25 =head1 FREQUENTLY ASKED QUESTIONS
29 =item The new selection selects pieces that are too big, how can I select
32 Yes. For example, if you want to select alphanumeric words, you can use
33 the following resource:
35 URxvt.selection.pattern-0: ([[:word:]]+)
37 If you click more than twice, the selection will be extended
40 To get a selection that is very similar to the old code, try this pattern:
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
44 Please also note that the I<LeftClick Shift-LeftClik> combination also
45 selects words like the old code.
47 =item I don't like the new selection/popups/hotkeys/perl, how do I
50 You can disable the perl extension completely by setting the
51 B<perl-ext-common> resource to the empty string, which also keeps
52 rxvt-unicode from initialising perl, saving memory.
54 If you only want to disable specific features, you first have to
55 identify which perl extension is responsible. For this, read the section
56 B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57 example, to disable the B<selection-popup> and B<option-popup>, specify
58 this B<perl-ext-common> resource:
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup
62 This will keep the default extensions, but disable the two popup
63 extensions. Some extensions can also be configured, for example,
64 scrollback search mode is triggered by B<M-s>. You can move it to any
65 other combination either by setting the B<searchable-scrollback> resource:
67 URxvt.searchable-scrollback: CM-s
69 =item Isn't rxvt supposed to be small? Don't all those features bloat?
71 I often get asked about this, and I think, no, they didn't cause extra
72 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
73 that the urxvt binary is larger (due to some encoding tables always being
74 compiled in), but it actually uses less memory (RSS) after startup. Even
75 with C<--disable-everything>, this comparison is a bit unfair, as many
76 features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
77 already in use in this mode.
79 text data bss drs rss filename
80 98398 1664 24 15695 1824 rxvt --disable-everything
81 188985 9048 66616 18222 1788 urxvt --disable-everything
83 When you C<--enable-everything> (which _is_ unfair, as this involves xft
84 and full locale/XIM support which are quite bloaty inside libX11 and my
85 libc), the two diverge, but not unreasnobaly so.
87 text data bss drs rss filename
88 163431 2152 24 20123 2060 rxvt --enable-everything
89 1035683 49680 66648 29096 3680 urxvt --enable-everything
91 The very large size of the text section is explained by the east-asian
92 encoding tables, which, if unused, take up disk space but nothing else
93 and can be compiled out unless you rely on X11 core fonts that use those
94 encodings. The BSS size comes from the 64k emergency buffer that my c++
95 compiler allocates (but of course doesn't use unless you are out of
96 memory). Also, using an xft font instead of a core font immediately adds a
97 few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
100 Of course, due to every character using two or four bytes instead of one,
101 a large scrollback buffer will ultimately make rxvt-unicode use more
104 Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
105 still fares rather well. And compared to some monsters like gnome-terminal
106 (21152k + extra 4204k in separate processes) or konsole (22200k + extra
107 43180k in daemons that stay around after exit, plus half a minute of
108 startup time, including the hundreds of warnings it spits out), it fares
111 =item Why C++, isn't that unportable/bloated/uncool?
113 Is this a question? :) It comes up very often. The simple answer is: I had
114 to write it, and C++ allowed me to write and maintain it in a fraction
115 of the time and effort (which is a scarce resource for me). Put even
116 shorter: It simply wouldn't exist without C++.
118 My personal stance on this is that C++ is less portable than C, but in
119 the case of rxvt-unicode this hardly matters, as its portability limits
120 are defined by things like X11, pseudo terminals, locale support and unix
121 domain sockets, which are all less portable than C++ itself.
123 Regarding the bloat, see the above question: It's easy to write programs
124 in C that use gobs of memory, an certainly possible to write programs in
125 C++ that don't. C++ also often comes with large libraries, but this is
126 not necessarily the case with GCC. Here is what rxvt links against on my
127 system with a minimal config:
129 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
130 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
131 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
132 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
134 And here is rxvt-unicode:
136 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
137 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
138 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
139 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
140 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
142 No large bloated libraries (of course, none were linked in statically),
143 except maybe libX11 :)
145 =item Does it support tabs, can I have a tabbed rxvt-unicode?
147 rxvt-unicode does not directly support tabs. It will work fine with
148 tabbing functionality of many window managers or similar tabbing programs,
149 and its embedding-features allow it to be embedded into other programs,
150 as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
151 module, which features a tabbed urxvt (murxvt) terminal as an example
152 embedding application.
154 =item How do I know which rxvt-unicode version I'm using?
156 The version number is displayed with the usage (-h). Also the escape
157 sequence C<ESC [ 8 n> sets the window title to the version number. When
158 using the @@RXVT_NAME@@c client, the version displayed is that of the
161 =item I am using Debian GNU/Linux and have a problem...
163 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
164 patches that considerably change the behaviour of rxvt-unicode (but
165 unfortunately this notice has been removed). Before reporting a bug to
166 the original rxvt-unicode author please download and install the genuine
167 version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
168 the problem. If you cannot, chances are that the problems are specific to
169 Debian GNU/Linux, in which case it should be reported via the Debian Bug
170 Tracking System (use C<reportbug> to report the bug).
172 For other problems that also affect the Debian package, you can and
173 probably should use the Debian BTS, too, because, after all, it's also a
174 bug in the Debian version and it serves as a reminder for other users that
175 might encounter the same issue.
177 =item I am maintaining rxvt-unicode for distribution/OS XXX, any
180 You should build one binary with the default options. F<configure>
181 now enables most useful options, and the trend goes to making them
182 runtime-switchable, too, so there is usually no drawback to enbaling them,
183 except higher disk and possibly memory usage. The perl interpreter should
184 be enabled, as important functionality (menus, selection, likely more in
185 the future) depends on it.
187 You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
188 system-wide (except maybe with C<defaults>). This will result in useful
189 behaviour. If your distribution aims at low memory, add an empty
190 C<perl-ext-common> resource to the app-defaults file. This will keep the
191 perl interpreter disabled until the user enables it.
193 If you can/want build more binaries, I recommend building a minimal
194 one with C<--disable-everything> (very useful) and a maximal one with
195 C<--enable-everything> (less useful, it will be very big due to a lot of
196 encodings built-in that increase download times and are rarely used).
198 =item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
200 It should be, starting with release 7.1. You are encouraged to properly
201 install urxvt with privileges necessary for your OS now.
203 When rxvt-unicode detects that it runs setuid or setgid, it will fork
204 into a helper process for privileged operations (pty handling on some
205 systems, utmp/wtmp/lastlog handling on others) and drop privileges
206 immediately. This is much safer than most other terminals that keep
207 privileges while running (but is more relevant to urxvt, as it contains
208 things as perl interpreters, which might be "helpful" to attackers).
210 This forking is done as the very first within main(), which is very early
211 and reduces possible bugs to initialisation code run before main(), or
212 things like the dynamic loader of your system, which should result in very
215 =item When I log-in to another system it tells me about missing terminfo data?
217 The terminal description used by rxvt-unicode is not as widely available
218 as that for xterm, or even rxvt (for which the same problem often arises).
220 The correct solution for this problem is to install the terminfo, this can
221 be done like this (with ncurses' infocmp):
223 REMOTE=remotesystem.domain
224 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
226 ... or by installing rxvt-unicode normally on the remote system,
228 If you cannot or do not want to do this, then you can simply set
229 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
230 problems arising, which includes wrong keymapping, less and different
231 colours and some refresh errors in fullscreen applications. It's a nice
232 quick-and-dirty workaround for rare cases, though.
234 If you always want to do this (and are fine with the consequences) you
235 can either recompile rxvt-unicode with the desired TERM value or use a
240 If you don't plan to use B<rxvt> (quite common...) you could also replace
241 the rxvt terminfo file with the rxvt-unicode one.
243 =item C<tic> outputs some error when compiling the terminfo entry.
245 Most likely it's the empty definition for C<enacs=>. Just replace it by
246 C<enacs=\E[0@> and try again.
248 =item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
250 =item I need a termcap file entry.
252 One reason you might want this is that some distributions or operating
253 systems still compile some programs using the long-obsoleted termcap
254 library (Fedora Core's bash is one example) and rely on a termcap entry
257 You could use rxvt's termcap entry with resonable results in many cases.
258 You can also create a termcap entry by using terminfo's infocmp program
261 infocmp -C rxvt-unicode
263 Or you could use this termcap entry, generated by the command above:

286 =item Why does C<ls> no longer have coloured output?
288 The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
289 decide wether a terminal has colour, but uses it's own configuration
290 file. Needless to say, C<rxvt-unicode> is not in it's default file (among
291 with most other terminals supporting colour). Either add:
295 to C</etc/DIR_COLORS> or simply add:
297 alias ls='ls --color=auto'
299 to your C<.profile> or C<.bashrc>.
301 =item Why doesn't vim/emacs etc. use the 88 colour mode?
303 =item Why doesn't vim/emacs etc. make use of italic?
305 =item Why are the secondary screen-related options not working properly?
307 Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
308 distributions (most notably Debian GNU/Linux) break rxvt-unicode
309 by setting C<TERM> to C<rxvt>, which doesn't have these extra
310 features. Unfortunately, some of these (most notably, again, Debian
311 GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
312 file, so you will need to install it on your own (See the question B<When
313 I log-in to another system it tells me about missing terminfo data?> on
316 =item My numerical keypad acts weird and generates differing output?
318 Some Debian GNUL/Linux users seem to have this problem, although no
319 specific details were reported so far. It is possible that this is caused
320 by the wrong C<TERM> setting, although the details of wether and how
321 this can happen are unknown, as C<TERM=rxvt> should offer a compatible
322 keymap. See the answer to the previous question, and please report if that
325 =item Rxvt-unicode does not seem to understand the selected encoding?
327 =item Unicode does not seem to work?
329 If you encounter strange problems like typing an accented character but
330 getting two unrelated other characters or similar, or if program output is
331 subtly garbled, then you should check your locale settings.
333 Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
334 programs. Often rxvt-unicode is started in the C<C> locale, while the
335 login script running within the rxvt-unicode window changes the locale to
336 something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
338 The best thing is to fix your startup environment, as you will likely run
339 into other problems. If nothing works you can try this in your .profile.
341 printf '\e]701;%s\007' "$LC_CTYPE"
343 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
344 supported on your systems. Some systems have a C<locale> command which
345 displays this (also, C<perl -e0> can be used to check locale settings, as
346 it will complain loudly if it cannot set the locale). If it displays something
349 locale: Cannot set LC_CTYPE to default locale: ...
351 Then the locale you specified is not supported on your system.
353 If nothing works and you are sure that everything is set correctly then
354 you will need to remember a little known fact: Some programs just don't
357 =item Why do some characters look so much different than others?
359 =item How does rxvt-unicode choose fonts?
361 Most fonts do not contain the full range of Unicode, which is
362 fine. Chances are that the font you (or the admin/package maintainer of
363 your system/os) have specified does not cover all the characters you want
366 B<rxvt-unicode> makes a best-effort try at finding a replacement
367 font. Often the result is fine, but sometimes the chosen font looks
368 bad/ugly/wrong. Some fonts have totally strange characters that don't
369 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
370 intelligence to detect that a specific glyph is wrong: it has to believe
371 the font that the characters it claims to contain indeed look correct.
373 In that case, select a font of your taste and add it to the font list,
376 @@RXVT_NAME@@ -fn basefont,font2,font3...
378 When rxvt-unicode sees a character, it will first look at the base
379 font. If the base font does not contain the character, it will go to the
380 next font, and so on. Specifying your own fonts will also speed up this
381 search and use less resources within rxvt-unicode and the X-server.
383 The only limitation is that none of the fonts may be larger than the base
384 font, as the base font defines the terminal character cell size, which
385 must be the same due to the way terminals work.
387 =item Why do some chinese characters look so different than others?
389 This is because there is a difference between script and language --
390 rxvt-unicode does not know which language the text that is output is,
391 as it only knows the unicode character codes. If rxvt-unicode first
392 sees a japanese/chinese character, it might choose a japanese font for
393 display. Subsequent japanese characters will use that font. Now, many
394 chinese characters aren't represented in japanese fonts, so when the first
395 non-japanese character comes up, rxvt-unicode will look for a chinese font
396 -- unfortunately at this point, it will still use the japanese font for
397 chinese characters that are also in the japanese font.
399 The workaround is easy: just tag a chinese font at the end of your font
400 list (see the previous question). The key is to view the font list as
401 a preference list: If you expect more japanese, list a japanese font
402 first. If you expect more chinese, put a chinese font first.
404 In the future it might be possible to switch language preferences at
405 runtime (the internal data structure has no problem with using different
406 fonts for the same character at the same time, but no interface for this
407 has been designed yet).
409 Until then, you might get away with switching fonts at runtime (see L<Can
410 I switch the fonts at runtime?> later in this document).
412 =item Why does rxvt-unicode sometimes leave pixel droppings?
414 Most fonts were not designed for terminal use, which means that character
415 size varies a lot. A font that is otherwise fine for terminal use might
416 contain some characters that are simply too wide. Rxvt-unicode will avoid
417 these characters. For characters that are just "a bit" too wide a special
418 "careful" rendering mode is used that redraws adjacent characters.
420 All of this requires that fonts do not lie about character sizes,
421 however: Xft fonts often draw glyphs larger than their acclaimed bounding
422 box, and rxvt-unicode has no way of detecting this (the correct way is to
423 ask for the character bounding box, which unfortunately is wrong in these
426 It's not clear (to me at least), wether this is a bug in Xft, freetype,
427 or the respective font. If you encounter this problem you might try using
428 the C<-lsp> option to give the font more height. If that doesn't work, you
429 might be forced to use a different font.
431 All of this is not a problem when using X11 core fonts, as their bounding
434 =item On Solaris 9, many line-drawing characters are too wide.
436 Seems to be a known bug, read
437 L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
438 following ugly workaround to get non-double-wide-characters working:
440 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
442 =item My Compose (Multi_key) key is no longer working.
444 The most common causes for this are that either your locale is not set
445 correctly, or you specified a B<preeditStyle> that is not supported by
446 your input method. For example, if you specified B<OverTheSpot> and
447 your input method (e.g. the default input method handling Compose keys)
448 does not support this (for instance because it is not visual), then
449 rxvt-unicode will continue without an input method.
451 In this case either do not specify a B<preeditStyle> or specify more than
452 one pre-edit style, such as B<OverTheSpot,Root,None>.
454 =item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
456 Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
457 international keyboards) or simply use ISO 14755 support to your
458 advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
459 codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
462 =item How can I keep rxvt-unicode from using reverse video so much?
464 First of all, make sure you are running with the right terminal settings
465 (C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
466 make sure you have specified colours for italic and bold, as otherwise
467 rxvt-unicode might use reverse video to simulate the effect:
472 =item Some programs assume totally weird colours (red instead of blue), how can I fix that?
474 For some unexplainable reason, some rare programs assume a very weird
475 colour palette when confronted with a terminal with more than the standard
476 8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
477 these programs not to assume non-ISO colours without very good reasons.
479 In the meantime, you can either edit your C<rxvt-unicode> terminfo
480 definition to only claim 8 colour support or use C<TERM=rxvt>, which will
481 fix colours but keep you from using other rxvt-unicode features.
483 =item I am on FreeBSD and rxvt-unicode does not seem to work at all.
485 Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
486 in your compile environment, or an implementation that implements it,
487 wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
488 B<wchar_t> is represented as unicode.
490 As you might have guessed, FreeBSD does neither define this symobl nor
491 does it support it. Instead, it uses it's own internal representation of
492 B<wchar_t>. This is, of course, completely fine with respect to standards.
494 However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
495 C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
497 C<__STDC_ISO_10646__> is the only sane way to support multi-language
498 apps in an OS, as using a locale-dependent (and non-standardized)
499 representation of B<wchar_t> makes it impossible to convert between
500 B<wchar_t> (as used by X11 and your applications) and any other encoding
501 without implementing OS-specific-wrappers for each and every locale. There
502 simply are no APIs to convert B<wchar_t> into anything except the current
505 Some applications (such as the formidable B<mlterm>) work around this
506 by carrying their own replacement functions for character set handling
507 with them, and either implementing OS-dependent hacks or doing multiple
508 conversions (which is slow and unreliable in case the OS implements
509 encodings slightly different than the terminal emulator).
511 The rxvt-unicode author insists that the right way to fix this is in the
512 system libraries once and for all, instead of forcing every app to carry
513 complete replacements for them :)
515 =item I use Solaris 9 and it doesn't compile/work/etc.
517 Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
518 problems with C<wcwidth> and a compile problem.
520 =item How can I use rxvt-unicode under cygwin?
522 rxvt-unicode should compile and run out of the box on cygwin, using
523 the X11 libraries that come with cygwin. libW11 emulation is no
524 longer supported (and makes no sense, either, as it only supported a
525 single font). I recommend starting the X-server in C<-multiwindow> or
526 C<-rootless> mode instead, which will result in similar look&feel as the
527 old libW11 emulation.
529 At the time of this writing, cygwin didn't seem to support any multi-byte
530 encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
533 =item How does rxvt-unicode determine the encoding to use?
535 =item Is there an option to switch encodings?
537 Unlike some other terminals, rxvt-unicode has no encoding switch, and no
538 specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
539 UTF-8 or any other encodings with respect to terminal I/O.
541 The reasons is that there exists a perfectly fine mechanism for selecting
542 the encoding, doing I/O and (most important) communicating this to all
543 applications so everybody agrees on character properties such as width
544 and code number. This mechanism is the I<locale>. Applications not using
545 that info will have problems (for example, C<xterm> gets the width of
546 characters wrong as it uses it's own, locale-independent table under all
549 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
550 programs doing the same (that is, most) will automatically agree in the
551 interpretation of characters.
553 Unfortunately, there is no system-independent way to select locales, nor
554 is there a standard on how locale specifiers will look like.
556 On most systems, the content of the C<LC_CTYPE> environment variable
557 contains an arbitrary string which corresponds to an already-installed
558 locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
559 C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
560 (i.e. C<de> or C<german>) are also common.
562 Rxvt-unicode ignores all other locale categories, and except for
563 the encoding, ignores country or language-specific settings,
564 i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
567 If you want to use a specific encoding you have to make sure you start
568 rxvt-unicode with the correct C<LC_CTYPE> category.
570 =item Can I switch locales at runtime?
572 Yes, using an escape sequence. Try something like this, which sets
573 rxvt-unicode's idea of C<LC_CTYPE>.
575 printf '\e]701;%s\007' ja_JP.SJIS
577 See also the previous answer.
579 Sometimes this capability is rather handy when you want to work in
580 one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
581 (e.g. UTF-8). For example, I use this script to start C<xjdic>, which
582 first switches to a locale supported by xjdic and back later:
584 printf '\e]701;%s\007' ja_JP.SJIS
586 printf '\e]701;%s\007' de_DE.UTF-8
588 You can also use xterm's C<luit> program, which usually works fine, except
589 for some locales where character width differs between program- and
590 rxvt-unicode-locales.
592 =item Can I switch the fonts at runtime?
594 Yes, using an escape sequence. Try something like this, which has the same
595 effect as using the C<-fn> switch, and takes effect immediately:
597 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
599 This is useful if you e.g. work primarily with japanese (and prefer a
600 japanese font), but you have to switch to chinese temporarily, where
601 japanese fonts would only be in your way.
603 You can think of this as a kind of manual ISO-2022 switching.
605 =item Why do italic characters look as if clipped?
607 Many fonts have difficulties with italic characters and hinting. For
608 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
609 Mono> completely fails in it's italic face. A workaround might be to
610 enable freetype autohinting, i.e. like this:
612 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
613 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
615 =item My input method wants <some encoding> but I want UTF-8, what can I do?
617 You can specify separate locales for the input method and the rest of the
618 terminal, using the resource C<imlocale>:
620 URxvt.imlocale: ja_JP.EUC-JP
622 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
623 use your input method. Please note, however, that you will not be able to
624 input characters outside C<EUC-JP> in a normal way then, as your input
627 =item Rxvt-unicode crashes when the X Input Method changes or exits.
629 Unfortunately, this is unavoidable, as the XIM protocol is racy by
630 design. Applications can avoid some crashes at the expense of memory
631 leaks, and Input Methods can avoid some crashes by careful ordering at
632 exit time. B<kinput2> (and derived input methods) generally succeeds,
633 while B<SCIM> (or similar input methods) fails. In the end, however,
634 crashes cannot be completely avoided even if both sides cooperate.
636 So the only workaround is not to kill your Input Method Servers.
638 =item Rxvt-unicode uses gobs of memory, how can I reduce that?
640 Rxvt-unicode tries to obey the rule of not charging you for something you
641 don't use. One thing you should try is to configure out all settings that
642 you don't need, for example, Xft support is a resource hog by design,
643 when used. Compiling it out ensures that no Xft font will be loaded
644 accidentally when rxvt-unicode tries to find a font for your characters.
646 Also, many people (me included) like large windows and even larger
647 scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
648 6 bytes per screen cell. For a 160x?? window this amounts to almost a
649 kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
650 use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
651 rxvt-unicode then uses 8 bytes per screen cell.
653 =item Can I speed up Xft rendering somehow?
655 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
656 it is simply slow. If you still want Xft fonts you might try to disable
657 antialiasing (by appending C<:antialias=false>), which saves lots of
658 memory and also speeds up rendering considerably.
660 =item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
662 Rxvt-unicode will use whatever you specify as a font. If it needs to
663 fall back to it's default font search list it will prefer X11 core
664 fonts, because they are small and fast, and then use Xft fonts. It has
665 antialiasing disabled for most of them, because the author thinks they
668 If you want antialiasing, you have to specify the fonts manually.
670 =item Mouse cut/paste suddenly no longer works.
672 Make sure that mouse reporting is actually turned off since killing
673 some editors prematurely may leave the mouse in mouse report mode. I've
674 heard that tcsh may use mouse reporting unless it otherwise specified. A
675 quick check is to see if cut/paste works when the Alt or Shift keys are
678 =item What's with this bold/blink stuff?
680 If no bold colour is set via C<colorBD:>, bold will invert text using the
681 standard foreground colour.
683 For the standard background colour, blinking will actually make the
684 text blink when compiled with C<--enable-blinking>. with standard
685 colours. Without C<--enable-blinking>, the blink attribute will be
688 On ANSI colours, bold/blink attributes are used to set high-intensity
689 foreground/background colors.
691 color0-7 are the low-intensity colors.
693 color8-15 are the corresponding high-intensity colors.
695 =item I don't like the screen colors. How do I change them?
697 You can change the screen colors at run-time using F<~/.Xdefaults>
698 resources (or as long-options).
700 Here are values that are supposed to resemble a VGA screen,
701 including the murky brown that passes for low-intensity yellow:
703 URxvt.color0: #000000
704 URxvt.color1: #A80000
705 URxvt.color2: #00A800
706 URxvt.color3: #A8A800
707 URxvt.color4: #0000A8
708 URxvt.color5: #A800A8
709 URxvt.color6: #00A8A8
710 URxvt.color7: #A8A8A8
712 URxvt.color8: #000054

717 URxvt.color13: #FF00FF
718 URxvt.color14: #00FFFF
719 URxvt.color15: #FFFFFF
721 And here is a more complete set of non-standard colors described (not by
722 me) as "pretty girly".
724 URxvt.cursorColor: #dc74d1
725 URxvt.pointerColor: #dc74d1

743 =item How can I start @@RXVT_NAME@@d in a race-free way?
745 Try C<@@RXVT_NAME@@d -f -o>, which tells @@RXVT_NAME@@d to open the
746 display, create the listening socket and then fork.
748 =item What's with the strange Backspace/Delete key behaviour?
750 Assuming that the physical Backspace key corresponds to the
751 BackSpace keysym (not likely for Linux ... see the following
752 question) there are two standard values that can be used for
753 Backspace: C<^H> and C<^?>.
755 Historically, either value is correct, but rxvt-unicode adopts the debian
756 policy of using C<^?> when unsure, because it's the one only only correct
759 Rxvt-unicode tries to inherit the current stty settings and uses the value
760 of `erase' to guess the value for backspace. If rxvt-unicode wasn't
761 started from a terminal (say, from a menu or by remote shell), then the
762 system value of `erase', which corresponds to CERASE in <termios.h>, will
763 be used (which may not be the same as your stty setting).
765 For starting a new rxvt-unicode:
775 Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
777 For an existing rxvt-unicode:
787 This helps satisfy some of the Backspace discrepancies that occur, but
788 if you use Backspace = C<^H>, make sure that the termcap/terminfo value
789 properly reflects that.
791 The Delete key is a another casualty of the ill-defined Backspace problem.
792 To avoid confusion between the Backspace and Delete keys, the Delete
793 key has been assigned an escape sequence to match the vt100 for Execute
794 (C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
796 Some other Backspace problems:
798 some editors use termcap/terminfo,
799 some editors (vim I'm told) expect Backspace = ^H,
800 GNU Emacs (and Emacs-like editors) use ^H for help.
802 Perhaps someday this will all be resolved in a consistent manner.
804 =item I don't like the key-bindings. How do I change them?
806 There are some compile-time selections available via configure. Unless
807 you have run "configure" with the C<--disable-resources> option you can
808 use the `keysym' resource to alter the keystrings associated with keysyms.
810 Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>

835 =item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
836 How do I make use of them? For example, the Sun Keyboard type 4
837 has the following mappings that rxvt-unicode doesn't recognize.
846 Rather than have rxvt-unicode try to accommodate all the various possible
847 keyboard mappings, it is better to use `xmodmap' to remap the keys as
848 required for your particular machine.
850 =item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
851 I need this to decide about setting colors etc.

854 check and see if that is set. Note that several programs, JED, slrn,
855 Midnight Commander automatically check this variable to decide whether or
858 =item How do I set the correct, full IP address for the DISPLAY variable?
860 If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
861 insecure mode then it is possible to use the following shell script
862 snippets to correctly set the display. If your version of rxvt-unicode
863 wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
864 the COLORTERM variable can be used to distinguish rxvt-unicode from a

1888 =head1 CONFIGURE OPTIONS
1890 General hint: if you get compile errors, then likely your configuration
1891 hasn't been tested well. Either try with C<--enable-everything> or use
1892 the F<./reconf> script as a base for experiments. F<./reconf> is used by
1893 myself, so it should generally be a working config. Of course, you should
1894 always report when a combination doesn't work, so it can be fixed. Marc
1895 Lehmann <rxvt@schmorp.de>.
1901 =item --enable-everything
1903 Add (or remove) support for all non-multichoice options listed in "./configure
1906 You can specify this and then disable options you do not like by
1907 I<following> this with the appropriate C<--disable-...> arguments,
1908 or you can start with a minimal configuration by specifying
1909 C<--disable-everything> and than adding just the C<--enable-...> arguments
1912 =item --enable-xft (default: enabled)
1914 Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
1915 slower and require lots of memory, but as long as you don't use them, you
1918 =item --enable-font-styles (default: on)
1920 Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
1921 styles. The fonts can be set manually or automatically.
1923 =item --with-codesets=NAME,... (default: all)
1925 Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
1926 are always compiled in, which includes most 8-bit character sets). These
1927 codeset tables are used for driving X11 core fonts, they are not required
1928 for Xft fonts, although having them compiled in lets rxvt-unicode choose
1929 replacement fonts more intelligently. Compiling them in will make your
1930 binary bigger (all of together cost about 700kB), but it doesn't increase
1931 memory usage unless you use a font requiring one of these encodings.
1935 all all available codeset groups
1936 zh common chinese encodings
1937 zh_ext rarely used but very big chinese encodigs
1938 jp common japanese encodings
1939 jp_ext rarely used but big japanese encodings
1944 =item --enable-xim (default: on)
1946 Add support for XIM (X Input Method) protocol. This allows using
1947 alternative input methods (e.g. kinput2) and will also correctly
1948 set up the input for people using dead keys or compose keys.
1950 =item --enable-unicode3 (default: off)
1952 Recommended to stay off unless you really need non-BMP characters.
1954 Enable direct support for displaying unicode codepoints above
1955 65535 (the basic multilingual page). This increases storage
1956 requirements per character from 2 to 4 bytes. X11 fonts do not yet
1957 support these extra characters, but Xft does.
1959 Please note that rxvt-unicode can store unicode code points >65535
1960 even without this flag, but the number of such characters is
1961 limited to a view thousand (shared with combining characters,
1962 see next switch), and right now rxvt-unicode cannot display them
1963 (input/output and cut&paste still work, though).
1965 =item --enable-combining (default: on)
1967 Enable automatic composition of combining characters into
1968 composite characters. This is required for proper viewing of text
1969 where accents are encoded as seperate unicode characters. This is
1970 done by using precomposited characters when available or creating
1971 new pseudo-characters when no precomposed form exists.
1973 Without --enable-unicode3, the number of additional precomposed
1974 characters is somewhat limited (the 6400 private use characters will be
1975 (ab-)used). With --enable-unicode3, no practical limit exists.
1977 This option will also enable storage (but not display) of characters
1978 beyond plane 0 (>65535) when --enable-unicode3 was not specified.
1980 The combining table also contains entries for arabic presentation forms,
1981 but these are not currently used. Bug me if you want these to be used (and
1982 tell me how these are to be used...).
1984 =item --enable-fallback(=CLASS) (default: Rxvt)
1986 When reading resource settings, also read settings for class CLASS. To
1987 disable resource fallback use --disable-fallback.
1989 =item --with-res-name=NAME (default: urxvt)
1991 Use the given name as default application name when
1992 reading resources. Specify --with-res-name=rxvt to replace rxvt.
1994 =item --with-res-class=CLASS /default: URxvt)
1996 Use the given class as default application class
1997 when reading resources. Specify --with-res-class=Rxvt to replace
2000 =item --enable-utmp (default: on)
2002 Write user and tty to utmp file (used by programs like F<w>) at
2003 start of rxvt execution and delete information when rxvt exits.
2005 =item --enable-wtmp (default: on)
2007 Write user and tty to wtmp file (used by programs like F<last>) at
2008 start of rxvt execution and write logout when rxvt exits. This
2009 option requires --enable-utmp to also be specified.
2011 =item --enable-lastlog (default: on)
2013 Write user and tty to lastlog file (used by programs like
2014 F<lastlogin>) at start of rxvt execution. This option requires
2015 --enable-utmp to also be specified.
2017 =item --enable-xpm-background (default: on)
2019 Add support for XPM background pixmaps.
2021 =item --enable-transparency (default: on)
2023 Add support for inheriting parent backgrounds thus giving a fake
2024 transparency to the term.
2026 =item --enable-fading (default: on)
2028 Add support for fading the text when focus is lost (requires C<--enable-transparency>).
2030 =item --enable-tinting (default: on)
2032 Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
2034 =item --enable-rxvt-scroll (default: on)
2036 Add support for the original rxvt scrollbar.
2038 =item --enable-next-scroll (default: on)
2040 Add support for a NeXT-like scrollbar.
2042 =item --enable-xterm-scroll (default: on)
2044 Add support for an Xterm-like scrollbar.
2046 =item --enable-plain-scroll (default: on)
2048 Add support for a very unobtrusive, plain-looking scrollbar that
2049 is the favourite of the rxvt-unicode author, having used it for
2052 =item --enable-ttygid (default: off)
2054 Change tty device setting to group "tty" - only use this if
2055 your system uses this type of security.
2057 =item --disable-backspace-key
2059 Removes any handling of the backspace key by us - let the X server do it.
2061 =item --disable-delete-key
2063 Removes any handling of the delete key by us - let the X server
2066 =item --disable-resources
2068 Removes any support for resource checking.
2070 =item --disable-swapscreen
2072 Remove support for secondary/swap screen.
2074 =item --enable-frills (default: on)
2076 Add support for many small features that are not essential but nice to
2077 have. Normally you want this, but for very small binaries you may want to
2080 A non-exhaustive list of features enabled by C<--enable-frills> (possibly
2081 in combination with other switches) is:
2084 EWMH-hints (pid, utf8 names) and protocols (ping)
2085 seperate underline colour (-underlineColor)
2086 settable border widths and borderless switch (-w, -b, -bl)

2098 hold on exit (-hold)
2099 skip builtin block graphics (-sbg)
2100 sgr modes 90..97 and 100..107
2102 =item --enable-iso14755 (default: on)
2104 Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
2105 F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
2106 C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
2109 =item --enable-keepscrolling (default: on)
2111 Add support for continual scrolling of the display when you hold
2112 the mouse button down on a scrollbar arrow.
2114 =item --enable-mousewheel (default: on)
2116 Add support for scrolling via mouse wheel or buttons 4 & 5.
2118 =item --enable-slipwheeling (default: on)
2120 Add support for continual scrolling (using the mouse wheel as an
2121 accelerator) while the control key is held down. This option
2122 requires --enable-mousewheel to also be specified.
2124 =item --disable-new-selection
2126 Remove support for mouse selection style like that of xterm.
2128 =item --enable-dmalloc (default: off)
2130 Use Gray Watson's malloc - which is good for debugging See
2131 http://www.letters.com/dmalloc/ for details If you use either this or the
2132 next option, you may need to edit src/Makefile after compiling to point
2133 DINCLUDE and DLIB to the right places.
2135 You can only use either this option and the following (should
2138 =item --enable-dlmalloc (default: off)
2140 Use Doug Lea's malloc - which is good for a production version
2141 See L<http://g.oswego.edu/dl/html/malloc.html> for details.
2143 =item --enable-smart-resize (default: on)
2145 Add smart growth/shrink behaviour when changing font size via hot
2146 keys. This should keep the window corner which is closest to a corner of
2147 the screen in a fixed position.
2149 =item --enable-pointer-blank (default: on)
2151 Add support to have the pointer disappear when typing or inactive.
2153 =item --enable-perl (default: on)
2155 Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
2156 manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the files
2157 in F<src/perl-ext/> for the extensions that are installed by default. The
2158 perl interpreter that is used can be specified via the C<PERL> environment
2159 variable when running configure.
2161 =item --with-name=NAME (default: urxvt)
2163 Set the basename for the installed binaries, resulting
2164 in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
2167 =item --with-term=NAME (default: rxvt-unicode)
2169 Change the environmental variable for the terminal to NAME.
2171 =item --with-terminfo=PATH
2173 Change the environmental variable for the path to the terminfo tree to
2178 Use the X Window System (pretty much default, eh?).
2180 =item --with-xpm-includes=DIR
2182 Look for the XPM includes in DIR.
2184 =item --with-xpm-library=DIR
2186 Look for the XPM library in DIR.
2190 Not needed - define via --enable-xpm-background.
