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 | Isn't rxvt supposed to be small? Don't all those features bloat? |
|
|
43 | I often get asked about this, and I think, no, they didn't cause |
|
|
44 | extra bloat. If you compare a minimal rxvt and a minimal urxvt, you |
|
|
45 | can see that the urxvt binary is larger (due to some encoding tables |
|
|
46 | always being compiled in), but it actually uses less memory (RSS) |
|
|
47 | after startup. Even with "--disable-everything", this comparison is |
|
|
48 | a bit unfair, as many features unique to urxvt (locale, encoding |
|
|
49 | conversion, iso14755 etc.) are already in use in this mode. |
|
|

|
|
53 | 188985 9048 66616 18222 1788 urxvt --disable-everything |
|
|
54 | |
|
|
55 | When you "--enable-everything" (which _is_ unfair, as this involves |
|
|
56 | xft and full locale/XIM support which are quite bloaty inside libX11 |
|
|
57 | and my libc), the two diverge, but not unreasnobaly so. |
|
|

|
|
59 | text data bss drs rss filename |
|
|
60 | 163431 2152 24 20123 2060 rxvt --enable-everything |
|
|
61 | 1035683 49680 66648 29096 3680 urxvt --enable-everything |
|
|
62 | |
|
|
63 | The very large size of the text section is explained by the |
|
|
64 | east-asian encoding tables, which, if unused, take up disk space but |
|
|
65 | nothing else and can be compiled out unless you rely on X11 core |
|
|
66 | fonts that use those encodings. The BSS size comes from the 64k |
|
|
67 | emergency buffer that my c++ compiler allocates (but of course |
|
|
68 | doesn't use unless you are out of memory). Also, using an xft font |
|
|
69 | instead of a core font immediately adds a few megabytes of RSS. Xft |
|
|
70 | indeed is responsible for a lot of RSS even when not used. |
|
|
71 | |
|
|
72 | Of course, due to every character using two or four bytes instead of |
|
|
73 | one, a large scrollback buffer will ultimately make rxvt-unicode use |
|
|
74 | more memory. |
|
|
75 | |
|
|
76 | Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), |
|
|
77 | this still fares rather well. And compared to some monsters like |
|
|
78 | gnome-terminal (21152k + extra 4204k in separate processes) or |
|
|
79 | konsole (22200k + extra 43180k in daemons that stay around after |
|
|
80 | exit, plus half a minute of startup time, including the hundreds of |
|
|
81 | warnings it spits out), it fares extremely well *g*. |
|

|
83 | Why C++, isn't that unportable/bloated/uncool? |
|
|
84 | Is this a question? :) It comes up very often. The simple answer is: |
|
|
85 | I had to write it, and C++ allowed me to write and maintain it in a |
|
|
86 | fraction of the time and effort (which is a scarce resource for me). |
|
|
87 | Put even shorter: It simply wouldn't exist without C++. |
|
|
88 | |
|
|
89 | My personal stance on this is that C++ is less portable than C, but |
|
|
90 | in the case of rxvt-unicode this hardly matters, as its portability |
|
|
91 | limits are defined by things like X11, pseudo terminals, locale |
|
|
92 | support and unix domain sockets, which are all less portable than |
|
|
93 | C++ itself. |
|
|
94 | |
|
|
95 | Regarding the bloat, see the above question: It's easy to write |
|
|
96 | programs in C that use gobs of memory, an certainly possible to |
|
|
97 | write programs in C++ that don't. C++ also often comes with large |
|
|
98 | libraries, but this is not necessarily the case with GCC. Here is |
|
|
99 | what rxvt links against on my system with a minimal config: |
|
|
100 | |
|
|
101 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
102 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000) |
|
|
103 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000) |
|
|
104 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
105 | |
|
|
106 | And here is rxvt-unicode: |
|
|
107 | |
|
|
108 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
109 | libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000) |
|
|
110 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000) |
|
|
111 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000) |
|
|
112 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
113 | |
|
|
114 | No large bloated libraries (of course, none were linked in |
|
|
115 | statically), except maybe libX11 :) |
|
|
116 | |
|
|
117 | Does it support tabs, can I have a tabbed rxvt-unicode? |
|
|
118 | rxvt-unicode does not directly support tabs. It will work fine with |
|
|
119 | tabbing functionality of many window managers or similar tabbing |
|
|
120 | programs, and its embedding-features allow it to be embedded into |
|
|
121 | other programs, as witnessed by doc/rxvt-tabbed or the upcoming |
|
|
122 | "Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt) |
|
|
123 | terminal as an example embedding application. |

|
|
147 | I am maintaining rxvt-unicode for distribution/OS XXX, any |
|
|
148 | recommendation? |
|
|
149 | You should build one binary with the default options. configure now |
|
|
150 | enables most useful options, and the trend goes to making them |
|
|
151 | runtime-switchable, too, so there is usually no drawback to enbaling |
|
|
152 | them, except higher disk and possibly memory usage. The perl |
|
|
153 | interpreter should be enabled, as important functionality (menus, |
|
|
154 | selection, likely more in the future) depends on it. |
|
|
155 | |
|
|
156 | You should not overwrite the "perl-ext-common" snd "perl-ext" |
|
|
157 | resources system-wide (except maybe with "defaults"). This will |
|
|
158 | result in useful behaviour. If your distribution aims at low memory, |
|
|
159 | add an empty "perl-ext-common" resource to the app-defaults file. |
|
|
160 | This will keep the perl interpreter disabled until the user enables |
|
|
161 | it. |
|
|
162 | |
|
|
163 | If you can/want build more binaries, I recommend building a minimal |
|
|
164 | one with "--disable-everything" (very useful) and a maximal one with |
|
|
165 | "--enable-everything" (less useful, it will be very big due to a lot |
|
|
166 | of encodings built-in that increase download times and are rarely |
|
|
167 | used). |
|
|
168 | |
|
|
169 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
|
|
170 | safe? |
|
|
171 | It should be, starting with release 7.1. You are encouraged to |
|
|
172 | properly install urxvt with privileges necessary for your OS now. |
|
|
173 | |
|
|
174 | When rxvt-unicode detects that it runs setuid or setgid, it will |
|
|
175 | fork into a helper process for privileged operations (pty handling |
|
|
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). |
|
|
181 | |
|
|
182 | This forking is done as the very first within main(), which is very |
|
|
183 | early and reduces possible bugs to initialisation code run before |
|
|
184 | main(), or things like the dynamic loader of your system, which |
|
|
185 | should result in very little risk. |
