24 =head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
27 =head2 Meta, Features & Commandline Issues
29 =head3 My question isn't answered here, can I ask a human?
31 Before sending me mail, you could go to IRC: C<irc.freenode.net>,
32 channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
33 interested in learning about new and exciting problems (but not FAQs :).
35 =head3 Does it support tabs, can I have a tabbed rxvt-unicode?
37 Beginning with version 7.3, there is a perl extension that implements a
38 simple tabbed terminal. It is installed by default, so any of these should

43 URxvt.perl-ext-common: default,tabbed
45 It will also work fine with tabbing functionality of many window managers
46 or similar tabbing programs, and its embedding-features allow it to be
47 embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
48 the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
49 (murxvt) terminal as an example embedding application.
51 =head3 How do I know which rxvt-unicode version I'm using?
53 The version number is displayed with the usage (-h). Also the escape
54 sequence C<ESC [ 8 n> sets the window title to the version number. When
55 using the @@URXVT_NAME@@c client, the version displayed is that of the
58 =head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
60 Rxvt-unicode tries to obey the rule of not charging you for something you
61 don't use. One thing you should try is to configure out all settings that
62 you don't need, for example, Xft support is a resource hog by design,
63 when used. Compiling it out ensures that no Xft font will be loaded
64 accidentally when rxvt-unicode tries to find a font for your characters.
66 Also, many people (me included) like large windows and even larger
67 scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
68 6 bytes per screen cell. For a 160x?? window this amounts to almost a
69 kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
70 use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
71 rxvt-unicode then uses 8 bytes per screen cell.
73 =head3 How can I start @@URXVT_NAME@@d in a race-free way?
75 Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
76 display, create the listening socket and then fork.
78 =head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
80 If you want to start @@URXVT_NAME@@d automatically whenever you run
81 @@URXVT_NAME@@c and the daemon isn't running yet, use this script:
86 @@URXVT_NAME@@d -q -o -f
90 This tries to create a new terminal, and if fails with exit status 2,
91 meaning it couldn't connect to the daemon, it will start the daemon and
92 re-run the command. Subsequent invocations of the script will re-use the
95 =head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
97 The original rxvt and rxvt-unicode always export the variable "COLORTERM",
98 so you can check and see if that is set. Note that several programs, JED,
99 slrn, Midnight Commander automatically check this variable to decide
100 whether or not to use color.
102 =head3 How do I set the correct, full IP address for the DISPLAY variable?
104 If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
105 insecure mode then it is possible to use the following shell script
106 snippets to correctly set the display. If your version of rxvt-unicode
107 wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
108 the COLORTERM variable can be used to distinguish rxvt-unicode from a

114 # Bourne/Korn/POSIX family of shells:

116 if [ ${TERM:-foo} = xterm ]; then

122 echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
123 read DISPLAY # set it in our local shell
127 =head3 How do I compile the manual pages on my own?
129 You need to have a recent version of perl installed as F</usr/bin/perl>,
130 one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
131 F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.
133 =head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
135 I often get asked about this, and I think, no, they didn't cause extra
136 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
137 that the urxvt binary is larger (due to some encoding tables always being
138 compiled in), but it actually uses less memory (RSS) after startup. Even
139 with C<--disable-everything>, this comparison is a bit unfair, as many
140 features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
141 already in use in this mode.
143 text data bss drs rss filename
144 98398 1664 24 15695 1824 rxvt --disable-everything
145 188985 9048 66616 18222 1788 urxvt --disable-everything
147 When you C<--enable-everything> (which I<is> unfair, as this involves xft
148 and full locale/XIM support which are quite bloaty inside libX11 and my
149 libc), the two diverge, but not unreasonably so.
151 text data bss drs rss filename
152 163431 2152 24 20123 2060 rxvt --enable-everything
153 1035683 49680 66648 29096 3680 urxvt --enable-everything
155 The very large size of the text section is explained by the east-asian
156 encoding tables, which, if unused, take up disk space but nothing else
157 and can be compiled out unless you rely on X11 core fonts that use those
158 encodings. The BSS size comes from the 64k emergency buffer that my c++
159 compiler allocates (but of course doesn't use unless you are out of
160 memory). Also, using an xft font instead of a core font immediately adds a
161 few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
164 Of course, due to every character using two or four bytes instead of one,
165 a large scrollback buffer will ultimately make rxvt-unicode use more
168 Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
169 still fares rather well. And compared to some monsters like gnome-terminal
170 (21152k + extra 4204k in separate processes) or konsole (22200k + extra
171 43180k in daemons that stay around after exit, plus half a minute of
172 startup time, including the hundreds of warnings it spits out), it fares
175 =head3 Why C++, isn't that unportable/bloated/uncool?
177 Is this a question? :) It comes up very often. The simple answer is: I had
178 to write it, and C++ allowed me to write and maintain it in a fraction
179 of the time and effort (which is a scarce resource for me). Put even
180 shorter: It simply wouldn't exist without C++.
182 My personal stance on this is that C++ is less portable than C, but in
183 the case of rxvt-unicode this hardly matters, as its portability limits
184 are defined by things like X11, pseudo terminals, locale support and unix
185 domain sockets, which are all less portable than C++ itself.
187 Regarding the bloat, see the above question: It's easy to write programs
188 in C that use gobs of memory, an certainly possible to write programs in
189 C++ that don't. C++ also often comes with large libraries, but this is
190 not necessarily the case with GCC. Here is what rxvt links against on my
191 system with a minimal config:
193 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
194 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
195 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
196 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
198 And here is rxvt-unicode:
200 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
201 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
202 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
203 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
204 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
206 No large bloated libraries (of course, none were linked in statically),
207 except maybe libX11 :)
210 =head2 Rendering, Font & Look and Feel Issues
212 =head3 I can't get transparency working, what am I doing wrong?
214 First of all, transparency isn't officially supported in rxvt-unicode, so
215 you are mostly on your own. Do not bug the author about it (but you may
216 bug everybody else). Also, if you can't get it working consider it a rite
217 of passage: ... and you failed.
219 Here are four ways to get transparency. B<Do> read the manpage and option
220 descriptions for the programs mentioned and rxvt-unicode. Really, do it!
222 1. Use inheritPixmap:
224 Esetroot wallpaper.jpg
225 @@URXVT_NAME@@ -ip -tint red -sh 40
227 That works. If you think it doesn't, you lack transparency and tinting
228 support, or you are unable to read.
230 2. Use a simple pixmap and emulate pseudo-transparency. This enables you
231 to use effects other than tinting and shading: Just shade/tint/whatever
232 your picture with gimp or any other tool:
234 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
235 @@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
237 That works. If you think it doesn't, you lack XPM and Perl support, or you
240 3. Use an ARGB visual:
242 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
244 This requires XFT support, and the support of your X-server. If that
245 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
246 there yet, no matter what they claim. Rxvt-Unicode contains the necessary
247 bugfixes and workarounds for Xft and Xlib to make it work, but that
248 doesn't mean that your WM has the required kludges in place.
250 4. Use xcompmgr and let it do the job:
252 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
253 -set _NET_WM_WINDOW_OPACITY 0xc0000000
255 Then click on a window you want to make transparent. Replace C<0xc0000000>
256 by other values to change the degree of opacity. If it doesn't work and
257 your server crashes, you got to keep the pieces.
259 =head3 Why does rxvt-unicode sometimes leave pixel droppings?
261 Most fonts were not designed for terminal use, which means that character
262 size varies a lot. A font that is otherwise fine for terminal use might
263 contain some characters that are simply too wide. Rxvt-unicode will avoid
264 these characters. For characters that are just "a bit" too wide a special
265 "careful" rendering mode is used that redraws adjacent characters.
267 All of this requires that fonts do not lie about character sizes,
268 however: Xft fonts often draw glyphs larger than their acclaimed bounding
269 box, and rxvt-unicode has no way of detecting this (the correct way is to
270 ask for the character bounding box, which unfortunately is wrong in these
273 It's not clear (to me at least), whether this is a bug in Xft, freetype,
274 or the respective font. If you encounter this problem you might try using
275 the C<-lsp> option to give the font more height. If that doesn't work, you
276 might be forced to use a different font.
278 All of this is not a problem when using X11 core fonts, as their bounding
281 =head3 How can I keep rxvt-unicode from using reverse video so much?
283 First of all, make sure you are running with the right terminal settings
284 (C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
285 make sure you have specified colours for italic and bold, as otherwise
286 rxvt-unicode might use reverse video to simulate the effect:
291 =head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
293 For some unexplainable reason, some rare programs assume a very weird
294 colour palette when confronted with a terminal with more than the standard
295 8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
296 these programs not to assume non-ISO colours without very good reasons.
298 In the meantime, you can either edit your C<rxvt-unicode> terminfo
299 definition to only claim 8 colour support or use C<TERM=rxvt>, which will
300 fix colours but keep you from using other rxvt-unicode features.
302 =head3 Can I switch the fonts at runtime?
304 Yes, using an escape sequence. Try something like this, which has the same
305 effect as using the C<-fn> switch, and takes effect immediately:
307 printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
309 This is useful if you e.g. work primarily with japanese (and prefer a
310 japanese font), but you have to switch to chinese temporarily, where
311 japanese fonts would only be in your way.
313 You can think of this as a kind of manual ISO-2022 switching.
315 =head3 Why do italic characters look as if clipped?
317 Many fonts have difficulties with italic characters and hinting. For
318 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
319 Mono> completely fails in its italic face. A workaround might be to
320 enable freetype autohinting, i.e. like this:
322 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
323 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
325 =head3 Can I speed up Xft rendering somehow?
327 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
328 it is simply slow. If you still want Xft fonts you might try to disable
329 antialiasing (by appending C<:antialias=false>), which saves lots of
330 memory and also speeds up rendering considerably.
332 =head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
334 Rxvt-unicode will use whatever you specify as a font. If it needs to
335 fall back to its default font search list it will prefer X11 core
336 fonts, because they are small and fast, and then use Xft fonts. It has
337 antialiasing disabled for most of them, because the author thinks they
340 If you want antialiasing, you have to specify the fonts manually.
342 =head3 What's with this bold/blink stuff?
344 If no bold colour is set via C<colorBD:>, bold will invert text using the
345 standard foreground colour.
347 For the standard background colour, blinking will actually make the
348 text blink when compiled with C<--enable-blinking>. with standard
349 colours. Without C<--enable-blinking>, the blink attribute will be
352 On ANSI colours, bold/blink attributes are used to set high-intensity
353 foreground/background colors.
355 color0-7 are the low-intensity colors.
357 color8-15 are the corresponding high-intensity colors.
359 =head3 I don't like the screen colors. How do I change them?
361 You can change the screen colors at run-time using F<~/.Xdefaults>
362 resources (or as long-options).
364 Here are values that are supposed to resemble a VGA screen,
365 including the murky brown that passes for low-intensity yellow:
367 URxvt.color0: #000000
368 URxvt.color1: #A80000
369 URxvt.color2: #00A800

408 =head3 Why do some characters look so much different than others?
412 =head3 How does rxvt-unicode choose fonts?
414 Most fonts do not contain the full range of Unicode, which is
415 fine. Chances are that the font you (or the admin/package maintainer of
416 your system/os) have specified does not cover all the characters you want
419 B<rxvt-unicode> makes a best-effort try at finding a replacement
420 font. Often the result is fine, but sometimes the chosen font looks
421 bad/ugly/wrong. Some fonts have totally strange characters that don't
422 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
423 intelligence to detect that a specific glyph is wrong: it has to believe
424 the font that the characters it claims to contain indeed look correct.
426 In that case, select a font of your taste and add it to the font list,
429 @@URXVT_NAME@@ -fn basefont,font2,font3...
431 When rxvt-unicode sees a character, it will first look at the base
432 font. If the base font does not contain the character, it will go to the
433 next font, and so on. Specifying your own fonts will also speed up this
434 search and use less resources within rxvt-unicode and the X-server.
436 The only limitation is that none of the fonts may be larger than the base
437 font, as the base font defines the terminal character cell size, which
438 must be the same due to the way terminals work.
440 =head3 Why do some chinese characters look so different than others?
442 This is because there is a difference between script and language --
443 rxvt-unicode does not know which language the text that is output is,
444 as it only knows the unicode character codes. If rxvt-unicode first
445 sees a japanese/chinese character, it might choose a japanese font for
446 display. Subsequent japanese characters will use that font. Now, many
447 chinese characters aren't represented in japanese fonts, so when the first
448 non-japanese character comes up, rxvt-unicode will look for a chinese font
449 -- unfortunately at this point, it will still use the japanese font for
450 chinese characters that are also in the japanese font.
452 The workaround is easy: just tag a chinese font at the end of your font
453 list (see the previous question). The key is to view the font list as
454 a preference list: If you expect more japanese, list a japanese font
455 first. If you expect more chinese, put a chinese font first.
457 In the future it might be possible to switch language preferences at
458 runtime (the internal data structure has no problem with using different
459 fonts for the same character at the same time, but no interface for this
460 has been designed yet).
462 Until then, you might get away with switching fonts at runtime (see L<Can
463 I switch the fonts at runtime?> later in this document).
465 =head2 Keyboard, Mouse & User Interaction
467 =head3 The new selection selects pieces that are too big, how can I select single words?
469 If you want to select e.g. alphanumeric words, you can use the following
472 URxvt.selection.pattern-0: ([[:word:]]+)
474 If you click more than twice, the selection will be extended
477 To get a selection that is very similar to the old code, try this pattern:
479 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
481 Please also note that the I<LeftClick Shift-LeftClik> combination also
482 selects words like the old code.
484 =head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
486 You can disable the perl extension completely by setting the
487 B<perl-ext-common> resource to the empty string, which also keeps
488 rxvt-unicode from initialising perl, saving memory.
490 If you only want to disable specific features, you first have to
491 identify which perl extension is responsible. For this, read the section
492 B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
493 example, to disable the B<selection-popup> and B<option-popup>, specify
494 this B<perl-ext-common> resource:
496 URxvt.perl-ext-common: default,-selection-popup,-option-popup
498 This will keep the default extensions, but disable the two popup
499 extensions. Some extensions can also be configured, for example,
500 scrollback search mode is triggered by B<M-s>. You can move it to any
501 other combination either by setting the B<searchable-scrollback> resource:
503 URxvt.searchable-scrollback: CM-s
505 =head3 The cursor moves when selecting text in the current input line, how do I switch this off?
509 =head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
511 These are caused by the C<readline> perl extension. Under normal
512 circumstances, it will move your cursor around when you click into the
513 line that contains it. It tries hard not to do this at the wrong moment,
514 but when running a program that doesn't parse cursor movements or in some
515 cases during rlogin sessions, it fails to detect this properly.
517 You can permanently switch this feature off by disabling the C<readline>
520 URxvt.perl-ext-common: default,-readline
522 =head3 My numerical keypad acts weird and generates differing output?
524 Some Debian GNUL/Linux users seem to have this problem, although no
525 specific details were reported so far. It is possible that this is caused
526 by the wrong C<TERM> setting, although the details of whether and how
527 this can happen are unknown, as C<TERM=rxvt> should offer a compatible
528 keymap. See the answer to the previous question, and please report if that
531 =head3 My Compose (Multi_key) key is no longer working.
533 The most common causes for this are that either your locale is not set
534 correctly, or you specified a B<preeditStyle> that is not supported by
535 your input method. For example, if you specified B<OverTheSpot> and
536 your input method (e.g. the default input method handling Compose keys)
537 does not support this (for instance because it is not visual), then
538 rxvt-unicode will continue without an input method.
540 In this case either do not specify a B<preeditStyle> or specify more than
541 one pre-edit style, such as B<OverTheSpot,Root,None>.
543 =head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
545 Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
546 international keyboards) or simply use ISO 14755 support to your
547 advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
548 codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
551 =head3 Mouse cut/paste suddenly no longer works.
553 Make sure that mouse reporting is actually turned off since killing
554 some editors prematurely may leave the mouse in mouse report mode. I've
555 heard that tcsh may use mouse reporting unless it otherwise specified. A
556 quick check is to see if cut/paste works when the Alt or Shift keys are
559 =head3 What's with the strange Backspace/Delete key behaviour?
561 Assuming that the physical Backspace key corresponds to the
562 Backspace keysym (not likely for Linux ... see the following
563 question) there are two standard values that can be used for
564 Backspace: C<^H> and C<^?>.
566 Historically, either value is correct, but rxvt-unicode adopts the debian
567 policy of using C<^?> when unsure, because it's the one and only correct
570 Rxvt-unicode tries to inherit the current stty settings and uses the value
571 of `erase' to guess the value for backspace. If rxvt-unicode wasn't
572 started from a terminal (say, from a menu or by remote shell), then the
573 system value of `erase', which corresponds to CERASE in <termios.h>, will
574 be used (which may not be the same as your stty setting).
576 For starting a new rxvt-unicode:
586 Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
588 For an existing rxvt-unicode:
598 This helps satisfy some of the Backspace discrepancies that occur, but
599 if you use Backspace = C<^H>, make sure that the termcap/terminfo value
600 properly reflects that.
602 The Delete key is a another casualty of the ill-defined Backspace problem.
603 To avoid confusion between the Backspace and Delete keys, the Delete
604 key has been assigned an escape sequence to match the vt100 for Execute
605 (C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
607 Some other Backspace problems:
609 some editors use termcap/terminfo,
610 some editors (vim I'm told) expect Backspace = ^H,
611 GNU Emacs (and Emacs-like editors) use ^H for help.
613 Perhaps someday this will all be resolved in a consistent manner.
615 =head3 I don't like the key-bindings. How do I change them?
617 There are some compile-time selections available via configure. Unless
618 you have run "configure" with the C<--disable-resources> option you can
619 use the `keysym' resource to alter the keystrings associated with keysyms.
621 Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
623 URxvt.keysym.Home: \033[1~
624 URxvt.keysym.End: \033[4~

644 See some more examples in the documentation for the B<keysym> resource.
646 =head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How do I make use of them? For example, the Sun Keyboard type 4 has the following map
655 Rather than have rxvt-unicode try to accommodate all the various possible
656 keyboard mappings, it is better to use `xmodmap' to remap the keys as
657 required for your particular machine.
661 =head2 Terminal Configuration
663 =head3 Can I see a typical configuration?
665 The default configuration tries to be xterm-like, which I don't like that
666 much, but it's least surprise to regular users.
668 As a rxvt or rxvt-unicode user, you are practically supposed to invest
669 time into customising your terminal. To get you started, here is the
670 author's .Xdefaults entries, with comments on what they do. It's certainly
671 not I<typical>, but what's typical...
673 URxvt.cutchars: "()*,<>[]{}|'
674 URxvt.print-pipe: cat >/tmp/xxx
676 These are just for testing stuff.
678 URxvt.imLocale: ja_JP.UTF-8
679 URxvt.preeditType: OnTheSpot,None
681 This tells rxvt-unicode to use a special locale when communicating with
682 the X Input Method, and also tells it to only use the OnTheSpot pre-edit
683 type, which requires the C<xim-onthespot> perl extension but rewards me
684 with correct-looking fonts.
686 URxvt.perl-lib: /root/lib/urxvt
687 URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
688 URxvt.selection.pattern-0: ( at .*? line \\d+)
689 URxvt.selection.pattern-1: ^(/[^:]+):\
690 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
691 URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
693 This is my perl configuration. The first two set the perl library
694 directory and also tells urxvt to use a large number of extensions. I
695 develop for myself mostly, so I actually use most of the extensions I
698 The selection stuff mainly makes the selection perl-error-message aware
699 and tells it to convert perl error messages into vi-commands to load the
700 relevant file and go tot he error line number.
702 URxvt.scrollstyle: plain
703 URxvt.secondaryScroll: true
705 As the documentation says: plain is the preferred scrollbar for the
706 author. The C<secondaryScroll> configures urxvt to scroll in full-screen
707 apps, like screen, so lines scrolled out of screen end up in urxvt's
710 URxvt.background: #000000
711 URxvt.foreground: gray90
713 URxvt.colorBD: #ffffff
714 URxvt.cursorColor: #e0e080
715 URxvt.throughColor: #8080f0
716 URxvt.highlightColor: #f0f0f0
718 Some colours. Not sure which ones are being used or even non-defaults, but
719 these are in my .Xdefaults. Most notably, they set foreground/background
720 to light gray/black, and also make sure that the colour 7 matches the
721 default foreground colour.
723 URxvt.underlineColor: yellow
725 Another colour, makes underline lines look different. Sometimes hurts, but
726 is mostly a nice effect.
728 URxvt.geometry: 154x36
729 URxvt.loginShell: false
731 URxvt.utmpInhibit: true
733 Uh, well, should be mostly self-explanatory. By specifying some defaults
734 manually, I can quickly switch them for testing.
736 URxvt.saveLines: 8192
738 A large scrollback buffer is essential. Really.
742 The only case I use it is for my IRC window, which I like to keep
743 iconified till people msg me (which beeps).
745 URxvt.visualBell: true
747 The audible bell is often annoying, especially when in a crowd.
751 Please don't hack my mutt! Ooops...
753 URxvt.pastableTabs: false
755 I once thought this is a great idea.
757 urxvt.font: 9x15bold,\

764 urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
765 urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
767 I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
768 overwhelmed. A special note: the C<9x15bold> mentioned above is actually
769 the version from XFree-3.3, as XFree-4 replaced it by a totally different
770 font (different glyphs for C<;> and many other harmless characters),
771 while the second font is actually the C<9x15bold> from XFree4/XOrg. The
772 bold version has less chars than the medium version, so I use it for rare
773 characters, too. When editing sources with vim, I use italic for comments
774 and other stuff, which looks quite good with Bitstream Vera anti-aliased.
776 Terminus is a quite bad font (many very wrong glyphs), but for most of my
777 purposes, it works, and gives a different look, as my normal (Non-bold)
778 font is already bold, and I want to see a difference between bold and
781 Please note that I used the C<urxvt> instance name and not the C<URxvt>
782 class name. Thats because I use different configs for different purposes,
783 for example, my IRC window is started with C<-name IRC>, and uses these
787 IRC*geometry: 87x12+535+542
791 IRC*boldFont: suxuseuro
793 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
794 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
796 C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
797 sizes. C<suxuseuro> allows me to keep an eye (and actually read)
798 stuff while keeping a very small window. If somebody pastes something
799 complicated (e.g. japanese), I temporarily switch to a larger font.
801 The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
802 C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
803 file for different hosts, for example, on ym main desktop, I use:
805 URxvt.keysym.C-M-q: command:\033[3;5;5t
806 URxvt.keysym.C-M-y: command:\033[3;5;606t
807 URxvt.keysym.C-M-e: command:\033[3;1605;5t
808 URxvt.keysym.C-M-c: command:\033[3;1605;606t
809 URxvt.keysym.C-M-p: perl:test
811 The first for keysym definitions allow me to quickly bring some windows
812 in the layout I like most. Ion users might start laughing but will stop
813 immediately when I tell them that I use my own Fvwm2 module for much the
814 same effect as Ion provides, and I only very rarely use the above key
817 =head3 Why doesn't rxvt-unicode read my resources?
819 Well, why, indeed? It does, in a way very similar to other X
820 applications. Most importantly, this means that if you or your OS loads
821 resources into the X display (the right way to do it), rxvt-unicode will
822 ignore any resource files in your home directory. It will only read
823 F<$HOME/.Xdefaults> when no resources are attached to the display.
825 If you have or use an F<$HOME/.Xresources> file, chances are that
826 resources are loaded into your X-server. In this case, you have to
827 re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
829 Also consider the form resources have to use:
831 URxvt.resource: value
833 If you want to use another form (there are lots of different ways of
834 specifying resources), make sure you understand whether and why it
835 works. If unsure, use the form above.
837 =head3 When I log-in to another system it tells me about missing terminfo data?
839 The terminal description used by rxvt-unicode is not as widely available
840 as that for xterm, or even rxvt (for which the same problem often arises).
842 The correct solution for this problem is to install the terminfo, this can
843 be done like this (with ncurses' infocmp and works as user and admin):
845 REMOTE=remotesystem.domain
846 infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
848 ... or by installing rxvt-unicode normally on the remote system,
850 One some systems you might need to set C<$TERMINFO> to the full path of
851 F<$HOME/.terminfo> for this to work.
853 If you cannot or do not want to do this, then you can simply set
854 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
855 problems arising, which includes wrong keymapping, less and different
856 colours and some refresh errors in fullscreen applications. It's a nice
857 quick-and-dirty workaround for rare cases, though.
859 If you always want to do this (and are fine with the consequences) you
860 can either recompile rxvt-unicode with the desired TERM value or use a
865 If you don't plan to use B<rxvt> (quite common...) you could also replace
866 the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
868 =head3 C<tic> outputs some error when compiling the terminfo entry.
870 Most likely it's the empty definition for C<enacs=>. Just replace it by
871 C<enacs=\E[0@> and try again.
873 =head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
877 =head3 I need a termcap file entry.
879 One reason you might want this is that some distributions or operating
880 systems still compile some programs using the long-obsoleted termcap
881 library (Fedora Core's bash is one example) and rely on a termcap entry
884 You could use rxvt's termcap entry with reasonable results in many cases.
885 You can also create a termcap entry by using terminfo's infocmp program
888 infocmp -C rxvt-unicode
890 Or you could use this termcap entry, generated by the command above:

913 =head3 Why does C<ls> no longer have coloured output?
915 The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
916 decide whether a terminal has colour, but uses its own configuration
917 file. Needless to say, C<rxvt-unicode> is not in its default file (among
918 with most other terminals supporting colour). Either add:
922 to C</etc/DIR_COLORS> or simply add:
924 alias ls='ls --color=auto'
926 to your C<.profile> or C<.bashrc>.
928 =head3 Why doesn't vim/emacs etc. use the 88 colour mode?
932 =head3 Why doesn't vim/emacs etc. make use of italic?
936 =head3 Why are the secondary screen-related options not working properly?
938 Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
939 distributions (most notably Debian GNU/Linux) break rxvt-unicode
940 by setting C<TERM> to C<rxvt>, which doesn't have these extra
941 features. Unfortunately, some of these (most notably, again, Debian
942 GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
943 file, so you will need to install it on your own (See the question B<When
944 I log-in to another system it tells me about missing terminfo data?> on
948 =head2 Encoding / Locale / Input Method Issues
950 =head3 Rxvt-unicode does not seem to understand the selected encoding?
954 =head3 Unicode does not seem to work?
956 If you encounter strange problems like typing an accented character but
957 getting two unrelated other characters or similar, or if program output is
958 subtly garbled, then you should check your locale settings.
960 Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
961 programs running in it. Often rxvt-unicode is started in the C<C> locale,
962 while the login script running within the rxvt-unicode window changes the
963 locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
964 not going to work, and is the most common cause for problems.
966 The best thing is to fix your startup environment, as you will likely run
967 into other problems. If nothing works you can try this in your .profile.
969 printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
971 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
972 supported on your systems. Some systems have a C<locale> command which
973 displays this (also, C<perl -e0> can be used to check locale settings, as
974 it will complain loudly if it cannot set the locale). If it displays something
977 locale: Cannot set LC_CTYPE to default locale: ...
979 Then the locale you specified is not supported on your system.
981 If nothing works and you are sure that everything is set correctly then
982 you will need to remember a little known fact: Some programs just don't
985 =head3 How does rxvt-unicode determine the encoding to use?
989 =head3 Is there an option to switch encodings?
991 Unlike some other terminals, rxvt-unicode has no encoding switch, and no
992 specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
993 UTF-8 or any other encodings with respect to terminal I/O.
995 The reasons is that there exists a perfectly fine mechanism for selecting
996 the encoding, doing I/O and (most important) communicating this to all
997 applications so everybody agrees on character properties such as width
998 and code number. This mechanism is the I<locale>. Applications not using
999 that info will have problems (for example, C<xterm> gets the width of
1000 characters wrong as it uses its own, locale-independent table under all
1003 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1004 programs doing the same (that is, most) will automatically agree in the
1005 interpretation of characters.
1007 Unfortunately, there is no system-independent way to select locales, nor
1008 is there a standard on how locale specifiers will look like.
1010 On most systems, the content of the C<LC_CTYPE> environment variable
1011 contains an arbitrary string which corresponds to an already-installed
1012 locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1013 C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1014 (i.e. C<de> or C<german>) are also common.
1016 Rxvt-unicode ignores all other locale categories, and except for
1017 the encoding, ignores country or language-specific settings,
1018 i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1021 If you want to use a specific encoding you have to make sure you start
1022 rxvt-unicode with the correct C<LC_CTYPE> category.
1024 =head3 Can I switch locales at runtime?
1026 Yes, using an escape sequence. Try something like this, which sets
1027 rxvt-unicode's idea of C<LC_CTYPE>.
1029 printf '\33]701;%s\007' ja_JP.SJIS
1031 See also the previous answer.
1033 Sometimes this capability is rather handy when you want to work in
1034 one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1035 (e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1036 first switches to a locale supported by xjdic and back later:
1038 printf '\33]701;%s\007' ja_JP.SJIS
1040 printf '\33]701;%s\007' de_DE.UTF-8
1042 You can also use xterm's C<luit> program, which usually works fine, except
1043 for some locales where character width differs between program- and
1044 rxvt-unicode-locales.
1046 =head3 I have problems getting my input method working.
1048 Try a search engine, as this is slightly different for every input method server.
1050 Here is a checklist:
1054 =item - Make sure your locale I<and> the imLocale are supported on your OS.
1056 Try C<locale -a> or check the documentation for your OS.
1058 =item - Make sure your locale or imLocale matches a locale supported by your XIM.
1060 For example, B<kinput2> does not support UTF-8 locales, you should use
1061 C<ja_JP.EUC-JP> or equivalent.
1063 =item - Make sure your XIM server is actually running.
1065 =item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1067 When you want to use e.g. B<kinput2>, it must be set to
1068 C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1069 method servers are running with this command:
1071 xprop -root XIM_SERVERS
1077 =head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1079 You can specify separate locales for the input method and the rest of the
1080 terminal, using the resource C<imlocale>:
1082 URxvt.imlocale: ja_JP.EUC-JP
1084 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1085 use your input method. Please note, however, that, depending on your Xlib
1086 version, you may not be able to input characters outside C<EUC-JP> in a
1087 normal way then, as your input method limits you.
1089 =head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1091 Unfortunately, this is unavoidable, as the XIM protocol is racy by
1092 design. Applications can avoid some crashes at the expense of memory
1093 leaks, and Input Methods can avoid some crashes by careful ordering at
1094 exit time. B<kinput2> (and derived input methods) generally succeeds,
1095 while B<SCIM> (or similar input methods) fails. In the end, however,
1096 crashes cannot be completely avoided even if both sides cooperate.
1098 So the only workaround is not to kill your Input Method Servers.
1101 =head2 Operating Systems / Package Maintaining
1103 =head3 I am using Debian GNU/Linux and have a problem...
1105 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
1106 patches that considerably change the behaviour of rxvt-unicode (but
1107 unfortunately this notice has been removed). Before reporting a bug to
1108 the original rxvt-unicode author please download and install the genuine
1109 version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
1110 the problem. If you cannot, chances are that the problems are specific to
1111 Debian GNU/Linux, in which case it should be reported via the Debian Bug
1112 Tracking System (use C<reportbug> to report the bug).
1114 For other problems that also affect the Debian package, you can and
1115 probably should use the Debian BTS, too, because, after all, it's also a
1116 bug in the Debian version and it serves as a reminder for other users that
1117 might encounter the same issue.
1119 =head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1121 You should build one binary with the default options. F<configure>
1122 now enables most useful options, and the trend goes to making them
1123 runtime-switchable, too, so there is usually no drawback to enabling them,
1124 except higher disk and possibly memory usage. The perl interpreter should
1125 be enabled, as important functionality (menus, selection, likely more in
1126 the future) depends on it.
1128 You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
1129 system-wide (except maybe with C<defaults>). This will result in useful
1130 behaviour. If your distribution aims at low memory, add an empty
1131 C<perl-ext-common> resource to the app-defaults file. This will keep the
1132 perl interpreter disabled until the user enables it.
1134 If you can/want build more binaries, I recommend building a minimal
1135 one with C<--disable-everything> (very useful) and a maximal one with
1136 C<--enable-everything> (less useful, it will be very big due to a lot of
1137 encodings built-in that increase download times and are rarely used).
1139 =head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1141 It should be, starting with release 7.1. You are encouraged to properly
1142 install urxvt with privileges necessary for your OS now.
1144 When rxvt-unicode detects that it runs setuid or setgid, it will fork
1145 into a helper process for privileged operations (pty handling on some
1146 systems, utmp/wtmp/lastlog handling on others) and drop privileges
1147 immediately. This is much safer than most other terminals that keep
1148 privileges while running (but is more relevant to urxvt, as it contains
1149 things as perl interpreters, which might be "helpful" to attackers).
1151 This forking is done as the very first within main(), which is very early
1152 and reduces possible bugs to initialisation code run before main(), or
1153 things like the dynamic loader of your system, which should result in very
1156 =head3 On Solaris 9, many line-drawing characters are too wide.
1158 Seems to be a known bug, read
1159 L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
1160 following ugly workaround to get non-double-wide-characters working:
1162 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
1164 =head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1166 Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1167 in your compile environment, or an implementation that implements it,
1168 whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1169 B<wchar_t> is represented as unicode.
1171 As you might have guessed, FreeBSD does neither define this symbol nor
1172 does it support it. Instead, it uses its own internal representation of
1173 B<wchar_t>. This is, of course, completely fine with respect to standards.
1175 However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1176 C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
1178 C<__STDC_ISO_10646__> is the only sane way to support multi-language
1179 apps in an OS, as using a locale-dependent (and non-standardized)
1180 representation of B<wchar_t> makes it impossible to convert between
1181 B<wchar_t> (as used by X11 and your applications) and any other encoding
1182 without implementing OS-specific-wrappers for each and every locale. There
1183 simply are no APIs to convert B<wchar_t> into anything except the current
1186 Some applications (such as the formidable B<mlterm>) work around this
1187 by carrying their own replacement functions for character set handling
1188 with them, and either implementing OS-dependent hacks or doing multiple
1189 conversions (which is slow and unreliable in case the OS implements
1190 encodings slightly different than the terminal emulator).
1192 The rxvt-unicode author insists that the right way to fix this is in the
1193 system libraries once and for all, instead of forcing every app to carry
1194 complete replacements for them :)
1196 =head3 I use Solaris 9 and it doesn't compile/work/etc.
1198 Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
1199 problems with C<wcwidth> and a compile problem.
1201 =head3 How can I use rxvt-unicode under cygwin?
1203 rxvt-unicode should compile and run out of the box on cygwin, using
1204 the X11 libraries that come with cygwin. libW11 emulation is no
1205 longer supported (and makes no sense, either, as it only supported a
1206 single font). I recommend starting the X-server in C<-multiwindow> or
1207 C<-rootless> mode instead, which will result in similar look&feel as the
1208 old libW11 emulation.
1210 At the time of this writing, cygwin didn't seem to support any multi-byte
1211 encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited

2202 =head1 CONFIGURE OPTIONS
2204 General hint: if you get compile errors, then likely your configuration
2205 hasn't been tested well. Either try with C<--enable-everything> or use
2206 the default configuration (i.e. C<--enable-xxx> or C<--disable-xxx>). Of
2207 course, you should always report when a combination doesn't work, so it
2208 can be fixed. Marc Lehmann <rxvt@schmorp.de>.
2214 =item --enable-everything
2216 Add (or remove) support for all non-multichoice options listed in "./configure
2219 You can specify this and then disable options you do not like by
2220 I<following> this with the appropriate C<--disable-...> arguments,
2221 or you can start with a minimal configuration by specifying
2222 C<--disable-everything> and than adding just the C<--enable-...> arguments
2225 =item --enable-xft (default: enabled)
2227 Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
2228 slower and require lots of memory, but as long as you don't use them, you
2231 =item --enable-font-styles (default: on)
2233 Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
2234 styles. The fonts can be set manually or automatically.
2236 =item --with-codesets=NAME,... (default: all)
2238 Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
2239 are always compiled in, which includes most 8-bit character sets). These
2240 codeset tables are used for driving X11 core fonts, they are not required
2241 for Xft fonts, although having them compiled in lets rxvt-unicode choose
2242 replacement fonts more intelligently. Compiling them in will make your
2243 binary bigger (all of together cost about 700kB), but it doesn't increase
2244 memory usage unless you use a font requiring one of these encodings.
2248 all all available codeset groups
2249 zh common chinese encodings
2250 zh_ext rarely used but very big chinese encodings
2251 jp common japanese encodings
2252 jp_ext rarely used but big japanese encodings
2257 =item --enable-xim (default: on)
2259 Add support for XIM (X Input Method) protocol. This allows using
2260 alternative input methods (e.g. kinput2) and will also correctly
2261 set up the input for people using dead keys or compose keys.
2263 =item --enable-unicode3 (default: off)
2265 Recommended to stay off unless you really need non-BMP characters.
2267 Enable direct support for displaying unicode codepoints above
2268 65535 (the basic multilingual page). This increases storage
2269 requirements per character from 2 to 4 bytes. X11 fonts do not yet
2270 support these extra characters, but Xft does.
2272 Please note that rxvt-unicode can store unicode code points >65535
2273 even without this flag, but the number of such characters is
2274 limited to a few thousand (shared with combining characters,
2275 see next switch), and right now rxvt-unicode cannot display them
2276 (input/output and cut&paste still work, though).
2278 =item --enable-combining (default: on)
2280 Enable automatic composition of combining characters into
2281 composite characters. This is required for proper viewing of text
2282 where accents are encoded as seperate unicode characters. This is
2283 done by using precomposited characters when available or creating
2284 new pseudo-characters when no precomposed form exists.
2286 Without --enable-unicode3, the number of additional precomposed
2287 characters is somewhat limited (the 6400 private use characters will be
2288 (ab-)used). With --enable-unicode3, no practical limit exists.
2290 This option will also enable storage (but not display) of characters
2291 beyond plane 0 (>65535) when --enable-unicode3 was not specified.
2293 The combining table also contains entries for arabic presentation forms,
2294 but these are not currently used. Bug me if you want these to be used (and
2295 tell me how these are to be used...).
2297 =item --enable-fallback(=CLASS) (default: Rxvt)
2299 When reading resource settings, also read settings for class CLASS. To
2300 disable resource fallback use --disable-fallback.
2302 =item --with-res-name=NAME (default: urxvt)
2304 Use the given name as default application name when
2305 reading resources. Specify --with-res-name=rxvt to replace rxvt.
2307 =item --with-res-class=CLASS /default: URxvt)
2309 Use the given class as default application class
2310 when reading resources. Specify --with-res-class=Rxvt to replace
2313 =item --enable-utmp (default: on)
2315 Write user and tty to utmp file (used by programs like F<w>) at
2316 start of rxvt execution and delete information when rxvt exits.
2318 =item --enable-wtmp (default: on)
2320 Write user and tty to wtmp file (used by programs like F<last>) at
2321 start of rxvt execution and write logout when rxvt exits. This
2322 option requires --enable-utmp to also be specified.
2324 =item --enable-lastlog (default: on)
2326 Write user and tty to lastlog file (used by programs like
2327 F<lastlogin>) at start of rxvt execution. This option requires
2328 --enable-utmp to also be specified.
2330 =item --enable-xpm-background (default: on)
2332 Add support for XPM background pixmaps.
2334 =item --enable-transparency (default: on)
2336 Add support for inheriting parent backgrounds thus giving a fake
2337 transparency to the term.
2339 =item --enable-fading (default: on)
2341 Add support for fading the text when focus is lost (requires C<--enable-transparency>).
2343 =item --enable-tinting (default: on)
2345 Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
2347 =item --enable-rxvt-scroll (default: on)
2349 Add support for the original rxvt scrollbar.
2351 =item --enable-next-scroll (default: on)
2353 Add support for a NeXT-like scrollbar.
2355 =item --enable-xterm-scroll (default: on)
2357 Add support for an Xterm-like scrollbar.
2359 =item --enable-plain-scroll (default: on)
2361 Add support for a very unobtrusive, plain-looking scrollbar that
2362 is the favourite of the rxvt-unicode author, having used it for
2365 =item --enable-ttygid (default: off)
2367 Change tty device setting to group "tty" - only use this if
2368 your system uses this type of security.
2370 =item --disable-backspace-key
2372 Removes any handling of the backspace key by us - let the X server do it.
2374 =item --disable-delete-key
2376 Removes any handling of the delete key by us - let the X server
2379 =item --disable-resources
2381 Removes any support for resource checking.
2383 =item --disable-swapscreen
2385 Remove support for secondary/swap screen.
2387 =item --enable-frills (default: on)
2389 Add support for many small features that are not essential but nice to
2390 have. Normally you want this, but for very small binaries you may want to
2393 A non-exhaustive list of features enabled by C<--enable-frills> (possibly
2394 in combination with other switches) is:
2397 EWMH-hints (pid, utf8 names) and protocols (ping)
2399 seperate underline colour (-underlineColor)
2400 settable border widths and borderless switch (-w, -b, -bl)
2401 visual depth selection (-depth)
2402 settable extra linespacing /-lsp)
2403 iso-14755 5.1 (basic) support
2404 tripleclickwords (-tcw)
2405 settable insecure mode (-insecure)
2406 keysym remapping support
2407 cursor blinking and underline cursor (-cb, -uc)
2408 XEmbed support (-embed)
2410 hold on exit (-hold)
2411 skip builtin block graphics (-sbg)
2412 separate highlightcolor support (-hc)
2414 It also enables some non-essential features otherwise disabled, such as:
2416 some round-trip time optimisations
2417 nearest color allocation on pseudocolor screens
2418 UTF8_STRING support for selection
2419 sgr modes 90..97 and 100..107
2420 backindex and forwardindex escape sequences
2421 view change/zero scrollback escape sequences
2422 locale switching escape sequence
2423 window op and some xterm/OSC escape sequences
2424 rectangular selections
2425 trailing space removal for selections
2426 verbose X error handling
2428 =item --enable-iso14755 (default: on)
2430 Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
2431 F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
2432 C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
2435 =item --enable-keepscrolling (default: on)
2437 Add support for continual scrolling of the display when you hold
2438 the mouse button down on a scrollbar arrow.
2440 =item --enable-selectionscrolling (default: on)
2442 Add support for scrolling when the selection moves to the top or
2443 bottom of the screen.
2445 =item --enable-mousewheel (default: on)
2447 Add support for scrolling via mouse wheel or buttons 4 & 5.
2449 =item --enable-slipwheeling (default: on)
2451 Add support for continual scrolling (using the mouse wheel as an
2452 accelerator) while the control key is held down. This option
2453 requires --enable-mousewheel to also be specified.
2455 =item --enable-smart-resize (default: off)
2457 Add smart growth/shrink behaviour when resizing.
2458 This should keep the window corner which is closest to a corner of
2459 the screen in a fixed position.
2461 =item --enable-pointer-blank (default: on)
2463 Add support to have the pointer disappear when typing or inactive.
2465 =item --enable-perl (default: on)
2467 Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
2468 manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the
2469 files in F<src/perl-ext/> for the extensions that are installed by
2470 default. The perl interpreter that is used can be specified via the
2471 C<PERL> environment variable when running configure. Even when compiled
2472 in, perl will I<not> be initialised when all extensions have been disabled
2473 C<-pe "" --perl-ext-common "">, so it should be safe to enable from a
2474 resource standpoint.
2476 =item --with-name=NAME (default: urxvt)
2478 Set the basename for the installed binaries, resulting
2479 in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
2482 =item --with-term=NAME (default: rxvt-unicode)
2484 Change the environmental variable for the terminal to NAME.
2486 =item --with-terminfo=PATH
2488 Change the environmental variable for the path to the terminfo tree to
2493 Use the X Window System (pretty much default, eh?).
2495 =item --with-xpm-includes=DIR
2497 Look for the XPM includes in DIR.
2499 =item --with-xpm-library=DIR
2501 Look for the XPM library in DIR.
2505 Not needed - define via --enable-xpm-background.
2511 Marc Lehmann <rxvt@schmorp.de> converted this document to pod and
2512 reworked it from the original Rxvt documentation, which was done by Geoff
2513 Wing <gcw@pobox.com>, who in turn used the XTerm documentation and other
