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 |

169 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
| 129 | safe? |
170 | safe? |
| 130 | Likely not. While I honestly try to make it secure, and am probably |
171 | It should be, starting with release 7.1. You are encouraged to |
| 131 | not bad at it, I think it is simply unreasonable to expect all of |
172 | properly install urxvt with privileges necessary for your OS now. |
| 132 | freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode |
173 | |
| 133 | itself to all be secure. Also, rxvt-unicode disables some options |
|
|
| 134 | when it detects that it runs setuid or setgid, which is not nice. |
174 | When rxvt-unicode detects that it runs setuid or setgid, it will |
| 135 | Besides, with the embedded perl interpreter the possibility for |
175 | fork into a helper process for privileged operations (pty handling |
| 136 | security problems easily multiplies. |
176 | on some systems, utmp/wtmp/lastlog handling on others) and drop |
|
|
177 | privileges immediately. This is much safer than most other terminals |
|
|
178 | that keep privileges while running (but is more relevant to urxvt, |
|
|
179 | as it contains things as perl interpreters, which might be "helpful" |
|
|
180 | to attackers). |
| 137 | |
181 | |
| 138 | Elevated privileges are only required for utmp and pty operations on |
182 | This forking is done as the very first within main(), which is very |
| 139 | some systems (for example, GNU/Linux doesn't need any extra |
183 | early and reduces possible bugs to initialisation code run before |
| 140 | privileges for ptys, but some need it for utmp support). It is |
184 | main(), or things like the dynamic loader of your system, which |
| 141 | planned to mvoe this into a forked handler process, but this is not |
185 | should result in very little risk. |
| 142 | yet done. |
|
|
| 143 | |
|
|
| 144 | So, while setuid/setgid operation is supported and not a problem on |
|
|
| 145 | your typical single-user-no-other-logins unix desktop, always |
|
|
| 146 | remember that its an awful lot of code, most of which isn't checked |
|
|
| 147 | for security issues regularly. |
