29=item The new selection selects pieces that are too big/too small, can I
30change this?
31
32Yes. For example, if you want to select smaller pieces ("words") you can
33use the 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
44=item I don't like the new selection/popups/hotkeys/perl, how do I
45change/disable it?
46
47You can disable the perl extension completely by setting the
48B<perl-ext-common> resource to the empty string, which also keeps
49rxvt-unicode from initialising perl, saving memory.
50
51If you only want to disable specific features, you first have to
52identify which perl extension is responsible. For this, read the section
53B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
54example, to disable the B<selection-popup> and B<option-popup>, specify
55this B<perl-ext-common> resource:
56
57 URxvt.perl-ext-common: default,-selection-popup,-option-popup
58
59This will keep the default extensions, but disable the two popup
60extensions. Some extensions can also be configured, for example,
61scrollback search mode is triggered by B<M-s>. You can move it to any
62other combination either by setting the B<searchable-scrollback> resource:
63
64 URxvt.searchable-scrollback: CM-s

135might encounter the same issue. 172might encounter the same issue.
173
174=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
175
176You should build one binary with the default options. F<configure>
177now enables most useful options, and the trend goes to making them
178runtime-switchable, too, so there is usually no drawback to enbaling them,
179except higher disk and possibly memory usage. The perl interpreter should
180be enabled, as important functionality (menus, selection, likely more in
181the future) depends on it.
182
183You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
184system-wide (except maybe with C<defaults>). This will result in useful
185behaviour. If your distribution aims at low memory, add an empty
186C<perl-ext-common> resource to the app-defaults file. This will keep the
187perl interpreter disabled until the user enables it.
188
189If you can/want build more binaries, I recommend building a minimal
190one with C<--disable-everything> (very useful) and a maximal one with
191C<--enable-everything> (less useful, it will be very big due to a lot of
192encodings built-in that increase download times and are rarely used).
193
194=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
195
196Likely not. While I honestly try to make it secure, and am probably not
197bad at it, I think it is simply unreasonable to expect all of freetype
198+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
199secure. Also, rxvt-unicode disables some options when it detects that it
200runs setuid or setgid, which is not nice. Besides, with the embedded perl
201interpreter the possibility for security problems easily multiplies.
202
203Elevated privileges are only required for utmp and pty operations on some
204systems (for example, GNU/Linux doesn't need any extra privileges for
205ptys, but some need it for utmp support). It is planned to mvoe this into
206a forked handler process, but this is not yet done.
207
208So, while setuid/setgid operation is supported and not a problem on your
209typical single-user-no-other-logins unix desktop, always remember that
210its an awful lot of code, most of which isn't checked for security issues
211regularly.
