		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:

		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

144		220
145	The Debian GNU/Linux package of rxvt-unicode in sarge contains large	221	1. Use transparent mode:
146	patches that considerably change the behaviour of rxvt-unicode. Before
147	reporting a bug to the original rxvt-unicode author please download and
148	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
149	and try to reproduce the problem. If you cannot, chances are that the
150	problems are specific to Debian GNU/Linux, in which case it should be
151	reported via the Debian Bug Tracking System (use C<reportbug> to report
152	the bug).
153		222
154	For other problems that also affect the Debian package, you can and	223	Esetroot wallpaper.jpg
155	probably should use the Debian BTS, too, because, after all, it's also a	224	@@URXVT_NAME@@ -tr -tint red -sh 40
156	bug in the Debian version and it serves as a reminder for other users that
157	might encounter the same issue.
158		225
159	=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?	226	That works. If you think it doesn't, you lack transparency and tinting
		227	support, or you are unable to read.
160		228
161	You should build one binary with the default options. F<configure>	229	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
162	now enables most useful options, and the trend goes to making them	230	to use effects other than tinting and shading: Just shade/tint/whatever

164	except higher disk and possibly memory usage. The perl interpreter should
165	be enabled, as important functionality (menus, selection, likely more in
166	the future) depends on it.
167		232
168	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources	233	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
169	system-wide (except maybe with C<defaults>). This will result in useful	234	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
170	behaviour. If your distribution aims at low memory, add an empty
171	C<perl-ext-common> resource to the app-defaults file. This will keep the
172	perl interpreter disabled until the user enables it.
173		235
174	If you can/want build more binaries, I recommend building a minimal	236	That works. If you think it doesn't, you lack AfterImage support, or you

179	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?	239	3. Use an ARGB visual:
180		240

182	bad at it, I think it is simply unreasonable to expect all of freetype
183	+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
184	secure. Also, rxvt-unicode disables some options when it detects that it
185	runs setuid or setgid, which is not nice. Besides, with the embedded perl
186	interpreter the possibility for security problems easily multiplies.

		255	by other values to change the degree of opacity. If it doesn't work and
		256	your server crashes, you got to keep the pieces.
		257
		258	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		259
		260	Most fonts were not designed for terminal use, which means that character
		261	size varies a lot. A font that is otherwise fine for terminal use might
		262	contain some characters that are simply too wide. Rxvt-unicode will avoid
		263	these characters. For characters that are just "a bit" too wide a special
		264	"careful" rendering mode is used that redraws adjacent characters.
		265
		266	All of this requires that fonts do not lie about character sizes,
		267	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		268	box, and rxvt-unicode has no way of detecting this (the correct way is to
		269	ask for the character bounding box, which unfortunately is wrong in these
		270	cases).
		271
		272	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		273	or the respective font. If you encounter this problem you might try using
		274	the C<-lsp> option to give the font more height. If that doesn't work, you
		275	might be forced to use a different font.
		276
		277	All of this is not a problem when using X11 core fonts, as their bounding
		278	box data is correct.
		279
		280	=head3 How can I keep rxvt-unicode from using reverse video so much?
		281
		282	First of all, make sure you are running with the right terminal settings
		283	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		284	make sure you have specified colours for italic and bold, as otherwise
		285	rxvt-unicode might use reverse video to simulate the effect:
		286
		287	URxvt.colorBD: white
		288	URxvt.colorIT: green
		289
		290	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		291
		292	For some unexplainable reason, some rare programs assume a very weird
		293	colour palette when confronted with a terminal with more than the standard
		294	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		295	these programs not to assume non-ISO colours without very good reasons.
		296
		297	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		298	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		299	fix colours but keep you from using other rxvt-unicode features.
		300
		301	=head3 Can I switch the fonts at runtime?
		302
		303	Yes, using an escape sequence. Try something like this, which has the same
		304	effect as using the C<-fn> switch, and takes effect immediately:
		305
		306	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		307
		308	This is useful if you e.g. work primarily with japanese (and prefer a
		309	japanese font), but you have to switch to chinese temporarily, where
		310	japanese fonts would only be in your way.
		311
		312	You can think of this as a kind of manual ISO-2022 switching.
		313
		314	=head3 Why do italic characters look as if clipped?
		315
		316	Many fonts have difficulties with italic characters and hinting. For
		317	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		318	Mono> completely fails in its italic face. A workaround might be to
		319	enable freetype autohinting, i.e. like this:
		320
		321	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		322	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		323
		324	=head3 Can I speed up Xft rendering somehow?
		325
		326	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		327	it is simply slow. If you still want Xft fonts you might try to disable
		328	antialiasing (by appending C<:antialias=false>), which saves lots of
		329	memory and also speeds up rendering considerably.
		330
		331	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		332
		333	Rxvt-unicode will use whatever you specify as a font. If it needs to
		334	fall back to its default font search list it will prefer X11 core
		335	fonts, because they are small and fast, and then use Xft fonts. It has
		336	antialiasing disabled for most of them, because the author thinks they
		337	look best that way.
		338
		339	If you want antialiasing, you have to specify the fonts manually.
		340
		341	=head3 What's with this bold/blink stuff?
		342
		343	If no bold colour is set via C<colorBD:>, bold will invert text using the
		344	standard foreground colour.
		345
		346	For the standard background colour, blinking will actually make the
		347	text blink when compiled with C<--enable-blinking>. with standard
		348	colours. Without C<--enable-blinking>, the blink attribute will be
		349	ignored.
		350
		351	On ANSI colours, bold/blink attributes are used to set high-intensity
		352	foreground/background colors.
		353
		354	color0-7 are the low-intensity colors.
		355
		356	color8-15 are the corresponding high-intensity colors.
		357
		358	=head3 I don't like the screen colors. How do I change them?
		359
		360	You can change the screen colors at run-time using F<~/.Xdefaults>
		361	resources (or as long-options).
		362
		363	Here are values that are supposed to resemble a VGA screen,
		364	including the murky brown that passes for low-intensity yellow:
		365
		366	URxvt.color0: #000000
		367	URxvt.color1: #A80000
		368	URxvt.color2: #00A800
		369	URxvt.color3: #A8A800
		370	URxvt.color4: #0000A8
		371	URxvt.color5: #A800A8
		372	URxvt.color6: #00A8A8
		373	URxvt.color7: #A8A8A8
		374
		375	URxvt.color8: #000054
		376	URxvt.color9: #FF0054
		377	URxvt.color10: #00FF54
		378	URxvt.color11: #FFFF54
		379	URxvt.color12: #0000FF
		380	URxvt.color13: #FF00FF
		381	URxvt.color14: #00FFFF
		382	URxvt.color15: #FFFFFF
		383
		384	And here is a more complete set of non-standard colors.
		385
		386	URxvt.cursorColor: #dc74d1
		387	URxvt.pointerColor: #dc74d1
		388	URxvt.background: #0e0e0e
		389	URxvt.foreground: #4ad5e1
		390	URxvt.color0: #000000
		391	URxvt.color8: #8b8f93
		392	URxvt.color1: #dc74d1
		393	URxvt.color9: #dc74d1
		394	URxvt.color2: #0eb8c7
		395	URxvt.color10: #0eb8c7
		396	URxvt.color3: #dfe37e
		397	URxvt.color11: #dfe37e
		398	URxvt.color5: #9e88f0
		399	URxvt.color13: #9e88f0
		400	URxvt.color6: #73f7ff
		401	URxvt.color14: #73f7ff
		402	URxvt.color7: #e1dddd
		403	URxvt.color15: #e1dddd

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

		648	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
		649
		650	See some more examples in the documentation for the B<keysym> resource.
		651
		652	=head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How do I make use of them? For example, the Sun Keyboard type 4 has the following map
		653
		654	KP_Insert == Insert
		655	F22 == Print
		656	F27 == Home
		657	F29 == Prior
		658	F33 == End
		659	F35 == Next
		660
		661	Rather than have rxvt-unicode try to accommodate all the various possible
		662	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		663	required for your particular machine.
		664
		665
		666	=head2 Terminal Configuration
		667
		668	=head3 Can I see a typical configuration?
		669
		670	The default configuration tries to be xterm-like, which I don't like that
		671	much, but it's least surprise to regular users.
		672
		673	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		674	time into customising your terminal. To get you started, here is the
		675	author's .Xdefaults entries, with comments on what they do. It's certainly
		676	not I<typical>, but what's typical...
		677
		678	URxvt.cutchars: "()*,<>[]{}|'
		679	URxvt.print-pipe: cat >/tmp/xxx
		680
		681	These are just for testing stuff.
		682
		683	URxvt.imLocale: ja_JP.UTF-8
		684	URxvt.preeditType: OnTheSpot,None
		685
		686	This tells rxvt-unicode to use a special locale when communicating with
		687	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		688	type, which requires the C<xim-onthespot> perl extension but rewards me
		689	with correct-looking fonts.
		690
		691	URxvt.perl-lib: /root/lib/urxvt
		692	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard

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

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

		790
		791	IRC*title: IRC
		792	IRC*geometry: 87x12+535+542
		793	IRC*saveLines: 0

		800
		801	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		802	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		803	stuff while keeping a very small window. If somebody pastes something
		804	complicated (e.g. japanese), I temporarily switch to a larger font.
		805
		806	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		807	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		808	file for different hosts, for example, on ym main desktop, I use:
		809
		810	URxvt.keysym.C-M-q: command:\033[3;5;5t
		811	URxvt.keysym.C-M-y: command:\033[3;5;606t

		815
		816	The first for keysym definitions allow me to quickly bring some windows
		817	in the layout I like most. Ion users might start laughing but will stop
		818	immediately when I tell them that I use my own Fvwm2 module for much the

		822	=head3 Why doesn't rxvt-unicode read my resources?
		823
		824	Well, why, indeed? It does, in a way very similar to other X
		825	applications. Most importantly, this means that if you or your OS loads
		826	resources into the X display (the right way to do it), rxvt-unicode will
		827	ignore any resource files in your home directory. It will only read
		828	F<$HOME/.Xdefaults> when no resources are attached to the display.
		829
		830	If you have or use an F<$HOME/.Xresources> file, chances are that
		831	resources are loaded into your X-server. In this case, you have to
		832	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		833
		834	Also consider the form resources have to use:
		835
		836	URxvt.resource: value
		837
		838	If you want to use another form (there are lots of different ways of
		839	specifying resources), make sure you understand whether and why it
		840	works. If unsure, use the form above.

369
370	=item Why do some chinese characters look so different than others?
371
372	This is because there is a difference between script and language --
373	rxvt-unicode does not know which language the text that is output is,
374	as it only knows the unicode character codes. If rxvt-unicode first
375	sees a japanese/chinese character, it might choose a japanese font for
376	display. Subsequent japanese characters will use that font. Now, many
377	chinese characters aren't represented in japanese fonts, so when the first
378	non-japanese character comes up, rxvt-unicode will look for a chinese font
379	-- unfortunately at this point, it will still use the japanese font for
380	chinese characters that are also in the japanese font.
381
382	The workaround is easy: just tag a chinese font at the end of your font
383	list (see the previous question). The key is to view the font list as
384	a preference list: If you expect more japanese, list a japanese font
385	first. If you expect more chinese, put a chinese font first.
386
387	In the future it might be possible to switch language preferences at
388	runtime (the internal data structure has no problem with using different
389	fonts for the same character at the same time, but no interface for this
390	has been designed yet).
391
392	Until then, you might get away with switching fonts at runtime (see L<Can
393	I switch the fonts at runtime?> later in this document).
394
395	=item Why does rxvt-unicode sometimes leave pixel droppings?
396
397	Most fonts were not designed for terminal use, which means that character
398	size varies a lot. A font that is otherwise fine for terminal use might
399	contain some characters that are simply too wide. Rxvt-unicode will avoid
400	these characters. For characters that are just "a bit" too wide a special
401	"careful" rendering mode is used that redraws adjacent characters.
402
403	All of this requires that fonts do not lie about character sizes,
404	however: Xft fonts often draw glyphs larger than their acclaimed bounding
405	box, and rxvt-unicode has no way of detecting this (the correct way is to

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

518	=item Is there an option to switch encodings?	1208	urxvt uses the system wcwidth function to know the information about
		1209	the width of characters, so on systems with incorrect locale data you

522	UTF-8 or any other encodings with respect to terminal I/O.
523		1216
524	The reasons is that there exists a perfectly fine mechanism for selecting	1217	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
525	the encoding, doing I/O and (most important) communicating this to all
526	applications so everybody agrees on character properties such as width
527	and code number. This mechanism is the I<locale>. Applications not using
528	that info will have problems (for example, C<xterm> gets the width of
529	characters wrong as it uses it's own, locale-independent table under all
530	locales).
531		1218
532	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
533	programs doing the same (that is, most) will automatically agree in the
534	interpretation of characters.
535
536	Unfortunately, there is no system-independent way to select locales, nor
537	is there a standard on how locale specifiers will look like.
538
539	On most systems, the content of the C<LC_CTYPE> environment variable
540	contains an arbitrary string which corresponds to an already-installed
541	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
542	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
543	(i.e. C<de> or C<german>) are also common.
544
545	Rxvt-unicode ignores all other locale categories, and except for
546	the encoding, ignores country or language-specific settings,
547	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
548	rxvt-unicode.
549
550	If you want to use a specific encoding you have to make sure you start
551	rxvt-unicode with the correct C<LC_CTYPE> category.
552
553	=item Can I switch locales at runtime?
554
555	Yes, using an escape sequence. Try something like this, which sets
556	rxvt-unicode's idea of C<LC_CTYPE>.
557
558	printf '\e]701;%s\007' ja_JP.SJIS
559
560	See also the previous answer.
561
562	Sometimes this capability is rather handy when you want to work in
563	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
564	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
565	first switches to a locale supported by xjdic and back later:
566
567	printf '\e]701;%s\007' ja_JP.SJIS
568	xjdic -js
569	printf '\e]701;%s\007' de_DE.UTF-8
570
571	You can also use xterm's C<luit> program, which usually works fine, except
572	for some locales where character width differs between program- and
573	rxvt-unicode-locales.
574
575	=item Can I switch the fonts at runtime?
576
577	Yes, using an escape sequence. Try something like this, which has the same
578	effect as using the C<-fn> switch, and takes effect immediately:
579
580	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
581
582	This is useful if you e.g. work primarily with japanese (and prefer a
583	japanese font), but you have to switch to chinese temporarily, where
584	japanese fonts would only be in your way.
585
586	You can think of this as a kind of manual ISO-2022 switching.
587
588	=item Why do italic characters look as if clipped?
589
590	Many fonts have difficulties with italic characters and hinting. For
591	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
592	Mono> completely fails in it's italic face. A workaround might be to
593	enable freetype autohinting, i.e. like this:
594
595	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
596	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
597
598	=item My input method wants <some encoding> but I want UTF-8, what can I do?
599
600	You can specify separate locales for the input method and the rest of the
601	terminal, using the resource C<imlocale>:
602
603	URxvt*imlocale: ja_JP.EUC-JP
604
605	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
606	use your input method. Please note, however, that you will not be able to
607	input characters outside C<EUC-JP> in a normal way then, as your input
608	method limits you.
609
610	=item Rxvt-unicode crashes when the X Input Method changes or exits.
611

617	crashes cannot be completely avoided even if both sides cooperate.
618
619	So the only workaround is not to kill your Input Method Servers.
620
621	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
622
623	Rxvt-unicode tries to obey the rule of not charging you for something you
624	don't use. One thing you should try is to configure out all settings that
625	you don't need, for example, Xft support is a resource hog by design,
626	when used. Compiling it out ensures that no Xft font will be loaded
627	accidentally when rxvt-unicode tries to find a font for your characters.
628
629	Also, many people (me included) like large windows and even larger
630	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
631	6 bytes per screen cell. For a 160x?? window this amounts to almost a
632	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
633	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
634	rxvt-unicode then uses 8 bytes per screen cell.
635
636	=item Can I speed up Xft rendering somehow?
637
638	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
639	it is simply slow. If you still want Xft fonts you might try to disable
640	antialiasing (by appending C<:antialias=false>), which saves lots of
641	memory and also speeds up rendering considerably.
642
643	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
644
645	Rxvt-unicode will use whatever you specify as a font. If it needs to
646	fall back to it's default font search list it will prefer X11 core
647	fonts, because they are small and fast, and then use Xft fonts. It has
648	antialiasing disabled for most of them, because the author thinks they
649	look best that way.
650
651	If you want antialiasing, you have to specify the fonts manually.

660
661	=item What's with this bold/blink stuff?
662
663	If no bold colour is set via C<colorBD:>, bold will invert text using the

665
666	For the standard background colour, blinking will actually make the
667	text blink when compiled with C<--enable-blinking>. with standard
668	colours. Without C<--enable-blinking>, the blink attribute will be
669	ignored.
670
671	On ANSI colours, bold/blink attributes are used to set high-intensity
672	foreground/background colors.
673
674	color0-7 are the low-intensity colors.
675

732
733	Assuming that the physical Backspace key corresponds to the
734	BackSpace keysym (not likely for Linux ... see the following
735	question) there are two standard values that can be used for
736	Backspace: C<^H> and C<^?>.
737
738	Historically, either value is correct, but rxvt-unicode adopts the debian
739	policy of using C<^?> when unsure, because it's the one only only correct
740	choice :).
741
742	Rxvt-unicode tries to inherit the current stty settings and uses the value
743	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
744	started from a terminal (say, from a menu or by remote shell), then the
745	system value of `erase', which corresponds to CERASE in <termios.h>, will
746	be used (which may not be the same as your stty setting).
747
748	For starting a new rxvt-unicode:
749
750	# use Backspace = ^H
751	$ stty erase ^H
752	$ @@RXVT_NAME@@

765
766	# use Backspace = ^?

769
770	This helps satisfy some of the Backspace discrepancies that occur, but
771	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
772	properly reflects that.
773
774	The Delete key is a another casualty of the ill-defined Backspace problem.
775	To avoid confusion between the Backspace and Delete keys, the Delete
776	key has been assigned an escape sequence to match the vt100 for Execute
777	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.

779	Some other Backspace problems:
780
781	some editors use termcap/terminfo,
782	some editors (vim I'm told) expect Backspace = ^H,
783	GNU Emacs (and Emacs-like editors) use ^H for help.
784
785	Perhaps someday this will all be resolved in a consistent manner.

787	=item I don't like the key-bindings. How do I change them?
788
789	There are some compile-time selections available via configure. Unless
790	you have run "configure" with the C<--disable-resources> option you can
791	use the `keysym' resource to alter the keystrings associated with keysyms.
792
793	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
794
795	URxvt.keysym.Home: \033[1~
796	URxvt.keysym.End: \033[4~

818	=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
819	How do I make use of them? For example, the Sun Keyboard type 4
820	has the following mappings that rxvt-unicode doesn't recognize.
821
822	KP_Insert == Insert
823	F22 == Print
824	F27 == Home
825	F29 == Prior
826	F33 == End
827	F35 == Next
828
829	Rather than have rxvt-unicode try to accommodate all the various possible
830	keyboard mappings, it is better to use `xmodmap' to remap the keys as
831	required for your particular machine.
832
833	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
834	I need this to decide about setting colors etc.
835
836	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
837	check and see if that is set. Note that several programs, JED, slrn,
838	Midnight Commander automatically check this variable to decide whether or
839	not to use color.
840
841	=item How do I set the correct, full IP address for the DISPLAY variable?
842
843	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
844	insecure mode then it is possible to use the following shell script
845	snippets to correctly set the display. If your version of rxvt-unicode
846	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
847	the COLORTERM variable can be used to distinguish rxvt-unicode from a
848	regular xterm.
849
850	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
851	snippets:
852
853	# Bourne/Korn/POSIX family of shells:
854	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
855	if [ ${TERM:-foo} = xterm ]; then
856	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
857	echo -n '^[Z'
858	read term_id
859	stty icanon echo
860	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
861	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
862	read DISPLAY # set it in our local shell
863	fi
864	fi
865
866	=item How do I compile the manual pages for myself?
867
868	You need to have a recent version of perl installed as F</usr/bin/perl>,
869	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
870	the doc subdirectory and enter C<make alldoc>.

872	=item My question isn't answered here, can I ask a human?
873
874	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
875	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
876	interested in learning about new and exciting problems (but not FAQs :).

1692
1693	B<< The exact syntax used is I<almost> solidified. >>
1694	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1695	menuBar.
1696
1697	Note that in all of the commands, the B<< I</path/> >> I<cannot> be
1698	omitted: use B<./> to specify a menu relative to the current menu.
1699
1700	=head2 Overview of menuBar operation
1701
1702	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1703	of C<Pt> can be used for a variety of tasks:
1704
1705	At the top level is the current menuBar which is a member of a circular
1706	linked-list of other such menuBars.
1707
1708	The menuBar acts as a parent for the various drop-down menus, which in
1709	turn, may have labels, separator lines, menuItems and subMenus.
1710
1711	The menuItems are the useful bits: you can use them to mimic keyboard
1712	input or even to send text or escape sequences back to rxvt.
1713
1714	The menuBar syntax is intended to provide a simple yet robust method of
1715	constructing and manipulating menus and navigating through the
1716	menuBars.
1717
1718	The first step is to use the tag B<< [menu:I<name>] >> which creates
1719	the menuBar called I<name> and allows access. You may now or menus,
1720	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1721	menuBar access as B<readonly> to prevent accidental corruption of the
1722	menus. To re-access the current menuBar for alterations, use the tag
1723	B<[menu]>, make the alterations and then use B<[done]>

1733	access the named menuBar for creation or alteration. If a new menuBar
1734	is created, it is called I<name> (max of 15 chars) and the current
1735	menuBar is pushed onto the stack
1736
1737	=item B<[menu]>
1738
1739	access the current menuBar for alteration
1740
1741	=item B<< [title:+I<string>] >>
1742
1743	set the current menuBar's title to I<string>, which may contain the
1744	following format specifiers:
1745
1746	B<%n> rxvt name (as per the B<-name> command-line option)
1747	B<%v> rxvt version
1748	B<%%> literal B<%> character
1749
1750	=item B<[done]>
1751
1752	set menuBar access as B<readonly>.
1753	End-of-file tag for B<< [read:+I<file>] >> operations.
1754
1755	=item B<< [read:+I<file>] >>
1756
1757	read menu commands directly from I<file> (extension ".menu" will be
1758	appended if required.) Start reading at a line with B<[menu]> or B<<
1759	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1760
1761	Blank and comment lines (starting with B<#>) are ignored. Actually,
1762	since any invalid menu commands are also ignored, almost anything could
1763	be construed as a comment line, but this may be tightened up in the
1764	future ... so don't count on it!.

1893	To send a string starting with a B<NUL> (B<^@>) character to the

1895	the first of which will be stripped off and the balance directed to the

1897	non-+B<NUL> characters, the leading B<NUL> is stripped off and the
1898	balance is sent back to rxvt.
1899
1900	As a convenience for the many Emacs-type editors, I<action> may start
1901	with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
1902	appended if missed from B<M-x> commands.
1903
1904	As a convenience for issuing XTerm B<ESC ]> sequences from a menubar (or
