		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.
68		72
		73	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
		74
		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.
		77
		78	=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
		79
		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:
		82
		83	#!/bin/sh
		84	@@URXVT_NAME@@c "$@"
		85	if [ $? -eq 2 ]; then
		86	@@URXVT_NAME@@d -q -o -f
		87	@@URXVT_NAME@@c "$@"
		88	fi
		89
		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
		93	existing daemon.
		94
		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.
		96
		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.
		101
		102	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		103
		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
		109	regular xterm.
		110
		111	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
		112	snippets:

		115	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
		116	if [ ${TERM:-foo} = xterm ]; then
		117	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
		118	echo -n '^[Z'
		119	read term_id
		120	stty icanon echo
		121	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
		122	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
		123	read DISPLAY # set it in our local shell
		124	fi
		125	fi
		126
		127	=head3 How do I compile the manual pages on my own?
		128
		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

163	The Debian GNU/Linux package of rxvt-unicode in sarge contains large	221	1. Use transparent mode:
164	patches that considerably change the behaviour of rxvt-unicode. Before

166	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
167	and try to reproduce the problem. If you cannot, chances are that the
168	problems are specific to Debian GNU/Linux, in which case it should be
169	reported via the Debian Bug Tracking System (use C<reportbug> to report
170	the bug).
171		222
172	For other problems that also affect the Debian package, you can and	223	Esetroot wallpaper.jpg

175	might encounter the same issue.

177	=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?	226	That works. If you think it doesn't, you lack transparency and tinting

182	except higher disk and possibly memory usage. The perl interpreter should
183	be enabled, as important functionality (menus, selection, likely more in
184	the future) depends on it.
185		232
186	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources	233	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
187	system-wide (except maybe with C<defaults>). This will result in useful	234	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
188	behaviour. If your distribution aims at low memory, add an empty
189	C<perl-ext-common> resource to the app-defaults file. This will keep the
190	perl interpreter disabled until the user enables it.

197	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?	239	3. Use an ARGB visual:

201	+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202	secure. Also, rxvt-unicode disables some options when it detects that it
203	runs setuid or setgid, which is not nice. Besides, with the embedded perl
204	interpreter the possibility for security problems easily multiplies.

		255	by other values to change the degree of opacity. If it doesn't work and
		256	your server crashes, you got to keep the pieces.
		257
		258	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		259
		260	Most fonts were not designed for terminal use, which means that character
		261	size varies a lot. A font that is otherwise fine for terminal use might
		262	contain some characters that are simply too wide. Rxvt-unicode will avoid
		263	these characters. For characters that are just "a bit" too wide a special
		264	"careful" rendering mode is used that redraws adjacent characters.
		265
		266	All of this requires that fonts do not lie about character sizes,
		267	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		268	box, and rxvt-unicode has no way of detecting this (the correct way is to
		269	ask for the character bounding box, which unfortunately is wrong in these
		270	cases).
		271
		272	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		273	or the respective font. If you encounter this problem you might try using
		274	the C<-lsp> option to give the font more height. If that doesn't work, you
		275	might be forced to use a different font.
		276
		277	All of this is not a problem when using X11 core fonts, as their bounding
		278	box data is correct.
		279
		280	=head3 How can I keep rxvt-unicode from using reverse video so much?
		281
		282	First of all, make sure you are running with the right terminal settings
		283	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		284	make sure you have specified colours for italic and bold, as otherwise
		285	rxvt-unicode might use reverse video to simulate the effect:
		286
		287	URxvt.colorBD: white
		288	URxvt.colorIT: green
		289
		290	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		291
		292	For some unexplainable reason, some rare programs assume a very weird
		293	colour palette when confronted with a terminal with more than the standard
		294	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		295	these programs not to assume non-ISO colours without very good reasons.
		296
		297	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		298	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		299	fix colours but keep you from using other rxvt-unicode features.
		300
		301	=head3 Can I switch the fonts at runtime?
		302
		303	Yes, using an escape sequence. Try something like this, which has the same
		304	effect as using the C<-fn> switch, and takes effect immediately:
		305
		306	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		307
		308	This is useful if you e.g. work primarily with japanese (and prefer a
		309	japanese font), but you have to switch to chinese temporarily, where
		310	japanese fonts would only be in your way.
		311
		312	You can think of this as a kind of manual ISO-2022 switching.
		313
		314	=head3 Why do italic characters look as if clipped?
		315
		316	Many fonts have difficulties with italic characters and hinting. For
		317	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		318	Mono> completely fails in its italic face. A workaround might be to
		319	enable freetype autohinting, i.e. like this:
		320
		321	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		322	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		323
		324	=head3 Can I speed up Xft rendering somehow?
		325
		326	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		327	it is simply slow. If you still want Xft fonts you might try to disable
		328	antialiasing (by appending C<:antialias=false>), which saves lots of
		329	memory and also speeds up rendering considerably.
		330
		331	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		332
		333	Rxvt-unicode will use whatever you specify as a font. If it needs to
		334	fall back to its default font search list it will prefer X11 core
		335	fonts, because they are small and fast, and then use Xft fonts. It has
		336	antialiasing disabled for most of them, because the author thinks they
		337	look best that way.
		338
		339	If you want antialiasing, you have to specify the fonts manually.
		340
		341	=head3 What's with this bold/blink stuff?
		342
		343	If no bold colour is set via C<colorBD:>, bold will invert text using the
		344	standard foreground colour.
		345
		346	For the standard background colour, blinking will actually make the
		347	text blink when compiled with C<--enable-blinking>. with standard
		348	colours. Without C<--enable-blinking>, the blink attribute will be
		349	ignored.
		350
		351	On ANSI colours, bold/blink attributes are used to set high-intensity
		352	foreground/background colors.
		353
		354	color0-7 are the low-intensity colors.
		355
		356	color8-15 are the corresponding high-intensity colors.
		357
		358	=head3 I don't like the screen colors. How do I change them?
		359
		360	You can change the screen colors at run-time using F<~/.Xdefaults>
		361	resources (or as long-options).
		362
		363	Here are values that are supposed to resemble a VGA screen,
		364	including the murky brown that passes for low-intensity yellow:
		365
		366	URxvt.color0: #000000
		367	URxvt.color1: #A80000
		368	URxvt.color2: #00A800
		369	URxvt.color3: #A8A800
		370	URxvt.color4: #0000A8
		371	URxvt.color5: #A800A8
		372	URxvt.color6: #00A8A8
		373	URxvt.color7: #A8A8A8
		374
		375	URxvt.color8: #000054
		376	URxvt.color9: #FF0054
		377	URxvt.color10: #00FF54
		378	URxvt.color11: #FFFF54
		379	URxvt.color12: #0000FF
		380	URxvt.color13: #FF00FF
		381	URxvt.color14: #00FFFF
		382	URxvt.color15: #FFFFFF
		383
		384	And here is a more complete set of non-standard colors.
		385
		386	URxvt.cursorColor: #dc74d1
		387	URxvt.pointerColor: #dc74d1
		388	URxvt.background: #0e0e0e
		389	URxvt.foreground: #4ad5e1
		390	URxvt.color0: #000000
		391	URxvt.color8: #8b8f93
		392	URxvt.color1: #dc74d1
		393	URxvt.color9: #dc74d1
		394	URxvt.color2: #0eb8c7
		395	URxvt.color10: #0eb8c7
		396	URxvt.color3: #dfe37e
		397	URxvt.color11: #dfe37e
		398	URxvt.color5: #9e88f0
		399	URxvt.color13: #9e88f0
		400	URxvt.color6: #73f7ff
		401	URxvt.color14: #73f7ff
		402	URxvt.color7: #e1dddd
		403	URxvt.color15: #e1dddd
		404
		405	They have been described (not by me) as "pretty girly".
		406
		407	=head3 Why do some characters look so much different than others?
		408
		409	See next entry.
		410
		411	=head3 How does rxvt-unicode choose fonts?
		412
		413	Most fonts do not contain the full range of Unicode, which is
		414	fine. Chances are that the font you (or the admin/package maintainer of
		415	your system/os) have specified does not cover all the characters you want
		416	to display.
		417
		418	B<rxvt-unicode> makes a best-effort try at finding a replacement
		419	font. Often the result is fine, but sometimes the chosen font looks
		420	bad/ugly/wrong. Some fonts have totally strange characters that don't
		421	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		422	intelligence to detect that a specific glyph is wrong: it has to believe
		423	the font that the characters it claims to contain indeed look correct.
		424
		425	In that case, select a font of your taste and add it to the font list,
		426	e.g.:
		427
		428	@@URXVT_NAME@@ -fn basefont,font2,font3...
		429
		430	When rxvt-unicode sees a character, it will first look at the base
		431	font. If the base font does not contain the character, it will go to the
		432	next font, and so on. Specifying your own fonts will also speed up this
		433	search and use less resources within rxvt-unicode and the X-server.
		434
		435	The only limitation is that none of the fonts may be larger than the base
		436	font, as the base font defines the terminal character cell size, which
		437	must be the same due to the way terminals work.
		438
		439	=head3 Why do some chinese characters look so different than others?
		440
		441	This is because there is a difference between script and language --
		442	rxvt-unicode does not know which language the text that is output is,
		443	as it only knows the unicode character codes. If rxvt-unicode first
		444	sees a japanese/chinese character, it might choose a japanese font for
		445	display. Subsequent japanese characters will use that font. Now, many
		446	chinese characters aren't represented in japanese fonts, so when the first
		447	non-japanese character comes up, rxvt-unicode will look for a chinese font
		448	-- unfortunately at this point, it will still use the japanese font for
		449	chinese characters that are also in the japanese font.
		450
		451	The workaround is easy: just tag a chinese font at the end of your font
		452	list (see the previous question). The key is to view the font list as
		453	a preference list: If you expect more japanese, list a japanese font
		454	first. If you expect more chinese, put a chinese font first.
		455
		456	In the future it might be possible to switch language preferences at
		457	runtime (the internal data structure has no problem with using different
		458	fonts for the same character at the same time, but no interface for this
		459	has been designed yet).
		460
		461	Until then, you might get away with switching fonts at runtime (see L<Can
		462	I switch the fonts at runtime?> later in this document).
		463
		464	=head3 How can I make mplayer display video correctly?
		465
		466	We are working on it, in the meantime, as a workaround, use something like:
		467
		468	@@URXVT_NAME@@ -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
		469
		470
		471	=head2 Keyboard, Mouse & User Interaction
		472
		473	=head3 The new selection selects pieces that are too big, how can I select single words?
		474
		475	If you want to select e.g. alphanumeric words, you can use the following
		476	setting:
		477
		478	URxvt.selection.pattern-0: ([[:word:]]+)
		479
		480	If you click more than twice, the selection will be extended
		481	more and more.
		482
		483	To get a selection that is very similar to the old code, try this pattern:
		484
		485	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		486
		487	Please also note that the I<LeftClick Shift-LeftClik> combination also
		488	selects words like the old code.
		489
		490	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		491
		492	You can disable the perl extension completely by setting the
		493	B<perl-ext-common> resource to the empty string, which also keeps
		494	rxvt-unicode from initialising perl, saving memory.
		495
		496	If you only want to disable specific features, you first have to
		497	identify which perl extension is responsible. For this, read the section
		498	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		499	example, to disable the B<selection-popup> and B<option-popup>, specify
		500	this B<perl-ext-common> resource:
		501
		502	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		503
		504	This will keep the default extensions, but disable the two popup
		505	extensions. Some extensions can also be configured, for example,
		506	scrollback search mode is triggered by B<M-s>. You can move it to any
		507	other combination either by setting the B<searchable-scrollback> resource:
		508
		509	URxvt.searchable-scrollback: CM-s
		510
		511	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		512
		513	See next entry.
		514
		515	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		516
		517	These are caused by the C<readline> perl extension. Under normal
		518	circumstances, it will move your cursor around when you click into the
		519	line that contains it. It tries hard not to do this at the wrong moment,
		520	but when running a program that doesn't parse cursor movements or in some
		521	cases during rlogin sessions, it fails to detect this properly.
		522
		523	You can permanently switch this feature off by disabling the C<readline>
		524	extension:
		525
		526	URxvt.perl-ext-common: default,-readline
		527
		528	=head3 My numerical keypad acts weird and generates differing output?
		529
		530	Some Debian GNUL/Linux users seem to have this problem, although no
		531	specific details were reported so far. It is possible that this is caused
		532	by the wrong C<TERM> setting, although the details of whether and how
		533	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		534	keymap. See the answer to the previous question, and please report if that
		535	helped.
		536
		537	=head3 My Compose (Multi_key) key is no longer working.
		538
		539	The most common causes for this are that either your locale is not set
		540	correctly, or you specified a B<preeditStyle> that is not supported by
		541	your input method. For example, if you specified B<OverTheSpot> and
		542	your input method (e.g. the default input method handling Compose keys)
		543	does not support this (for instance because it is not visual), then
		544	rxvt-unicode will continue without an input method.
		545
		546	In this case either do not specify a B<preeditStyle> or specify more than
		547	one pre-edit style, such as B<OverTheSpot,Root,None>.
		548
		549	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		550
		551	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		552	international keyboards) or simply use ISO 14755 support to your
		553	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		554	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		555	character and so on.
		556
		557	=head3 Mouse cut/paste suddenly no longer works.
		558
		559	Make sure that mouse reporting is actually turned off since killing
		560	some editors prematurely may leave the mouse in mouse report mode. I've
		561	heard that tcsh may use mouse reporting unless it otherwise specified. A
		562	quick check is to see if cut/paste works when the Alt or Shift keys are
		563	depressed.
		564
		565	=head3 What's with the strange Backspace/Delete key behaviour?
		566
		567	Assuming that the physical Backspace key corresponds to the
		568	Backspace keysym (not likely for Linux ... see the following
		569	question) there are two standard values that can be used for
		570	Backspace: C<^H> and C<^?>.
		571
		572	Historically, either value is correct, but rxvt-unicode adopts the debian
		573	policy of using C<^?> when unsure, because it's the one and only correct
		574	choice :).
		575
		576	Rxvt-unicode tries to inherit the current stty settings and uses the value
		577	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		578	started from a terminal (say, from a menu or by remote shell), then the
		579	system value of `erase', which corresponds to CERASE in <termios.h>, will
		580	be used (which may not be the same as your stty setting).
		581
		582	For starting a new rxvt-unicode:
		583
		584	# use Backspace = ^H
		585	$ stty erase ^H
		586	$ @@URXVT_NAME@@
		587
		588	# use Backspace = ^?
		589	$ stty erase ^?
		590	$ @@URXVT_NAME@@
		591
		592	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		593
		594	For an existing rxvt-unicode:
		595
		596	# use Backspace = ^H
		597	$ stty erase ^H
		598	$ echo -n "^[[36h"
		599
		600	# use Backspace = ^?
		601	$ stty erase ^?
		602	$ echo -n "^[[36l"
		603
		604	This helps satisfy some of the Backspace discrepancies that occur, but
		605	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		606	properly reflects that.
		607
		608	The Delete key is a another casualty of the ill-defined Backspace problem.
		609	To avoid confusion between the Backspace and Delete keys, the Delete
		610	key has been assigned an escape sequence to match the vt100 for Execute
		611	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		612
		613	Some other Backspace problems:
		614
		615	some editors use termcap/terminfo,
		616	some editors (vim I'm told) expect Backspace = ^H,
		617	GNU Emacs (and Emacs-like editors) use ^H for help.
		618
		619	Perhaps someday this will all be resolved in a consistent manner.
		620
		621	=head3 I don't like the key-bindings. How do I change them?
		622
		623	There are some compile-time selections available via configure. Unless
		624	you have run "configure" with the C<--disable-resources> option you can
		625	use the `keysym' resource to alter the keystrings associated with keysyms.
		626
		627	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
		628
		629	URxvt.keysym.Home: \033[1~

		648	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
		649
		650	See some more examples in the documentation for the B<keysym> resource.
		651
		652	=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
		653
		654	KP_Insert == Insert
		655	F22 == Print
		656	F27 == Home
		657	F29 == Prior
		658	F33 == End
		659	F35 == Next
		660
		661	Rather than have rxvt-unicode try to accommodate all the various possible
		662	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		663	required for your particular machine.
		664
		665
		666	=head2 Terminal Configuration
		667
		668	=head3 Can I see a typical configuration?
		669
		670	The default configuration tries to be xterm-like, which I don't like that
		671	much, but it's least surprise to regular users.
		672
		673	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		674	time into customising your terminal. To get you started, here is the
		675	author's .Xdefaults entries, with comments on what they do. It's certainly
		676	not I<typical>, but what's typical...
		677
		678	URxvt.cutchars: "()*,<>[]{}|'
		679	URxvt.print-pipe: cat >/tmp/xxx
		680
		681	These are just for testing stuff.
		682
		683	URxvt.imLocale: ja_JP.UTF-8
		684	URxvt.preeditType: OnTheSpot,None
		685
		686	This tells rxvt-unicode to use a special locale when communicating with
		687	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		688	type, which requires the C<xim-onthespot> perl extension but rewards me
		689	with correct-looking fonts.
		690
		691	URxvt.perl-lib: /root/lib/urxvt
		692	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard

		694	URxvt.selection.pattern-1: ^(/[^:]+):\
		695	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		696	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		697
		698	This is my perl configuration. The first two set the perl library
		699	directory and also tells urxvt to use a large number of extensions. I
		700	develop for myself mostly, so I actually use most of the extensions I
		701	write.
		702
		703	The selection stuff mainly makes the selection perl-error-message aware
		704	and tells it to convert perl error messages into vi-commands to load the
		705	relevant file and go tot he error line number.
		706
		707	URxvt.scrollstyle: plain
		708	URxvt.secondaryScroll: true
		709
		710	As the documentation says: plain is the preferred scrollbar for the
		711	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		712	apps, like screen, so lines scrolled out of screen end up in urxvt's
		713	scrollback buffer.
		714
		715	URxvt.background: #000000
		716	URxvt.foreground: gray90
		717	URxvt.color7: gray90
		718	URxvt.colorBD: #ffffff
		719	URxvt.cursorColor: #e0e080
		720	URxvt.throughColor: #8080f0
		721	URxvt.highlightColor: #f0f0f0
		722
		723	Some colours. Not sure which ones are being used or even non-defaults, but
		724	these are in my .Xdefaults. Most notably, they set foreground/background
		725	to light gray/black, and also make sure that the colour 7 matches the
		726	default foreground colour.
		727
		728	URxvt.underlineColor: yellow
		729
		730	Another colour, makes underline lines look different. Sometimes hurts, but
		731	is mostly a nice effect.
		732
		733	URxvt.geometry: 154x36
		734	URxvt.loginShell: false
		735	URxvt.meta: ignore
		736	URxvt.utmpInhibit: true
		737
		738	Uh, well, should be mostly self-explanatory. By specifying some defaults
		739	manually, I can quickly switch them for testing.
		740
		741	URxvt.saveLines: 8192
		742
		743	A large scrollback buffer is essential. Really.
		744
		745	URxvt.mapAlert: true
		746
		747	The only case I use it is for my IRC window, which I like to keep
		748	iconified till people msg me (which beeps).
		749
		750	URxvt.visualBell: true
		751
		752	The audible bell is often annoying, especially when in a crowd.

		771
		772	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		773	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		774	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		775	font (different glyphs for C<;> and many other harmless characters),
		776	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		777	bold version has less chars than the medium version, so I use it for rare
		778	characters, too. When editing sources with vim, I use italic for comments
		779	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		780
		781	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		782	purposes, it works, and gives a different look, as my normal (Non-bold)
		783	font is already bold, and I want to see a difference between bold and
		784	normal fonts.
		785
		786	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		787	class name. Thats because I use different configs for different purposes,
		788	for example, my IRC window is started with C<-name IRC>, and uses these
		789	defaults:
		790
		791	IRC*title: IRC
		792	IRC*geometry: 87x12+535+542

		800
		801	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		802	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		803	stuff while keeping a very small window. If somebody pastes something
		804	complicated (e.g. japanese), I temporarily switch to a larger font.
		805
		806	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		807	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>

		825	applications. Most importantly, this means that if you or your OS loads
		826	resources into the X display (the right way to do it), rxvt-unicode will
		827	ignore any resource files in your home directory. It will only read
		828	F<$HOME/.Xdefaults> when no resources are attached to the display.
		829
		830	If you have or use an F<$HOME/.Xresources> file, chances are that
		831	resources are loaded into your X-server. In this case, you have to
		832	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		833
		834	Also consider the form resources have to use:
		835
		836	URxvt.resource: value
		837
		838	If you want to use another form (there are lots of different ways of

388	=item Why do some chinese characters look so different than others?
389
390	This is because there is a difference between script and language --
391	rxvt-unicode does not know which language the text that is output is,
392	as it only knows the unicode character codes. If rxvt-unicode first
393	sees a japanese/chinese character, it might choose a japanese font for
394	display. Subsequent japanese characters will use that font. Now, many
395	chinese characters aren't represented in japanese fonts, so when the first
396	non-japanese character comes up, rxvt-unicode will look for a chinese font
397	-- unfortunately at this point, it will still use the japanese font for
398	chinese characters that are also in the japanese font.
399
400	The workaround is easy: just tag a chinese font at the end of your font
401	list (see the previous question). The key is to view the font list as
402	a preference list: If you expect more japanese, list a japanese font
403	first. If you expect more chinese, put a chinese font first.
404
405	In the future it might be possible to switch language preferences at
406	runtime (the internal data structure has no problem with using different
407	fonts for the same character at the same time, but no interface for this
408	has been designed yet).
409
410	Until then, you might get away with switching fonts at runtime (see L<Can
411	I switch the fonts at runtime?> later in this document).
412
413	=item Why does rxvt-unicode sometimes leave pixel droppings?
414
415	Most fonts were not designed for terminal use, which means that character
416	size varies a lot. A font that is otherwise fine for terminal use might
417	contain some characters that are simply too wide. Rxvt-unicode will avoid
418	these characters. For characters that are just "a bit" too wide a special
419	"careful" rendering mode is used that redraws adjacent characters.
420
421	All of this requires that fonts do not lie about character sizes,
422	however: Xft fonts often draw glyphs larger than their acclaimed bounding
423	box, and rxvt-unicode has no way of detecting this (the correct way is to

		1106	=head2 Operating Systems / Package Maintaining
		1107
		1108	=head3 I am using Debian GNU/Linux and have a problem...
		1109
		1110	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		1111	patches that considerably change the behaviour of rxvt-unicode (but
		1112	unfortunately this notice has been removed). Before reporting a bug to
		1113	the original rxvt-unicode author please download and install the genuine
		1114	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		1115	the problem. If you cannot, chances are that the problems are specific to
		1116	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		1117	Tracking System (use C<reportbug> to report the bug).
		1118
		1119	For other problems that also affect the Debian package, you can and
		1120	probably should use the Debian BTS, too, because, after all, it's also a
		1121	bug in the Debian version and it serves as a reminder for other users that
		1122	might encounter the same issue.
		1123
		1124	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1125
		1126	You should build one binary with the default options. F<configure>
		1127	now enables most useful options, and the trend goes to making them
		1128	runtime-switchable, too, so there is usually no drawback to enabling them,
		1129	except higher disk and possibly memory usage. The perl interpreter should
		1130	be enabled, as important functionality (menus, selection, likely more in
		1131	the future) depends on it.
		1132
		1133	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1134	system-wide (except maybe with C<defaults>). This will result in useful
		1135	behaviour. If your distribution aims at low memory, add an empty
		1136	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1137	perl interpreter disabled until the user enables it.
		1138
		1139	If you can/want build more binaries, I recommend building a minimal
		1140	one with C<--disable-everything> (very useful) and a maximal one with
		1141	C<--enable-everything> (less useful, it will be very big due to a lot of
		1142	encodings built-in that increase download times and are rarely used).
		1143
		1144	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1145
		1146	It should be, starting with release 7.1. You are encouraged to properly
		1147	install urxvt with privileges necessary for your OS now.
		1148
		1149	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1150	into a helper process for privileged operations (pty handling on some
		1151	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1152	immediately. This is much safer than most other terminals that keep
		1153	privileges while running (but is more relevant to urxvt, as it contains
		1154	things as perl interpreters, which might be "helpful" to attackers).
		1155
		1156	This forking is done as the very first within main(), which is very early
		1157	and reduces possible bugs to initialisation code run before main(), or
		1158	things like the dynamic loader of your system, which should result in very
		1159	little risk.

535		1207
536	=item Is there an option to switch encodings?	1208	urxvt uses the system wcwidth function to know the information about
		1209	the width of characters, so on systems with incorrect locale data you
		1210	will likely get bad results. Two notorious examples are Solaris 9,
		1211	where single-width characters like U+2514 are reported as double-width,
		1212	and Darwin 8, where combining chars are reported having width 1.

540	UTF-8 or any other encodings with respect to terminal I/O.
541		1216
542	The reasons is that there exists a perfectly fine mechanism for selecting	1217	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
543	the encoding, doing I/O and (most important) communicating this to all
544	applications so everybody agrees on character properties such as width
545	and code number. This mechanism is the I<locale>. Applications not using
546	that info will have problems (for example, C<xterm> gets the width of
547	characters wrong as it uses it's own, locale-independent table under all
548	locales).
549		1218
550	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
551	programs doing the same (that is, most) will automatically agree in the
552	interpretation of characters.
553
554	Unfortunately, there is no system-independent way to select locales, nor
555	is there a standard on how locale specifiers will look like.
556
557	On most systems, the content of the C<LC_CTYPE> environment variable
558	contains an arbitrary string which corresponds to an already-installed
559	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
560	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
561	(i.e. C<de> or C<german>) are also common.
562
563	Rxvt-unicode ignores all other locale categories, and except for
564	the encoding, ignores country or language-specific settings,
565	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
566	rxvt-unicode.
567
568	If you want to use a specific encoding you have to make sure you start
569	rxvt-unicode with the correct C<LC_CTYPE> category.
570
571	=item Can I switch locales at runtime?
572
573	Yes, using an escape sequence. Try something like this, which sets
574	rxvt-unicode's idea of C<LC_CTYPE>.
575
576	printf '\e]701;%s\007' ja_JP.SJIS
577
578	See also the previous answer.
579
580	Sometimes this capability is rather handy when you want to work in
581	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
582	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
583	first switches to a locale supported by xjdic and back later:
584
585	printf '\e]701;%s\007' ja_JP.SJIS
586	xjdic -js
587	printf '\e]701;%s\007' de_DE.UTF-8
588
589	You can also use xterm's C<luit> program, which usually works fine, except
590	for some locales where character width differs between program- and
591	rxvt-unicode-locales.
592
593	=item Can I switch the fonts at runtime?
594
595	Yes, using an escape sequence. Try something like this, which has the same
596	effect as using the C<-fn> switch, and takes effect immediately:
597
598	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
599
600	This is useful if you e.g. work primarily with japanese (and prefer a
601	japanese font), but you have to switch to chinese temporarily, where
602	japanese fonts would only be in your way.
603
604	You can think of this as a kind of manual ISO-2022 switching.
605
606	=item Why do italic characters look as if clipped?
607
608	Many fonts have difficulties with italic characters and hinting. For
609	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
610	Mono> completely fails in it's italic face. A workaround might be to
611	enable freetype autohinting, i.e. like this:
612
613	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
614	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
615
616	=item My input method wants <some encoding> but I want UTF-8, what can I do?
617
618	You can specify separate locales for the input method and the rest of the
619	terminal, using the resource C<imlocale>:
620
621	URxvt.imlocale: ja_JP.EUC-JP
622
623	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
624	use your input method. Please note, however, that you will not be able to
625	input characters outside C<EUC-JP> in a normal way then, as your input
626	method limits you.
627
628	=item Rxvt-unicode crashes when the X Input Method changes or exits.
629
630	Unfortunately, this is unavoidable, as the XIM protocol is racy by
631	design. Applications can avoid some crashes at the expense of memory
632	leaks, and Input Methods can avoid some crashes by careful ordering at
633	exit time. B<kinput2> (and derived input methods) generally succeeds,
634	while B<SCIM> (or similar input methods) fails. In the end, however,
635	crashes cannot be completely avoided even if both sides cooperate.
636
637	So the only workaround is not to kill your Input Method Servers.
638
639	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
640
641	Rxvt-unicode tries to obey the rule of not charging you for something you
642	don't use. One thing you should try is to configure out all settings that
643	you don't need, for example, Xft support is a resource hog by design,
644	when used. Compiling it out ensures that no Xft font will be loaded
645	accidentally when rxvt-unicode tries to find a font for your characters.
646
647	Also, many people (me included) like large windows and even larger
648	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
649	6 bytes per screen cell. For a 160x?? window this amounts to almost a
650	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
651	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
652	rxvt-unicode then uses 8 bytes per screen cell.
653
654	=item Can I speed up Xft rendering somehow?
655
656	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
657	it is simply slow. If you still want Xft fonts you might try to disable
658	antialiasing (by appending C<:antialias=false>), which saves lots of
659	memory and also speeds up rendering considerably.
660
661	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
662
663	Rxvt-unicode will use whatever you specify as a font. If it needs to
664	fall back to it's default font search list it will prefer X11 core
665	fonts, because they are small and fast, and then use Xft fonts. It has
666	antialiasing disabled for most of them, because the author thinks they
667	look best that way.
668
669	If you want antialiasing, you have to specify the fonts manually.
670
671	=item Mouse cut/paste suddenly no longer works.
672
673	Make sure that mouse reporting is actually turned off since killing
674	some editors prematurely may leave the mouse in mouse report mode. I've
675	heard that tcsh may use mouse reporting unless it otherwise specified. A
676	quick check is to see if cut/paste works when the Alt or Shift keys are
677	depressed.
678
679	=item What's with this bold/blink stuff?
680
681	If no bold colour is set via C<colorBD:>, bold will invert text using the
682	standard foreground colour.
683
684	For the standard background colour, blinking will actually make the
685	text blink when compiled with C<--enable-blinking>. with standard
686	colours. Without C<--enable-blinking>, the blink attribute will be
687	ignored.
688
689	On ANSI colours, bold/blink attributes are used to set high-intensity
690	foreground/background colors.
691
692	color0-7 are the low-intensity colors.
693
694	color8-15 are the corresponding high-intensity colors.
695
696	=item I don't like the screen colors. How do I change them?

753	question) there are two standard values that can be used for
754	Backspace: C<^H> and C<^?>.
755
756	Historically, either value is correct, but rxvt-unicode adopts the debian
757	policy of using C<^?> when unsure, because it's the one only only correct
758	choice :).
759
760	Rxvt-unicode tries to inherit the current stty settings and uses the value
761	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
762	started from a terminal (say, from a menu or by remote shell), then the
763	system value of `erase', which corresponds to CERASE in <termios.h>, will

784	# use Backspace = ^?
785	$ stty erase ^?
786	$ echo -n "^[[36l"
787
788	This helps satisfy some of the Backspace discrepancies that occur, but
789	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
790	properly reflects that.
791
792	The Delete key is a another casualty of the ill-defined Backspace problem.
793	To avoid confusion between the Backspace and Delete keys, the Delete
794	key has been assigned an escape sequence to match the vt100 for Execute
795	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
796
797	Some other Backspace problems:
798
799	some editors use termcap/terminfo,
800	some editors (vim I'm told) expect Backspace = ^H,
801	GNU Emacs (and Emacs-like editors) use ^H for help.
802
803	Perhaps someday this will all be resolved in a consistent manner.
804
805	=item I don't like the key-bindings. How do I change them?
806
807	There are some compile-time selections available via configure. Unless
808	you have run "configure" with the C<--disable-resources> option you can
809	use the `keysym' resource to alter the keystrings associated with keysyms.
810
811	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>

836	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
837	How do I make use of them? For example, the Sun Keyboard type 4
838	has the following mappings that rxvt-unicode doesn't recognize.
839
840	KP_Insert == Insert
841	F22 == Print
842	F27 == Home
843	F29 == Prior
844	F33 == End
845	F35 == Next
846
847	Rather than have rxvt-unicode try to accommodate all the various possible
848	keyboard mappings, it is better to use `xmodmap' to remap the keys as
849	required for your particular machine.
850
851	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
852	I need this to decide about setting colors etc.
853
854	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
855	check and see if that is set. Note that several programs, JED, slrn,
856	Midnight Commander automatically check this variable to decide whether or
857	not to use color.
858
859	=item How do I set the correct, full IP address for the DISPLAY variable?
860
861	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
862	insecure mode then it is possible to use the following shell script
863	snippets to correctly set the display. If your version of rxvt-unicode
864	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
865	the COLORTERM variable can be used to distinguish rxvt-unicode from a
866	regular xterm.
867
868	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
869	snippets:
870
871	# Bourne/Korn/POSIX family of shells:
872	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
873	if [ ${TERM:-foo} = xterm ]; then
874	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
875	echo -n '^[Z'

884	=item How do I compile the manual pages for myself?
885
886	You need to have a recent version of perl installed as F</usr/bin/perl>,
887	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
888	the doc subdirectory and enter C<make alldoc>.
