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.
145

24 The version number is displayed with the usage (-h). Also the escape 147 The version number is displayed with the usage (-h). Also the escape
25 sequence "ESC [ 8 n" sets the window title to the version number. 148 sequence "ESC [ 8 n" sets the window title to the version number.

166
167 I am maintaining rxvt-unicode for distribution/OS XXX, any
168 recommendation?
169 You should build one binary with the default options. configure now
170 enables most useful options, and the trend goes to making them
171 runtime-switchable, too, so there is usually no drawback to enbaling
172 them, except higher disk and possibly memory usage. The perl
173 interpreter should be enabled, as important functionality (menus,
174 selection, likely more in the future) depends on it.
175
176 You should not overwrite the "perl-ext-common" snd "perl-ext"
177 resources system-wide (except maybe with "defaults"). This will
178 result in useful behaviour. If your distribution aims at low memory,
179 add an empty "perl-ext-common" resource to the app-defaults file.
180 This will keep the perl interpreter disabled until the user enables
181 it.
182
183 If you can/want build more binaries, I recommend building a minimal
184 one with "--disable-everything" (very useful) and a maximal one with
185 "--enable-everything" (less useful, it will be very big due to a lot
186 of encodings built-in that increase download times and are rarely
187 used).
188
189 I need to make it setuid/setgid to support utmp/ptys on my OS, is this
190 safe?
191 Likely not. While I honestly try to make it secure, and am probably
192 not bad at it, I think it is simply unreasonable to expect all of
193 freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
194 itself to all be secure. Also, rxvt-unicode disables some options
195 when it detects that it runs setuid or setgid, which is not nice.
196 Besides, with the embedded perl interpreter the possibility for
197 security problems easily multiplies.
198
199 Elevated privileges are only required for utmp and pty operations on
200 some systems (for example, GNU/Linux doesn't need any extra
201 privileges for ptys, but some need it for utmp support). It is
202 planned to mvoe this into a forked handler process, but this is not
203 yet done.
204
205 So, while setuid/setgid operation is supported and not a problem on
206 your typical single-user-no-other-logins unix desktop, always
207 remember that its an awful lot of code, most of which isn't checked
208 for security issues regularly.
