161     <p>Before sending me mail, you could go to IRC: <code>irc.freenode.net</code>,
162     channel <code>#rxvt-unicode</code> has some rxvt-unicode enthusiasts that might be
163     interested in learning about new and exciting problems (but not FAQs :).</p>

166     <h3><a name="does_it_support_tabs__can_i_have_a_tabbed_rxvtunicode">Does it support tabs, can I have a tabbed rxvt-unicode?</a></h3>
167     <p>Beginning with version 7.3, there is a perl extension that implements a
168     simple tabbed terminal. It is installed by default, so any of these should
169     give you tabs:</p>
170 root 1.42 <pre>
171 root 1.61 urxvt -pe tabbed</pre>
172 root 1.42 <pre>
173 root 1.60 URxvt.perl-ext-common: default,tabbed</pre>
174     <p>It will also work fine with tabbing functionality of many window managers
175     or similar tabbing programs, and its embedding-features allow it to be
176     embedded into other programs, as witnessed by <em>doc/rxvt-tabbed</em> or
177     the upcoming <code>Gtk2::URxvt</code> perl module, which features a tabbed urxvt
178     (murxvt) terminal as an example embedding application.</p>
179     <p>
180     </p>
181     <h3><a name="how_do_i_know_which_rxvtunicode_version_i_m_using">How do I know which rxvt-unicode version I'm using?</a></h3>
182     <p>The version number is displayed with the usage (-h). Also the escape
183     sequence <code>ESC [ 8 n</code> sets the window title to the version number. When
184 root 1.61 using the urxvtc client, the version displayed is that of the
185 root 1.60 daemon.</p>
186 root 1.57 <p>

188 root 1.60 <h3><a name="rxvtunicode_uses_gobs_of_memory__how_can_i_reduce_that">Rxvt-unicode uses gobs of memory, how can I reduce that?</a></h3>
189     <p>Rxvt-unicode tries to obey the rule of not charging you for something you
190     don't use. One thing you should try is to configure out all settings that
191     you don't need, for example, Xft support is a resource hog by design,
192     when used. Compiling it out ensures that no Xft font will be loaded
193     accidentally when rxvt-unicode tries to find a font for your characters.</p>
194     <p>Also, many people (me included) like large windows and even larger
195     scrollback buffers: Without <code>--enable-unicode3</code>, rxvt-unicode will use
196     6 bytes per screen cell. For a 160x?? window this amounts to almost a
197     kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
198     use 10 Megabytes of memory. With <code>--enable-unicode3</code> it gets worse, as
199     rxvt-unicode then uses 8 bytes per screen cell.</p>

208 root 1.63 <p>The original rxvt and rxvt-unicode always export the variable ``COLORTERM'',
209     so you can check and see if that is set. Note that several programs, JED,
210     slrn, Midnight Commander automatically check this variable to decide
211     whether or not to use color.</p>

215     <p>If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
216     insecure mode then it is possible to use the following shell script
217     snippets to correctly set the display. If your version of rxvt-unicode
218     wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
219     the COLORTERM variable can be used to distinguish rxvt-unicode from a
220     regular xterm.</p>

245 root 1.57 <p>I often get asked about this, and I think, no, they didn't cause extra
246 root 1.28 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
247     that the urxvt binary is larger (due to some encoding tables always being
248     compiled in), but it actually uses less memory (RSS) after startup. Even
249     with <code>--disable-everything</code>, this comparison is a bit unfair, as many
250     features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
251 root 1.57 already in use in this mode.</p>

255     188985 9048 66616 18222 1788 urxvt --disable-everything</pre>
256 root 1.64 <p>When you <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (which <em>is</em> unfair, as this involves xft
257 root 1.28 and full locale/XIM support which are quite bloaty inside libX11 and my
258     libc), the two diverge, but not unreasnobaly so.</p>
259     <pre>
260     text data bss drs rss filename
261     163431 2152 24 20123 2060 rxvt --enable-everything
262     1035683 49680 66648 29096 3680 urxvt --enable-everything</pre>
263     <p>The very large size of the text section is explained by the east-asian
264     encoding tables, which, if unused, take up disk space but nothing else
265     and can be compiled out unless you rely on X11 core fonts that use those
266     encodings. The BSS size comes from the 64k emergency buffer that my c++
267     compiler allocates (but of course doesn't use unless you are out of
268     memory). Also, using an xft font instead of a core font immediately adds a
269     few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
270     not used.</p>
271     <p>Of course, due to every character using two or four bytes instead of one,

283 root 1.57 <p>Is this a question? :) It comes up very often. The simple answer is: I had
284 root 1.28 to write it, and C++ allowed me to write and maintain it in a fraction
285     of the time and effort (which is a scarce resource for me). Put even
286 root 1.57 shorter: It simply wouldn't exist without C++.</p>
287 root 1.28 <p>My personal stance on this is that C++ is less portable than C, but in
288     the case of rxvt-unicode this hardly matters, as its portability limits
289     are defined by things like X11, pseudo terminals, locale support and unix
290     domain sockets, which are all less portable than C++ itself.</p>
291     <p>Regarding the bloat, see the above question: It's easy to write programs
292     in C that use gobs of memory, an certainly possible to write programs in
293     C++ that don't. C++ also often comes with large libraries, but this is
294     not necessarily the case with GCC. Here is what rxvt links against on my
295     system with a minimal config:</p>

315     <h3><a name="i_can_t_get_transparency_working__what_am_i_doing_wrong">I can't get transparency working, what am I doing wrong?</a></h3>
316     <p>First of all, transparency isn't officially supported in rxvt-unicode, so
317     you are mostly on your own. Do not bug the author about it (but you may
318     bug everybody else). Also, if you can't get it working consider it a rite
319     of passage: ... and you failed.</p>
320     <p>Here are four ways to get transparency. <strong>Do</strong> read the manpage and option
321     descriptions for the programs mentioned and rxvt-unicode. Really, do it!</p>
322     <p>1. Use inheritPixmap:</p>
323     <pre>
324     Esetroot wallpaper.jpg
325 root 1.61 urxvt -ip -tint red -sh 40</pre>
326 root 1.60 <p>That works. If you think it doesn't, you lack transparency and tinting
327     support, or you are unable to read.</p>
328     <p>2. Use a simple pixmap and emulate pseudo-transparency. This enables you
329     to use effects other than tinting and shading: Just shade/tint/whatever
330     your picture with gimp or any other tool:</p>
331     <pre>
332     convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
333 root 1.61 urxvt -pixmap background.xpm -pe automove-background</pre>
334 root 1.60 <p>That works. If you think it doesn't, you lack XPM and Perl support, or you
335     are unable to read.</p>
336     <p>3. Use an ARGB visual:</p>
337 root 1.52 <pre>
338 root 1.61 urxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc</pre>
339 root 1.60 <p>This requires XFT support, and the support of your X-server. If that
340     doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
341     there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
342     bugfixes and workarounds for Xft and Xlib to make it work, but that
343     doesn't mean that your WM has the required kludges in place.</p>
344     <p>4. Use xcompmgr and let it do the job:</p>
345 root 1.52 <pre>
346 root 1.60 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
347     -set _NET_WM_WINDOW_OPACITY 0xc0000000</pre>
348     <p>Then click on a window you want to make transparent. Replace <code>0xc0000000</code>
349     by other values to change the degree of opacity. If it doesn't work and
350     your server crashes, you got to keep the pieces.</p>

353 root 1.60 <h3><a name="why_do_some_chinese_characters_look_so_different_than_others">Why do some chinese characters look so different than others?</a></h3>
354     <p>This is because there is a difference between script and language --
355     rxvt-unicode does not know which language the text that is output is,
356     as it only knows the unicode character codes. If rxvt-unicode first
357     sees a japanese/chinese character, it might choose a japanese font for
358     display. Subsequent japanese characters will use that font. Now, many
359     chinese characters aren't represented in japanese fonts, so when the first
360     non-japanese character comes up, rxvt-unicode will look for a chinese font
361     -- unfortunately at this point, it will still use the japanese font for
362     chinese characters that are also in the japanese font.</p>
363     <p>The workaround is easy: just tag a chinese font at the end of your font
364     list (see the previous question). The key is to view the font list as
365     a preference list: If you expect more japanese, list a japanese font
366     first. If you expect more chinese, put a chinese font first.</p>
367     <p>In the future it might be possible to switch language preferences at
368     runtime (the internal data structure has no problem with using different
369     fonts for the same character at the same time, but no interface for this
370     has been designed yet).</p>
371     <p>Until then, you might get away with switching fonts at runtime (see <a href="#can_i_switch_the_fonts_at_runtime">Can I switch the fonts at runtime?</a> later in this document).</p>

373     </p>
374 root 1.60 <h3><a name="why_does_rxvtunicode_sometimes_leave_pixel_droppings">Why does rxvt-unicode sometimes leave pixel droppings?</a></h3>
375     <p>Most fonts were not designed for terminal use, which means that character
376     size varies a lot. A font that is otherwise fine for terminal use might
377     contain some characters that are simply too wide. Rxvt-unicode will avoid
378     these characters. For characters that are just ``a bit'' too wide a special
379     ``careful'' rendering mode is used that redraws adjacent characters.</p>
380     <p>All of this requires that fonts do not lie about character sizes,
381     however: Xft fonts often draw glyphs larger than their acclaimed bounding
382     box, and rxvt-unicode has no way of detecting this (the correct way is to
383     ask for the character bounding box, which unfortunately is wrong in these
384     cases).</p>
385     <p>It's not clear (to me at least), wether this is a bug in Xft, freetype,
386     or the respective font. If you encounter this problem you might try using
387     the <code>-lsp</code> option to give the font more height. If that doesn't work, you
388     might be forced to use a different font.</p>
389     <p>All of this is not a problem when using X11 core fonts, as their bounding
390     box data is correct.</p>

396     make sure you have specified colours for italic and bold, as otherwise
397     rxvt-unicode might use reverse video to simulate the effect:</p>

404     <p>For some unexplainable reason, some rare programs assume a very weird
405     colour palette when confronted with a terminal with more than the standard
406     8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
407     these programs not to assume non-ISO colours without very good reasons.</p>
408     <p>In the meantime, you can either edit your <code>rxvt-unicode</code> terminfo
409     definition to only claim 8 colour support or use <code>TERM=rxvt</code>, which will
410     fix colours but keep you from using other rxvt-unicode features.</p>

413     <h3><a name="can_i_switch_the_fonts_at_runtime">Can I switch the fonts at runtime?</a></h3>

416     <pre>
417     printf '\e]50;%s\007' &quot;9x15bold,xft:Kochi Gothic&quot;</pre>
418     <p>This is useful if you e.g. work primarily with japanese (and prefer a

435     <p>Yes, the most obvious way to speed it up is to avoid Xft entirely, as
436     it is simply slow. If you still want Xft fonts you might try to disable
437     antialiasing (by appending <code>:antialias=false</code>), which saves lots of
438     memory and also speeds up rendering considerably.</p>

443     fall back to it's default font search list it will prefer X11 core
444     fonts, because they are small and fast, and then use Xft fonts. It has
445     antialiasing disabled for most of them, because the author thinks they

515     =head3 How does rxvt-unicode choose fonts?</pre>
516     <pre>
517    
518     Most fonts do not contain the full range of Unicode, which is
519     fine. Chances are that the font you (or the admin/package maintainer of
520     your system/os) have specified does not cover all the characters you want
521     to display.</pre>
522     <pre>
523    
524     B&lt;rxvt-unicode&gt; makes a best-effort try at finding a replacement
525     font. Often the result is fine, but sometimes the chosen font looks
526     bad/ugly/wrong. Some fonts have totally strange characters that don't
527     resemble the correct glyph at all, and rxvt-unicode lacks the artificial
528     intelligence to detect that a specific glyph is wrong: it has to believe
529     the font that the characters it claims to contain indeed look correct.</pre>
530     <pre>
531    
532     In that case, select a font of your taste and add it to the font list,
533     e.g.:</pre>
534     <pre>
535    
536 root 1.61 urxvt -fn basefont,font2,font3...</pre>
537 root 1.60 <pre>
538    
539     When rxvt-unicode sees a character, it will first look at the base
540     font. If the base font does not contain the character, it will go to the
541     next font, and so on. Specifying your own fonts will also speed up this
542     search and use less resources within rxvt-unicode and the X-server.</pre>
543     <pre>
544    
545     The only limitation is that none of the fonts may be larger than the base
546     font, as the base font defines the terminal character cell size, which
547     must be the same due to the way terminals work.</pre>

638     <h3><a name="what_s_with_the_strange_backspace_delete_key_behaviour">What's with the strange Backspace/Delete key behaviour?</a></h3>
639     <p>Assuming that the physical Backspace key corresponds to the
640     BackSpace keysym (not likely for Linux ... see the following
641     question) there are two standard values that can be used for
642     Backspace: <code>^H</code> and <code>^?</code>.</p>
643     <p>Historically, either value is correct, but rxvt-unicode adopts the debian
644     policy of using <code>^?</code> when unsure, because it's the one only only correct
645     choice :).</p>
646     <p>Rxvt-unicode tries to inherit the current stty settings and uses the value
647     of `erase' to guess the value for backspace. If rxvt-unicode wasn't
648     started from a terminal (say, from a menu or by remote shell), then the
649     system value of `erase', which corresponds to CERASE in &lt;termios.h&gt;, will
650     be used (which may not be the same as your stty setting).</p>
651     <p>For starting a new rxvt-unicode:</p>
652     <pre>
653     # use Backspace = ^H
654     $ stty erase ^H
655 root 1.61 $ urxvt</pre>
656 root 1.60 <pre>
657     # use Backspace = ^?
658     $ stty erase ^?
659 root 1.61 $ urxvt</pre>
660 root 1.60 <p>Toggle with <code>ESC [ 36 h</code> / <code>ESC [ 36 l</code>.</p>
661     <p>For an existing rxvt-unicode:</p>
662     <pre>
663     # use Backspace = ^H
664     $ stty erase ^H
665     $ echo -n &quot;^[[36h&quot;</pre>
666     <pre>
667     # use Backspace = ^?
668     $ stty erase ^?
669     $ echo -n &quot;^[[36l&quot;</pre>
670     <p>This helps satisfy some of the Backspace discrepancies that occur, but
671     if you use Backspace = <code>^H</code>, make sure that the termcap/terminfo value
672     properly reflects that.</p>
673     <p>The Delete key is a another casualty of the ill-defined Backspace problem.
674     To avoid confusion between the Backspace and Delete keys, the Delete
675     key has been assigned an escape sequence to match the vt100 for Execute
676     (<code>ESC [ 3 ~</code>) and is in the supplied termcap/terminfo.</p>
677     <p>Some other Backspace problems:</p>
678     <p>some editors use termcap/terminfo,
679     some editors (vim I'm told) expect Backspace = ^H,
680     GNU Emacs (and Emacs-like editors) use ^H for help.</p>
681     <p>Perhaps someday this will all be resolved in a consistent manner.</p>

884 root 1.1 <p>The reasons is that there exists a perfectly fine mechanism for selecting

887     and code number. This mechanism is the <em>locale</em>. Applications not using
888     that info will have problems (for example, <code>xterm</code> gets the width of
889     characters wrong as it uses it's own, locale-independent table under all
890     locales).</p>
891 root 1.1 <p>Rxvt-unicode uses the <code>LC_CTYPE</code> locale category to select encoding. All

894     <p>Unfortunately, there is no system-independent way to select locales, nor
895     is there a standard on how locale specifiers will look like.</p>
896     <p>On most systems, the content of the <code>LC_CTYPE</code> environment variable
897     contains an arbitrary string which corresponds to an already-installed
898     locale. Common names for locales are <code>en_US.UTF-8</code>, <code>de_DE.ISO-8859-15</code>,
899     <code>ja_JP.EUC-JP</code>, i.e. <code>language_country.encoding</code>, but other forms

901     <p>Rxvt-unicode ignores all other locale categories, and except for
902     the encoding, ignores country or language-specific settings,
903 root 1.11 i.e. <code>de_DE.UTF-8</code> and <code>ja_JP.UTF-8</code> are the normally same to

940     <p>Unfortunately, this is unavoidable, as the XIM protocol is racy by
941     design. Applications can avoid some crashes at the expense of memory
942     leaks, and Input Methods can avoid some crashes by careful ordering at
943     exit time. <strong>kinput2</strong> (and derived input methods) generally succeeds,
944     while <strong>SCIM</strong> (or similar input methods) fails. In the end, however,
945     crashes cannot be completely avoided even if both sides cooperate.</p>
946     <p>So the only workaround is not to kill your Input Method Servers.</p>

953     <p>The Debian GNU/Linux package of rxvt-unicode in sarge contains large
954     patches that considerably change the behaviour of rxvt-unicode (but
955     unfortunately this notice has been removed). Before reporting a bug to
956     the original rxvt-unicode author please download and install the genuine
957     version (<a href="http://software.schmorp.de#rxvt-unicode">http://software.schmorp.de#rxvt-unicode</a>) and try to reproduce
958     the problem. If you cannot, chances are that the problems are specific to
959     Debian GNU/Linux, in which case it should be reported via the Debian Bug
960     Tracking System (use <code>reportbug</code> to report the bug).</p>
961     <p>For other problems that also affect the Debian package, you can and
962     probably should use the Debian BTS, too, because, after all, it's also a
963     bug in the Debian version and it serves as a reminder for other users that
964     might encounter the same issue.</p>

968     <p>You should build one binary with the default options. <em>configure</em>
969     now enables most useful options, and the trend goes to making them
970     runtime-switchable, too, so there is usually no drawback to enbaling them,
971     except higher disk and possibly memory usage. The perl interpreter should
972     be enabled, as important functionality (menus, selection, likely more in
973     the future) depends on it.</p>
974     <p>You should not overwrite the <code>perl-ext-common</code> snd <code>perl-ext</code> resources
975     system-wide (except maybe with <code>defaults</code>). This will result in useful
976     behaviour. If your distribution aims at low memory, add an empty
977     <code>perl-ext-common</code> resource to the app-defaults file. This will keep the
978     perl interpreter disabled until the user enables it.</p>
979     <p>If you can/want build more binaries, I recommend building a minimal
980     one with <code>--disable-everything</code> (very useful) and a maximal one with
981     <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (less useful, it will be very big due to a lot of
982     encodings built-in that increase download times and are rarely used).</p>

986     <p>It should be, starting with release 7.1. You are encouraged to properly
987     install urxvt with privileges necessary for your OS now.</p>
988     <p>When rxvt-unicode detects that it runs setuid or setgid, it will fork
989     into a helper process for privileged operations (pty handling on some
990     systems, utmp/wtmp/lastlog handling on others) and drop privileges
991     immediately. This is much safer than most other terminals that keep
992     privileges while running (but is more relevant to urxvt, as it contains
993     things as perl interpreters, which might be ``helpful'' to attackers).</p>
994     <p>This forking is done as the very first within main(), which is very early
995     and reduces possible bugs to initialisation code run before main(), or
996     things like the dynamic loader of your system, which should result in very
997     little risk.</p>

1009     <p>Rxvt-unicode requires the symbol <code>__STDC_ISO_10646__</code> to be defined
1010     in your compile environment, or an implementation that implements it,
1011     wether it defines the symbol or not. <code>__STDC_ISO_10646__</code> requires that
1012     <strong>wchar_t</strong> is represented as unicode.</p>
1013     <p>As you might have guessed, FreeBSD does neither define this symobl nor
1014     does it support it. Instead, it uses it's own internal representation of
1015     <strong>wchar_t</strong>. This is, of course, completely fine with respect to standards.</p>
1016     <p>However, that means rxvt-unicode only works in <code>POSIX</code>, <code>ISO-8859-1</code> and
1017     <code>UTF-8</code> locales under FreeBSD (which all use Unicode as <strong>wchar_t</strong>.</p>
1018     <p><code>__STDC_ISO_10646__</code> is the only sane way to support multi-language
1019     apps in an OS, as using a locale-dependent (and non-standardized)
1020     representation of <strong>wchar_t</strong> makes it impossible to convert between
1021     <strong>wchar_t</strong> (as used by X11 and your applications) and any other encoding
1022     without implementing OS-specific-wrappers for each and every locale. There
1023     simply are no APIs to convert <strong>wchar_t</strong> into anything except the current
1024     locale encoding.</p>
1025     <p>Some applications (such as the formidable <strong>mlterm</strong>) work around this
1026     by carrying their own replacement functions for character set handling
1027     with them, and either implementing OS-dependent hacks or doing multiple
1028     conversions (which is slow and unreliable in case the OS implements
1029     encodings slightly different than the terminal emulator).</p>
1030     <p>The rxvt-unicode author insists that the right way to fix this is in the
1031     system libraries once and for all, instead of forcing every app to carry
1032     complete replacements for them :)</p>

1042     the X11 libraries that come with cygwin. libW11 emulation is no

1045     <code>-rootless</code> mode instead, which will result in similar look&amp;feel as the
1046     old libW11 emulation.</p>
1047     <p>At the time of this writing, cygwin didn't seem to support any multi-byte
1048     encodings (you might try <code>LC_CTYPE=C-UTF-8</code>), so you are likely limited
