2 The new selection selects pieces that are too big, how can I select
3 single words?
4 Yes. For example, if you want to select alphanumeric words, you can
5 use the following resource:
6
7 URxvt.selection.pattern-0: ([[:word:]]+)
8
9 If you click more than twice, the selection will be extended more
10 and more.
11
12 To get a selection that is very similar to the old code, try this
13 pattern:
14
15 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
16
17 Please also note that the *LeftClick Shift-LeftClik* combination
18 also selects words like the old code.
19
20 I don't like the new selection/popups/hotkeys/perl, how do I
21 change/disable it?
22 You can disable the perl extension completely by setting the
23 perl-ext-common resource to the empty string, which also keeps
24 rxvt-unicode from initialising perl, saving memory.
25
26 If you only want to disable specific features, you first have to
27 identify which perl extension is responsible. For this, read the
28 section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
29 example, to disable the selection-popup and option-popup, specify
30 this perl-ext-common resource:
31
32 URxvt.perl-ext-common: default,-selection-popup,-option-popup
33
34 This will keep the default extensions, but disable the two popup
35 extensions. Some extensions can also be configured, for example,
36 scrollback search mode is triggered by M-s. You can move it to any
37 other combination either by setting the searchable-scrollback
38 resource:
39
40 URxvt.searchable-scrollback: CM-s

105 145
146 I am maintaining rxvt-unicode for distribution/OS XXX, any
147 recommendation?
148 You should build one binary with the default options. configure now
149 enables most useful options, and the trend goes to making them
150 runtime-switchable, too, so there is usually no drawback to enbaling
151 them, except higher disk and possibly memory usage. The perl
152 interpreter should be enabled, as important functionality (menus,
153 selection, likely more in the future) depends on it.
154
155 You should not overwrite the "perl-ext-common" snd "perl-ext"
156 resources system-wide (except maybe with "defaults"). This will
157 result in useful behaviour. If your distribution aims at low memory,
158 add an empty "perl-ext-common" resource to the app-defaults file.
159 This will keep the perl interpreter disabled until the user enables
160 it.
161
162 If you can/want build more binaries, I recommend building a minimal
163 one with "--disable-everything" (very useful) and a maximal one with
164 "--enable-everything" (less useful, it will be very big due to a lot
165 of encodings built-in that increase download times and are rarely
166 used).
167
168 I need to make it setuid/setgid to support utmp/ptys on my OS, is this
169 safe?
170 It should be, starting with release 7.1. You are encouraged to
171 properly install urxvt with privileges necessary for your OS now.
172
173 When rxvt-unicode detects that it runs setuid or setgid, it will
174 fork into a helper process for privileged operations (pty handling
175 on some systems, utmp/wtmp/lastlog handling on others) and drop
176 privileges immediately. This is much safer than most other terminals
177 that keep privileges while running (but is more relevant to urxvt,
178 as it contains things as perl interpreters, which might be "helpful"
179 to attackers).
180
181 This forking is done as the very first within main(), which is very
182 early and reduces possible bugs to initialisation code run before
183 main(), or things like the dynamic loader of your system, which
184 should result in very little risk.
