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 |
|
|
41 | |
|
|
42 | The cursor moves when selecting text in the current input line, how do I |
|
|
43 | switch this off? |
|
|
44 | During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs |
|
|
45 | strange escape sequences, how do I fix this? |
|
|
46 | These are caused by the "readline" perl extension. Under normal |
|
|
47 | circumstances, it will move your cursor around when you click into |
|
|
48 | the line that contains it. It tries hard not to do this at the wrong |
|
|
49 | moment, but when running a program that doesn't parse cursor |
|
|
50 | movements or in some cases during rlogin sessions, it fails to |
|
|
51 | detect this properly. |
|
|
52 | |
|
|
53 | You can permamently switch this feature off by disabling the |
|
|
54 | "readline" extension: |
|
|
55 | |
|
|
56 | URxvt.perl-ext-common: default,-readline |
|
|
57 | |
|
|
58 | Why doesn't rxvt-unicode read my resources? |
|
|
59 | Well, why, indeed? It does, in a way very similar to other X |
|
|
60 | applications. Most importantly, this means that if you or your OS |
|
|
61 | loads resources into the X display (the right way to do it), |
|
|
62 | rxvt-unicode will ignore any resource files in your home directory. |
|
|
63 | It will only read $HOME/.Xdefaults when no resources are attached to |
|
|
64 | the display. |
|
|
65 | |
|
|
66 | If you have or use an $HOME/.Xresources file, chances are that |
|
|
67 | resources are loaded into your X-server. In this case, you have to |
|
|
68 | re-login after every change (or run xrdb -merge $HOME/.Xresources). |
|
|
69 | |
|
|
70 | Also consider the form resources have to use: |
|
|
71 | |
|
|
72 | URxvt.resource: value |
|
|
73 | |
|
|
74 | If you want to use another form (there are lots of different ways of |
|
|
75 | specifying resources), make sure you understand wether and why it |
|
|
76 | works. If unsure, use the form above. |
|
|
77 | |
|
|
78 | I can't get transparency working, what am I doing wrong? |
|
|
79 | First of all, transparency isn't officially supported in |
|
|
80 | rxvt-unicode, so you are mostly on your own. Do not bug the author |
|
|
81 | about it (but you may bug everybody else). Also, if you can't get it |
|
|
82 | working consider it a rite of passage: ... and you failed. |
|
|
83 | |
|
|
84 | Here are four ways to get transparency. Do read the manpage and |
|
|
85 | option descriptions for the programs mentioned and rxvt-unicode. |
|
|
86 | Really, do it! |
|
|
87 | |
|
|
88 | 1. Use inheritPixmap: |
|
|
89 | |
|
|
90 | Esetroot wallpaper.jpg |
|
|
91 | rxvt -ip -tint red -sh 40 |
|
|
92 | |
|
|
93 | That works. If you think it doesn't, you lack transparency and |
|
|
94 | tinting support, or you are unable to read. |
|
|
95 | |
|
|
96 | 2. Use a simple pixmap and emulate pseudo-transparency. This enables |
|
|
97 | you to use effects other than tinting and shading: Just |
|
|
98 | shade/tint/whatever your picture with gimp: |
|
|
99 | |
|
|
100 | convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm |
|
|
101 | rxvt -pixmap background.xpm -pe automove-background |
|
|
102 | |
|
|
103 | That works. If you think it doesn't, you lack XPM and Perl support, |
|
|
104 | or you are unable to read. |
|
|
105 | |
|
|
106 | 3. Use an ARGB visual: |
|
|
107 | |
|
|
108 | rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc |
|
|
109 | |
|
|
110 | This requires XFT support, and the support of your X-server. If that |
|
|
111 | doesn't work for you, blame Xorg and Keith Packard. ARGB visuals |
|
|
112 | aren't there yet, no matter what they claim. Rxvt-Unicode contains |
|
|
113 | the neccessary bugfixes and workarounds for Xft and Xlib to make it |
|
|
114 | work, but that doesn't mean that your WM has the required kludges in |
|
|
115 | place. |
|
|
116 | |
|
|
117 | 4. Use xcompmgr and let it do the job: |
|
|
118 | |
|
|
119 | xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ |
|
|
120 | -set _NET_WM_WINDOW_OPACITY 0xc0000000 |
|
|
121 | |
|
|
122 | Then click on a window you want to make transparent. Replace |
|
|
123 | 0xc0000000 by other values to change the degree of opacity. If it |
|
|
124 | doesn't work and your server crashes, you got to keep the pieces. |
|
|
125 | |

261 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
129 | safe? |
262 | safe? |
130 | Likely not. While I honestly try to make it secure, and am probably |
263 | 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 |
264 | properly install urxvt with privileges necessary for your OS now. |
132 | freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode |
265 | |
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. |
266 | When rxvt-unicode detects that it runs setuid or setgid, it will |
135 | Besides, with the embedded perl interpreter the possibility for |
267 | fork into a helper process for privileged operations (pty handling |
136 | security problems easily multiplies. |
268 | on some systems, utmp/wtmp/lastlog handling on others) and drop |
|
|
269 | privileges immediately. This is much safer than most other terminals |
|
|
270 | that keep privileges while running (but is more relevant to urxvt, |
|
|
271 | as it contains things as perl interpreters, which might be "helpful" |
|
|
272 | to attackers). |
137 | |
273 | |
138 | Elevated privileges are only required for utmp and pty operations on |
274 | 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 |
275 | early and reduces possible bugs to initialisation code run before |
140 | privileges for ptys, but some need it for utmp support). It is |
276 | 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 |
277 | 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. |
