28	If you want to select e.g. alphanumeric words, you can use the following	30	=head2 Meta, Features & Commandline Issues

34	more and more.	35	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
		36	interested in learning about new and exciting problems (but not FAQs :).
35		37
36	To get a selection that is very similar to the old code, try this pattern:	38	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
37		39
38	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)	40	Beginning with version 7.3, there is a perl extension that implements a
		41	simple tabbed terminal. It is installed by default, so any of these should
		42	give you tabs:
39		43
40	Please also note that the I<LeftClick Shift-LeftClik> combination also	44	@@URXVT_NAME@@ -pe tabbed
41	selects words like the old code.
42		45
43	=head2 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
44
45	You can disable the perl extension completely by setting the
46	B<perl-ext-common> resource to the empty string, which also keeps
47	rxvt-unicode from initialising perl, saving memory.
48
49	If you only want to disable specific features, you first have to
50	identify which perl extension is responsible. For this, read the section
51	B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
52	example, to disable the B<selection-popup> and B<option-popup>, specify
53	this B<perl-ext-common> resource:
54
55	URxvt.perl-ext-common: default,-selection-popup,-option-popup
56
57	This will keep the default extensions, but disable the two popup
58	extensions. Some extensions can also be configured, for example,
59	scrollback search mode is triggered by B<M-s>. You can move it to any
60	other combination either by setting the B<searchable-scrollback> resource:
61
62	URxvt.searchable-scrollback: CM-s
63
64	=head2 The cursor moves when selecting text in the current input line, how do I switch this off?
65
66	See next entry.
67
68	=head2 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
69
70	These are caused by the C<readline> perl extension. Under normal
71	circumstances, it will move your cursor around when you click into the
72	line that contains it. It tries hard not to do this at the wrong moment,
73	but when running a program that doesn't parse cursor movements or in some
74	cases during rlogin sessions, it fails to detect this properly.
75
76	You can permamently switch this feature off by disabling the C<readline>
77	extension:
78
79	URxvt.perl-ext-common: default,-readline	46	URxvt.perl-ext-common: default,tabbed
80		47
81	=head2 Why doesn't rxvt-unicode read my resources?	48	It will also work fine with tabbing functionality of many window managers
		49	or similar tabbing programs, and its embedding-features allow it to be
		50	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		51	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		52	(murxvt) terminal as an example embedding application.
82		53
83	Well, why, indeed? It does, in a way very similar to other X	54	=head3 How do I know which rxvt-unicode version I'm using?
84	applications. Most importantly, this means that if you or your OS loads
85	resources into the X display (the right way to do it), rxvt-unicode will
86	ignore any resource files in your home directory. It will only read
87	F<$HOME/.Xdefaults> when no resources are attached to the display.
88		55
89	If you have or use an F<$HOME/.Xresources> file, chances are that	56	The version number is displayed with the usage (-h). Also the escape

		59	daemon.
92		60
93	Also consider the form resources have to use:	61	=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
94		62
95	URxvt.resource: value	63	Rxvt-unicode tries to obey the rule of not charging you for something you
		64	don't use. One thing you should try is to configure out all settings that
		65	you don't need, for example, Xft support is a resource hog by design,
		66	when used. Compiling it out ensures that no Xft font will be loaded
		67	accidentally when rxvt-unicode tries to find a font for your characters.
96		68
97	If you want to use another form (there are lots of different ways of	69	Also, many people (me included) like large windows and even larger

		72	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		73	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		74	rxvt-unicode then uses 8 bytes per screen cell.
100		75
101	=head2 I can't get transparency working, what am I doing wrong?	76	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
102		77
103	First of all, transparency isn't officially supported in rxvt-unicode, so	78	Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the

110		82
111	1. Use inheritPixmap:	83	If you want to start @@URXVT_NAME@@d automatically whenever you run

224	=head2 Does it support tabs, can I have a tabbed rxvt-unicode?
225		212
226	Beginning with version 7.3, there is a perl extension that implements a	213	=head2 Rendering, Font & Look and Feel Issues
227	simple tabbed terminal. It is installed by default, so any of these should
228	give you tabs:
229		214
230	@@RXVT_NAME@@ -pe tabbed	215	=head3 I can't get transparency working, what am I doing wrong?
231		216
		217	First of all, please address all transparency related issues to Sasha Vasko at
		218	sasha@aftercode.net and do not bug the author about it. Also, if you can't
		219	get it working consider it a rite of passage: ... and you failed.
		220
		221	Here are four ways to get transparency. B<Do> read the manpage and option
		222	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		223
		224	1. Use transparent mode:
		225
		226	Esetroot wallpaper.jpg
		227	@@URXVT_NAME@@ -tr -tint red -sh 40
		228
		229	That works. If you think it doesn't, you lack transparency and tinting
		230	support, or you are unable to read.
		231
		232	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		233	to use effects other than tinting and shading: Just shade/tint/whatever
		234	your picture with gimp or any other tool:
		235
		236	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		237	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
		238
		239	That works. If you think it doesn't, you lack AfterImage support, or you
		240	are unable to read.
		241
		242	3. Use an ARGB visual:
		243
		244	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		245
		246	This requires XFT support, and the support of your X-server. If that
		247	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		248	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		249	bugfixes and workarounds for Xft and Xlib to make it work, but that
		250	doesn't mean that your WM has the required kludges in place.
		251
		252	4. Use xcompmgr and let it do the job:
		253
		254	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		255	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		256
		257	Then click on a window you want to make transparent. Replace C<0xc0000000>
		258	by other values to change the degree of opacity. If it doesn't work and
		259	your server crashes, you got to keep the pieces.
		260
		261	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		262
		263	Most fonts were not designed for terminal use, which means that character
		264	size varies a lot. A font that is otherwise fine for terminal use might
		265	contain some characters that are simply too wide. Rxvt-unicode will avoid
		266	these characters. For characters that are just "a bit" too wide a special
		267	"careful" rendering mode is used that redraws adjacent characters.
		268
		269	All of this requires that fonts do not lie about character sizes,
		270	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		271	box, and rxvt-unicode has no way of detecting this (the correct way is to
		272	ask for the character bounding box, which unfortunately is wrong in these
		273	cases).
		274
		275	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		276	or the respective font. If you encounter this problem you might try using
		277	the C<-lsp> option to give the font more height. If that doesn't work, you
		278	might be forced to use a different font.
		279
		280	All of this is not a problem when using X11 core fonts, as their bounding
		281	box data is correct.
		282
		283	=head3 How can I keep rxvt-unicode from using reverse video so much?
		284
		285	First of all, make sure you are running with the right terminal settings
		286	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		287	make sure you have specified colours for italic and bold, as otherwise
		288	rxvt-unicode might use reverse video to simulate the effect:
		289
		290	URxvt.colorBD: white
		291	URxvt.colorIT: green
		292
		293	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		294
		295	For some unexplainable reason, some rare programs assume a very weird
		296	colour palette when confronted with a terminal with more than the standard
		297	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		298	these programs not to assume non-ISO colours without very good reasons.
		299
		300	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		301	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		302	fix colours but keep you from using other rxvt-unicode features.
		303
		304	=head3 Can I switch the fonts at runtime?
		305
		306	Yes, using an escape sequence. Try something like this, which has the same
		307	effect as using the C<-fn> switch, and takes effect immediately:
		308
		309	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		310
		311	This is useful if you e.g. work primarily with japanese (and prefer a
		312	japanese font), but you have to switch to chinese temporarily, where
		313	japanese fonts would only be in your way.
		314
		315	You can think of this as a kind of manual ISO-2022 switching.
		316
		317	=head3 Why do italic characters look as if clipped?
		318
		319	Many fonts have difficulties with italic characters and hinting. For
		320	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		321	Mono> completely fails in its italic face. A workaround might be to
		322	enable freetype autohinting, i.e. like this:

		325	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		326
		327	=head3 Can I speed up Xft rendering somehow?
		328
		329	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		330	it is simply slow. If you still want Xft fonts you might try to disable
		331	antialiasing (by appending C<:antialias=false>), which saves lots of
		332	memory and also speeds up rendering considerably.
		333
		334	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		335
		336	Rxvt-unicode will use whatever you specify as a font. If it needs to
		337	fall back to its default font search list it will prefer X11 core
		338	fonts, because they are small and fast, and then use Xft fonts. It has
		339	antialiasing disabled for most of them, because the author thinks they
		340	look best that way.
		341
		342	If you want antialiasing, you have to specify the fonts manually.
		343
		344	=head3 What's with this bold/blink stuff?
		345
		346	If no bold colour is set via C<colorBD:>, bold will invert text using the
		347	standard foreground colour.
		348
		349	For the standard background colour, blinking will actually make
		350	the text blink when compiled with C<--enable-text-blink>. Without
		351	C<--enable-text-blink>, the blink attribute will be ignored.
		352
		353	On ANSI colours, bold/blink attributes are used to set high-intensity
		354	foreground/background colors.
		355
		356	color0-7 are the low-intensity colors.
		357
		358	color8-15 are the corresponding high-intensity colors.
		359
		360	=head3 I don't like the screen colors. How do I change them?
		361
		362	You can change the screen colors at run-time using F<~/.Xdefaults>
		363	resources (or as long-options).
		364
		365	Here are values that are supposed to resemble a VGA screen,
		366	including the murky brown that passes for low-intensity yellow:
		367
		368	URxvt.color0: #000000
		369	URxvt.color1: #A80000
		370	URxvt.color2: #00A800

		374	URxvt.color6: #00A8A8
		375	URxvt.color7: #A8A8A8
		376
		377	URxvt.color8: #000054
		378	URxvt.color9: #FF0054
		379	URxvt.color10: #00FF54
		380	URxvt.color11: #FFFF54
		381	URxvt.color12: #0000FF

		383	URxvt.color14: #00FFFF
		384	URxvt.color15: #FFFFFF
		385
		386	And here is a more complete set of non-standard colors.

		409	=head3 Why do some characters look so much different than others?
		410
		411	See next entry.
		412
		413	=head3 How does rxvt-unicode choose fonts?
		414
		415	Most fonts do not contain the full range of Unicode, which is
		416	fine. Chances are that the font you (or the admin/package maintainer of
		417	your system/os) have specified does not cover all the characters you want
		418	to display.
		419
		420	B<rxvt-unicode> makes a best-effort try at finding a replacement
		421	font. Often the result is fine, but sometimes the chosen font looks
		422	bad/ugly/wrong. Some fonts have totally strange characters that don't
		423	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		424	intelligence to detect that a specific glyph is wrong: it has to believe
		425	the font that the characters it claims to contain indeed look correct.
		426
		427	In that case, select a font of your taste and add it to the font list,
		428	e.g.:
		429
		430	@@URXVT_NAME@@ -fn basefont,font2,font3...
		431
		432	When rxvt-unicode sees a character, it will first look at the base
		433	font. If the base font does not contain the character, it will go to the
		434	next font, and so on. Specifying your own fonts will also speed up this
		435	search and use less resources within rxvt-unicode and the X-server.
		436
		437	The only limitation is that none of the fonts may be larger than the base
		438	font, as the base font defines the terminal character cell size, which
		439	must be the same due to the way terminals work.
		440
		441	=head3 Why do some chinese characters look so different than others?
		442
		443	This is because there is a difference between script and language --
		444	rxvt-unicode does not know which language the text that is output is,
		445	as it only knows the unicode character codes. If rxvt-unicode first
		446	sees a japanese/chinese character, it might choose a japanese font for
		447	display. Subsequent japanese characters will use that font. Now, many
		448	chinese characters aren't represented in japanese fonts, so when the first
		449	non-japanese character comes up, rxvt-unicode will look for a chinese font
		450	-- unfortunately at this point, it will still use the japanese font for
		451	chinese characters that are also in the japanese font.
		452
		453	The workaround is easy: just tag a chinese font at the end of your font
		454	list (see the previous question). The key is to view the font list as
		455	a preference list: If you expect more japanese, list a japanese font
		456	first. If you expect more chinese, put a chinese font first.
		457
		458	In the future it might be possible to switch language preferences at
		459	runtime (the internal data structure has no problem with using different
		460	fonts for the same character at the same time, but no interface for this
		461	has been designed yet).
		462
		463	Until then, you might get away with switching fonts at runtime (see L<Can
		464	I switch the fonts at runtime?> later in this document).
		465
		466	=head3 How can I make mplayer display video correctly?
		467
		468	We are working on it, in the meantime, as a workaround, use something like:

		474
		475	=head3 The new selection selects pieces that are too big, how can I select single words?
		476
		477	If you want to select e.g. alphanumeric words, you can use the following
		478	setting:
		479
		480	URxvt.selection.pattern-0: ([[:word:]]+)
		481
		482	If you click more than twice, the selection will be extended
		483	more and more.
		484
		485	To get a selection that is very similar to the old code, try this pattern:
		486
		487	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		488
		489	Please also note that the I<LeftClick Shift-LeftClick> combination also
		490	selects words like the old code.
		491
		492	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		493
		494	You can disable the perl extension completely by setting the
		495	B<perl-ext-common> resource to the empty string, which also keeps
		496	rxvt-unicode from initialising perl, saving memory.
		497
		498	If you only want to disable specific features, you first have to
		499	identify which perl extension is responsible. For this, read the section
		500	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		501	example, to disable the B<selection-popup> and B<option-popup>, specify
		502	this B<perl-ext-common> resource:
		503
		504	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		505
		506	This will keep the default extensions, but disable the two popup
		507	extensions. Some extensions can also be configured, for example,
		508	scrollback search mode is triggered by B<M-s>. You can move it to any
		509	other combination either by setting the B<searchable-scrollback> resource:
		510
		511	URxvt.searchable-scrollback: CM-s
		512
		513	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		514
		515	See next entry.
		516
		517	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		518
		519	These are caused by the C<readline> perl extension. Under normal
		520	circumstances, it will move your cursor around when you click into the
		521	line that contains it. It tries hard not to do this at the wrong moment,
		522	but when running a program that doesn't parse cursor movements or in some
		523	cases during rlogin sessions, it fails to detect this properly.
		524
		525	You can permanently switch this feature off by disabling the C<readline>
		526	extension:
		527
232	URxvt.perl-ext-common: default,tabbed	528	URxvt.perl-ext-common: default,-readline
233		529
234	It will also work fine with tabbing functionality of many window managers	530	=head3 My numerical keypad acts weird and generates differing output?
235	or similar tabbing programs, and its embedding-features allow it to be
236	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
237	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
238	(murxvt) terminal as an example embedding application.

		534	by the wrong C<TERM> setting, although the details of whether and how
		535	this can happen are unknown, as C<TERM=rxvt> should offer a compatible

		543	your input method. For example, if you specified B<OverTheSpot> and
		544	your input method (e.g. the default input method handling Compose keys)
		545	does not support this (for instance because it is not visual), then
		546	rxvt-unicode will continue without an input method.
248		547

		708
		709	URxvt.scrollstyle: plain
		710	URxvt.secondaryScroll: true
		711
		712	As the documentation says: plain is the preferred scrollbar for the
		713	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		714	apps, like screen, so lines scrolled out of screen end up in urxvt's

		724
		725	Some colours. Not sure which ones are being used or even non-defaults, but
		726	these are in my .Xdefaults. Most notably, they set foreground/background
		727	to light gray/black, and also make sure that the colour 7 matches the
		728	default foreground colour.
		729
		730	URxvt.underlineColor: yellow

		774	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		775	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		776	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		777	font (different glyphs for C<;> and many other harmless characters),
		778	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		779	bold version has less chars than the medium version, so I use it for rare
		780	characters, too. When editing sources with vim, I use italic for comments
		781	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		782
		783	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		784	purposes, it works, and gives a different look, as my normal (Non-bold)
		785	font is already bold, and I want to see a difference between bold and
		786	normal fonts.
		787
		788	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		789	class name. Thats because I use different configs for different purposes,
		790	for example, my IRC window is started with C<-name IRC>, and uses these
		791	defaults:
		792
		793	IRC*title: IRC
		794	IRC*geometry: 87x12+535+542
		795	IRC*saveLines: 0
		796	IRC*mapAlert: true

		801	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		802
		803	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		804	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		805	stuff while keeping a very small window. If somebody pastes something
		806	complicated (e.g. japanese), I temporarily switch to a larger font.
		807
		808	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		809	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		810	file for different hosts, for example, on ym main desktop, I use:
		811
		812	URxvt.keysym.C-M-q: command:\033[3;5;5t
		813	URxvt.keysym.C-M-y: command:\033[3;5;606t

		815	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		816	URxvt.keysym.C-M-p: perl:test
		817
		818	The first for keysym definitions allow me to quickly bring some windows
		819	in the layout I like most. Ion users might start laughing but will stop
		820	immediately when I tell them that I use my own Fvwm2 module for much the
		821	same effect as Ion provides, and I only very rarely use the above key
		822	combinations :->
		823
		824	=head3 Why doesn't rxvt-unicode read my resources?
		825
		826	Well, why, indeed? It does, in a way very similar to other X
		827	applications. Most importantly, this means that if you or your OS loads
		828	resources into the X display (the right way to do it), rxvt-unicode will
		829	ignore any resource files in your home directory. It will only read
		830	F<$HOME/.Xdefaults> when no resources are attached to the display.
		831
		832	If you have or use an F<$HOME/.Xresources> file, chances are that
		833	resources are loaded into your X-server. In this case, you have to
		834	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		835
		836	Also consider the form resources have to use:
		837
		838	URxvt.resource: value
		839
		840	If you want to use another form (there are lots of different ways of
		841	specifying resources), make sure you understand whether and why it
		842	works. If unsure, use the form above.

469	e.g.:
470
471	@@RXVT_NAME@@ -fn basefont,font2,font3...
472
473	When rxvt-unicode sees a character, it will first look at the base
474	font. If the base font does not contain the character, it will go to the
475	next font, and so on. Specifying your own fonts will also speed up this
476	search and use less resources within rxvt-unicode and the X-server.
477
478	The only limitation is that none of the fonts may be larger than the base
479	font, as the base font defines the terminal character cell size, which
480	must be the same due to the way terminals work.
481
482	=head2 Why do some chinese characters look so different than others?
483
484	This is because there is a difference between script and language --
485	rxvt-unicode does not know which language the text that is output is,
486	as it only knows the unicode character codes. If rxvt-unicode first
487	sees a japanese/chinese character, it might choose a japanese font for
488	display. Subsequent japanese characters will use that font. Now, many
489	chinese characters aren't represented in japanese fonts, so when the first
490	non-japanese character comes up, rxvt-unicode will look for a chinese font
491	-- unfortunately at this point, it will still use the japanese font for
492	chinese characters that are also in the japanese font.
493
494	The workaround is easy: just tag a chinese font at the end of your font
495	list (see the previous question). The key is to view the font list as
496	a preference list: If you expect more japanese, list a japanese font
497	first. If you expect more chinese, put a chinese font first.
498
499	In the future it might be possible to switch language preferences at
500	runtime (the internal data structure has no problem with using different
501	fonts for the same character at the same time, but no interface for this
502	has been designed yet).
503
504	Until then, you might get away with switching fonts at runtime (see L<Can
505	I switch the fonts at runtime?> later in this document).
506
507	=head2 Why does rxvt-unicode sometimes leave pixel droppings?
508
509	Most fonts were not designed for terminal use, which means that character
510	size varies a lot. A font that is otherwise fine for terminal use might
511	contain some characters that are simply too wide. Rxvt-unicode will avoid
512	these characters. For characters that are just "a bit" too wide a special
513	"careful" rendering mode is used that redraws adjacent characters.
514
515	All of this requires that fonts do not lie about character sizes,
516	however: Xft fonts often draw glyphs larger than their acclaimed bounding
517	box, and rxvt-unicode has no way of detecting this (the correct way is to
518	ask for the character bounding box, which unfortunately is wrong in these

539	The most common causes for this are that either your locale is not set	1033	Yes, using an escape sequence. Try something like this, which sets

543	does not support this (for instance because it is not visual), then
544	rxvt-unicode will continue without an input method.
545		1035
546	In this case either do not specify a B<preeditStyle> or specify more than	1036	printf '\33]701;%s\007' ja_JP.SJIS

		1108	=head2 Operating Systems / Package Maintaining
		1109
		1110	=head3 I am using Debian GNU/Linux and have a problem...
		1111
		1112	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		1113	patches that considerably change the behaviour of rxvt-unicode (but
		1114	unfortunately this notice has been removed). Before reporting a bug to
		1115	the original rxvt-unicode author please download and install the genuine
		1116	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		1117	the problem. If you cannot, chances are that the problems are specific to
		1118	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		1119	Tracking System (use C<reportbug> to report the bug).
		1120
		1121	For other problems that also affect the Debian package, you can and
		1122	probably should use the Debian BTS, too, because, after all, it's also a
		1123	bug in the Debian version and it serves as a reminder for other users that
		1124	might encounter the same issue.
		1125
		1126	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1127
		1128	You should build one binary with the default options. F<configure>
		1129	now enables most useful options, and the trend goes to making them
		1130	runtime-switchable, too, so there is usually no drawback to enabling them,
		1131	except higher disk and possibly memory usage. The perl interpreter should
		1132	be enabled, as important functionality (menus, selection, likely more in
		1133	the future) depends on it.
		1134
		1135	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1136	system-wide (except maybe with C<defaults>). This will result in useful
		1137	behaviour. If your distribution aims at low memory, add an empty
		1138	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1139	perl interpreter disabled until the user enables it.
		1140
		1141	If you can/want build more binaries, I recommend building a minimal
		1142	one with C<--disable-everything> (very useful) and a maximal one with
		1143	C<--enable-everything> (less useful, it will be very big due to a lot of
		1144	encodings built-in that increase download times and are rarely used).
		1145
		1146	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1147
		1148	It should be, starting with release 7.1. You are encouraged to properly
		1149	install urxvt with privileges necessary for your OS now.
		1150
		1151	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1152	into a helper process for privileged operations (pty handling on some
		1153	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1154	immediately. This is much safer than most other terminals that keep
		1155	privileges while running (but is more relevant to urxvt, as it contains
		1156	things as perl interpreters, which might be "helpful" to attackers).
		1157
		1158	This forking is done as the very first within main(), which is very early
		1159	and reduces possible bugs to initialisation code run before main(), or
		1160	things like the dynamic loader of your system, which should result in very
		1161	little risk.

627		1207
628	=head2 How does rxvt-unicode determine the encoding to use?	1208	=head3 Character widths are not correct.
629		1209
630	See next entry.	1210	urxvt uses the system wcwidth function to know the information about
		1211	the width of characters, so on systems with incorrect locale data you
		1212	will likely get bad results. Two notorious examples are Solaris 9,
		1213	where single-width characters like U+2514 are reported as double-width,
		1214	and Darwin 8, where combining chars are reported having width 1.
631		1215
632	=head2 Is there an option to switch encodings?	1216	The solution is to upgrade your system or switch to a better one. A
		1217	possibly working workaround is to use a wcwidth implementation like
633		1218
634	Unlike some other terminals, rxvt-unicode has no encoding switch, and no	1219	http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
635	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
636	UTF-8 or any other encodings with respect to terminal I/O.
637		1220
638	The reasons is that there exists a perfectly fine mechanism for selecting
639	the encoding, doing I/O and (most important) communicating this to all
640	applications so everybody agrees on character properties such as width
641	and code number. This mechanism is the I<locale>. Applications not using
642	that info will have problems (for example, C<xterm> gets the width of
643	characters wrong as it uses it's own, locale-independent table under all
644	locales).
645
646	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
647	programs doing the same (that is, most) will automatically agree in the
648	interpretation of characters.
649
650	Unfortunately, there is no system-independent way to select locales, nor
651	is there a standard on how locale specifiers will look like.
652
653	On most systems, the content of the C<LC_CTYPE> environment variable
654	contains an arbitrary string which corresponds to an already-installed
655	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
656	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
657	(i.e. C<de> or C<german>) are also common.
658
659	Rxvt-unicode ignores all other locale categories, and except for
660	the encoding, ignores country or language-specific settings,
661	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
662	rxvt-unicode.
663
664	If you want to use a specific encoding you have to make sure you start
665	rxvt-unicode with the correct C<LC_CTYPE> category.
666
667	=head2 Can I switch locales at runtime?
668
669	Yes, using an escape sequence. Try something like this, which sets
670	rxvt-unicode's idea of C<LC_CTYPE>.
671
672	printf '\e]701;%s\007' ja_JP.SJIS
673
674	See also the previous answer.
675
676	Sometimes this capability is rather handy when you want to work in
677	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
678	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
679	first switches to a locale supported by xjdic and back later:
680
681	printf '\e]701;%s\007' ja_JP.SJIS
682	xjdic -js
683	printf '\e]701;%s\007' de_DE.UTF-8
684
685	You can also use xterm's C<luit> program, which usually works fine, except
686	for some locales where character width differs between program- and
687	rxvt-unicode-locales.
688
689	=head2 Can I switch the fonts at runtime?
690
691	Yes, using an escape sequence. Try something like this, which has the same
692	effect as using the C<-fn> switch, and takes effect immediately:
693
694	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
695
696	This is useful if you e.g. work primarily with japanese (and prefer a
697	japanese font), but you have to switch to chinese temporarily, where
698	japanese fonts would only be in your way.
699
700	You can think of this as a kind of manual ISO-2022 switching.
701
702	=head2 Why do italic characters look as if clipped?
703
704	Many fonts have difficulties with italic characters and hinting. For
705	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
706	Mono> completely fails in it's italic face. A workaround might be to
707	enable freetype autohinting, i.e. like this:
708
709	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
710	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
711
712	=head2 My input method wants <some encoding> but I want UTF-8, what can I do?
713
714	You can specify separate locales for the input method and the rest of the
715	terminal, using the resource C<imlocale>:
716
717	URxvt.imlocale: ja_JP.EUC-JP
718
719	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
720	use your input method. Please note, however, that you will not be able to
721	input characters outside C<EUC-JP> in a normal way then, as your input
722	method limits you.
723
724	=head2 Rxvt-unicode crashes when the X Input Method changes or exits.
725
726	Unfortunately, this is unavoidable, as the XIM protocol is racy by
727	design. Applications can avoid some crashes at the expense of memory
728	leaks, and Input Methods can avoid some crashes by careful ordering at
729	exit time. B<kinput2> (and derived input methods) generally succeeds,
730	while B<SCIM> (or similar input methods) fails. In the end, however,
731	crashes cannot be completely avoided even if both sides cooperate.
732
733	So the only workaround is not to kill your Input Method Servers.
734
735	=head2 Rxvt-unicode uses gobs of memory, how can I reduce that?
736
737	Rxvt-unicode tries to obey the rule of not charging you for something you
738	don't use. One thing you should try is to configure out all settings that
739	you don't need, for example, Xft support is a resource hog by design,
740	when used. Compiling it out ensures that no Xft font will be loaded
741	accidentally when rxvt-unicode tries to find a font for your characters.
742
743	Also, many people (me included) like large windows and even larger
744	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
745	6 bytes per screen cell. For a 160x?? window this amounts to almost a
746	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
747	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
748	rxvt-unicode then uses 8 bytes per screen cell.
749
750	=head2 Can I speed up Xft rendering somehow?
751
752	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
753	it is simply slow. If you still want Xft fonts you might try to disable
754	antialiasing (by appending C<:antialias=false>), which saves lots of
755	memory and also speeds up rendering considerably.
756
757	=head2 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
758
759	Rxvt-unicode will use whatever you specify as a font. If it needs to
760	fall back to it's default font search list it will prefer X11 core
761	fonts, because they are small and fast, and then use Xft fonts. It has
762	antialiasing disabled for most of them, because the author thinks they
763	look best that way.
764
765	If you want antialiasing, you have to specify the fonts manually.
766
767	=head2 Mouse cut/paste suddenly no longer works.
768
769	Make sure that mouse reporting is actually turned off since killing
770	some editors prematurely may leave the mouse in mouse report mode. I've
771	heard that tcsh may use mouse reporting unless it otherwise specified. A
772	quick check is to see if cut/paste works when the Alt or Shift keys are
773	depressed.
774
775	=head2 What's with this bold/blink stuff?
776
777	If no bold colour is set via C<colorBD:>, bold will invert text using the
778	standard foreground colour.
779
780	For the standard background colour, blinking will actually make the
781	text blink when compiled with C<--enable-blinking>. with standard
782	colours. Without C<--enable-blinking>, the blink attribute will be
783	ignored.
784
785	On ANSI colours, bold/blink attributes are used to set high-intensity
786	foreground/background colors.
787
788	color0-7 are the low-intensity colors.
789
790	color8-15 are the corresponding high-intensity colors.

792	=head2 I don't like the screen colors. How do I change them?
793
794	You can change the screen colors at run-time using F<~/.Xdefaults>
795	resources (or as long-options).
796
797	Here are values that are supposed to resemble a VGA screen,
798	including the murky brown that passes for low-intensity yellow:
799
800	URxvt.color0: #000000
801	URxvt.color1: #A80000
802	URxvt.color2: #00A800
803	URxvt.color3: #A8A800
804	URxvt.color4: #0000A8
805	URxvt.color5: #A800A8
806	URxvt.color6: #00A8A8
807	URxvt.color7: #A8A8A8
808
809	URxvt.color8: #000054
810	URxvt.color9: #FF0054
811	URxvt.color10: #00FF54
812	URxvt.color11: #FFFF54
813	URxvt.color12: #0000FF
814	URxvt.color13: #FF00FF
815	URxvt.color14: #00FFFF
816	URxvt.color15: #FFFFFF
817
818	And here is a more complete set of non-standard colors described (not by
819	me) as "pretty girly".
820
821	URxvt.cursorColor: #dc74d1
822	URxvt.pointerColor: #dc74d1
823	URxvt.background: #0e0e0e
824	URxvt.foreground: #4ad5e1
825	URxvt.color0: #000000
826	URxvt.color8: #8b8f93
827	URxvt.color1: #dc74d1
828	URxvt.color9: #dc74d1
829	URxvt.color2: #0eb8c7
830	URxvt.color10: #0eb8c7
831	URxvt.color3: #dfe37e
832	URxvt.color11: #dfe37e
833	URxvt.color5: #9e88f0
834	URxvt.color13: #9e88f0
835	URxvt.color6: #73f7ff
836	URxvt.color14: #73f7ff
837	URxvt.color7: #e1dddd
838	URxvt.color15: #e1dddd
839
840	=head2 How can I start @@RXVT_NAME@@d in a race-free way?
841
842	Try C<@@RXVT_NAME@@d -f -o>, which tells @@RXVT_NAME@@d to open the
843	display, create the listening socket and then fork.
844
845	=head2 What's with the strange Backspace/Delete key behaviour?
846
847	Assuming that the physical Backspace key corresponds to the
848	BackSpace keysym (not likely for Linux ... see the following
849	question) there are two standard values that can be used for
850	Backspace: C<^H> and C<^?>.
851
852	Historically, either value is correct, but rxvt-unicode adopts the debian
853	policy of using C<^?> when unsure, because it's the one only only correct
854	choice :).
855
856	Rxvt-unicode tries to inherit the current stty settings and uses the value
857	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
858	started from a terminal (say, from a menu or by remote shell), then the
859	system value of `erase', which corresponds to CERASE in <termios.h>, will
860	be used (which may not be the same as your stty setting).
861
862	For starting a new rxvt-unicode:
863
864	# use Backspace = ^H
865	$ stty erase ^H
866	$ @@RXVT_NAME@@
867
868	# use Backspace = ^?
869	$ stty erase ^?
870	$ @@RXVT_NAME@@
871
872	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
873
874	For an existing rxvt-unicode:
875
876	# use Backspace = ^H
877	$ stty erase ^H
878	$ echo -n "^[[36h"
879
880	# use Backspace = ^?
881	$ stty erase ^?
882	$ echo -n "^[[36l"
883
884	This helps satisfy some of the Backspace discrepancies that occur, but
885	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
886	properly reflects that.
887
888	The Delete key is a another casualty of the ill-defined Backspace problem.
889	To avoid confusion between the Backspace and Delete keys, the Delete
890	key has been assigned an escape sequence to match the vt100 for Execute
891	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
892
893	Some other Backspace problems:
894
895	some editors use termcap/terminfo,
896	some editors (vim I'm told) expect Backspace = ^H,
897	GNU Emacs (and Emacs-like editors) use ^H for help.
898
899	Perhaps someday this will all be resolved in a consistent manner.
900
901	=head2 I don't like the key-bindings. How do I change them?
902
903	There are some compile-time selections available via configure. Unless
904	you have run "configure" with the C<--disable-resources> option you can
905	use the `keysym' resource to alter the keystrings associated with keysyms.
906
907	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
908
909	URxvt.keysym.Home: \033[1~
910	URxvt.keysym.End: \033[4~
911	URxvt.keysym.C-apostrophe: \033<C-'>
912	URxvt.keysym.C-slash: \033<C-/>
913	URxvt.keysym.C-semicolon: \033<C-;>
914	URxvt.keysym.C-grave: \033<C-`>
915	URxvt.keysym.C-comma: \033<C-,>
916	URxvt.keysym.C-period: \033<C-.>
917	URxvt.keysym.C-0x60: \033<C-`>
918	URxvt.keysym.C-Tab: \033<C-Tab>
919	URxvt.keysym.C-Return: \033<C-Return>
920	URxvt.keysym.S-Return: \033<S-Return>
921	URxvt.keysym.S-space: \033<S-Space>
922	URxvt.keysym.M-Up: \033<M-Up>
923	URxvt.keysym.M-Down: \033<M-Down>
924	URxvt.keysym.M-Left: \033<M-Left>
925	URxvt.keysym.M-Right: \033<M-Right>
926	URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
927	URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
928	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
929
930	See some more examples in the documentation for the B<keysym> resource.
931
932	=head2 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 mappings that rxvt-unicode doesn't recognize.
933
934	KP_Insert == Insert
935	F22 == Print
936	F27 == Home
937	F29 == Prior
938	F33 == End
939	F35 == Next
940
941	Rather than have rxvt-unicode try to accommodate all the various possible
942	keyboard mappings, it is better to use `xmodmap' to remap the keys as
943	required for your particular machine.
944
945	=head2 How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
946
947	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
948	check and see if that is set. Note that several programs, JED, slrn,
949	Midnight Commander automatically check this variable to decide whether or
950	not to use color.
951
952	=head2 How do I set the correct, full IP address for the DISPLAY variable?
953
954	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
955	insecure mode then it is possible to use the following shell script
956	snippets to correctly set the display. If your version of rxvt-unicode
957	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
958	the COLORTERM variable can be used to distinguish rxvt-unicode from a
959	regular xterm.
960
961	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
962	snippets:
963
964	# Bourne/Korn/POSIX family of shells:
965	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
966	if [ ${TERM:-foo} = xterm ]; then
967	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
968	echo -n '^[Z'
969	read term_id
970	stty icanon echo
971	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
972	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
973	read DISPLAY # set it in our local shell
974	fi
975	fi
976
977	=head2 How do I compile the manual pages for myself?
978
979	You need to have a recent version of perl installed as F</usr/bin/perl>,
980	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
981	the doc subdirectory and enter C<make alldoc>.
982
983	=head2 My question isn't answered here, can I ask a human?
984
985	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
986	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
987	interested in learning about new and exciting problems (but not FAQs :).
