29=item I don't like the new selection/popups/hotkeys/perl, how do I
30change/disable it?
31
32You can disable the perl extension completely by setting the
33B<perl-ext-common> resource to the empty string, which also keeps
34rxvt-unicode from initialising perl, saving memory.
35
36If you only want to disable specific features, you first have to
37identify which perl extension is responsible. For this, read the section
38B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
39example, to disable the B<selection-popup> and B<option-popup>, specify
40this B<perl-ext-common> resource:
41
42 URxvt.perl-ext-common: default,-selection-popup,-option-popup
43
44This will keep the default extensions, but disable the two popup
45extensions. Some extensions can also be configured, for example,
46scrollback search mode is triggered by B<M-s>. You can move it to any
47other combination either by setting the B<searchable-scrollback> resource:
48
49 URxvt.searchable-scrollback: CM-s
50
51=item Isn't rxvt supposed to be small? Don't all those features bloat?
52
53I often get asked about this, and I think, no, they didn't cause extra
54bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
55that the urxvt binary is larger (due to some encoding tables always being
56compiled in), but it actually uses less memory (RSS) after startup. Even
57with C<--disable-everything>, this comparison is a bit unfair, as many
58features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
59already in use in this mode.
60

62 98398 1664 24 15695 1824 rxvt --disable-everything
63 188985 9048 66616 18222 1788 urxvt --disable-everything
64
65When you C<--enable-everything> (which _is_ unfair, as this involves xft
66and full locale/XIM support which are quite bloaty inside libX11 and my
67libc), the two diverge, but not unreasnobaly so.
68
69 text data bss drs rss filename
70 163431 2152 24 20123 2060 rxvt --enable-everything
71 1035683 49680 66648 29096 3680 urxvt --enable-everything
72
73The very large size of the text section is explained by the east-asian
74encoding tables, which, if unused, take up disk space but nothing else
75and can be compiled out unless you rely on X11 core fonts that use those
76encodings. The BSS size comes from the 64k emergency buffer that my c++
77compiler allocates (but of course doesn't use unless you are out of
78memory). Also, using an xft font instead of a core font immediately adds a
79few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
80not used.
81
82Of course, due to every character using two or four bytes instead of one,
83a large scrollback buffer will ultimately make rxvt-unicode use more
84memory.
85
86Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
87still fares rather well. And compared to some monsters like gnome-terminal
88(21152k + extra 4204k in separate processes) or konsole (22200k + extra
8943180k in daemons that stay around after exit, plus half a minute of
90startup time, including the hundreds of warnings it spits out), it fares
91extremely well *g*.
92
93=item Why C++, isn't that unportable/bloated/uncool?
94
95Is this a question? :) It comes up very often. The simple answer is: I had
96to write it, and C++ allowed me to write and maintain it in a fraction
97of the time and effort (which is a scarce resource for me). Put even
98shorter: It simply wouldn't exist without C++.
99
100My personal stance on this is that C++ is less portable than C, but in
101the case of rxvt-unicode this hardly matters, as its portability limits
102are defined by things like X11, pseudo terminals, locale support and unix
103domain sockets, which are all less portable than C++ itself.
104
105Regarding the bloat, see the above question: It's easy to write programs
106in C that use gobs of memory, an certainly possible to write programs in
107C++ that don't. C++ also often comes with large libraries, but this is
108not necessarily the case with GCC. Here is what rxvt links against on my
109system with a minimal config:
110
111 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
112 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
113 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
114 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
115
116And here is rxvt-unicode:
117
118 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
119 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
120 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
121 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
122 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
123
124No large bloated libraries (of course, none were linked in statically),
125except maybe libX11 :)
126
127=item Does it support tabs, can I have a tabbed rxvt-unicode?
128
129rxvt-unicode does not directly support tabs. It will work fine with
130tabbing functionality of many window managers or similar tabbing programs,
131and its embedding-features allow it to be embedded into other programs,
132as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
133module, which features a tabbed urxvt (murxvt) terminal as an example
134embedding application.

48might encounter the same issue. 157might encounter the same issue.
158
159=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
160
161You should build one binary with the default options. F<configure>
162now enables most useful options, and the trend goes to making them
163runtime-switchable, too, so there is usually no drawback to enbaling them,
164except higher disk and possibly memory usage. The perl interpreter should
165be enabled, as important functionality (menus, selection, likely more in
166the future) depends on it.
167
168You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
169system-wide (except maybe with C<defaults>). This will result in useful
170behaviour. If your distribution aims at low memory, add an empty
171C<perl-ext-common> resource to the app-defaults file. This will keep the
172perl interpreter disabled until the user enables it.
173
174If you can/want build more binaries, I recommend building a minimal
175one with C<--disable-everything> (very useful) and a maximal one with
176C<--enable-everything> (less useful, it will be very big due to a lot of
177encodings built-in that increase download times and are rarely used).
178
179=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
180
181Likely not. While I honestly try to make it secure, and am probably not
182bad at it, I think it is simply unreasonable to expect all of freetype
183+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
184secure. Also, rxvt-unicode disables some options when it detects that it
185runs setuid or setgid, which is not nice. Besides, with the embedded perl
186interpreter the possibility for security problems easily multiplies.
187
188Elevated privileges are only required for utmp and pty operations on some
189systems (for example, GNU/Linux doesn't need any extra privileges for
190ptys, but some need it for utmp support). It is planned to mvoe this into
191a forked handler process, but this is not yet done.
192
193So, while setuid/setgid operation is supported and not a problem on your
194typical single-user-no-other-logins unix desktop, always remember that
195its an awful lot of code, most of which isn't checked for security issues
196regularly.
