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.

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

152 Likely not. While I honestly try to make it secure, and am probably 247 It should be, starting with release 7.1. You are encouraged to

158 security problems easily multiplies. 252 on some systems, utmp/wtmp/lastlog handling on others) and drop
253 privileges immediately. This is much safer than most other terminals
254 that keep privileges while running (but is more relevant to urxvt,
255 as it contains things as perl interpreters, which might be "helpful"
256 to attackers).

165
166 So, while setuid/setgid operation is supported and not a problem on
167 your typical single-user-no-other-logins unix desktop, always
168 remember that its an awful lot of code, most of which isn't checked
169 for security issues regularly.
