4	FREQUENTLY ASKED QUESTIONS	22	FREQUENTLY ASKED QUESTIONS
		23	The new selection selects pieces that are too big, how can I select
		24	single words?
		25	Yes. For example, if you want to select alphanumeric words, you can
		26	use the following resource:
		27
		28	URxvt.selection.pattern-0: ([[:word:]]+)
		29
		30	If you click more than twice, the selection will be extended more
		31	and more.
		32
		33	To get a selection that is very similar to the old code, try this
		34	pattern:
		35
		36	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		37
		38	Please also note that the *LeftClick Shift-LeftClik* combination
		39	also selects words like the old code.
		40
		41	I don't like the new selection/popups/hotkeys/perl, how do I
		42	change/disable it?
		43	You can disable the perl extension completely by setting the
		44	perl-ext-common resource to the empty string, which also keeps
		45	rxvt-unicode from initialising perl, saving memory.
		46
		47	If you only want to disable specific features, you first have to
		48	identify which perl extension is responsible. For this, read the
		49	section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
		50	example, to disable the selection-popup and option-popup, specify
		51	this perl-ext-common resource:
		52
		53	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		54
		55	This will keep the default extensions, but disable the two popup
		56	extensions. Some extensions can also be configured, for example,
		57	scrollback search mode is triggered by M-s. You can move it to any
		58	other combination either by setting the searchable-scrollback
		59	resource:
		60
		61	URxvt.searchable-scrollback: CM-s
		62
		63	Isn't rxvt supposed to be small? Don't all those features bloat?
		64	I often get asked about this, and I think, no, they didn't cause
		65	extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
		66	can see that the urxvt binary is larger (due to some encoding tables
		67	always being compiled in), but it actually uses less memory (RSS)
		68	after startup. Even with "--disable-everything", this comparison is
		69	a bit unfair, as many features unique to urxvt (locale, encoding
		70	conversion, iso14755 etc.) are already in use in this mode.
		71
		72	text data bss drs rss filename
		73	98398 1664 24 15695 1824 rxvt --disable-everything
		74	188985 9048 66616 18222 1788 urxvt --disable-everything
		75
		76	When you "--enable-everything" (which _is_ unfair, as this involves
		77	xft and full locale/XIM support which are quite bloaty inside libX11
		78	and my libc), the two diverge, but not unreasnobaly so.
		79
		80	text data bss drs rss filename
		81	163431 2152 24 20123 2060 rxvt --enable-everything
		82	1035683 49680 66648 29096 3680 urxvt --enable-everything
		83
		84	The very large size of the text section is explained by the
		85	east-asian encoding tables, which, if unused, take up disk space but
		86	nothing else and can be compiled out unless you rely on X11 core
		87	fonts that use those encodings. The BSS size comes from the 64k
		88	emergency buffer that my c++ compiler allocates (but of course
		89	doesn't use unless you are out of memory). Also, using an xft font
		90	instead of a core font immediately adds a few megabytes of RSS. Xft
		91	indeed is responsible for a lot of RSS even when not used.
		92
		93	Of course, due to every character using two or four bytes instead of
		94	one, a large scrollback buffer will ultimately make rxvt-unicode use
		95	more memory.
		96
		97	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
		98	this still fares rather well. And compared to some monsters like
		99	gnome-terminal (21152k + extra 4204k in separate processes) or
		100	konsole (22200k + extra 43180k in daemons that stay around after
		101	exit, plus half a minute of startup time, including the hundreds of
		102	warnings it spits out), it fares extremely well *g*.
		103
		104	Why C++, isn't that unportable/bloated/uncool?
		105	Is this a question? :) It comes up very often. The simple answer is:
		106	I had to write it, and C++ allowed me to write and maintain it in a
		107	fraction of the time and effort (which is a scarce resource for me).
		108	Put even shorter: It simply wouldn't exist without C++.
		109
		110	My personal stance on this is that C++ is less portable than C, but
		111	in the case of rxvt-unicode this hardly matters, as its portability
		112	limits are defined by things like X11, pseudo terminals, locale
		113	support and unix domain sockets, which are all less portable than
		114	C++ itself.
		115
		116	Regarding the bloat, see the above question: It's easy to write
		117	programs in C that use gobs of memory, an certainly possible to
		118	write programs in C++ that don't. C++ also often comes with large
		119	libraries, but this is not necessarily the case with GCC. Here is
		120	what rxvt links against on my system with a minimal config:
		121
		122	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		123	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		124	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		125	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		126
		127	And here is rxvt-unicode:
		128
		129	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		130	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		131	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		132	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		133	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		134
		135	No large bloated libraries (of course, none were linked in
		136	statically), except maybe libX11 :)
		137
		138	Does it support tabs, can I have a tabbed rxvt-unicode?
		139	rxvt-unicode does not directly support tabs. It will work fine with
		140	tabbing functionality of many window managers or similar tabbing
		141	programs, and its embedding-features allow it to be embedded into
		142	other programs, as witnessed by doc/rxvt-tabbed or the upcoming
		143	"Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt)
		144	terminal as an example embedding application.

		149	When using the rxvtc client, the version displayed is that of the
		150	daemon.
		151
		152	I am using Debian GNU/Linux and have a problem...
		153	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		154	patches that considerably change the behaviour of rxvt-unicode (but
		155	unfortunately this notice has been removed). Before reporting a bug
		156	to the original rxvt-unicode author please download and install the
		157	genuine version (<http://software.schmorp.de#rxvt-unicode>) and try
		158	to reproduce the problem. If you cannot, chances are that the
		159	problems are specific to Debian GNU/Linux, in which case it should
		160	be reported via the Debian Bug Tracking System (use "reportbug" to
		161	report the bug).
		162
		163	For other problems that also affect the Debian package, you can and
		164	probably should use the Debian BTS, too, because, after all, it's
		165	also a bug in the Debian version and it serves as a reminder for
		166	other users that might encounter the same issue.
		167
		168	I am maintaining rxvt-unicode for distribution/OS XXX, any
		169	recommendation?
		170	You should build one binary with the default options. configure now
		171	enables most useful options, and the trend goes to making them
		172	runtime-switchable, too, so there is usually no drawback to enbaling
		173	them, except higher disk and possibly memory usage. The perl
		174	interpreter should be enabled, as important functionality (menus,
		175	selection, likely more in the future) depends on it.
		176
		177	You should not overwrite the "perl-ext-common" snd "perl-ext"
		178	resources system-wide (except maybe with "defaults"). This will
		179	result in useful behaviour. If your distribution aims at low memory,
		180	add an empty "perl-ext-common" resource to the app-defaults file.
		181	This will keep the perl interpreter disabled until the user enables
		182	it.
		183
		184	If you can/want build more binaries, I recommend building a minimal
		185	one with "--disable-everything" (very useful) and a maximal one with
		186	"--enable-everything" (less useful, it will be very big due to a lot
		187	of encodings built-in that increase download times and are rarely
		188	used).
		189
		190	I need to make it setuid/setgid to support utmp/ptys on my OS, is this
		191	safe?
		192	It should be, starting with release 7.1. You are encouraged to
		193	properly install urxvt with privileges necessary for your OS now.
		194
		195	When rxvt-unicode detects that it runs setuid or setgid, it will
		196	fork into a helper process for privileged operations (pty handling
		197	on some systems, utmp/wtmp/lastlog handling on others) and drop
		198	privileges immediately. This is much safer than most other terminals
		199	that keep privileges while running (but is more relevant to urxvt,
		200	as it contains things as perl interpreters, which might be "helpful"
		201	to attackers).
		202
		203	This forking is done as the very first within main(), which is very
		204	early and reduces possible bugs to initialisation code run before
		205	main(), or things like the dynamic loader of your system, which
		206	should result in very little risk.

1095	menuBar
1096	The exact syntax used is *almost* solidified. In the menus, DON'T try to
1097	use menuBar commands that add or remove a menuBar.
1098
1099	Note that in all of the commands, the */path/* *cannot* be omitted: use
1100	./ to specify a menu relative to the current menu.
1101
1102	Overview of menuBar operation
1103	For the menuBar XTerm escape sequence "ESC ] 703 ; Pt ST", the syntax of
1104	"Pt" can be used for a variety of tasks:
1105
1106	At the top level is the current menuBar which is a member of a circular
1107	linked-list of other such menuBars.
1108
1109	The menuBar acts as a parent for the various drop-down menus, which in
1110	turn, may have labels, separator lines, menuItems and subMenus.
1111
1112	The menuItems are the useful bits: you can use them to mimic keyboard
1113	input or even to send text or escape sequences back to rxvt.
1114
1115	The menuBar syntax is intended to provide a simple yet robust method of
1116	constructing and manipulating menus and navigating through the menuBars.
1117
1118	The first step is to use the tag [menu:*name*] which creates the menuBar
1119	called *name* and allows access. You may now or menus, subMenus, and
1120	menuItems. Finally, use the tag [done] to set the menuBar access as
1121	readonly to prevent accidental corruption of the menus. To re-access the
1122	current menuBar for alterations, use the tag [menu], make the
1123	alterations and then use [done]
1124
1125
1126
1127	Commands
1128	[menu:+*name*]
1129	access the named menuBar for creation or alteration. If a new
1130	menuBar is created, it is called *name* (max of 15 chars) and the
1131	current menuBar is pushed onto the stack
1132
1133	[menu]
1134	access the current menuBar for alteration
1135
1136	[title:+*string*]
1137	set the current menuBar's title to *string*, which may contain the
1138	following format specifiers: %% : literal % character %n : rxvt name
1139	(as per the -name command-line option) %v : rxvt version
1140
1141	[done]
1142	set menuBar access as readonly. End-of-file tag for [read:+*file*]
1143	operations.
1144
1145	[read:+*file*]
1146	read menu commands directly from *file* (extension ".menu" will be
1147	appended if required.) Start reading at a line with [menu] or
1148	[menu:+*name* and continuing until [done] is encountered.
1149
1150	Blank and comment lines (starting with #) are ignored. Actually,
1151	since any invalid menu commands are also ignored, almost anything
1152	could be construed as a comment line, but this may be tightened up
1153	in the future ... so don't count on it!.
1154
1155	[read:+*file*;+*name*]
1156	The same as [read:+*file*], but start reading at a line with
1157	[menu:+*name*] and continuing until [done:+*name*] or [done] is
1158	encountered.
1159
1160	[dump]
1161	dump all menuBars to the file /tmp/rxvt-PID in a format suitable for
1162	later rereading.
1163
1164	[rm:name]
1165	remove the named menuBar
1166
1167	[rm] [rm:]
1168	remove the current menuBar
1169
1170	[rm*] [rm:*]
1171	remove all menuBars
1172
1173	[swap]
1174	swap the top two menuBars
1175
1176	[prev]
1177	access the previous menuBar
1178
1179	[next]
1180	access the next menuBar
1181
1182	[show]
1183	Enable display of the menuBar
1184
1185	[hide]
1186	Disable display of the menuBar
1187
1188	[pixmap:+*name*]
1189	[pixmap:+*name*;*scaling*]
1190	(set the background pixmap globally
1191
1192	A Future implementation *may* make this local to the menubar)
1193
1194	[:+*command*:]
1195	ignore the menu readonly status and issue a *command* to or a menu
1196	or menuitem or change the ; a useful shortcut for setting the quick
1197	arrows from a menuBar.

1201	Adding and accessing menus
1202	The following commands may also be + prefixed.
1203
1204	/+ access menuBar top level
1205
1206	./+ access current menu level
1207
1208	../+

1213
1214	*/path/*menu
1215	add/access menu
1216
1217	*/path/*menu/*
1218	add/access menu and clear it if it exists
1219
1220	*/path/*{-}
1221	add separator
1222
1223	*/path/*{item}
1224	add item as a label
1225
1226	*/path/*{item} action
1227	add/alter *menuitem* with an associated *action*
1228
1229	*/path/*{item}{right-text}
1230	add/alter *menuitem* with right-text as the right-justified text and
1231	as the associated *action*
1232
1233	*/path/*{item}{rtext} action
1234	add/alter *menuitem* with an associated *action* and with rtext as
1235	the right-justified text.
1236
1237	Special characters in *action* must be backslash-escaped:
1238	\a \b \E \e \n \r \t \octal
1239
1240	or in control-character notation:
1241	^@, ^A .. ^Z .. ^_, ^?
1242
1243	To send a string starting with a NUL (^@) character to the program,
1244	start *action* with a pair of NUL characters (^@^@), the first of which
1245	will be stripped off and the balance directed to the program. Otherwise
1246	if *action* begins with NUL followed by non-+NUL characters, the leading
1247	NUL is stripped off and the balance is sent back to rxvt.
1248
1249	As a convenience for the many Emacs-type editors, *action* may start
1250	with M- (eg, M-$ is equivalent to \E$) and a CR will be appended if
1251	missed from M-x commands.
1252
1253	As a convenience for issuing XTerm ESC] sequences from a menubar (or
1254	quick arrow), a BEL (^G) will be appended if needed.
1255
1256	For example,
1257	M-xapropos is equivalent to \Exapropos\r
1258
1259	and \E]703;mona;100 is equivalent to \E]703;mona;100\a
1260
1261	The option {*right-rtext*} will be right-justified. In the absence of a
1262	specified action, this text will be used as the *action* as well.
1263
1264	For example,
1265	/File/{Open}{^X^F} is equivalent to /File/{Open}{^X^F} ^X^F
1266
1267	The left label *is* necessary, since it's used for matching, but
1268	implicitly hiding the left label (by using same name for both left and
1269	right labels), or explicitly hiding the left label (by preceeding it
1270	with a dot), makes it possible to have right-justified text only.
1271
1272	For example,
1273	/File/{Open}{Open} Open-File-Action
1274
1275	or hiding it
1276	/File/{.anylabel}{Open} Open-File-Action
1277

1294	remove all items, separators and submenus from menu
1295
1296
1297
1298	Quick Arrows
1299	The menus also provide a hook for *quick arrows* to provide easier user
1300	access. If nothing has been explicitly set, the default is to emulate
1301	the curror keys. The syntax permits each arrow to be altered
1302	individually or all four at once without re-entering their common
1303	beginning/end text. For example, to explicitly associate cursor actions
1304	with the arrows, any of the following forms could be used:
1305
1306	<r>+*Right*
1307	<l>+*Left*
1308	<u>+*Up*
1309	<d>+*Down*
1310	Define actions for the respective arrow buttons
1311
1312	<b>+*Begin*
1313	<e>+*End*
1314	Define common beginning/end parts for *quick arrows* which used in
1315	conjunction with the above <r> <l> <u> <d> constructs
1316
1317	For example, define arrows individually,
1318	<u>\E[A
1319
1320	<d>\E[B
1321
1322	<r>\E[C
1323
1324	<l>\E[D
1325
1326	or all at once
1327	<u>\E[AZ<><d>\E[BZ<><r>\E[CZ<><l>\E[D
1328
1329	or more compactly (factoring out common parts)
