   Meta, Features & Commandline	Issues
       My question isn't answered here,	can I ask a human?

       Before sending me mail, you could go to IRC: "",
       channel "#rxvt-unicode" has some	rxvt-unicode enthusiasts that might be
       interested in learning about new	and exciting problems (but not FAQs

       I use Gentoo, and I have	a problem...

       There are two big problems with Gentoo Linux: first, most if not	all
       Gentoo systems are completely broken (missing or	mismatched header
       files, broken compiler etc. are just the	tip of the iceberg); secondly,
       it should be called Gentoo GNU/Linux.

       For these reasons, it is	impossible to support rxvt-unicode on Gentoo.
       Problems	appearing on Gentoo systems will usually simply	be ignored
       unless they can be reproduced on	non-Gentoo systems.

       Does it support tabs, can I have	a tabbed rxvt-unicode?

       Beginning with version 7.3, there is a perl extension that implements a
       simple tabbed terminal. It is installed by default, so any of these
       should give you tabs:

	  urxvt	-pe tabbed

	  URxvt.perl-ext-common: default,tabbed

       It will also work fine with tabbing functionality of many window
       managers	or similar tabbing programs, and its embedding-features	allow
       it to be	embedded into other programs, as witnessed by doc/rxvt-tabbed
       or the upcoming "Gtk2::URxvt" perl module, which	features a tabbed
       urxvt (murxvt) terminal as an example embedding application.

       How do I	know which rxvt-unicode	version	I'm using?

       The version number is displayed with the	usage (-h). Also the escape
       sequence	"ESC [ 8 n" sets the window title to the version number. When
       using the urxvtc	client,	the version displayed is that of the daemon.

       Rxvt-unicode uses gobs of memory, how can I reduce that?

       Rxvt-unicode tries to obey the rule of not charging you for something
       you don't use. One thing	you should try is to configure out all
       settings	that you don't need, for example, Xft support is a resource
       hog by design, when used. Compiling it out ensures that no Xft font
       will be loaded accidentally when	rxvt-unicode tries to find a font for
       your characters.

       Also, many people (me included) like large windows and even larger
       scrollback buffers: Without "--enable-unicode3",	rxvt-unicode will use
       6 bytes per screen cell.	For a 160x?? window this amounts to almost a
       kilobyte	per line. A scrollback buffer of 10000 lines will then (if
       full) use 10 Megabytes of memory. With "--enable-unicode3" it gets
       worse, as rxvt-unicode then uses	8 bytes	per screen cell.

       How can I start urxvtd in a race-free way?

       Try "urxvtd -f -o", which tells urxvtd to open the display, create the
       listening socket	and then fork.

       How can I start urxvtd automatically when I run urxvtc?

       If you want to start urxvtd automatically whenever you run urxvtc and
       the daemon isn't	running	yet, use this script:

	  urxvtc "$@"
	  if [ $? -eq 2	]; then
	     urxvtd -q -o -f
	     urxvtc "$@"

       This tries to create a new terminal, and	if fails with exit status 2,
       meaning it couldn't connect to the daemon, it will start	the daemon and
       re-run the command. Subsequent invocations of the script	will re-use
       the existing daemon.

       How do I	distinguish whether I'm	running	rxvt-unicode or	a regular
       xterm? I	need this to decide about setting colours etc.

       The original rxvt and rxvt-unicode always export	the variable
       "COLORTERM", so you can check and see if	that is	set. Note that several
       programs, JED, slrn, Midnight Commander automatically check this
       variable	to decide whether or not to use	colour.

       How do I	set the	correct, full IP address for the DISPLAY variable?

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

       Courtesy	of Chuck Blake <cblake@BBN.COM>	with the following shell
       script snippets:

	  # Bourne/Korn/POSIX family of	shells:
	  [ ${TERM:-foo} = foo ] && TERM=xterm # assume	an xterm if we don't know
	  if [ ${TERM:-foo} = xterm ]; then
	     stty -icanon -echo	min 0 time 15 #	see if enhanced	rxvt or	not
	     printf "\eZ"
	     read term_id
	     stty icanon echo
	     if	[ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ];	then
		printf '\e[7n'	      #	query the rxvt we are in for the DISPLAY string
		read DISPLAY	      #	set it in our local shell

       How do I	compile	the manual pages on my own?

       You need	to have	a recent version of perl installed as /usr/bin/perl,
       one that	comes with pod2man, pod2text and pod2xhtml (from Pod::Xhtml).
       Then go to the doc subdirectory and enter "make alldoc".

       Isn't rxvt-unicode supposed to be small?	Don't all those	features

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

	   text	   data	    bss	    drs	    rss	filename
	  98398	   1664	     24	  15695	   1824	rxvt --disable-everything
	 188985	   9048	  66616	  18222	   1788	urxvt --disable-everything

       When you	"--enable-everything" (which is	unfair,	as this	involves xft
       and full	locale/XIM support which are quite bloaty inside libX11	and my
       libc), the two diverge, but not unreasonably so.

	   text	   data	    bss	    drs	    rss	filename
	 163431	   2152	     24	  20123	   2060	rxvt --enable-everything
	1035683	  49680	  66648	  29096	   3680	urxvt --enable-everything

       The very	large size of the text section is explained by the east-asian
       encoding	tables,	which, if unused, take up disk space but nothing else
       and can be compiled out unless you rely on X11 core fonts that use
       those encodings.	The BSS	size comes from	the 64k	emergency buffer that
       my c++ compiler allocates (but of course	doesn't	use unless you are out
       of memory). Also, using an xft font instead of a	core font immediately
       adds a few megabytes of RSS. Xft	indeed is responsible for a lot	of RSS
       even when not used.

       Of course, due to every character using two or four bytes instead of
       one, a large scrollback buffer will ultimately make rxvt-unicode	use
       more memory.

       Compared	to e.g.	Eterm (5112k), aterm (3132k) and xterm (4680k),	this
       still fares rather well.	And compared to	some monsters like gnome-
       terminal	(21152k	+ extra	4204k in separate processes) or	konsole
       (22200k + extra 43180k in daemons that stay around after	exit, plus
       half a minute of	startup	time, including	the hundreds of	warnings it
       spits out), it fares extremely well *g*.

       Why C++,	isn't that unportable/bloated/uncool?

       Is this a question? :) It comes up very often. The simple answer	is: I
       had to write it,	and C++	allowed	me to write and	maintain it in a
       fraction	of the time and	effort (which is a scarce resource for me).
       Put even	shorter: It simply wouldn't exist without C++.

       My personal stance on this is that C++ is less portable than C, but in
       the case	of rxvt-unicode	this hardly matters, as	its portability	limits
       are defined by things like X11, pseudo terminals, locale	support	and
       unix domain sockets, which are all less portable	than C++ itself.

       Regarding the bloat, see	the above question: It's easy to write
       programs	in C that use gobs of memory, and certainly possible to	write
       programs	in C++ that don't. C++ also often comes	with large libraries,
       but this	is not necessarily the case with GCC. Here is what rxvt	links
       against on my system with a minimal config: => /usr/X11R6/lib/ (0x00002aaaaabc3000) => /lib/ (0x00002aaaaadde000) =>	/lib/	(0x00002aaaab01d000)
	  /lib64/ (0x00002aaaaaaab000)

       And here	is rxvt-unicode: => /usr/X11R6/lib/ (0x00002aaaaabc3000)	=> /lib/ (0x00002aaaaada2000) => /lib/ (0x00002aaaaaeb0000) =>	/lib/	(0x00002aaaab0ee000)
	  /lib64/ (0x00002aaaaaaab000)

       No large	bloated	libraries (of course, none were	linked in statically),
       except maybe libX11 :)

   Rendering, Font & Look and Feel Issues
       I can't get transparency	working, what am I doing wrong?

       First of	all, transparency isn't	officially supported in	rxvt-unicode,
       so you are mostly on your own. Do not bug the author about it (but you
       may bug everybody else).	Also, if you can't get it working consider it
       a rite of passage: ... and you failed.

       Here are	four ways to get transparency. Do read the manpage and option
       descriptions for	the programs mentioned and rxvt-unicode. Really, do

       1. Use transparent mode:

	  Esetroot wallpaper.jpg
	  urxvt	-tr -tint red -sh 40

       That works. If you think	it doesn't, you	lack transparency and tinting
       support,	or you are unable to read.  This method	requires that the
       background-setting program sets the _XROOTPMAP_ID or ESETROOT_PMAP_ID
       property. Compatible programs are Esetroot, hsetroot and	feh.

       2. Use a	simple pixmap and emulate pseudo-transparency. This enables
       you to use effects other	than tinting and shading: Just
       shade/tint/whatever your	picture	with gimp or any other tool:

	  convert wallpaper.jpg	-blur 20x20 -modulate 30 background.jpg
	  urxvt	-pixmap	"background.jpg;:root"

       That works. If you think	it doesn't, you	lack GDK-PixBuf	support, or
       you are unable to read.

       3. Use an ARGB visual:

	  urxvt	-depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc

       This requires XFT support, and the support of your X-server. If that
       doesn't work for	you, blame Xorg	and Keith Packard. ARGB	visuals	aren't
       there yet, no matter what they claim. Rxvt-Unicode contains the
       necessary bugfixes and workarounds for Xft and Xlib to make it work,
       but that	doesn't	mean that your WM has the required kludges in place.

       4. Use xcompmgr and let it do the job:

	 xprop -frame -f _NET_WM_WINDOW_OPACITY	32c \
	       -set _NET_WM_WINDOW_OPACITY 0xc0000000

       Then click on a window you want to make transparent. Replace 0xc0000000
       by other	values to change the degree of opacity.	If it doesn't work and
       your server crashes, you	got to keep the	pieces.

       Why does	rxvt-unicode sometimes leave pixel droppings?

       Most fonts were not designed for	terminal use, which means that
       character size varies a lot. A font that	is otherwise fine for terminal
       use might contain some characters that are simply too wide. Rxvt-
       unicode will avoid these	characters. For	characters that	are just "a
       bit" too	wide a special "careful" rendering mode	is used	that redraws
       adjacent	characters.

       All of this requires that fonts do not lie about	character sizes,
       however:	Xft fonts often	draw glyphs larger than	their acclaimed
       bounding	box, and rxvt-unicode has no way of detecting this (the
       correct way is to ask for the character bounding	box, which
       unfortunately is	wrong in these cases).

       It's not	clear (to me at	least),	whether	this is	a bug in Xft,
       freetype, or the	respective font. If you	encounter this problem you
       might try using the "-lsp" option to give the font more height. If that
       doesn't work, you might be forced to use	a different font.

       All of this is not a problem when using X11 core	fonts, as their
       bounding	box data is correct.

       How can I keep rxvt-unicode from	using reverse video so much?

       First of	all, make sure you are running with the	right terminal
       settings	("TERM=rxvt-unicode"), which will get rid of most of these
       effects.	Then make sure you have	specified colours for italic and bold,
       as otherwise rxvt-unicode might use reverse video to simulate the

	  URxvt.colorBD:  white
	  URxvt.colorIT:  green

       Some programs assume totally weird colours (red instead of blue), how
       can I fix that?

       For some	unexplainable reason, some rare	programs assume	a very weird
       colour palette when confronted with a terminal with more	than the
       standard	8 colours (rxvt-unicode	supports 88). The right	fix is,	of
       course, to fix these programs not to assume non-ISO colours without
       very good reasons.

       In the meantime,	you can	either edit your "rxvt-unicode"	terminfo
       definition to only claim	8 colour support or use	"TERM=rxvt", which
       will fix	colours	but keep you from using	other rxvt-unicode features.

       Can I switch the	fonts at runtime?

       Yes, using an escape sequence. Try something like this, which has the
       same effect as using the	"-fn" switch, and takes	effect immediately:

	  printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"

       This is useful if you e.g. work primarily with japanese (and prefer a
       japanese	font), but you have to switch to chinese temporarily, where
       japanese	fonts would only be in your way.

       You can think of	this as	a kind of manual ISO-2022 switching.

       Why do italic characters	look as	if clipped?

       Many fonts have difficulties with italic	characters and hinting.	For
       example,	the otherwise very nicely hinted font "xft:Bitstream Vera Sans
       Mono" completely	fails in its italic face. A workaround might be	to
       enable freetype autohinting, i.e. like this:

	  URxvt.italicFont:	   xft:Bitstream Vera Sans Mono:italic:autohint=true
	  URxvt.boldItalicFont:	   xft:Bitstream Vera Sans Mono:bold:italic:autohint=true

       Can I speed up Xft rendering somehow?

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

       Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?

       Rxvt-unicode will use whatever you specify as a font. If	it needs to
       fall back to its	default	font search list it will prefer	X11 core
       fonts, because they are small and fast, and then	use Xft	fonts. It has
       antialiasing disabled for most of them, because the author thinks they
       look best that way.

       If you want antialiasing, you have to specify the fonts manually.

       What's with this	bold/blink stuff?

       If no bold colour is set	via "colorBD:",	bold will invert text using
       the standard foreground colour.

       For the standard	background colour, blinking will actually make the
       text blink when compiled	with "--enable-text-blink". Without
       "--enable-text-blink", the blink	attribute will be ignored.

       On ANSI colours,	bold/blink attributes are used to set high-intensity
       foreground/background colours.

       color0-7	are the	low-intensity colours.

       color8-15 are the corresponding high-intensity colours.

       I don't like the	screen colours.	 How do	I change them?

       You can change the screen colours at run-time using ~/.Xdefaults
       resources (or as	long-options).

       Here are	values that are	supposed to resemble a VGA screen, including
       the murky brown that passes for low-intensity yellow:

	  URxvt.color0:	  #000000
	  URxvt.color1:	  #A80000
	  URxvt.color2:	  #00A800
	  URxvt.color3:	  #A8A800
	  URxvt.color4:	  #0000A8
	  URxvt.color5:	  #A800A8
	  URxvt.color6:	  #00A8A8
	  URxvt.color7:	  #A8A8A8

	  URxvt.color8:	  #000054
	  URxvt.color9:	  #FF0054
	  URxvt.color10:  #00FF54
	  URxvt.color11:  #FFFF54
	  URxvt.color12:  #0000FF
	  URxvt.color13:  #FF00FF
	  URxvt.color14:  #00FFFF
	  URxvt.color15:  #FFFFFF

       And here	is a more complete set of non-standard colours.

	  URxvt.cursorColor:  #dc74d1
	  URxvt.pointerColor: #dc74d1
	  URxvt.background:   #0e0e0e
	  URxvt.foreground:   #4ad5e1
	  URxvt.color0:	      #000000
	  URxvt.color8:	      #8b8f93
	  URxvt.color1:	      #dc74d1
	  URxvt.color9:	      #dc74d1
	  URxvt.color2:	      #0eb8c7
	  URxvt.color10:      #0eb8c7
	  URxvt.color3:	      #dfe37e
	  URxvt.color11:      #dfe37e
	  URxvt.color5:	      #9e88f0
	  URxvt.color13:      #9e88f0
	  URxvt.color6:	      #73f7ff
	  URxvt.color14:      #73f7ff
	  URxvt.color7:	      #e1dddd
	  URxvt.color15:      #e1dddd

       They have been described	(not by	me) as "pretty girly".

       Why do some characters look so much different than others?

       See next	entry.

       How does	rxvt-unicode choose fonts?

       Most fonts do not contain the full range	of Unicode, which is fine.
       Chances are that	the font you (or the admin/package maintainer of your
       system/os) have specified does not cover	all the	characters you want to

       rxvt-unicode makes a best-effort	try at finding a replacement font.
       Often the result	is fine, but sometimes the chosen font looks
       bad/ugly/wrong. Some fonts have totally strange characters that don't
       resemble	the correct glyph at all, and rxvt-unicode lacks the
       artificial intelligence to detect that a	specific glyph is wrong: it
       has to believe the font that the	characters it claims to	contain	indeed
       look correct.

       In that case, select a font of your taste and add it to the font	list,

	  urxvt	-fn basefont,font2,font3...

       When rxvt-unicode sees a	character, it will first look at the base
       font. If	the base font does not contain the character, it will go to
       the next	font, and so on. Specifying your own fonts will	also speed up
       this search and use less	resources within rxvt-unicode and the

       The only	limitation is that none	of the fonts may be larger than	the
       base font, as the base font defines the terminal	character cell size,
       which must be the same due to the way terminals work.

       Why do some chinese characters look so different	than others?

       This is because there is	a difference between script and	language --
       rxvt-unicode does not know which	language the text that is output is,
       as it only knows	the unicode character codes. If	rxvt-unicode first
       sees a japanese/chinese character, it might choose a japanese font for
       display.	Subsequent japanese characters will use	that font. Now,	many
       chinese characters aren't represented in	japanese fonts,	so when	the
       first non-japanese character comes up, rxvt-unicode will	look for a
       chinese font -- unfortunately at	this point, it will still use the
       japanese	font for chinese characters that are also in the japanese

       The workaround is easy: just tag	a chinese font at the end of your font
       list (see the previous question). The key is to view the	font list as a
       preference list:	If you expect more japanese, list a japanese font
       first. If you expect more chinese, put a	chinese	font first.

       In the future it	might be possible to switch language preferences at
       runtime (the internal data structure has	no problem with	using
       different fonts for the same character at the same time,	but no
       interface for this has been designed yet).

       Until then, you might get away with switching fonts at runtime (see
       "Can I switch the fonts at runtime?" later in this document).

       How can I make mplayer display video correctly?

       We are working on it, in	the meantime, as a workaround, use something

	  urxvt	-b 600 -geometry 20x1 -e sh -c 'mplayer	-wid $WINDOWID file...'

       Why is the cursor now blinking in emacs/vi/...?

       This is likely caused by	your editor/program's use of the "cvvis"
       terminfo	capability. Emacs uses it by default, as well as some versions
       of vi and possibly other	programs.

       In emacs, you can switch	that off by adding this	to your	".emacs" file:

	  (setq	visible-cursor nil)

       For other programs, if they do not have an option, your have to remove
       the "cvvis" capability from the terminfo	description.

       When urxvt first	added the blinking cursor option, it didn't add	a
       "cvvis" capability, which served	no purpose before. Version 9.21
       introduced "cvvis" (and the ability to control blinking independent of
       cursor shape) for compatibility with other terminals, which
       traditionally use a blinking cursor for "cvvis".	This also reflects the
       intent of programs such as emacs, who expect "cvvis" to enable a
       blinking	cursor.

   Keyboard, Mouse & User Interaction
       The new selection selects pieces	that are too big, how can I select
       single words?

       If you want to select e.g. alphanumeric words, you can use the
       following setting:

	  URxvt.selection.pattern-0: ([[:word:]]+)

       If you click more than twice, the selection will	be extended more and

       To get a	selection that is very similar to the old code,	try this

	  URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)

       Please also note	that the LeftClick Shift-LeftClick combination also
       selects words like the old code.

       I don't like the	new selection/popups/hotkeys/perl, how do I
       change/disable it?

       You can disable the perl	extension completely by	setting	the perl-ext-
       common resource to the empty string, which also keeps rxvt-unicode from
       initialising perl, saving memory.

       If you only want	to disable specific features, you first	have to
       identify	which perl extension is	responsible. For this, read the
       section PREPACKAGED EXTENSIONS in the urxvtperl(3) manpage. For
       example,	to disable the selection-popup and option-popup, specify this
       perl-ext-common resource:

	  URxvt.perl-ext-common: default,-selection-popup,-option-popup

       This will keep the default extensions, but disable the two popup
       extensions. Some	extensions can also be configured, for example,
       scrollback search mode is triggered by M-s. You can move	it to any
       other combination by adding a keysym resource that binds	the desired
       combination to the "start" action of "searchable-scrollback" and
       another one that	binds M-s to the "builtin:" action:

	  URxvt.keysym.CM-s: searchable-scrollback:start
	  URxvt.keysym.M-s: builtin:

       The cursor moves	when selecting text in the current input line, how do
       I switch	this off?

       See next	entry.

       During rlogin/ssh/telnet/etc. sessions, clicking	near the cursor
       outputs strange escape sequences, how do	I fix this?

       These are caused	by the "readline" perl extension. Under	normal
       circumstances, it will move your	cursor around when you click into the
       line that contains it. It tries hard not	to do this at the wrong
       moment, but when	running	a program that doesn't parse cursor movements
       or in some cases	during rlogin sessions,	it fails to detect this

       You can permanently switch this feature off by disabling	the "readline"

	  URxvt.perl-ext-common: default,-readline

       My numeric keypad acts weird and	generates differing output?

       Some Debian GNU/Linux users seem	to have	this problem, although no
       specific	details	were reported so far. It is possible that this is
       caused by the wrong "TERM" setting, although the	details	of whether and
       how this	can happen are unknown,	as "TERM=rxvt" should offer a
       compatible keymap. See the answer to the	previous question, and please
       report if that helped.

       My Compose (Multi_key) key is no	longer working.

       The most	common causes for this are that	either your locale is not set
       correctly, or you specified a preeditType that is not supported by your
       input method. For example, if you specified OverTheSpot and your	input
       method (e.g. the	default	input method handling Compose keys) does not
       support this (for instance because it is	not visual), then rxvt-unicode
       will continue without an	input method.

       In this case either do not specify a preeditType	or specify more	than
       one pre-edit style, such	as OverTheSpot,Root,None.

       If it still doesn't work, then maybe your input method doesn't support
       compose sequences - to fall back	to the built-in	one, make sure you
       don't specify an	input method via "-im" or "XMODIFIERS".

       I cannot	type "Ctrl-Shift-2" to get an ASCII NUL	character due to ISO

       Either try "Ctrl-2" alone (it often is mapped to	ASCII NUL even on
       international keyboards)	or simply use ISO 14755	support	to your
       advantage, typing <Ctrl-Shift-0>	to get a ASCII NUL. This works for
       other codes, too, such as "Ctrl-Shift-1-d" to type the default telnet
       escape character	and so on.

       Mouse cut/paste suddenly	no longer works.

       Make sure that mouse reporting is actually turned off since killing
       some editors prematurely	may leave it active. I've heard	that tcsh may
       use mouse reporting unless it is	otherwise specified. A quick check is
       to see if cut/paste works when the Alt or Shift keys are	pressed.

       What's with the strange Backspace/Delete	key behaviour?

       Assuming	that the physical Backspace key	corresponds to the Backspace
       keysym (not likely for Linux ...	see the	following question) there are
       two standard values that	can be used for	Backspace: "^H"	and "^?".

       Historically, either value is correct, but rxvt-unicode adopts the
       debian policy of	using "^?" when	unsure,	because	it's the one and only
       correct choice :).

       It is possible to toggle	between	"^H" and "^?" with the DECBKM private

	  # use	Backspace = ^H
	  $ stty erase ^H
	  $ printf "\e[?67h"

	  # use	Backspace = ^?
	  $ stty erase ^?
	  $ printf "\e[?67l"

       This helps satisfy some of the Backspace	discrepancies that occur, but
       if you use Backspace = "^H", make sure that the termcap/terminfo	value
       properly	reflects that.

       The Delete key is a another casualty of the ill-defined Backspace
       problem.	 To avoid confusion between the	Backspace and Delete keys, the
       Delete key has been assigned an escape sequence to match	the vt100 for
       Execute ("ESC [ 3 ~") and is in the supplied termcap/terminfo.

       Some other Backspace problems:

       some editors use	termcap/terminfo, some editors (vim I'm	told) expect
       Backspace = ^H, GNU Emacs (and Emacs-like editors) use ^H for help.

       Perhaps someday this will all be	resolved in a consistent manner.

       I don't like the	key-bindings.  How do I	change them?

       There are some compile-time selections available	via configure. Unless
       you have	run "configure"	with the "--disable-resources" option you can
       use the `keysym'	resource to alter the keystrings associated with

       Here's an example for a URxvt session started using "urxvt -name	URxvt"

	  URxvt.keysym.Prior:	      \033[5~
	  URxvt.keysym.Next:	      \033[6~
	  URxvt.keysym.Home:	      \033[7~
	  URxvt.keysym.End:	      \033[8~
	  URxvt.keysym.Up:	      \033[A
	  URxvt.keysym.Down:	      \033[B
	  URxvt.keysym.Right:	      \033[C
	  URxvt.keysym.Left:	      \033[D

       See some	more examples in the documentation for the keysym resource.

       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

	  KP_Insert == Insert
	  F22 == Print
	  F27 == Home
	  F29 == Prior
	  F33 == End
	  F35 == Next

       Rather than have	rxvt-unicode try to accommodate	all the	various
       possible	keyboard mappings, it is better	to use `xmodmap' to remap the
       keys as required	for your particular machine.

   Terminal Configuration
       Can I see a typical configuration?

       The default configuration tries to be xterm-like, which I don't like
       that much, but it's least surprise to regular users.

       As a rxvt or rxvt-unicode user, you are practically supposed to invest
       time into customising your terminal. To get you started,	here is	the
       author's	.Xdefaults entries, with comments on what they do. It's
       certainly not typical, but what's typical...

	  URxvt.cutchars: "()*,<>[]{}|'
	  URxvt.print-pipe: cat	>/tmp/xxx

       These are just for testing stuff.

	  URxvt.imLocale: ja_JP.UTF-8
	  URxvt.preeditType: OnTheSpot,None

       This tells rxvt-unicode to use a	special	locale when communicating with
       the X Input Method, and also tells it to	only use the OnTheSpot pre-
       edit type, which	requires the "xim-onthespot" perl extension but
       rewards me with correct-looking fonts.

	  URxvt.perl-lib: /root/lib/urxvt
	  URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
	  URxvt.selection.pattern-0: ( at .*? line \\d+)
	  URxvt.selection.pattern-1: ^(/[^:]+):\
	  URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
	  URxvt.selection-autotransform.1: s/^ at (.*?)	line (\\d+)$/:e	\\Q$1\\E\\x0d:$2\\x0d/

       This is my perl configuration. The first	two set	the perl library
       directory and also tells	urxvt to use a large number of extensions. I
       develop for myself mostly, so I actually	use most of the	extensions I

       The selection stuff mainly makes	the selection perl-error-message aware
       and tells it to convert perl error messages into	vi-commands to load
       the relevant file and go	to the error line number.

	  URxvt.scrollstyle:	  plain
	  URxvt.secondaryScroll:  true

       As the documentation says: plain	is the preferred scrollbar for the
       author. The "secondaryScroll" configures	urxvt to scroll	in full-screen
       apps, like screen, so lines scrolled out	of screen end up in urxvt's
       scrollback buffer.

	  URxvt.background:	  #000000
	  URxvt.foreground:	  gray90
	  URxvt.color7:		  gray90
	  URxvt.colorBD:	  #ffffff
	  URxvt.cursorColor:	  #e0e080
	  URxvt.throughColor:	  #8080f0
	  URxvt.highlightColor:	  #f0f0f0

       Some colours. Not sure which ones are being used	or even	non-defaults,
       but these are in	my .Xdefaults. Most notably, they set
       foreground/background to	light gray/black, and also make	sure that the
       colour 7	matches	the default foreground colour.

	  URxvt.underlineColor:	  yellow

       Another colour, makes underline lines look different. Sometimes hurts,
       but is mostly a nice effect.

	  URxvt.geometry:	  154x36
	  URxvt.loginShell:	  false
	  URxvt.meta:		  ignore
	  URxvt.utmpInhibit:	  true

       Uh, well, should	be mostly self-explanatory. By specifying some
       defaults	manually, I can	quickly	switch them for	testing.

	  URxvt.saveLines:	  8192

       A large scrollback buffer is essential. Really.

	  URxvt.mapAlert:	  true

       The only	case I use it is for my	IRC window, which I like to keep
       iconified till people msg me (which beeps).

	  URxvt.visualBell:	  true

       The audible bell	is often annoying, especially when in a	crowd.

	  URxvt.insecure:	  true

       Please don't hack my mutt! Ooops...

	  URxvt.pastableTabs:	  false

       I once thought this is a	great idea.

	  urxvt.font:		  9x15bold,\
				  -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
				  [codeset=JISX0208]xft:Kochi Gothic, \
				  xft:Bitstream	Vera Sans Mono:autohint=true, \
	  urxvt.boldFont:	  -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
	  urxvt.italicFont:	  xft:Bitstream	Vera Sans Mono:italic:autohint=true
	  urxvt.boldItalicFont:	  xft:Bitstream	Vera Sans Mono:bold:italic:autohint=true

       I wrote rxvt-unicode to be able to specify fonts	exactly. So don't be
       overwhelmed. A special note: the	"9x15bold" mentioned above is actually
       the version from	XFree-3.3, as XFree-4 replaced it by a totally
       different font (different glyphs	for ";"	and many other harmless
       characters), while the second font is actually the "9x15bold" from
       XFree4/XOrg. The	bold version has less chars than the medium version,
       so I use	it for rare characters,	too. When editing sources with vim, I
       use italic for comments and other stuff,	which looks quite good with
       Bitstream Vera anti-aliased.

       Terminus	is a quite bad font (many very wrong glyphs), but for most of
       my purposes, it works, and gives	a different look, as my	normal (Non-
       bold) font is already bold, and I want to see a difference between bold
       and normal fonts.

       Please note that	I used the "urxvt" instance name and not the "URxvt"
       class name. That	is because I use different configs for different
       purposes, for example, my IRC window is started with "-name IRC", and
       uses these defaults:

	  IRC*title:		  IRC
	  IRC*geometry:		  87x12+535+542
	  IRC*saveLines:	  0
	  IRC*mapAlert:		  true
	  IRC*font:		  suxuseuro
	  IRC*boldFont:		  suxuseuro
	  IRC*colorBD:		  white
	  IRC*keysym.M-C-1:	  command:\033]710;suxuseuro\007\033]711;suxuseuro\007
	  IRC*keysym.M-C-2:	  command:\033]710;9x15bold\007\033]711;9x15bold\007

       "Alt-Ctrl-1" and	"Alt-Ctrl-2" switch between two	different font sizes.
       "suxuseuro" allows me to	keep an	eye (and actually read)	stuff while
       keeping a very small window. If somebody	pastes something complicated
       (e.g. japanese),	I temporarily switch to	a larger font.

       The above is all	in my ".Xdefaults" (I don't use	".Xresources" nor
       "xrdb").	I also have some resources in a	separate ".Xdefaults-hostname"
       file for	different hosts, for example, on my main desktop, I use:

	  URxvt.keysym.C-M-q: command:\033[3;5;5t
	  URxvt.keysym.C-M-y: command:\033[3;5;606t
	  URxvt.keysym.C-M-e: command:\033[3;1605;5t
	  URxvt.keysym.C-M-c: command:\033[3;1605;606t
	  URxvt.keysym.C-M-p: perl:test

       The first for keysym definitions	allow me to quickly bring some windows
       in the layout I like most. Ion users might start	laughing but will stop
       immediately when	I tell them that I use my own Fvwm2 module for much
       the same	effect as Ion provides,	and I only very	rarely use the above
       key combinations	:->

       Why doesn't rxvt-unicode	read my	resources?

       Well, why, indeed? It does, in a	way very similar to other X
       applications. Most importantly, this means that if you or your OS loads
       resources into the X display (the right way to do it), rxvt-unicode
       will ignore any resource	files in your home directory. It will only
       read $HOME/.Xdefaults when no resources are attached to the display.

       If you have or use an $HOME/.Xresources file, chances are that
       resources are loaded into your X-server.	In this	case, you have to re-
       login after every change	(or run	xrdb -merge $HOME/.Xresources).

       Also consider the form resources	have to	use:

	 URxvt.resource: value

       If you want to use another form (there are lots of different ways of
       specifying resources), make sure	you understand whether and why it
       works. If unsure, use the form above.

       When I log-in to	another	system it tells	me about missing terminfo

       The terminal description	used by	rxvt-unicode is	not as widely
       available as that for xterm, or even rxvt (for which the	same problem
       often arises).

       The correct solution for	this problem is	to install the terminfo, this
       can be done by simply installing	rxvt-unicode on	the remote system as
       well (in	case you have a	nice package manager ready), or	you can
       install the terminfo database manually like this	(with ncurses infocmp.
       works as	user and root):

	  infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat	>/tmp/ti && tic	/tmp/ti"

       One some	systems	you might need to set $TERMINFO	to the full path of
       $HOME/.terminfo for this	to work.

       If you cannot or	do not want to do this,	then you can simply set
       "TERM=rxvt" or even "TERM=xterm", and live with the small number	of
       problems	arising, which includes	wrong keymapping, less and different
       colours and some	refresh	errors in fullscreen applications. It's	a nice
       quick-and-dirty workaround for rare cases, though.

       If you always want to do	this (and are fine with	the consequences) you
       can either recompile rxvt-unicode with the desired TERM value or	use a
       resource	to set it:

	  URxvt.termName: rxvt

       If you don't plan to use	rxvt (quite common...) you could also replace
       the rxvt	terminfo file with the rxvt-unicode one	and use	"TERM=rxvt".

       nano fails with "Error opening terminal:	rxvt-unicode"

       This exceptionally confusing and	useless	error message is printed by
       nano when it can't find the terminfo database. Nothing is wrong with
       your terminal, read the previous	answer for a solution.

       "tic" outputs some error	when compiling the terminfo entry.

       Most likely it's	the empty definition for "enacs=". Just	replace	it by
       "enacs=\E[0@" and try again.

       "bash"'s	readline does not work correctly under urxvt.

       See next	entry.

       I need a	termcap	file entry.

       One reason you might want this is that some distributions or operating
       systems still compile some programs using the long-obsoleted termcap
       library (Fedora's bash is one example) and rely on a termcap entry for

       You could use rxvt's termcap entry with reasonable results in many
       cases.  You can also create a termcap entry by using terminfo's infocmp
       program like this:

	  infocmp -C rxvt-unicode

       Or you could use	the termcap entry in doc/etc/rxvt-unicode.termcap,
       generated by the	command	above.

       Why does	"ls" no	longer have coloured output?

       The "ls"	in the GNU coreutils unfortunately doesn't use terminfo	to
       decide whether a	terminal has colour, but uses its own configuration
       file. Needless to say, "rxvt-unicode" is	not in its default file	(among
       with most other terminals supporting colour). Either add:

	  TERM rxvt-unicode

       to "/etc/DIR_COLORS" or simply add:

	  alias	ls='ls --color=auto'

       to your ".profile" or ".bashrc".

       Why doesn't vim/emacs etc. use the 88 colour mode?

       See next	entry.

       Why doesn't vim/emacs etc. make use of italic?

       See next	entry.

       Why are the secondary screen-related options not	working	properly?

       Make sure you are using "TERM=rxvt-unicode". Some pre-packaged
       distributions break rxvt-unicode	by setting "TERM" to "rxvt", which
       doesn't have these extra	features. Unfortunately, some of these
       furthermore fail	to even	install	the "rxvt-unicode" terminfo file, so
       you will	need to	install	it on your own (See the	question When I	log-in
       to another system it tells me about missing terminfo data? on how to do

   Encoding / Locale / Input Method Issues
       Rxvt-unicode does not seem to understand	the selected encoding?

       See next	entry.

       Unicode does not	seem to	work?

       If you encounter	strange	problems like typing an	accented character but
       getting two unrelated other characters or similar, or if	program	output
       is subtly garbled, then you should check	your locale settings.

       Rxvt-unicode must be started with the same "LC_CTYPE" setting as	the
       programs	running	in it. Often rxvt-unicode is started in	the "C"
       locale, while the login script running within the rxvt-unicode window
       changes the locale to something else, e.g. "en_GB.UTF-8". Needless to
       say, this is not	going to work, and is the most common cause for

       The best	thing is to fix	your startup environment, as you will likely
       run into	other problems.	If nothing works you can try this in your

	 printf	'\33]701;%s\007' "$LC_CTYPE"   # $LANG or $LC_ALL are worth a try, too

       If this doesn't work, then maybe	you use	a "LC_CTYPE" specification not
       supported on your systems. Some systems have a "locale" command which
       displays	this (also, "perl -e0" can be used to check locale settings,
       as it will complain loudly if it	cannot set the locale).	If it displays
       something like:

	 locale: Cannot	set LC_CTYPE to	default	locale:	...

       Then the	locale you specified is	not supported on your system.

       If nothing works	and you	are sure that everything is set	correctly then
       you will	need to	remember a little known	fact: Some programs just don't
       support locales :(

       How does	rxvt-unicode determine the encoding to use?

       See next	entry.

       Is there	an option to switch encodings?

       Unlike some other terminals, rxvt-unicode has no	encoding switch, and
       no specific "utf-8" mode, such as xterm.	In fact, it doesn't even know
       about UTF-8 or any other	encodings with respect to terminal I/O.

       The reasons is that there exists	a perfectly fine mechanism for
       selecting the encoding, doing I/O and (most important) communicating
       this to all applications	so everybody agrees on character properties
       such as width and code number. This mechanism is	the locale.
       Applications not	using that info	will have problems (for	example,
       "xterm" gets the	width of characters wrong as it	uses its own, locale-
       independent table under all locales).

       Rxvt-unicode uses the "LC_CTYPE"	locale category	to select encoding.
       All programs doing the same (that is, most) will	automatically agree in
       the interpretation of characters.

       Unfortunately, there is no system-independent way to select locales,
       nor is there a standard on how locale specifiers	will look like.

       On most systems,	the content of the "LC_CTYPE" environment variable
       contains	an arbitrary string which corresponds to an already-installed
       locale. Common names for	locales	are "en_US.UTF-8",
       "de_DE.ISO-8859-15", "ja_JP.EUC-JP", i.e. "language_country.encoding",
       but other forms (i.e. "de" or "german") are also	common.

       Rxvt-unicode ignores all	other locale categories, and except for	the
       encoding, ignores country or language-specific settings,	i.e.
       "de_DE.UTF-8" and "ja_JP.UTF-8" are the normally	same to	rxvt-unicode.

       If you want to use a specific encoding you have to make sure you	start
       rxvt-unicode with the correct "LC_CTYPE"	category.

       Can I switch locales at runtime?

       Yes, using an escape sequence. Try something like this, which sets
       rxvt-unicode's idea of "LC_CTYPE".

	 printf	'\33]701;%s\007' ja_JP.SJIS

       See also	the previous answer.

       Sometimes this capability is rather handy when you want to work in one
       locale (e.g. "de_DE.UTF-8") but some programs don't support it (e.g.
       UTF-8). For example, I use this script to start "xjdic",	which first
       switches	to a locale supported by xjdic and back	later:

	  printf '\33]701;%s\007' ja_JP.SJIS
	  xjdic	-js
	  printf '\33]701;%s\007' de_DE.UTF-8

       You can also use	xterm's	"luit" program,	which usually works fine,
       except for some locales where character width differs between program-
       and rxvt-unicode-locales.

       I have problems getting my input	method working.

       Try a search engine, as this is slightly	different for every input
       method server.

       Here is a checklist:

       - Make sure your	locale and the imLocale	are supported on your OS.
	   Try "locale -a" or check the	documentation for your OS.

       - Make sure your	locale or imLocale matches a locale supported by your
	   For example,	kinput2	does not support UTF-8 locales,	you should use
	   "ja_JP.EUC-JP" or equivalent.

       - Make sure your	XIM server is actually running.
       - Make sure the "XMODIFIERS" environment	variable is set	correctly when
       starting	rxvt-unicode.
	   When	you want to use	e.g. kinput2, it must be set to	"@im=kinput2".
	   For scim, use "@im=SCIM". You can see what input method servers are
	   running with	this command:

	      xprop -root XIM_SERVERS

       My input	method wants _some encoding_ but I want	UTF-8, what can	I do?

       You can specify separate	locales	for the	input method and the rest of
       the terminal, using the resource	"imlocale":

	  URxvt.imlocale: ja_JP.EUC-JP

       Now you can start your terminal with "LC_CTYPE=ja_JP.UTF-8" and still
       use your	input method. Please note, however, that, depending on your
       Xlib version, you may not be able to input characters outside "EUC-JP"
       in a normal way then, as	your input method limits you.

       Rxvt-unicode crashes when the X Input Method changes or exits.

       Unfortunately, this is unavoidable, as the XIM protocol is racy by
       design. Applications can	avoid some crashes at the expense of memory
       leaks, and Input	Methods	can avoid some crashes by careful ordering at
       exit time. kinput2 (and derived input methods) generally	succeeds,
       while SCIM (or similar input methods) fails. In the end,	however,
       crashes cannot be completely avoided even if both sides cooperate.

       So the only workaround is not to	kill your Input	Method Servers.

   Operating Systems / Package Maintaining
       I am maintaining	rxvt-unicode for distribution/OS XXX, any

       You should build	one binary with	the default options. configure now
       enables most useful options, and	the trend goes to making them runtime-
       switchable, too,	so there is usually no drawback	to enabling them,
       except higher disk and possibly memory usage. The perl interpreter
       should be enabled, as important functionality (menus, selection,	likely
       more in the future) depends on it.

       You should not overwrite	the "perl-ext-common" and "perl-ext" resources
       system-wide (except maybe with "defaults"). This	will result in useful
       behaviour. If your distribution aims at low memory, add an empty
       "perl-ext-common" resource to the app-defaults file. This will keep the
       perl interpreter	disabled until the user	enables	it.

       If you can/want build more binaries, I recommend	building a minimal one
       with "--disable-everything" (very useful) and a maximal one with
       "--enable-everything" (less useful, it will be very big due to a	lot of
       encodings built-in that increase	download times and are rarely used).

       I need to make it setuid/setgid to support utmp/ptys on my OS, is this

       It should be, starting with release 7.1.	You are	encouraged to properly
       install urxvt with privileges necessary for your	OS now.

       When rxvt-unicode detects that it runs setuid or	setgid,	it will	fork
       into a helper process for privileged operations (pty handling on	some
       systems,	utmp/wtmp/lastlog handling on others) and drop privileges
       immediately. This is much safer than most other terminals that keep
       privileges while	running	(but is	more relevant to urxvt,	as it contains
       things as perl interpreters, which might	be "helpful" to	attackers).

       This forking is done as the very	first within main(), which is very
       early and reduces possible bugs to initialisation code run before
       main(), or things like the dynamic loader of your system, which should
       result in very little risk.

       I am on FreeBSD and rxvt-unicode	does not seem to work at all.

       Rxvt-unicode requires the symbol	"__STDC_ISO_10646__" to	be defined in
       your compile environment, or an implementation that implements it,
       whether it defines the symbol or	not. "__STDC_ISO_10646__" requires
       that wchar_t is represented as unicode.

       As you might have guessed, FreeBSD does neither define this symbol nor
       does it support it. Instead, it uses its	own internal representation of
       wchar_t.	This is, of course, completely fine with respect to standards.

       However,	that means rxvt-unicode	only works in "POSIX", "ISO-8859-1"
       and "UTF-8" locales under FreeBSD (which	all use	Unicode	as wchar_t).

       "__STDC_ISO_10646__" is the only	sane way to support multi-language
       apps in an OS, as using a locale-dependent (and non-standardized)
       representation of wchar_t makes it impossible to	convert	between
       wchar_t (as used	by X11 and your	applications) and any other encoding
       without implementing OS-specific-wrappers for each and every locale.
       There simply are	no APIs	to convert wchar_t into	anything except	the
       current locale encoding.

       Some applications (such as the formidable mlterm) work around this by
       carrying	their own replacement functions	for character set handling
       with them, and either implementing OS-dependent hacks or	doing multiple
       conversions (which is slow and unreliable in case the OS	implements
       encodings slightly different than the terminal emulator).

       The rxvt-unicode	author insists that the	right way to fix this is in
       the system libraries once and for all, instead of forcing every app to
       carry complete replacements for them :)

       How can I use rxvt-unicode under	cygwin?

       rxvt-unicode should compile and run out of the box on cygwin, using the
       X11 libraries that come with cygwin. libW11 emulation is	no longer
       supported (and makes no sense, either, as it only supported a single
       font). I	recommend starting the X-server	in "-multiwindow" or
       "-rootless" mode	instead, which will result in similar look&feel	as the
       old libW11 emulation.

       At the time of this writing, cygwin didn't seem to support any multi-
       byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are likely
       limited to 8-bit	encodings.

       Character widths	are not	correct.

       urxvt uses the system wcwidth function to know the information about
       the width of characters,	so on systems with incorrect locale data you
       will likely get bad results. Two	notorious examples are Solaris 9,
       where single-width characters like U+2514 are reported as double-width,
       and Darwin 8, where combining chars are reported	having width 1.

       The solution is to upgrade your system or switch	to a better one. A
       possibly	working	workaround is to use a wcwidth implementation like

	       This mode should	be enabled before actually enabling mouse
	       reporting, for semi-obvious reasons.

	       The sequences received for various modes	are as follows:

		  ESC [	M o o o	   !1005, !1015	(three octets)
		  ESC [	M c c c	   1005, !1015 (three characters)
		  ESC [	Pm M	   1015	(three or more numeric parameters)

	       The first three parameters are "code", "x" and "y". Code	is the
	       numeric code as for the other modes (but	encoded	as a decimal
	       number, including the additional	offset of 32, so you have to
	       subtract	32 first), "x" and "y" are the coordinates (1|1	is the
	       upper left corner, just as with cursor positioning).

	       Example:	Shift-Button-1 press at	top row, column	80.

		  ESC [	37 ; 80	; 1 M

	       One can use this	feature	by simply enabling it and then looking
	       for parameters to the "ESC [ M" reply - if there	are any, this
	       mode is active, otherwise one of	the old	reporting styles is

	       Other (to be implemented) reply sequences will use a similar

	       coordinates for example - anybody out there who needs this?).

       General hint: if	you get	compile	errors,	then likely your configuration
       hasn't been tested well.	Either try with	"--enable-everything" or use
       the default configuration (i.e. no "--enable-xxx" or "--disable-xxx"
       switches). Of course, you should	always report when a combination
       doesn't work, so	it can be fixed. Marc Lehmann <>.


	   Add (or remove) support for all non-multichoice options listed in
	   "./configure	--help", except	for "--enable-assert" and

	   You can specify this	and then disable options you do	not like by
	   following this with the appropriate "--disable-..." arguments, or
	   you can start with a	minimal	configuration by specifying
	   "--disable-everything" and than adding just the "--enable-..."
	   arguments you want.

       --enable-xft (default: on)
	   Add support for Xft (anti-aliased, among others) fonts. Xft fonts
	   are slower and require lots of memory, but as long as you don't use
	   them, you don't pay for them.

       --enable-font-styles (default: on)
	   Add support for bold, italic	and bold italic	font styles. The fonts
	   can be set manually or automatically.

       --with-codesets=CS,... (default:	all)
	   Compile in support for additional codeset (encoding)	groups ("eu",
	   "vn"	are always compiled in,	which includes most 8-bit character
	   sets). These	codeset	tables are used	for driving X11	core fonts,
	   they	are not	required for Xft fonts,	although having	them compiled
	   in lets rxvt-unicode	choose replacement fonts more intelligently.
	   Compiling them in will make your binary bigger (all of together
	   cost	about 700kB), but it doesn't increase memory usage unless you
	   use a font requiring	one of these encodings.

	   all	    all	available codeset groups
	   zh	    common chinese encodings
	   zh_ext   rarely used	but very big chinese encodings
	   jp	    common japanese encodings
	   jp_ext   rarely used	but big	japanese encodings
	   kr	    korean encodings

       --enable-xim (default: on)
	   Add support for XIM (X Input	Method)	protocol. This allows using
	   alternative input methods (e.g. kinput2) and	will also correctly
	   set up the input for	people using dead keys or compose keys.

       --enable-unicode3 (default: off)
	   Recommended to stay off unless you really need non-BMP characters.

	   Enable direct support for displaying	unicode	codepoints above 65535
	   (the	basic multilingual page). This increases storage requirements
	   per character from 2	to 4 bytes. X11	fonts do not yet support these
	   extra characters, but Xft does.

	   Please note that rxvt-unicode can store unicode code	points >65535
	   even	without	this flag, but the number of such characters is
	   limited to a	few thousand (shared with combining characters,	see
	   next	switch), and right now rxvt-unicode cannot display them
	   (input/output and cut&paste still work, though).

       --enable-combining (default: on)
	   Enable automatic composition	of combining characters	into composite
	   characters. This is required	for proper viewing of text where
	   accents are encoded as separate unicode characters. This is done by
	   using precomposed characters	when available or creating new pseudo-
	   characters when no precomposed form exists.

	   Without --enable-unicode3, the number of additional precomposed
	   characters is somewhat limited (the 6400 private use	characters
	   will	be (ab-)used). With --enable-unicode3, no practical limit

	   This	option will also enable	storage	(but not display) of
	   characters beyond plane 0 (>65535) when --enable-unicode3 was not

	   The combining table also contains entries for arabic	presentation
	   forms, but these are	not currently used. Bug	me if you want these
	   to be used (and tell	me how these are to be used...).

       --enable-fallback[=CLASS] (default: Rxvt)
	   When	reading	resource settings, also	read settings for class	CLASS.
	   To disable resource fallback	use --disable-fallback.

       --with-res-name=NAME (default: urxvt)
	   Use the given name as default application name when reading
	   resources. Specify --with-res-name=rxvt to replace rxvt.

       --with-res-class=CLASS (default:	URxvt)
	   Use the given class as default application class when reading
	   resources. Specify --with-res-class=Rxvt to replace rxvt.

       --enable-utmp (default: on)
	   Write user and tty to utmp file (used by programs like w) at	start
	   of rxvt execution and delete	information when rxvt exits.

       --enable-wtmp (default: on)
	   Write user and tty to wtmp file (used by programs like last)	at
	   start of rxvt execution and write logout when rxvt exits.  This
	   option requires --enable-utmp to also be specified.

       --enable-lastlog	(default: on)
	   Write user and tty to lastlog file (used by programs	like
	   lastlogin) at start of rxvt execution.  This	option requires
	   --enable-utmp to also be specified.

       --enable-pixbuf (default: on)
	   Add support for GDK-PixBuf to be used for background	images.	 It
	   adds	support	for many file formats including	JPG, PNG, TIFF,	GIF,
	   XPM,	BMP, ICO and TGA.

       --enable-startup-notification (default: on)
	   Add support for freedesktop startup notifications. This allows
	   window managers to display some kind	of progress indicator during

       --enable-transparency (default: on)
	   Add support for using the root pixmap as background to simulate
	   transparency.  Note that this feature depends on libXrender and on
	   the availability of the RENDER extension in the X server.

       --enable-fading (default: on)
	   Add support for fading the text when	focus is lost.

       --enable-rxvt-scroll (default: on)
	   Add support for the original	rxvt scrollbar.

       --enable-next-scroll (default: on)
	   Add support for a NeXT-like scrollbar.

       --enable-xterm-scroll (default: on)
	   Add support for an Xterm-like scrollbar.

	   Removes any handling	of the backspace key by	us - let the X server
	   do it.

	   Removes any handling	of the delete key by us	- let the X server do

	   Removes any support for resource checking.

	   Remove support for secondary/swap screen.

       --enable-frills (default: on)
	   Add support for many	small features that are	not essential but nice
	   to have. Normally you want this, but	for very small binaries	you
	   may want to disable this.

	   A non-exhaustive list of features enabled by	"--enable-frills"
	   (possibly in	combination with other switches) is:

	     EWMH-hints	(pid, utf8 names) and protocols	(ping)
	     urgency hint
	     separate underline	colour (-underlineColor)
	     settable border widths and	borderless switch (-w, -b, -bl)
	     visual depth selection (-depth)
	     settable extra linespacing	(-lsp)
	     iso-14755 5.1 (basic) support
	     tripleclickwords (-tcw)
	     settable insecure mode (-insecure)
	     keysym remapping support
	     cursor blinking and underline cursor (-bc,	-uc)
	     XEmbed support (-embed)
	     user-pty (-pty-fd)
	     hold on exit (-hold)
	     compile in	built-in block graphics
	     skip builtin block	graphics (-sbg)
	     separate highlight	colour (-highlightColor, -highlightTextColor)
	     extended mouse reporting modes (1005 and 1015).
	     visual selection via -visual and -depth.

	   It also enables some	non-essential features otherwise disabled,
	   such	as:

	     some round-trip time optimisations
	     nearest colour allocation on pseudocolor screens
	     UTF8_STRING support for selection
	     sgr modes 90..97 and 100..107
	     backindex and forwardindex	escape sequences
	     view change/zero scrollback escape	sequences
	     locale switching escape sequence
	     window op and some	xterm/OSC escape sequences
	     rectangular selections
	     trailing space removal for	selections
	     verbose X error handling

       --enable-iso14755 (default: on)
	   Enable extended ISO 14755 support (see urxvt(1)).  Basic support
	   (section 5.1) is enabled by "--enable-frills", while	support	for
	   5.2,	5.3 and	5.4 is enabled with this switch.

       --enable-keepscrolling (default:	on)
	   Add support for continual scrolling of the display when you hold
	   the mouse button down on a scrollbar	arrow.

       --enable-selectionscrolling (default: on)
	   Add support for scrolling when the selection	moves to the top or
	   bottom of the screen.

       --enable-mousewheel (default: on)
	   Add support for scrolling via mouse wheel or	buttons	4 & 5.

       --enable-slipwheeling (default: on)
	   Add support for continual scrolling (using the mouse	wheel as an
	   accelerator)	while the control key is held down.  This option
	   requires --enable-mousewheel	to also	be specified.

       --enable-smart-resize (default: off)
	   Add smart growth/shrink behaviour when resizing.  This should keep
	   the window corner which is closest to a corner of the screen	in a
	   fixed position.

       --enable-text-blink (default: on)
	   Add support for blinking text.

       --enable-pointer-blank (default:	on)
	   Add support to have the pointer disappear when typing or inactive.

       --enable-perl (default: on)
	   Enable an embedded perl interpreter.	See the	urxvtperl(3) manpage
	   for more info on this feature, or the files in src/perl/ for	the
	   extensions that are installed by default.  The perl interpreter
	   that	is used	can be specified via the "PERL"	environment variable
	   when	running	configure. Even	when compiled in, perl will not	be
	   initialised when all	extensions have	been disabled "-pe ""
	   --perl-ext-common """, so it	should be safe to enable from a
	   resource standpoint.

       --enable-assert (default: off)
	   Enables the assertions in the code, normally	disabled. This switch
	   is only useful when developing rxvt-unicode.

       --enable-256-color (default: off)
	   Force use of	so-called 256 colour mode, to work around buggy
	   applications	that do	not support termcap/terminfo, or simply
	   improve support for applications hardcoding the xterm 256 colour

	   This	switch breaks termcap/terminfo compatibility to
	   "TERM=rxvt-unicode",	and consequently sets "TERM" to
	   "rxvt-unicode-256color" by default (doc/etc/	contains
	   termcap/terminfo definitions	for both).

	   It also results in higher memory usage and can slow down urxvt
	   dramatically	when more than six fonts are in	use by a terminal

       --with-name=NAME	(default: urxvt)
	   Set the basename for	the installed binaries,	resulting in "urxvt",
	   "urxvtd" etc.). Specify "--with-name=rxvt" to replace with "rxvt".

       --with-term=NAME	(default: rxvt-unicode)
	   Change the environmental variable for the terminal to NAME.

	   Change the environmental variable for the path to the terminfo tree
	   to PATH.

	   Use the X Window System (pretty much	default, eh?).

       Marc Lehmann <> converted	this document to pod and
       reworked	it from	the original Rxvt documentation, which was done	by
       Geoff Wing <>, who in turn used the	XTerm documentation
       and other sources.
