		38	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
		39
		40	Beginning with version 7.3, there is a perl extension that implements a
		41	simple tabbed terminal. It is installed by default, so any of these should

		45
		46	URxvt.perl-ext-common: default,tabbed
		47
		48	It will also work fine with tabbing functionality of many window managers
		49	or similar tabbing programs, and its embedding-features allow it to be
		50	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		51	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		52	(murxvt) terminal as an example embedding application.

		73	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		74	rxvt-unicode then uses 8 bytes per screen cell.
48		75
		76	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
		77
		78	Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
		79	display, create the listening socket and then fork.
		80
		81	=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
		82
		83	If you want to start @@URXVT_NAME@@d automatically whenever you run
		84	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		85
		86	#!/bin/sh
		87	@@URXVT_NAME@@c "$@"
		88	if [ $? -eq 2 ]; then
		89	@@URXVT_NAME@@d -q -o -f
		90	@@URXVT_NAME@@c "$@"
		91	fi
		92
		93	This tries to create a new terminal, and if fails with exit status 2,
		94	meaning it couldn't connect to the daemon, it will start the daemon and
		95	re-run the command. Subsequent invocations of the script will re-use the
		96	existing daemon.
		97
		98	=head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
		99
		100	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		101	so you can check and see if that is set. Note that several programs, JED,
		102	slrn, Midnight Commander automatically check this variable to decide
		103	whether or not to use color.
		104
		105	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		106
		107	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		108	insecure mode then it is possible to use the following shell script
		109	snippets to correctly set the display. If your version of rxvt-unicode
		110	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		111	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		112	regular xterm.
		113
		114	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
		115	snippets:
		116
		117	# Bourne/Korn/POSIX family of shells:
		118	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
		119	if [ ${TERM:-foo} = xterm ]; then
		120	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
		121	echo -n '^[Z'
		122	read term_id
		123	stty icanon echo
		124	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
		125	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
		126	read DISPLAY # set it in our local shell
		127	fi
		128	fi
		129
		130	=head3 How do I compile the manual pages on my own?
		131
		132	You need to have a recent version of perl installed as F</usr/bin/perl>,
		133	one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
		134	F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.
		135
		136	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		137
		138	I often get asked about this, and I think, no, they didn't cause extra
		139	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		140	that the urxvt binary is larger (due to some encoding tables always being
		141	compiled in), but it actually uses less memory (RSS) after startup. Even
		142	with C<--disable-everything>, this comparison is a bit unfair, as many
		143	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		144	already in use in this mode.
		145
		146	text data bss drs rss filename
		147	98398 1664 24 15695 1824 rxvt --disable-everything
		148	188985 9048 66616 18222 1788 urxvt --disable-everything
		149
		150	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		151	and full locale/XIM support which are quite bloaty inside libX11 and my
		152	libc), the two diverge, but not unreasonably so.
		153
		154	text data bss drs rss filename
		155	163431 2152 24 20123 2060 rxvt --enable-everything
		156	1035683 49680 66648 29096 3680 urxvt --enable-everything
		157
		158	The very large size of the text section is explained by the east-asian
		159	encoding tables, which, if unused, take up disk space but nothing else
		160	and can be compiled out unless you rely on X11 core fonts that use those
		161	encodings. The BSS size comes from the 64k emergency buffer that my c++
		162	compiler allocates (but of course doesn't use unless you are out of
		163	memory). Also, using an xft font instead of a core font immediately adds a
		164	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		165	not used.
		166
		167	Of course, due to every character using two or four bytes instead of one,
		168	a large scrollback buffer will ultimately make rxvt-unicode use more
		169	memory.
		170
		171	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		172	still fares rather well. And compared to some monsters like gnome-terminal
		173	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		174	43180k in daemons that stay around after exit, plus half a minute of
		175	startup time, including the hundreds of warnings it spits out), it fares
		176	extremely well *g*.
		177
		178	=head3 Why C++, isn't that unportable/bloated/uncool?
		179
		180	Is this a question? :) It comes up very often. The simple answer is: I had
		181	to write it, and C++ allowed me to write and maintain it in a fraction
		182	of the time and effort (which is a scarce resource for me). Put even
		183	shorter: It simply wouldn't exist without C++.
		184
		185	My personal stance on this is that C++ is less portable than C, but in
		186	the case of rxvt-unicode this hardly matters, as its portability limits
		187	are defined by things like X11, pseudo terminals, locale support and unix
		188	domain sockets, which are all less portable than C++ itself.
		189
		190	Regarding the bloat, see the above question: It's easy to write programs
		191	in C that use gobs of memory, an certainly possible to write programs in
		192	C++ that don't. C++ also often comes with large libraries, but this is
		193	not necessarily the case with GCC. Here is what rxvt links against on my
		194	system with a minimal config:
		195
		196	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		197	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		198	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		199	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		200
		201	And here is rxvt-unicode:
		202
		203	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		204	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		205	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		206	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		207	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		208
		209	No large bloated libraries (of course, none were linked in statically),
		210	except maybe libX11 :)
		211
		212
		213	=head2 Rendering, Font & Look and Feel Issues
		214
		215	=head3 I can't get transparency working, what am I doing wrong?
		216
		217	First of all, please address all transparency related issues to Sasha Vasko at
		218	sasha@aftercode.net and do not bug the author about it. Also, if you can't
		219	get it working consider it a rite of passage: ... and you failed.
		220
		221	Here are four ways to get transparency. B<Do> read the manpage and option
		222	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		223
		224	1. Use transparent mode:
		225
		226	Esetroot wallpaper.jpg
		227	@@URXVT_NAME@@ -tr -tint red -sh 40
		228
		229	That works. If you think it doesn't, you lack transparency and tinting
		230	support, or you are unable to read.
		231
		232	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		233	to use effects other than tinting and shading: Just shade/tint/whatever
		234	your picture with gimp or any other tool:
		235
		236	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		237	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
		238
		239	That works. If you think it doesn't, you lack AfterImage support, or you
		240	are unable to read.
		241
		242	3. Use an ARGB visual:
		243
		244	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		245
		246	This requires XFT support, and the support of your X-server. If that
		247	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		248	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		249	bugfixes and workarounds for Xft and Xlib to make it work, but that
		250	doesn't mean that your WM has the required kludges in place.
		251
		252	4. Use xcompmgr and let it do the job:
		253
		254	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		255	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		256
		257	Then click on a window you want to make transparent. Replace C<0xc0000000>
		258	by other values to change the degree of opacity. If it doesn't work and
		259	your server crashes, you got to keep the pieces.
		260
		261	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		262
		263	Most fonts were not designed for terminal use, which means that character
		264	size varies a lot. A font that is otherwise fine for terminal use might
		265	contain some characters that are simply too wide. Rxvt-unicode will avoid
		266	these characters. For characters that are just "a bit" too wide a special
		267	"careful" rendering mode is used that redraws adjacent characters.
		268
		269	All of this requires that fonts do not lie about character sizes,
		270	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		271	box, and rxvt-unicode has no way of detecting this (the correct way is to
		272	ask for the character bounding box, which unfortunately is wrong in these
		273	cases).
		274
		275	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		276	or the respective font. If you encounter this problem you might try using
		277	the C<-lsp> option to give the font more height. If that doesn't work, you
		278	might be forced to use a different font.
		279
		280	All of this is not a problem when using X11 core fonts, as their bounding
		281	box data is correct.
		282
		283	=head3 How can I keep rxvt-unicode from using reverse video so much?
		284
		285	First of all, make sure you are running with the right terminal settings
		286	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		287	make sure you have specified colours for italic and bold, as otherwise
		288	rxvt-unicode might use reverse video to simulate the effect:
		289
		290	URxvt.colorBD: white
		291	URxvt.colorIT: green
		292
		293	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		294
		295	For some unexplainable reason, some rare programs assume a very weird
		296	colour palette when confronted with a terminal with more than the standard
		297	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		298	these programs not to assume non-ISO colours without very good reasons.
		299
		300	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		301	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		302	fix colours but keep you from using other rxvt-unicode features.
		303
		304	=head3 Can I switch the fonts at runtime?
		305
		306	Yes, using an escape sequence. Try something like this, which has the same
		307	effect as using the C<-fn> switch, and takes effect immediately:
		308
		309	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		310
		311	This is useful if you e.g. work primarily with japanese (and prefer a
		312	japanese font), but you have to switch to chinese temporarily, where
		313	japanese fonts would only be in your way.
		314
		315	You can think of this as a kind of manual ISO-2022 switching.
		316
		317	=head3 Why do italic characters look as if clipped?
		318
		319	Many fonts have difficulties with italic characters and hinting. For
		320	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		321	Mono> completely fails in its italic face. A workaround might be to
		322	enable freetype autohinting, i.e. like this:
		323
		324	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		325	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		326
		327	=head3 Can I speed up Xft rendering somehow?
		328
		329	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		330	it is simply slow. If you still want Xft fonts you might try to disable
		331	antialiasing (by appending C<:antialias=false>), which saves lots of
		332	memory and also speeds up rendering considerably.
		333
		334	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		335
		336	Rxvt-unicode will use whatever you specify as a font. If it needs to
		337	fall back to its default font search list it will prefer X11 core
		338	fonts, because they are small and fast, and then use Xft fonts. It has
		339	antialiasing disabled for most of them, because the author thinks they
		340	look best that way.
		341
		342	If you want antialiasing, you have to specify the fonts manually.
		343
		344	=head3 What's with this bold/blink stuff?
		345
		346	If no bold colour is set via C<colorBD:>, bold will invert text using the
		347	standard foreground colour.
		348
		349	For the standard background colour, blinking will actually make
		350	the text blink when compiled with C<--enable-text-blink>. Without
		351	C<--enable-text-blink>, the blink attribute will be ignored.
		352
		353	On ANSI colours, bold/blink attributes are used to set high-intensity
		354	foreground/background colors.
		355
		356	color0-7 are the low-intensity colors.
		357
		358	color8-15 are the corresponding high-intensity colors.
		359
		360	=head3 I don't like the screen colors. How do I change them?
		361
		362	You can change the screen colors at run-time using F<~/.Xdefaults>
		363	resources (or as long-options).
		364
		365	Here are values that are supposed to resemble a VGA screen,
		366	including the murky brown that passes for low-intensity yellow:
		367
		368	URxvt.color0: #000000
		369	URxvt.color1: #A80000
		370	URxvt.color2: #00A800
		371	URxvt.color3: #A8A800
		372	URxvt.color4: #0000A8
		373	URxvt.color5: #A800A8
		374	URxvt.color6: #00A8A8
		375	URxvt.color7: #A8A8A8
		376
		377	URxvt.color8: #000054
		378	URxvt.color9: #FF0054
		379	URxvt.color10: #00FF54
		380	URxvt.color11: #FFFF54
		381	URxvt.color12: #0000FF
		382	URxvt.color13: #FF00FF
		383	URxvt.color14: #00FFFF
		384	URxvt.color15: #FFFFFF
		385
		386	And here is a more complete set of non-standard colors.
		387
		388	URxvt.cursorColor: #dc74d1
		389	URxvt.pointerColor: #dc74d1
		390	URxvt.background: #0e0e0e
		391	URxvt.foreground: #4ad5e1
		392	URxvt.color0: #000000
		393	URxvt.color8: #8b8f93
		394	URxvt.color1: #dc74d1
		395	URxvt.color9: #dc74d1
		396	URxvt.color2: #0eb8c7
		397	URxvt.color10: #0eb8c7
		398	URxvt.color3: #dfe37e
		399	URxvt.color11: #dfe37e
		400	URxvt.color5: #9e88f0
		401	URxvt.color13: #9e88f0
		402	URxvt.color6: #73f7ff
		403	URxvt.color14: #73f7ff
		404	URxvt.color7: #e1dddd
		405	URxvt.color15: #e1dddd
		406
		407	They have been described (not by me) as "pretty girly".
		408
		409	=head3 Why do some characters look so much different than others?
		410
		411	See next entry.
		412
		413	=head3 How does rxvt-unicode choose fonts?
		414
		415	Most fonts do not contain the full range of Unicode, which is
		416	fine. Chances are that the font you (or the admin/package maintainer of
		417	your system/os) have specified does not cover all the characters you want
		418	to display.
		419
		420	B<rxvt-unicode> makes a best-effort try at finding a replacement
		421	font. Often the result is fine, but sometimes the chosen font looks
		422	bad/ugly/wrong. Some fonts have totally strange characters that don't
		423	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		424	intelligence to detect that a specific glyph is wrong: it has to believe
		425	the font that the characters it claims to contain indeed look correct.
		426
		427	In that case, select a font of your taste and add it to the font list,
		428	e.g.:
		429
		430	@@URXVT_NAME@@ -fn basefont,font2,font3...
		431
		432	When rxvt-unicode sees a character, it will first look at the base
		433	font. If the base font does not contain the character, it will go to the
		434	next font, and so on. Specifying your own fonts will also speed up this
		435	search and use less resources within rxvt-unicode and the X-server.
		436
		437	The only limitation is that none of the fonts may be larger than the base
		438	font, as the base font defines the terminal character cell size, which
		439	must be the same due to the way terminals work.
		440
		441	=head3 Why do some chinese characters look so different than others?
		442
		443	This is because there is a difference between script and language --
		444	rxvt-unicode does not know which language the text that is output is,
		445	as it only knows the unicode character codes. If rxvt-unicode first
		446	sees a japanese/chinese character, it might choose a japanese font for
		447	display. Subsequent japanese characters will use that font. Now, many
		448	chinese characters aren't represented in japanese fonts, so when the first
		449	non-japanese character comes up, rxvt-unicode will look for a chinese font
		450	-- unfortunately at this point, it will still use the japanese font for
		451	chinese characters that are also in the japanese font.
		452
		453	The workaround is easy: just tag a chinese font at the end of your font
		454	list (see the previous question). The key is to view the font list as
		455	a preference list: If you expect more japanese, list a japanese font
		456	first. If you expect more chinese, put a chinese font first.
		457
		458	In the future it might be possible to switch language preferences at
		459	runtime (the internal data structure has no problem with using different
		460	fonts for the same character at the same time, but no interface for this
		461	has been designed yet).
		462
		463	Until then, you might get away with switching fonts at runtime (see L<Can
		464	I switch the fonts at runtime?> later in this document).
		465
		466	=head3 How can I make mplayer display video correctly?
		467
		468	We are working on it, in the meantime, as a workaround, use something like:
		469
		470	@@URXVT_NAME@@ -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
		471
		472
		473	=head2 Keyboard, Mouse & User Interaction
		474
		475	=head3 The new selection selects pieces that are too big, how can I select single words?
		476
		477	If you want to select e.g. alphanumeric words, you can use the following
		478	setting:
		479
		480	URxvt.selection.pattern-0: ([[:word:]]+)
		481
		482	If you click more than twice, the selection will be extended
		483	more and more.
		484
		485	To get a selection that is very similar to the old code, try this pattern:
		486
		487	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		488
		489	Please also note that the I<LeftClick Shift-LeftClick> combination also
		490	selects words like the old code.
		491
		492	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		493
		494	You can disable the perl extension completely by setting the
		495	B<perl-ext-common> resource to the empty string, which also keeps
		496	rxvt-unicode from initialising perl, saving memory.
		497
		498	If you only want to disable specific features, you first have to
		499	identify which perl extension is responsible. For this, read the section
		500	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		501	example, to disable the B<selection-popup> and B<option-popup>, specify
		502	this B<perl-ext-common> resource:
		503
		504	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		505
		506	This will keep the default extensions, but disable the two popup
		507	extensions. Some extensions can also be configured, for example,
		508	scrollback search mode is triggered by B<M-s>. You can move it to any
		509	other combination either by setting the B<searchable-scrollback> resource:
		510
		511	URxvt.searchable-scrollback: CM-s
		512
		513	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		514
		515	See next entry.
		516
		517	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		518
		519	These are caused by the C<readline> perl extension. Under normal
		520	circumstances, it will move your cursor around when you click into the
		521	line that contains it. It tries hard not to do this at the wrong moment,
		522	but when running a program that doesn't parse cursor movements or in some
		523	cases during rlogin sessions, it fails to detect this properly.
		524
		525	You can permanently switch this feature off by disabling the C<readline>
		526	extension:
		527
		528	URxvt.perl-ext-common: default,-readline
		529
		530	=head3 My numerical keypad acts weird and generates differing output?
		531
		532	Some Debian GNUL/Linux users seem to have this problem, although no
		533	specific details were reported so far. It is possible that this is caused
		534	by the wrong C<TERM> setting, although the details of whether and how
		535	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		536	keymap. See the answer to the previous question, and please report if that
		537	helped.
		538
		539	=head3 My Compose (Multi_key) key is no longer working.
		540
		541	The most common causes for this are that either your locale is not set
		542	correctly, or you specified a B<preeditStyle> that is not supported by
		543	your input method. For example, if you specified B<OverTheSpot> and
		544	your input method (e.g. the default input method handling Compose keys)
		545	does not support this (for instance because it is not visual), then
		546	rxvt-unicode will continue without an input method.
		547
		548	In this case either do not specify a B<preeditStyle> or specify more than
		549	one pre-edit style, such as B<OverTheSpot,Root,None>.
		550
		551	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		552
		553	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		554	international keyboards) or simply use ISO 14755 support to your
		555	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		556	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		557	character and so on.
		558
		559	=head3 Mouse cut/paste suddenly no longer works.
		560
		561	Make sure that mouse reporting is actually turned off since killing
		562	some editors prematurely may leave the mouse in mouse report mode. I've
		563	heard that tcsh may use mouse reporting unless it otherwise specified. A
		564	quick check is to see if cut/paste works when the Alt or Shift keys are
		565	depressed.
		566
		567	=head3 What's with the strange Backspace/Delete key behaviour?
		568
		569	Assuming that the physical Backspace key corresponds to the
		570	Backspace keysym (not likely for Linux ... see the following
		571	question) there are two standard values that can be used for
		572	Backspace: C<^H> and C<^?>.
		573
		574	Historically, either value is correct, but rxvt-unicode adopts the debian
		575	policy of using C<^?> when unsure, because it's the one and only correct
		576	choice :).
		577
		578	Rxvt-unicode tries to inherit the current stty settings and uses the value
		579	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		580	started from a terminal (say, from a menu or by remote shell), then the
		581	system value of `erase', which corresponds to CERASE in <termios.h>, will
		582	be used (which may not be the same as your stty setting).
		583
		584	For starting a new rxvt-unicode:
		585
		586	# use Backspace = ^H
		587	$ stty erase ^H
		588	$ @@URXVT_NAME@@
		589
		590	# use Backspace = ^?
		591	$ stty erase ^?
		592	$ @@URXVT_NAME@@
		593
		594	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		595
		596	For an existing rxvt-unicode:
		597
		598	# use Backspace = ^H
		599	$ stty erase ^H
		600	$ echo -n "^[[36h"
		601
		602	# use Backspace = ^?
		603	$ stty erase ^?
		604	$ echo -n "^[[36l"
		605
		606	This helps satisfy some of the Backspace discrepancies that occur, but
		607	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		608	properly reflects that.
		609
		610	The Delete key is a another casualty of the ill-defined Backspace problem.
		611	To avoid confusion between the Backspace and Delete keys, the Delete
		612	key has been assigned an escape sequence to match the vt100 for Execute
		613	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		614
		615	Some other Backspace problems:
		616
		617	some editors use termcap/terminfo,
		618	some editors (vim I'm told) expect Backspace = ^H,
		619	GNU Emacs (and Emacs-like editors) use ^H for help.
		620
		621	Perhaps someday this will all be resolved in a consistent manner.
		622
		623	=head3 I don't like the key-bindings. How do I change them?
		624
		625	There are some compile-time selections available via configure. Unless
		626	you have run "configure" with the C<--disable-resources> option you can
		627	use the `keysym' resource to alter the keystrings associated with keysyms.
		628
		629	Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
		630
		631	URxvt.keysym.Home: \033[1~

		651
		652	See some more examples in the documentation for the B<keysym> resource.
		653
		654	=head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How do I make use of them? For example, the Sun Keyboard type 4 has the following map
		655
		656	KP_Insert == Insert
		657	F22 == Print
		658	F27 == Home
		659	F29 == Prior
		660	F33 == End
		661	F35 == Next
		662
		663	Rather than have rxvt-unicode try to accommodate all the various possible
		664	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		665	required for your particular machine.
		666
		667
		668	=head2 Terminal Configuration
		669
		670	=head3 Can I see a typical configuration?
		671
		672	The default configuration tries to be xterm-like, which I don't like that
		673	much, but it's least surprise to regular users.
		674
		675	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		676	time into customising your terminal. To get you started, here is the
		677	author's .Xdefaults entries, with comments on what they do. It's certainly
		678	not I<typical>, but what's typical...
		679
		680	URxvt.cutchars: "()*,<>[]{}|'
		681	URxvt.print-pipe: cat >/tmp/xxx
		682
		683	These are just for testing stuff.
		684
		685	URxvt.imLocale: ja_JP.UTF-8
		686	URxvt.preeditType: OnTheSpot,None
		687
		688	This tells rxvt-unicode to use a special locale when communicating with
		689	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		690	type, which requires the C<xim-onthespot> perl extension but rewards me
		691	with correct-looking fonts.
		692
		693	URxvt.perl-lib: /root/lib/urxvt
		694	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		695	URxvt.selection.pattern-0: ( at .*? line \\d+)
		696	URxvt.selection.pattern-1: ^(/[^:]+):\
		697	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		698	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		699
		700	This is my perl configuration. The first two set the perl library
		701	directory and also tells urxvt to use a large number of extensions. I
		702	develop for myself mostly, so I actually use most of the extensions I
		703	write.
		704
		705	The selection stuff mainly makes the selection perl-error-message aware
		706	and tells it to convert perl error messages into vi-commands to load the
		707	relevant file and go tot he error line number.
		708
		709	URxvt.scrollstyle: plain
		710	URxvt.secondaryScroll: true
		711
		712	As the documentation says: plain is the preferred scrollbar for the
		713	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		714	apps, like screen, so lines scrolled out of screen end up in urxvt's
		715	scrollback buffer.
		716
		717	URxvt.background: #000000
		718	URxvt.foreground: gray90
		719	URxvt.color7: gray90
		720	URxvt.colorBD: #ffffff
		721	URxvt.cursorColor: #e0e080
		722	URxvt.throughColor: #8080f0
		723	URxvt.highlightColor: #f0f0f0
		724
		725	Some colours. Not sure which ones are being used or even non-defaults, but
		726	these are in my .Xdefaults. Most notably, they set foreground/background
		727	to light gray/black, and also make sure that the colour 7 matches the
		728	default foreground colour.
		729
		730	URxvt.underlineColor: yellow
		731
		732	Another colour, makes underline lines look different. Sometimes hurts, but
		733	is mostly a nice effect.
		734
		735	URxvt.geometry: 154x36
		736	URxvt.loginShell: false
		737	URxvt.meta: ignore
		738	URxvt.utmpInhibit: true
		739
		740	Uh, well, should be mostly self-explanatory. By specifying some defaults
		741	manually, I can quickly switch them for testing.
		742
		743	URxvt.saveLines: 8192
		744
		745	A large scrollback buffer is essential. Really.
		746
		747	URxvt.mapAlert: true
		748
		749	The only case I use it is for my IRC window, which I like to keep
		750	iconified till people msg me (which beeps).
		751
		752	URxvt.visualBell: true
		753
		754	The audible bell is often annoying, especially when in a crowd.

		772	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		773
		774	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		775	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		776	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		777	font (different glyphs for C<;> and many other harmless characters),
		778	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		779	bold version has less chars than the medium version, so I use it for rare
		780	characters, too. When editing sources with vim, I use italic for comments
		781	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		782
		783	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		784	purposes, it works, and gives a different look, as my normal (Non-bold)
		785	font is already bold, and I want to see a difference between bold and
		786	normal fonts.
		787
		788	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		789	class name. Thats because I use different configs for different purposes,
		790	for example, my IRC window is started with C<-name IRC>, and uses these
		791	defaults:
		792
		793	IRC*title: IRC
		794	IRC*geometry: 87x12+535+542
		795	IRC*saveLines: 0
		796	IRC*mapAlert: true
		797	IRC*font: suxuseuro
		798	IRC*boldFont: suxuseuro
		799	IRC*colorBD: white
		800	IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
		801	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		802
		803	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		804	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		805	stuff while keeping a very small window. If somebody pastes something
		806	complicated (e.g. japanese), I temporarily switch to a larger font.
		807
		808	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		809	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		810	file for different hosts, for example, on ym main desktop, I use:
		811
		812	URxvt.keysym.C-M-q: command:\033[3;5;5t
		813	URxvt.keysym.C-M-y: command:\033[3;5;606t
		814	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		815	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		816	URxvt.keysym.C-M-p: perl:test
		817
		818	The first for keysym definitions allow me to quickly bring some windows
		819	in the layout I like most. Ion users might start laughing but will stop
		820	immediately when I tell them that I use my own Fvwm2 module for much the
		821	same effect as Ion provides, and I only very rarely use the above key
		822	combinations :->
		823
		824	=head3 Why doesn't rxvt-unicode read my resources?
		825
		826	Well, why, indeed? It does, in a way very similar to other X
		827	applications. Most importantly, this means that if you or your OS loads
		828	resources into the X display (the right way to do it), rxvt-unicode will
		829	ignore any resource files in your home directory. It will only read
		830	F<$HOME/.Xdefaults> when no resources are attached to the display.
		831
		832	If you have or use an F<$HOME/.Xresources> file, chances are that
		833	resources are loaded into your X-server. In this case, you have to
		834	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		835
		836	Also consider the form resources have to use:
		837
		838	URxvt.resource: value
		839
		840	If you want to use another form (there are lots of different ways of
		841	specifying resources), make sure you understand whether and why it
		842	works. If unsure, use the form above.

202	In that case, select a font of your taste and add it to the font list,	1002	The reasons is that there exists a perfectly fine mechanism for selecting

211
212	The only limitation is that none of the fonts may be larger than the base

215
216	=item Why do some chinese characters look so different than others?
217
218	This is because there is a difference between script and language --
219	rxvt-unicode does not know which language the text that is output is,
220	as it only knows the unicode character codes. If rxvt-unicode first
221	sees a japanese/chinese character, it might choose a japanese font for
222	display. Subsequent japanese characters will use that font. Now, many
223	chinese characters aren't represented in japanese fonts, so when the first
224	non-japanese character comes up, rxvt-unicode will look for a chinese font
225	-- unfortunately at this point, it will still use the japanese font for
226	chinese characters that are also in the japanese font.
227
228	The workaround is easy: just tag a chinese font at the end of your font
229	list (see the previous question). The key is to view the font list as
230	a preference list: If you expect more japanese, list a japanese font
231	first. If you expect more chinese, put a chinese font first.
232
233	In the future it might be possible to switch language preferences at
234	runtime (the internal data structure has no problem with using different
235	fonts for the same character at the same time, but no interface for this
236	has been designed yet).
237
238	Until then, you might get away with switching fonts at runtime (see L<Can
239	I switch the fonts at runtime?> later in this document).
240
241	=item Why does rxvt-unicode sometimes leave pixel droppings?
242
243	Most fonts were not designed for terminal use, which means that character
244	size varies a lot. A font that is otherwise fine for terminal use might
245	contain some characters that are simply too wide. Rxvt-unicode will avoid
246	these characters. For characters that are just "a bit" too wide a special
247	"careful" rendering mode is used that redraws adjacent characters.
248
249	All of this requires that fonts do not lie about character sizes,
250	however: Xft fonts often draw glyphs larger than their acclaimed bounding
251	box, and rxvt-unicode has no way of detecting this (the correct way is to
252	ask for the character bounding box, which unfortunately is wrong in these

		1117	the problem. If you cannot, chances are that the problems are specific to
		1118	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		1119	Tracking System (use C<reportbug> to report the bug).
		1120
		1121	For other problems that also affect the Debian package, you can and
		1122	probably should use the Debian BTS, too, because, after all, it's also a
		1123	bug in the Debian version and it serves as a reminder for other users that
		1124	might encounter the same issue.
		1125
		1126	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1127
		1128	You should build one binary with the default options. F<configure>
		1129	now enables most useful options, and the trend goes to making them
		1130	runtime-switchable, too, so there is usually no drawback to enabling them,
		1131	except higher disk and possibly memory usage. The perl interpreter should
		1132	be enabled, as important functionality (menus, selection, likely more in
		1133	the future) depends on it.
		1134
		1135	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1136	system-wide (except maybe with C<defaults>). This will result in useful
		1137	behaviour. If your distribution aims at low memory, add an empty
		1138	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1139	perl interpreter disabled until the user enables it.
		1140
		1141	If you can/want build more binaries, I recommend building a minimal
		1142	one with C<--disable-everything> (very useful) and a maximal one with
		1143	C<--enable-everything> (less useful, it will be very big due to a lot of
		1144	encodings built-in that increase download times and are rarely used).
		1145
		1146	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1147
		1148	It should be, starting with release 7.1. You are encouraged to properly
		1149	install urxvt with privileges necessary for your OS now.
		1150
		1151	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1152	into a helper process for privileged operations (pty handling on some
		1153	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1154	immediately. This is much safer than most other terminals that keep
		1155	privileges while running (but is more relevant to urxvt, as it contains
		1156	things as perl interpreters, which might be "helpful" to attackers).
		1157
		1158	This forking is done as the very first within main(), which is very early
		1159	and reduces possible bugs to initialisation code run before main(), or
		1160	things like the dynamic loader of your system, which should result in very
		1161	little risk.

353	the encoding, doing I/O and (most important) communicating this to all
354	applications so everybody agrees on character properties such as width
355	and code number. This mechanism is the I<locale>. Applications not using
356	that info will have problems (for example, C<xterm> gets the width of
357	characters wrong as it uses it's own, locale-independent table under all
358	locales).
359		1209
360	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All	1210	urxvt uses the system wcwidth function to know the information about

367	On most systems, the content of the C<LC_CTYPE> environment variable	1219	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
368	contains an arbitrary string which corresponds to an already-installed
369	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
370	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
371	(i.e. C<de> or C<german>) are also common.
372		1220
373	Rxvt-unicode ignores all other locale categories, and except for
374	the encoding, ignores country or language-specific settings,
375	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
376	rxvt-unicode.
377
378	If you want to use a specific encoding you have to make sure you start
379	rxvt-unicode with the correct C<LC_CTYPE> category.
380
381	=item Can I switch locales at runtime?
382
383	Yes, using an escape sequence. Try something like this, which sets
384	rxvt-unicode's idea of C<LC_CTYPE>.
385
386	printf '\e]701;%s\007' ja_JP.SJIS
387
388	See also the previous answer.
389
390	Sometimes this capability is rather handy when you want to work in
391	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
392	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
393	first switches to a locale supported by xjdic and back later:
394
395	printf '\e]701;%s\007' ja_JP.SJIS
396	xjdic -js
397	printf '\e]701;%s\007' de_DE.UTF-8
398
399	You can also use xterm's C<luit> program, which usually works fine, except
400	for some locales where character width differs between program- and
401	rxvt-unicode-locales.
402
403	=item Can I switch the fonts at runtime?
404
405	Yes, using an escape sequence. Try something like this, which has the same
406	effect as using the C<-fn> switch, and takes effect immediately:
407
408	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
409
410	This is useful if you e.g. work primarily with japanese (and prefer a
411	japanese font), but you have to switch to chinese temporarily, where
412	japanese fonts would only be in your way.
413
414	You can think of this as a kind of manual ISO-2022 switching.
415
416	=item Why do italic characters look as if clipped?
417
418	Many fonts have difficulties with italic characters and hinting. For
419	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
420	Mono> completely fails in it's italic face. A workaround might be to
421	enable freetype autohinting, i.e. like this:
422
423	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
424	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
425
426	=item My input method wants <some encoding> but I want UTF-8, what can I do?
427
428	You can specify separate locales for the input method and the rest of the
429	terminal, using the resource C<imlocale>:
430
431	URxvt*imlocale: ja_JP.EUC-JP
432
433	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
434	use your input method. Please note, however, that you will not be able to
435	input characters outside C<EUC-JP> in a normal way then, as your input
436	method limits you.
437
438	=item Rxvt-unicode crashes when the X Input Method changes or exits.
439
440	Unfortunately, this is unavoidable, as the XIM protocol is racy by
441	design. Applications can avoid some crashes at the expense of memory
442	leaks, and Input Methods can avoid some crashes by careful ordering at
443	exit time. B<kinput2> (and derived input methods) generally succeeds,
444	while B<SCIM> (or similar input methods) fails. In the end, however,
445	crashes cannot be completely avoided even if both sides cooperate.
446
447	So the only workaround is not to kill your Input Method Servers.
448
449	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
450
451	Rxvt-unicode tries to obey the rule of not charging you for something you
452	don't use. One thing you should try is to configure out all settings that
453	you don't need, for example, Xft support is a resource hog by design,
454	when used. Compiling it out ensures that no Xft font will be loaded
455	accidentally when rxvt-unicode tries to find a font for your characters.
456
457	Also, many people (me included) like large windows and even larger
458	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
459	6 bytes per screen cell. For a 160x?? window this amounts to almost a
460	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
461	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
462	rxvt-unicode then uses 8 bytes per screen cell.
463
464	=item Can I speed up Xft rendering somehow?
465
466	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
467	it is simply slow. If you still want Xft fonts you might try to disable
468	antialiasing (by appending C<:antialiasing=false>), which saves lots of
469	memory and also speeds up rendering considerably.
470
471	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
472
473	Rxvt-unicode will use whatever you specify as a font. If it needs to
474	fall back to it's default font search list it will prefer X11 core
475	fonts, because they are small and fast, and then use Xft fonts. It has
476	antialiasing disabled for most of them, because the author thinks they
477	look best that way.
478
479	If you want antialiasing, you have to specify the fonts manually.
480

488
489	=item What's with this bold/blink stuff?
490
491	If no bold colour is set via C<colorBD:>, bold will invert text using the
492	standard foreground colour.
493
494	For the standard background colour, blinking will actually make the
495	text blink when compiled with C<--enable-blinking>. with standard
496	colours. Without C<--enable-blinking>, the blink attribute will be
497	ignored.
498
499	On ANSI colours, bold/blink attributes are used to set high-intensity
500	foreground/background colors.
501
502	color0-7 are the low-intensity colors.
503
504	color8-15 are the corresponding high-intensity colors.

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 only 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	$ @@RXVT_NAME@@
587
588	# use Backspace = ^?

590	$ @@RXVT_NAME@@
591
592	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
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.

1515	B<< The exact syntax used is I<almost> solidified. >>
1516	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1517	menuBar.

1521
1522	=head2 Overview of menuBar operation
1523
1524	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1525	of C<Pt> can be used for a variety of tasks:
1526
1527	At the top level is the current menuBar which is a member of a circular
1528	linked-list of other such menuBars.
1529
1530	The menuBar acts as a parent for the various drop-down menus, which in
1531	turn, may have labels, separator lines, menuItems and subMenus.
1532
1533	The menuItems are the useful bits: you can use them to mimic keyboard
1534	input or even to send text or escape sequences back to rxvt.
1535
1536	The menuBar syntax is intended to provide a simple yet robust method of
1537	constructing and manipulating menus and navigating through the
1538	menuBars.
1539
1540	The first step is to use the tag B<< [menu:I<name>] >> which creates
1541	the menuBar called I<name> and allows access. You may now or menus,
1542	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1543	menuBar access as B<readonly> to prevent accidental corruption of the
1544	menus. To re-access the current menuBar for alterations, use the tag
1545	B<[menu]>, make the alterations and then use B<[done]>

1581	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1582
1583	Blank and comment lines (starting with B<#>) are ignored. Actually,
1584	since any invalid menu commands are also ignored, almost anything could
1585	be construed as a comment line, but this may be tightened up in the
1586	future ... so don't count on it!.
