803omitted. This resource is only available when compiled with 1093be removed>.
804KEYSYM_RESOURCE. 1094
1095Please note that you need to double the C<\> in resource files, as
1096Xlib itself does its own de-escaping (you can use C<\033> instead of
1097C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own
1098processing).
1099
1100You can define a range of keysyms in one shot by providing a I<string>
1101with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1102should be a character not used by the strings.
1103
1104Its usage can be demonstrated by an example:
1105
1106 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1107
1108The above line is equivalent to the following three lines:
1109
1110 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1111 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1112 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1113
1114If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1115is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1116example the following means "change the current locale to C<zh_CN.GBK>
1117when Control-Meta-c is being pressed":
1118
1119 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1120
1121If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1122is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1123manpage. For example, the F<selection> extension (activated via
1124C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1125
1126 URxvt.keysym.M-C-c: perl:selection:rot13
1127
1128Due the the large number of modifier combinations, a defined key mapping
1129will match if at I<at least> the specified identifiers are being set, and
1130no other key mappings with those and more bits are being defined. That
1131means that defining a key map for C<a> will automatically provide
1132definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1133mappings themselves.
1134
1135Unfortunately, this will override built-in key mappings. For example
1136if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1137C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1138user-defined keymap using the C<builtin:> replacement:
1139
1140 URxvt.keysym.Insert: <my insert key sequence>
1141 URxvt.keysym.S-Insert: builtin:
1142
1143The first line defines a mapping for C<Insert> and I<any> combination
1144of modifiers. The second line re-establishes the default mapping for
1145C<Shift-Insert>.
1146
1147The following example will map Control-Meta-1 and Control-Meta-2 to
1148the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1149font-switching at runtime:
1150
1151 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1152 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1153
1154Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1155info):
1156
1157 URxvt.keysym.M-C-3: command:\033[8;25;80t

1164Comma-separated list(s) of perl extension scripts (default: C<default>) to
1165use in this terminal instance; option B<-pe>.
1166
1167Extension names can be prefixed with a C<-> sign to prohibit using
1168them. This can be useful to selectively disable some extensions loaded
1169by default, or specified via the C<perl-ext-common> resource. For
1170example, C<default,-selection> will use all the default extension except
1171C<selection>.
1172
1173Extension names can also be followed by an argument in angle brackets
1174(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1175searchable scrollback to Alt/Meta-s). Mentioning the same extension
1176multiple times with different arguments will pass multiple arguments to
1177the extension.
1178
1179Each extension is looked up in the library directories, loaded if
1180necessary, and bound to the current terminal instance.
1181
1182If both of these resources are the empty string, then the perl
1183interpreter will not be initialized. The idea behind two options is that
1184B<perl-ext-common> will be used for extensions that should be available to

1443If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1444their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1445(recommended, but B<MUST> have 4 digits/component) colour specifications,
1446in addition to the ones provided by X, where the additional A component
1447specifies opacity (alpha) values. The minimum value of C<0> is completely
1448transparent). You can also prefix any color with C<[percent]>, where
1449C<percent> is a decimal percentage (0-100) that specifies the opacity of
1450the color, where C<0> is completely transparent and C<100> is completelxy
1451opaque.
1452
1453You probably need to specify B<"-depth 32">, too, and have the luck that
1454your X-server uses ARGB pixel layout, as X is far from just supporting
1455ARGB visuals out of the box, and rxvt-unicode just fudges around.

1491and C<slang> can (and do) use this information to optimize screen output.
1010 1492
1011If you cannot or do not want to do this, then you can simply set 1493=item B<WINDOWID>

1038Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the 1515The unix domain socket path used by @@RXVT_NAME@@c(1) and

1043The best thing is to fix your startup environment, as you will likely run 1518Default F<<< $HOME/.rxvt-unicode-I<< <nodename >> >>>.

1045 1519
1046 printf '\e]701;%s\007' "$LC_CTYPE" 1520=item B<HOME>

1048If this doesn't work, then maybe you use a C<LC_CTYPE> specification not 1522Used to locate the default directory for the unix domain socket for

1061
1062=item How does rxvt-unicode choose fonts?
1063
1064Most fonts do not contain the full range of Unicode, which is
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
1069B<rxvt-unicode> makes a best-effort try at finding a replacement
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
1076In that case, select a font of your taste and add it to the font list,
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.

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
1288 Rxvt*color3: #A8A800
1289 Rxvt*color4: #0000A8
1290 Rxvt*color5: #A800A8
1291 Rxvt*color6: #00A8A8
1292 Rxvt*color7: #A8A8A8
1293
1294 Rxvt*color8: #000054
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@@ 1533@@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).
1365
1366Here's an example for a tn3270 session started using `@@RXVT_NAME@@ -name tn3270'
1367
1368 !# ----- special uses ------:
1369 ! tn3270 login, remap function and arrow keys.
1370 tn3270*font: *clean-bold-*-*--15-*

1406
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.
1438
