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. |

168 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
| 151 | safe? |
169 | safe? |
| 152 | Likely not. While I honestly try to make it secure, and am probably |
170 | It should be, starting with release 7.1. You are encouraged to |
| 153 | not bad at it, I think it is simply unreasonable to expect all of |
171 | properly install urxvt with privileges necessary for your OS now. |
| 154 | freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode |
172 | |
| 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. |
173 | When rxvt-unicode detects that it runs setuid or setgid, it will |
| 157 | Besides, with the embedded perl interpreter the possibility for |
174 | fork into a helper process for privileged operations (pty handling |
| 158 | security problems easily multiplies. |
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). |
| 159 | |
180 | |
| 160 | Elevated privileges are only required for utmp and pty operations on |
181 | This forking is done as the very first within main(), which is very |
| 161 | some systems (for example, GNU/Linux doesn't need any extra |
182 | early and reduces possible bugs to initialisation code run before |
| 162 | privileges for ptys, but some need it for utmp support). It is |
183 | main(), or things like the dynamic loader of your system, which |
| 163 | planned to mvoe this into a forked handler process, but this is not |
184 | should result in very little risk. |
| 164 | yet done. |
|
|
| 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. |
