		17
		18	This document contains the FAQ, the RXVT TECHNICAL REFERENCE documenting
		19	all escape sequences, and other background information.

		21	The newest version of this document is also available on the World Wide Web at
		22	L<http://cvs.schmorp.de/browse/rxvt-unicode/doc/rxvt.7.html>.
		23
		24	=head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
		25
		26
		27	=head2 Meta, Features & Commandline Issues
		28
		29	=head3 My question isn't answered here, can I ask a human?
		30
		31	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
		32	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
		33	interested in learning about new and exciting problems (but not FAQs :).
		34
		35	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
		36
		37	Beginning with version 7.3, there is a perl extension that implements a
		38	simple tabbed terminal. It is installed by default, so any of these should
		39	give you tabs:
		40
		41	@@URXVT_NAME@@ -pe tabbed
		42
		43	URxvt.perl-ext-common: default,tabbed
		44
		45	It will also work fine with tabbing functionality of many window managers
		46	or similar tabbing programs, and its embedding-features allow it to be
		47	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		48	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		49	(murxvt) terminal as an example embedding application.
		50
		51	=head3 How do I know which rxvt-unicode version I'm using?
		52
		53	The version number is displayed with the usage (-h). Also the escape
		54	sequence C<ESC [ 8 n> sets the window title to the version number. When
		55	using the @@URXVT_NAME@@c client, the version displayed is that of the
		56	daemon.
		57
		58	=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
		59
		60	Rxvt-unicode tries to obey the rule of not charging you for something you
		61	don't use. One thing you should try is to configure out all settings that
		62	you don't need, for example, Xft support is a resource hog by design,
		63	when used. Compiling it out ensures that no Xft font will be loaded
		64	accidentally when rxvt-unicode tries to find a font for your characters.
		65
		66	Also, many people (me included) like large windows and even larger
		67	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
		68	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		69	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		70	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		71	rxvt-unicode then uses 8 bytes per screen cell.
		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:
		113
		114	# Bourne/Korn/POSIX family of shells:
		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
		131	F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.
		132
		133	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		134
		135	I often get asked about this, and I think, no, they didn't cause extra
		136	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		137	that the urxvt binary is larger (due to some encoding tables always being
		138	compiled in), but it actually uses less memory (RSS) after startup. Even
		139	with C<--disable-everything>, this comparison is a bit unfair, as many
		140	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		141	already in use in this mode.
		142
		143	text data bss drs rss filename
		144	98398 1664 24 15695 1824 rxvt --disable-everything
		145	188985 9048 66616 18222 1788 urxvt --disable-everything
		146
		147	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		148	and full locale/XIM support which are quite bloaty inside libX11 and my
		149	libc), the two diverge, but not unreasonably so.
		150
		151	text data bss drs rss filename
		152	163431 2152 24 20123 2060 rxvt --enable-everything
		153	1035683 49680 66648 29096 3680 urxvt --enable-everything
		154
		155	The very large size of the text section is explained by the east-asian
		156	encoding tables, which, if unused, take up disk space but nothing else
		157	and can be compiled out unless you rely on X11 core fonts that use those
		158	encodings. The BSS size comes from the 64k emergency buffer that my c++
		159	compiler allocates (but of course doesn't use unless you are out of
		160	memory). Also, using an xft font instead of a core font immediately adds a
		161	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		162	not used.
		163
		164	Of course, due to every character using two or four bytes instead of one,
		165	a large scrollback buffer will ultimately make rxvt-unicode use more
		166	memory.
		167
		168	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		169	still fares rather well. And compared to some monsters like gnome-terminal
		170	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		171	43180k in daemons that stay around after exit, plus half a minute of
		172	startup time, including the hundreds of warnings it spits out), it fares
		173	extremely well *g*.
		174
		175	=head3 Why C++, isn't that unportable/bloated/uncool?
		176
		177	Is this a question? :) It comes up very often. The simple answer is: I had
		178	to write it, and C++ allowed me to write and maintain it in a fraction
		179	of the time and effort (which is a scarce resource for me). Put even
		180	shorter: It simply wouldn't exist without C++.
		181
		182	My personal stance on this is that C++ is less portable than C, but in
		183	the case of rxvt-unicode this hardly matters, as its portability limits
		184	are defined by things like X11, pseudo terminals, locale support and unix
		185	domain sockets, which are all less portable than C++ itself.
		186
		187	Regarding the bloat, see the above question: It's easy to write programs
		188	in C that use gobs of memory, an certainly possible to write programs in
		189	C++ that don't. C++ also often comes with large libraries, but this is
		190	not necessarily the case with GCC. Here is what rxvt links against on my
		191	system with a minimal config:
		192
		193	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		194	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		195	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		196	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		197
		198	And here is rxvt-unicode:
		199
		200	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		201	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		202	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		203	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		204	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		205
		206	No large bloated libraries (of course, none were linked in statically),
		207	except maybe libX11 :)
		208
		209
		210	=head2 Rendering, Font & Look and Feel Issues
		211
		212	=head3 I can't get transparency working, what am I doing wrong?
		213
		214	First of all, please address all transparency related issues to Sasha Vasko at
		215	sasha@aftercode.net and do not bug the author about it. Also, if you can't
		216	get it working consider it a rite of passage: ... and you failed.
		217
		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!
		220
		221	1. Use transparent mode:
		222
		223	Esetroot wallpaper.jpg
		224	@@URXVT_NAME@@ -tr -tint red -sh 40
		225
		226	That works. If you think it doesn't, you lack transparency and tinting
		227	support, or you are unable to read.
		228
		229	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		230	to use effects other than tinting and shading: Just shade/tint/whatever
		231	your picture with gimp or any other tool:
		232
		233	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		234	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
		235
		236	That works. If you think it doesn't, you lack AfterImage support, or you
		237	are unable to read.
		238
		239	3. Use an ARGB visual:
		240
		241	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		242
		243	This requires XFT support, and the support of your X-server. If that
		244	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		245	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		246	bugfixes and workarounds for Xft and Xlib to make it work, but that
		247	doesn't mean that your WM has the required kludges in place.
		248
		249	4. Use xcompmgr and let it do the job:
		250
		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~

		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
		753	URxvt.insecure: true
		754
		755	Please don't hack my mutt! Ooops...
		756
		757	URxvt.pastableTabs: false
		758
		759	I once thought this is a great idea.
		760

		762	-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
		763	-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
		764	[codeset=JISX0208]xft:Kochi Gothic, \

		768	urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		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.
		779
		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
		793	IRC*mapAlert: true
		794	IRC*font: suxuseuro
		795	IRC*boldFont: suxuseuro
		796	IRC*colorBD: white
		797	IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
		798	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		799
		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:
		808
		809	URxvt.keysym.C-M-q: command:\033[3;5;5t
		810	URxvt.keysym.C-M-y: command:\033[3;5;606t
		811	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		812	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		813	URxvt.keysym.C-M-p: perl:test
		814
		815	The first for keysym definitions allow me to quickly bring some windows
		816	in the layout I like most. Ion users might start laughing but will stop
		817	immediately when I tell them that I use my own Fvwm2 module for much the
		818	same effect as Ion provides, and I only very rarely use the above key
		819	combinations :->
		820
		821	=head3 Why doesn't rxvt-unicode read my resources?
		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.
		840
		841	=head3 When I log-in to another system it tells me about missing terminfo data?
		842
		843	The terminal description used by rxvt-unicode is not as widely available
		844	as that for xterm, or even rxvt (for which the same problem often arises).
		845
		846	The correct solution for this problem is to install the terminfo, this can
		847	be done like this (with ncurses' infocmp and works as user and admin):
		848
		849	REMOTE=remotesystem.domain
		850	infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
		851
		852	... or by installing rxvt-unicode normally on the remote system,
		853
		854	One some systems you might need to set C<$TERMINFO> to the full path of
		855	F<$HOME/.terminfo> for this to work.
		856
		857	If you cannot or do not want to do this, then you can simply set
		858	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		859	problems arising, which includes wrong keymapping, less and different
		860	colours and some refresh errors in fullscreen applications. It's a nice
		861	quick-and-dirty workaround for rare cases, though.
		862
		863	If you always want to do this (and are fine with the consequences) you
		864	can either recompile rxvt-unicode with the desired TERM value or use a
		865	resource to set it:
		866
		867	URxvt.termName: rxvt
		868
		869	If you don't plan to use B<rxvt> (quite common...) you could also replace
		870	the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
		871
		872	=head3 C<tic> outputs some error when compiling the terminfo entry.
		873
		874	Most likely it's the empty definition for C<enacs=>. Just replace it by
		875	C<enacs=\E[0@> and try again.
		876
		877	=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
		878
		879	See next entry.
		880
		881	=head3 I need a termcap file entry.
		882
		883	One reason you might want this is that some distributions or operating
		884	systems still compile some programs using the long-obsoleted termcap
		885	library (Fedora Core's bash is one example) and rely on a termcap entry
		886	for C<rxvt-unicode>.
		887
		888	You could use rxvt's termcap entry with reasonable results in many cases.
		889	You can also create a termcap entry by using terminfo's infocmp program
		890	like this:
		891
		892	infocmp -C rxvt-unicode
		893
		894	Or you could use this termcap entry, generated by the command above:

		917	=head3 Why does C<ls> no longer have coloured output?
		918
		919	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		920	decide whether a terminal has colour, but uses its own configuration
		921	file. Needless to say, C<rxvt-unicode> is not in its default file (among
		922	with most other terminals supporting colour). Either add:
		923
		924	TERM rxvt-unicode
		925
		926	to C</etc/DIR_COLORS> or simply add:
		927
		928	alias ls='ls --color=auto'
		929
		930	to your C<.profile> or C<.bashrc>.
		931
		932	=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
		933
		934	See next entry.
		935
		936	=head3 Why doesn't vim/emacs etc. make use of italic?
		937
		938	See next entry.
		939
		940	=head3 Why are the secondary screen-related options not working properly?
		941
		942	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		943	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		944	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		945	features. Unfortunately, some of these (most notably, again, Debian
		946	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		947	file, so you will need to install it on your own (See the question B<When
		948	I log-in to another system it tells me about missing terminfo data?> on
		949	how to do this).
		950
		951
		952	=head2 Encoding / Locale / Input Method Issues
		953
		954	=head3 Rxvt-unicode does not seem to understand the selected encoding?
		955
		956	See next entry.
		957
		958	=head3 Unicode does not seem to work?
		959
		960	If you encounter strange problems like typing an accented character but
		961	getting two unrelated other characters or similar, or if program output is
		962	subtly garbled, then you should check your locale settings.
		963
		964	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		965	programs running in it. Often rxvt-unicode is started in the C<C> locale,
		966	while the login script running within the rxvt-unicode window changes the
		967	locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
		968	not going to work, and is the most common cause for problems.
		969
		970	The best thing is to fix your startup environment, as you will likely run
		971	into other problems. If nothing works you can try this in your .profile.
		972
		973	printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
		974
		975	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		976	supported on your systems. Some systems have a C<locale> command which
		977	displays this (also, C<perl -e0> can be used to check locale settings, as
		978	it will complain loudly if it cannot set the locale). If it displays something
		979	like:
		980
		981	locale: Cannot set LC_CTYPE to default locale: ...
		982
		983	Then the locale you specified is not supported on your system.
		984
		985	If nothing works and you are sure that everything is set correctly then
		986	you will need to remember a little known fact: Some programs just don't
		987	support locales :(
		988
		989	=head3 How does rxvt-unicode determine the encoding to use?
		990
		991	See next entry.
		992
		993	=head3 Is there an option to switch encodings?
		994
		995	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		996	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		997	UTF-8 or any other encodings with respect to terminal I/O.
		998
		999	The reasons is that there exists a perfectly fine mechanism for selecting
		1000	the encoding, doing I/O and (most important) communicating this to all
		1001	applications so everybody agrees on character properties such as width
		1002	and code number. This mechanism is the I<locale>. Applications not using
		1003	that info will have problems (for example, C<xterm> gets the width of
		1004	characters wrong as it uses its own, locale-independent table under all
		1005	locales).
		1006
		1007	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		1008	programs doing the same (that is, most) will automatically agree in the
		1009	interpretation of characters.
		1010
		1011	Unfortunately, there is no system-independent way to select locales, nor
		1012	is there a standard on how locale specifiers will look like.
		1013
		1014	On most systems, the content of the C<LC_CTYPE> environment variable
		1015	contains an arbitrary string which corresponds to an already-installed
		1016	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		1017	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		1018	(i.e. C<de> or C<german>) are also common.
		1019
		1020	Rxvt-unicode ignores all other locale categories, and except for
		1021	the encoding, ignores country or language-specific settings,
		1022	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		1023	rxvt-unicode.
		1024
		1025	If you want to use a specific encoding you have to make sure you start
		1026	rxvt-unicode with the correct C<LC_CTYPE> category.
		1027
		1028	=head3 Can I switch locales at runtime?
		1029
		1030	Yes, using an escape sequence. Try something like this, which sets
		1031	rxvt-unicode's idea of C<LC_CTYPE>.
		1032
		1033	printf '\33]701;%s\007' ja_JP.SJIS
		1034
		1035	See also the previous answer.
		1036
		1037	Sometimes this capability is rather handy when you want to work in
		1038	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		1039	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		1040	first switches to a locale supported by xjdic and back later:
		1041
		1042	printf '\33]701;%s\007' ja_JP.SJIS
		1043	xjdic -js
		1044	printf '\33]701;%s\007' de_DE.UTF-8
		1045
		1046	You can also use xterm's C<luit> program, which usually works fine, except
		1047	for some locales where character width differs between program- and
		1048	rxvt-unicode-locales.
		1049
		1050	=head3 I have problems getting my input method working.
		1051
		1052	Try a search engine, as this is slightly different for every input method server.
		1053
		1054	Here is a checklist:
		1055
		1056	=over 4
		1057
		1058	=item - Make sure your locale I<and> the imLocale are supported on your OS.
		1059
		1060	Try C<locale -a> or check the documentation for your OS.
		1061
		1062	=item - Make sure your locale or imLocale matches a locale supported by your XIM.
		1063
		1064	For example, B<kinput2> does not support UTF-8 locales, you should use
		1065	C<ja_JP.EUC-JP> or equivalent.
		1066
		1067	=item - Make sure your XIM server is actually running.
		1068
		1069	=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
		1070
		1071	When you want to use e.g. B<kinput2>, it must be set to
		1072	C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
		1073	method servers are running with this command:
		1074
		1075	xprop -root XIM_SERVERS
		1076
		1077	=item
		1078
		1079	=back
		1080
		1081	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		1082
		1083	You can specify separate locales for the input method and the rest of the
		1084	terminal, using the resource C<imlocale>:
		1085
		1086	URxvt.imlocale: ja_JP.EUC-JP
		1087
		1088	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		1089	use your input method. Please note, however, that, depending on your Xlib
		1090	version, you may not be able to input characters outside C<EUC-JP> in a
		1091	normal way then, as your input method limits you.
		1092
		1093	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		1094
		1095	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		1096	design. Applications can avoid some crashes at the expense of memory
		1097	leaks, and Input Methods can avoid some crashes by careful ordering at
		1098	exit time. B<kinput2> (and derived input methods) generally succeeds,
		1099	while B<SCIM> (or similar input methods) fails. In the end, however,
		1100	crashes cannot be completely avoided even if both sides cooperate.
		1101
		1102	So the only workaround is not to kill your Input Method Servers.
		1103
		1104
		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.
		1159
		1160	=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
		1161
		1162	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		1163	in your compile environment, or an implementation that implements it,
		1164	whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		1165	B<wchar_t> is represented as unicode.
		1166
		1167	As you might have guessed, FreeBSD does neither define this symbol nor
		1168	does it support it. Instead, it uses its own internal representation of
		1169	B<wchar_t>. This is, of course, completely fine with respect to standards.
		1170
		1171	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		1172	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		1173
		1174	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		1175	apps in an OS, as using a locale-dependent (and non-standardized)
		1176	representation of B<wchar_t> makes it impossible to convert between
		1177	B<wchar_t> (as used by X11 and your applications) and any other encoding
		1178	without implementing OS-specific-wrappers for each and every locale. There
		1179	simply are no APIs to convert B<wchar_t> into anything except the current
		1180	locale encoding.
		1181
		1182	Some applications (such as the formidable B<mlterm>) work around this
		1183	by carrying their own replacement functions for character set handling
		1184	with them, and either implementing OS-dependent hacks or doing multiple
		1185	conversions (which is slow and unreliable in case the OS implements
		1186	encodings slightly different than the terminal emulator).
		1187
		1188	The rxvt-unicode author insists that the right way to fix this is in the
		1189	system libraries once and for all, instead of forcing every app to carry
		1190	complete replacements for them :)
		1191
		1192	=head3 How can I use rxvt-unicode under cygwin?
		1193
		1194	rxvt-unicode should compile and run out of the box on cygwin, using
		1195	the X11 libraries that come with cygwin. libW11 emulation is no
		1196	longer supported (and makes no sense, either, as it only supported a
		1197	single font). I recommend starting the X-server in C<-multiwindow> or
		1198	C<-rootless> mode instead, which will result in similar look&feel as the
		1199	old libW11 emulation.
		1200
		1201	At the time of this writing, cygwin didn't seem to support any multi-byte
		1202	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		1203	to 8-bit encodings.
		1204
		1205	=head3 Character widths are not correct.
		1206
		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,
		1210	where single-width characters like U+2514 are reported as double-width,
		1211	and Darwin 8, where combining chars are reported having width 1.
		1212
		1213	The solution is to upgrade your system or switch to a better one. A
		1214	possibly working workaround is to use a wcwidth implementation like
		1215
		1216	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

741
742	B<< The exact syntax used is I<almost> solidified. >>
743	In the menus, B<DON'T> try to use menuBar commands that add or remove a
744	menuBar.
745
746	Note that in all of the commands, the B<< I</path/> >> I<cannot> be

748
749	=head2 Overview of menuBar operation
750
751	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
752	of C<Pt> can be used for a variety of tasks:
753
754	At the top level is the current menuBar which is a member of a circular
755	linked-list of other such menuBars.
756
757	The menuBar acts as a parent for the various drop-down menus, which in
758	turn, may have labels, separator lines, menuItems and subMenus.
759
760	The menuItems are the useful bits: you can use them to mimic keyboard
761	input or even to send text or escape sequences back to rxvt.
762
763	The menuBar syntax is intended to provide a simple yet robust method of
764	constructing and manipulating menus and navigating through the
765	menuBars.
766
767	The first step is to use the tag B<< [menu:I<name>] >> which creates
768	the menuBar called I<name> and allows access. You may now or menus,
769	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
770	menuBar access as B<readonly> to prevent accidental corruption of the
771	menus. To re-access the current menuBar for alterations, use the tag
772	B<[menu]>, make the alterations and then use B<[done]>

784	menuBar is pushed onto the stack

806	appended if required.) Start reading at a line with B<[menu]> or B<<
807	[menu:+I<name> >> and continuing until B<[done]> is encountered.
808
809	Blank and comment lines (starting with B<#>) are ignored. Actually,
810	since any invalid menu commands are also ignored, almost anything could
811	be construed as a comment line, but this may be tightened up in the
812	future ... so don't count on it!.
813

1028	The menus also provide a hook for I<quick arrows> to provide easier
1029	user access. If nothing has been explicitly set, the default is to
1030	emulate the curror keys. The syntax permits each arrow to be altered
1031	individually or all four at once without re-entering their common
1032	beginning/end text. For example, to explicitly associate cursor actions
1033	with the arrows, any of the following forms could be used:
1034
1035	=over 4
1036
1037	=item B<< <r>+I<Right> >>
1038
1039	=item B<< <l>+I<Left> >>

1041	=item B<< <u>+I<Up> >>

1047	=item B<< <b>+I<Begin> >>
1048
1049	=item B<< <e>+I<End> >>

		2224	=head1 CONFIGURE OPTIONS
		2225
		2226	General hint: if you get compile errors, then likely your configuration
		2227	hasn't been tested well. Either try with C<--enable-everything> or use
		2228	the default configuration (i.e. no C<--enable-xxx> or C<--disable-xxx>
		2229	switches). Of course, you should always report when a combination doesn't
		2230	work, so it can be fixed. Marc Lehmann <rxvt@schmorp.de>.
		2231
		2232	All
		2233
		2234	=over 4
		2235
		2236	=item --enable-everything
		2237
		2238	Add (or remove) support for all non-multichoice options listed in "./configure
		2239	--help".
		2240
		2241	You can specify this and then disable options you do not like by
		2242	I<following> this with the appropriate C<--disable-...> arguments,
		2243	or you can start with a minimal configuration by specifying
		2244	C<--disable-everything> and than adding just the C<--enable-...> arguments
		2245	you want.
		2246
		2247	=item --enable-xft (default: enabled)
		2248
		2249	Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
		2250	slower and require lots of memory, but as long as you don't use them, you
		2251	don't pay for them.
		2252
		2253	=item --enable-font-styles (default: on)
		2254
		2255	Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
		2256	styles. The fonts can be set manually or automatically.
		2257
		2258	=item --with-codesets=NAME,... (default: all)
		2259
		2260	Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
		2261	are always compiled in, which includes most 8-bit character sets). These
		2262	codeset tables are used for driving X11 core fonts, they are not required
		2263	for Xft fonts, although having them compiled in lets rxvt-unicode choose
		2264	replacement fonts more intelligently. Compiling them in will make your
		2265	binary bigger (all of together cost about 700kB), but it doesn't increase
		2266	memory usage unless you use a font requiring one of these encodings.
		2267
		2268	=begin table
		2269
		2270	all all available codeset groups
		2271	zh common chinese encodings
		2272	zh_ext rarely used but very big chinese encodings

		2274	jp_ext rarely used but big japanese encodings
		2275	kr korean encodings
		2276
		2277	=end table
		2278
		2279	=item --enable-xim (default: on)
		2280
		2281	Add support for XIM (X Input Method) protocol. This allows using
		2282	alternative input methods (e.g. kinput2) and will also correctly
		2283	set up the input for people using dead keys or compose keys.
		2284
		2285	=item --enable-unicode3 (default: off)
		2286
		2287	Recommended to stay off unless you really need non-BMP characters.
		2288
		2289	Enable direct support for displaying unicode codepoints above
		2290	65535 (the basic multilingual page). This increases storage
		2291	requirements per character from 2 to 4 bytes. X11 fonts do not yet
		2292	support these extra characters, but Xft does.
		2293
		2294	Please note that rxvt-unicode can store unicode code points >65535
		2295	even without this flag, but the number of such characters is
		2296	limited to a few thousand (shared with combining characters,
		2297	see next switch), and right now rxvt-unicode cannot display them
		2298	(input/output and cut&paste still work, though).
		2299
		2300	=item --enable-combining (default: on)
		2301
		2302	Enable automatic composition of combining characters into
		2303	composite characters. This is required for proper viewing of text
		2304	where accents are encoded as seperate unicode characters. This is
		2305	done by using precomposited characters when available or creating
		2306	new pseudo-characters when no precomposed form exists.
		2307
		2308	Without --enable-unicode3, the number of additional precomposed
		2309	characters is somewhat limited (the 6400 private use characters will be
		2310	(ab-)used). With --enable-unicode3, no practical limit exists.
		2311
		2312	This option will also enable storage (but not display) of characters
		2313	beyond plane 0 (>65535) when --enable-unicode3 was not specified.
		2314
		2315	The combining table also contains entries for arabic presentation forms,
		2316	but these are not currently used. Bug me if you want these to be used (and
		2317	tell me how these are to be used...).
		2318
		2319	=item --enable-fallback(=CLASS) (default: Rxvt)
		2320
		2321	When reading resource settings, also read settings for class CLASS. To
		2322	disable resource fallback use --disable-fallback.
		2323
		2324	=item --with-res-name=NAME (default: urxvt)
		2325
		2326	Use the given name as default application name when
		2327	reading resources. Specify --with-res-name=rxvt to replace rxvt.
		2328
		2329	=item --with-res-class=CLASS /default: URxvt)
		2330
		2331	Use the given class as default application class
		2332	when reading resources. Specify --with-res-class=Rxvt to replace
		2333	rxvt.
		2334
		2335	=item --enable-utmp (default: on)
		2336
		2337	Write user and tty to utmp file (used by programs like F<w>) at
		2338	start of rxvt execution and delete information when rxvt exits.
		2339
		2340	=item --enable-wtmp (default: on)
		2341
		2342	Write user and tty to wtmp file (used by programs like F<last>) at
		2343	start of rxvt execution and write logout when rxvt exits. This
		2344	option requires --enable-utmp to also be specified.
		2345
		2346	=item --enable-lastlog (default: on)
		2347
		2348	Write user and tty to lastlog file (used by programs like
		2349	F<lastlogin>) at start of rxvt execution. This option requires
		2350	--enable-utmp to also be specified.
		2351
		2352	=item --enable-afterimage (default: on)
		2353
		2354	Add support for libAfterImage to be used for transparency and background
		2355	images. It adds support for many file formats including JPG, PNG,
		2356	SVG, TIFF, GIF, XPM, BMP, ICO, XCF, TGA and AfterStep image XML
		2357	(L<http://www.afterstep.org/visualdoc.php?show=asimagexml>).
		2358
		2359	This option also adds such eye candy as blending an image over the root
		2360	background, as well as dynamic scaling and bluring of background images.
		2361
		2362	Note that with this option enabled, @@RXVT_NAME@@'s memory footprint might
		2363	increase by a few megabytes even if no extra features are used (mostly due
		2364	to third-party libraries used by libAI). Memory footprint may somewhat be
		2365	lowered if libAfterImage is configured without support for SVG.
		2366
		2367	=item --enable-transparency (default: on)
		2368
		2369	Add support for backgrounds, creating illusion of transparency in the term.
		2370
		2371	=item --enable-fading (default: on)
		2372
		2373	Add support for fading the text when focus is lost.
		2374
		2375	=item --enable-rxvt-scroll (default: on)
		2376
		2377	Add support for the original rxvt scrollbar.
		2378
		2379	=item --enable-next-scroll (default: on)
		2380
		2381	Add support for a NeXT-like scrollbar.
		2382
		2383	=item --enable-xterm-scroll (default: on)
		2384
		2385	Add support for an Xterm-like scrollbar.
		2386
		2387	=item --enable-plain-scroll (default: on)
		2388
		2389	Add support for a very unobtrusive, plain-looking scrollbar that
		2390	is the favourite of the rxvt-unicode author, having used it for
		2391	many years.
		2392
		2393	=item --enable-ttygid (default: off)
		2394
		2395	Change tty device setting to group "tty" - only use this if
		2396	your system uses this type of security.
		2397
		2398	=item --disable-backspace-key
		2399
		2400	Removes any handling of the backspace key by us - let the X server do it.
		2401
		2402	=item --disable-delete-key
		2403
		2404	Removes any handling of the delete key by us - let the X server
		2405	do it.
		2406
		2407	=item --disable-resources
		2408
		2409	Removes any support for resource checking.
		2410
		2411	=item --disable-swapscreen
		2412
		2413	Remove support for secondary/swap screen.
		2414
		2415	=item --enable-frills (default: on)
		2416
		2417	Add support for many small features that are not essential but nice to
		2418	have. Normally you want this, but for very small binaries you may want to
		2419	disable this.
		2420
		2421	A non-exhaustive list of features enabled by C<--enable-frills> (possibly
		2422	in combination with other switches) is:
		2423
		2424	MWM-hints
		2425	EWMH-hints (pid, utf8 names) and protocols (ping)
		2426	urgency hint
		2427	seperate underline colour (-underlineColor)
		2428	settable border widths and borderless switch (-w, -b, -bl)
		2429	visual depth selection (-depth)
		2430	settable extra linespacing /-lsp)
		2431	iso-14755 5.1 (basic) support
		2432	tripleclickwords (-tcw)
		2433	settable insecure mode (-insecure)
		2434	keysym remapping support
		2435	cursor blinking and underline cursor (-cb, -uc)
		2436	XEmbed support (-embed)
		2437	user-pty (-pty-fd)
		2438	hold on exit (-hold)
		2439	skip builtin block graphics (-sbg)
		2440	separate highlightcolor support (-hc)
		2441
		2442	It also enables some non-essential features otherwise disabled, such as:
		2443
		2444	some round-trip time optimisations
		2445	nearest color allocation on pseudocolor screens
		2446	UTF8_STRING support for selection
		2447	sgr modes 90..97 and 100..107
		2448	backindex and forwardindex escape sequences
		2449	view change/zero scrollback escape sequences
		2450	locale switching escape sequence
		2451	window op and some xterm/OSC escape sequences
		2452	rectangular selections
		2453	trailing space removal for selections
		2454	verbose X error handling
		2455
		2456	=item --enable-iso14755 (default: on)
		2457
		2458	Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
		2459	F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
		2460	C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
		2461	this switch.
		2462
		2463	=item --enable-keepscrolling (default: on)
		2464
		2465	Add support for continual scrolling of the display when you hold
		2466	the mouse button down on a scrollbar arrow.
		2467
		2468	=item --enable-selectionscrolling (default: on)
		2469
		2470	Add support for scrolling when the selection moves to the top or
		2471	bottom of the screen.
		2472
		2473	=item --enable-mousewheel (default: on)
		2474
		2475	Add support for scrolling via mouse wheel or buttons 4 & 5.
		2476
		2477	=item --enable-slipwheeling (default: on)
		2478
		2479	Add support for continual scrolling (using the mouse wheel as an
		2480	accelerator) while the control key is held down. This option
		2481	requires --enable-mousewheel to also be specified.
		2482
		2483	=item --enable-smart-resize (default: off)
		2484
		2485	Add smart growth/shrink behaviour when resizing.
		2486	This should keep the window corner which is closest to a corner of
		2487	the screen in a fixed position.
		2488
		2489	=item --enable-pointer-blank (default: on)
		2490
		2491	Add support to have the pointer disappear when typing or inactive.
		2492
		2493	=item --enable-perl (default: on)
		2494
		2495	Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
		2496	manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the
		2497	files in F<src/perl-ext/> for the extensions that are installed by
		2498	default. The perl interpreter that is used can be specified via the
		2499	C<PERL> environment variable when running configure. Even when compiled
		2500	in, perl will I<not> be initialised when all extensions have been disabled
		2501	C<-pe "" --perl-ext-common "">, so it should be safe to enable from a
		2502	resource standpoint.
		2503
		2504	=item --with-afterimage-config=DIR
		2505
		2506	Look for the libAfterImage config script in DIR.
		2507
		2508	=item --with-name=NAME (default: urxvt)
		2509
		2510	Set the basename for the installed binaries, resulting
		2511	in C<urxvt>, C<urxvtd> etc.). Specify C<--with-name=rxvt> to replace with
		2512	C<rxvt>.
		2513
		2514	=item --with-term=NAME (default: rxvt-unicode)
		2515
		2516	Change the environmental variable for the terminal to NAME.
		2517
		2518	=item --with-terminfo=PATH
		2519
		2520	Change the environmental variable for the path to the terminfo tree to
		2521	PATH.
		2522
