		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

161	=item I am using Debian GNU/Linux and have a problem...	218	Here are four ways to get transparency. B<Do> read the manpage and option
		219	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
162		220
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
165	reporting a bug to the original rxvt-unicode author please download and
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
173	probably should use the Debian BTS, too, because, after all, it's also a	224	@@URXVT_NAME@@ -tr -tint red -sh 40
174	bug in the Debian version and it serves as a reminder for other users that
175	might encounter the same issue.
176		225
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
		227	support, or you are unable to read.
178		228
179	You should build one binary with the default options. F<configure>	229	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
180	now enables most useful options, and the trend goes to making them	230	to use effects other than tinting and shading: Just shade/tint/whatever
181	runtime-switchable, too, so there is usually no drawback to enbaling them,	231	your picture with gimp or any other tool:
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.
191		235
192	If you can/want build more binaries, I recommend building a minimal	236	That works. If you think it doesn't, you lack AfterImage support, or you

194	C<--enable-everything> (less useful, it will be very big due to a lot of
195	encodings built-in that increase download times and are rarely used).
196		238
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:

200	install urxvt with privileges necessary for your OS now.
201		242
202	When rxvt-unicode detects that it runs setuid or setgid, it will fork	243	This requires XFT support, and the support of your X-server. If that
203	into a helper process for privileged operations (pty handling on some	244	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
204	systems, utmp/wtmp/lastlog handling on others) and drop privileges	245	there yet, no matter what they claim. Rxvt-Unicode contains the necessary

207	things as perl interpreters, which might be "helpful" to attackers).
208		248
209	This forking is done as the very first within main(), which is very early	249	4. Use xcompmgr and let it do the job:
210	and reduces possible bugs to initialisation code run before main(), or
211	things like the dynamic loader of your system, which should result in very
212	little risk.

		251	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		252	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		253
		254	Then click on a window you want to make transparent. Replace C<0xc0000000>
		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
		347	the text blink when compiled with C<--enable-text-blink>. Without
		348	C<--enable-text-blink>, the blink attribute will be ignored.
		349
		350	On ANSI colours, bold/blink attributes are used to set high-intensity
		351	foreground/background colors.
		352
		353	color0-7 are the low-intensity colors.
		354
		355	color8-15 are the corresponding high-intensity colors.
		356
		357	=head3 I don't like the screen colors. How do I change them?
		358
		359	You can change the screen colors at run-time using F<~/.Xdefaults>
		360	resources (or as long-options).
		361
		362	Here are values that are supposed to resemble a VGA screen,
		363	including the murky brown that passes for low-intensity yellow:
		364
		365	URxvt.color0: #000000
		366	URxvt.color1: #A80000
		367	URxvt.color2: #00A800
		368	URxvt.color3: #A8A800
		369	URxvt.color4: #0000A8
		370	URxvt.color5: #A800A8
		371	URxvt.color6: #00A8A8
		372	URxvt.color7: #A8A8A8
		373
		374	URxvt.color8: #000054
		375	URxvt.color9: #FF0054
		376	URxvt.color10: #00FF54
		377	URxvt.color11: #FFFF54
		378	URxvt.color12: #0000FF
		379	URxvt.color13: #FF00FF
		380	URxvt.color14: #00FFFF
		381	URxvt.color15: #FFFFFF
		382
		383	And here is a more complete set of non-standard colors.
		384
		385	URxvt.cursorColor: #dc74d1
		386	URxvt.pointerColor: #dc74d1
		387	URxvt.background: #0e0e0e
		388	URxvt.foreground: #4ad5e1
		389	URxvt.color0: #000000
		390	URxvt.color8: #8b8f93
		391	URxvt.color1: #dc74d1
		392	URxvt.color9: #dc74d1
		393	URxvt.color2: #0eb8c7
		394	URxvt.color10: #0eb8c7
		395	URxvt.color3: #dfe37e
		396	URxvt.color11: #dfe37e
		397	URxvt.color5: #9e88f0
		398	URxvt.color13: #9e88f0
		399	URxvt.color6: #73f7ff
		400	URxvt.color14: #73f7ff
		401	URxvt.color7: #e1dddd
		402	URxvt.color15: #e1dddd
		403
		404	They have been described (not by me) as "pretty girly".
		405
		406	=head3 Why do some characters look so much different than others?
		407
		408	See next entry.
		409
		410	=head3 How does rxvt-unicode choose fonts?
		411
		412	Most fonts do not contain the full range of Unicode, which is
		413	fine. Chances are that the font you (or the admin/package maintainer of
		414	your system/os) have specified does not cover all the characters you want
		415	to display.
		416
		417	B<rxvt-unicode> makes a best-effort try at finding a replacement
		418	font. Often the result is fine, but sometimes the chosen font looks
		419	bad/ugly/wrong. Some fonts have totally strange characters that don't
		420	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		421	intelligence to detect that a specific glyph is wrong: it has to believe
		422	the font that the characters it claims to contain indeed look correct.
		423
		424	In that case, select a font of your taste and add it to the font list,
		425	e.g.:
		426
		427	@@URXVT_NAME@@ -fn basefont,font2,font3...
		428
		429	When rxvt-unicode sees a character, it will first look at the base
		430	font. If the base font does not contain the character, it will go to the
		431	next font, and so on. Specifying your own fonts will also speed up this
		432	search and use less resources within rxvt-unicode and the X-server.
		433
		434	The only limitation is that none of the fonts may be larger than the base
		435	font, as the base font defines the terminal character cell size, which
		436	must be the same due to the way terminals work.
		437
		438	=head3 Why do some chinese characters look so different than others?
		439
		440	This is because there is a difference between script and language --
		441	rxvt-unicode does not know which language the text that is output is,
		442	as it only knows the unicode character codes. If rxvt-unicode first
		443	sees a japanese/chinese character, it might choose a japanese font for
		444	display. Subsequent japanese characters will use that font. Now, many
		445	chinese characters aren't represented in japanese fonts, so when the first
		446	non-japanese character comes up, rxvt-unicode will look for a chinese font
		447	-- unfortunately at this point, it will still use the japanese font for
		448	chinese characters that are also in the japanese font.
		449
		450	The workaround is easy: just tag a chinese font at the end of your font
		451	list (see the previous question). The key is to view the font list as
		452	a preference list: If you expect more japanese, list a japanese font
		453	first. If you expect more chinese, put a chinese font first.
		454
		455	In the future it might be possible to switch language preferences at
		456	runtime (the internal data structure has no problem with using different
		457	fonts for the same character at the same time, but no interface for this
		458	has been designed yet).
		459
		460	Until then, you might get away with switching fonts at runtime (see L<Can
		461	I switch the fonts at runtime?> later in this document).
		462
		463	=head3 How can I make mplayer display video correctly?
		464
		465	We are working on it, in the meantime, as a workaround, use something like:
		466
		467	@@URXVT_NAME@@ -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
		468
		469
		470	=head2 Keyboard, Mouse & User Interaction
		471
		472	=head3 The new selection selects pieces that are too big, how can I select single words?
		473
		474	If you want to select e.g. alphanumeric words, you can use the following
		475	setting:
		476
		477	URxvt.selection.pattern-0: ([[:word:]]+)
		478
		479	If you click more than twice, the selection will be extended
		480	more and more.
		481
		482	To get a selection that is very similar to the old code, try this pattern:
		483
		484	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		485
		486	Please also note that the I<LeftClick Shift-LeftClik> combination also
		487	selects words like the old code.
		488
		489	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		490
		491	You can disable the perl extension completely by setting the
		492	B<perl-ext-common> resource to the empty string, which also keeps
		493	rxvt-unicode from initialising perl, saving memory.
		494
		495	If you only want to disable specific features, you first have to
		496	identify which perl extension is responsible. For this, read the section
		497	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		498	example, to disable the B<selection-popup> and B<option-popup>, specify
		499	this B<perl-ext-common> resource:
		500
		501	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		502
		503	This will keep the default extensions, but disable the two popup
		504	extensions. Some extensions can also be configured, for example,
		505	scrollback search mode is triggered by B<M-s>. You can move it to any
		506	other combination either by setting the B<searchable-scrollback> resource:
		507
		508	URxvt.searchable-scrollback: CM-s
		509
		510	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		511
		512	See next entry.
		513
		514	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		515
		516	These are caused by the C<readline> perl extension. Under normal
		517	circumstances, it will move your cursor around when you click into the
		518	line that contains it. It tries hard not to do this at the wrong moment,
		519	but when running a program that doesn't parse cursor movements or in some
		520	cases during rlogin sessions, it fails to detect this properly.
		521
		522	You can permanently switch this feature off by disabling the C<readline>
		523	extension:
		524
		525	URxvt.perl-ext-common: default,-readline
		526
		527	=head3 My numerical keypad acts weird and generates differing output?
		528
		529	Some Debian GNUL/Linux users seem to have this problem, although no
		530	specific details were reported so far. It is possible that this is caused
		531	by the wrong C<TERM> setting, although the details of whether and how
		532	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		533	keymap. See the answer to the previous question, and please report if that
		534	helped.
		535
		536	=head3 My Compose (Multi_key) key is no longer working.
		537
		538	The most common causes for this are that either your locale is not set
		539	correctly, or you specified a B<preeditStyle> that is not supported by
		540	your input method. For example, if you specified B<OverTheSpot> and
		541	your input method (e.g. the default input method handling Compose keys)
		542	does not support this (for instance because it is not visual), then
		543	rxvt-unicode will continue without an input method.
		544
		545	In this case either do not specify a B<preeditStyle> or specify more than
		546	one pre-edit style, such as B<OverTheSpot,Root,None>.
		547
		548	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		549
		550	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		551	international keyboards) or simply use ISO 14755 support to your
		552	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		553	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		554	character and so on.
		555
		556	=head3 Mouse cut/paste suddenly no longer works.
		557
		558	Make sure that mouse reporting is actually turned off since killing
		559	some editors prematurely may leave the mouse in mouse report mode. I've
		560	heard that tcsh may use mouse reporting unless it otherwise specified. A
		561	quick check is to see if cut/paste works when the Alt or Shift keys are
		562	depressed.
		563
		564	=head3 What's with the strange Backspace/Delete key behaviour?
		565
		566	Assuming that the physical Backspace key corresponds to the
		567	Backspace keysym (not likely for Linux ... see the following
		568	question) there are two standard values that can be used for
		569	Backspace: C<^H> and C<^?>.
		570
		571	Historically, either value is correct, but rxvt-unicode adopts the debian
		572	policy of using C<^?> when unsure, because it's the one and only correct
		573	choice :).
		574
		575	Rxvt-unicode tries to inherit the current stty settings and uses the value
		576	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		577	started from a terminal (say, from a menu or by remote shell), then the
		578	system value of `erase', which corresponds to CERASE in <termios.h>, will
		579	be used (which may not be the same as your stty setting).
		580
		581	For starting a new rxvt-unicode:
		582
		583	# use Backspace = ^H
		584	$ stty erase ^H
		585	$ @@URXVT_NAME@@
		586
		587	# use Backspace = ^?
		588	$ stty erase ^?
		589	$ @@URXVT_NAME@@
		590
		591	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		592
		593	For an existing rxvt-unicode:
		594
		595	# use Backspace = ^H
		596	$ stty erase ^H
		597	$ echo -n "^[[36h"
		598
		599	# use Backspace = ^?
		600	$ stty erase ^?
		601	$ echo -n "^[[36l"
		602
		603	This helps satisfy some of the Backspace discrepancies that occur, but
		604	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		605	properly reflects that.
		606
		607	The Delete key is a another casualty of the ill-defined Backspace problem.
		608	To avoid confusion between the Backspace and Delete keys, the Delete
		609	key has been assigned an escape sequence to match the vt100 for Execute
		610	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		611
		612	Some other Backspace problems:
		613
		614	some editors use termcap/terminfo,
		615	some editors (vim I'm told) expect Backspace = ^H,
		616	GNU Emacs (and Emacs-like editors) use ^H for help.
		617
		618	Perhaps someday this will all be resolved in a consistent manner.
		619
		620	=head3 I don't like the key-bindings. How do I change them?
		621
		622	There are some compile-time selections available via configure. Unless
		623	you have run "configure" with the C<--disable-resources> option you can
		624	use the `keysym' resource to alter the keystrings associated with keysyms.
		625
		626	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
		627
		628	URxvt.keysym.Home: \033[1~
		629	URxvt.keysym.End: \033[4~

		648
		649	See some more examples in the documentation for the B<keysym> resource.
		650
		651	=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
		652
		653	KP_Insert == Insert
		654	F22 == Print
		655	F27 == Home
		656	F29 == Prior
		657	F33 == End
		658	F35 == Next
		659
		660	Rather than have rxvt-unicode try to accommodate all the various possible
		661	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		662	required for your particular machine.
		663
		664
		665	=head2 Terminal Configuration
		666
		667	=head3 Can I see a typical configuration?
		668
		669	The default configuration tries to be xterm-like, which I don't like that
		670	much, but it's least surprise to regular users.
		671
		672	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		673	time into customising your terminal. To get you started, here is the
		674	author's .Xdefaults entries, with comments on what they do. It's certainly
		675	not I<typical>, but what's typical...
		676
		677	URxvt.cutchars: "()*,<>[]{}|'
		678	URxvt.print-pipe: cat >/tmp/xxx
		679
		680	These are just for testing stuff.
		681
		682	URxvt.imLocale: ja_JP.UTF-8
		683	URxvt.preeditType: OnTheSpot,None
		684
		685	This tells rxvt-unicode to use a special locale when communicating with
		686	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		687	type, which requires the C<xim-onthespot> perl extension but rewards me
		688	with correct-looking fonts.
		689
		690	URxvt.perl-lib: /root/lib/urxvt
		691	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		692	URxvt.selection.pattern-0: ( at .*? line \\d+)
		693	URxvt.selection.pattern-1: ^(/[^:]+):\
		694	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		695	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		696
		697	This is my perl configuration. The first two set the perl library
		698	directory and also tells urxvt to use a large number of extensions. I
		699	develop for myself mostly, so I actually use most of the extensions I
		700	write.
		701
		702	The selection stuff mainly makes the selection perl-error-message aware
		703	and tells it to convert perl error messages into vi-commands to load the
		704	relevant file and go tot he error line number.
		705
		706	URxvt.scrollstyle: plain
		707	URxvt.secondaryScroll: true
		708
		709	As the documentation says: plain is the preferred scrollbar for the
		710	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		711	apps, like screen, so lines scrolled out of screen end up in urxvt's
		712	scrollback buffer.
		713
		714	URxvt.background: #000000
		715	URxvt.foreground: gray90
		716	URxvt.color7: gray90
		717	URxvt.colorBD: #ffffff
		718	URxvt.cursorColor: #e0e080
		719	URxvt.throughColor: #8080f0
		720	URxvt.highlightColor: #f0f0f0
		721
		722	Some colours. Not sure which ones are being used or even non-defaults, but
		723	these are in my .Xdefaults. Most notably, they set foreground/background
		724	to light gray/black, and also make sure that the colour 7 matches the
		725	default foreground colour.
		726
		727	URxvt.underlineColor: yellow
		728
		729	Another colour, makes underline lines look different. Sometimes hurts, but
		730	is mostly a nice effect.
		731
		732	URxvt.geometry: 154x36
		733	URxvt.loginShell: false
		734	URxvt.meta: ignore
		735	URxvt.utmpInhibit: true
		736
		737	Uh, well, should be mostly self-explanatory. By specifying some defaults
		738	manually, I can quickly switch them for testing.
		739
		740	URxvt.saveLines: 8192
		741
		742	A large scrollback buffer is essential. Really.
		743
		744	URxvt.mapAlert: true
		745
		746	The only case I use it is for my IRC window, which I like to keep
		747	iconified till people msg me (which beeps).
		748
		749	URxvt.visualBell: true
		750
		751	The audible bell is often annoying, especially when in a crowd.
		752

		769	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		770
		771	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		772	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		773	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		774	font (different glyphs for C<;> and many other harmless characters),
		775	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		776	bold version has less chars than the medium version, so I use it for rare
		777	characters, too. When editing sources with vim, I use italic for comments
		778	and other stuff, which looks quite good with Bitstream Vera anti-aliased.

		780	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		781	purposes, it works, and gives a different look, as my normal (Non-bold)
		782	font is already bold, and I want to see a difference between bold and
		783	normal fonts.
		784
		785	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		786	class name. Thats because I use different configs for different purposes,
		787	for example, my IRC window is started with C<-name IRC>, and uses these
		788	defaults:
		789
		790	IRC*title: IRC
		791	IRC*geometry: 87x12+535+542
		792	IRC*saveLines: 0

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

		822
		823	Well, why, indeed? It does, in a way very similar to other X
		824	applications. Most importantly, this means that if you or your OS loads
		825	resources into the X display (the right way to do it), rxvt-unicode will
		826	ignore any resource files in your home directory. It will only read
		827	F<$HOME/.Xdefaults> when no resources are attached to the display.
		828
		829	If you have or use an F<$HOME/.Xresources> file, chances are that
		830	resources are loaded into your X-server. In this case, you have to
		831	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		832
		833	Also consider the form resources have to use:
		834
		835	URxvt.resource: value
		836
		837	If you want to use another form (there are lots of different ways of
		838	specifying resources), make sure you understand whether and why it
		839	works. If unsure, use the form above.

385
386	=item Why do some chinese characters look so different than others?
387
388	This is because there is a difference between script and language --
389	rxvt-unicode does not know which language the text that is output is,
390	as it only knows the unicode character codes. If rxvt-unicode first
391	sees a japanese/chinese character, it might choose a japanese font for
392	display. Subsequent japanese characters will use that font. Now, many
393	chinese characters aren't represented in japanese fonts, so when the first
394	non-japanese character comes up, rxvt-unicode will look for a chinese font
395	-- unfortunately at this point, it will still use the japanese font for
396	chinese characters that are also in the japanese font.
397
398	The workaround is easy: just tag a chinese font at the end of your font
399	list (see the previous question). The key is to view the font list as
400	a preference list: If you expect more japanese, list a japanese font
401	first. If you expect more chinese, put a chinese font first.
402
403	In the future it might be possible to switch language preferences at
404	runtime (the internal data structure has no problem with using different
405	fonts for the same character at the same time, but no interface for this
406	has been designed yet).
407
408	Until then, you might get away with switching fonts at runtime (see L<Can
409	I switch the fonts at runtime?> later in this document).
410
411	=item Why does rxvt-unicode sometimes leave pixel droppings?
412
413	Most fonts were not designed for terminal use, which means that character
414	size varies a lot. A font that is otherwise fine for terminal use might
415	contain some characters that are simply too wide. Rxvt-unicode will avoid
416	these characters. For characters that are just "a bit" too wide a special
417	"careful" rendering mode is used that redraws adjacent characters.
418
419	All of this requires that fonts do not lie about character sizes,
420	however: Xft fonts often draw glyphs larger than their acclaimed bounding
421	box, and rxvt-unicode has no way of detecting this (the correct way is to

		1105	=head2 Operating Systems / Package Maintaining
		1106
		1107	=head3 I am using Debian GNU/Linux and have a problem...
		1108
		1109	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		1110	patches that considerably change the behaviour of rxvt-unicode (but
		1111	unfortunately this notice has been removed). Before reporting a bug to
		1112	the original rxvt-unicode author please download and install the genuine
		1113	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		1114	the problem. If you cannot, chances are that the problems are specific to
		1115	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		1116	Tracking System (use C<reportbug> to report the bug).
		1117
		1118	For other problems that also affect the Debian package, you can and
		1119	probably should use the Debian BTS, too, because, after all, it's also a
		1120	bug in the Debian version and it serves as a reminder for other users that
		1121	might encounter the same issue.
		1122
		1123	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1124
		1125	You should build one binary with the default options. F<configure>
		1126	now enables most useful options, and the trend goes to making them
		1127	runtime-switchable, too, so there is usually no drawback to enabling them,
		1128	except higher disk and possibly memory usage. The perl interpreter should
		1129	be enabled, as important functionality (menus, selection, likely more in
		1130	the future) depends on it.
		1131
		1132	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1133	system-wide (except maybe with C<defaults>). This will result in useful
		1134	behaviour. If your distribution aims at low memory, add an empty
		1135	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1136	perl interpreter disabled until the user enables it.
		1137
		1138	If you can/want build more binaries, I recommend building a minimal
		1139	one with C<--disable-everything> (very useful) and a maximal one with
		1140	C<--enable-everything> (less useful, it will be very big due to a lot of
		1141	encodings built-in that increase download times and are rarely used).
		1142
		1143	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1144
		1145	It should be, starting with release 7.1. You are encouraged to properly
		1146	install urxvt with privileges necessary for your OS now.
		1147
		1148	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1149	into a helper process for privileged operations (pty handling on some
		1150	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1151	immediately. This is much safer than most other terminals that keep
		1152	privileges while running (but is more relevant to urxvt, as it contains
		1153	things as perl interpreters, which might be "helpful" to attackers).
		1154
		1155	This forking is done as the very first within main(), which is very early
		1156	and reduces possible bugs to initialisation code run before main(), or
		1157	things like the dynamic loader of your system, which should result in very
		1158	little risk.

533		1206
534	=item Is there an option to switch encodings?	1207	urxvt uses the system wcwidth function to know the information about
		1208	the width of characters, so on systems with incorrect locale data you
		1209	will likely get bad results. Two notorious examples are Solaris 9,

538	UTF-8 or any other encodings with respect to terminal I/O.
539		1215
540	The reasons is that there exists a perfectly fine mechanism for selecting	1216	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
541	the encoding, doing I/O and (most important) communicating this to all
542	applications so everybody agrees on character properties such as width
543	and code number. This mechanism is the I<locale>. Applications not using
544	that info will have problems (for example, C<xterm> gets the width of
545	characters wrong as it uses it's own, locale-independent table under all
546	locales).
547		1217
548	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
549	programs doing the same (that is, most) will automatically agree in the
550	interpretation of characters.
551
552	Unfortunately, there is no system-independent way to select locales, nor
553	is there a standard on how locale specifiers will look like.
554
555	On most systems, the content of the C<LC_CTYPE> environment variable
556	contains an arbitrary string which corresponds to an already-installed
557	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
558	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
559	(i.e. C<de> or C<german>) are also common.
560
561	Rxvt-unicode ignores all other locale categories, and except for
562	the encoding, ignores country or language-specific settings,
563	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
564	rxvt-unicode.
565
566	If you want to use a specific encoding you have to make sure you start
567	rxvt-unicode with the correct C<LC_CTYPE> category.
568
569	=item Can I switch locales at runtime?
570
571	Yes, using an escape sequence. Try something like this, which sets
572	rxvt-unicode's idea of C<LC_CTYPE>.
573
574	printf '\e]701;%s\007' ja_JP.SJIS
575
576	See also the previous answer.
577
578	Sometimes this capability is rather handy when you want to work in
579	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
580	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
581	first switches to a locale supported by xjdic and back later:
582
583	printf '\e]701;%s\007' ja_JP.SJIS
584	xjdic -js
585	printf '\e]701;%s\007' de_DE.UTF-8
586
587	You can also use xterm's C<luit> program, which usually works fine, except
588	for some locales where character width differs between program- and
589	rxvt-unicode-locales.
590
591	=item Can I switch the fonts at runtime?
592
593	Yes, using an escape sequence. Try something like this, which has the same
594	effect as using the C<-fn> switch, and takes effect immediately:
595
596	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
597
598	This is useful if you e.g. work primarily with japanese (and prefer a
599	japanese font), but you have to switch to chinese temporarily, where
600	japanese fonts would only be in your way.
601
602	You can think of this as a kind of manual ISO-2022 switching.
603
604	=item Why do italic characters look as if clipped?
605
606	Many fonts have difficulties with italic characters and hinting. For
607	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
608	Mono> completely fails in it's italic face. A workaround might be to
609	enable freetype autohinting, i.e. like this:
610
611	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
612	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
613
614	=item My input method wants <some encoding> but I want UTF-8, what can I do?
615
616	You can specify separate locales for the input method and the rest of the
617	terminal, using the resource C<imlocale>:
618
619	URxvt.imlocale: ja_JP.EUC-JP
620
621	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
622	use your input method. Please note, however, that you will not be able to
623	input characters outside C<EUC-JP> in a normal way then, as your input
624	method limits you.
625
626	=item Rxvt-unicode crashes when the X Input Method changes or exits.
627
628	Unfortunately, this is unavoidable, as the XIM protocol is racy by
629	design. Applications can avoid some crashes at the expense of memory
630	leaks, and Input Methods can avoid some crashes by careful ordering at
631	exit time. B<kinput2> (and derived input methods) generally succeeds,
632	while B<SCIM> (or similar input methods) fails. In the end, however,
633	crashes cannot be completely avoided even if both sides cooperate.
634
635	So the only workaround is not to kill your Input Method Servers.
636
637	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
638
639	Rxvt-unicode tries to obey the rule of not charging you for something you
640	don't use. One thing you should try is to configure out all settings that
641	you don't need, for example, Xft support is a resource hog by design,
642	when used. Compiling it out ensures that no Xft font will be loaded
643	accidentally when rxvt-unicode tries to find a font for your characters.
644
645	Also, many people (me included) like large windows and even larger
646	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
647	6 bytes per screen cell. For a 160x?? window this amounts to almost a
648	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
649	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
650	rxvt-unicode then uses 8 bytes per screen cell.
651
652	=item Can I speed up Xft rendering somehow?
653
654	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
655	it is simply slow. If you still want Xft fonts you might try to disable
656	antialiasing (by appending C<:antialias=false>), which saves lots of
657	memory and also speeds up rendering considerably.
658
659	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
660
661	Rxvt-unicode will use whatever you specify as a font. If it needs to
662	fall back to it's default font search list it will prefer X11 core
663	fonts, because they are small and fast, and then use Xft fonts. It has
664	antialiasing disabled for most of them, because the author thinks they
665	look best that way.
666
667	If you want antialiasing, you have to specify the fonts manually.
668
669	=item Mouse cut/paste suddenly no longer works.
670
671	Make sure that mouse reporting is actually turned off since killing
672	some editors prematurely may leave the mouse in mouse report mode. I've
673	heard that tcsh may use mouse reporting unless it otherwise specified. A
674	quick check is to see if cut/paste works when the Alt or Shift keys are
675	depressed.
676
677	=item What's with this bold/blink stuff?
678
679	If no bold colour is set via C<colorBD:>, bold will invert text using the
680	standard foreground colour.
681
682	For the standard background colour, blinking will actually make the
683	text blink when compiled with C<--enable-blinking>. with standard
684	colours. Without C<--enable-blinking>, the blink attribute will be
685	ignored.
686
687	On ANSI colours, bold/blink attributes are used to set high-intensity
688	foreground/background colors.
689
690	color0-7 are the low-intensity colors.
691
692	color8-15 are the corresponding high-intensity colors.
693
694	=item I don't like the screen colors. How do I change them?

748
749	Assuming that the physical Backspace key corresponds to the
750	BackSpace keysym (not likely for Linux ... see the following
751	question) there are two standard values that can be used for
752	Backspace: C<^H> and C<^?>.
753
754	Historically, either value is correct, but rxvt-unicode adopts the debian
755	policy of using C<^?> when unsure, because it's the one only only correct
756	choice :).
757
758	Rxvt-unicode tries to inherit the current stty settings and uses the value
759	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
760	started from a terminal (say, from a menu or by remote shell), then the
761	system value of `erase', which corresponds to CERASE in <termios.h>, will
762	be used (which may not be the same as your stty setting).
763
764	For starting a new rxvt-unicode:
765
766	# use Backspace = ^H
767	$ stty erase ^H
768	$ @@RXVT_NAME@@
769
770	# use Backspace = ^?

772	$ @@RXVT_NAME@@
773
774	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
775
776	For an existing rxvt-unicode:

778	# use Backspace = ^H
779	$ stty erase ^H
780	$ echo -n "^[[36h"
781
782	# use Backspace = ^?
783	$ stty erase ^?
784	$ echo -n "^[[36l"
785
786	This helps satisfy some of the Backspace discrepancies that occur, but
787	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
788	properly reflects that.
789
790	The Delete key is a another casualty of the ill-defined Backspace problem.
791	To avoid confusion between the Backspace and Delete keys, the Delete
792	key has been assigned an escape sequence to match the vt100 for Execute
793	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
794
795	Some other Backspace problems:
796
797	some editors use termcap/terminfo,
798	some editors (vim I'm told) expect Backspace = ^H,
799	GNU Emacs (and Emacs-like editors) use ^H for help.
800
801	Perhaps someday this will all be resolved in a consistent manner.
802
803	=item I don't like the key-bindings. How do I change them?
804
805	There are some compile-time selections available via configure. Unless
806	you have run "configure" with the C<--disable-resources> option you can
807	use the `keysym' resource to alter the keystrings associated with keysyms.
808
809	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
810
811	URxvt.keysym.Home: \033[1~

834	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
835	How do I make use of them? For example, the Sun Keyboard type 4
836	has the following mappings that rxvt-unicode doesn't recognize.
837
838	KP_Insert == Insert
839	F22 == Print
840	F27 == Home
841	F29 == Prior
842	F33 == End
843	F35 == Next
844
845	Rather than have rxvt-unicode try to accommodate all the various possible
846	keyboard mappings, it is better to use `xmodmap' to remap the keys as
847	required for your particular machine.
848
849	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
850	I need this to decide about setting colors etc.
851
852	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
853	check and see if that is set. Note that several programs, JED, slrn,
854	Midnight Commander automatically check this variable to decide whether or
855	not to use color.
856
857	=item How do I set the correct, full IP address for the DISPLAY variable?
858
859	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
860	insecure mode then it is possible to use the following shell script
861	snippets to correctly set the display. If your version of rxvt-unicode
862	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
863	the COLORTERM variable can be used to distinguish rxvt-unicode from a
864	regular xterm.
865
866	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
867	snippets:
868
869	# Bourne/Korn/POSIX family of shells:
870	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
871	if [ ${TERM:-foo} = xterm ]; then
872	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
873	echo -n '^[Z'
874	read term_id
875	stty icanon echo
876	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
877	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
878	read DISPLAY # set it in our local shell
879	fi

881
882	=item How do I compile the manual pages for myself?
883
884	You need to have a recent version of perl installed as F</usr/bin/perl>,
885	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
886	the doc subdirectory and enter C<make alldoc>.

888	=item My question isn't answered here, can I ask a human?
889
890	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
891	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
892	interested in learning about new and exciting problems (but not FAQs :).
