2 The new selection selects pieces that are too big, how can I select single words?
3 If you want to select e.g. alphanumeric words, you can use the following
4 setting:
5
6 URxvt.selection.pattern-0: ([[:word:]]+)
7
8 If you click more than twice, the selection will be extended more and
9 more.
10
11 To get a selection that is very similar to the old code, try this
12 pattern:
13
14 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
15
16 Please also note that the *LeftClick Shift-LeftClik* combination also
17 selects words like the old code.

39 The cursor moves when selecting text in the current input line, how do I switch this off?
40 See next entry.
41
42 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
43 These are caused by the "readline" perl extension. Under normal
44 circumstances, it will move your cursor around when you click into the
45 line that contains it. It tries hard not to do this at the wrong moment,
46 but when running a program that doesn't parse cursor movements or in
47 some cases during rlogin sessions, it fails to detect this properly.
48
49 You can permamently switch this feature off by disabling the "readline"
50 extension:
51
52 URxvt.perl-ext-common: default,-readline
53
54 Why doesn't rxvt-unicode read my resources?
55 Well, why, indeed? It does, in a way very similar to other X
56 applications. Most importantly, this means that if you or your OS loads
57 resources into the X display (the right way to do it), rxvt-unicode will
58 ignore any resource files in your home directory. It will only read
59 $HOME/.Xdefaults when no resources are attached to the display.
60
61 If you have or use an $HOME/.Xresources file, chances are that resources
62 are loaded into your X-server. In this case, you have to re-login after
63 every change (or run xrdb -merge $HOME/.Xresources).
64
65 Also consider the form resources have to use:
66
67 URxvt.resource: value
68
69 If you want to use another form (there are lots of different ways of
70 specifying resources), make sure you understand wether and why it works.
71 If unsure, use the form above.
72
73 I can't get transparency working, what am I doing wrong?
74 First of all, transparency isn't officially supported in rxvt-unicode,
75 so you are mostly on your own. Do not bug the author about it (but you
76 may bug everybody else). Also, if you can't get it working consider it a
77 rite of passage: ... and you failed.
78
79 Here are four ways to get transparency. Do read the manpage and option
80 descriptions for the programs mentioned and rxvt-unicode. Really, do it!
81
82 1. Use inheritPixmap:
83
84 Esetroot wallpaper.jpg
85 rxvt -ip -tint red -sh 40
86
87 That works. If you think it doesn't, you lack transparency and tinting
88 support, or you are unable to read.
89
90 2. Use a simple pixmap and emulate pseudo-transparency. This enables you
91 to use effects other than tinting and shading: Just shade/tint/whatever
92 your picture with gimp:
93
94 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
95 rxvt -pixmap background.xpm -pe automove-background
96
97 That works. If you think it doesn't, you lack XPM and Perl support, or
98 you are unable to read.
99
100 3. Use an ARGB visual:
101
102 rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
103
104 This requires XFT support, and the support of your X-server. If that
105 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
106 there yet, no matter what they claim. Rxvt-Unicode contains the
107 neccessary bugfixes and workarounds for Xft and Xlib to make it work,
108 but that doesn't mean that your WM has the required kludges in place.
109
110 4. Use xcompmgr and let it do the job:
111
112 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
113 -set _NET_WM_WINDOW_OPACITY 0xc0000000
114
115 Then click on a window you want to make transparent. Replace 0xc0000000
116 by other values to change the degree of opacity. If it doesn't work and
117 your server crashes, you got to keep the pieces.
118

152 Likely not. While I honestly try to make it secure, and am probably 249 install urxvt with privileges necessary for your OS now.
153 not bad at it, I think it is simply unreasonable to expect all of
154 freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
155 itself to all be secure. Also, rxvt-unicode disables some options
156 when it detects that it runs setuid or setgid, which is not nice.
157 Besides, with the embedded perl interpreter the possibility for
158 security problems easily multiplies.
159 250
160 Elevated privileges are only required for utmp and pty operations on 251 When rxvt-unicode detects that it runs setuid or setgid, it will fork
161 some systems (for example, GNU/Linux doesn't need any extra 252 into a helper process for privileged operations (pty handling on some
162 privileges for ptys, but some need it for utmp support). It is 253 systems, utmp/wtmp/lastlog handling on others) and drop privileges

164 yet done. 255 privileges while running (but is more relevant to urxvt, as it contains
256 things as perl interpreters, which might be "helpful" to attackers).
165 257
166 So, while setuid/setgid operation is supported and not a problem on 258 This forking is done as the very first within main(), which is very
167 your typical single-user-no-other-logins unix desktop, always 259 early and reduces possible bugs to initialisation code run before
168 remember that its an awful lot of code, most of which isn't checked 260 main(), or things like the dynamic loader of your system, which should
