23 | The new selection selects pieces that are too big/too small, can I |
|
|
24 | change this? |
|
|
25 | Yes. For example, if you want to select smaller pieces ("words") you |
|
|
26 | can use the following resource: |
|
|
27 | |
|
|
28 | URxvt.selection.pattern-0: ([[:word:]]+) |
|
|
29 | |
|
|
30 | If you click more than twice, the selection will be extended more |
|
|
31 | and more. |
|
|
32 | |
|
|
33 | To get a selection that is very similar to the old code, try this |
|
|
34 | pattern: |
|
|
35 | |
|
|
36 | URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) |
|
|
37 | |
|
|
38 | I don't like the new selection/popups/hotkeys/perl, how do I |
|
|
39 | change/disable it? |
|
|
40 | You can disable the perl extension completely by setting the |
|
|
41 | perl-ext-common resource to the empty string, which also keeps |
|
|
42 | rxvt-unicode from initialising perl, saving memory. |
|
|
43 | |
|
|
44 | If you only want to disable specific features, you first have to |
|
|
45 | identify which perl extension is responsible. For this, read the |
|
|
46 | section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For |
|
|
47 | example, to disable the selection-popup and option-popup, specify |
|
|
48 | this perl-ext-common resource: |
|
|
49 | |
|
|
50 | URxvt.perl-ext-common: default,-selection-popup,-option-popup |
|
|
51 | |
|
|
52 | This will keep the default extensions, but disable the two popup |
|
|
53 | extensions. Some extensions can also be configured, for example, |
|
|
54 | scrollback search mode is triggered by M-s. You can move it to any |
|
|
55 | other combination either by setting the searchable-scrollback |
|
|
56 | resource: |
|
|
57 | |
|
|
58 | URxvt.searchable-scrollback: CM-s |

163 | |
|
|
164 | I am maintaining rxvt-unicode for distribution/OS XXX, any |
|
|
165 | recommendation? |
|
|
166 | You should build one binary with the default options. configure now |
|
|
167 | enables most useful options, and the trend goes to making them |
|
|
168 | runtime-switchable, too, so there is usually no drawback to enbaling |
|
|
169 | them, except higher disk and possibly memory usage. The perl |
|
|
170 | interpreter should be enabled, as important functionality (menus, |
|
|
171 | selection, likely more in the future) depends on it. |
|
|
172 | |
|
|
173 | You should not overwrite the "perl-ext-common" snd "perl-ext" |
|
|
174 | resources system-wide (except maybe with "defaults"). This will |
|
|
175 | result in useful behaviour. If your distribution aims at low memory, |
|
|
176 | add an empty "perl-ext-common" resource to the app-defaults file. |
|
|
177 | This will keep the perl interpreter disabled until the user enables |
|
|
178 | it. |
|
|
179 | |
|
|
180 | If you can/want build more binaries, I recommend building a minimal |
|
|
181 | one with "--disable-everything" (very useful) and a maximal one with |
|
|
182 | "--enable-everything" (less useful, it will be very big due to a lot |
|
|
183 | of encodings built-in that increase download times and are rarely |
|
|
184 | used). |
|
|
185 | |
|
|
186 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
|
|
187 | safe? |
|
|
188 | Likely not. While I honestly try to make it secure, and am probably |
|
|
189 | not bad at it, I think it is simply unreasonable to expect all of |
|
|
190 | freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode |
|
|
191 | itself to all be secure. Also, rxvt-unicode disables some options |
|
|
192 | when it detects that it runs setuid or setgid, which is not nice. |
|
|
193 | Besides, with the embedded perl interpreter the possibility for |
|
|
194 | security problems easily multiplies. |
|
|
195 | |
|
|
196 | Elevated privileges are only required for utmp and pty operations on |
|
|
197 | some systems (for example, GNU/Linux doesn't need any extra |
|
|
198 | privileges for ptys, but some need it for utmp support). It is |
|
|
199 | planned to mvoe this into a forked handler process, but this is not |
|
|
200 | yet done. |
|
|
201 | |
|
|
202 | So, while setuid/setgid operation is supported and not a problem on |
|
|
203 | your typical single-user-no-other-logins unix desktop, always |
|
|
204 | remember that its an awful lot of code, most of which isn't checked |
|
|
205 | for security issues regularly. |
