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

148
149 I am maintaining rxvt-unicode for distribution/OS XXX, any
150 recommendation?
151 You should build one binary with the default options. configure now
152 enables most useful options, and the trend goes to making them
153 runtime-switchable, too, so there is usually no drawback to enbaling
154 them, except higher disk and possibly memory usage. The perl
155 interpreter should be enabled, as important functionality (menus,
156 selection, likely more in the future) depends on it.
157
158 You should not overwrite the "perl-ext-common" snd "perl-ext"
159 resources system-wide (except maybe with "defaults"). This will
160 result in useful behaviour. If your distribution aims at low memory,
161 add an empty "perl-ext-common" resource to the app-defaults file.
162 This will keep the perl interpreter disabled until the user enables
163 it.
164
165 If you can/want build more binaries, I recommend building a minimal
166 one with "--disable-everything" (very useful) and a maximal one with
167 "--enable-everything" (less useful, it will be very big due to a lot
168 of encodings built-in that increase download times and are rarely
169 used).
170
171 I need to make it setuid/setgid to support utmp/ptys on my OS, is this
172 safe?
173 Likely not. While I honestly try to make it secure, and am probably
174 not bad at it, I think it is simply unreasonable to expect all of
175 freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
176 itself to all be secure. Also, rxvt-unicode disables some options
177 when it detects that it runs setuid or setgid, which is not nice.
178 Besides, with the embedded perl interpreter the possibility for
179 security problems easily multiplies.
180
181 Elevated privileges are only required for utmp and pty operations on
182 some systems (for example, GNU/Linux doesn't need any extra
183 privileges for ptys, but some need it for utmp support). It is
184 planned to mvoe this into a forked handler process, but this is not
185 yet done.
186
187 So, while setuid/setgid operation is supported and not a problem on
188 your typical single-user-no-other-logins unix desktop, always
189 remember that its an awful lot of code, most of which isn't checked
190 for security issues regularly.
