		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>.

114	=item How do I know which rxvt-unicode version I'm using?	212	=head3 I can't get transparency working, what am I doing wrong?
115		213
116	The version number is displayed with the usage (-h). Also the escape	214	First of all, transparency isn't officially supported in rxvt-unicode, so

120		218
121	=item I am using Debian GNU/Linux and have a problem...	219	Here are four ways to get transparency. B<Do> read the manpage and option
		220	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
122		221
123	The Debian GNU/Linux package of rxvt-unicode in sarge contains large	222	1. Use inheritPixmap:
124	patches that considerably change the behaviour of rxvt-unicode. Before
125	reporting a bug to the original rxvt-unicode author please download and
126	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
127	and try to reproduce the problem. If you cannot, chances are that the
128	problems are specific to Debian GNU/Linux, in which case it should be
129	reported via the Debian Bug Tracking System (use C<reportbug> to report
130	the bug).
131		223
132	For other problems that also affect the Debian package, you can and	224	Esetroot wallpaper.jpg
133	probably should use the Debian BTS, too, because, after all, it's also a	225	@@URXVT_NAME@@ -ip -tint red -sh 40
134	bug in the Debian version and it serves as a reminder for other users that
135	might encounter the same issue.
136		226
		227	That works. If you think it doesn't, you lack transparency and tinting
		228	support, or you are unable to read.
		229
		230	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		231	to use effects other than tinting and shading: Just shade/tint/whatever
		232	your picture with gimp or any other tool:
		233
		234	convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
		235	@@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
		236
		237	That works. If you think it doesn't, you lack XPM and Perl support, or you
		238	are unable to read.
		239
		240	3. Use an ARGB visual:
		241
		242	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		243
		244	This requires XFT support, and the support of your X-server. If that
		245	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		246	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		247	bugfixes and workarounds for Xft and Xlib to make it work, but that
		248	doesn't mean that your WM has the required kludges in place.
		249
		250	4. Use xcompmgr and let it do the job:
		251
		252	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		253	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		254
		255	Then click on a window you want to make transparent. Replace C<0xc0000000>
		256	by other values to change the degree of opacity. If it doesn't work and
		257	your server crashes, you got to keep the pieces.
		258
		259	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		260
		261	Most fonts were not designed for terminal use, which means that character
		262	size varies a lot. A font that is otherwise fine for terminal use might
		263	contain some characters that are simply too wide. Rxvt-unicode will avoid
		264	these characters. For characters that are just "a bit" too wide a special
		265	"careful" rendering mode is used that redraws adjacent characters.
		266
		267	All of this requires that fonts do not lie about character sizes,
		268	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		269	box, and rxvt-unicode has no way of detecting this (the correct way is to
		270	ask for the character bounding box, which unfortunately is wrong in these
		271	cases).
		272
		273	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		274	or the respective font. If you encounter this problem you might try using
		275	the C<-lsp> option to give the font more height. If that doesn't work, you
		276	might be forced to use a different font.
		277
		278	All of this is not a problem when using X11 core fonts, as their bounding
		279	box data is correct.
		280
		281	=head3 How can I keep rxvt-unicode from using reverse video so much?
		282
		283	First of all, make sure you are running with the right terminal settings
		284	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		285	make sure you have specified colours for italic and bold, as otherwise
		286	rxvt-unicode might use reverse video to simulate the effect:
		287
		288	URxvt.colorBD: white
		289	URxvt.colorIT: green
		290
		291	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		292
		293	For some unexplainable reason, some rare programs assume a very weird
		294	colour palette when confronted with a terminal with more than the standard
		295	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		296	these programs not to assume non-ISO colours without very good reasons.
		297
		298	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		299	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		300	fix colours but keep you from using other rxvt-unicode features.
		301
		302	=head3 Can I switch the fonts at runtime?
		303
		304	Yes, using an escape sequence. Try something like this, which has the same
		305	effect as using the C<-fn> switch, and takes effect immediately:
		306
		307	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		308
		309	This is useful if you e.g. work primarily with japanese (and prefer a
		310	japanese font), but you have to switch to chinese temporarily, where
		311	japanese fonts would only be in your way.
		312
		313	You can think of this as a kind of manual ISO-2022 switching.
		314
		315	=head3 Why do italic characters look as if clipped?
		316
		317	Many fonts have difficulties with italic characters and hinting. For
		318	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		319	Mono> completely fails in its italic face. A workaround might be to
		320	enable freetype autohinting, i.e. like this:
		321
		322	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		323	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		324
		325	=head3 Can I speed up Xft rendering somehow?
		326
		327	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		328	it is simply slow. If you still want Xft fonts you might try to disable
		329	antialiasing (by appending C<:antialias=false>), which saves lots of
		330	memory and also speeds up rendering considerably.
		331
		332	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		333
		334	Rxvt-unicode will use whatever you specify as a font. If it needs to
		335	fall back to its default font search list it will prefer X11 core
		336	fonts, because they are small and fast, and then use Xft fonts. It has
		337	antialiasing disabled for most of them, because the author thinks they
		338	look best that way.
		339
		340	If you want antialiasing, you have to specify the fonts manually.
		341
		342	=head3 What's with this bold/blink stuff?
		343
		344	If no bold colour is set via C<colorBD:>, bold will invert text using the
		345	standard foreground colour.
		346
		347	For the standard background colour, blinking will actually make the
		348	text blink when compiled with C<--enable-blinking>. with standard
		349	colours. Without C<--enable-blinking>, the blink attribute will be
		350	ignored.
		351
		352	On ANSI colours, bold/blink attributes are used to set high-intensity
		353	foreground/background colors.
		354
		355	color0-7 are the low-intensity colors.
		356
		357	color8-15 are the corresponding high-intensity colors.
		358
		359	=head3 I don't like the screen colors. How do I change them?
		360
		361	You can change the screen colors at run-time using F<~/.Xdefaults>
		362	resources (or as long-options).
		363
		364	Here are values that are supposed to resemble a VGA screen,
		365	including the murky brown that passes for low-intensity yellow:
		366
		367	URxvt.color0: #000000
		368	URxvt.color1: #A80000
		369	URxvt.color2: #00A800
		370	URxvt.color3: #A8A800
		371	URxvt.color4: #0000A8
		372	URxvt.color5: #A800A8
		373	URxvt.color6: #00A8A8
		374	URxvt.color7: #A8A8A8
		375
		376	URxvt.color8: #000054
		377	URxvt.color9: #FF0054
		378	URxvt.color10: #00FF54
		379	URxvt.color11: #FFFF54
		380	URxvt.color12: #0000FF
		381	URxvt.color13: #FF00FF
		382	URxvt.color14: #00FFFF
		383	URxvt.color15: #FFFFFF
		384
		385	And here is a more complete set of non-standard colors.
		386
		387	URxvt.cursorColor: #dc74d1
		388	URxvt.pointerColor: #dc74d1
		389	URxvt.background: #0e0e0e

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

		643
		644	See some more examples in the documentation for the B<keysym> resource.
		645
		646	=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
		647
		648	KP_Insert == Insert
		649	F22 == Print
		650	F27 == Home
		651	F29 == Prior
		652	F33 == End
		653	F35 == Next
		654
		655	Rather than have rxvt-unicode try to accommodate all the various possible
		656	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		657	required for your particular machine.
		658
		659
		660
		661	=head2 Terminal Configuration
		662
		663	=head3 Can I see a typical configuration?
		664
		665	The default configuration tries to be xterm-like, which I don't like that
		666	much, but it's least surprise to regular users.
		667
		668	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		669	time into customising your terminal. To get you started, here is the
		670	author's .Xdefaults entries, with comments on what they do. It's certainly
		671	not I<typical>, but what's typical...
		672
		673	URxvt.cutchars: "()*,<>[]{}|'
		674	URxvt.print-pipe: cat >/tmp/xxx
		675
		676	These are just for testing stuff.
		677
		678	URxvt.imLocale: ja_JP.UTF-8
		679	URxvt.preeditType: OnTheSpot,None
		680
		681	This tells rxvt-unicode to use a special locale when communicating with
		682	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		683	type, which requires the C<xim-onthespot> perl extension but rewards me
		684	with correct-looking fonts.
		685
		686	URxvt.perl-lib: /root/lib/urxvt
		687	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		688	URxvt.selection.pattern-0: ( at .*? line \\d+)
		689	URxvt.selection.pattern-1: ^(/[^:]+):\
		690	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		691	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		692
		693	This is my perl configuration. The first two set the perl library
		694	directory and also tells urxvt to use a large number of extensions. I
		695	develop for myself mostly, so I actually use most of the extensions I
		696	write.
		697
		698	The selection stuff mainly makes the selection perl-error-message aware
		699	and tells it to convert perl error messages into vi-commands to load the
		700	relevant file and go tot he error line number.
		701
		702	URxvt.scrollstyle: plain
		703	URxvt.secondaryScroll: true
		704
		705	As the documentation says: plain is the preferred scrollbar for the
		706	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		707	apps, like screen, so lines scrolled out of screen end up in urxvt's
		708	scrollback buffer.
		709
		710	URxvt.background: #000000
		711	URxvt.foreground: gray90
		712	URxvt.color7: gray90
		713	URxvt.colorBD: #ffffff
		714	URxvt.cursorColor: #e0e080
		715	URxvt.throughColor: #8080f0
		716	URxvt.highlightColor: #f0f0f0
		717
		718	Some colours. Not sure which ones are being used or even non-defaults, but
		719	these are in my .Xdefaults. Most notably, they set foreground/background
		720	to light gray/black, and also make sure that the colour 7 matches the
		721	default foreground colour.
		722
		723	URxvt.underlineColor: yellow
		724
		725	Another colour, makes underline lines look different. Sometimes hurts, but
		726	is mostly a nice effect.
		727
		728	URxvt.geometry: 154x36
		729	URxvt.loginShell: false
		730	URxvt.meta: ignore
		731	URxvt.utmpInhibit: true
		732
		733	Uh, well, should be mostly self-explanatory. By specifying some defaults
		734	manually, I can quickly switch them for testing.
		735
		736	URxvt.saveLines: 8192
		737
		738	A large scrollback buffer is essential. Really.
		739
		740	URxvt.mapAlert: true
		741
		742	The only case I use it is for my IRC window, which I like to keep
		743	iconified till people msg me (which beeps).

		765	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		766
		767	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		768	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		769	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		770	font (different glyphs for C<;> and many other harmless characters),
		771	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		772	bold version has less chars than the medium version, so I use it for rare
		773	characters, too. When editing sources with vim, I use italic for comments
		774	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		775
		776	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		777	purposes, it works, and gives a different look, as my normal (Non-bold)
		778	font is already bold, and I want to see a difference between bold and
		779	normal fonts.
		780
		781	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		782	class name. Thats because I use different configs for different purposes,
		783	for example, my IRC window is started with C<-name IRC>, and uses these
		784	defaults:
		785
		786	IRC*title: IRC
		787	IRC*geometry: 87x12+535+542
		788	IRC*saveLines: 0
		789	IRC*mapAlert: true
		790	IRC*font: suxuseuro

		792	IRC*colorBD: white
		793	IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
		794	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		795
		796	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		797	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		798	stuff while keeping a very small window. If somebody pastes something
		799	complicated (e.g. japanese), I temporarily switch to a larger font.
		800
		801	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		802	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		803	file for different hosts, for example, on ym main desktop, I use:
		804
		805	URxvt.keysym.C-M-q: command:\033[3;5;5t
		806	URxvt.keysym.C-M-y: command:\033[3;5;606t
		807	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		808	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		809	URxvt.keysym.C-M-p: perl:test
		810
		811	The first for keysym definitions allow me to quickly bring some windows
		812	in the layout I like most. Ion users might start laughing but will stop
		813	immediately when I tell them that I use my own Fvwm2 module for much the
		814	same effect as Ion provides, and I only very rarely use the above key
		815	combinations :->
		816
		817	=head3 Why doesn't rxvt-unicode read my resources?
		818
		819	Well, why, indeed? It does, in a way very similar to other X
		820	applications. Most importantly, this means that if you or your OS loads
		821	resources into the X display (the right way to do it), rxvt-unicode will
		822	ignore any resource files in your home directory. It will only read
		823	F<$HOME/.Xdefaults> when no resources are attached to the display.
		824
		825	If you have or use an F<$HOME/.Xresources> file, chances are that
		826	resources are loaded into your X-server. In this case, you have to
		827	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		828
		829	Also consider the form resources have to use:
		830
		831	URxvt.resource: value
		832
		833	If you want to use another form (there are lots of different ways of
		834	specifying resources), make sure you understand whether and why it
		835	works. If unsure, use the form above.

309	=item Why do some chinese characters look so different than others?
310
311	This is because there is a difference between script and language --
312	rxvt-unicode does not know which language the text that is output is,
313	as it only knows the unicode character codes. If rxvt-unicode first
314	sees a japanese/chinese character, it might choose a japanese font for
315	display. Subsequent japanese characters will use that font. Now, many
316	chinese characters aren't represented in japanese fonts, so when the first
317	non-japanese character comes up, rxvt-unicode will look for a chinese font
318	-- unfortunately at this point, it will still use the japanese font for
319	chinese characters that are also in the japanese font.
320
321	The workaround is easy: just tag a chinese font at the end of your font
322	list (see the previous question). The key is to view the font list as
323	a preference list: If you expect more japanese, list a japanese font
324	first. If you expect more chinese, put a chinese font first.
325
326	In the future it might be possible to switch language preferences at
327	runtime (the internal data structure has no problem with using different
328	fonts for the same character at the same time, but no interface for this
329	has been designed yet).
330
331	Until then, you might get away with switching fonts at runtime (see L<Can
332	I switch the fonts at runtime?> later in this document).
333
334	=item Why does rxvt-unicode sometimes leave pixel droppings?
335
336	Most fonts were not designed for terminal use, which means that character
337	size varies a lot. A font that is otherwise fine for terminal use might
338	contain some characters that are simply too wide. Rxvt-unicode will avoid
339	these characters. For characters that are just "a bit" too wide a special
340	"careful" rendering mode is used that redraws adjacent characters.
341
342	All of this requires that fonts do not lie about character sizes,
343	however: Xft fonts often draw glyphs larger than their acclaimed bounding
344	box, and rxvt-unicode has no way of detecting this (the correct way is to

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

456		1202
457	=item Is there an option to switch encodings?	1203	urxvt uses the system wcwidth function to know the information about
		1204	the width of characters, so on systems with incorrect locale data you
		1205	will likely get bad results. Two notorious examples are Solaris 9,
		1206	where single-width characters like U+2514 are reported as double-width,
		1207	and Darwin 8, where combining chars are reported having width 1.

461	UTF-8 or any other encodings with respect to terminal I/O.
462		1211
463	The reasons is that there exists a perfectly fine mechanism for selecting	1212	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
464	the encoding, doing I/O and (most important) communicating this to all
465	applications so everybody agrees on character properties such as width
466	and code number. This mechanism is the I<locale>. Applications not using
467	that info will have problems (for example, C<xterm> gets the width of
468	characters wrong as it uses it's own, locale-independent table under all
469	locales).
470		1213
471	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
472	programs doing the same (that is, most) will automatically agree in the
473	interpretation of characters.
474
475	Unfortunately, there is no system-independent way to select locales, nor
476	is there a standard on how locale specifiers will look like.
477
478	On most systems, the content of the C<LC_CTYPE> environment variable
479	contains an arbitrary string which corresponds to an already-installed
480	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
481	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
482	(i.e. C<de> or C<german>) are also common.
483
484	Rxvt-unicode ignores all other locale categories, and except for
485	the encoding, ignores country or language-specific settings,
486	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
487	rxvt-unicode.
488
489	If you want to use a specific encoding you have to make sure you start
490	rxvt-unicode with the correct C<LC_CTYPE> category.
491
492	=item Can I switch locales at runtime?
493
494	Yes, using an escape sequence. Try something like this, which sets
495	rxvt-unicode's idea of C<LC_CTYPE>.
496
497	printf '\e]701;%s\007' ja_JP.SJIS
498
499	See also the previous answer.
500
501	Sometimes this capability is rather handy when you want to work in
502	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
503	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
504	first switches to a locale supported by xjdic and back later:
505
506	printf '\e]701;%s\007' ja_JP.SJIS
507	xjdic -js
508	printf '\e]701;%s\007' de_DE.UTF-8
509
510	You can also use xterm's C<luit> program, which usually works fine, except
511	for some locales where character width differs between program- and
512	rxvt-unicode-locales.
513
514	=item Can I switch the fonts at runtime?
515
516	Yes, using an escape sequence. Try something like this, which has the same
517	effect as using the C<-fn> switch, and takes effect immediately:
518
519	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
520
521	This is useful if you e.g. work primarily with japanese (and prefer a
522	japanese font), but you have to switch to chinese temporarily, where
523	japanese fonts would only be in your way.
524
525	You can think of this as a kind of manual ISO-2022 switching.
526
527	=item Why do italic characters look as if clipped?
528
529	Many fonts have difficulties with italic characters and hinting. For
530	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
531	Mono> completely fails in it's italic face. A workaround might be to
532	enable freetype autohinting, i.e. like this:
533
534	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
535	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
536
537	=item My input method wants <some encoding> but I want UTF-8, what can I do?
538
539	You can specify separate locales for the input method and the rest of the
540	terminal, using the resource C<imlocale>:
541
542	URxvt*imlocale: ja_JP.EUC-JP
543
544	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
545	use your input method. Please note, however, that you will not be able to
546	input characters outside C<EUC-JP> in a normal way then, as your input
547	method limits you.
548
549	=item Rxvt-unicode crashes when the X Input Method changes or exits.
550
551	Unfortunately, this is unavoidable, as the XIM protocol is racy by
552	design. Applications can avoid some crashes at the expense of memory
553	leaks, and Input Methods can avoid some crashes by careful ordering at
554	exit time. B<kinput2> (and derived input methods) generally succeeds,
555	while B<SCIM> (or similar input methods) fails. In the end, however,
556	crashes cannot be completely avoided even if both sides cooperate.
557
558	So the only workaround is not to kill your Input Method Servers.
559
560	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
561
562	Rxvt-unicode tries to obey the rule of not charging you for something you
563	don't use. One thing you should try is to configure out all settings that
564	you don't need, for example, Xft support is a resource hog by design,
565	when used. Compiling it out ensures that no Xft font will be loaded
566	accidentally when rxvt-unicode tries to find a font for your characters.
567
568	Also, many people (me included) like large windows and even larger
569	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
570	6 bytes per screen cell. For a 160x?? window this amounts to almost a
571	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
572	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
573	rxvt-unicode then uses 8 bytes per screen cell.
574
575	=item Can I speed up Xft rendering somehow?
576
577	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
578	it is simply slow. If you still want Xft fonts you might try to disable
579	antialiasing (by appending C<:antialias=false>), which saves lots of
580	memory and also speeds up rendering considerably.
581
582	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
583
584	Rxvt-unicode will use whatever you specify as a font. If it needs to
585	fall back to it's default font search list it will prefer X11 core
586	fonts, because they are small and fast, and then use Xft fonts. It has
587	antialiasing disabled for most of them, because the author thinks they
588	look best that way.
589
590	If you want antialiasing, you have to specify the fonts manually.
591

599
600	=item What's with this bold/blink stuff?
601
602	If no bold colour is set via C<colorBD:>, bold will invert text using the
603	standard foreground colour.
604
605	For the standard background colour, blinking will actually make the
606	text blink when compiled with C<--enable-blinking>. with standard
607	colours. Without C<--enable-blinking>, the blink attribute will be
608	ignored.
609
610	On ANSI colours, bold/blink attributes are used to set high-intensity
611	foreground/background colors.
612
613	color0-7 are the low-intensity colors.
614
615	color8-15 are the corresponding high-intensity colors.

670	=item What's with the strange Backspace/Delete key behaviour?
671
672	Assuming that the physical Backspace key corresponds to the
673	BackSpace keysym (not likely for Linux ... see the following
674	question) there are two standard values that can be used for
675	Backspace: C<^H> and C<^?>.
676
677	Historically, either value is correct, but rxvt-unicode adopts the debian
678	policy of using C<^?> when unsure, because it's the one only only correct
679	choice :).
680
681	Rxvt-unicode tries to inherit the current stty settings and uses the value
682	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
683	started from a terminal (say, from a menu or by remote shell), then the
684	system value of `erase', which corresponds to CERASE in <termios.h>, will
685	be used (which may not be the same as your stty setting).
686
687	For starting a new rxvt-unicode:
688
689	# use Backspace = ^H
690	$ stty erase ^H
691	$ @@RXVT_NAME@@
692
693	# use Backspace = ^?

695	$ @@RXVT_NAME@@
696
697	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
698
699	For an existing rxvt-unicode:
700
701	# use Backspace = ^H
702	$ stty erase ^H
703	$ echo -n "^[[36h"
704
705	# use Backspace = ^?
706	$ stty erase ^?
707	$ echo -n "^[[36l"
708
709	This helps satisfy some of the Backspace discrepancies that occur, but
710	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
711	properly reflects that.
712
713	The Delete key is a another casualty of the ill-defined Backspace problem.
714	To avoid confusion between the Backspace and Delete keys, the Delete
715	key has been assigned an escape sequence to match the vt100 for Execute
716	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
717
718	Some other Backspace problems:
719
720	some editors use termcap/terminfo,
721	some editors (vim I'm told) expect Backspace = ^H,
722	GNU Emacs (and Emacs-like editors) use ^H for help.

784	snippets to correctly set the display. If your version of rxvt-unicode
785	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
786	the COLORTERM variable can be used to distinguish rxvt-unicode from a
787	regular xterm.
788
789	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
790	snippets:
791
792	# Bourne/Korn/POSIX family of shells:
793	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
794	if [ ${TERM:-foo} = xterm ]; then
795	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
796	echo -n '^[Z'
797	read term_id
798	stty icanon echo
799	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
800	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
801	read DISPLAY # set it in our local shell

807	You need to have a recent version of perl installed as F</usr/bin/perl>,
808	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
809	the doc subdirectory and enter C<make alldoc>.

814	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be

1628
1629	B<< The exact syntax used is I<almost> solidified. >>
1630	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1631	menuBar.
1632
1633	Note that in all of the commands, the B<< I</path/> >> I<cannot> be
1634	omitted: use B<./> to specify a menu relative to the current menu.
1635
1636	=head2 Overview of menuBar operation
1637
1638	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1639	of C<Pt> can be used for a variety of tasks:
1640
1641	At the top level is the current menuBar which is a member of a circular
1642	linked-list of other such menuBars.
1643
1644	The menuBar acts as a parent for the various drop-down menus, which in
1645	turn, may have labels, separator lines, menuItems and subMenus.
1646
1647	The menuItems are the useful bits: you can use them to mimic keyboard
1648	input or even to send text or escape sequences back to rxvt.
1649
1650	The menuBar syntax is intended to provide a simple yet robust method of
1651	constructing and manipulating menus and navigating through the
1652	menuBars.
1653
1654	The first step is to use the tag B<< [menu:I<name>] >> which creates
1655	the menuBar called I<name> and allows access. You may now or menus,
1656	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1657	menuBar access as B<readonly> to prevent accidental corruption of the
1658	menus. To re-access the current menuBar for alterations, use the tag
1659	B<[menu]>, make the alterations and then use B<[done]>

1668
1669	access the named menuBar for creation or alteration. If a new menuBar
1670	is created, it is called I<name> (max of 15 chars) and the current
1671	menuBar is pushed onto the stack

1676
1677	=item B<< [title:+I<string>] >>
1678
1679	set the current menuBar's title to I<string>, which may contain the
1680	following format specifiers:
1681
1682	B<%n> rxvt name (as per the B<-name> command-line option)
1683	B<%v> rxvt version
1684	B<%%> literal B<%> character

1689	End-of-file tag for B<< [read:+I<file>] >> operations.
1690
1691	=item B<< [read:+I<file>] >>
1692
1693	read menu commands directly from I<file> (extension ".menu" will be
1694	appended if required.) Start reading at a line with B<[menu]> or B<<
1695	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1696
1697	Blank and comment lines (starting with B<#>) are ignored. Actually,
1698	since any invalid menu commands are also ignored, almost anything could
1699	be construed as a comment line, but this may be tightened up in the
1700	future ... so don't count on it!.

1829	To send a string starting with a B<NUL> (B<^@>) character to the

1831	the first of which will be stripped off and the balance directed to the
1832	program. Otherwise if I<action> begins with B<NUL> followed by
1833	non-+B<NUL> characters, the leading B<NUL> is stripped off and the
1834	balance is sent back to rxvt.
1835
1836	As a convenience for the many Emacs-type editors, I<action> may start
1837	with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
1838	appended if missed from B<M-x> commands.
1839
1840	As a convenience for issuing XTerm B<ESC ]> sequences from a menubar (or
