29=item The new selection selects pieces that are too big, how can I select
30single words?
31
32Yes. For example, if you want to select alphanumeric words, you can use
33the following resource:
34
35 URxvt.selection.pattern-0: ([[:word:]]+)
36
37If you click more than twice, the selection will be extended
38more and more.
39
40To get a selection that is very similar to the old code, try this pattern:
41
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
43
44Please also note that the I<LeftClick Shift-LeftClik> combination also
45selects words like the old code.
46
47=item I don't like the new selection/popups/hotkeys/perl, how do I
48change/disable it?
49
50You can disable the perl extension completely by setting the
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53
54If you only want to disable specific features, you first have to
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup
61
62This will keep the default extensions, but disable the two popup
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other 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
71I often get asked about this, and I think, no, they didn't cause extra
72bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
73that the urxvt binary is larger (due to some encoding tables always being
74compiled in), but it actually uses less memory (RSS) after startup. Even
75with C<--disable-everything>, this comparison is a bit unfair, as many
76features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
77already 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
83When you C<--enable-everything> (which _is_ unfair, as this involves xft
84and full locale/XIM support which are quite bloaty inside libX11 and my
85libc), 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
91The very large size of the text section is explained by the east-asian
92encoding tables, which, if unused, take up disk space but nothing else
93and can be compiled out unless you rely on X11 core fonts that use those
94encodings. The BSS size comes from the 64k emergency buffer that my c++
95compiler allocates (but of course doesn't use unless you are out of
96memory). Also, using an xft font instead of a core font immediately adds a
97few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
98not used.
99
100Of course, due to every character using two or four bytes instead of one,
101a large scrollback buffer will ultimately make rxvt-unicode use more
102memory.
103
104Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
105still fares rather well. And compared to some monsters like gnome-terminal
106(21152k + extra 4204k in separate processes) or konsole (22200k + extra
10743180k in daemons that stay around after exit, plus half a minute of
108startup time, including the hundreds of warnings it spits out), it fares
109extremely well *g*.
110
111=item Why C++, isn't that unportable/bloated/uncool?
112
113Is this a question? :) It comes up very often. The simple answer is: I had
114to write it, and C++ allowed me to write and maintain it in a fraction
115of the time and effort (which is a scarce resource for me). Put even
116shorter: It simply wouldn't exist without C++.
117
118My personal stance on this is that C++ is less portable than C, but in
119the case of rxvt-unicode this hardly matters, as its portability limits
120are defined by things like X11, pseudo terminals, locale support and unix
121domain sockets, which are all less portable than C++ itself.
122
123Regarding the bloat, see the above question: It's easy to write programs
124in C that use gobs of memory, an certainly possible to write programs in
125C++ that don't. C++ also often comes with large libraries, but this is
126not necessarily the case with GCC. Here is what rxvt links against on my
127system 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
134And 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
142No large bloated libraries (of course, none were linked in statically),
143except maybe libX11 :)
144
145=item Does it support tabs, can I have a tabbed rxvt-unicode?
146
147rxvt-unicode does not directly support tabs. It will work fine with
148tabbing functionality of many window managers or similar tabbing programs,
149and its embedding-features allow it to be embedded into other programs,
150as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
151module, which features a tabbed urxvt (murxvt) terminal as an example
152embedding application.

48might encounter the same issue. 175might encounter the same issue.
176
177=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
178
179You should build one binary with the default options. F<configure>
180now enables most useful options, and the trend goes to making them
181runtime-switchable, too, so there is usually no drawback to enbaling them,
182except higher disk and possibly memory usage. The perl interpreter should
183be enabled, as important functionality (menus, selection, likely more in
184the future) depends on it.
185
186You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
187system-wide (except maybe with C<defaults>). This will result in useful
188behaviour. If your distribution aims at low memory, add an empty
189C<perl-ext-common> resource to the app-defaults file. This will keep the
190perl interpreter disabled until the user enables it.
191
192If you can/want build more binaries, I recommend building a minimal
193one with C<--disable-everything> (very useful) and a maximal one with
194C<--enable-everything> (less useful, it will be very big due to a lot of
195encodings 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
199Likely not. While I honestly try to make it secure, and am probably not
200bad at it, I think it is simply unreasonable to expect all of freetype
201+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202secure. Also, rxvt-unicode disables some options when it detects that it
203runs setuid or setgid, which is not nice. Besides, with the embedded perl
204interpreter the possibility for security problems easily multiplies.
205
206Elevated privileges are only required for utmp and pty operations on some
207systems (for example, GNU/Linux doesn't need any extra privileges for
208ptys, but some need it for utmp support). It is planned to mvoe this into
209a forked handler process, but this is not yet done.
210
211So, while setuid/setgid operation is supported and not a problem on your
212typical single-user-no-other-logins unix desktop, always remember that
213its an awful lot of code, most of which isn't checked for security issues
214regularly.
