|
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 | Why doesn't rxvt-unicode read my resources? |
|
|
43 | Well, why, indeed? It does, in a way very similar to other X |
|
|
44 | applications. Most importantly, this means that if you or your OS |
|
|
45 | loads resources into the X display (the right way to do it), |
|
|
46 | rxvt-unicode will ignore any resource files in your home directory. |
|
|
47 | It will only read $HOME/.Xdefaults when no resources are attached to |
|
|
48 | the display. |
|
|
49 | |
|
|
50 | If you have or use an $HOME/.Xresources file, chances are that |
|
|
51 | resources are loaded into your X-server. In this case, you have to |
|
|
52 | re-login after every change (or run xrdb -merge $HOME/.Xresources). |
|
|
53 | |
|
|
54 | Also consider the form resources have to use: |
|
|
55 | |
|
|
56 | URxvt.resource: value |
|
|
57 | |
|
|
58 | If you want to use another form (there are lots of different ways of |
|
|
59 | specifying resources), make sure you understand wether and why it |
|
|
60 | works. If unsure, use the form above. |
|
|
61 | |
|
|
62 | I can't get transparency working, what am I doing wrong? |
|
|
63 | First of all, transparency isn't officially supported in |
|
|
64 | rxvt-unicode, so you are mostly on your own. Do not bug the author |
|
|
65 | about it (but you may bug everybody else). Also, if you can't get it |
|
|
66 | working consider it a rite of passage: ... and you failed. |
|
|
67 | |
|
|
68 | Here are four ways to get transparency. Do read the manpage and |
|
|
69 | option descriptions for the programs mentioned and rxvt-unicode. |
|
|
70 | Really, do it! |
|
|
71 | |
|
|
72 | 1. Use inheritPixmap: |
|
|
73 | |
|
|
74 | Esetroot wallpaper.jpg |
|
|
75 | rxvt -ip -tint red -sh 40 |
|
|
76 | |
|
|
77 | That works. If you think it doesn't, you lack transparency and |
|
|
78 | tinting support, or you are unable to read. |
|
|
79 | |
|
|
80 | 2. Use a simple pixmap and emulate pseudo-transparency. This enables |
|
|
81 | you to use effects other than tinting and shading: Just |
|
|
82 | shade/tint/whatever your picture with gimp: |
|
|
83 | |
|
|
84 | convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm |
|
|
85 | rxvt -pixmap background.xpm -pe automove-background |
|
|
86 | |
|
|
87 | That works. If you think it doesn't, you lack XPM and Perl support, |
|
|
88 | or you are unable to read. |
|
|
89 | |
|
|
90 | 3. Use an ARGB visual: |
|
|
91 | |
|
|
92 | rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc |
|
|
93 | |
|
|
94 | This requires XFT support, and the support of your X-server. If that |
|
|
95 | doesn't work for you, blame Xorg and Keith Packard. ARGB visuals |
|
|
96 | aren't there yet, no matter what they claim. Rxvt-Unicode contains |
|
|
97 | the neccessary bugfixes and workarounds for Xft and Xlib to make it |
|
|
98 | work, but that doesn't mean that your WM has the required kludges in |
|
|
99 | place. |
|
|
100 | |
|
|
101 | 4. Use xcompmgr and let it do the job: |
|
|
102 | |
|
|
103 | xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ |
|
|
104 | -set _NET_WM_WINDOW_OPACITY 0xc0000000 |
|
|
105 | |
|
|
106 | Then click on a window you want to make transparent. Replace |
|
|
107 | 0xc0000000 by other values to change the degree of opacity. If it |
|
|
108 | doesn't work and your server crashes, you got to keep the pieces. |
|
|
109 | |
|
|
110 | Isn't rxvt supposed to be small? Don't all those features bloat? |
|
|
111 | I often get asked about this, and I think, no, they didn't cause |
|
|
112 | extra bloat. If you compare a minimal rxvt and a minimal urxvt, you |
|
|
113 | can see that the urxvt binary is larger (due to some encoding tables |
|
|
114 | always being compiled in), but it actually uses less memory (RSS) |
|
|
115 | after startup. Even with "--disable-everything", this comparison is |
|
|
116 | a bit unfair, as many features unique to urxvt (locale, encoding |
|
|
117 | conversion, iso14755 etc.) are already in use in this mode. |
|
|
118 | |
|
|
119 | text data bss drs rss filename |
|
|
120 | 98398 1664 24 15695 1824 rxvt --disable-everything |
|
|
121 | 188985 9048 66616 18222 1788 urxvt --disable-everything |
|
|
122 | |
|
|
123 | When you "--enable-everything" (which _is_ unfair, as this involves |
|
|
124 | xft and full locale/XIM support which are quite bloaty inside libX11 |
|
|
125 | and my libc), the two diverge, but not unreasnobaly so. |
|
|
126 | |
|
|
127 | text data bss drs rss filename |
|
|
128 | 163431 2152 24 20123 2060 rxvt --enable-everything |
|
|
129 | 1035683 49680 66648 29096 3680 urxvt --enable-everything |
|
|
130 | |
|
|
131 | The very large size of the text section is explained by the |
|
|
132 | east-asian encoding tables, which, if unused, take up disk space but |
|
|
133 | nothing else and can be compiled out unless you rely on X11 core |
|
|
134 | fonts that use those encodings. The BSS size comes from the 64k |
|
|
135 | emergency buffer that my c++ compiler allocates (but of course |
|
|
136 | doesn't use unless you are out of memory). Also, using an xft font |
|
|
137 | instead of a core font immediately adds a few megabytes of RSS. Xft |
|
|
138 | indeed is responsible for a lot of RSS even when not used. |
|
|
139 | |
|
|
140 | Of course, due to every character using two or four bytes instead of |
|
|
141 | one, a large scrollback buffer will ultimately make rxvt-unicode use |
|
|
142 | more memory. |
|
|
143 | |
|
|
144 | Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), |
|
|
145 | this still fares rather well. And compared to some monsters like |
|
|
146 | gnome-terminal (21152k + extra 4204k in separate processes) or |
|
|
147 | konsole (22200k + extra 43180k in daemons that stay around after |
|
|
148 | exit, plus half a minute of startup time, including the hundreds of |
|
|
149 | warnings it spits out), it fares extremely well *g*. |
|
|
150 | |
|
|
151 | Why C++, isn't that unportable/bloated/uncool? |
|
|
152 | Is this a question? :) It comes up very often. The simple answer is: |
|
|
153 | I had to write it, and C++ allowed me to write and maintain it in a |
|
|
154 | fraction of the time and effort (which is a scarce resource for me). |
|
|
155 | Put even shorter: It simply wouldn't exist without C++. |
|
|
156 | |
|
|
157 | My personal stance on this is that C++ is less portable than C, but |
|
|
158 | in the case of rxvt-unicode this hardly matters, as its portability |
|
|
159 | limits are defined by things like X11, pseudo terminals, locale |
|
|
160 | support and unix domain sockets, which are all less portable than |
|
|
161 | C++ itself. |
|
|
162 | |
|
|
163 | Regarding the bloat, see the above question: It's easy to write |
|
|
164 | programs in C that use gobs of memory, an certainly possible to |
|
|
165 | write programs in C++ that don't. C++ also often comes with large |
|
|
166 | libraries, but this is not necessarily the case with GCC. Here is |
|
|
167 | what rxvt links against on my system with a minimal config: |
|
|
168 | |
|
|
169 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
170 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000) |
|
|
171 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000) |
|
|
172 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
173 | |
|
|
174 | And here is rxvt-unicode: |
|
|
175 | |
|
|
176 | libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) |
|
|
177 | libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000) |
|
|
178 | libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000) |
|
|
179 | libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000) |
|
|
180 | /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) |
|
|
181 | |
|
|
182 | No large bloated libraries (of course, none were linked in |
|
|
183 | statically), except maybe libX11 :) |
|
|
184 | |
|
|
185 | Does it support tabs, can I have a tabbed rxvt-unicode? |
|
|
186 | Beginning with version 7.3, there is a perl extension that |
|
|
187 | implements a simple tabbed terminal. It is installed by default, so |
|
|
188 | any of these should give you tabs: |
|
|
189 | |
|
|
190 | rxvt -pe tabbed |
|
|
191 | |
|
|
192 | URxvt.perl-ext-common: default,tabbed |
|
|
193 | |
|
|
194 | It will also work fine with tabbing functionality of many window |
|
|
195 | managers or similar tabbing programs, and its embedding-features |
|
|
196 | allow it to be embedded into other programs, as witnessed by |
|
|
197 | doc/rxvt-tabbed or the upcoming "Gtk2::URxvt" perl module, which |
|
|
198 | features a tabbed urxvt (murxvt) terminal as an example embedding |
|
|
199 | application. |
|
|
200 | |
|
|
201 | How do I know which rxvt-unicode version I'm using? |
|
|
202 | The version number is displayed with the usage (-h). Also the escape |
|
|
203 | sequence "ESC [ 8 n" sets the window title to the version number. |
|
|
204 | When using the rxvtc client, the version displayed is that of the |
|
|
205 | daemon. |
|
|
206 | |
|
|
207 | I am using Debian GNU/Linux and have a problem... |
|
|
208 | The Debian GNU/Linux package of rxvt-unicode in sarge contains large |
|
|
209 | patches that considerably change the behaviour of rxvt-unicode (but |
|
|
210 | unfortunately this notice has been removed). Before reporting a bug |
|
|
211 | to the original rxvt-unicode author please download and install the |
|
|
212 | genuine version (<http://software.schmorp.de#rxvt-unicode>) and try |
|
|
213 | to reproduce the problem. If you cannot, chances are that the |
|
|
214 | problems are specific to Debian GNU/Linux, in which case it should |
|
|
215 | be reported via the Debian Bug Tracking System (use "reportbug" to |
|
|
216 | report the bug). |
|
|
217 | |
|
|
218 | For other problems that also affect the Debian package, you can and |
|
|
219 | probably should use the Debian BTS, too, because, after all, it's |
|
|
220 | also a bug in the Debian version and it serves as a reminder for |
|
|
221 | other users that might encounter the same issue. |
|
|
222 | |
|
|
223 | I am maintaining rxvt-unicode for distribution/OS XXX, any |
|
|
224 | recommendation? |
|
|
225 | You should build one binary with the default options. configure now |
|
|
226 | enables most useful options, and the trend goes to making them |
|
|
227 | runtime-switchable, too, so there is usually no drawback to enbaling |
|
|
228 | them, except higher disk and possibly memory usage. The perl |
|
|
229 | interpreter should be enabled, as important functionality (menus, |
|
|
230 | selection, likely more in the future) depends on it. |
|
|
231 | |
|
|
232 | You should not overwrite the "perl-ext-common" snd "perl-ext" |
|
|
233 | resources system-wide (except maybe with "defaults"). This will |
|
|
234 | result in useful behaviour. If your distribution aims at low memory, |
|
|
235 | add an empty "perl-ext-common" resource to the app-defaults file. |
|
|
236 | This will keep the perl interpreter disabled until the user enables |
|
|
237 | it. |
|
|
238 | |
|
|
239 | If you can/want build more binaries, I recommend building a minimal |
|
|
240 | one with "--disable-everything" (very useful) and a maximal one with |
|
|
241 | "--enable-everything" (less useful, it will be very big due to a lot |
|
|
242 | of encodings built-in that increase download times and are rarely |
|
|
243 | used). |
|
|
244 | |
|
|
245 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this |
|
|
246 | safe? |
|
|
247 | It should be, starting with release 7.1. You are encouraged to |
|
|
248 | properly install urxvt with privileges necessary for your OS now. |
|
|
249 | |
|
|
250 | When rxvt-unicode detects that it runs setuid or setgid, it will |
|
|
251 | fork into a helper process for privileged operations (pty handling |
|
|
252 | on some systems, utmp/wtmp/lastlog handling on others) and drop |
|
|
253 | privileges immediately. This is much safer than most other terminals |
|
|
254 | that keep privileges while running (but is more relevant to urxvt, |
|
|
255 | as it contains things as perl interpreters, which might be "helpful" |
|
|
256 | to attackers). |
|
|
257 | |
|
|
258 | This forking is done as the very first within main(), which is very |
|
|
259 | early and reduces possible bugs to initialisation code run before |
|
|
260 | main(), or things like the dynamic loader of your system, which |
|
|
261 | should result in very little risk. |
|
|
262 | |
|
|
263 | When I log-in to another system it tells me about missing terminfo data? |
|
|
264 | The terminal description used by rxvt-unicode is not as widely |
|
|
265 | available as that for xterm, or even rxvt (for which the same |
|
|
266 | problem often arises). |
|
|
267 | |
|
|
268 | The correct solution for this problem is to install the terminfo, |
|
|
269 | this can be done like this (with ncurses' infocmp): |
|
|
270 | |
|
|
271 | REMOTE=remotesystem.domain |
|
|
272 | infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti" |
|
|
273 | |
|
|
274 | ... or by installing rxvt-unicode normally on the remote system, |
|
|
275 | |
|
|
276 | If you cannot or do not want to do this, then you can simply set |
|
|
277 | "TERM=rxvt" or even "TERM=xterm", and live with the small number of |
|
|
278 | problems arising, which includes wrong keymapping, less and |
|
|
279 | different colours and some refresh errors in fullscreen |
|
|
280 | applications. It's a nice quick-and-dirty workaround for rare cases, |
|
|
281 | though. |
|
|
282 | |
|
|
283 | If you always want to do this (and are fine with the consequences) |
|
|
284 | you can either recompile rxvt-unicode with the desired TERM value or |
|
|
285 | use a resource to set it: |
|
|
286 | |
|
|
287 | URxvt.termName: rxvt |
|
|
288 | |
|
|
289 | If you don't plan to use rxvt (quite common...) you could also |
|
|
290 | replace the rxvt terminfo file with the rxvt-unicode one. |
|
|
291 | |
|
|
292 | "tic" outputs some error when compiling the terminfo entry. |
|
|
293 | Most likely it's the empty definition for "enacs=". Just replace it |
|
|
294 | by "enacs=\E[0@" and try again. |
|
|
295 | |
|
|
296 | "bash"'s readline does not work correctly under rxvt. |
|
|
297 | I need a termcap file entry. |
|
|
298 | One reason you might want this is that some distributions or |
|
|
299 | operating systems still compile some programs using the |
|
|
300 | long-obsoleted termcap library (Fedora Core's bash is one example) |
|
|
301 | and rely on a termcap entry for "rxvt-unicode". |
|
|
302 | |
|
|
303 | You could use rxvt's termcap entry with resonable results in many |
|
|
304 | cases. You can also create a termcap entry by using terminfo's |
|
|
305 | infocmp program like this: |
|
|
306 | |
|
|
307 | infocmp -C rxvt-unicode |
|
|
308 | |
|
|
309 | Or you could use this termcap entry, generated by the command above: |
|
|
310 | |

332 | Why does "ls" no longer have coloured output? |
|
|
333 | The "ls" in the GNU coreutils unfortunately doesn't use terminfo to |
|
|
334 | decide wether a terminal has colour, but uses it's own configuration |
|
|
335 | file. Needless to say, "rxvt-unicode" is not in it's default file |
|
|
336 | (among with most other terminals supporting colour). Either add: |
|
|
337 | |
|
|
338 | TERM rxvt-unicode |
|
|
339 | |
|
|
340 | to "/etc/DIR_COLORS" or simply add: |
|
|
341 | |
|
|
342 | alias ls='ls --color=auto' |
|
|
343 | |
|
|
344 | to your ".profile" or ".bashrc". |
|
|
345 | |
|
|
346 | Why doesn't vim/emacs etc. use the 88 colour mode? |
|
|
347 | Why doesn't vim/emacs etc. make use of italic? |
|
|
348 | Why are the secondary screen-related options not working properly? |
|
|
349 | Make sure you are using "TERM=rxvt-unicode". Some pre-packaged |
|
|
350 | distributions (most notably Debian GNU/Linux) break rxvt-unicode by |
|
|
351 | setting "TERM" to "rxvt", which doesn't have these extra features. |
|
|
352 | Unfortunately, some of these (most notably, again, Debian GNU/Linux) |
|
|
353 | furthermore fail to even install the "rxvt-unicode" terminfo file, |
|
|
354 | so you will need to install it on your own (See the question When I |
|
|
355 | log-in to another system it tells me about missing terminfo data? on |
|
|
356 | how to do this). |
|
|
357 | |
|
|
358 | My numerical keypad acts weird and generates differing output? |
|
|
359 | Some Debian GNUL/Linux users seem to have this problem, although no |
|
|
360 | specific details were reported so far. It is possible that this is |
|
|
361 | caused by the wrong "TERM" setting, although the details of wether |
|
|
362 | and how this can happen are unknown, as "TERM=rxvt" should offer a |
|
|
363 | compatible keymap. See the answer to the previous question, and |
|
|
364 | please report if that helped. |
|
|
365 | |
|
|
366 | Rxvt-unicode does not seem to understand the selected encoding? |
|
|
367 | Unicode does not seem to work? |
|
|
368 | If you encounter strange problems like typing an accented character |
|
|
369 | but getting two unrelated other characters or similar, or if program |
|
|
370 | output is subtly garbled, then you should check your locale |
|
|
371 | settings. |
|
|
372 | |
|
|
373 | Rxvt-unicode must be started with the same "LC_CTYPE" setting as the |
|
|
374 | programs. Often rxvt-unicode is started in the "C" locale, while the |
|
|
375 | login script running within the rxvt-unicode window changes the |
|
|
376 | locale to something else, e.g. "en_GB.UTF-8". Needless to say, this |
|
|
377 | is not going to work. |
|
|
378 | |
|
|
379 | The best thing is to fix your startup environment, as you will |
|
|
380 | likely run into other problems. If nothing works you can try this in |
|
|
381 | your .profile. |
|
|
382 | |
|
|
383 | printf '\e]701;%s\007' "$LC_CTYPE" |
|
|
384 | |
|
|
385 | If this doesn't work, then maybe you use a "LC_CTYPE" specification |
|
|
386 | not supported on your systems. Some systems have a "locale" command |
|
|
387 | which displays this (also, "perl -e0" can be used to check locale |
|
|
388 | settings, as it will complain loudly if it cannot set the locale). |
|
|
389 | If it displays something like: |
|
|
390 | |
|
|
391 | locale: Cannot set LC_CTYPE to default locale: ... |
|
|
392 | |
|
|
393 | Then the locale you specified is not supported on your system. |
|
|
394 | |
|
|
395 | If nothing works and you are sure that everything is set correctly |
|
|
396 | then you will need to remember a little known fact: Some programs |
|
|
397 | just don't support locales :( |
|
|
398 | |
|
|
399 | Why do some characters look so much different than others? |
|
|
400 | How does rxvt-unicode choose fonts? |
|
|
401 | Most fonts do not contain the full range of Unicode, which is fine. |
|
|
402 | Chances are that the font you (or the admin/package maintainer of |
|
|
403 | your system/os) have specified does not cover all the characters you |
|
|
404 | want to display. |
|
|
405 | |
|
|
406 | rxvt-unicode makes a best-effort try at finding a replacement font. |
|
|
407 | Often the result is fine, but sometimes the chosen font looks |
|
|
408 | bad/ugly/wrong. Some fonts have totally strange characters that |
|
|
409 | don't resemble the correct glyph at all, and rxvt-unicode lacks the |
|
|
410 | artificial intelligence to detect that a specific glyph is wrong: it |
|
|
411 | has to believe the font that the characters it claims to contain |
|
|
412 | indeed look correct. |
|
|
413 | |
|
|
414 | In that case, select a font of your taste and add it to the font |
|
|
415 | list, e.g.: |
|
|
416 | |
|
|
417 | rxvt -fn basefont,font2,font3... |
|
|
418 | |
|
|
419 | When rxvt-unicode sees a character, it will first look at the base |
|
|
420 | font. If the base font does not contain the character, it will go to |
|
|
421 | the next font, and so on. Specifying your own fonts will also speed |
|
|
422 | up this search and use less resources within rxvt-unicode and the |
|
|
423 | X-server. |
|
|
424 | |
|
|
425 | The only limitation is that none of the fonts may be larger than the |
|
|
426 | base font, as the base font defines the terminal character cell |
|
|
427 | size, which must be the same due to the way terminals work. |
|
|
428 | |
|
|
429 | Why do some chinese characters look so different than others? |
|
|
430 | This is because there is a difference between script and language -- |
|
|
431 | rxvt-unicode does not know which language the text that is output |
|
|
432 | is, as it only knows the unicode character codes. If rxvt-unicode |
|
|
433 | first sees a japanese/chinese character, it might choose a japanese |
|
|
434 | font for display. Subsequent japanese characters will use that font. |
|
|
435 | Now, many chinese characters aren't represented in japanese fonts, |
|
|
436 | so when the first non-japanese character comes up, rxvt-unicode will |
|
|
437 | look for a chinese font -- unfortunately at this point, it will |
|
|
438 | still use the japanese font for chinese characters that are also in |
|
|
439 | the japanese font. |
|
|
440 | |
|
|
441 | The workaround is easy: just tag a chinese font at the end of your |
|
|
442 | font list (see the previous question). The key is to view the font |
|
|
443 | list as a preference list: If you expect more japanese, list a |
|
|
444 | japanese font first. If you expect more chinese, put a chinese font |
|
|
445 | first. |
|
|
446 | |
|
|
447 | In the future it might be possible to switch language preferences at |
|
|
448 | runtime (the internal data structure has no problem with using |
|
|
449 | different fonts for the same character at the same time, but no |
|
|
450 | interface for this has been designed yet). |
|
|
451 | |
|
|
452 | Until then, you might get away with switching fonts at runtime (see |
|
|
453 | "Can I switch the fonts at runtime?" later in this document). |
|
|
454 | |
|
|
455 | Why does rxvt-unicode sometimes leave pixel droppings? |
|
|
456 | Most fonts were not designed for terminal use, which means that |
|
|
457 | character size varies a lot. A font that is otherwise fine for |
|
|
458 | terminal use might contain some characters that are simply too wide. |
|
|
459 | Rxvt-unicode will avoid these characters. For characters that are |
|
|
460 | just "a bit" too wide a special "careful" rendering mode is used |
|
|
461 | that redraws adjacent characters. |
|
|
462 | |
|
|
463 | All of this requires that fonts do not lie about character sizes, |
|
|
464 | however: Xft fonts often draw glyphs larger than their acclaimed |
|
|
465 | bounding box, and rxvt-unicode has no way of detecting this (the |
|
|
466 | correct way is to ask for the character bounding box, which |
|
|
467 | unfortunately is wrong in these cases). |
|
|
468 | |
|
|
469 | It's not clear (to me at least), wether this is a bug in Xft, |
|
|
470 | freetype, or the respective font. If you encounter this problem you |
|
|
471 | might try using the "-lsp" option to give the font more height. If |
|
|
472 | that doesn't work, you might be forced to use a different font. |
|
|
473 | |
|
|
474 | All of this is not a problem when using X11 core fonts, as their |
|
|
475 | bounding box data is correct. |
|
|
476 | |
|
|
477 | On Solaris 9, many line-drawing characters are too wide. |
|
|
478 | Seems to be a known bug, read |
|
|
479 | <http://nixdoc.net/files/forum/about34198.html>. Some people use the |
|
|
480 | following ugly workaround to get non-double-wide-characters working: |
|
|
481 | |
|
|
482 | #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x) |
|
|
483 | |
|
|
484 | My Compose (Multi_key) key is no longer working. |
|
|
485 | The most common causes for this are that either your locale is not |
|
|
486 | set correctly, or you specified a preeditStyle that is not supported |
|
|
487 | by your input method. For example, if you specified OverTheSpot and |
|
|
488 | your input method (e.g. the default input method handling Compose |
|
|
489 | keys) does not support this (for instance because it is not visual), |
|
|
490 | then rxvt-unicode will continue without an input method. |
|
|
491 | |
|
|
492 | In this case either do not specify a preeditStyle or specify more |
|
|
493 | than one pre-edit style, such as OverTheSpot,Root,None. |
|
|
494 | |
|
|
495 | I cannot type "Ctrl-Shift-2" to get an ASCII NUL character due to ISO |
|
|
496 | 14755 |
|
|
497 | Either try "Ctrl-2" alone (it often is mapped to ASCII NUL even on |
|
|
498 | international keyboards) or simply use ISO 14755 support to your |
|
|
499 | advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for |
|
|
500 | other codes, too, such as "Ctrl-Shift-1-d" to type the default |
|
|
501 | telnet escape character and so on. |
|
|
502 | |
|
|
503 | How can I keep rxvt-unicode from using reverse video so much? |
|
|
504 | First of all, make sure you are running with the right terminal |
|
|
505 | settings ("TERM=rxvt-unicode"), which will get rid of most of these |
|
|
506 | effects. Then make sure you have specified colours for italic and |
|
|
507 | bold, as otherwise rxvt-unicode might use reverse video to simulate |
|
|
508 | the effect: |
|
|
509 | |
|
|
510 | URxvt.colorBD: white |
|
|
511 | URxvt.colorIT: green |
|
|
512 | |
|
|
513 | Some programs assume totally weird colours (red instead of blue), how |
|
|
514 | can I fix that? |
|
|
515 | For some unexplainable reason, some rare programs assume a very |
|
|
516 | weird colour palette when confronted with a terminal with more than |
|
|
517 | the standard 8 colours (rxvt-unicode supports 88). The right fix is, |
|
|
518 | of course, to fix these programs not to assume non-ISO colours |
|
|
519 | without very good reasons. |
|
|
520 | |
|
|
521 | In the meantime, you can either edit your "rxvt-unicode" terminfo |
|
|
522 | definition to only claim 8 colour support or use "TERM=rxvt", which |
|
|
523 | will fix colours but keep you from using other rxvt-unicode |
|
|
524 | features. |
|
|
525 | |
|
|
526 | I am on FreeBSD and rxvt-unicode does not seem to work at all. |
|
|
527 | Rxvt-unicode requires the symbol "__STDC_ISO_10646__" to be defined |
|
|
528 | in your compile environment, or an implementation that implements |
|
|
529 | it, wether it defines the symbol or not. "__STDC_ISO_10646__" |
|
|
530 | requires that wchar_t is represented as unicode. |
|
|
531 | |
|
|
532 | As you might have guessed, FreeBSD does neither define this symobl |
|
|
533 | nor does it support it. Instead, it uses it's own internal |
|
|
534 | representation of wchar_t. This is, of course, completely fine with |
|
|
535 | respect to standards. |
|
|
536 | |
|
|
537 | However, that means rxvt-unicode only works in "POSIX", "ISO-8859-1" |
|
|
538 | and "UTF-8" locales under FreeBSD (which all use Unicode as wchar_t. |
|
|
539 | |
|
|
540 | "__STDC_ISO_10646__" is the only sane way to support multi-language |
|
|
541 | apps in an OS, as using a locale-dependent (and non-standardized) |
|
|
542 | representation of wchar_t makes it impossible to convert between |
|
|
543 | wchar_t (as used by X11 and your applications) and any other |
|
|
544 | encoding without implementing OS-specific-wrappers for each and |
|
|
545 | every locale. There simply are no APIs to convert wchar_t into |
|
|
546 | anything except the current locale encoding. |
|
|
547 | |
|
|
548 | Some applications (such as the formidable mlterm) work around this |
|
|
549 | by carrying their own replacement functions for character set |
|
|
550 | handling with them, and either implementing OS-dependent hacks or |
|
|
551 | doing multiple conversions (which is slow and unreliable in case the |
|
|
552 | OS implements encodings slightly different than the terminal |
|
|
553 | emulator). |
|
|
554 | |
|
|
555 | The rxvt-unicode author insists that the right way to fix this is in |
|
|
556 | the system libraries once and for all, instead of forcing every app |
|
|
557 | to carry complete replacements for them :) |
|
|
558 | |
|
|
559 | I use Solaris 9 and it doesn't compile/work/etc. |
|
|
560 | Try the diff in doc/solaris9.patch as a base. It fixes the worst |
|
|
561 | problems with "wcwidth" and a compile problem. |
|
|
562 | |
|
|
563 | How can I use rxvt-unicode under cygwin? |
|
|
564 | rxvt-unicode should compile and run out of the box on cygwin, using |
|
|
565 | the X11 libraries that come with cygwin. libW11 emulation is no |
|
|
566 | longer supported (and makes no sense, either, as it only supported a |
|
|
567 | single font). I recommend starting the X-server in "-multiwindow" or |
|
|
568 | "-rootless" mode instead, which will result in similar look&feel as |
|
|
569 | the old libW11 emulation. |
|
|
570 | |
|
|
571 | At the time of this writing, cygwin didn't seem to support any |
|
|
572 | multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are |
|
|
573 | likely limited to 8-bit encodings. |
|
|
574 | |
|
|
575 | How does rxvt-unicode determine the encoding to use? |
|
|
576 | Is there an option to switch encodings? |
|
|
577 | Unlike some other terminals, rxvt-unicode has no encoding switch, |
|
|
578 | and no specific "utf-8" mode, such as xterm. In fact, it doesn't |
|
|
579 | even know about UTF-8 or any other encodings with respect to |
|
|
580 | terminal I/O. |
|
|
581 | |
|
|
582 | The reasons is that there exists a perfectly fine mechanism for |
|
|
583 | selecting the encoding, doing I/O and (most important) communicating |
|
|
584 | this to all applications so everybody agrees on character properties |
|
|
585 | such as width and code number. This mechanism is the *locale*. |
|
|
586 | Applications not using that info will have problems (for example, |
|
|
587 | "xterm" gets the width of characters wrong as it uses it's own, |
|
|
588 | locale-independent table under all locales). |
|
|
589 | |
|
|
590 | Rxvt-unicode uses the "LC_CTYPE" locale category to select encoding. |
|
|
591 | All programs doing the same (that is, most) will automatically agree |
|
|
592 | in the interpretation of characters. |
|
|
593 | |
|
|
594 | Unfortunately, there is no system-independent way to select locales, |
|
|
595 | nor is there a standard on how locale specifiers will look like. |
|
|
596 | |
|
|
597 | On most systems, the content of the "LC_CTYPE" environment variable |
|
|
598 | contains an arbitrary string which corresponds to an |
|
|
599 | already-installed locale. Common names for locales are |
|
|
600 | "en_US.UTF-8", "de_DE.ISO-8859-15", "ja_JP.EUC-JP", i.e. |
|
|
601 | "language_country.encoding", but other forms (i.e. "de" or "german") |
|
|
602 | are also common. |
|
|
603 | |
|
|
604 | Rxvt-unicode ignores all other locale categories, and except for the |
|
|
605 | encoding, ignores country or language-specific settings, i.e. |
|
|
606 | "de_DE.UTF-8" and "ja_JP.UTF-8" are the normally same to |
|
|
607 | rxvt-unicode. |
|
|
608 | |
|
|
609 | If you want to use a specific encoding you have to make sure you |
|
|
610 | start rxvt-unicode with the correct "LC_CTYPE" category. |
|
|
611 | |
|
|
612 | Can I switch locales at runtime? |
|
|
613 | Yes, using an escape sequence. Try something like this, which sets |
|
|
614 | rxvt-unicode's idea of "LC_CTYPE". |
|
|
615 | |
|
|
616 | printf '\e]701;%s\007' ja_JP.SJIS |
|
|
617 | |
|
|
618 | See also the previous answer. |
|
|
619 | |
|
|
620 | Sometimes this capability is rather handy when you want to work in |
|
|
621 | one locale (e.g. "de_DE.UTF-8") but some programs don't support it |
|
|
622 | (e.g. UTF-8). For example, I use this script to start "xjdic", which |
|
|
623 | first switches to a locale supported by xjdic and back later: |
|
|
624 | |
|
|
625 | printf '\e]701;%s\007' ja_JP.SJIS |
|
|
626 | xjdic -js |
|
|
627 | printf '\e]701;%s\007' de_DE.UTF-8 |
|
|
628 | |
|
|
629 | You can also use xterm's "luit" program, which usually works fine, |
|
|
630 | except for some locales where character width differs between |
|
|
631 | program- and rxvt-unicode-locales. |
|
|
632 | |
|
|
633 | Can I switch the fonts at runtime? |
|
|
634 | Yes, using an escape sequence. Try something like this, which has |
|
|
635 | the same effect as using the "-fn" switch, and takes effect |
|
|
636 | immediately: |
|
|
637 | |
|
|
638 | printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic" |
|
|
639 | |
|
|
640 | This is useful if you e.g. work primarily with japanese (and prefer |
|
|
641 | a japanese font), but you have to switch to chinese temporarily, |
|
|
642 | where japanese fonts would only be in your way. |
|
|
643 | |
|
|
644 | You can think of this as a kind of manual ISO-2022 switching. |
|
|
645 | |
|
|
646 | Why do italic characters look as if clipped? |
|
|
647 | Many fonts have difficulties with italic characters and hinting. For |
|
|
648 | example, the otherwise very nicely hinted font "xft:Bitstream Vera |
|
|
649 | Sans Mono" completely fails in it's italic face. A workaround might |
|
|
650 | be to enable freetype autohinting, i.e. like this: |
|
|
651 | |
|
|
652 | URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true |
|
|
653 | URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true |
|
|
654 | |
|
|
655 | My input method wants <some encoding> but I want UTF-8, what can I do? |
|
|
656 | You can specify separate locales for the input method and the rest |
|
|
657 | of the terminal, using the resource "imlocale": |
|
|
658 | |
|
|
659 | URxvt.imlocale: ja_JP.EUC-JP |
|
|
660 | |
|
|
661 | Now you can start your terminal with "LC_CTYPE=ja_JP.UTF-8" and |
|
|
662 | still use your input method. Please note, however, that you will not |
|
|
663 | be able to input characters outside "EUC-JP" in a normal way then, |
|
|
664 | as your input method limits you. |
|
|
665 | |
|
|
666 | Rxvt-unicode crashes when the X Input Method changes or exits. |
|
|
667 | Unfortunately, this is unavoidable, as the XIM protocol is racy by |
|
|
668 | design. Applications can avoid some crashes at the expense of memory |
|
|
669 | leaks, and Input Methods can avoid some crashes by careful ordering |
|
|
670 | at exit time. kinput2 (and derived input methods) generally |
|
|
671 | succeeds, while SCIM (or similar input methods) fails. In the end, |
|
|
672 | however, crashes cannot be completely avoided even if both sides |
|
|
673 | cooperate. |
|
|
674 | |
|
|
675 | So the only workaround is not to kill your Input Method Servers. |
|
|
676 | |
|
|
677 | Rxvt-unicode uses gobs of memory, how can I reduce that? |
|
|
678 | Rxvt-unicode tries to obey the rule of not charging you for |
|
|
679 | something you don't use. One thing you should try is to configure |
|
|
680 | out all settings that you don't need, for example, Xft support is a |
|
|
681 | resource hog by design, when used. Compiling it out ensures that no |
|
|
682 | Xft font will be loaded accidentally when rxvt-unicode tries to find |
|
|
683 | a font for your characters. |
|
|
684 | |
|
|
685 | Also, many people (me included) like large windows and even larger |
|
|
686 | scrollback buffers: Without "--enable-unicode3", rxvt-unicode will |
|
|
687 | use 6 bytes per screen cell. For a 160x?? window this amounts to |
|
|
688 | almost a kilobyte per line. A scrollback buffer of 10000 lines will |
|
|
689 | then (if full) use 10 Megabytes of memory. With "--enable-unicode3" |
|
|
690 | it gets worse, as rxvt-unicode then uses 8 bytes per screen cell. |
|
|
691 | |
|
|
692 | Can I speed up Xft rendering somehow? |
|
|
693 | Yes, the most obvious way to speed it up is to avoid Xft entirely, |
|
|
694 | as it is simply slow. If you still want Xft fonts you might try to |
|
|
695 | disable antialiasing (by appending ":antialias=false"), which saves |
|
|
696 | lots of memory and also speeds up rendering considerably. |
|
|
697 | |
|
|
698 | Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong? |
|
|
699 | Rxvt-unicode will use whatever you specify as a font. If it needs to |
|
|
700 | fall back to it's default font search list it will prefer X11 core |
|
|
701 | fonts, because they are small and fast, and then use Xft fonts. It |
|
|
702 | has antialiasing disabled for most of them, because the author |
|
|
703 | thinks they look best that way. |
|
|
704 | |
|
|
705 | If you want antialiasing, you have to specify the fonts manually. |
|
|
706 | |
|
|
707 | Mouse cut/paste suddenly no longer works. |
|
|
708 | Make sure that mouse reporting is actually turned off since killing |
|
|
709 | some editors prematurely may leave the mouse in mouse report mode. |
|
|
710 | I've heard that tcsh may use mouse reporting unless it otherwise |
|
|
711 | specified. A quick check is to see if cut/paste works when the Alt |
|
|
712 | or Shift keys are depressed. |
|
|
713 | |
|
|
714 | What's with this bold/blink stuff? |
|
|
715 | If no bold colour is set via "colorBD:", bold will invert text using |
|
|
716 | the standard foreground colour. |
|
|
717 | |
|
|
718 | For the standard background colour, blinking will actually make the |
|
|
719 | text blink when compiled with "--enable-blinking". with standard |
|
|
720 | colours. Without "--enable-blinking", the blink attribute will be |
|
|
721 | ignored. |
|
|
722 | |
|
|
723 | On ANSI colours, bold/blink attributes are used to set |
|
|
724 | high-intensity foreground/background colors. |
|
|
725 | |
|
|
726 | color0-7 are the low-intensity colors. |
|
|
727 | |
|
|
728 | color8-15 are the corresponding high-intensity colors. |
|
|
729 | |
|
|
730 | I don't like the screen colors. How do I change them? |
|
|
731 | You can change the screen colors at run-time using ~/.Xdefaults |
|
|
732 | resources (or as long-options). |
|
|
733 | |
|
|
734 | Here are values that are supposed to resemble a VGA screen, |
|
|
735 | including the murky brown that passes for low-intensity yellow: |
|
|
736 | |
|
|
737 | URxvt.color0: #000000 |
|
|
738 | URxvt.color1: #A80000 |
|
|
739 | URxvt.color2: #00A800 |
|
|
740 | URxvt.color3: #A8A800 |
|
|
741 | URxvt.color4: #0000A8 |
|
|
742 | URxvt.color5: #A800A8 |
|
|
743 | URxvt.color6: #00A8A8 |
|
|
744 | URxvt.color7: #A8A8A8 |
|
|
745 | |
|
|
746 | URxvt.color8: #000054 |
|
|
747 | URxvt.color9: #FF0054 |
|
|
748 | URxvt.color10: #00FF54 |
|
|
749 | URxvt.color11: #FFFF54 |

752 | URxvt.color14: #00FFFF |
|
|
753 | URxvt.color15: #FFFFFF |
|
|
754 | |
|
|
755 | And here is a more complete set of non-standard colors described |
|
|
756 | (not by me) as "pretty girly". |
|
|
757 | |
|
|
758 | URxvt.cursorColor: #dc74d1 |

777 | How can I start rxvtd in a race-free way? |
|
|
778 | Try "rxvtd -f -o", which tells rxvtd to open the display, create the |
|
|
779 | listening socket and then fork. |
|
|
780 | |
|
|
781 | What's with the strange Backspace/Delete key behaviour? |
|
|
782 | Assuming that the physical Backspace key corresponds to the |
|
|
783 | BackSpace keysym (not likely for Linux ... see the following |
|
|
784 | question) there are two standard values that can be used for |
|
|
785 | Backspace: "^H" and "^?". |
|
|
786 | |
|
|
787 | Historically, either value is correct, but rxvt-unicode adopts the |
|
|
788 | debian policy of using "^?" when unsure, because it's the one only |
|
|
789 | only correct choice :). |
|
|
790 | |
|
|
791 | Rxvt-unicode tries to inherit the current stty settings and uses the |
|
|
792 | value of `erase' to guess the value for backspace. If rxvt-unicode |
|
|
793 | wasn't started from a terminal (say, from a menu or by remote |
|
|
794 | shell), then the system value of `erase', which corresponds to |
|
|
795 | CERASE in <termios.h>, will be used (which may not be the same as |
|
|
796 | your stty setting). |
|
|
797 | |
|
|
798 | For starting a new rxvt-unicode: |
|
|
799 | |
|
|
800 | # use Backspace = ^H |
|
|
801 | $ stty erase ^H |
|
|
802 | $ rxvt |
|
|
803 | |
|
|
804 | # use Backspace = ^? |
|
|
805 | $ stty erase ^? |
|
|
806 | $ rxvt |
|
|
807 | |
|
|
808 | Toggle with "ESC [ 36 h" / "ESC [ 36 l". |
|
|
809 | |
|
|
810 | For an existing rxvt-unicode: |
|
|
811 | |
|
|
812 | # use Backspace = ^H |
|
|
813 | $ stty erase ^H |
|
|
814 | $ echo -n "^[[36h" |
|
|
815 | |
|
|
816 | # use Backspace = ^? |
|
|
817 | $ stty erase ^? |
|
|
818 | $ echo -n "^[[36l" |
|
|
819 | |
|
|
820 | This helps satisfy some of the Backspace discrepancies that occur, |
|
|
821 | but if you use Backspace = "^H", make sure that the termcap/terminfo |
|
|
822 | value properly reflects that. |
|
|
823 | |
|
|
824 | The Delete key is a another casualty of the ill-defined Backspace |
|
|
825 | problem. To avoid confusion between the Backspace and Delete keys, |
|
|
826 | the Delete key has been assigned an escape sequence to match the |
|
|
827 | vt100 for Execute ("ESC [ 3 ~") and is in the supplied |
|
|
828 | termcap/terminfo. |
|
|
829 | |
|
|
830 | Some other Backspace problems: |
|
|
831 | |
|
|
832 | some editors use termcap/terminfo, some editors (vim I'm told) |
|
|
833 | expect Backspace = ^H, GNU Emacs (and Emacs-like editors) use ^H for |
|
|
834 | help. |
|
|
835 | |
|
|
836 | Perhaps someday this will all be resolved in a consistent manner. |
|
|
837 | |
|
|
838 | I don't like the key-bindings. How do I change them? |
|
|
839 | There are some compile-time selections available via configure. |
|
|
840 | Unless you have run "configure" with the "--disable-resources" |
|
|
841 | option you can use the `keysym' resource to alter the keystrings |
|
|
842 | associated with keysyms. |
|
|
843 | |
|
|
844 | Here's an example for a URxvt session started using "rxvt -name |
|
|

|
|
870 | I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How |
|
|
871 | do I make use of them? For example, the Sun Keyboard type 4 has the |
|
|
872 | following mappings that rxvt-unicode doesn't recognize. |
|
|
873 | KP_Insert == Insert |
|
|
874 | F22 == Print |
|
|
875 | F27 == Home |
|
|
876 | F29 == Prior |
|
|
877 | F33 == End |
|
|
878 | F35 == Next |
|
|
879 | |
|
|
880 | Rather than have rxvt-unicode try to accommodate all the various |
|
|
881 | possible keyboard mappings, it is better to use `xmodmap' to remap |
|
|
882 | the keys as required for your particular machine. |
|
|
883 | |
|
|
884 | How do I distinguish wether I'm running rxvt-unicode or a regular xterm? |
|
|
885 | I need this to decide about setting colors etc. |
|
|
886 | rxvt and rxvt-unicode always export the variable "COLORTERM", so you |
|
|
887 | can check and see if that is set. Note that several programs, JED, |
|
|
888 | slrn, Midnight Commander automatically check this variable to decide |
|
|
889 | whether or not to use color. |
|
|
890 | |
|
|
891 | How do I set the correct, full IP address for the DISPLAY variable? |
|
|
892 | If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled |
|
|
893 | insecure mode then it is possible to use the following shell script |
|
|
894 | snippets to correctly set the display. If your version of |
|
|
895 | rxvt-unicode wasn't also compiled with ESCZ_ANSWER (as assumed in |
|
|
896 | these snippets) then the COLORTERM variable can be used to |
|
|
897 | distinguish rxvt-unicode from a regular xterm. |

915 | How do I compile the manual pages for myself? |
|
|
916 | You need to have a recent version of perl installed as |
|
|
917 | /usr/bin/perl, one that comes with pod2man, pod2text and pod2html. |
|
|
918 | Then go to the doc subdirectory and enter "make alldoc". |
