|
|

7 | |
6 | URxvt.selection.pattern-0: ([[:word:]]+) |
8 | I use Gentoo, and I have a problem... |
|
|
9 | There are three big problems with Gentoo Linux: first of all, most if |
|
|
10 | not all Gentoo systems are completely broken (missing or mismatched |
|
|
11 | header files, broken compiler etc. are just the tip of the iceberg); |
|
|
12 | secondly, the Gentoo maintainer thinks it is a good idea to add broken |
|
|
13 | patches to the code; and lastly, it should be called Gentoo GNU/Linux. |
7 | |
14 | |
8 | If you click more than twice, the selection will be extended more and |
15 | For these reasons, it is impossible to support rxvt-unicode on Gentoo. |
9 | more. |
16 | Problems appearing on Gentoo systems will usually simply be ignored |
|
|
17 | unless they can be reproduced on non-Gentoo systems. |
10 | |
18 | |
11 | To get a selection that is very similar to the old code, try this |
19 | Does it support tabs, can I have a tabbed rxvt-unicode? |
12 | pattern: |
20 | Beginning with version 7.3, there is a perl extension that implements a |
|
|
21 | simple tabbed terminal. It is installed by default, so any of these |
|
|
22 | should give you tabs: |
13 | |
23 | |
14 | URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) |
24 | urxvt -pe tabbed |
15 | |
25 | |
16 | Please also note that the *LeftClick Shift-LeftClik* combination also |
|
|
17 | selects words like the old code. |
|
|
18 | |
|
|
19 | I don't like the new selection/popups/hotkeys/perl, how do I change/disable it? |
|
|
20 | You can disable the perl extension completely by setting the |
|
|
21 | perl-ext-common resource to the empty string, which also keeps |
|
|
22 | rxvt-unicode from initialising perl, saving memory. |
|
|
23 | |
|
|
24 | If you only want to disable specific features, you first have to |
|
|
25 | identify which perl extension is responsible. For this, read the section |
|
|
26 | PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For example, to |
|
|
27 | disable the selection-popup and option-popup, specify this |
|
|
28 | perl-ext-common resource: |
|
|
29 | |
|
|
30 | URxvt.perl-ext-common: default,-selection-popup,-option-popup |
|
|
31 | |
|
|
32 | This will keep the default extensions, but disable the two popup |
|
|
33 | extensions. Some extensions can also be configured, for example, |
|
|
34 | scrollback search mode is triggered by M-s. You can move it to any other |
|
|
35 | combination either by setting the searchable-scrollback resource: |
|
|
36 | |
|
|
37 | URxvt.searchable-scrollback: CM-s |
|
|
38 | |
|
|
39 | The cursor moves when selecting text in the current input line, how do I switch this off? |
|
|
40 | See next entry. |
|
|
41 | |
|
|
42 | During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this? |
|
|
43 | These are caused by the "readline" perl extension. Under normal |
|
|
44 | circumstances, it will move your cursor around when you click into the |
|
|
45 | line that contains it. It tries hard not to do this at the wrong moment, |
|
|
46 | but when running a program that doesn't parse cursor movements or in |
|
|
47 | some cases during rlogin sessions, it fails to detect this properly. |
|
|
48 | |
|
|
49 | You can permamently switch this feature off by disabling the "readline" |
|
|
50 | extension: |
|
|
51 | |
|
|
52 | URxvt.perl-ext-common: default,-readline |
26 | URxvt.perl-ext-common: default,tabbed |
53 | |
27 | |
54 | Why doesn't rxvt-unicode read my resources? |
28 | It will also work fine with tabbing functionality of many window |
55 | Well, why, indeed? It does, in a way very similar to other X |
29 | managers or similar tabbing programs, and its embedding-features allow |
56 | applications. Most importantly, this means that if you or your OS loads |
30 | it to be embedded into other programs, as witnessed by doc/rxvt-tabbed |
57 | resources into the X display (the right way to do it), rxvt-unicode will |
31 | or the upcoming "Gtk2::URxvt" perl module, which features a tabbed urxvt |
58 | ignore any resource files in your home directory. It will only read |
32 | (murxvt) terminal as an example embedding application. |
59 | $HOME/.Xdefaults when no resources are attached to the display. |
|
|
60 | |
33 | |
61 | If you have or use an $HOME/.Xresources file, chances are that resources |
34 | How do I know which rxvt-unicode version I'm using? |
62 | are loaded into your X-server. In this case, you have to re-login after |
35 | The version number is displayed with the usage (-h). Also the escape |
63 | every change (or run xrdb -merge $HOME/.Xresources). |
36 | sequence "ESC [ 8 n" sets the window title to the version number. When |
|
|
37 | using the urxvtc client, the version displayed is that of the daemon. |
64 | |
38 | |
65 | Also consider the form resources have to use: |
39 | Rxvt-unicode uses gobs of memory, how can I reduce that? |
|
|
40 | Rxvt-unicode tries to obey the rule of not charging you for something |
|
|
41 | you don't use. One thing you should try is to configure out all settings |
|
|
42 | that you don't need, for example, Xft support is a resource hog by |
|
|
43 | design, when used. Compiling it out ensures that no Xft font will be |
|
|
44 | loaded accidentally when rxvt-unicode tries to find a font for your |
|
|
45 | characters. |
66 | |
46 | |
67 | URxvt.resource: value |
47 | Also, many people (me included) like large windows and even larger |
|
|
48 | scrollback buffers: Without "--enable-unicode3", rxvt-unicode will use 6 |
|
|
49 | bytes per screen cell. For a 160x?? window this amounts to almost a |
|
|
50 | kilobyte per line. A scrollback buffer of 10000 lines will then (if |
|
|
51 | full) use 10 Megabytes of memory. With "--enable-unicode3" it gets |
|
|
52 | worse, as rxvt-unicode then uses 8 bytes per screen cell. |
68 | |
53 | |
69 | If you want to use another form (there are lots of different ways of |
54 | How can I start urxvtd in a race-free way? |
70 | specifying resources), make sure you understand wether and why it works. |
55 | Try "urxvtd -f -o", which tells urxvtd to open the display, create the |
71 | If unsure, use the form above. |
56 | listening socket and then fork. |
72 | |
57 | |
73 | I can't get transparency working, what am I doing wrong? |
58 | How can I start urxvtd automatically when I run urxvtc? |
74 | First of all, transparency isn't officially supported in rxvt-unicode, |
59 | If you want to start urxvtd automatically whenever you run urxvtc and |
75 | so you are mostly on your own. Do not bug the author about it (but you |
60 | the daemon isn't running yet, use this script: |
76 | may bug everybody else). Also, if you can't get it working consider it a |
|
|
77 | rite of passage: ... and you failed. |
|
|
78 | |
61 | |
79 | Here are four ways to get transparency. Do read the manpage and option |
62 | #!/bin/sh |
80 | descriptions for the programs mentioned and rxvt-unicode. Really, do it! |
63 | urxvtc "$@" |
|
|
64 | if [ $? -eq 2 ]; then |
|
|
65 | urxvtd -q -o -f |
|
|
66 | urxvtc "$@" |
|
|
67 | fi |
81 | |
68 | |
82 | 1. Use inheritPixmap: |
69 | This tries to create a new terminal, and if fails with exit status 2, |
|
|
70 | meaning it couldn't connect to the daemon, it will start the daemon and |
|
|
71 | re-run the command. Subsequent invocations of the script will re-use the |
|
|
72 | existing daemon. |

74 | How do I distinguish whether I'm running rxvt-unicode or a regular |
85 | rxvt -ip -tint red -sh 40 |
75 | xterm? I need this to decide about setting colours etc. |
|
|
76 | The original rxvt and rxvt-unicode always export the variable |
|
|
77 | "COLORTERM", so you can check and see if that is set. Note that several |
|
|
78 | programs, JED, slrn, Midnight Commander automatically check this |
|
|
79 | variable to decide whether or not to use colour. |
86 | |
80 | |
87 | That works. If you think it doesn't, you lack transparency and tinting |
81 | How do I set the correct, full IP address for the DISPLAY variable? |
88 | support, or you are unable to read. |
82 | If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled |
|
|
83 | insecure mode then it is possible to use the following shell script |
|
|
84 | snippets to correctly set the display. If your version of rxvt-unicode |
|
|
85 | wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) |
|
|
86 | then the COLORTERM variable can be used to distinguish rxvt-unicode from |
|
|
87 | a regular xterm. |
89 | |
88 | |
90 | 2. Use a simple pixmap and emulate pseudo-transparency. This enables you |
89 | Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script |
91 | to use effects other than tinting and shading: Just shade/tint/whatever |
90 | snippets: |
92 | your picture with gimp: |
|
|
93 | |
91 | |
94 | convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm |
92 | # Bourne/Korn/POSIX family of shells: |
95 | rxvt -pixmap background.xpm -pe automove-background |
93 | [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know |
|
|
94 | if [ ${TERM:-foo} = xterm ]; then |
|
|
95 | stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not |
|
|
96 | echo -n '^[Z' |
|
|
97 | read term_id |
|
|
98 | stty icanon echo |
|
|
99 | if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then |
|
|
100 | echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string |
|
|
101 | read DISPLAY # set it in our local shell |
|
|
102 | fi |
|
|
103 | fi |
96 | |
104 | |
97 | That works. If you think it doesn't, you lack XPM and Perl support, or |
105 | How do I compile the manual pages on my own? |
98 | you are unable to read. |
106 | You need to have a recent version of perl installed as /usr/bin/perl, |
|
|
107 | one that comes with pod2man, pod2text and pod2xhtml (from Pod::Xhtml). |
|
|
108 | Then go to the doc subdirectory and enter "make alldoc". |
99 | |
109 | |
100 | 3. Use an ARGB visual: |
|
|
101 | |
|
|
102 | rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc |
|
|
103 | |
|
|
104 | This requires XFT support, and the support of your X-server. If that |
|
|
105 | doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't |
|
|
106 | there yet, no matter what they claim. Rxvt-Unicode contains the |
|
|
107 | neccessary bugfixes and workarounds for Xft and Xlib to make it work, |
|
|
108 | but that doesn't mean that your WM has the required kludges in place. |
|
|
109 | |
|
|
110 | 4. Use xcompmgr and let it do the job: |
|
|
111 | |
|
|
112 | xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ |
|
|
113 | -set _NET_WM_WINDOW_OPACITY 0xc0000000 |
|
|
114 | |
|
|
115 | Then click on a window you want to make transparent. Replace 0xc0000000 |
|
|
116 | by other values to change the degree of opacity. If it doesn't work and |
|
|
117 | your server crashes, you got to keep the pieces. |
|
|
118 | |
|

193 | Does it support tabs, can I have a tabbed rxvt-unicode? |
184 | Rendering, Font & Look and Feel Issues |
194 | Beginning with version 7.3, there is a perl extension that implements a |
185 | I can't get transparency working, what am I doing wrong? |
195 | simple tabbed terminal. It is installed by default, so any of these |
186 | First of all, transparency isn't officially supported in rxvt-unicode, |

202 | It will also work fine with tabbing functionality of many window |
196 | Esetroot wallpaper.jpg |
203 | managers or similar tabbing programs, and its embedding-features allow |

|
|
207 | |
198 | |
208 | How do I know which rxvt-unicode version I'm using? |
199 | That works. If you think it doesn't, you lack transparency and tinting |
209 | The version number is displayed with the usage (-h). Also the escape |

203 | |
213 | I am using Debian GNU/Linux and have a problem... |
204 | 2. Use a simple pixmap and emulate pseudo-transparency. This enables you |
214 | The Debian GNU/Linux package of rxvt-unicode in sarge contains large |
205 | to use effects other than tinting and shading: Just shade/tint/whatever |
215 | patches that considerably change the behaviour of rxvt-unicode (but |
206 | your picture with gimp or any other tool: |
216 | unfortunately this notice has been removed). Before reporting a bug to |
|
|
217 | the original rxvt-unicode author please download and install the genuine |
|
|
218 | version (<http://software.schmorp.de#rxvt-unicode>) and try to reproduce |
|
|
219 | the problem. If you cannot, chances are that the problems are specific |
|
|
220 | to Debian GNU/Linux, in which case it should be reported via the Debian |
|
|
221 | Bug Tracking System (use "reportbug" to report the bug). |
|
|
222 | |
207 | |
223 | For other problems that also affect the Debian package, you can and |
208 | convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg |
224 | probably should use the Debian BTS, too, because, after all, it's also a |
209 | urxvt -pixmap "background.jpg;:root" |
225 | bug in the Debian version and it serves as a reminder for other users |
|
|
226 | that might encounter the same issue. |
|
|
227 | |
210 | |
228 | I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation? |
211 | That works. If you think it doesn't, you lack libAfterImage or |
229 | You should build one binary with the default options. configure now |
212 | GDK-PixBuf support, or you are unable to read. |
230 | enables most useful options, and the trend goes to making them |
|
|
231 | runtime-switchable, too, so there is usually no drawback to enbaling |
|
|
232 | them, except higher disk and possibly memory usage. The perl interpreter |
|
|
233 | should be enabled, as important functionality (menus, selection, likely |
|
|
234 | more in the future) depends on it. |
|
|
235 | |
213 | |
236 | You should not overwrite the "perl-ext-common" snd "perl-ext" resources |
214 | 3. Use an ARGB visual: |
237 | system-wide (except maybe with "defaults"). This will result in useful |
|
|
238 | behaviour. If your distribution aims at low memory, add an empty |
|
|
239 | "perl-ext-common" resource to the app-defaults file. This will keep the |
|
|
240 | perl interpreter disabled until the user enables it. |
|
|
241 | |
215 | |
242 | If you can/want build more binaries, I recommend building a minimal one |
216 | urxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc |
243 | with "--disable-everything" (very useful) and a maximal one with |
|
|
244 | "--enable-everything" (less useful, it will be very big due to a lot of |
|
|
245 | encodings built-in that increase download times and are rarely used). |
|
|
246 | |
217 | |
247 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? |
218 | This requires XFT support, and the support of your X-server. If that |
248 | It should be, starting with release 7.1. You are encouraged to properly |
219 | doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't |
249 | install urxvt with privileges necessary for your OS now. |
220 | there yet, no matter what they claim. Rxvt-Unicode contains the |
|
|
221 | necessary bugfixes and workarounds for Xft and Xlib to make it work, but |
|
|
222 | that doesn't mean that your WM has the required kludges in place. |
250 | |
223 | |
251 | When rxvt-unicode detects that it runs setuid or setgid, it will fork |
224 | 4. Use xcompmgr and let it do the job: |
252 | into a helper process for privileged operations (pty handling on some |
|
|
253 | systems, utmp/wtmp/lastlog handling on others) and drop privileges |
|
|
254 | immediately. This is much safer than most other terminals that keep |
|
|
255 | privileges while running (but is more relevant to urxvt, as it contains |
|
|
256 | things as perl interpreters, which might be "helpful" to attackers). |
|
|
257 | |
225 | |
258 | This forking is done as the very first within main(), which is very |
226 | xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ |
259 | early and reduces possible bugs to initialisation code run before |
227 | -set _NET_WM_WINDOW_OPACITY 0xc0000000 |
260 | main(), or things like the dynamic loader of your system, which should |
|
|
261 | result in very little risk. |
|
|
262 | |
228 | |
263 | When I log-in to another system it tells me about missing terminfo data? |
229 | Then click on a window you want to make transparent. Replace 0xc0000000 |
264 | The terminal description used by rxvt-unicode is not as widely available |
230 | by other values to change the degree of opacity. If it doesn't work and |
265 | as that for xterm, or even rxvt (for which the same problem often |
231 | your server crashes, you got to keep the pieces. |
266 | arises). |
|
|
267 | |
232 | |
268 | The correct solution for this problem is to install the terminfo, this |
|
|
269 | 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 different |
|
|
279 | colours and some refresh errors in fullscreen applications. It's a nice |
|
|
280 | quick-and-dirty workaround for rare cases, though. |
|
|
281 | |
|
|
282 | If you always want to do this (and are fine with the consequences) you |
|
|
283 | can either recompile rxvt-unicode with the desired TERM value or use a |
|
|
284 | resource to set it: |
|
|
285 | |
|
|
286 | URxvt.termName: rxvt |
|
|
287 | |
|
|
288 | If you don't plan to use rxvt (quite common...) you could also replace |
|
|
289 | the rxvt terminfo file with the rxvt-unicode one. |
|
|
290 | |
|
|
291 | "tic" outputs some error when compiling the terminfo entry. |
|
|
292 | Most likely it's the empty definition for "enacs=". Just replace it by |
|
|
293 | "enacs=\E[0@" and try again. |
|
|
294 | |
|
|
295 | "bash"'s readline does not work correctly under rxvt. |
|
|
296 | See next entry. |
|
|
297 | |
|
|
298 | I need a termcap file entry. |
|
|
299 | One reason you might want this is that some distributions or operating |
|
|
300 | systems still compile some programs using the long-obsoleted termcap |
|
|
301 | library (Fedora Core's bash is one example) and rely on a termcap entry |
|
|
302 | for "rxvt-unicode". |
|
|
303 | |
|
|
304 | You could use rxvt's termcap entry with resonable results in many cases. |
|
|
305 | You can also create a termcap entry by using terminfo's infocmp program |
|
|
306 | like this: |
|
|
307 | |
|
|
308 | infocmp -C rxvt-unicode |
|
|
309 | |
|
|
310 | Or you could use this termcap entry, generated by the command above: |
|
|
311 | |

|
|
333 | Why does "ls" no longer have coloured output? |
|
|
334 | The "ls" in the GNU coreutils unfortunately doesn't use terminfo to |
|
|
335 | decide wether a terminal has colour, but uses it's own configuration |
|
|
336 | file. Needless to say, "rxvt-unicode" is not in it's default file (among |
|
|
337 | with most other terminals supporting colour). Either add: |
|
|
338 | |
|
|
339 | TERM rxvt-unicode |
|
|
340 | |
|
|
341 | to "/etc/DIR_COLORS" or simply add: |
|
|
342 | |
|
|
343 | alias ls='ls --color=auto' |
|
|
344 | |
|
|
345 | to your ".profile" or ".bashrc". |
|
|
346 | |
|
|
347 | Why doesn't vim/emacs etc. use the 88 colour mode? |
|
|
348 | See next entry. |
|
|
349 | |
|
|
350 | Why doesn't vim/emacs etc. make use of italic? |
|
|
351 | See next entry. |
|
|
352 | |
|
|
353 | Why are the secondary screen-related options not working properly? |
|
|
354 | Make sure you are using "TERM=rxvt-unicode". Some pre-packaged |
|
|
355 | distributions (most notably Debian GNU/Linux) break rxvt-unicode by |
|
|
356 | setting "TERM" to "rxvt", which doesn't have these extra features. |
|
|
357 | Unfortunately, some of these (most notably, again, Debian GNU/Linux) |
|
|
358 | furthermore fail to even install the "rxvt-unicode" terminfo file, so |
|
|
359 | you will need to install it on your own (See the question When I log-in |
|
|
360 | to another system it tells me about missing terminfo data? on how to do |
|
|
361 | this). |
|
|
362 | |
|
|
363 | My numerical keypad acts weird and generates differing output? |
|
|
364 | Some Debian GNUL/Linux users seem to have this problem, although no |
|
|
365 | specific details were reported so far. It is possible that this is |
|
|
366 | caused by the wrong "TERM" setting, although the details of wether and |
|
|
367 | how this can happen are unknown, as "TERM=rxvt" should offer a |
|
|
368 | compatible keymap. See the answer to the previous question, and please |
|
|
369 | report if that helped. |
|
|
370 | |
|
|
371 | Rxvt-unicode does not seem to understand the selected encoding? |
|
|
372 | See next entry. |
|
|
373 | |
|
|
374 | Unicode does not seem to work? |
|
|
375 | If you encounter strange problems like typing an accented character but |
|
|
376 | getting two unrelated other characters or similar, or if program output |
|
|
377 | is subtly garbled, then you should check your locale settings. |
|
|
378 | |
|
|
379 | Rxvt-unicode must be started with the same "LC_CTYPE" setting as the |
|
|
380 | programs. Often rxvt-unicode is started in the "C" locale, while the |
|
|
381 | login script running within the rxvt-unicode window changes the locale |
|
|
382 | to something else, e.g. "en_GB.UTF-8". Needless to say, this is not |
|
|
383 | going to work. |
|
|
384 | |
|
|
385 | The best thing is to fix your startup environment, as you will likely |
|
|
386 | run into other problems. If nothing works you can try this in your |
|
|
387 | .profile. |
|
|
388 | |
|
|
389 | printf '\e]701;%s\007' "$LC_CTYPE" |
|
|
390 | |
|
|
391 | If this doesn't work, then maybe you use a "LC_CTYPE" specification not |
|
|
392 | supported on your systems. Some systems have a "locale" command which |
|
|
393 | displays this (also, "perl -e0" can be used to check locale settings, as |
|
|
394 | it will complain loudly if it cannot set the locale). If it displays |
|
|
395 | something like: |
|
|
396 | |
|
|
397 | locale: Cannot set LC_CTYPE to default locale: ... |
|
|
398 | |
|
|
399 | Then the locale you specified is not supported on your system. |
|
|
400 | |
|
|
401 | If nothing works and you are sure that everything is set correctly then |
|
|
402 | you will need to remember a little known fact: Some programs just don't |
|
|
403 | support locales :( |
|
|
404 | |
|
|
405 | Why do some characters look so much different than others? |
|
|
406 | See next entry. |
|
|
407 | |
|
|
408 | How does rxvt-unicode choose fonts? |
|
|
409 | Most fonts do not contain the full range of Unicode, which is fine. |
|
|
410 | Chances are that the font you (or the admin/package maintainer of your |
|
|
411 | system/os) have specified does not cover all the characters you want to |
|
|
412 | display. |
|
|
413 | |
|
|
414 | rxvt-unicode makes a best-effort try at finding a replacement font. |
|
|
415 | Often the result is fine, but sometimes the chosen font looks |
|
|
416 | bad/ugly/wrong. Some fonts have totally strange characters that don't |
|
|
417 | resemble the correct glyph at all, and rxvt-unicode lacks the artificial |
|
|
418 | intelligence to detect that a specific glyph is wrong: it has to believe |
|
|
419 | the font that the characters it claims to contain indeed look correct. |
|
|
420 | |
|
|
421 | In that case, select a font of your taste and add it to the font list, |
|
|
422 | e.g.: |
|
|
423 | |
|
|
424 | rxvt -fn basefont,font2,font3... |
|
|
425 | |
|
|
426 | When rxvt-unicode sees a character, it will first look at the base font. |
|
|
427 | If the base font does not contain the character, it will go to the next |
|
|
428 | font, and so on. Specifying your own fonts will also speed up this |
|
|
429 | search and use less resources within rxvt-unicode and the X-server. |
|
|
430 | |
|
|
431 | The only limitation is that none of the fonts may be larger than the |
|
|
432 | base font, as the base font defines the terminal character cell size, |
|
|
433 | which must be the same due to the way terminals work. |
|
|
434 | |
|
|
435 | Why do some chinese characters look so different than others? |
|
|
436 | This is because there is a difference between script and language -- |
|
|
437 | rxvt-unicode does not know which language the text that is output is, as |
|
|
438 | it only knows the unicode character codes. If rxvt-unicode first sees a |
|
|
439 | japanese/chinese character, it might choose a japanese font for display. |
|
|
440 | Subsequent japanese characters will use that font. Now, many chinese |
|
|
441 | characters aren't represented in japanese fonts, so when the first |
|
|
442 | non-japanese character comes up, rxvt-unicode will look for a chinese |
|
|
443 | font -- unfortunately at this point, it will still use the japanese font |
|
|
444 | for chinese characters that are also in the japanese font. |
|
|
445 | |
|
|
446 | The workaround is easy: just tag a chinese font at the end of your font |
|
|
447 | list (see the previous question). The key is to view the font list as a |
|
|
448 | preference list: If you expect more japanese, list a japanese font |
|
|
449 | first. If you expect more chinese, put a chinese font first. |
|
|
450 | |
|
|
451 | In the future it might be possible to switch language preferences at |
|
|
452 | runtime (the internal data structure has no problem with using different |
|
|
453 | fonts for the same character at the same time, but no interface for this |
|
|
454 | has been designed yet). |
|
|
455 | |
|
|
456 | Until then, you might get away with switching fonts at runtime (see "Can |
|
|
457 | I switch the fonts at runtime?" later in this document). |
|
|

481 | On Solaris 9, many line-drawing characters are too wide. |
|
|
482 | Seems to be a known bug, read |
|
|
483 | <http://nixdoc.net/files/forum/about34198.html>. Some people use the |
|
|
484 | following ugly workaround to get non-double-wide-characters working: |
|
|
485 | |
|
|
486 | #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x) |
|
|
487 | |
|
|
488 | My Compose (Multi_key) key is no longer working. |
|
|
489 | The most common causes for this are that either your locale is not set |
|
|
490 | correctly, or you specified a preeditStyle that is not supported by your |
|
|
491 | input method. For example, if you specified OverTheSpot and your input |
|
|
492 | method (e.g. the default input method handling Compose keys) does not |
|
|
493 | support this (for instance because it is not visual), then rxvt-unicode |
|
|
494 | will continue without an input method. |
|
|
495 | |
|
|
496 | In this case either do not specify a preeditStyle or specify more than |
|
|
497 | one pre-edit style, such as OverTheSpot,Root,None. |

525 | |
274 | |
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 in |
|
|
528 | your compile environment, or an implementation that implements it, |
|
|
529 | wether it defines the symbol or not. "__STDC_ISO_10646__" requires that |
|
|
530 | wchar_t is represented as unicode. |
|
|
531 | |
|
|
532 | As you might have guessed, FreeBSD does neither define this symobl nor |
|
|
533 | does it support it. Instead, it uses it's own internal representation of |
|
|
534 | wchar_t. This is, of course, completely fine with respect to standards. |
|
|
535 | |
|
|
536 | However, that means rxvt-unicode only works in "POSIX", "ISO-8859-1" and |
|
|
537 | "UTF-8" locales under FreeBSD (which all use Unicode as wchar_t. |
|
|
538 | |
|
|
539 | "__STDC_ISO_10646__" is the only sane way to support multi-language apps |
|
|
540 | in an OS, as using a locale-dependent (and non-standardized) |
|
|
541 | representation of wchar_t makes it impossible to convert between wchar_t |
|
|
542 | (as used by X11 and your applications) and any other encoding without |
|
|
543 | implementing OS-specific-wrappers for each and every locale. There |
|
|
544 | simply are no APIs to convert wchar_t into anything except the current |
|
|
545 | locale encoding. |
|
|
546 | |
|
|
547 | Some applications (such as the formidable mlterm) work around this by |
|
|
548 | carrying their own replacement functions for character set handling with |
|
|
549 | them, and either implementing OS-dependent hacks or doing multiple |
|
|
550 | conversions (which is slow and unreliable in case the OS implements |
|
|
551 | encodings slightly different than the terminal emulator). |
|
|
552 | |
|
|
553 | The rxvt-unicode author insists that the right way to fix this is in the |
|
|
554 | system libraries once and for all, instead of forcing every app to carry |
|
|
555 | complete replacements for them :) |

|
|
561 | How can I use rxvt-unicode under cygwin? |
|
|
562 | rxvt-unicode should compile and run out of the box on cygwin, using the |
|
|
563 | X11 libraries that come with cygwin. libW11 emulation is no longer |
|
|
564 | supported (and makes no sense, either, as it only supported a single |
|
|
565 | font). I recommend starting the X-server in "-multiwindow" or |
|
|
566 | "-rootless" mode instead, which will result in similar look&feel as the |
|
|
567 | old libW11 emulation. |
|
|
568 | |
|
|
569 | At the time of this writing, cygwin didn't seem to support any |
|
|
570 | multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are |
|
|
571 | likely limited to 8-bit encodings. |
|
|
572 | |
|
|
573 | How does rxvt-unicode determine the encoding to use? |
|
|
574 | See next entry. |
|
|
575 | |
|
|
576 | Is there an option to switch encodings? |
|
|
577 | Unlike some other terminals, rxvt-unicode has no encoding switch, and no |
|
|
578 | specific "utf-8" mode, such as xterm. In fact, it doesn't even know |
|
|
579 | about UTF-8 or any other encodings with respect to terminal I/O. |
|
|
580 | |
|
|
581 | The reasons is that there exists a perfectly fine mechanism for |
|
|
582 | selecting the encoding, doing I/O and (most important) communicating |
|
|
583 | this to all applications so everybody agrees on character properties |
|
|
584 | such as width and code number. This mechanism is the *locale*. |
|
|
585 | Applications not using that info will have problems (for example, |
|
|
586 | "xterm" gets the width of characters wrong as it uses it's own, |
|
|
587 | locale-independent table under all locales). |
|
|
588 | |
|
|
589 | Rxvt-unicode uses the "LC_CTYPE" locale category to select encoding. All |
|
|
590 | programs doing the same (that is, most) will automatically agree in the |
|
|
591 | interpretation of characters. |
|
|
592 | |
|
|
593 | Unfortunately, there is no system-independent way to select locales, nor |
|
|
594 | is there a standard on how locale specifiers will look like. |
|
|
595 | |
|
|
596 | On most systems, the content of the "LC_CTYPE" environment variable |
|
|
597 | contains an arbitrary string which corresponds to an already-installed |
|
|
598 | locale. Common names for locales are "en_US.UTF-8", "de_DE.ISO-8859-15", |
|
|
599 | "ja_JP.EUC-JP", i.e. "language_country.encoding", but other forms (i.e. |
|
|
600 | "de" or "german") are also common. |
|
|
601 | |
|
|
602 | Rxvt-unicode ignores all other locale categories, and except for the |
|
|
603 | encoding, ignores country or language-specific settings, i.e. |
|
|
604 | "de_DE.UTF-8" and "ja_JP.UTF-8" are the normally same to rxvt-unicode. |
|
|
605 | |
|
|
606 | If you want to use a specific encoding you have to make sure you start |
|
|
607 | rxvt-unicode with the correct "LC_CTYPE" category. |
|
|
608 | |
|
|
609 | Can I switch locales at runtime? |
|
|
610 | Yes, using an escape sequence. Try something like this, which sets |
|
|
611 | rxvt-unicode's idea of "LC_CTYPE". |
|
|
612 | |
|
|
613 | printf '\e]701;%s\007' ja_JP.SJIS |
|
|
614 | |
|
|
615 | See also the previous answer. |
|
|
616 | |
|
|
617 | Sometimes this capability is rather handy when you want to work in one |
|
|
618 | locale (e.g. "de_DE.UTF-8") but some programs don't support it (e.g. |
|
|
619 | UTF-8). For example, I use this script to start "xjdic", which first |
|
|
620 | switches to a locale supported by xjdic and back later: |
|
|
621 | |
|
|
622 | printf '\e]701;%s\007' ja_JP.SJIS |
|
|
623 | xjdic -js |
|
|
624 | printf '\e]701;%s\007' de_DE.UTF-8 |
|
|
625 | |
|
|
626 | You can also use xterm's "luit" program, which usually works fine, |
|
|
627 | except for some locales where character width differs between program- |
|
|
628 | and rxvt-unicode-locales. |

651 | My input method wants <some encoding> but I want UTF-8, what can I do? |
|
|
652 | You can specify separate locales for the input method and the rest of |
|
|
653 | the terminal, using the resource "imlocale": |
|
|
654 | |
|
|
655 | URxvt.imlocale: ja_JP.EUC-JP |
|
|
656 | |
|
|
657 | Now you can start your terminal with "LC_CTYPE=ja_JP.UTF-8" and still |
|
|
658 | use your input method. Please note, however, that you will not be able |
|
|
659 | to input characters outside "EUC-JP" in a normal way then, as your input |
|
|
660 | method limits you. |
|
|
661 | |
|
|
662 | Rxvt-unicode crashes when the X Input Method changes or exits. |
|
|
663 | Unfortunately, this is unavoidable, as the XIM protocol is racy by |
|
|
664 | design. Applications can avoid some crashes at the expense of memory |
|
|
665 | leaks, and Input Methods can avoid some crashes by careful ordering at |
|
|
666 | exit time. kinput2 (and derived input methods) generally succeeds, while |
|
|
667 | SCIM (or similar input methods) fails. In the end, however, crashes |
|
|
668 | cannot be completely avoided even if both sides cooperate. |
|
|
669 | |
|
|
670 | So the only workaround is not to kill your Input Method Servers. |
|
|
671 | |
|
|
672 | Rxvt-unicode uses gobs of memory, how can I reduce that? |
|
|
673 | Rxvt-unicode tries to obey the rule of not charging you for something |
|
|
674 | you don't use. One thing you should try is to configure out all settings |
|
|
675 | that you don't need, for example, Xft support is a resource hog by |
|
|
676 | design, when used. Compiling it out ensures that no Xft font will be |
|
|
677 | loaded accidentally when rxvt-unicode tries to find a font for your |
|
|
678 | characters. |
|
|
679 | |
|
|
680 | Also, many people (me included) like large windows and even larger |
|
|
681 | scrollback buffers: Without "--enable-unicode3", rxvt-unicode will use 6 |
|
|
682 | bytes per screen cell. For a 160x?? window this amounts to almost a |
|
|
683 | kilobyte per line. A scrollback buffer of 10000 lines will then (if |
|
|
684 | full) use 10 Megabytes of memory. With "--enable-unicode3" it gets |
|
|
685 | worse, as rxvt-unicode then uses 8 bytes per screen cell. |

|
374 | Why do some characters look so much different than others? |
|
|
375 | See next entry. |
|
|
376 | |
|
|
377 | How does rxvt-unicode choose fonts? |
|
|
378 | Most fonts do not contain the full range of Unicode, which is fine. |
|
|
379 | Chances are that the font you (or the admin/package maintainer of your |
|
|
380 | system/os) have specified does not cover all the characters you want to |
|
|
381 | display. |
|
|
382 | |
|
|
383 | rxvt-unicode makes a best-effort try at finding a replacement font. |
|
|
384 | Often the result is fine, but sometimes the chosen font looks |
|
|
385 | bad/ugly/wrong. Some fonts have totally strange characters that don't |
|
|
386 | resemble the correct glyph at all, and rxvt-unicode lacks the artificial |
|
|
387 | intelligence to detect that a specific glyph is wrong: it has to believe |
|
|
388 | the font that the characters it claims to contain indeed look correct. |
|
|
389 | |
|
|
390 | In that case, select a font of your taste and add it to the font list, |
|
|
391 | e.g.: |
|
|
392 | |
|
|
393 | urxvt -fn basefont,font2,font3... |
|
|
394 | |
|
|
395 | When rxvt-unicode sees a character, it will first look at the base font. |
|
|
396 | If the base font does not contain the character, it will go to the next |
|
|
397 | font, and so on. Specifying your own fonts will also speed up this |
|
|
398 | search and use less resources within rxvt-unicode and the X-server. |
|
|
399 | |
|
|
400 | The only limitation is that none of the fonts may be larger than the |
|
|
401 | base font, as the base font defines the terminal character cell size, |
|
|
402 | which must be the same due to the way terminals work. |
|
|
403 | |
|
|
404 | Why do some chinese characters look so different than others? |
|
|
405 | This is because there is a difference between script and language -- |
|
|
406 | rxvt-unicode does not know which language the text that is output is, as |
|
|
407 | it only knows the unicode character codes. If rxvt-unicode first sees a |
|
|
408 | japanese/chinese character, it might choose a japanese font for display. |
|
|
409 | Subsequent japanese characters will use that font. Now, many chinese |
|
|
410 | characters aren't represented in japanese fonts, so when the first |
|
|
411 | non-japanese character comes up, rxvt-unicode will look for a chinese |
|
|
412 | font -- unfortunately at this point, it will still use the japanese font |
|
|
413 | for chinese characters that are also in the japanese font. |
|
|
414 | |
|
|
415 | The workaround is easy: just tag a chinese font at the end of your font |
|
|
416 | list (see the previous question). The key is to view the font list as a |
|
|
417 | preference list: If you expect more japanese, list a japanese font |
|
|
418 | first. If you expect more chinese, put a chinese font first. |
|
|
419 | |
|
|
420 | In the future it might be possible to switch language preferences at |
|
|
421 | runtime (the internal data structure has no problem with using different |
|
|
422 | fonts for the same character at the same time, but no interface for this |
|
|
423 | has been designed yet). |
|
|
424 | |
|
|
425 | Until then, you might get away with switching fonts at runtime (see "Can |
|
|
426 | I switch the fonts at runtime?" later in this document). |

|
428 | How can I make mplayer display video correctly? |
|
|
429 | We are working on it, in the meantime, as a workaround, use something |
|
|
430 | like: |
|
|
431 | |
|
|
432 | urxvt -b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...' |

434 | Keyboard, Mouse & User Interaction |
|
|
435 | The new selection selects pieces that are too big, how can I select single words? |
|
|
436 | If you want to select e.g. alphanumeric words, you can use the following |
|
|
437 | setting: |
|
|
438 | |
|
|
439 | URxvt.selection.pattern-0: ([[:word:]]+) |
|
|
440 | |
|
|
441 | If you click more than twice, the selection will be extended more and |
|
|
442 | more. |
|
|
443 | |
|
|
444 | To get a selection that is very similar to the old code, try this |
|
|
445 | pattern: |
|
|
446 | |
|
|
447 | URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) |
|
|
448 | |
|
|
449 | Please also note that the *LeftClick Shift-LeftClick* combination also |
|
|
450 | selects words like the old code. |
|
|
451 | |
|
|
452 | I don't like the new selection/popups/hotkeys/perl, how do I change/disable it? |
|
|
453 | You can disable the perl extension completely by setting the |
|
|
454 | perl-ext-common resource to the empty string, which also keeps |
|
|
455 | rxvt-unicode from initialising perl, saving memory. |
|
|
456 | |
|
|
457 | If you only want to disable specific features, you first have to |
|
|
458 | identify which perl extension is responsible. For this, read the section |
|
|
459 | PREPACKAGED EXTENSIONS in the urxvtperl(3) manpage. For example, to |
|
|
460 | disable the selection-popup and option-popup, specify this |
|
|
461 | perl-ext-common resource: |
|
|
462 | |
|
|
463 | URxvt.perl-ext-common: default,-selection-popup,-option-popup |
|
|
464 | |
|
|
465 | This will keep the default extensions, but disable the two popup |
|
|
466 | extensions. Some extensions can also be configured, for example, |
|
|
467 | scrollback search mode is triggered by M-s. You can move it to any other |
|
|
468 | combination either by setting the searchable-scrollback resource: |
|
|
469 | |
|
|
470 | URxvt.searchable-scrollback: CM-s |
|
|
471 | |
|
|
472 | The cursor moves when selecting text in the current input line, how do I switch this off? |
|
|
473 | See next entry. |
|
|
474 | |
|
|
475 | During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this? |
|
|
476 | These are caused by the "readline" perl extension. Under normal |
|
|
477 | circumstances, it will move your cursor around when you click into the |
|
|
478 | line that contains it. It tries hard not to do this at the wrong moment, |
|
|
479 | but when running a program that doesn't parse cursor movements or in |
|
|
480 | some cases during rlogin sessions, it fails to detect this properly. |
|
|
481 | |
|
|
482 | You can permanently switch this feature off by disabling the "readline" |
|
|
483 | extension: |
|
|
484 | |
|
|
485 | URxvt.perl-ext-common: default,-readline |
|
|
486 | |
|
|
487 | My numerical keypad acts weird and generates differing output? |
|
|
488 | Some Debian GNUL/Linux users seem to have this problem, although no |
|
|
489 | specific details were reported so far. It is possible that this is |
|
|
490 | caused by the wrong "TERM" setting, although the details of whether and |
|
|
491 | how this can happen are unknown, as "TERM=rxvt" should offer a |
|
|
492 | compatible keymap. See the answer to the previous question, and please |
|
|
493 | report if that helped. |
|
|
494 | |
|
|
495 | My Compose (Multi_key) key is no longer working. |
|
|
496 | The most common causes for this are that either your locale is not set |
|
|
497 | correctly, or you specified a preeditStyle that is not supported by your |
|
|
498 | input method. For example, if you specified OverTheSpot and your input |
|
|
499 | method (e.g. the default input method handling Compose keys) does not |
|
|
500 | support this (for instance because it is not visual), then rxvt-unicode |
|
|
501 | will continue without an input method. |
|
|
502 | |
|
|
503 | In this case either do not specify a preeditStyle or specify more than |
|
|
504 | one pre-edit style, such as OverTheSpot,Root,None. |
|
|
505 | |
|
|
506 | If it still doesn't work, then maybe your input method doesn't support |
|
|
507 | compose sequences - to fall back to the built-in one, make sure you |
|
|
508 | don't specify an input method via "-im" or "XMODIFIERS". |
|
|
509 | |
|
|
510 | I cannot type "Ctrl-Shift-2" to get an ASCII NUL character due to ISO 14755 |
|
|
511 | Either try "Ctrl-2" alone (it often is mapped to ASCII NUL even on |
|
|
512 | international keyboards) or simply use ISO 14755 support to your |
|
|
513 | advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for |
|
|
514 | other codes, too, such as "Ctrl-Shift-1-d" to type the default telnet |
|
|
515 | escape character and so on. |
|
|
516 | |
|
|
517 | Mouse cut/paste suddenly no longer works. |
|
|
518 | Make sure that mouse reporting is actually turned off since killing some |
|
|
519 | editors prematurely may leave the mouse in mouse report mode. I've heard |
|
|
520 | that tcsh may use mouse reporting unless it otherwise specified. A quick |
|
|
521 | check is to see if cut/paste works when the Alt or Shift keys are |
|
|
522 | depressed. |

|

799 | $ rxvt |
|
|

|
|
801 | Toggle with "ESC [ 36 h" / "ESC [ 36 l". |
|
|
802 | |
|
|
803 | For an existing rxvt-unicode: |
|
|
804 | |
|
|
805 | # use Backspace = ^H |

|
806 | $ stty erase ^H |

872 | How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc. |
603 | Terminal Configuration |
873 | rxvt and rxvt-unicode always export the variable "COLORTERM", so you can |
604 | Can I see a typical configuration? |
874 | check and see if that is set. Note that several programs, JED, slrn, |
605 | The default configuration tries to be xterm-like, which I don't like |

606 | that much, but it's least surprise to regular users. |
876 | or not to use color. |
|
|
877 | |
607 | |
878 | How do I set the correct, full IP address for the DISPLAY variable? |
608 | As a rxvt or rxvt-unicode user, you are practically supposed to invest |
879 | If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled |
609 | time into customising your terminal. To get you started, here is the |
880 | insecure mode then it is possible to use the following shell script |
610 | author's .Xdefaults entries, with comments on what they do. It's |
881 | snippets to correctly set the display. If your version of rxvt-unicode |
611 | certainly not *typical*, but what's typical... |
882 | wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) |
|
|
883 | then the COLORTERM variable can be used to distinguish rxvt-unicode from |
|
|
884 | a regular xterm. |

619 | URxvt.preeditType: OnTheSpot,None |
904 | one that comes with pod2man, pod2text and pod2html. Then go to the doc |

907 | My question isn't answered here, can I ask a human? |
621 | This tells rxvt-unicode to use a special locale when communicating with |

633 | This is my perl configuration. The first two set the perl library |
|
|
634 | directory and also tells urxvt to use a large number of extensions. I |
|
|
635 | develop for myself mostly, so I actually use most of the extensions I |
|
|
636 | write. |
|
|
637 | |
|
|
638 | The selection stuff mainly makes the selection perl-error-message aware |
|

|

|

695 | I once thought this is a great idea. |

|
|
706 | |
|
|
707 | I wrote rxvt-unicode to be able to specify fonts exactly. So don't be |
|
|
708 | overwhelmed. A special note: the "9x15bold" mentioned above is actually |
|
|
709 | the version from XFree-3.3, as XFree-4 replaced it by a totally |
|
|
710 | different font (different glyphs for ";" and many other harmless |
|
|
711 | characters), while the second font is actually the "9x15bold" from |
|
|
712 | XFree4/XOrg. The bold version has less chars than the medium version, so |
|
|
713 | I use it for rare characters, too. When editing sources with vim, I use |
|
|
714 | italic for comments and other stuff, which looks quite good with |
|
|
715 | Bitstream Vera anti-aliased. |
|
|
716 | |
|
|
717 | Terminus is a quite bad font (many very wrong glyphs), but for most of |
|
|
718 | my purposes, it works, and gives a different look, as my normal |
|
|
719 | (Non-bold) font is already bold, and I want to see a difference between |
|
|
720 | bold and normal fonts. |
|
|
721 | |
|
|
722 | Please note that I used the "urxvt" instance name and not the "URxvt" |
|
|
723 | class name. That is because I use different configs for different |
|
|
724 | purposes, for example, my IRC window is started with "-name IRC", and |
|
|
725 | uses these defaults: |
|
|
726 | |
|
|
727 | IRC*title: IRC |
|
|
728 | IRC*geometry: 87x12+535+542 |
|
|
729 | IRC*saveLines: 0 |
|
|
730 | IRC*mapAlert: true |
|
|
731 | IRC*font: suxuseuro |
|
|
732 | IRC*boldFont: suxuseuro |
|
|
733 | IRC*colorBD: white |

|
734 | IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007 |
|
|
735 | IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007 |
|
|
736 | |
|
|
737 | "Alt-Ctrl-1" and "Alt-Ctrl-2" switch between two different font sizes. |
|
|
738 | "suxuseuro" allows me to keep an eye (and actually read) stuff while |
|
|
739 | keeping a very small window. If somebody pastes something complicated |
|
|
740 | (e.g. japanese), I temporarily switch to a larger font. |
|
|
741 | |
|
|
742 | The above is all in my ".Xdefaults" (I don't use ".Xresources" nor |
|
|
743 | "xrdb"). I also have some resources in a separate ".Xdefaults-hostname" |
|
|
744 | file for different hosts, for example, on my main desktop, I use: |
|
|
745 | |
|
|
746 | URxvt.keysym.C-M-q: command:\033[3;5;5t |
|
|
747 | URxvt.keysym.C-M-y: command:\033[3;5;606t |
|
|
748 | URxvt.keysym.C-M-e: command:\033[3;1605;5t |
|
|
749 | URxvt.keysym.C-M-c: command:\033[3;1605;606t |
|
|
750 | URxvt.keysym.C-M-p: perl:test |
|
|
751 | |
|
|
752 | The first for keysym definitions allow me to quickly bring some windows |
|
|
753 | in the layout I like most. Ion users might start laughing but will stop |
|
|
754 | immediately when I tell them that I use my own Fvwm2 module for much the |
|
|
755 | same effect as Ion provides, and I only very rarely use the above key |
|
|
756 | combinations :-> |
|
|
757 | |
|
|
758 | Why doesn't rxvt-unicode read my resources? |
|
|
759 | Well, why, indeed? It does, in a way very similar to other X |
|
|
760 | applications. Most importantly, this means that if you or your OS loads |
|
|
761 | resources into the X display (the right way to do it), rxvt-unicode will |
|
|
762 | ignore any resource files in your home directory. It will only read |
|
|
763 | $HOME/.Xdefaults when no resources are attached to the display. |
|
|
764 | |
|
|
765 | If you have or use an $HOME/.Xresources file, chances are that resources |
|
|
766 | are loaded into your X-server. In this case, you have to re-login after |
|
|
767 | every change (or run xrdb -merge $HOME/.Xresources). |
|
|
768 | |
|
|
769 | Also consider the form resources have to use: |
|
|
770 | |
|
|
771 | URxvt.resource: value |
|
|
772 | |
|
|
773 | If you want to use another form (there are lots of different ways of |
|
|
774 | specifying resources), make sure you understand whether and why it |
|
|
775 | works. If unsure, use the form above. |
|
|
776 | |
|
|
777 | When I log-in to another system it tells me about missing terminfo data? |
|
|
778 | The terminal description used by rxvt-unicode is not as widely available |
|
|
779 | as that for xterm, or even rxvt (for which the same problem often |
|
|
780 | arises). |
|
|
781 | |
|
|
782 | The correct solution for this problem is to install the terminfo, this |
|
|
783 | can be done by simply installing rxvt-unicode on the remote system as |
|
|
784 | well (in case you have a nice package manager ready), or you can install |
|
|
785 | the terminfo database manually like this (with ncurses infocmp. works as |
|
|
786 | user and root): |
|
|
787 | |
|
|
788 | REMOTE=remotesystem.domain |
|
|
789 | infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti" |
|
|
790 | |
|
|
791 | One some systems you might need to set $TERMINFO to the full path of |
|
|
792 | $HOME/.terminfo for this to work. |
|
|
793 | |
|
|
794 | If you cannot or do not want to do this, then you can simply set |
|
|
795 | "TERM=rxvt" or even "TERM=xterm", and live with the small number of |
|
|
796 | problems arising, which includes wrong keymapping, less and different |
|
|
797 | colours and some refresh errors in fullscreen applications. It's a nice |
|
|
798 | quick-and-dirty workaround for rare cases, though. |
|
|
799 | |
|
|
800 | If you always want to do this (and are fine with the consequences) you |
|
|
801 | can either recompile rxvt-unicode with the desired TERM value or use a |
|
|
802 | resource to set it: |
|
|
803 | |
|
|
804 | URxvt.termName: rxvt |
|
|
805 | |
|
|
806 | If you don't plan to use rxvt (quite common...) you could also replace |
|
|
807 | the rxvt terminfo file with the rxvt-unicode one and use "TERM=rxvt". |
|
|
808 | |
|
|
809 | nano fails with "Error opening terminal: rxvt-unicode" |
|
|
810 | This exceptionally confusing and useless error message is printed by |
|
|
811 | nano when it can't find the terminfo database. Nothing is wrong with |
|
|
812 | your terminal, read the previous answer for a solution. |
|
|
813 | |
|
|
814 | "tic" outputs some error when compiling the terminfo entry. |
|
|
815 | Most likely it's the empty definition for "enacs=". Just replace it by |
|
|
816 | "enacs=\E[0@" and try again. |
|
|
817 | |
|
|
818 | "bash"'s readline does not work correctly under urxvt. |
|
|
819 | See next entry. |
|
|
820 | |
|
|
821 | I need a termcap file entry. |
|
|
822 | One reason you might want this is that some distributions or operating |
|
|
823 | systems still compile some programs using the long-obsoleted termcap |
|
|
824 | library (Fedora Core's bash is one example) and rely on a termcap entry |
|
|
825 | for "rxvt-unicode". |
|
|
826 | |
|
|
827 | You could use rxvt's termcap entry with reasonable results in many |
|
|
828 | cases. You can also create a termcap entry by using terminfo's infocmp |
|
|
829 | program like this: |
|
|
830 | |
|
|
831 | infocmp -C rxvt-unicode |
|
|
832 | |
|
|
833 | Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap, |
|
|
834 | generated by the command above. |
|
|
835 | |
|
|
836 | Why does "ls" no longer have coloured output? |
|
|
837 | The "ls" in the GNU coreutils unfortunately doesn't use terminfo to |
|
|
838 | decide whether a terminal has colour, but uses its own configuration |
|
|
839 | file. Needless to say, "rxvt-unicode" is not in its default file (among |
|
|
840 | with most other terminals supporting colour). Either add: |
|
|
841 | |
|
|
842 | TERM rxvt-unicode |
|
|
843 | |
|
|
844 | to "/etc/DIR_COLORS" or simply add: |
|
|
845 | |
|
|
846 | alias ls='ls --color=auto' |
|
|
847 | |
|
|
848 | to your ".profile" or ".bashrc". |
|
|
849 | |
|
|
850 | Why doesn't vim/emacs etc. use the 88 colour mode? |
|
|
851 | See next entry. |
|
|
852 | |
|
|
853 | Why doesn't vim/emacs etc. make use of italic? |
|
|
854 | See next entry. |
|
|
855 | |
|
|
856 | Why are the secondary screen-related options not working properly? |
|
|
857 | Make sure you are using "TERM=rxvt-unicode". Some pre-packaged |
|
|
858 | distributions (most notably Debian GNU/Linux) break rxvt-unicode by |
|
|
859 | setting "TERM" to "rxvt", which doesn't have these extra features. |
|
|
860 | Unfortunately, some of these (most notably, again, Debian GNU/Linux) |
|
|
861 | furthermore fail to even install the "rxvt-unicode" terminfo file, so |
|
|
862 | you will need to install it on your own (See the question When I log-in |
|
|
863 | to another system it tells me about missing terminfo data? on how to do |
|
|
864 | this). |
|
|
865 | |
|
|
866 | Encoding / Locale / Input Method Issues |
|
|
867 | Rxvt-unicode does not seem to understand the selected encoding? |
|
|
868 | See next entry. |
|
|
869 | |
|
|
870 | Unicode does not seem to work? |
|
|
871 | If you encounter strange problems like typing an accented character but |
|
|
872 | getting two unrelated other characters or similar, or if program output |
|
|
873 | is subtly garbled, then you should check your locale settings. |
|
|
874 | |
|
|
875 | Rxvt-unicode must be started with the same "LC_CTYPE" setting as the |
|
|
876 | programs running in it. Often rxvt-unicode is started in the "C" locale, |
|
|
877 | while the login script running within the rxvt-unicode window changes |
|
|
878 | the locale to something else, e.g. "en_GB.UTF-8". Needless to say, this |
|
|
879 | is not going to work, and is the most common cause for problems. |
|
|
880 | |
|
|
881 | The best thing is to fix your startup environment, as you will likely |
|
|
882 | run into other problems. If nothing works you can try this in your |
|
|
883 | .profile. |
|
|
884 | |
|
|
885 | printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too |
|
|
886 | |
|
|
887 | If this doesn't work, then maybe you use a "LC_CTYPE" specification not |
|
|
888 | supported on your systems. Some systems have a "locale" command which |
|
|
889 | displays this (also, "perl -e0" can be used to check locale settings, as |
|
|
890 | it will complain loudly if it cannot set the locale). If it displays |
|
|
891 | something like: |
|
|
892 | |
|
|
893 | locale: Cannot set LC_CTYPE to default locale: ... |
|
|
894 | |
|
|
895 | Then the locale you specified is not supported on your system. |
|
|
896 | |
|
|
897 | If nothing works and you are sure that everything is set correctly then |
|
|
898 | you will need to remember a little known fact: Some programs just don't |
|
|
899 | support locales :( |
|
|
900 | |
|
|
901 | How does rxvt-unicode determine the encoding to use? |
|
|
902 | See next entry. |
|
|
903 | |
|
|
904 | Is there an option to switch encodings? |
|
|
905 | Unlike some other terminals, rxvt-unicode has no encoding switch, and no |
|
|
906 | specific "utf-8" mode, such as xterm. In fact, it doesn't even know |
|
|
907 | about UTF-8 or any other encodings with respect to terminal I/O. |
|
|
908 | |
|
|
909 | The reasons is that there exists a perfectly fine mechanism for |
|
|
910 | selecting the encoding, doing I/O and (most important) communicating |
|
|
911 | this to all applications so everybody agrees on character properties |
|
|
912 | such as width and code number. This mechanism is the *locale*. |
|
|
913 | Applications not using that info will have problems (for example, |
|
|
914 | "xterm" gets the width of characters wrong as it uses its own, |
|
|
915 | locale-independent table under all locales). |
|
|
916 | |
|
|
917 | Rxvt-unicode uses the "LC_CTYPE" locale category to select encoding. All |
|
|
918 | programs doing the same (that is, most) will automatically agree in the |
|
|
919 | interpretation of characters. |
|
|
920 | |
|
|
921 | Unfortunately, there is no system-independent way to select locales, nor |
|
|
922 | is there a standard on how locale specifiers will look like. |
|
|
923 | |
|
|
924 | On most systems, the content of the "LC_CTYPE" environment variable |
|
|
925 | contains an arbitrary string which corresponds to an already-installed |
|
|
926 | locale. Common names for locales are "en_US.UTF-8", "de_DE.ISO-8859-15", |
|
|
927 | "ja_JP.EUC-JP", i.e. "language_country.encoding", but other forms (i.e. |
|
|
928 | "de" or "german") are also common. |
|
|
929 | |
|
|
930 | Rxvt-unicode ignores all other locale categories, and except for the |
|
|
931 | encoding, ignores country or language-specific settings, i.e. |
|
|
932 | "de_DE.UTF-8" and "ja_JP.UTF-8" are the normally same to rxvt-unicode. |
|
|
933 | |
|
|
934 | If you want to use a specific encoding you have to make sure you start |
|
|
935 | rxvt-unicode with the correct "LC_CTYPE" category. |
|
|
936 | |
|
|
937 | Can I switch locales at runtime? |
|
|
938 | Yes, using an escape sequence. Try something like this, which sets |
|
|
939 | rxvt-unicode's idea of "LC_CTYPE". |
|
|
940 | |
|
|
941 | printf '\33]701;%s\007' ja_JP.SJIS |
|
|
942 | |
|
|
943 | See also the previous answer. |
|
|
944 | |
|
|
945 | Sometimes this capability is rather handy when you want to work in one |
|
|
946 | locale (e.g. "de_DE.UTF-8") but some programs don't support it (e.g. |
|
|
947 | UTF-8). For example, I use this script to start "xjdic", which first |
|
|
948 | switches to a locale supported by xjdic and back later: |
|
|
949 | |
|
|
950 | printf '\33]701;%s\007' ja_JP.SJIS |
|
|
951 | xjdic -js |
|
|
952 | printf '\33]701;%s\007' de_DE.UTF-8 |
|
|
953 | |
|
|
954 | You can also use xterm's "luit" program, which usually works fine, |
|
|
955 | except for some locales where character width differs between program- |
|
|
956 | and rxvt-unicode-locales. |
|
|
957 | |
|
|
958 | I have problems getting my input method working. |
|
|
959 | Try a search engine, as this is slightly different for every input |
|
|
960 | method server. |
|
|
961 | |
|
|
962 | Here is a checklist: |
|
|
963 | |
|
|
964 | - Make sure your locale *and* the imLocale are supported on your OS. |
|
|
965 | Try "locale -a" or check the documentation for your OS. |
|
|
966 | |
|
|
967 | - Make sure your locale or imLocale matches a locale supported by your |
|
|
968 | XIM. |
|
|
969 | For example, kinput2 does not support UTF-8 locales, you should use |
|
|
970 | "ja_JP.EUC-JP" or equivalent. |
|
|
971 | |
|
|
972 | - Make sure your XIM server is actually running. |
|
|
973 | - Make sure the "XMODIFIERS" environment variable is set correctly when |
|
|
974 | *starting* rxvt-unicode. |
|
|
975 | When you want to use e.g. kinput2, it must be set to "@im=kinput2". |
|
|
976 | For scim, use "@im=SCIM". You can see what input method servers are |
|
|
977 | running with this command: |
|
|
978 | |
|
|
979 | xprop -root XIM_SERVERS |
|
|
980 | |
|
|
981 | |
|
|
982 | |
|
|
983 | My input method wants <some encoding> but I want UTF-8, what can I do? |
|
|
984 | You can specify separate locales for the input method and the rest of |
|
|
985 | the terminal, using the resource "imlocale": |
|
|
986 | |
|
|
987 | URxvt.imlocale: ja_JP.EUC-JP |
|
|
988 | |
|
|
989 | Now you can start your terminal with "LC_CTYPE=ja_JP.UTF-8" and still |
|
|
990 | use your input method. Please note, however, that, depending on your |
|
|
991 | Xlib version, you may not be able to input characters outside "EUC-JP" |
|
|
992 | in a normal way then, as your input method limits you. |
|
|
993 | |
|
|
994 | Rxvt-unicode crashes when the X Input Method changes or exits. |
|
|
995 | Unfortunately, this is unavoidable, as the XIM protocol is racy by |
|
|
996 | design. Applications can avoid some crashes at the expense of memory |
|
|
997 | leaks, and Input Methods can avoid some crashes by careful ordering at |
|
|
998 | exit time. kinput2 (and derived input methods) generally succeeds, while |
|
|
999 | SCIM (or similar input methods) fails. In the end, however, crashes |
|
|
1000 | cannot be completely avoided even if both sides cooperate. |
|
|
1001 | |
|
|
1002 | So the only workaround is not to kill your Input Method Servers. |
|
|
1003 | |
|
|
1004 | Operating Systems / Package Maintaining |
|
|
1005 | I am using Debian GNU/Linux and have a problem... |
|
|
1006 | The Debian GNU/Linux package of rxvt-unicode in sarge contains large |
|
|
1007 | patches that considerably change the behaviour of rxvt-unicode (but |
|
|
1008 | unfortunately this notice has been removed). Before reporting a bug to |
|
|
1009 | the original rxvt-unicode author please download and install the genuine |
|
|
1010 | version (<http://software.schmorp.de/pkg/rxvt-unicode.html>) and try to |

1011 | reproduce the problem. If you cannot, chances are that the problems are |
|
|
1012 | specific to Debian GNU/Linux, in which case it should be reported via |
|
|
1013 | the Debian Bug Tracking System (use "reportbug" to report the bug). |
|
|
1014 | |
|
|
1015 | For other problems that also affect the Debian package, you can and |
|
|
1016 | probably should use the Debian BTS, too, because, after all, it's also a |
|
|
1017 | bug in the Debian version and it serves as a reminder for other users |
|
|
1018 | that might encounter the same issue. |
|
|
1019 | |
|
|
1020 | I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation? |
|
|
1021 | You should build one binary with the default options. configure now |
|
|
1022 | enables most useful options, and the trend goes to making them |
|
|
1023 | runtime-switchable, too, so there is usually no drawback to enabling |
|
|
1024 | them, except higher disk and possibly memory usage. The perl interpreter |
|
|
1025 | should be enabled, as important functionality (menus, selection, likely |
|
|
1026 | more in the future) depends on it. |
|
|
1027 | |
|
|
1028 | You should not overwrite the "perl-ext-common" and "perl-ext" resources |
|
|
1029 | system-wide (except maybe with "defaults"). This will result in useful |
|
|
1030 | behaviour. If your distribution aims at low memory, add an empty |
|
|
1031 | "perl-ext-common" resource to the app-defaults file. This will keep the |
|
|
1032 | perl interpreter disabled until the user enables it. |
|
|
1033 | |
|
|
1034 | If you can/want build more binaries, I recommend building a minimal one |
|
|
1035 | with "--disable-everything" (very useful) and a maximal one with |
|
|
1036 | "--enable-everything" (less useful, it will be very big due to a lot of |
|
|
1037 | encodings built-in that increase download times and are rarely used). |
|
|
1038 | |
|
|
1039 | I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? |
|
|
1040 | It should be, starting with release 7.1. You are encouraged to properly |
|
|
1041 | install urxvt with privileges necessary for your OS now. |
|
|
1042 | |
|
|
1043 | When rxvt-unicode detects that it runs setuid or setgid, it will fork |
|
|
1044 | into a helper process for privileged operations (pty handling on some |
|
|
1045 | systems, utmp/wtmp/lastlog handling on others) and drop privileges |
|
|
1046 | immediately. This is much safer than most other terminals that keep |
|
|
1047 | privileges while running (but is more relevant to urxvt, as it contains |
|
|
1048 | things as perl interpreters, which might be "helpful" to attackers). |
|
|
1049 | |
|
|
1050 | This forking is done as the very first within main(), which is very |
|
|
1051 | early and reduces possible bugs to initialisation code run before |
|
|
1052 | main(), or things like the dynamic loader of your system, which should |
|
|
1053 | result in very little risk. |
|
|
1054 | |
|
|
1055 | I am on FreeBSD and rxvt-unicode does not seem to work at all. |
|
|
1056 | Rxvt-unicode requires the symbol "__STDC_ISO_10646__" to be defined in |
|
|
1057 | your compile environment, or an implementation that implements it, |
|
|
1058 | whether it defines the symbol or not. "__STDC_ISO_10646__" requires that |
|
|
1059 | wchar_t is represented as unicode. |
|
|
1060 | |
|
|
1061 | As you might have guessed, FreeBSD does neither define this symbol nor |
|
|
1062 | does it support it. Instead, it uses its own internal representation of |
|
|
1063 | wchar_t. This is, of course, completely fine with respect to standards. |
|
|
1064 | |
|
|
1065 | However, that means rxvt-unicode only works in "POSIX", "ISO-8859-1" and |
|
|
1066 | "UTF-8" locales under FreeBSD (which all use Unicode as wchar_t). |
|
|
1067 | |
|
|
1068 | "__STDC_ISO_10646__" is the only sane way to support multi-language apps |
|
|
1069 | in an OS, as using a locale-dependent (and non-standardized) |
|
|
1070 | representation of wchar_t makes it impossible to convert between wchar_t |
|
|
1071 | (as used by X11 and your applications) and any other encoding without |
|
|
1072 | implementing OS-specific-wrappers for each and every locale. There |
|
|
1073 | simply are no APIs to convert wchar_t into anything except the current |
|
|
1074 | locale encoding. |
|
|
1075 | |
|
|
1076 | Some applications (such as the formidable mlterm) work around this by |
|
|
1077 | carrying their own replacement functions for character set handling with |
|
|
1078 | them, and either implementing OS-dependent hacks or doing multiple |
|
|
1079 | conversions (which is slow and unreliable in case the OS implements |
|
|
1080 | encodings slightly different than the terminal emulator). |
|
|
1081 | |
|
|
1082 | The rxvt-unicode author insists that the right way to fix this is in the |
|
|
1083 | system libraries once and for all, instead of forcing every app to carry |
|
|
1084 | complete replacements for them :) |
|
|
1085 | |
|
|
1086 | How can I use rxvt-unicode under cygwin? |
|
|
1087 | rxvt-unicode should compile and run out of the box on cygwin, using the |
|
|
1088 | X11 libraries that come with cygwin. libW11 emulation is no longer |
|
|
1089 | supported (and makes no sense, either, as it only supported a single |
|
|
1090 | font). I recommend starting the X-server in "-multiwindow" or |
|
|
1091 | "-rootless" mode instead, which will result in similar look&feel as the |
|
|
1092 | old libW11 emulation. |
|
|
1093 | |
|
|
1094 | At the time of this writing, cygwin didn't seem to support any |
|
|
1095 | multi-byte encodings (you might try "LC_CTYPE=C-UTF-8"), so you are |
|
|
1096 | likely limited to 8-bit encodings. |
|
|
1097 | |
|
|
1098 | Character widths are not correct. |
|
|
1099 | urxvt uses the system wcwidth function to know the information about the |
|
|
1100 | width of characters, so on systems with incorrect locale data you will |
|
|
1101 | likely get bad results. Two notorious examples are Solaris 9, where |
|
|
1102 | single-width characters like U+2514 are reported as double-width, and |
|
|
1103 | Darwin 8, where combining chars are reported having width 1. |
|
|
1104 | |
|
|
1105 | The solution is to upgrade your system or switch to a better one. A |
|
|
1106 | possibly working workaround is to use a wcwidth implementation like |
|
