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. Before
165 reporting a bug to the original rxvt-unicode author please download and
166 install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
167 and try to reproduce the problem. If you cannot, chances are that the
168 problems are specific to Debian GNU/Linux, in which case it should be
169 reported via the Debian Bug Tracking System (use C<reportbug> to report
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 recommendation?
179 You should build one binary with the default options. F<configure>
180 now enables most useful options, and the trend goes to making them
181 runtime-switchable, too, so there is usually no drawback to enbaling them,
182 except higher disk and possibly memory usage. The perl interpreter should
183 be enabled, as important functionality (menus, selection, likely more in
184 the future) depends on it.
186 You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
187 system-wide (except maybe with C<defaults>). This will result in useful
188 behaviour. If your distribution aims at low memory, add an empty
189 C<perl-ext-common> resource to the app-defaults file. This will keep the
190 perl interpreter disabled until the user enables it.
192 If you can/want build more binaries, I recommend building a minimal
193 one with C<--disable-everything> (very useful) and a maximal one with
194 C<--enable-everything> (less useful, it will be very big due to a lot of
195 encodings built-in that increase download times and are rarely used).
197 =item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
199 Likely not. While I honestly try to make it secure, and am probably not
200 bad at it, I think it is simply unreasonable to expect all of freetype
201 + fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202 secure. Also, rxvt-unicode disables some options when it detects that it
203 runs setuid or setgid, which is not nice. Besides, with the embedded perl
204 interpreter the possibility for security problems easily multiplies.
206 Elevated privileges are only required for utmp and pty operations on some
207 systems (for example, GNU/Linux doesn't need any extra privileges for
208 ptys, but some need it for utmp support). It is planned to mvoe this into
209 a forked handler process, but this is not yet done.
211 So, while setuid/setgid operation is supported and not a problem on your
212 typical single-user-no-other-logins unix desktop, always remember that
213 its an awful lot of code, most of which isn't checked for security issues
216 =item When I log-in to another system it tells me about missing terminfo data?
218 The terminal description used by rxvt-unicode is not as widely available
219 as that for xterm, or even rxvt (for which the same problem often arises).
221 The correct solution for this problem is to install the terminfo, this can
222 be done like this (with ncurses' infocmp):
224 REMOTE=remotesystem.domain
225 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
227 ... or by installing rxvt-unicode normally on the remote system,
229 If you cannot or do not want to do this, then you can simply set
230 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
231 problems arising, which includes wrong keymapping, less and different
232 colours and some refresh errors in fullscreen applications. It's a nice
233 quick-and-dirty workaround for rare cases, though.
235 If you always want to do this (and are fine with the consequences) you
236 can either recompile rxvt-unicode with the desired TERM value or use a
241 If you don't plan to use B<rxvt> (quite common...) you could also replace
242 the rxvt terminfo file with the rxvt-unicode one.
244 =item C<tic> outputs some error when compiling the terminfo entry.
246 Most likely it's the empty definition for C<enacs=>. Just replace it by
247 C<enacs=\E[0@> and try again.
249 =item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
251 =item I need a termcap file entry.
253 One reason you might want this is that some distributions or operating
254 systems still compile some programs using the long-obsoleted termcap
255 library (Fedora Core's bash is one example) and rely on a termcap entry
258 You could use rxvt's termcap entry with resonable results in many cases.
259 You can also create a termcap entry by using terminfo's infocmp program
262 infocmp -C rxvt-unicode
264 Or you could use this termcap entry, generated by the command above:

287 =item Why does C<ls> no longer have coloured output?
289 The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
290 decide wether a terminal has colour, but uses it's own configuration
291 file. Needless to say, C<rxvt-unicode> is not in it's default file (among
292 with most other terminals supporting colour). Either add:
296 to C</etc/DIR_COLORS> or simply add:
298 alias ls='ls --color=auto'
300 to your C<.profile> or C<.bashrc>.
302 =item Why doesn't vim/emacs etc. use the 88 colour mode?
304 =item Why doesn't vim/emacs etc. make use of italic?
306 =item Why are the secondary screen-related options not working properly?
308 Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
309 distributions (most notably Debian GNU/Linux) break rxvt-unicode
310 by setting C<TERM> to C<rxvt>, which doesn't have these extra
311 features. Unfortunately, some of these (most notably, again, Debian
312 GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
313 file, so you will need to install it on your own (See the question B<When
314 I log-in to another system it tells me about missing terminfo data?> on
317 =item My numerical keypad acts weird and generates differing output?
319 Some Debian GNUL/Linux users seem to have this problem, although no
320 specific details were reported so far. It is possible that this is caused
321 by the wrong C<TERM> setting, although the details of wether and how
322 this can happen are unknown, as C<TERM=rxvt> should offer a compatible
323 keymap. See the answer to the previous question, and please report if that
326 =item Rxvt-unicode does not seem to understand the selected encoding?
328 =item Unicode does not seem to work?
330 If you encounter strange problems like typing an accented character but
331 getting two unrelated other characters or similar, or if program output is
332 subtly garbled, then you should check your locale settings.
334 Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
335 programs. Often rxvt-unicode is started in the C<C> locale, while the
336 login script running within the rxvt-unicode window changes the locale to
337 something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
339 The best thing is to fix your startup environment, as you will likely run
340 into other problems. If nothing works you can try this in your .profile.
342 printf '\e]701;%s\007' "$LC_CTYPE"
344 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
345 supported on your systems. Some systems have a C<locale> command which
346 displays this (also, C<perl -e0> can be used to check locale settings, as
347 it will complain loudly if it cannot set the locale). If it displays something
350 locale: Cannot set LC_CTYPE to default locale: ...
352 Then the locale you specified is not supported on your system.
354 If nothing works and you are sure that everything is set correctly then
355 you will need to remember a little known fact: Some programs just don't
358 =item Why do some characters look so much different than others?
360 =item How does rxvt-unicode choose fonts?
362 Most fonts do not contain the full range of Unicode, which is
363 fine. Chances are that the font you (or the admin/package maintainer of
364 your system/os) have specified does not cover all the characters you want
367 B<rxvt-unicode> makes a best-effort try at finding a replacement
368 font. Often the result is fine, but sometimes the chosen font looks
369 bad/ugly/wrong. Some fonts have totally strange characters that don't
370 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
371 intelligence to detect that a specific glyph is wrong: it has to believe
372 the font that the characters it claims to contain indeed look correct.
374 In that case, select a font of your taste and add it to the font list,
377 @@RXVT_NAME@@ -fn basefont,font2,font3...
379 When rxvt-unicode sees a character, it will first look at the base
380 font. If the base font does not contain the character, it will go to the
381 next font, and so on. Specifying your own fonts will also speed up this
382 search and use less resources within rxvt-unicode and the X-server.
384 The only limitation is that none of the fonts may be larger than the base
385 font, as the base font defines the terminal character cell size, which
386 must be the same due to the way terminals work.
388 =item Why do some chinese characters look so different than others?
390 This is because there is a difference between script and language --
391 rxvt-unicode does not know which language the text that is output is,
392 as it only knows the unicode character codes. If rxvt-unicode first
393 sees a japanese/chinese character, it might choose a japanese font for
394 display. Subsequent japanese characters will use that font. Now, many
395 chinese characters aren't represented in japanese fonts, so when the first
396 non-japanese character comes up, rxvt-unicode will look for a chinese font
397 -- unfortunately at this point, it will still use the japanese font for
398 chinese characters that are also in the japanese font.
400 The workaround is easy: just tag a chinese font at the end of your font
401 list (see the previous question). The key is to view the font list as
402 a preference list: If you expect more japanese, list a japanese font
403 first. If you expect more chinese, put a chinese font first.
405 In the future it might be possible to switch language preferences at
406 runtime (the internal data structure has no problem with using different
407 fonts for the same character at the same time, but no interface for this
408 has been designed yet).
410 Until then, you might get away with switching fonts at runtime (see L<Can
411 I switch the fonts at runtime?> later in this document).
413 =item Why does rxvt-unicode sometimes leave pixel droppings?
415 Most fonts were not designed for terminal use, which means that character
416 size varies a lot. A font that is otherwise fine for terminal use might
417 contain some characters that are simply too wide. Rxvt-unicode will avoid
418 these characters. For characters that are just "a bit" too wide a special
419 "careful" rendering mode is used that redraws adjacent characters.
421 All of this requires that fonts do not lie about character sizes,
422 however: Xft fonts often draw glyphs larger than their acclaimed bounding
423 box, and rxvt-unicode has no way of detecting this (the correct way is to
424 ask for the character bounding box, which unfortunately is wrong in these
427 It's not clear (to me at least), wether this is a bug in Xft, freetype,
428 or the respective font. If you encounter this problem you might try using
429 the C<-lsp> option to give the font more height. If that doesn't work, you
430 might be forced to use a different font.
432 All of this is not a problem when using X11 core fonts, as their bounding
435 =item On Solaris 9, many line-drawing characters are too wide.
437 Seems to be a known bug, read
438 L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
439 following ugly workaround to get non-double-wide-characters working:
441 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
443 =item My Compose (Multi_key) key is no longer working.
445 The most common causes for this are that either your locale is not set
446 correctly, or you specified a B<preeditStyle> that is not supported by
447 your input method. For example, if you specified B<OverTheSpot> and
448 your input method (e.g. the default input method handling Compose keys)
449 does not support this (for instance because it is not visual), then
450 rxvt-unicode will continue without an input method.
452 In this case either do not specify a B<preeditStyle> or specify more than
453 one pre-edit style, such as B<OverTheSpot,Root,None>.
455 =item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
457 Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
458 international keyboards) or simply use ISO 14755 support to your
459 advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
460 codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
463 =item How can I keep rxvt-unicode from using reverse video so much?
465 First of all, make sure you are running with the right terminal settings
466 (C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
467 make sure you have specified colours for italic and bold, as otherwise
468 rxvt-unicode might use reverse video to simulate the effect:
473 =item Some programs assume totally weird colours (red instead of blue), how can I fix that?
475 For some unexplainable reason, some rare programs assume a very weird
476 colour palette when confronted with a terminal with more than the standard
477 8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
478 these programs not to assume non-ISO colours without very good reasons.
480 In the meantime, you can either edit your C<rxvt-unicode> terminfo
481 definition to only claim 8 colour support or use C<TERM=rxvt>, which will
482 fix colours but keep you from using other rxvt-unicode features.
484 =item I am on FreeBSD and rxvt-unicode does not seem to work at all.
486 Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
487 in your compile environment, or an implementation that implements it,
488 wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
489 B<wchar_t> is represented as unicode.
491 As you might have guessed, FreeBSD does neither define this symobl nor
492 does it support it. Instead, it uses it's own internal representation of
493 B<wchar_t>. This is, of course, completely fine with respect to standards.
495 However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
496 C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
498 C<__STDC_ISO_10646__> is the only sane way to support multi-language
499 apps in an OS, as using a locale-dependent (and non-standardized)
500 representation of B<wchar_t> makes it impossible to convert between
501 B<wchar_t> (as used by X11 and your applications) and any other encoding
502 without implementing OS-specific-wrappers for each and every locale. There
503 simply are no APIs to convert B<wchar_t> into anything except the current
506 Some applications (such as the formidable B<mlterm>) work around this
507 by carrying their own replacement functions for character set handling
508 with them, and either implementing OS-dependent hacks or doing multiple
509 conversions (which is slow and unreliable in case the OS implements
510 encodings slightly different than the terminal emulator).
512 The rxvt-unicode author insists that the right way to fix this is in the
513 system libraries once and for all, instead of forcing every app to carry
514 complete replacements for them :)
516 =item I use Solaris 9 and it doesn't compile/work/etc.

519 problems with C<wcwidth> and a compile problem.
521 =item How can I use rxvt-unicode under cygwin?
523 rxvt-unicode should compile and run out of the box on cygwin, using
524 the X11 libraries that come with cygwin. libW11 emulation is no
525 longer supported (and makes no sense, either, as it only supported a
526 single font). I recommend starting the X-server in C<-multiwindow> or
527 C<-rootless> mode instead, which will result in similar look&feel as the
528 old libW11 emulation.
530 At the time of this writing, cygwin didn't seem to support any multi-byte
531 encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
534 =item How does rxvt-unicode determine the encoding to use?
536 =item Is there an option to switch encodings?
538 Unlike some other terminals, rxvt-unicode has no encoding switch, and no
539 specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
540 UTF-8 or any other encodings with respect to terminal I/O.
542 The reasons is that there exists a perfectly fine mechanism for selecting
543 the encoding, doing I/O and (most important) communicating this to all
544 applications so everybody agrees on character properties such as width
545 and code number. This mechanism is the I<locale>. Applications not using
546 that info will have problems (for example, C<xterm> gets the width of
547 characters wrong as it uses it's own, locale-independent table under all
550 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
551 programs doing the same (that is, most) will automatically agree in the
552 interpretation of characters.
554 Unfortunately, there is no system-independent way to select locales, nor
555 is there a standard on how locale specifiers will look like.
557 On most systems, the content of the C<LC_CTYPE> environment variable
558 contains an arbitrary string which corresponds to an already-installed
559 locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
560 C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
561 (i.e. C<de> or C<german>) are also common.
563 Rxvt-unicode ignores all other locale categories, and except for
564 the encoding, ignores country or language-specific settings,
565 i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
568 If you want to use a specific encoding you have to make sure you start
569 rxvt-unicode with the correct C<LC_CTYPE> category.
571 =item Can I switch locales at runtime?
573 Yes, using an escape sequence. Try something like this, which sets
574 rxvt-unicode's idea of C<LC_CTYPE>.
576 printf '\e]701;%s\007' ja_JP.SJIS
578 See also the previous answer.
580 Sometimes this capability is rather handy when you want to work in
581 one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
582 (e.g. UTF-8). For example, I use this script to start C<xjdic>, which
583 first switches to a locale supported by xjdic and back later:
585 printf '\e]701;%s\007' ja_JP.SJIS
587 printf '\e]701;%s\007' de_DE.UTF-8
589 You can also use xterm's C<luit> program, which usually works fine, except
590 for some locales where character width differs between program- and
591 rxvt-unicode-locales.
593 =item Can I switch the fonts at runtime?
595 Yes, using an escape sequence. Try something like this, which has the same
596 effect as using the C<-fn> switch, and takes effect immediately:
598 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
600 This is useful if you e.g. work primarily with japanese (and prefer a
601 japanese font), but you have to switch to chinese temporarily, where
602 japanese fonts would only be in your way.
604 You can think of this as a kind of manual ISO-2022 switching.
606 =item Why do italic characters look as if clipped?
608 Many fonts have difficulties with italic characters and hinting. For
609 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
610 Mono> completely fails in it's italic face. A workaround might be to
611 enable freetype autohinting, i.e. like this:
613 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
614 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
616 =item My input method wants <some encoding> but I want UTF-8, what can I do?
618 You can specify separate locales for the input method and the rest of the
619 terminal, using the resource C<imlocale>:
621 URxvt.imlocale: ja_JP.EUC-JP
623 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
624 use your input method. Please note, however, that you will not be able to
625 input characters outside C<EUC-JP> in a normal way then, as your input
628 =item Rxvt-unicode crashes when the X Input Method changes or exits.
630 Unfortunately, this is unavoidable, as the XIM protocol is racy by
631 design. Applications can avoid some crashes at the expense of memory
632 leaks, and Input Methods can avoid some crashes by careful ordering at
633 exit time. B<kinput2> (and derived input methods) generally succeeds,
634 while B<SCIM> (or similar input methods) fails. In the end, however,
635 crashes cannot be completely avoided even if both sides cooperate.
637 So the only workaround is not to kill your Input Method Servers.
639 =item Rxvt-unicode uses gobs of memory, how can I reduce that?
641 Rxvt-unicode tries to obey the rule of not charging you for something you
642 don't use. One thing you should try is to configure out all settings that
643 you don't need, for example, Xft support is a resource hog by design,
644 when used. Compiling it out ensures that no Xft font will be loaded
645 accidentally when rxvt-unicode tries to find a font for your characters.
647 Also, many people (me included) like large windows and even larger
648 scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
649 6 bytes per screen cell. For a 160x?? window this amounts to almost a
650 kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
651 use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
652 rxvt-unicode then uses 8 bytes per screen cell.
654 =item Can I speed up Xft rendering somehow?
656 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
657 it is simply slow. If you still want Xft fonts you might try to disable
658 antialiasing (by appending C<:antialias=false>), which saves lots of
659 memory and also speeds up rendering considerably.
661 =item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
663 Rxvt-unicode will use whatever you specify as a font. If it needs to
664 fall back to it's default font search list it will prefer X11 core
665 fonts, because they are small and fast, and then use Xft fonts. It has
666 antialiasing disabled for most of them, because the author thinks they
669 If you want antialiasing, you have to specify the fonts manually.
671 =item Mouse cut/paste suddenly no longer works.
673 Make sure that mouse reporting is actually turned off since killing
674 some editors prematurely may leave the mouse in mouse report mode. I've
675 heard that tcsh may use mouse reporting unless it otherwise specified. A
676 quick check is to see if cut/paste works when the Alt or Shift keys are
679 =item What's with this bold/blink stuff?
681 If no bold colour is set via C<colorBD:>, bold will invert text using the
682 standard foreground colour.
684 For the standard background colour, blinking will actually make the
685 text blink when compiled with C<--enable-blinking>. with standard
686 colours. Without C<--enable-blinking>, the blink attribute will be
689 On ANSI colours, bold/blink attributes are used to set high-intensity
690 foreground/background colors.
692 color0-7 are the low-intensity colors.
694 color8-15 are the corresponding high-intensity colors.
696 =item I don't like the screen colors. How do I change them?
698 You can change the screen colors at run-time using F<~/.Xdefaults>
699 resources (or as long-options).
701 Here are values that are supposed to resemble a VGA screen,
702 including the murky brown that passes for low-intensity yellow:
704 URxvt.color0: #000000
705 URxvt.color1: #A80000
706 URxvt.color2: #00A800
707 URxvt.color3: #A8A800
708 URxvt.color4: #0000A8
709 URxvt.color5: #A800A8
710 URxvt.color6: #00A8A8

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

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

836 =item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
837 How do I make use of them? For example, the Sun Keyboard type 4
838 has the following mappings that rxvt-unicode doesn't recognize.
847 Rather than have rxvt-unicode try to accommodate all the various possible
848 keyboard mappings, it is better to use `xmodmap' to remap the keys as
849 required for your particular machine.
851 =item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
852 I need this to decide about setting colors etc.
854 rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
855 check and see if that is set. Note that several programs, JED, slrn,
856 Midnight Commander automatically check this variable to decide whether or
859 =item How do I set the correct, full IP address for the DISPLAY variable?
861 If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
862 insecure mode then it is possible to use the following shell script
863 snippets to correctly set the display. If your version of rxvt-unicode
864 wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
865 the COLORTERM variable can be used to distinguish rxvt-unicode from a

1889 =head1 CONFIGURE OPTIONS
1891 General hint: if you get compile errors, then likely your configuration
1892 hasn't been tested well. Either try with C<--enable-everything> or use
1893 the F<./reconf> script as a base for experiments. F<./reconf> is used by
1894 myself, so it should generally be a working config. Of course, you should
1895 always report when a combination doesn't work, so it can be fixed. Marc
1896 Lehmann <rxvt@schmorp.de>.
1902 =item --enable-everything
1904 Add (or remove) support for all non-multichoice options listed in "./configure
1907 You can specify this and then disable options you do not like by
1908 I<following> this with the appropriate C<--disable-...> arguments,
1909 or you can start with a minimal configuration by specifying
1910 C<--disable-everything> and than adding just the C<--enable-...> arguments
1913 =item --enable-xft (default: enabled)
1915 Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
1916 slower and require lots of memory, but as long as you don't use them, you
1919 =item --enable-font-styles (default: on)
1921 Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
1922 styles. The fonts can be set manually or automatically.
1924 =item --with-codesets=NAME,... (default: all)
1926 Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
1927 are always compiled in, which includes most 8-bit character sets). These
1928 codeset tables are used for driving X11 core fonts, they are not required
1929 for Xft fonts, although having them compiled in lets rxvt-unicode choose
1930 replacement fonts more intelligently. Compiling them in will make your
1931 binary bigger (all of together cost about 700kB), but it doesn't increase
1932 memory usage unless you use a font requiring one of these encodings.
1936 all all available codeset groups
1937 zh common chinese encodings
1938 zh_ext rarely used but very big chinese encodigs

1947 Add support for XIM (X Input Method) protocol. This allows using
1948 alternative input methods (e.g. kinput2) and will also correctly
1949 set up the input for people using dead keys or compose keys.
1951 =item --enable-unicode3 (default: off)
1953 Enable direct support for displaying unicode codepoints above
1954 65535 (the basic multilingual page). This increases storage
1955 requirements per character from 2 to 4 bytes. X11 fonts do not yet
1956 support these extra characters, but Xft does.
1958 Please note that rxvt-unicode can store unicode code points >65535
1959 even without this flag, but the number of such characters is
1960 limited to a view thousand (shared with combining characters,
1961 see next switch), and right now rxvt-unicode cannot display them
1962 (input/output and cut&paste still work, though).
1964 =item --enable-combining (default: on)
1966 Enable automatic composition of combining characters into
1967 composite characters. This is required for proper viewing of text
1968 where accents are encoded as seperate unicode characters. This is
1969 done by using precomposited characters when available or creating
1970 new pseudo-characters when no precomposed form exists.
1972 Without --enable-unicode3, the number of additional precomposed characters
1973 is rather limited (2048, if this is full, rxvt-unicode will use the
1974 private use area, extending the number of combinations to 8448). With
1975 --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 disable resource fallback use --disable-fallback.
1988 =item --with-res-name=NAME (default: urxvt)
1990 Use the given name as default application name when
1991 reading resources. Specify --with-res-name=rxvt to replace rxvt.
1993 =item --with-res-class=CLASS /default: URxvt)
1995 Use the given class as default application class
1996 when reading resources. Specify --with-res-class=Rxvt to replace
1999 =item --enable-utmp (default: on)
2001 Write user and tty to utmp file (used by programs like F<w>) at
2002 start of rxvt execution and delete information when rxvt exits.
2004 =item --enable-wtmp (default: on)
2006 Write user and tty to wtmp file (used by programs like F<last>) at
2007 start of rxvt execution and write logout when rxvt exits. This
2008 option requires --enable-utmp to also be specified.
2010 =item --enable-lastlog (default: on)
2012 Write user and tty to lastlog file (used by programs like
2013 F<lastlogin>) at start of rxvt execution. This option requires
2014 --enable-utmp to also be specified.
2016 =item --enable-xpm-background (default: on)
2018 Add support for XPM background pixmaps.
2020 =item --enable-transparency (default: on)
2022 Add support for inheriting parent backgrounds thus giving a fake
2023 transparency to the term.
2025 =item --enable-fading (default: on)
2027 Add support for fading the text when focus is lost (requires C<--enable-transparency>).
2029 =item --enable-tinting (default: on)
2031 Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
2033 =item --enable-rxvt-scroll (default: on)
2035 Add support for the original rxvt scrollbar.
2037 =item --enable-next-scroll (default: on)
2039 Add support for a NeXT-like scrollbar.
2041 =item --enable-xterm-scroll (default: on)
2043 Add support for an Xterm-like scrollbar.
2045 =item --enable-plain-scroll (default: on)
2047 Add support for a very unobtrusive, plain-looking scrollbar that
2048 is the favourite of the rxvt-unicode author, having used it for
2051 =item --enable-half-shadow (default: off)
2053 Make shadows on the scrollbar only half the normal width & height.
2054 only applicable to rxvt scrollbars.
2056 =item --enable-ttygid (default: off)
2058 Change tty device setting to group "tty" - only use this if
2059 your system uses this type of security.
2061 =item --disable-backspace-key
2063 Removes any handling of the backspace key by us - let the X server do it.
2065 =item --disable-delete-key
2067 Removes any handling of the delete key by us - let the X server
2070 =item --disable-resources
2072 Removes any support for resource checking.
2074 =item --disable-swapscreen
2076 Remove support for secondary/swap screen.
2078 =item --enable-frills (default: on)
2080 Add support for many small features that are not essential but nice to
2081 have. Normally you want this, but for very small binaries you may want to
2084 A non-exhaustive list of features enabled by C<--enable-frills> (possibly
2085 in combination with other switches) is:
2088 EWMH-hints (pid, utf8 names) and protocols (ping)
2089 seperate underline colour (-underlineColor)

2107 Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
2108 F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
2109 C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
2112 =item --enable-keepscrolling (default: on)
2114 Add support for continual scrolling of the display when you hold
2115 the mouse button down on a scrollbar arrow.

2119 Add support for scrolling via mouse wheel or buttons 4 & 5.
2121 =item --enable-slipwheeling (default: on)
2123 Add support for continual scrolling (using the mouse wheel as an
2124 accelerator) while the control key is held down. This option
2125 requires --enable-mousewheel to also be specified.
2127 =item --disable-new-selection
2129 Remove support for mouse selection style like that of xterm.
2131 =item --enable-dmalloc (default: off)
2133 Use Gray Watson's malloc - which is good for debugging See
2134 http://www.letters.com/dmalloc/ for details If you use either this or the
2135 next option, you may need to edit src/Makefile after compiling to point
2136 DINCLUDE and DLIB to the right places.
2138 You can only use either this option and the following (should
2141 =item --enable-dlmalloc (default: off)
2143 Use Doug Lea's malloc - which is good for a production version
2144 See L<http://g.oswego.edu/dl/html/malloc.html> for details.
2146 =item --enable-smart-resize (default: on)
2148 Add smart growth/shrink behaviour when changing font size via hot

2150 the screen in a fixed position.
2152 =item --enable-pointer-blank (default: on)
2154 Add support to have the pointer disappear when typing or inactive.
2156 =item --enable-perl (default: off)
2158 Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
2159 manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the files
2160 in F<src/perl-ext/> for the extensions that are installed by default. The
2161 perl interpreter that is used can be specified via the C<PERL> environment
2162 variable when running configure.
2164 =item --with-name=NAME (default: urxvt)
2166 Set the basename for the installed binaries, resulting
2167 in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
2170 =item --with-term=NAME (default: rxvt-unicode)
2172 Change the environmental variable for the terminal to NAME.
2174 =item --with-terminfo=PATH
2176 Change the environmental variable for the path to the terminfo tree to
2181 Use the X Window System (pretty much default, eh?).
2183 =item --with-xpm-includes=DIR
2185 Look for the XPM includes in DIR.
2187 =item --with-xpm-library=DIR
2189 Look for the XPM library in DIR.
2193 Not needed - define via --enable-xpm-background.
