		29	=item The new selection selects pieces that are too big, how can I select
		30	single words?
		31
		32	Yes. For example, if you want to select alphanumeric words, you can use
		33	the following resource:
		34
		35	URxvt.selection.pattern-0: ([[:word:]]+)
		36
		37	If you click more than twice, the selection will be extended
		38	more and more.
		39
		40	To get a selection that is very similar to the old code, try this pattern:
		41
		42	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{\|})]+)
		43
		44	Please also note that the I<LeftClick Shift-LeftClik> combination also
		45	selects words like the old code.
		46
		47	=item I don't like the new selection/popups/hotkeys/perl, how do I
		48	change/disable it?
		49
		50	You can disable the perl extension completely by setting the
		51	B<perl-ext-common> resource to the empty string, which also keeps
		52	rxvt-unicode from initialising perl, saving memory.
		53
		54	If you only want to disable specific features, you first have to
		55	identify which perl extension is responsible. For this, read the section
		56	B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
		57	example, to disable the B<selection-popup> and B<option-popup>, specify
		58	this B<perl-ext-common> resource:
		59
		60	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		61
		62	This will keep the default extensions, but disable the two popup
		63	extensions. Some extensions can also be configured, for example,
		64	scrollback search mode is triggered by B<M-s>. You can move it to any
		65	other combination either by setting the B<searchable-scrollback> resource:
		66
		67	URxvt.searchable-scrollback: CM-s
		68
		69	=item Isn't rxvt supposed to be small? Don't all those features bloat?
		70
		71	I often get asked about this, and I think, no, they didn't cause extra
		72	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		73	that the urxvt binary is larger (due to some encoding tables always being
		74	compiled in), but it actually uses less memory (RSS) after startup. Even
		75	with C<--disable-everything>, this comparison is a bit unfair, as many
		76	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		77	already in use in this mode.
		78
		79	text data bss drs rss filename
		80	98398 1664 24 15695 1824 rxvt --disable-everything
		81	188985 9048 66616 18222 1788 urxvt --disable-everything
		82
		83	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		84	and full locale/XIM support which are quite bloaty inside libX11 and my
		85	libc), the two diverge, but not unreasnobaly so.
		86
		87	text data bss drs rss filename
		88	163431 2152 24 20123 2060 rxvt --enable-everything
		89	1035683 49680 66648 29096 3680 urxvt --enable-everything
		90
		91	The very large size of the text section is explained by the east-asian
		92	encoding tables, which, if unused, take up disk space but nothing else
		93	and can be compiled out unless you rely on X11 core fonts that use those
		94	encodings. The BSS size comes from the 64k emergency buffer that my c++
		95	compiler allocates (but of course doesn't use unless you are out of
		96	memory). Also, using an xft font instead of a core font immediately adds a
		97	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		98	not used.
		99
		100	Of course, due to every character using two or four bytes instead of one,
		101	a large scrollback buffer will ultimately make rxvt-unicode use more
		102	memory.
		103
		104	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		105	still fares rather well. And compared to some monsters like gnome-terminal
		106	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		107	43180k in daemons that stay around after exit, plus half a minute of
		108	startup time, including the hundreds of warnings it spits out), it fares
		109	extremely well g.
		110
		111	=item Why C++, isn't that unportable/bloated/uncool?
		112
		113	Is this a question? :) It comes up very often. The simple answer is: I had
		114	to write it, and C++ allowed me to write and maintain it in a fraction
		115	of the time and effort (which is a scarce resource for me). Put even
		116	shorter: It simply wouldn't exist without C++.
		117
		118	My personal stance on this is that C++ is less portable than C, but in
		119	the case of rxvt-unicode this hardly matters, as its portability limits
		120	are defined by things like X11, pseudo terminals, locale support and unix
		121	domain sockets, which are all less portable than C++ itself.
		122
		123	Regarding the bloat, see the above question: It's easy to write programs
		124	in C that use gobs of memory, an certainly possible to write programs in
		125	C++ that don't. C++ also often comes with large libraries, but this is
		126	not necessarily the case with GCC. Here is what rxvt links against on my
		127	system with a minimal config:
		128
		129	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		130	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		131	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		132	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		133
		134	And here is rxvt-unicode:
		135
		136	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		137	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		138	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		139	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		140	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		141
		142	No large bloated libraries (of course, none were linked in statically),
		143	except maybe libX11 :)
		144
		145	=item Does it support tabs, can I have a tabbed rxvt-unicode?
		146
		147	rxvt-unicode does not directly support tabs. It will work fine with
		148	tabbing functionality of many window managers or similar tabbing programs,
		149	and its embedding-features allow it to be embedded into other programs,
		150	as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
		151	module, which features a tabbed urxvt (murxvt) terminal as an example
		152	embedding application.

		159	daemon.
		160
		161	=item I am using Debian GNU/Linux and have a problem...
		162
		163	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		164	patches that considerably change the behaviour of rxvt-unicode. Before
		165	reporting a bug to the original rxvt-unicode author please download and
		166	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
		167	and try to reproduce the problem. If you cannot, chances are that the
		168	problems are specific to Debian GNU/Linux, in which case it should be
		169	reported via the Debian Bug Tracking System (use C<reportbug> to report
		170	the bug).
		171
		172	For other problems that also affect the Debian package, you can and
		173	probably should use the Debian BTS, too, because, after all, it's also a
		174	bug in the Debian version and it serves as a reminder for other users that
		175	might encounter the same issue.
		176
		177	=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		178
		179	You should build one binary with the default options. F<configure>
		180	now enables most useful options, and the trend goes to making them
		181	runtime-switchable, too, so there is usually no drawback to enbaling them,
		182	except higher disk and possibly memory usage. The perl interpreter should
		183	be enabled, as important functionality (menus, selection, likely more in
		184	the future) depends on it.
		185
		186	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		187	system-wide (except maybe with C<defaults>). This will result in useful
		188	behaviour. If your distribution aims at low memory, add an empty
		189	C<perl-ext-common> resource to the app-defaults file. This will keep the
		190	perl interpreter disabled until the user enables it.
		191
		192	If you can/want build more binaries, I recommend building a minimal
		193	one with C<--disable-everything> (very useful) and a maximal one with
		194	C<--enable-everything> (less useful, it will be very big due to a lot of
		195	encodings built-in that increase download times and are rarely used).
		196
		197	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		198
		199	Likely not. While I honestly try to make it secure, and am probably not
		200	bad at it, I think it is simply unreasonable to expect all of freetype
		201	+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
		202	secure. Also, rxvt-unicode disables some options when it detects that it
		203	runs setuid or setgid, which is not nice. Besides, with the embedded perl
		204	interpreter the possibility for security problems easily multiplies.
		205
		206	Elevated privileges are only required for utmp and pty operations on some
		207	systems (for example, GNU/Linux doesn't need any extra privileges for
		208	ptys, but some need it for utmp support). It is planned to mvoe this into
		209	a forked handler process, but this is not yet done.
		210
		211	So, while setuid/setgid operation is supported and not a problem on your
		212	typical single-user-no-other-logins unix desktop, always remember that
		213	its an awful lot of code, most of which isn't checked for security issues
		214	regularly.
