4FREQUENTLY ASKED QUESTIONS 22FREQUENTLY ASKED QUESTIONS
23 The new selection selects pieces that are too big/too small, can I
24 change this?
25 Yes. For example, if you want to select smaller pieces ("words") you
26 can 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 I don't like the new selection/popups/hotkeys/perl, how do I
39 change/disable it?
40 You can disable the perl extension completely by setting the
41 perl-ext-common resource to the empty string, which also keeps
42 rxvt-unicode from initialising perl, saving memory.
43
44 If you only want to disable specific features, you first have to
45 identify which perl extension is responsible. For this, read the
46 section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
47 example, to disable the selection-popup and option-popup, specify
48 this perl-ext-common resource:
49
50 URxvt.perl-ext-common: default,-selection-popup,-option-popup
51
52 This will keep the default extensions, but disable the two popup
53 extensions. Some extensions can also be configured, for example,
54 scrollback search mode is triggered by M-s. You can move it to any
55 other combination either by setting the searchable-scrollback
56 resource:
57
58 URxvt.searchable-scrollback: CM-s
59
60 Isn't rxvt supposed to be small? Don't all those features bloat?
61 I often get asked about this, and I think, no, they didn't cause
62 extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
63 can see that the urxvt binary is larger (due to some encoding tables
64 always being compiled in), but it actually uses less memory (RSS)
65 after startup. Even with "--disable-everything", this comparison is
66 a bit unfair, as many features unique to urxvt (locale, encoding
67 conversion, iso14755 etc.) are already in use in this mode.
68
69 text data bss drs rss filename
70 98398 1664 24 15695 1824 rxvt --disable-everything
71 188985 9048 66616 18222 1788 urxvt --disable-everything
72
73 When you "--enable-everything" (which _is_ unfair, as this involves
74 xft and full locale/XIM support which are quite bloaty inside libX11
75 and my libc), the two diverge, but not unreasnobaly so.
76
77 text data bss drs rss filename
78 163431 2152 24 20123 2060 rxvt --enable-everything
79 1035683 49680 66648 29096 3680 urxvt --enable-everything
80
81 The very large size of the text section is explained by the
82 east-asian encoding tables, which, if unused, take up disk space but
83 nothing else and can be compiled out unless you rely on X11 core
84 fonts that use those encodings. The BSS size comes from the 64k
85 emergency buffer that my c++ compiler allocates (but of course
86 doesn't use unless you are out of memory). Also, using an xft font
87 instead of a core font immediately adds a few megabytes of RSS. Xft
88 indeed is responsible for a lot of RSS even when not used.
89
90 Of course, due to every character using two or four bytes instead of
91 one, a large scrollback buffer will ultimately make rxvt-unicode use
92 more memory.
93
94 Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
95 this still fares rather well. And compared to some monsters like
96 gnome-terminal (21152k + extra 4204k in separate processes) or
97 konsole (22200k + extra 43180k in daemons that stay around after
98 exit, plus half a minute of startup time, including the hundreds of
99 warnings it spits out), it fares extremely well *g*.
100
101 Why C++, isn't that unportable/bloated/uncool?
102 Is this a question? :) It comes up very often. The simple answer is:
103 I had to write it, and C++ allowed me to write and maintain it in a
104 fraction of the time and effort (which is a scarce resource for me).
105 Put even shorter: It simply wouldn't exist without C++.
106
107 My personal stance on this is that C++ is less portable than C, but
108 in the case of rxvt-unicode this hardly matters, as its portability
109 limits are defined by things like X11, pseudo terminals, locale
110 support and unix domain sockets, which are all less portable than
111 C++ itself.
112
113 Regarding the bloat, see the above question: It's easy to write
114 programs in C that use gobs of memory, an certainly possible to
115 write programs in C++ that don't. C++ also often comes with large
116 libraries, but this is not necessarily the case with GCC. Here is
117 what rxvt links against on my system with a minimal config:
118
119 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
120 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
121 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
122 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
123
124 And here is rxvt-unicode:
125
126 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
127 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
128 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
129 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
130 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
131
132 No large bloated libraries (of course, none were linked in
133 statically), except maybe libX11 :)
134
135 Does it support tabs, can I have a tabbed rxvt-unicode?
136 rxvt-unicode does not directly support tabs. It will work fine with
137 tabbing functionality of many window managers or similar tabbing
138 programs, and its embedding-features allow it to be embedded into
139 other programs, as witnessed by doc/rxvt-tabbed or the upcoming
140 "Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt)
141 terminal as an example embedding application.
142
5 How do I know which rxvt-unicode version I'm using? 143 How do I know which rxvt-unicode version I'm using?
6 The version number is displayed with the usage (-h). Also the escape 144 The version number is displayed with the usage (-h). Also the escape
7 sequence "ESC[8n" sets the window title to the version number. 145 sequence "ESC [ 8 n" sets the window title to the version number.
146 When using the rxvtc client, the version displayed is that of the
147 daemon.
148
149 I am using Debian GNU/Linux and have a problem...
150 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
151 patches that considerably change the behaviour of rxvt-unicode.
152 Before reporting a bug to the original rxvt-unicode author please
153 download and install the genuine version
154 (<http://software.schmorp.de#rxvt-unicode>) and try to reproduce the
155 problem. If you cannot, chances are that the problems are specific
156 to Debian GNU/Linux, in which case it should be reported via the
157 Debian Bug Tracking System (use "reportbug" to report the bug).
158
159 For other problems that also affect the Debian package, you can and
160 probably should use the Debian BTS, too, because, after all, it's
161 also a bug in the Debian version and it serves as a reminder for
162 other users that might encounter the same issue.
163
164 I am maintaining rxvt-unicode for distribution/OS XXX, any
165 recommendation?
166 You should build one binary with the default options. configure now
167 enables most useful options, and the trend goes to making them
168 runtime-switchable, too, so there is usually no drawback to enbaling
169 them, except higher disk and possibly memory usage. The perl
170 interpreter should be enabled, as important functionality (menus,
171 selection, likely more in the future) depends on it.
172
173 You should not overwrite the "perl-ext-common" snd "perl-ext"
174 resources system-wide (except maybe with "defaults"). This will
175 result in useful behaviour. If your distribution aims at low memory,
176 add an empty "perl-ext-common" resource to the app-defaults file.
177 This will keep the perl interpreter disabled until the user enables
178 it.
179
180 If you can/want build more binaries, I recommend building a minimal
181 one with "--disable-everything" (very useful) and a maximal one with
182 "--enable-everything" (less useful, it will be very big due to a lot
183 of encodings built-in that increase download times and are rarely
184 used).
185
186 I need to make it setuid/setgid to support utmp/ptys on my OS, is this
187 safe?
188 Likely not. While I honestly try to make it secure, and am probably
189 not bad at it, I think it is simply unreasonable to expect all of
190 freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
191 itself to all be secure. Also, rxvt-unicode disables some options
192 when it detects that it runs setuid or setgid, which is not nice.
193 Besides, with the embedded perl interpreter the possibility for
194 security problems easily multiplies.
195
196 Elevated privileges are only required for utmp and pty operations on
197 some systems (for example, GNU/Linux doesn't need any extra
198 privileges for ptys, but some need it for utmp support). It is
199 planned to mvoe this into a forked handler process, but this is not
200 yet done.
201
202 So, while setuid/setgid operation is supported and not a problem on
203 your typical single-user-no-other-logins unix desktop, always
204 remember that its an awful lot of code, most of which isn't checked
205 for security issues regularly.

10 The terminal description used by rxvt-unicode is not as widely 208 The terminal description used by rxvt-unicode is not as widely
11 available as that for xterm, or even rxvt (for which the same 209 available as that for xterm, or even rxvt (for which the same

33 232
34 If you don't plan to use rxvt (quite common...) you could also 233 If you don't plan to use rxvt (quite common...) you could also
35 replace the rxvt terminfo file with the rxvt-unicode one. 234 replace the rxvt terminfo file with the rxvt-unicode one.
36 235
236 "tic" outputs some error when compiling the terminfo entry.
237 Most likely it's the empty definition for "enacs=". Just replace it
238 by "enacs=\E[0@" and try again.
239
240 "bash"'s readline does not work correctly under rxvt.
37 I need a termcap file entry. 241 I need a termcap file entry.
242 One reason you might want this is that some distributions or
243 operating systems still compile some programs using the
244 long-obsoleted termcap library (Fedora Core's bash is one example)
245 and rely on a termcap entry for "rxvt-unicode".
246
38 You could use rxvt's termcap entry with resonable results in many 247 You could use rxvt's termcap entry with resonable results in many

508 rxvt-unicode should compile and run out of the box on cygwin, using

510 longer supported (and makes no sense, either, as it only supported a
511 single font). I recommend starting the X-server in "-multiwindow" or
512 "-rootless" mode instead, which will result in similar look&feel as
513 the old libW11 emulation.
514
515 At the time of this writing, cygwin didn't seem to support any
516 multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are
