29=item The new selection selects pieces that are too big, how can I select
30single words?
31
32Yes. For example, if you want to select alphanumeric words, you can use
33the 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
44Please also note that the I<LeftClick Shift-LeftClik> combination also
45selects words like the old code.
46
47=item I don't like the new selection/popups/hotkeys/perl, how do I
48change/disable it?
49
50You can disable the perl extension completely by setting the
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53
54If you only want to disable specific features, you first have to
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup
61
62This will keep the default extensions, but disable the two popup
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other combination either by setting the B<searchable-scrollback> resource:
66
67 URxvt.searchable-scrollback: CM-s

176
177=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
178
179You should build one binary with the default options. F<configure>
180now enables most useful options, and the trend goes to making them
181runtime-switchable, too, so there is usually no drawback to enbaling them,
182except higher disk and possibly memory usage. The perl interpreter should
183be enabled, as important functionality (menus, selection, likely more in
184the future) depends on it.
185
186You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
187system-wide (except maybe with C<defaults>). This will result in useful
188behaviour. If your distribution aims at low memory, add an empty
189C<perl-ext-common> resource to the app-defaults file. This will keep the
190perl interpreter disabled until the user enables it.
191
192If you can/want build more binaries, I recommend building a minimal
193one with C<--disable-everything> (very useful) and a maximal one with
194C<--enable-everything> (less useful, it will be very big due to a lot of
195encodings built-in that increase download times and are rarely used).
196
197=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
198
199Likely not. While I honestly try to make it secure, and am probably not
200bad at it, I think it is simply unreasonable to expect all of freetype
201+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202secure. Also, rxvt-unicode disables some options when it detects that it
203runs setuid or setgid, which is not nice. Besides, with the embedded perl
204interpreter the possibility for security problems easily multiplies.
205
206Elevated privileges are only required for utmp and pty operations on some
207systems (for example, GNU/Linux doesn't need any extra privileges for
208ptys, but some need it for utmp support). It is planned to mvoe this into
209a forked handler process, but this is not yet done.
210
211So, while setuid/setgid operation is supported and not a problem on your
212typical single-user-no-other-logins unix desktop, always remember that
213its an awful lot of code, most of which isn't checked for security issues
214regularly.
