29=item The new selection selects pieces that are too big, how can I select 30=head2 Meta, Features & Commandline Issues
30single words?
31 31
32Yes. For example, if you want to select alphanumeric words, you can use 32=head3 My question isn't answered here, can I ask a human?
33the following resource:

35 URxvt.selection.pattern-0: ([[:word:]]+) 34Before sending me mail, you could go to IRC: C<irc.freenode.net>,
35channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
36interested in learning about new and exciting problems (but not FAQs :).
36 37
37If you click more than twice, the selection will be extended 38=head3 I use Gentoo, and I have a problem...
38more and more.
39 39
40To get a selection that is very similar to the old code, try this pattern: 40There are three big problems with Gentoo Linux: first of all, most if not
41all Gentoo systems are completely broken (missing or mismatched header
42files, broken compiler etc. are just the tip of the iceberg); secondly,
43the Gentoo maintainer thinks it is a good idea to add broken patches to
44the code; and lastly, it should be called Gentoo GNU/Linux.
41 45
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) 46For these reasons, it is impossible to support rxvt-unicode on
47Gentoo. Problems appearing on Gentoo systems will usually simply be
48ignored unless they can be reproduced on non-Gentoo systems.
43 49
44Please also note that the I<LeftClick Shift-LeftClik> combination also 50=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
45selects words like the old code.
46 51
47=item I don't like the new selection/popups/hotkeys/perl, how do I 52Beginning with version 7.3, there is a perl extension that implements a
48change/disable it? 53simple tabbed terminal. It is installed by default, so any of these should
54give you tabs:
49 55
50You can disable the perl extension completely by setting the 56 @@URXVT_NAME@@ -pe tabbed
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53 57
54If you only want to disable specific features, you first have to 58 URxvt.perl-ext-common: default,tabbed
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59 59
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup 60It will also work fine with tabbing functionality of many window managers
61or similar tabbing programs, and its embedding-features allow it to be
62embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
63the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
64(murxvt) terminal as an example embedding application.
61 65
62This will keep the default extensions, but disable the two popup 66=head3 How do I know which rxvt-unicode version I'm using?
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other combination either by setting the B<searchable-scrollback> resource:
66 67
67 URxvt.searchable-scrollback: CM-s 68The version number is displayed with the usage (-h). Also the escape
69sequence C<ESC [ 8 n> sets the window title to the version number. When
70using the @@URXVT_NAME@@c client, the version displayed is that of the
71daemon.
68 72
73=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
74
75Rxvt-unicode tries to obey the rule of not charging you for something you
76don't use. One thing you should try is to configure out all settings that
77you don't need, for example, Xft support is a resource hog by design,
78when used. Compiling it out ensures that no Xft font will be loaded
79accidentally when rxvt-unicode tries to find a font for your characters.
80
81Also, many people (me included) like large windows and even larger
82scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
836 bytes per screen cell. For a 160x?? window this amounts to almost a
84kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
85use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
86rxvt-unicode then uses 8 bytes per screen cell.
87
88=head3 How can I start @@URXVT_NAME@@d in a race-free way?
89
90Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
91display, create the listening socket and then fork.
92
93=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
94
95If you want to start @@URXVT_NAME@@d automatically whenever you run
96@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
97
98 #!/bin/sh
99 @@URXVT_NAME@@c "$@"
100 if [ $? -eq 2 ]; then
101 @@URXVT_NAME@@d -q -o -f
102 @@URXVT_NAME@@c "$@"
103 fi
104
105This tries to create a new terminal, and if fails with exit status 2,
106meaning it couldn't connect to the daemon, it will start the daemon and
107re-run the command. Subsequent invocations of the script will re-use the
108existing daemon.
109
110=head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
111
112The original rxvt and rxvt-unicode always export the variable "COLORTERM",
113so you can check and see if that is set. Note that several programs, JED,
114slrn, Midnight Commander automatically check this variable to decide
115whether or not to use color.
116
117=head3 How do I set the correct, full IP address for the DISPLAY variable?
118
119If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
120insecure mode then it is possible to use the following shell script
121snippets to correctly set the display. If your version of rxvt-unicode
122wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
123the COLORTERM variable can be used to distinguish rxvt-unicode from a
124regular xterm.
125
126Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
127snippets:
128
129 # Bourne/Korn/POSIX family of shells:
130 [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
131 if [ ${TERM:-foo} = xterm ]; then

142=head3 How do I compile the manual pages on my own?
143
144You need to have a recent version of perl installed as F</usr/bin/perl>,
145one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
146F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.

149and its embedding-features allow it to be embedded into other programs,

160 232
161=item I am using Debian GNU/Linux and have a problem... 233Here are four ways to get transparency. B<Do> read the manpage and option
234descriptions for the programs mentioned and rxvt-unicode. Really, do it!
162 235
163The Debian GNU/Linux package of rxvt-unicode in sarge contains large 2361. Use transparent mode:
164patches that considerably change the behaviour of rxvt-unicode. Before
165reporting a bug to the original rxvt-unicode author please download and
166install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
167and try to reproduce the problem. If you cannot, chances are that the
168problems are specific to Debian GNU/Linux, in which case it should be
169reported via the Debian Bug Tracking System (use C<reportbug> to report
170the bug).
171 237
172For other problems that also affect the Debian package, you can and 238 Esetroot wallpaper.jpg
173probably should use the Debian BTS, too, because, after all, it's also a 239 @@URXVT_NAME@@ -tr -tint red -sh 40
174bug in the Debian version and it serves as a reminder for other users that
175might encounter the same issue.
176 240
177=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation? 241That works. If you think it doesn't, you lack transparency and tinting
242support, or you are unable to read.
178 243
179You should build one binary with the default options. F<configure> 2442. Use a simple pixmap and emulate pseudo-transparency. This enables you
180now enables most useful options, and the trend goes to making them 245to use effects other than tinting and shading: Just shade/tint/whatever
181runtime-switchable, too, so there is usually no drawback to enbaling them, 246your picture with gimp or any other tool:
182except higher disk and possibly memory usage. The perl interpreter should
183be enabled, as important functionality (menus, selection, likely more in
184the future) depends on it.
185 247
186You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources 248 convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
187system-wide (except maybe with C<defaults>). This will result in useful 249 @@URXVT_NAME@@ -pixmap "background.jpg;:root"
188behaviour. If your distribution aims at low memory, add an empty
189C<perl-ext-common> resource to the app-defaults file. This will keep the
190perl interpreter disabled until the user enables it.
191 250
192If you can/want build more binaries, I recommend building a minimal 251That works. If you think it doesn't, you lack AfterImage support, or you
193one with C<--disable-everything> (very useful) and a maximal one with 252are unable to read.
194C<--enable-everything> (less useful, it will be very big due to a lot of
195encodings built-in that increase download times and are rarely used).
196 253
197=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? 2543. Use an ARGB visual:
198 255
199Likely not. While I honestly try to make it secure, and am probably not 256 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
200bad at it, I think it is simply unreasonable to expect all of freetype
201+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202secure. Also, rxvt-unicode disables some options when it detects that it
203runs setuid or setgid, which is not nice. Besides, with the embedded perl
204interpreter the possibility for security problems easily multiplies.
205 257
206Elevated privileges are only required for utmp and pty operations on some 258This requires XFT support, and the support of your X-server. If that
207systems (for example, GNU/Linux doesn't need any extra privileges for 259doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
208ptys, but some need it for utmp support). It is planned to mvoe this into 260there yet, no matter what they claim. Rxvt-Unicode contains the necessary
209a forked handler process, but this is not yet done. 261bugfixes and workarounds for Xft and Xlib to make it work, but that
262doesn't mean that your WM has the required kludges in place.
210 263
211So, while setuid/setgid operation is supported and not a problem on your 2644. Use xcompmgr and let it do the job:
212typical single-user-no-other-logins unix desktop, always remember that
213its an awful lot of code, most of which isn't checked for security issues
214regularly.
215 265
216=item When I log-in to another system it tells me about missing terminfo data? 266 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
267 -set _NET_WM_WINDOW_OPACITY 0xc0000000
217 268
218The terminal description used by rxvt-unicode is not as widely available 269Then click on a window you want to make transparent. Replace C<0xc0000000>
219as that for xterm, or even rxvt (for which the same problem often arises). 270by other values to change the degree of opacity. If it doesn't work and
271your server crashes, you got to keep the pieces.
220 272
221The correct solution for this problem is to install the terminfo, this can
222be done like this (with ncurses' infocmp):
223
224 REMOTE=remotesystem.domain
225 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
226
227... or by installing rxvt-unicode normally on the remote system,
228
229If you cannot or do not want to do this, then you can simply set
230C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
231problems arising, which includes wrong keymapping, less and different
232colours and some refresh errors in fullscreen applications. It's a nice
233quick-and-dirty workaround for rare cases, though.
234
235If you always want to do this (and are fine with the consequences) you
236can either recompile rxvt-unicode with the desired TERM value or use a
237resource to set it:
238
239 URxvt.termName: rxvt
240
241If you don't plan to use B<rxvt> (quite common...) you could also replace
242the rxvt terminfo file with the rxvt-unicode one.
243
244=item C<tic> outputs some error when compiling the terminfo entry.
245
246Most likely it's the empty definition for C<enacs=>. Just replace it by
247C<enacs=\E[0@> and try again.
248
249=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
250
251=item I need a termcap file entry.
252
253One reason you might want this is that some distributions or operating
254systems still compile some programs using the long-obsoleted termcap
255library (Fedora Core's bash is one example) and rely on a termcap entry
256for C<rxvt-unicode>.
257
258You could use rxvt's termcap entry with resonable results in many cases.
259You can also create a termcap entry by using terminfo's infocmp program
260like this:
261
262 infocmp -C rxvt-unicode
263
264Or you could use this termcap entry, generated by the command above:

289The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to

292with most other terminals supporting colour). Either add:

306=item Why are the secondary screen-related options not working properly?
307
308Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
309distributions (most notably Debian GNU/Linux) break rxvt-unicode
310by setting C<TERM> to C<rxvt>, which doesn't have these extra
311features. Unfortunately, some of these (most notably, again, Debian
312GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
313file, so you will need to install it on your own (See the question B<When
314I log-in to another system it tells me about missing terminfo data?> on
315how to do this).
316
317=item My numerical keypad acts weird and generates differing output?
318
319Some Debian GNUL/Linux users seem to have this problem, although no
320specific details were reported so far. It is possible that this is caused
321by the wrong C<TERM> setting, although the details of wether and how
322this can happen are unknown, as C<TERM=rxvt> should offer a compatible
323keymap. See the answer to the previous question, and please report if that
324helped.
325
326=item Rxvt-unicode does not seem to understand the selected encoding?
327
328=item Unicode does not seem to work?
329
330If you encounter strange problems like typing an accented character but
331getting two unrelated other characters or similar, or if program output is
332subtly garbled, then you should check your locale settings.
333
334Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
335programs. Often rxvt-unicode is started in the C<C> locale, while the
336login script running within the rxvt-unicode window changes the locale to
337something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
338
339The best thing is to fix your startup environment, as you will likely run
340into other problems. If nothing works you can try this in your .profile.
341
342 printf '\e]701;%s\007' "$LC_CTYPE"
343
344If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
345supported on your systems. Some systems have a C<locale> command which
346displays this (also, C<perl -e0> can be used to check locale settings, as
347it will complain loudly if it cannot set the locale). If it displays something
348like:
349
350 locale: Cannot set LC_CTYPE to default locale: ...
351
352Then the locale you specified is not supported on your system.
353
354If nothing works and you are sure that everything is set correctly then
355you will need to remember a little known fact: Some programs just don't
356support locales :(
357
358=item Why do some characters look so much different than others?
359
360=item How does rxvt-unicode choose fonts?
361
362Most fonts do not contain the full range of Unicode, which is
363fine. Chances are that the font you (or the admin/package maintainer of
364your system/os) have specified does not cover all the characters you want
365to display.
366
367B<rxvt-unicode> makes a best-effort try at finding a replacement
368font. Often the result is fine, but sometimes the chosen font looks
369bad/ugly/wrong. Some fonts have totally strange characters that don't
370resemble the correct glyph at all, and rxvt-unicode lacks the artificial
371intelligence to detect that a specific glyph is wrong: it has to believe
372the font that the characters it claims to contain indeed look correct.
373
374In that case, select a font of your taste and add it to the font list,
375e.g.:
376
377 @@RXVT_NAME@@ -fn basefont,font2,font3...
378
379When rxvt-unicode sees a character, it will first look at the base
380font. If the base font does not contain the character, it will go to the
381next font, and so on. Specifying your own fonts will also speed up this
382search and use less resources within rxvt-unicode and the X-server.
383
384The only limitation is that none of the fonts may be larger than the base
385font, as the base font defines the terminal character cell size, which
386must be the same due to the way terminals work.
387
388=item Why do some chinese characters look so different than others?
389
390This is because there is a difference between script and language --
391rxvt-unicode does not know which language the text that is output is,
392as it only knows the unicode character codes. If rxvt-unicode first
393sees a japanese/chinese character, it might choose a japanese font for
394display. Subsequent japanese characters will use that font. Now, many
395chinese characters aren't represented in japanese fonts, so when the first
396non-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
398chinese characters that are also in the japanese font.
399
400The workaround is easy: just tag a chinese font at the end of your font
401list (see the previous question). The key is to view the font list as
402a preference list: If you expect more japanese, list a japanese font
403first. If you expect more chinese, put a chinese font first.
404
405In the future it might be possible to switch language preferences at
406runtime (the internal data structure has no problem with using different
407fonts for the same character at the same time, but no interface for this
408has been designed yet).
409
410Until then, you might get away with switching fonts at runtime (see L<Can
411I switch the fonts at runtime?> later in this document).

447your input method. For example, if you specified B<OverTheSpot> and
448your input method (e.g. the default input method handling Compose keys)
449does not support this (for instance because it is not visual), then
450rxvt-unicode will continue without an input method.
451
452In this case either do not specify a B<preeditStyle> or specify more than

483 315
484=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
485
486Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
487in your compile environment, or an implementation that implements it,
488wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
489B<wchar_t> is represented as unicode.
490
491As you might have guessed, FreeBSD does neither define this symobl nor
492does it support it. Instead, it uses it's own internal representation of
493B<wchar_t>. This is, of course, completely fine with respect to standards.
494
495However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
496C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
497
498C<__STDC_ISO_10646__> is the only sane way to support multi-language
499apps in an OS, as using a locale-dependent (and non-standardized)
500representation of B<wchar_t> makes it impossible to convert between
501B<wchar_t> (as used by X11 and your applications) and any other encoding
502without implementing OS-specific-wrappers for each and every locale. There
503simply are no APIs to convert B<wchar_t> into anything except the current
504locale encoding.
505
506Some applications (such as the formidable B<mlterm>) work around this
507by carrying their own replacement functions for character set handling
508with them, and either implementing OS-dependent hacks or doing multiple
509conversions (which is slow and unreliable in case the OS implements
510encodings slightly different than the terminal emulator).
511
512The rxvt-unicode author insists that the right way to fix this is in the
513system libraries once and for all, instead of forcing every app to carry
514complete replacements for them :)
515

520
521=item How can I use rxvt-unicode under cygwin?
522
523rxvt-unicode should compile and run out of the box on cygwin, using
524the X11 libraries that come with cygwin. libW11 emulation is no
525longer supported (and makes no sense, either, as it only supported a
526single font). I recommend starting the X-server in C<-multiwindow> or
527C<-rootless> mode instead, which will result in similar look&feel as the
528old libW11 emulation.
529
530At the time of this writing, cygwin didn't seem to support any multi-byte
531encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
532to 8-bit encodings.
533
534=item How does rxvt-unicode determine the encoding to use?
535
536=item Is there an option to switch encodings?
537
538Unlike some other terminals, rxvt-unicode has no encoding switch, and no
539specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
540UTF-8 or any other encodings with respect to terminal I/O.
541
542The reasons is that there exists a perfectly fine mechanism for selecting
543the encoding, doing I/O and (most important) communicating this to all
544applications so everybody agrees on character properties such as width
545and code number. This mechanism is the I<locale>. Applications not using
546that info will have problems (for example, C<xterm> gets the width of
547characters wrong as it uses it's own, locale-independent table under all
548locales).
549
550Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
551programs doing the same (that is, most) will automatically agree in the
552interpretation of characters.
553
554Unfortunately, there is no system-independent way to select locales, nor
555is there a standard on how locale specifiers will look like.
556
557On most systems, the content of the C<LC_CTYPE> environment variable
558contains an arbitrary string which corresponds to an already-installed
559locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
560C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
561(i.e. C<de> or C<german>) are also common.
562
563Rxvt-unicode ignores all other locale categories, and except for
564the encoding, ignores country or language-specific settings,
565i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
566rxvt-unicode.
567
568If you want to use a specific encoding you have to make sure you start
569rxvt-unicode with the correct C<LC_CTYPE> category.
570
571=item Can I switch locales at runtime?
572
573Yes, using an escape sequence. Try something like this, which sets
574rxvt-unicode's idea of C<LC_CTYPE>.
575
576 printf '\e]701;%s\007' ja_JP.SJIS
577
578See also the previous answer.
579
580Sometimes this capability is rather handy when you want to work in
581one 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
583first switches to a locale supported by xjdic and back later:
584
585 printf '\e]701;%s\007' ja_JP.SJIS
586 xjdic -js
587 printf '\e]701;%s\007' de_DE.UTF-8
588
589You can also use xterm's C<luit> program, which usually works fine, except
590for some locales where character width differs between program- and
591rxvt-unicode-locales.
592
593=item Can I switch the fonts at runtime? 316=head3 Can I switch the fonts at runtime?

620
621 URxvt.imlocale: ja_JP.EUC-JP
622
623Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
624use your input method. Please note, however, that you will not be able to
625input characters outside C<EUC-JP> in a normal way then, as your input
626method limits you.
627
628=item Rxvt-unicode crashes when the X Input Method changes or exits.
629
630Unfortunately, this is unavoidable, as the XIM protocol is racy by
631design. Applications can avoid some crashes at the expense of memory
632leaks, and Input Methods can avoid some crashes by careful ordering at
633exit time. B<kinput2> (and derived input methods) generally succeeds,
634while B<SCIM> (or similar input methods) fails. In the end, however,
635crashes cannot be completely avoided even if both sides cooperate.
636
637So the only workaround is not to kill your Input Method Servers.
638
639=item Rxvt-unicode uses gobs of memory, how can I reduce that?
640
641Rxvt-unicode tries to obey the rule of not charging you for something you
642don't use. One thing you should try is to configure out all settings that
643you don't need, for example, Xft support is a resource hog by design,
644when used. Compiling it out ensures that no Xft font will be loaded
645accidentally when rxvt-unicode tries to find a font for your characters.
646
647Also, many people (me included) like large windows and even larger
648scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use

651use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as

424
425=head3 How does rxvt-unicode choose fonts?
426
427Most fonts do not contain the full range of Unicode, which is
428fine. Chances are that the font you (or the admin/package maintainer of
429your system/os) have specified does not cover all the characters you want
430to display.
431
432B<rxvt-unicode> makes a best-effort try at finding a replacement
433font. Often the result is fine, but sometimes the chosen font looks
434bad/ugly/wrong. Some fonts have totally strange characters that don't
435resemble the correct glyph at all, and rxvt-unicode lacks the artificial
436intelligence to detect that a specific glyph is wrong: it has to believe
437the font that the characters it claims to contain indeed look correct.
438
439In that case, select a font of your taste and add it to the font list,
440e.g.:
441
442 @@URXVT_NAME@@ -fn basefont,font2,font3...
443
444When rxvt-unicode sees a character, it will first look at the base
445font. If the base font does not contain the character, it will go to the
446next font, and so on. Specifying your own fonts will also speed up this
447search and use less resources within rxvt-unicode and the X-server.
448
449The only limitation is that none of the fonts may be larger than the base
450font, as the base font defines the terminal character cell size, which
451must be the same due to the way terminals work.
452
453=head3 Why do some chinese characters look so different than others?
454
455This is because there is a difference between script and language --
456rxvt-unicode does not know which language the text that is output is,
457as it only knows the unicode character codes. If rxvt-unicode first
458sees a japanese/chinese character, it might choose a japanese font for
459display. Subsequent japanese characters will use that font. Now, many
460chinese characters aren't represented in japanese fonts, so when the first
461non-japanese character comes up, rxvt-unicode will look for a chinese font
462-- unfortunately at this point, it will still use the japanese font for
463chinese characters that are also in the japanese font.
464
465The workaround is easy: just tag a chinese font at the end of your font
466list (see the previous question). The key is to view the font list as
467a preference list: If you expect more japanese, list a japanese font
468first. If you expect more chinese, put a chinese font first.
469
470In the future it might be possible to switch language preferences at
471runtime (the internal data structure has no problem with using different
472fonts for the same character at the same time, but no interface for this
473has been designed yet).
474
475Until then, you might get away with switching fonts at runtime (see L<Can
476I switch the fonts at runtime?> later in this document).

486
487=head3 The new selection selects pieces that are too big, how can I select single words?
488
489If you want to select e.g. alphanumeric words, you can use the following
490setting:
491
492 URxvt.selection.pattern-0: ([[:word:]]+)
493
494If you click more than twice, the selection will be extended
495more and more.
496
497To get a selection that is very similar to the old code, try this pattern:
498
499 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
500
501Please also note that the I<LeftClick Shift-LeftClick> combination also
502selects words like the old code.
503
504=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
505
506You can disable the perl extension completely by setting the
507B<perl-ext-common> resource to the empty string, which also keeps
508rxvt-unicode from initialising perl, saving memory.
509
510If you only want to disable specific features, you first have to
511identify which perl extension is responsible. For this, read the section
512B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
513example, to disable the B<selection-popup> and B<option-popup>, specify
514this B<perl-ext-common> resource:
515
516 URxvt.perl-ext-common: default,-selection-popup,-option-popup
517
518This will keep the default extensions, but disable the two popup
519extensions. Some extensions can also be configured, for example,
520scrollback search mode is triggered by B<M-s>. You can move it to any
521other combination either by setting the B<searchable-scrollback> resource:

528
529=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
530
531These are caused by the C<readline> perl extension. Under normal
532circumstances, it will move your cursor around when you click into the
533line that contains it. It tries hard not to do this at the wrong moment,
534but when running a program that doesn't parse cursor movements or in some
535cases during rlogin sessions, it fails to detect this properly.
536
537You can permanently switch this feature off by disabling the C<readline>
538extension:
539
540 URxvt.perl-ext-common: default,-readline
541
542=head3 My numerical keypad acts weird and generates differing output?
543
544Some Debian GNUL/Linux users seem to have this problem, although no
545specific details were reported so far. It is possible that this is caused
546by the wrong C<TERM> setting, although the details of whether and how
547this can happen are unknown, as C<TERM=rxvt> should offer a compatible
548keymap. See the answer to the previous question, and please report if that
549helped.
550
551=head3 My Compose (Multi_key) key is no longer working.
552
553The most common causes for this are that either your locale is not set
554correctly, or you specified a B<preeditStyle> that is not supported by
555your input method. For example, if you specified B<OverTheSpot> and
556your input method (e.g. the default input method handling Compose keys)
557does not support this (for instance because it is not visual), then
558rxvt-unicode will continue without an input method.
559
560In this case either do not specify a B<preeditStyle> or specify more than
561one pre-edit style, such as B<OverTheSpot,Root,None>.
562
563If it still doesn't work, then maybe your input method doesn't support
564compose sequences - to fall back to the built-in one, make sure you don't
565specify an input method via C<-im> or C<XMODIFIERS>.
566
567=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
568
569Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
570international keyboards) or simply use ISO 14755 support to your
571advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
572codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
573character and so on.
574
575=head3 Mouse cut/paste suddenly no longer works.
576
577Make sure that mouse reporting is actually turned off since killing

580quick check is to see if cut/paste works when the Alt or Shift keys are
581depressed.

797and other stuff, which looks quite good with Bitstream Vera anti-aliased.
798
799Terminus is a quite bad font (many very wrong glyphs), but for most of my
800purposes, it works, and gives a different look, as my normal (Non-bold)
801font is already bold, and I want to see a difference between bold and
802normal fonts.
803
804Please note that I used the C<urxvt> instance name and not the C<URxvt>
805class name. That is because I use different configs for different purposes,
806for example, my IRC window is started with C<-name IRC>, and uses these
807defaults:
808
809 IRC*title: IRC
810 IRC*geometry: 87x12+535+542
811 IRC*saveLines: 0
812 IRC*mapAlert: true
813 IRC*font: suxuseuro
814 IRC*boldFont: suxuseuro
815 IRC*colorBD: white
816 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
817 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
818
819C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
820sizes. C<suxuseuro> allows me to keep an eye (and actually read)
821stuff while keeping a very small window. If somebody pastes something
822complicated (e.g. japanese), I temporarily switch to a larger font.
823
824The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
825C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
826file for different hosts, for example, on ym main desktop, I use:
827
828 URxvt.keysym.C-M-q: command:\033[3;5;5t
829 URxvt.keysym.C-M-y: command:\033[3;5;606t
830 URxvt.keysym.C-M-e: command:\033[3;1605;5t
831 URxvt.keysym.C-M-c: command:\033[3;1605;606t
832 URxvt.keysym.C-M-p: perl:test
833
834The first for keysym definitions allow me to quickly bring some windows
835in the layout I like most. Ion users might start laughing but will stop
836immediately when I tell them that I use my own Fvwm2 module for much the
837same effect as Ion provides, and I only very rarely use the above key
838combinations :->
839
840=head3 Why doesn't rxvt-unicode read my resources?
841
842Well, why, indeed? It does, in a way very similar to other X
843applications. Most importantly, this means that if you or your OS loads
844resources into the X display (the right way to do it), rxvt-unicode will
845ignore any resource files in your home directory. It will only read
846F<$HOME/.Xdefaults> when no resources are attached to the display.
847
848If you have or use an F<$HOME/.Xresources> file, chances are that
849resources are loaded into your X-server. In this case, you have to
850re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
851
852Also consider the form resources have to use:
853
854 URxvt.resource: value
855
856If you want to use another form (there are lots of different ways of
857specifying resources), make sure you understand whether and why it
858works. If unsure, use the form above.
859
860=head3 When I log-in to another system it tells me about missing terminfo data?
861
862The terminal description used by rxvt-unicode is not as widely available
863as that for xterm, or even rxvt (for which the same problem often arises).
864
865The correct solution for this problem is to install the terminfo, this can
866be done by simply installing rxvt-unicode on the remote system as well
867(in case you have a nice package manager ready), or you can install the
868terminfo database manually like this (with ncurses infocmp. works as
869user and root):
870
871 REMOTE=remotesystem.domain
872 infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
873
874One some systems you might need to set C<$TERMINFO> to the full path of
875F<$HOME/.terminfo> for this to work.
876
877If you cannot or do not want to do this, then you can simply set
878C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
879problems arising, which includes wrong keymapping, less and different
880colours and some refresh errors in fullscreen applications. It's a nice
881quick-and-dirty workaround for rare cases, though.
882
883If you always want to do this (and are fine with the consequences) you
884can either recompile rxvt-unicode with the desired TERM value or use a
885resource to set it:
886
887 URxvt.termName: rxvt
888
889If you don't plan to use B<rxvt> (quite common...) you could also replace
890the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
891
892=head3 nano fails with "Error opening terminal: rxvt-unicode"
893
894This exceptionally confusing and useless error message is printed by nano
895when it can't find the terminfo database. Nothing is wrong with your
896terminal, read the previous answer for a solution.
897
898=head3 C<tic> outputs some error when compiling the terminfo entry.
899
900Most likely it's the empty definition for C<enacs=>. Just replace it by
901C<enacs=\E[0@> and try again.
902
903=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
904
905See next entry.
906
907=head3 I need a termcap file entry.
908
909One reason you might want this is that some distributions or operating
910systems still compile some programs using the long-obsoleted termcap
911library (Fedora Core's bash is one example) and rely on a termcap entry
912for C<rxvt-unicode>.
913
914You could use rxvt's termcap entry with reasonable results in many cases.
915You can also create a termcap entry by using terminfo's infocmp program
916like this:
917
918 infocmp -C rxvt-unicode
919
920Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap,
921generated by the command above.
922
923=head3 Why does C<ls> no longer have coloured output?
924
925The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
926decide whether a terminal has colour, but uses its own configuration
927file. Needless to say, C<rxvt-unicode> is not in its default file (among
928with most other terminals supporting colour). Either add:
929
930 TERM rxvt-unicode
931
932to C</etc/DIR_COLORS> or simply add:
933
934 alias ls='ls --color=auto'
935
936to your C<.profile> or C<.bashrc>.
937
938=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
939
940See next entry.
941
942=head3 Why doesn't vim/emacs etc. make use of italic?
943
944See next entry.
945
946=head3 Why are the secondary screen-related options not working properly?
947
948Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
949distributions (most notably Debian GNU/Linux) break rxvt-unicode
950by setting C<TERM> to C<rxvt>, which doesn't have these extra
951features. Unfortunately, some of these (most notably, again, Debian
952GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
953file, so you will need to install it on your own (See the question B<When
954I log-in to another system it tells me about missing terminfo data?> on
955how to do this).
956
957
958=head2 Encoding / Locale / Input Method Issues
959
960=head3 Rxvt-unicode does not seem to understand the selected encoding?
961
962See next entry.
963
964=head3 Unicode does not seem to work?
965
966If you encounter strange problems like typing an accented character but
967getting two unrelated other characters or similar, or if program output is
968subtly garbled, then you should check your locale settings.
969
970Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
971programs running in it. Often rxvt-unicode is started in the C<C> locale,
972while the login script running within the rxvt-unicode window changes the
973locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
974not going to work, and is the most common cause for problems.
975
976The best thing is to fix your startup environment, as you will likely run
977into other problems. If nothing works you can try this in your .profile.
978
979 printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
980
981If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
982supported on your systems. Some systems have a C<locale> command which
983displays this (also, C<perl -e0> can be used to check locale settings, as
984it will complain loudly if it cannot set the locale). If it displays something
985like:
986
987 locale: Cannot set LC_CTYPE to default locale: ...
988
989Then the locale you specified is not supported on your system.
990
991If nothing works and you are sure that everything is set correctly then
992you will need to remember a little known fact: Some programs just don't
993support locales :(
994
995=head3 How does rxvt-unicode determine the encoding to use?
996
997See next entry.
998
999=head3 Is there an option to switch encodings?
1000
1001Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1002specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1003UTF-8 or any other encodings with respect to terminal I/O.
1004
1005The reasons is that there exists a perfectly fine mechanism for selecting
1006the encoding, doing I/O and (most important) communicating this to all
1007applications so everybody agrees on character properties such as width
1008and code number. This mechanism is the I<locale>. Applications not using
1009that info will have problems (for example, C<xterm> gets the width of
1010characters wrong as it uses its own, locale-independent table under all
1011locales).
1012
1013Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1014programs doing the same (that is, most) will automatically agree in the
1015interpretation of characters.
1016
1017Unfortunately, there is no system-independent way to select locales, nor
1018is there a standard on how locale specifiers will look like.
1019
1020On most systems, the content of the C<LC_CTYPE> environment variable
1021contains an arbitrary string which corresponds to an already-installed
1022locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1023C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1024(i.e. C<de> or C<german>) are also common.
1025
1026Rxvt-unicode ignores all other locale categories, and except for
1027the encoding, ignores country or language-specific settings,
1028i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1029rxvt-unicode.
1030
1031If you want to use a specific encoding you have to make sure you start
1032rxvt-unicode with the correct C<LC_CTYPE> category.
1033
1034=head3 Can I switch locales at runtime?
1035
1036Yes, using an escape sequence. Try something like this, which sets
1037rxvt-unicode's idea of C<LC_CTYPE>.
1038
1039 printf '\33]701;%s\007' ja_JP.SJIS
1040
1041See also the previous answer.
1042
1043Sometimes this capability is rather handy when you want to work in
1044one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1045(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1046first switches to a locale supported by xjdic and back later:
1047
1048 printf '\33]701;%s\007' ja_JP.SJIS
1049 xjdic -js
1050 printf '\33]701;%s\007' de_DE.UTF-8
1051
1052You can also use xterm's C<luit> program, which usually works fine, except
1053for some locales where character width differs between program- and
1054rxvt-unicode-locales.
1055
1056=head3 I have problems getting my input method working.
1057
1058Try a search engine, as this is slightly different for every input method server.
1059
1060Here is a checklist:
1061
1062=over 4
1063
1064=item - Make sure your locale I<and> the imLocale are supported on your OS.
1065
1066Try C<locale -a> or check the documentation for your OS.
1067
1068=item - Make sure your locale or imLocale matches a locale supported by your XIM.
1069
1070For example, B<kinput2> does not support UTF-8 locales, you should use
1071C<ja_JP.EUC-JP> or equivalent.
1072
1073=item - Make sure your XIM server is actually running.
1074
1075=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1076
1077When you want to use e.g. B<kinput2>, it must be set to
1078C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1079method servers are running with this command:
1080
1081 xprop -root XIM_SERVERS
1082
1083=item
895 1084
896=back 1085=back
897 1086
1087=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1088
1089You can specify separate locales for the input method and the rest of the
1090terminal, using the resource C<imlocale>:
1091
1092 URxvt.imlocale: ja_JP.EUC-JP
1093
1094Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1095use your input method. Please note, however, that, depending on your Xlib
1096version, you may not be able to input characters outside C<EUC-JP> in a
1097normal way then, as your input method limits you.
1098
1099=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1100
1101Unfortunately, this is unavoidable, as the XIM protocol is racy by
1102design. Applications can avoid some crashes at the expense of memory
1103leaks, and Input Methods can avoid some crashes by careful ordering at
1104exit time. B<kinput2> (and derived input methods) generally succeeds,
1105while B<SCIM> (or similar input methods) fails. In the end, however,
1106crashes cannot be completely avoided even if both sides cooperate.
1107
1108So the only workaround is not to kill your Input Method Servers.
1109
1110
1111=head2 Operating Systems / Package Maintaining
1112
1113=head3 I am using Debian GNU/Linux and have a problem...
1114
1115The Debian GNU/Linux package of rxvt-unicode in sarge contains large
1116patches that considerably change the behaviour of rxvt-unicode (but
1117unfortunately this notice has been removed). Before reporting a bug to
1118the original rxvt-unicode author please download and install the genuine
1119version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
1120the problem. If you cannot, chances are that the problems are specific to
1121Debian GNU/Linux, in which case it should be reported via the Debian Bug
1122Tracking System (use C<reportbug> to report the bug).
1123
1124For other problems that also affect the Debian package, you can and
1125probably should use the Debian BTS, too, because, after all, it's also a
1126bug in the Debian version and it serves as a reminder for other users that
1127might encounter the same issue.
1128
1129=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1130
1131You should build one binary with the default options. F<configure>
1132now enables most useful options, and the trend goes to making them
1133runtime-switchable, too, so there is usually no drawback to enabling them,
1134except higher disk and possibly memory usage. The perl interpreter should
1135be enabled, as important functionality (menus, selection, likely more in
1136the future) depends on it.
1137
1138You should not overwrite the C<perl-ext-common> and C<perl-ext> resources
1139system-wide (except maybe with C<defaults>). This will result in useful
1140behaviour. If your distribution aims at low memory, add an empty
1141C<perl-ext-common> resource to the app-defaults file. This will keep the
1142perl interpreter disabled until the user enables it.
1143
1144If you can/want build more binaries, I recommend building a minimal
1145one with C<--disable-everything> (very useful) and a maximal one with
1146C<--enable-everything> (less useful, it will be very big due to a lot of
1147encodings built-in that increase download times and are rarely used).
1148
1149=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1150
1151It should be, starting with release 7.1. You are encouraged to properly
1152install urxvt with privileges necessary for your OS now.
1153
1154When rxvt-unicode detects that it runs setuid or setgid, it will fork
1155into a helper process for privileged operations (pty handling on some
1156systems, utmp/wtmp/lastlog handling on others) and drop privileges
1157immediately. This is much safer than most other terminals that keep
1158privileges while running (but is more relevant to urxvt, as it contains
1159things as perl interpreters, which might be "helpful" to attackers).
1160
1161This forking is done as the very first within main(), which is very early
1162and reduces possible bugs to initialisation code run before main(), or
1163things like the dynamic loader of your system, which should result in very
1164little risk.
1165
1166=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1167
1168Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1169in your compile environment, or an implementation that implements it,
1170whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1171B<wchar_t> is represented as unicode.
1172
1173As you might have guessed, FreeBSD does neither define this symbol nor
1174does it support it. Instead, it uses its own internal representation of
1175B<wchar_t>. This is, of course, completely fine with respect to standards.
1176
1177However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1178C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>).
1179
1180C<__STDC_ISO_10646__> is the only sane way to support multi-language
1181apps in an OS, as using a locale-dependent (and non-standardized)
1182representation of B<wchar_t> makes it impossible to convert between
1183B<wchar_t> (as used by X11 and your applications) and any other encoding
1184without implementing OS-specific-wrappers for each and every locale. There
1185simply are no APIs to convert B<wchar_t> into anything except the current
1186locale encoding.
1187
1188Some applications (such as the formidable B<mlterm>) work around this
1189by carrying their own replacement functions for character set handling
1190with them, and either implementing OS-dependent hacks or doing multiple
1191conversions (which is slow and unreliable in case the OS implements
1192encodings slightly different than the terminal emulator).
1193
1194The rxvt-unicode author insists that the right way to fix this is in the
1195system libraries once and for all, instead of forcing every app to carry
1196complete replacements for them :)
1197
1198=head3 How can I use rxvt-unicode under cygwin?
1199
1200rxvt-unicode should compile and run out of the box on cygwin, using
1201the X11 libraries that come with cygwin. libW11 emulation is no
1202longer supported (and makes no sense, either, as it only supported a
1203single font). I recommend starting the X-server in C<-multiwindow> or
1204C<-rootless> mode instead, which will result in similar look&feel as the
1205old libW11 emulation.
1206
1207At the time of this writing, cygwin didn't seem to support any multi-byte
1208encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
1209to 8-bit encodings.
1210
1211=head3 Character widths are not correct.
1212
1213urxvt uses the system wcwidth function to know the information about
1214the width of characters, so on systems with incorrect locale data you
1215will likely get bad results. Two notorious examples are Solaris 9,
1216where single-width characters like U+2514 are reported as double-width,
1217and Darwin 8, where combining chars are reported having width 1.
1218
1219The solution is to upgrade your system or switch to a better one. A
1220possibly working workaround is to use a wcwidth implementation like
1221
1222http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
