29 If you want to select e.g. alphanumeric words, you can use the following
32 URxvt.selection.pattern-0: ([[:word:]]+)
34 If you click more than twice, the selection will be extended
37 To get a selection that is very similar to the old code, try this pattern:
39 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)

42 selects words like the old code.

47 You can disable the perl extension completely by setting the
48 B<perl-ext-common> resource to the empty string, which also keeps
49 rxvt-unicode from initialising perl, saving memory.
51 If you only want to disable specific features, you first have to
52 identify which perl extension is responsible. For this, read the section
53 B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
54 example, to disable the B<selection-popup> and B<option-popup>, specify
55 this B<perl-ext-common> resource:
57 URxvt.perl-ext-common: default,-selection-popup,-option-popup
59 This will keep the default extensions, but disable the two popup
60 extensions. Some extensions can also be configured, for example,
61 scrollback search mode is triggered by B<M-s>. You can move it to any
62 other combination either by setting the B<searchable-scrollback> resource:
64 URxvt.searchable-scrollback: CM-s
66 =head3 The cursor moves when selecting text in the current input line, how
71 =head2 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor
72 outputs strange escape sequences, how do I fix this?
74 These are caused by the C<readline> perl extension. Under normal
75 circumstances, it will move your cursor around when you click into the
76 line that contains it. It tries hard not to do this at the wrong moment,
77 but when running a program that doesn't parse cursor movements or in some
78 cases during rlogin sessions, it fails to detect this properly.
80 You can permamently switch this feature off by disabling the C<readline>
83 URxvt.perl-ext-common: default,-readline
85 =head2 Why doesn't rxvt-unicode read my resources?
87 Well, why, indeed? It does, in a way very similar to other X
88 applications. Most importantly, this means that if you or your OS loads
89 resources into the X display (the right way to do it), rxvt-unicode will
90 ignore any resource files in your home directory. It will only read
91 F<$HOME/.Xdefaults> when no resources are attached to the display.
93 If you have or use an F<$HOME/.Xresources> file, chances are that
94 resources are loaded into your X-server. In this case, you have to
95 re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
97 Also consider the form resources have to use:
101 If you want to use another form (there are lots of different ways of
102 specifying resources), make sure you understand wether and why it
103 works. If unsure, use the form above.
105 =head2 I can't get transparency working, what am I doing wrong?
107 First of all, transparency isn't officially supported in rxvt-unicode, so
108 you are mostly on your own. Do not bug the author about it (but you may
109 bug everybody else). Also, if you can't get it working consider it a rite
110 of passage: ... and you failed.
112 Here are four ways to get transparency. B<Do> read the manpage and option
113 descriptions for the programs mentioned and rxvt-unicode. Really, do it!
115 1. Use inheritPixmap:
117 Esetroot wallpaper.jpg
118 @@RXVT_NAME@@ -ip -tint red -sh 40
120 That works. If you think it doesn't, you lack transparency and tinting
121 support, or you are unable to read.
123 2. Use a simple pixmap and emulate pseudo-transparency. This enables you
124 to use effects other than tinting and shading: Just shade/tint/whatever
125 your picture with gimp:
127 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
128 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
130 That works. If you think it doesn't, you lack XPM and Perl support, or you
133 3. Use an ARGB visual:
135 @@RXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
137 This requires XFT support, and the support of your X-server. If that
138 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
139 there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
140 bugfixes and workarounds for Xft and Xlib to make it work, but that
141 doesn't mean that your WM has the required kludges in place.
143 4. Use xcompmgr and let it do the job:
145 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
146 -set _NET_WM_WINDOW_OPACITY 0xc0000000
148 Then click on a window you want to make transparent. Replace C<0xc0000000>
149 by other values to change the degree of opacity. If it doesn't work and
150 your server crashes, you got to keep the pieces.
152 =head2 Isn't rxvt supposed to be small? Don't all those features bloat?
154 I often get asked about this, and I think, no, they didn't cause extra
155 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
156 that the urxvt binary is larger (due to some encoding tables always being
157 compiled in), but it actually uses less memory (RSS) after startup. Even
158 with C<--disable-everything>, this comparison is a bit unfair, as many
159 features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
160 already in use in this mode.
162 text data bss drs rss filename
163 98398 1664 24 15695 1824 rxvt --disable-everything
164 188985 9048 66616 18222 1788 urxvt --disable-everything
166 When you C<--enable-everything> (which _is_ unfair, as this involves xft
167 and full locale/XIM support which are quite bloaty inside libX11 and my
168 libc), the two diverge, but not unreasnobaly so.
170 text data bss drs rss filename
171 163431 2152 24 20123 2060 rxvt --enable-everything
172 1035683 49680 66648 29096 3680 urxvt --enable-everything
174 The very large size of the text section is explained by the east-asian
175 encoding tables, which, if unused, take up disk space but nothing else
176 and can be compiled out unless you rely on X11 core fonts that use those
177 encodings. The BSS size comes from the 64k emergency buffer that my c++
178 compiler allocates (but of course doesn't use unless you are out of
179 memory). Also, using an xft font instead of a core font immediately adds a
180 few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
183 Of course, due to every character using two or four bytes instead of one,
184 a large scrollback buffer will ultimately make rxvt-unicode use more
187 Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
188 still fares rather well. And compared to some monsters like gnome-terminal
189 (21152k + extra 4204k in separate processes) or konsole (22200k + extra
190 43180k in daemons that stay around after exit, plus half a minute of
191 startup time, including the hundreds of warnings it spits out), it fares
194 =head2 Why C++, isn't that unportable/bloated/uncool?
196 Is this a question? :) It comes up very often. The simple answer is: I had
197 to write it, and C++ allowed me to write and maintain it in a fraction
198 of the time and effort (which is a scarce resource for me). Put even
199 shorter: It simply wouldn't exist without C++.
201 My personal stance on this is that C++ is less portable than C, but in
202 the case of rxvt-unicode this hardly matters, as its portability limits
203 are defined by things like X11, pseudo terminals, locale support and unix
204 domain sockets, which are all less portable than C++ itself.
206 Regarding the bloat, see the above question: It's easy to write programs
207 in C that use gobs of memory, an certainly possible to write programs in
208 C++ that don't. C++ also often comes with large libraries, but this is
209 not necessarily the case with GCC. Here is what rxvt links against on my
210 system with a minimal config:
212 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
213 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
214 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
215 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
217 And here is rxvt-unicode:
219 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
220 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
221 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
222 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
223 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
225 No large bloated libraries (of course, none were linked in statically),
226 except maybe libX11 :)
228 =head2 Does it support tabs, can I have a tabbed rxvt-unicode?
230 Beginning with version 7.3, there is a perl extension that implements a
231 simple tabbed terminal. It is installed by default, so any of these should
234 @@RXVT_NAME@@ -pe tabbed
236 URxvt.perl-ext-common: default,tabbed
238 It will also work fine with tabbing functionality of many window managers
239 or similar tabbing programs, and its embedding-features allow it to be
240 embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
241 the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
242 (murxvt) terminal as an example embedding application.
244 =head2 How do I know which rxvt-unicode version I'm using?
246 The version number is displayed with the usage (-h). Also the escape
247 sequence C<ESC [ 8 n> sets the window title to the version number. When
248 using the @@RXVT_NAME@@c client, the version displayed is that of the
251 =head2 I am using Debian GNU/Linux and have a problem...
253 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
254 patches that considerably change the behaviour of rxvt-unicode (but
255 unfortunately this notice has been removed). Before reporting a bug to
256 the original rxvt-unicode author please download and install the genuine
257 version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
258 the problem. If you cannot, chances are that the problems are specific to
259 Debian GNU/Linux, in which case it should be reported via the Debian Bug
260 Tracking System (use C<reportbug> to report the bug).
262 For other problems that also affect the Debian package, you can and
263 probably should use the Debian BTS, too, because, after all, it's also a
264 bug in the Debian version and it serves as a reminder for other users that
265 might encounter the same issue.
267 =head2 I am maintaining rxvt-unicode for distribution/OS XXX, any
270 You should build one binary with the default options. F<configure>
271 now enables most useful options, and the trend goes to making them
272 runtime-switchable, too, so there is usually no drawback to enbaling them,
273 except higher disk and possibly memory usage. The perl interpreter should
274 be enabled, as important functionality (menus, selection, likely more in
275 the future) depends on it.
277 You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
278 system-wide (except maybe with C<defaults>). This will result in useful
279 behaviour. If your distribution aims at low memory, add an empty
280 C<perl-ext-common> resource to the app-defaults file. This will keep the
281 perl interpreter disabled until the user enables it.
283 If you can/want build more binaries, I recommend building a minimal
284 one with C<--disable-everything> (very useful) and a maximal one with
285 C<--enable-everything> (less useful, it will be very big due to a lot of
286 encodings built-in that increase download times and are rarely used).
288 =head2 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
290 It should be, starting with release 7.1. You are encouraged to properly
291 install urxvt with privileges necessary for your OS now.
293 When rxvt-unicode detects that it runs setuid or setgid, it will fork
294 into a helper process for privileged operations (pty handling on some
295 systems, utmp/wtmp/lastlog handling on others) and drop privileges
296 immediately. This is much safer than most other terminals that keep
297 privileges while running (but is more relevant to urxvt, as it contains
298 things as perl interpreters, which might be "helpful" to attackers).
300 This forking is done as the very first within main(), which is very early
301 and reduces possible bugs to initialisation code run before main(), or
302 things like the dynamic loader of your system, which should result in very
305 =head2 When I log-in to another system it tells me about missing terminfo data?
307 The terminal description used by rxvt-unicode is not as widely available
308 as that for xterm, or even rxvt (for which the same problem often arises).
310 The correct solution for this problem is to install the terminfo, this can
311 be done like this (with ncurses' infocmp):
313 REMOTE=remotesystem.domain
314 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
316 ... or by installing rxvt-unicode normally on the remote system,
318 If you cannot or do not want to do this, then you can simply set
319 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
320 problems arising, which includes wrong keymapping, less and different
321 colours and some refresh errors in fullscreen applications. It's a nice
322 quick-and-dirty workaround for rare cases, though.
324 If you always want to do this (and are fine with the consequences) you
325 can either recompile rxvt-unicode with the desired TERM value or use a
330 If you don't plan to use B<rxvt> (quite common...) you could also replace
331 the rxvt terminfo file with the rxvt-unicode one.
333 =head2 C<tic> outputs some error when compiling the terminfo entry.
335 Most likely it's the empty definition for C<enacs=>. Just replace it by
336 C<enacs=\E[0@> and try again.
338 =head2 C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
342 =head2 I need a termcap file entry.
344 One reason you might want this is that some distributions or operating
345 systems still compile some programs using the long-obsoleted termcap
346 library (Fedora Core's bash is one example) and rely on a termcap entry
349 You could use rxvt's termcap entry with resonable results in many cases.
350 You can also create a termcap entry by using terminfo's infocmp program
353 infocmp -C rxvt-unicode
355 Or you could use this termcap entry, generated by the command above:

378 =head2 Why does C<ls> no longer have coloured output?
380 The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
381 decide wether a terminal has colour, but uses it's own configuration
382 file. Needless to say, C<rxvt-unicode> is not in it's default file (among
383 with most other terminals supporting colour). Either add:
387 to C</etc/DIR_COLORS> or simply add:
389 alias ls='ls --color=auto'
391 to your C<.profile> or C<.bashrc>.
393 =head2 Why doesn't vim/emacs etc. use the 88 colour mode?
397 =head2 Why doesn't vim/emacs etc. make use of italic?
401 =head2 Why are the secondary screen-related options not working properly?
403 Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
404 distributions (most notably Debian GNU/Linux) break rxvt-unicode
405 by setting C<TERM> to C<rxvt>, which doesn't have these extra
406 features. Unfortunately, some of these (most notably, again, Debian
407 GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
408 file, so you will need to install it on your own (See the question B<When
409 I log-in to another system it tells me about missing terminfo data?> on
412 =head2 My numerical keypad acts weird and generates differing output?
414 Some Debian GNUL/Linux users seem to have this problem, although no
415 specific details were reported so far. It is possible that this is caused
416 by the wrong C<TERM> setting, although the details of wether and how
417 this can happen are unknown, as C<TERM=rxvt> should offer a compatible
418 keymap. See the answer to the previous question, and please report if that
421 =head2 Rxvt-unicode does not seem to understand the selected encoding?
425 =head2 Unicode does not seem to work?
427 If you encounter strange problems like typing an accented character but
428 getting two unrelated other characters or similar, or if program output is
429 subtly garbled, then you should check your locale settings.
431 Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
432 programs. Often rxvt-unicode is started in the C<C> locale, while the
433 login script running within the rxvt-unicode window changes the locale to
434 something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
436 The best thing is to fix your startup environment, as you will likely run
437 into other problems. If nothing works you can try this in your .profile.
439 printf '\e]701;%s\007' "$LC_CTYPE"
441 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
442 supported on your systems. Some systems have a C<locale> command which
443 displays this (also, C<perl -e0> can be used to check locale settings, as
444 it will complain loudly if it cannot set the locale). If it displays something
447 locale: Cannot set LC_CTYPE to default locale: ...
449 Then the locale you specified is not supported on your system.
451 If nothing works and you are sure that everything is set correctly then
452 you will need to remember a little known fact: Some programs just don't
455 =head2 Why do some characters look so much different than others?
459 =head2 How does rxvt-unicode choose fonts?
461 Most fonts do not contain the full range of Unicode, which is
462 fine. Chances are that the font you (or the admin/package maintainer of
463 your system/os) have specified does not cover all the characters you want
466 B<rxvt-unicode> makes a best-effort try at finding a replacement
467 font. Often the result is fine, but sometimes the chosen font looks
468 bad/ugly/wrong. Some fonts have totally strange characters that don't
469 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
470 intelligence to detect that a specific glyph is wrong: it has to believe
471 the font that the characters it claims to contain indeed look correct.
473 In that case, select a font of your taste and add it to the font list,
476 @@RXVT_NAME@@ -fn basefont,font2,font3...
478 When rxvt-unicode sees a character, it will first look at the base
479 font. If the base font does not contain the character, it will go to the
480 next font, and so on. Specifying your own fonts will also speed up this
481 search and use less resources within rxvt-unicode and the X-server.
483 The only limitation is that none of the fonts may be larger than the base
484 font, as the base font defines the terminal character cell size, which
485 must be the same due to the way terminals work.
487 =head2 Why do some chinese characters look so different than others?
489 This is because there is a difference between script and language --
490 rxvt-unicode does not know which language the text that is output is,
491 as it only knows the unicode character codes. If rxvt-unicode first
492 sees a japanese/chinese character, it might choose a japanese font for
493 display. Subsequent japanese characters will use that font. Now, many
494 chinese characters aren't represented in japanese fonts, so when the first
495 non-japanese character comes up, rxvt-unicode will look for a chinese font
496 -- unfortunately at this point, it will still use the japanese font for
497 chinese characters that are also in the japanese font.
499 The workaround is easy: just tag a chinese font at the end of your font
500 list (see the previous question). The key is to view the font list as
501 a preference list: If you expect more japanese, list a japanese font
502 first. If you expect more chinese, put a chinese font first.
504 In the future it might be possible to switch language preferences at
505 runtime (the internal data structure has no problem with using different
506 fonts for the same character at the same time, but no interface for this
507 has been designed yet).
509 Until then, you might get away with switching fonts at runtime (see L<Can
510 I switch the fonts at runtime?> later in this document).
512 =head2 Why does rxvt-unicode sometimes leave pixel droppings?
514 Most fonts were not designed for terminal use, which means that character
515 size varies a lot. A font that is otherwise fine for terminal use might
516 contain some characters that are simply too wide. Rxvt-unicode will avoid
517 these characters. For characters that are just "a bit" too wide a special
518 "careful" rendering mode is used that redraws adjacent characters.
520 All of this requires that fonts do not lie about character sizes,
521 however: Xft fonts often draw glyphs larger than their acclaimed bounding
522 box, and rxvt-unicode has no way of detecting this (the correct way is to
523 ask for the character bounding box, which unfortunately is wrong in these
526 It's not clear (to me at least), wether this is a bug in Xft, freetype,
527 or the respective font. If you encounter this problem you might try using
528 the C<-lsp> option to give the font more height. If that doesn't work, you
529 might be forced to use a different font.
531 All of this is not a problem when using X11 core fonts, as their bounding
534 =head2 On Solaris 9, many line-drawing characters are too wide.
536 Seems to be a known bug, read
537 L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
538 following ugly workaround to get non-double-wide-characters working:
540 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
542 =head2 My Compose (Multi_key) key is no longer working.
544 The most common causes for this are that either your locale is not set
545 correctly, or you specified a B<preeditStyle> that is not supported by
546 your input method. For example, if you specified B<OverTheSpot> and
547 your input method (e.g. the default input method handling Compose keys)
548 does not support this (for instance because it is not visual), then
549 rxvt-unicode will continue without an input method.
551 In this case either do not specify a B<preeditStyle> or specify more than
552 one pre-edit style, such as B<OverTheSpot,Root,None>.
554 =head2 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
556 Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
557 international keyboards) or simply use ISO 14755 support to your
558 advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
559 codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
562 =head2 How can I keep rxvt-unicode from using reverse video so much?
564 First of all, make sure you are running with the right terminal settings
565 (C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
566 make sure you have specified colours for italic and bold, as otherwise
567 rxvt-unicode might use reverse video to simulate the effect:
572 =head2 Some programs assume totally weird colours (red instead of blue), how can I fix that?
574 For some unexplainable reason, some rare programs assume a very weird
575 colour palette when confronted with a terminal with more than the standard
576 8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
577 these programs not to assume non-ISO colours without very good reasons.
579 In the meantime, you can either edit your C<rxvt-unicode> terminfo
580 definition to only claim 8 colour support or use C<TERM=rxvt>, which will
581 fix colours but keep you from using other rxvt-unicode features.
583 =head2 I am on FreeBSD and rxvt-unicode does not seem to work at all.
585 Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
586 in your compile environment, or an implementation that implements it,
587 wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
588 B<wchar_t> is represented as unicode.
590 As you might have guessed, FreeBSD does neither define this symobl nor
591 does it support it. Instead, it uses it's own internal representation of
592 B<wchar_t>. This is, of course, completely fine with respect to standards.
594 However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
595 C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
597 C<__STDC_ISO_10646__> is the only sane way to support multi-language
598 apps in an OS, as using a locale-dependent (and non-standardized)
599 representation of B<wchar_t> makes it impossible to convert between
600 B<wchar_t> (as used by X11 and your applications) and any other encoding
601 without implementing OS-specific-wrappers for each and every locale. There
602 simply are no APIs to convert B<wchar_t> into anything except the current
605 Some applications (such as the formidable B<mlterm>) work around this
606 by carrying their own replacement functions for character set handling
607 with them, and either implementing OS-dependent hacks or doing multiple
608 conversions (which is slow and unreliable in case the OS implements
609 encodings slightly different than the terminal emulator).
611 The rxvt-unicode author insists that the right way to fix this is in the
612 system libraries once and for all, instead of forcing every app to carry
613 complete replacements for them :)
615 =head2 I use Solaris 9 and it doesn't compile/work/etc.
617 Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
618 problems with C<wcwidth> and a compile problem.
620 =head2 How can I use rxvt-unicode under cygwin?
622 rxvt-unicode should compile and run out of the box on cygwin, using
623 the X11 libraries that come with cygwin. libW11 emulation is no
624 longer supported (and makes no sense, either, as it only supported a
625 single font). I recommend starting the X-server in C<-multiwindow> or
626 C<-rootless> mode instead, which will result in similar look&feel as the
627 old libW11 emulation.
629 At the time of this writing, cygwin didn't seem to support any multi-byte
630 encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
633 =head2 How does rxvt-unicode determine the encoding to use?
637 =head2 Is there an option to switch encodings?
639 Unlike some other terminals, rxvt-unicode has no encoding switch, and no
640 specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
641 UTF-8 or any other encodings with respect to terminal I/O.
643 The reasons is that there exists a perfectly fine mechanism for selecting
644 the encoding, doing I/O and (most important) communicating this to all
645 applications so everybody agrees on character properties such as width
646 and code number. This mechanism is the I<locale>. Applications not using
647 that info will have problems (for example, C<xterm> gets the width of
648 characters wrong as it uses it's own, locale-independent table under all
651 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
652 programs doing the same (that is, most) will automatically agree in the
653 interpretation of characters.
655 Unfortunately, there is no system-independent way to select locales, nor
656 is there a standard on how locale specifiers will look like.
658 On most systems, the content of the C<LC_CTYPE> environment variable
659 contains an arbitrary string which corresponds to an already-installed
660 locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
661 C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
662 (i.e. C<de> or C<german>) are also common.
664 Rxvt-unicode ignores all other locale categories, and except for
665 the encoding, ignores country or language-specific settings,
666 i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
669 If you want to use a specific encoding you have to make sure you start
670 rxvt-unicode with the correct C<LC_CTYPE> category.
672 =head2 Can I switch locales at runtime?
674 Yes, using an escape sequence. Try something like this, which sets
675 rxvt-unicode's idea of C<LC_CTYPE>.
677 printf '\e]701;%s\007' ja_JP.SJIS
679 See also the previous answer.
681 Sometimes this capability is rather handy when you want to work in
682 one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
683 (e.g. UTF-8). For example, I use this script to start C<xjdic>, which
684 first switches to a locale supported by xjdic and back later:
686 printf '\e]701;%s\007' ja_JP.SJIS
688 printf '\e]701;%s\007' de_DE.UTF-8
690 You can also use xterm's C<luit> program, which usually works fine, except
691 for some locales where character width differs between program- and
692 rxvt-unicode-locales.
694 =head2 Can I switch the fonts at runtime?
696 Yes, using an escape sequence. Try something like this, which has the same
697 effect as using the C<-fn> switch, and takes effect immediately:
699 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
701 This is useful if you e.g. work primarily with japanese (and prefer a
702 japanese font), but you have to switch to chinese temporarily, where
703 japanese fonts would only be in your way.
705 You can think of this as a kind of manual ISO-2022 switching.
707 =head2 Why do italic characters look as if clipped?
709 Many fonts have difficulties with italic characters and hinting. For
710 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
711 Mono> completely fails in it's italic face. A workaround might be to
712 enable freetype autohinting, i.e. like this:
714 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
715 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
717 =head2 My input method wants <some encoding> but I want UTF-8, what can I do?
719 You can specify separate locales for the input method and the rest of the
720 terminal, using the resource C<imlocale>:
722 URxvt.imlocale: ja_JP.EUC-JP
724 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
725 use your input method. Please note, however, that you will not be able to
726 input characters outside C<EUC-JP> in a normal way then, as your input
729 =head2 Rxvt-unicode crashes when the X Input Method changes or exits.
731 Unfortunately, this is unavoidable, as the XIM protocol is racy by
732 design. Applications can avoid some crashes at the expense of memory
733 leaks, and Input Methods can avoid some crashes by careful ordering at
734 exit time. B<kinput2> (and derived input methods) generally succeeds,
735 while B<SCIM> (or similar input methods) fails. In the end, however,
736 crashes cannot be completely avoided even if both sides cooperate.
738 So the only workaround is not to kill your Input Method Servers.
740 =head2 Rxvt-unicode uses gobs of memory, how can I reduce that?
742 Rxvt-unicode tries to obey the rule of not charging you for something you
743 don't use. One thing you should try is to configure out all settings that
744 you don't need, for example, Xft support is a resource hog by design,
745 when used. Compiling it out ensures that no Xft font will be loaded
746 accidentally when rxvt-unicode tries to find a font for your characters.
748 Also, many people (me included) like large windows and even larger
749 scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
750 6 bytes per screen cell. For a 160x?? window this amounts to almost a
751 kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
752 use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
753 rxvt-unicode then uses 8 bytes per screen cell.
755 =head2 Can I speed up Xft rendering somehow?
757 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
758 it is simply slow. If you still want Xft fonts you might try to disable
759 antialiasing (by appending C<:antialias=false>), which saves lots of
760 memory and also speeds up rendering considerably.
762 =head2 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
764 Rxvt-unicode will use whatever you specify as a font. If it needs to
765 fall back to it's default font search list it will prefer X11 core
766 fonts, because they are small and fast, and then use Xft fonts. It has
767 antialiasing disabled for most of them, because the author thinks they
770 If you want antialiasing, you have to specify the fonts manually.
772 =head2 Mouse cut/paste suddenly no longer works.
774 Make sure that mouse reporting is actually turned off since killing
775 some editors prematurely may leave the mouse in mouse report mode. I've
776 heard that tcsh may use mouse reporting unless it otherwise specified. A
777 quick check is to see if cut/paste works when the Alt or Shift keys are
780 =head2 What's with this bold/blink stuff?
782 If no bold colour is set via C<colorBD:>, bold will invert text using the
783 standard foreground colour.
785 For the standard background colour, blinking will actually make the
786 text blink when compiled with C<--enable-blinking>. with standard
787 colours. Without C<--enable-blinking>, the blink attribute will be
790 On ANSI colours, bold/blink attributes are used to set high-intensity
791 foreground/background colors.
793 color0-7 are the low-intensity colors.
795 color8-15 are the corresponding high-intensity colors.
797 =head2 I don't like the screen colors. How do I change them?
799 You can change the screen colors at run-time using F<~/.Xdefaults>
800 resources (or as long-options).
802 Here are values that are supposed to resemble a VGA screen,
803 including the murky brown that passes for low-intensity yellow:
805 URxvt.color0: #000000
806 URxvt.color1: #A80000
807 URxvt.color2: #00A800
808 URxvt.color3: #A8A800
809 URxvt.color4: #0000A8
810 URxvt.color5: #A800A8
811 URxvt.color6: #00A8A8
812 URxvt.color7: #A8A8A8
814 URxvt.color8: #000054
815 URxvt.color9: #FF0054
816 URxvt.color10: #00FF54
817 URxvt.color11: #FFFF54
818 URxvt.color12: #0000FF
819 URxvt.color13: #FF00FF
820 URxvt.color14: #00FFFF
821 URxvt.color15: #FFFFFF
823 And here is a more complete set of non-standard colors described (not by
824 me) as "pretty girly".
826 URxvt.cursorColor: #dc74d1
827 URxvt.pointerColor: #dc74d1
828 URxvt.background: #0e0e0e
829 URxvt.foreground: #4ad5e1
830 URxvt.color0: #000000
831 URxvt.color8: #8b8f93
832 URxvt.color1: #dc74d1
833 URxvt.color9: #dc74d1
834 URxvt.color2: #0eb8c7
835 URxvt.color10: #0eb8c7
836 URxvt.color3: #dfe37e
837 URxvt.color11: #dfe37e
838 URxvt.color5: #9e88f0
839 URxvt.color13: #9e88f0
840 URxvt.color6: #73f7ff
841 URxvt.color14: #73f7ff
842 URxvt.color7: #e1dddd
843 URxvt.color15: #e1dddd
845 =head2 How can I start @@RXVT_NAME@@d in a race-free way?
847 Try C<@@RXVT_NAME@@d -f -o>, which tells @@RXVT_NAME@@d to open the
848 display, create the listening socket and then fork.
850 =head2 What's with the strange Backspace/Delete key behaviour?
852 Assuming that the physical Backspace key corresponds to the
853 BackSpace keysym (not likely for Linux ... see the following
854 question) there are two standard values that can be used for
855 Backspace: C<^H> and C<^?>.
857 Historically, either value is correct, but rxvt-unicode adopts the debian
858 policy of using C<^?> when unsure, because it's the one only only correct
861 Rxvt-unicode tries to inherit the current stty settings and uses the value
862 of `erase' to guess the value for backspace. If rxvt-unicode wasn't
863 started from a terminal (say, from a menu or by remote shell), then the
864 system value of `erase', which corresponds to CERASE in <termios.h>, will
865 be used (which may not be the same as your stty setting).
867 For starting a new rxvt-unicode:
877 Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
879 For an existing rxvt-unicode:
889 This helps satisfy some of the Backspace discrepancies that occur, but
890 if you use Backspace = C<^H>, make sure that the termcap/terminfo value
891 properly reflects that.
893 The Delete key is a another casualty of the ill-defined Backspace problem.
894 To avoid confusion between the Backspace and Delete keys, the Delete
895 key has been assigned an escape sequence to match the vt100 for Execute
896 (C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
898 Some other Backspace problems:
900 some editors use termcap/terminfo,
901 some editors (vim I'm told) expect Backspace = ^H,
902 GNU Emacs (and Emacs-like editors) use ^H for help.
904 Perhaps someday this will all be resolved in a consistent manner.
906 =head2 I don't like the key-bindings. How do I change them?
908 There are some compile-time selections available via configure. Unless
909 you have run "configure" with the C<--disable-resources> option you can
910 use the `keysym' resource to alter the keystrings associated with keysyms.
912 Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
914 URxvt.keysym.Home: \033[1~
915 URxvt.keysym.End: \033[4~

933 URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
935 See some more examples in the documentation for the B<keysym> resource.
937 =head2 I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
938 How do I make use of them? For example, the Sun Keyboard type 4
939 has the following mappings that rxvt-unicode doesn't recognize.
948 Rather than have rxvt-unicode try to accommodate all the various possible
949 keyboard mappings, it is better to use `xmodmap' to remap the keys as
950 required for your particular machine.
952 =head2 How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
953 I need this to decide about setting colors etc.
955 rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
956 check and see if that is set. Note that several programs, JED, slrn,
957 Midnight Commander automatically check this variable to decide whether or
960 =head2 How do I set the correct, full IP address for the DISPLAY variable?
962 If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
963 insecure mode then it is possible to use the following shell script
964 snippets to correctly set the display. If your version of rxvt-unicode
965 wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
966 the COLORTERM variable can be used to distinguish rxvt-unicode from a

985 =head2 How do I compile the manual pages for myself?
987 You need to have a recent version of perl installed as F</usr/bin/perl>,
988 one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
989 the doc subdirectory and enter C<make alldoc>.
991 =head2 My question isn't answered here, can I ask a human?
993 Before sending me mail, you could go to IRC: C<irc.freenode.net>,
994 channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
995 interested in learning about new and exciting problems (but not FAQs :).

1989 =head1 CONFIGURE OPTIONS
1991 General hint: if you get compile errors, then likely your configuration
1992 hasn't been tested well. Either try with C<--enable-everything> or use
1993 the F<./reconf> script as a base for experiments. F<./reconf> is used by
1994 myself, so it should generally be a working config. Of course, you should
1995 always report when a combination doesn't work, so it can be fixed. Marc
1996 Lehmann <rxvt@schmorp.de>.
2002 =item --enable-everything
2004 Add (or remove) support for all non-multichoice options listed in "./configure
2007 You can specify this and then disable options you do not like by
2008 I<following> this with the appropriate C<--disable-...> arguments,
2009 or you can start with a minimal configuration by specifying
2010 C<--disable-everything> and than adding just the C<--enable-...> arguments
2013 =item --enable-xft (default: enabled)
2015 Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
2016 slower and require lots of memory, but as long as you don't use them, you
2019 =item --enable-font-styles (default: on)
2021 Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
2022 styles. The fonts can be set manually or automatically.
2024 =item --with-codesets=NAME,... (default: all)
2026 Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
2027 are always compiled in, which includes most 8-bit character sets). These
2028 codeset tables are used for driving X11 core fonts, they are not required
2029 for Xft fonts, although having them compiled in lets rxvt-unicode choose
2030 replacement fonts more intelligently. Compiling them in will make your
2031 binary bigger (all of together cost about 700kB), but it doesn't increase
2032 memory usage unless you use a font requiring one of these encodings.
2036 all all available codeset groups
2037 zh common chinese encodings
2038 zh_ext rarely used but very big chinese encodigs
2039 jp common japanese encodings
2040 jp_ext rarely used but big japanese encodings
2045 =item --enable-xim (default: on)
2047 Add support for XIM (X Input Method) protocol. This allows using
2048 alternative input methods (e.g. kinput2) and will also correctly
2049 set up the input for people using dead keys or compose keys.
2051 =item --enable-unicode3 (default: off)
2053 Recommended to stay off unless you really need non-BMP characters.
2055 Enable direct support for displaying unicode codepoints above
2056 65535 (the basic multilingual page). This increases storage
2057 requirements per character from 2 to 4 bytes. X11 fonts do not yet
2058 support these extra characters, but Xft does.
2060 Please note that rxvt-unicode can store unicode code points >65535
2061 even without this flag, but the number of such characters is
2062 limited to a view thousand (shared with combining characters,
2063 see next switch), and right now rxvt-unicode cannot display them
2064 (input/output and cut&paste still work, though).
2066 =item --enable-combining (default: on)
2068 Enable automatic composition of combining characters into
2069 composite characters. This is required for proper viewing of text
2070 where accents are encoded as seperate unicode characters. This is
2071 done by using precomposited characters when available or creating
2072 new pseudo-characters when no precomposed form exists.
2074 Without --enable-unicode3, the number of additional precomposed
2075 characters is somewhat limited (the 6400 private use characters will be
2076 (ab-)used). With --enable-unicode3, no practical limit exists.
2078 This option will also enable storage (but not display) of characters
2079 beyond plane 0 (>65535) when --enable-unicode3 was not specified.
2081 The combining table also contains entries for arabic presentation forms,
2082 but these are not currently used. Bug me if you want these to be used (and
2083 tell me how these are to be used...).
2085 =item --enable-fallback(=CLASS) (default: Rxvt)
2087 When reading resource settings, also read settings for class CLASS. To
2088 disable resource fallback use --disable-fallback.
2090 =item --with-res-name=NAME (default: urxvt)
2092 Use the given name as default application name when
2093 reading resources. Specify --with-res-name=rxvt to replace rxvt.
2095 =item --with-res-class=CLASS /default: URxvt)
2097 Use the given class as default application class
2098 when reading resources. Specify --with-res-class=Rxvt to replace
2101 =item --enable-utmp (default: on)
2103 Write user and tty to utmp file (used by programs like F<w>) at
2104 start of rxvt execution and delete information when rxvt exits.
2106 =item --enable-wtmp (default: on)
2108 Write user and tty to wtmp file (used by programs like F<last>) at
2109 start of rxvt execution and write logout when rxvt exits. This
2110 option requires --enable-utmp to also be specified.
2112 =item --enable-lastlog (default: on)
2114 Write user and tty to lastlog file (used by programs like
2115 F<lastlogin>) at start of rxvt execution. This option requires
2116 --enable-utmp to also be specified.
2118 =item --enable-xpm-background (default: on)
2120 Add support for XPM background pixmaps.
2122 =item --enable-transparency (default: on)
2124 Add support for inheriting parent backgrounds thus giving a fake
2125 transparency to the term.
2127 =item --enable-fading (default: on)
2129 Add support for fading the text when focus is lost (requires C<--enable-transparency>).
2131 =item --enable-tinting (default: on)
2133 Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
2135 =item --enable-rxvt-scroll (default: on)
2137 Add support for the original rxvt scrollbar.
2139 =item --enable-next-scroll (default: on)
2141 Add support for a NeXT-like scrollbar.
2143 =item --enable-xterm-scroll (default: on)
2145 Add support for an Xterm-like scrollbar.
2147 =item --enable-plain-scroll (default: on)
2149 Add support for a very unobtrusive, plain-looking scrollbar that
2150 is the favourite of the rxvt-unicode author, having used it for
2153 =item --enable-ttygid (default: off)
2155 Change tty device setting to group "tty" - only use this if
2156 your system uses this type of security.
2158 =item --disable-backspace-key
2160 Removes any handling of the backspace key by us - let the X server do it.
2162 =item --disable-delete-key
2164 Removes any handling of the delete key by us - let the X server
2167 =item --disable-resources
2169 Removes any support for resource checking.
2171 =item --disable-swapscreen
2173 Remove support for secondary/swap screen.
2175 =item --enable-frills (default: on)
2177 Add support for many small features that are not essential but nice to
2178 have. Normally you want this, but for very small binaries you may want to
2181 A non-exhaustive list of features enabled by C<--enable-frills> (possibly
2182 in combination with other switches) is:
2185 EWMH-hints (pid, utf8 names) and protocols (ping)
2186 seperate underline colour (-underlineColor)
2187 settable border widths and borderless switch (-w, -b, -bl)
2188 visual depth selection (-depth)
2189 settable extra linespacing /-lsp)
2190 iso-14755-2 and -3, and visual feedback
2191 tripleclickwords (-tcw)
2192 settable insecure mode (-insecure)
2193 keysym remapping support
2194 cursor blinking and underline cursor (-cb, -uc)
2195 XEmbed support (-embed)
2197 hold on exit (-hold)
2198 skip builtin block graphics (-sbg)
2200 It also enabled some non-essential features otherwise disabled, such as:
2202 some round-trip time optimisations
2203 nearest color allocation on pseudocolor screens
2204 UTF8_STRING supporr for selection
2205 sgr modes 90..97 and 100..107
2206 backindex and forwardindex escape sequences
2207 view change/zero scorllback esacpe sequences
2208 locale switching escape sequence
2209 window op and some xterm/OSC escape sequences
2210 rectangular selections
2211 trailing space removal for selections
2212 verbose X error handling
2214 =item --enable-iso14755 (default: on)
2216 Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
2217 F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
2218 C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
2221 =item --enable-keepscrolling (default: on)
2223 Add support for continual scrolling of the display when you hold
2224 the mouse button down on a scrollbar arrow.
2226 =item --enable-mousewheel (default: on)
2228 Add support for scrolling via mouse wheel or buttons 4 & 5.
2230 =item --enable-slipwheeling (default: on)
2232 Add support for continual scrolling (using the mouse wheel as an
2233 accelerator) while the control key is held down. This option
2234 requires --enable-mousewheel to also be specified.
2236 =item --disable-new-selection
2238 Remove support for mouse selection style like that of xterm.
2240 =item --enable-dmalloc (default: off)
2242 Use Gray Watson's malloc - which is good for debugging See
2243 http://www.letters.com/dmalloc/ for details If you use either this or the
2244 next option, you may need to edit src/Makefile after compiling to point
2245 DINCLUDE and DLIB to the right places.
2247 You can only use either this option and the following (should
2250 =item --enable-dlmalloc (default: off)
2252 Use Doug Lea's malloc - which is good for a production version
2253 See L<http://g.oswego.edu/dl/html/malloc.html> for details.
2255 =item --enable-smart-resize (default: on)
2257 Add smart growth/shrink behaviour when changing font size via hot
2258 keys. This should keep the window corner which is closest to a corner of
2259 the screen in a fixed position.
2261 =item --enable-pointer-blank (default: on)
2263 Add support to have the pointer disappear when typing or inactive.
2265 =item --enable-perl (default: on)
2267 Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
2268 manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the files
2269 in F<src/perl-ext/> for the extensions that are installed by default. The
2270 perl interpreter that is used can be specified via the C<PERL> environment
2271 variable when running configure.
2273 =item --with-name=NAME (default: urxvt)
2275 Set the basename for the installed binaries, resulting
2276 in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
2279 =item --with-term=NAME (default: rxvt-unicode)
2281 Change the environmental variable for the terminal to NAME.
2283 =item --with-terminfo=PATH
2285 Change the environmental variable for the path to the terminfo tree to
2290 Use the X Window System (pretty much default, eh?).
2292 =item --with-xpm-includes=DIR
2294 Look for the XPM includes in DIR.
2296 =item --with-xpm-library=DIR
2298 Look for the XPM library in DIR.
2302 Not needed - define via --enable-xpm-background.
