24=head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
25
26
27=head2 Meta, Features & Commandline Issues
28
29=head3 My question isn't answered here, can I ask a human?
30
31Before sending me mail, you could go to IRC: C<irc.freenode.net>,
32channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
33interested in learning about new and exciting problems (but not FAQs :).
34
35=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
36
37Beginning with version 7.3, there is a perl extension that implements a
38simple tabbed terminal. It is installed by default, so any of these should
39give you tabs:
40
41 @@URXVT_NAME@@ -pe tabbed
42
43 URxvt.perl-ext-common: default,tabbed
44
45It will also work fine with tabbing functionality of many window managers
46or similar tabbing programs, and its embedding-features allow it to be
47embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
48the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
49(murxvt) terminal as an example embedding application.
50
51=head3 How do I know which rxvt-unicode version I'm using?
52
53The version number is displayed with the usage (-h). Also the escape
54sequence C<ESC [ 8 n> sets the window title to the version number. When
55using the @@URXVT_NAME@@c client, the version displayed is that of the
56daemon.
57
58=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
59
60Rxvt-unicode tries to obey the rule of not charging you for something you
61don't use. One thing you should try is to configure out all settings that
62you don't need, for example, Xft support is a resource hog by design,
63when used. Compiling it out ensures that no Xft font will be loaded
64accidentally when rxvt-unicode tries to find a font for your characters.
65
66Also, many people (me included) like large windows and even larger
67scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
686 bytes per screen cell. For a 160x?? window this amounts to almost a
69kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
70use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
71rxvt-unicode then uses 8 bytes per screen cell.
72
73=head3 How can I start @@URXVT_NAME@@d in a race-free way?
74
75Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
76display, create the listening socket and then fork.
77
78=head3 How can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c?
79
80If you want to start @@URXVT_NAME@@d automatically whenever you run
81@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
82
83 #!/bin/sh
84 @@URXVT_NAME@@c "$@"
85 if [ $? -eq 2 ]; then
86 @@URXVT_NAME@@d -q -o -f
87 @@URXVT_NAME@@c "$@"
88 fi
89
90This tries to create a new terminal, and if fails with exit status 2,
91meaning it couldn't connect to the daemon, it will start the daemon and
92re-run the command. Subsequent invocations of the script will re-use the
93existing daemon.
94
95=head3 How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
96
97The original rxvt and rxvt-unicode always export the variable "COLORTERM",
98so you can check and see if that is set. Note that several programs, JED,
99slrn, Midnight Commander automatically check this variable to decide
100whether or not to use color.
101
102=head3 How do I set the correct, full IP address for the DISPLAY variable?
103
104If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
105insecure mode then it is possible to use the following shell script
106snippets to correctly set the display. If your version of rxvt-unicode
107wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
108the COLORTERM variable can be used to distinguish rxvt-unicode from a
109regular xterm.
110
111Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
112snippets:
113
114 # Bourne/Korn/POSIX family of shells:
115 [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
116 if [ ${TERM:-foo} = xterm ]; then
117 stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
118 echo -n '^[Z'

121 if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
122 echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
123 read DISPLAY # set it in our local shell
124 fi
125 fi
126
127=head3 How do I compile the manual pages on my own?
128
129You need to have a recent version of perl installed as F</usr/bin/perl>,
130one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
131the doc subdirectory and enter C<make alldoc>.
132
133=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
134
135I often get asked about this, and I think, no, they didn't cause extra
136bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
137that the urxvt binary is larger (due to some encoding tables always being
138compiled in), but it actually uses less memory (RSS) after startup. Even
139with C<--disable-everything>, this comparison is a bit unfair, as many
140features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
141already in use in this mode.
142
143 text data bss drs rss filename
144 98398 1664 24 15695 1824 rxvt --disable-everything
145 188985 9048 66616 18222 1788 urxvt --disable-everything
146
147When you C<--enable-everything> (which I<is> unfair, as this involves xft
148and full locale/XIM support which are quite bloaty inside libX11 and my
149libc), the two diverge, but not unreasnobaly so.
150
151 text data bss drs rss filename
152 163431 2152 24 20123 2060 rxvt --enable-everything
153 1035683 49680 66648 29096 3680 urxvt --enable-everything
154
155The very large size of the text section is explained by the east-asian
156encoding tables, which, if unused, take up disk space but nothing else
157and can be compiled out unless you rely on X11 core fonts that use those
158encodings. The BSS size comes from the 64k emergency buffer that my c++
159compiler allocates (but of course doesn't use unless you are out of
160memory). Also, using an xft font instead of a core font immediately adds a
161few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
162not used.
163
164Of course, due to every character using two or four bytes instead of one,
165a large scrollback buffer will ultimately make rxvt-unicode use more
166memory.
167
168Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
169still fares rather well. And compared to some monsters like gnome-terminal
170(21152k + extra 4204k in separate processes) or konsole (22200k + extra
17143180k in daemons that stay around after exit, plus half a minute of
172startup time, including the hundreds of warnings it spits out), it fares
173extremely well *g*.
174
175=head3 Why C++, isn't that unportable/bloated/uncool?
176
177Is this a question? :) It comes up very often. The simple answer is: I had
178to write it, and C++ allowed me to write and maintain it in a fraction
179of the time and effort (which is a scarce resource for me). Put even
180shorter: It simply wouldn't exist without C++.
181
182My personal stance on this is that C++ is less portable than C, but in
183the case of rxvt-unicode this hardly matters, as its portability limits
184are defined by things like X11, pseudo terminals, locale support and unix
185domain sockets, which are all less portable than C++ itself.
186
187Regarding the bloat, see the above question: It's easy to write programs
188in C that use gobs of memory, an certainly possible to write programs in
189C++ that don't. C++ also often comes with large libraries, but this is
190not necessarily the case with GCC. Here is what rxvt links against on my
191system with a minimal config:
192
193 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
194 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
195 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
196 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
197
198And here is rxvt-unicode:
199
200 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
201 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
202 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
203 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
204 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
205
206No large bloated libraries (of course, none were linked in statically),
207except maybe libX11 :)
208
209
210=head2 Rendering, Font & Look and Feel Issues
211
212=head3 I can't get transparency working, what am I doing wrong?
213
214First of all, transparency isn't officially supported in rxvt-unicode, so
215you are mostly on your own. Do not bug the author about it (but you may
216bug everybody else). Also, if you can't get it working consider it a rite
217of passage: ... and you failed.
218
219Here are four ways to get transparency. B<Do> read the manpage and option
220descriptions for the programs mentioned and rxvt-unicode. Really, do it!
221
2221. Use inheritPixmap:
223
224 Esetroot wallpaper.jpg
225 @@URXVT_NAME@@ -ip -tint red -sh 40
226
227That works. If you think it doesn't, you lack transparency and tinting
228support, or you are unable to read.
229
2302. Use a simple pixmap and emulate pseudo-transparency. This enables you
231to use effects other than tinting and shading: Just shade/tint/whatever
232your picture with gimp or any other tool:
233
234 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
235 @@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
236
237That works. If you think it doesn't, you lack XPM and Perl support, or you
238are unable to read.
239
2403. Use an ARGB visual:
241
242 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
243
244This requires XFT support, and the support of your X-server. If that
245doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
246there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
247bugfixes and workarounds for Xft and Xlib to make it work, but that
248doesn't mean that your WM has the required kludges in place.
249
2504. Use xcompmgr and let it do the job:
251
252 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
253 -set _NET_WM_WINDOW_OPACITY 0xc0000000
254
255Then click on a window you want to make transparent. Replace C<0xc0000000>
256by other values to change the degree of opacity. If it doesn't work and
257your server crashes, you got to keep the pieces.
258
259=head3 Why does rxvt-unicode sometimes leave pixel droppings?
260
261Most fonts were not designed for terminal use, which means that character
262size varies a lot. A font that is otherwise fine for terminal use might
263contain some characters that are simply too wide. Rxvt-unicode will avoid
264these characters. For characters that are just "a bit" too wide a special
265"careful" rendering mode is used that redraws adjacent characters.
266
267All of this requires that fonts do not lie about character sizes,
268however: Xft fonts often draw glyphs larger than their acclaimed bounding
269box, and rxvt-unicode has no way of detecting this (the correct way is to
270ask for the character bounding box, which unfortunately is wrong in these
271cases).
272
273It's not clear (to me at least), wether this is a bug in Xft, freetype,
274or the respective font. If you encounter this problem you might try using
275the C<-lsp> option to give the font more height. If that doesn't work, you
276might be forced to use a different font.
277
278All of this is not a problem when using X11 core fonts, as their bounding
279box data is correct.
280
281=head3 How can I keep rxvt-unicode from using reverse video so much?
282
283First of all, make sure you are running with the right terminal settings
284(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
285make sure you have specified colours for italic and bold, as otherwise
286rxvt-unicode might use reverse video to simulate the effect:
287
288 URxvt.colorBD: white
289 URxvt.colorIT: green
290
291=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
292
293For some unexplainable reason, some rare programs assume a very weird
294colour palette when confronted with a terminal with more than the standard
2958 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
296these programs not to assume non-ISO colours without very good reasons.
297
298In the meantime, you can either edit your C<rxvt-unicode> terminfo
299definition to only claim 8 colour support or use C<TERM=rxvt>, which will
300fix colours but keep you from using other rxvt-unicode features.
301
302=head3 Can I switch the fonts at runtime?
303
304Yes, using an escape sequence. Try something like this, which has the same
305effect as using the C<-fn> switch, and takes effect immediately:
306
307 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
308
309This is useful if you e.g. work primarily with japanese (and prefer a
310japanese font), but you have to switch to chinese temporarily, where
311japanese fonts would only be in your way.
312
313You can think of this as a kind of manual ISO-2022 switching.
314
315=head3 Why do italic characters look as if clipped?
316
317Many fonts have difficulties with italic characters and hinting. For
318example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
319Mono> completely fails in it's italic face. A workaround might be to
320enable freetype autohinting, i.e. like this:
321
322 URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
323 URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
324
325=head3 Can I speed up Xft rendering somehow?
326
327Yes, the most obvious way to speed it up is to avoid Xft entirely, as
328it is simply slow. If you still want Xft fonts you might try to disable
329antialiasing (by appending C<:antialias=false>), which saves lots of
330memory and also speeds up rendering considerably.
331
332=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
333
334Rxvt-unicode will use whatever you specify as a font. If it needs to
335fall back to it's default font search list it will prefer X11 core
336fonts, because they are small and fast, and then use Xft fonts. It has
337antialiasing disabled for most of them, because the author thinks they
338look best that way.
339
340If you want antialiasing, you have to specify the fonts manually.
341
342=head3 What's with this bold/blink stuff?
343
344If no bold colour is set via C<colorBD:>, bold will invert text using the
345standard foreground colour.
346
347For the standard background colour, blinking will actually make the
348text blink when compiled with C<--enable-blinking>. with standard
349colours. Without C<--enable-blinking>, the blink attribute will be
350ignored.
351
352On ANSI colours, bold/blink attributes are used to set high-intensity
353foreground/background colors.
354
355color0-7 are the low-intensity colors.
356
357color8-15 are the corresponding high-intensity colors.
358
359=head3 I don't like the screen colors. How do I change them?
360
361You can change the screen colors at run-time using F<~/.Xdefaults>
362resources (or as long-options).
363
364Here are values that are supposed to resemble a VGA screen,
365including the murky brown that passes for low-intensity yellow:
366
367 URxvt.color0: #000000
368 URxvt.color1: #A80000
369 URxvt.color2: #00A800
370 URxvt.color3: #A8A800
371 URxvt.color4: #0000A8
372 URxvt.color5: #A800A8
373 URxvt.color6: #00A8A8
374 URxvt.color7: #A8A8A8
375
376 URxvt.color8: #000054
377 URxvt.color9: #FF0054
378 URxvt.color10: #00FF54
379 URxvt.color11: #FFFF54
380 URxvt.color12: #0000FF
381 URxvt.color13: #FF00FF
382 URxvt.color14: #00FFFF
383 URxvt.color15: #FFFFFF
384
385And here is a more complete set of non-standard colors.
386
387 URxvt.cursorColor: #dc74d1
388 URxvt.pointerColor: #dc74d1
389 URxvt.background: #0e0e0e
390 URxvt.foreground: #4ad5e1
391 URxvt.color0: #000000
392 URxvt.color8: #8b8f93
393 URxvt.color1: #dc74d1
394 URxvt.color9: #dc74d1
395 URxvt.color2: #0eb8c7
396 URxvt.color10: #0eb8c7
397 URxvt.color3: #dfe37e
398 URxvt.color11: #dfe37e
399 URxvt.color5: #9e88f0
400 URxvt.color13: #9e88f0
401 URxvt.color6: #73f7ff
402 URxvt.color14: #73f7ff
403 URxvt.color7: #e1dddd
404 URxvt.color15: #e1dddd
405
406They have been described (not by me) as "pretty girly".
407
408=head3 Why do some characters look so much different than others?
409
410See next entry.
411
412=head3 How does rxvt-unicode choose fonts?
413
414Most fonts do not contain the full range of Unicode, which is
415fine. Chances are that the font you (or the admin/package maintainer of
416your system/os) have specified does not cover all the characters you want
417to display.
418
419B<rxvt-unicode> makes a best-effort try at finding a replacement
420font. Often the result is fine, but sometimes the chosen font looks
421bad/ugly/wrong. Some fonts have totally strange characters that don't
422resemble the correct glyph at all, and rxvt-unicode lacks the artificial
423intelligence to detect that a specific glyph is wrong: it has to believe
424the font that the characters it claims to contain indeed look correct.
425
426In that case, select a font of your taste and add it to the font list,
427e.g.:
428
429 @@URXVT_NAME@@ -fn basefont,font2,font3...
430
431When rxvt-unicode sees a character, it will first look at the base
432font. If the base font does not contain the character, it will go to the
433next font, and so on. Specifying your own fonts will also speed up this
434search and use less resources within rxvt-unicode and the X-server.
435
436The only limitation is that none of the fonts may be larger than the base
437font, as the base font defines the terminal character cell size, which
438must be the same due to the way terminals work.
439
440=head3 Why do some chinese characters look so different than others?
441
442This is because there is a difference between script and language --
443rxvt-unicode does not know which language the text that is output is,
444as it only knows the unicode character codes. If rxvt-unicode first
445sees a japanese/chinese character, it might choose a japanese font for
446display. Subsequent japanese characters will use that font. Now, many
447chinese characters aren't represented in japanese fonts, so when the first
448non-japanese character comes up, rxvt-unicode will look for a chinese font
449-- unfortunately at this point, it will still use the japanese font for
450chinese characters that are also in the japanese font.
451
452The workaround is easy: just tag a chinese font at the end of your font
453list (see the previous question). The key is to view the font list as
454a preference list: If you expect more japanese, list a japanese font
455first. If you expect more chinese, put a chinese font first.
456
457In the future it might be possible to switch language preferences at
458runtime (the internal data structure has no problem with using different
459fonts for the same character at the same time, but no interface for this
460has been designed yet).
461
462Until then, you might get away with switching fonts at runtime (see L<Can
463I switch the fonts at runtime?> later in this document).
464
465=head2 Keyboard, Mouse & User Interaction
466
467=head3 The new selection selects pieces that are too big, how can I select single words?
468
469If you want to select e.g. alphanumeric words, you can use the following
470setting:
471
472 URxvt.selection.pattern-0: ([[:word:]]+)
473
474If you click more than twice, the selection will be extended
475more and more.
476
477To get a selection that is very similar to the old code, try this pattern:
478
479 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
480
481Please also note that the I<LeftClick Shift-LeftClik> combination also
482selects words like the old code.
483
484=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
485
486You can disable the perl extension completely by setting the
487B<perl-ext-common> resource to the empty string, which also keeps
488rxvt-unicode from initialising perl, saving memory.
489
490If you only want to disable specific features, you first have to
491identify which perl extension is responsible. For this, read the section
492B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
493example, to disable the B<selection-popup> and B<option-popup>, specify
494this B<perl-ext-common> resource:
495
496 URxvt.perl-ext-common: default,-selection-popup,-option-popup
497
498This will keep the default extensions, but disable the two popup
499extensions. Some extensions can also be configured, for example,
500scrollback search mode is triggered by B<M-s>. You can move it to any
501other combination either by setting the B<searchable-scrollback> resource:
502
503 URxvt.searchable-scrollback: CM-s
504
505=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
506
507See next entry.
508
509=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
510
511These are caused by the C<readline> perl extension. Under normal
512circumstances, it will move your cursor around when you click into the
513line that contains it. It tries hard not to do this at the wrong moment,
514but when running a program that doesn't parse cursor movements or in some
515cases during rlogin sessions, it fails to detect this properly.
516
517You can permamently switch this feature off by disabling the C<readline>
518extension:
519
520 URxvt.perl-ext-common: default,-readline
521
522=head3 My numerical keypad acts weird and generates differing output?
523
524Some Debian GNUL/Linux users seem to have this problem, although no
525specific details were reported so far. It is possible that this is caused
526by the wrong C<TERM> setting, although the details of wether and how
527this can happen are unknown, as C<TERM=rxvt> should offer a compatible
528keymap. See the answer to the previous question, and please report if that
529helped.
530
531=head3 My Compose (Multi_key) key is no longer working.
532
533The most common causes for this are that either your locale is not set
534correctly, or you specified a B<preeditStyle> that is not supported by
535your input method. For example, if you specified B<OverTheSpot> and
536your input method (e.g. the default input method handling Compose keys)
537does not support this (for instance because it is not visual), then
538rxvt-unicode will continue without an input method.
539
540In this case either do not specify a B<preeditStyle> or specify more than
541one pre-edit style, such as B<OverTheSpot,Root,None>.
542
543=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
544
545Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
546international keyboards) or simply use ISO 14755 support to your
547advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
548codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
549character and so on.
550
551=head3 Mouse cut/paste suddenly no longer works.
552
553Make sure that mouse reporting is actually turned off since killing
554some editors prematurely may leave the mouse in mouse report mode. I've
555heard that tcsh may use mouse reporting unless it otherwise specified. A
556quick check is to see if cut/paste works when the Alt or Shift keys are
557depressed.
558
559=head3 What's with the strange Backspace/Delete key behaviour?
560
561Assuming that the physical Backspace key corresponds to the
562BackSpace keysym (not likely for Linux ... see the following
563question) there are two standard values that can be used for
564Backspace: C<^H> and C<^?>.
565
566Historically, either value is correct, but rxvt-unicode adopts the debian
567policy of using C<^?> when unsure, because it's the one only only correct
568choice :).
569
570Rxvt-unicode tries to inherit the current stty settings and uses the value
571of `erase' to guess the value for backspace. If rxvt-unicode wasn't
572started from a terminal (say, from a menu or by remote shell), then the
573system value of `erase', which corresponds to CERASE in <termios.h>, will
574be used (which may not be the same as your stty setting).
575
576For starting a new rxvt-unicode:
577
578 # use Backspace = ^H
579 $ stty erase ^H
580 $ @@URXVT_NAME@@
581
582 # use Backspace = ^?
583 $ stty erase ^?
584 $ @@URXVT_NAME@@
585
586Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
587
588For an existing rxvt-unicode:
589
590 # use Backspace = ^H
591 $ stty erase ^H
592 $ echo -n "^[[36h"
593
594 # use Backspace = ^?
595 $ stty erase ^?
596 $ echo -n "^[[36l"
597
598This helps satisfy some of the Backspace discrepancies that occur, but
599if you use Backspace = C<^H>, make sure that the termcap/terminfo value
600properly reflects that.
601
602The Delete key is a another casualty of the ill-defined Backspace problem.
603To avoid confusion between the Backspace and Delete keys, the Delete
604key has been assigned an escape sequence to match the vt100 for Execute
605(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
606
607Some other Backspace problems:
608
609some editors use termcap/terminfo,
610some editors (vim I'm told) expect Backspace = ^H,
611GNU Emacs (and Emacs-like editors) use ^H for help.
612
613Perhaps someday this will all be resolved in a consistent manner.
614
615=head3 I don't like the key-bindings. How do I change them?
616
617There are some compile-time selections available via configure. Unless
618you have run "configure" with the C<--disable-resources> option you can
619use the `keysym' resource to alter the keystrings associated with keysyms.
620
621Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt>
622
623 URxvt.keysym.Home: \033[1~
624 URxvt.keysym.End: \033[4~
625 URxvt.keysym.C-apostrophe: \033<C-'>
626 URxvt.keysym.C-slash: \033<C-/>
627 URxvt.keysym.C-semicolon: \033<C-;>
628 URxvt.keysym.C-grave: \033<C-`>
629 URxvt.keysym.C-comma: \033<C-,>
630 URxvt.keysym.C-period: \033<C-.>
631 URxvt.keysym.C-0x60: \033<C-`>
632 URxvt.keysym.C-Tab: \033<C-Tab>
633 URxvt.keysym.C-Return: \033<C-Return>
634 URxvt.keysym.S-Return: \033<S-Return>
635 URxvt.keysym.S-space: \033<S-Space>
636 URxvt.keysym.M-Up: \033<M-Up>
637 URxvt.keysym.M-Down: \033<M-Down>
638 URxvt.keysym.M-Left: \033<M-Left>
639 URxvt.keysym.M-Right: \033<M-Right>
640 URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
641 URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
642 URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
643
644See some more examples in the documentation for the B<keysym> resource.
645
646=head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How do I make use of them? For example, the Sun Keyboard type 4 has the following map
647
648 KP_Insert == Insert
649 F22 == Print
650 F27 == Home
651 F29 == Prior
652 F33 == End
653 F35 == Next
654
655Rather than have rxvt-unicode try to accommodate all the various possible
656keyboard mappings, it is better to use `xmodmap' to remap the keys as
657required for your particular machine.
658
659
660
661=head2 Terminal Configuration
662
663=head3 Why doesn't rxvt-unicode read my resources?
664
665Well, why, indeed? It does, in a way very similar to other X
666applications. Most importantly, this means that if you or your OS loads
667resources into the X display (the right way to do it), rxvt-unicode will
668ignore any resource files in your home directory. It will only read
669F<$HOME/.Xdefaults> when no resources are attached to the display.
670
671If you have or use an F<$HOME/.Xresources> file, chances are that
672resources are loaded into your X-server. In this case, you have to
673re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
674
675Also consider the form resources have to use:
676
677 URxvt.resource: value
678
679If you want to use another form (there are lots of different ways of
680specifying resources), make sure you understand wether and why it
681works. If unsure, use the form above.
682
683=head3 When I log-in to another system it tells me about missing terminfo data?
684
685The terminal description used by rxvt-unicode is not as widely available
686as that for xterm, or even rxvt (for which the same problem often arises).
687
688The correct solution for this problem is to install the terminfo, this can
689be done like this (with ncurses' infocmp):
690
691 REMOTE=remotesystem.domain
692 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
693
694... or by installing rxvt-unicode normally on the remote system,
695
696If you cannot or do not want to do this, then you can simply set
697C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
698problems arising, which includes wrong keymapping, less and different
699colours and some refresh errors in fullscreen applications. It's a nice
700quick-and-dirty workaround for rare cases, though.
701
702If you always want to do this (and are fine with the consequences) you
703can either recompile rxvt-unicode with the desired TERM value or use a
704resource to set it:
705
706 URxvt.termName: rxvt
707
708If you don't plan to use B<rxvt> (quite common...) you could also replace
709the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
710
711=head3 C<tic> outputs some error when compiling the terminfo entry.
712
713Most likely it's the empty definition for C<enacs=>. Just replace it by
714C<enacs=\E[0@> and try again.
715
716=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
717
718See next entry.
719
720=head3 I need a termcap file entry.
721
722One reason you might want this is that some distributions or operating
723systems still compile some programs using the long-obsoleted termcap
724library (Fedora Core's bash is one example) and rely on a termcap entry
725for C<rxvt-unicode>.
726
727You could use rxvt's termcap entry with resonable results in many cases.
728You can also create a termcap entry by using terminfo's infocmp program
729like this:
730
731 infocmp -C rxvt-unicode
732
733Or you could use this termcap entry, generated by the command above:
734

755
756=head3 Why does C<ls> no longer have coloured output?
757
758The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
759decide wether a terminal has colour, but uses it's own configuration
760file. Needless to say, C<rxvt-unicode> is not in it's default file (among
761with most other terminals supporting colour). Either add:
762
763 TERM rxvt-unicode
764
765to C</etc/DIR_COLORS> or simply add:
766
767 alias ls='ls --color=auto'
768
769to your C<.profile> or C<.bashrc>.
770
771=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
772
773See next entry.
774
775=head3 Why doesn't vim/emacs etc. make use of italic?
776
777See next entry.
778
779=head3 Why are the secondary screen-related options not working properly?
780
781Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
782distributions (most notably Debian GNU/Linux) break rxvt-unicode
783by setting C<TERM> to C<rxvt>, which doesn't have these extra
784features. Unfortunately, some of these (most notably, again, Debian
785GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
786file, so you will need to install it on your own (See the question B<When
787I log-in to another system it tells me about missing terminfo data?> on
788how to do this).
789
790
791=head2 Encoding / Locale / Input Method Issues
792
793=head3 Rxvt-unicode does not seem to understand the selected encoding?
794
795See next entry.
796
797=head3 Unicode does not seem to work?
798
799If you encounter strange problems like typing an accented character but
800getting two unrelated other characters or similar, or if program output is
801subtly garbled, then you should check your locale settings.
802
803Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
804programs. Often rxvt-unicode is started in the C<C> locale, while the
805login script running within the rxvt-unicode window changes the locale to
806something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
807
808The best thing is to fix your startup environment, as you will likely run
809into other problems. If nothing works you can try this in your .profile.
810
811 printf '\e]701;%s\007' "$LC_CTYPE"
812
813If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
814supported on your systems. Some systems have a C<locale> command which
815displays this (also, C<perl -e0> can be used to check locale settings, as
816it will complain loudly if it cannot set the locale). If it displays something
817like:
818
819 locale: Cannot set LC_CTYPE to default locale: ...
820
821Then the locale you specified is not supported on your system.
822
823If nothing works and you are sure that everything is set correctly then
824you will need to remember a little known fact: Some programs just don't
825support locales :(
826
827=head3 How does rxvt-unicode determine the encoding to use?
828
829See next entry.
830
831=head3 Is there an option to switch encodings?
832
833Unlike some other terminals, rxvt-unicode has no encoding switch, and no
834specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
835UTF-8 or any other encodings with respect to terminal I/O.
836
837The reasons is that there exists a perfectly fine mechanism for selecting
838the encoding, doing I/O and (most important) communicating this to all
839applications so everybody agrees on character properties such as width
840and code number. This mechanism is the I<locale>. Applications not using
841that info will have problems (for example, C<xterm> gets the width of
842characters wrong as it uses it's own, locale-independent table under all
843locales).
844
845Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
846programs doing the same (that is, most) will automatically agree in the
847interpretation of characters.
848
849Unfortunately, there is no system-independent way to select locales, nor
850is there a standard on how locale specifiers will look like.
851
852On most systems, the content of the C<LC_CTYPE> environment variable
853contains an arbitrary string which corresponds to an already-installed
854locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
855C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
856(i.e. C<de> or C<german>) are also common.
857
858Rxvt-unicode ignores all other locale categories, and except for
859the encoding, ignores country or language-specific settings,
860i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
861rxvt-unicode.
862
863If you want to use a specific encoding you have to make sure you start
864rxvt-unicode with the correct C<LC_CTYPE> category.
865
866=head3 Can I switch locales at runtime?
867
868Yes, using an escape sequence. Try something like this, which sets
869rxvt-unicode's idea of C<LC_CTYPE>.
870
871 printf '\e]701;%s\007' ja_JP.SJIS
872
873See also the previous answer.
874
875Sometimes this capability is rather handy when you want to work in
876one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
877(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
878first switches to a locale supported by xjdic and back later:
879
880 printf '\e]701;%s\007' ja_JP.SJIS
881 xjdic -js
882 printf '\e]701;%s\007' de_DE.UTF-8
883
884You can also use xterm's C<luit> program, which usually works fine, except
885for some locales where character width differs between program- and
886rxvt-unicode-locales.
887
888=head3 I have problems getting my input method working.
889
890Try a search engine, as this is slightly different for every input method server.
891
892Here is a checklist:
893
894=over 4
895
896=item - Make sure your locale I<and> the imLocale are supported on your OS.
897
898Try C<locale -a> or check the documentation for your OS.
899
900=item - Make sure your locale or imLocale matches a locale supported by your XIM.
901
902For example, B<kinput2> does not support UTF-8 locales, you should use
903C<ja_JP.EUC-JP> or equivalent.
904
905=item - Make sure your XIM server is actually running.
906
907=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
908
909When you want to use e.g. B<kinput2>, it must be set to
910C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. Youc an see what input
911method servers are running with this command:
912
913 xprop -root XIM_SERVERS
914
915=item
916
917=back
918
919=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
920
921You can specify separate locales for the input method and the rest of the
922terminal, using the resource C<imlocale>:
923
924 URxvt.imlocale: ja_JP.EUC-JP
925
926Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
927use your input method. Please note, however, that, depending on your Xlib
928version, you may not be able to input characters outside C<EUC-JP> in a
929normal way then, as your input method limits you.
930
931=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
932
933Unfortunately, this is unavoidable, as the XIM protocol is racy by
934design. Applications can avoid some crashes at the expense of memory
935leaks, and Input Methods can avoid some crashes by careful ordering at
936exit time. B<kinput2> (and derived input methods) generally succeeds,
937while B<SCIM> (or similar input methods) fails. In the end, however,
938crashes cannot be completely avoided even if both sides cooperate.
939
940So the only workaround is not to kill your Input Method Servers.
941
942
943=head2 Operating Systems / Package Maintaining
944
945=head3 I am using Debian GNU/Linux and have a problem...
946
947The Debian GNU/Linux package of rxvt-unicode in sarge contains large
948patches that considerably change the behaviour of rxvt-unicode (but
949unfortunately this notice has been removed). Before reporting a bug to
950the original rxvt-unicode author please download and install the genuine
951version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
952the problem. If you cannot, chances are that the problems are specific to
953Debian GNU/Linux, in which case it should be reported via the Debian Bug
954Tracking System (use C<reportbug> to report the bug).
955
956For other problems that also affect the Debian package, you can and
957probably should use the Debian BTS, too, because, after all, it's also a
958bug in the Debian version and it serves as a reminder for other users that
959might encounter the same issue.
960
961=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
962
963You should build one binary with the default options. F<configure>
964now enables most useful options, and the trend goes to making them
965runtime-switchable, too, so there is usually no drawback to enbaling them,
966except higher disk and possibly memory usage. The perl interpreter should
967be enabled, as important functionality (menus, selection, likely more in
968the future) depends on it.
969
970You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
971system-wide (except maybe with C<defaults>). This will result in useful
972behaviour. If your distribution aims at low memory, add an empty
973C<perl-ext-common> resource to the app-defaults file. This will keep the
974perl interpreter disabled until the user enables it.
975
976If you can/want build more binaries, I recommend building a minimal
977one with C<--disable-everything> (very useful) and a maximal one with
978C<--enable-everything> (less useful, it will be very big due to a lot of
979encodings built-in that increase download times and are rarely used).
980
981=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
982
983It should be, starting with release 7.1. You are encouraged to properly
984install urxvt with privileges necessary for your OS now.
985
986When rxvt-unicode detects that it runs setuid or setgid, it will fork
987into a helper process for privileged operations (pty handling on some
988systems, utmp/wtmp/lastlog handling on others) and drop privileges
989immediately. This is much safer than most other terminals that keep
990privileges while running (but is more relevant to urxvt, as it contains
991things as perl interpreters, which might be "helpful" to attackers).
992
993This forking is done as the very first within main(), which is very early
994and reduces possible bugs to initialisation code run before main(), or
995things like the dynamic loader of your system, which should result in very
996little risk.
997
998=head3 On Solaris 9, many line-drawing characters are too wide.
999
1000Seems to be a known bug, read
1001L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
1002following ugly workaround to get non-double-wide-characters working:
1003
1004 #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
1005
1006=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1007
1008Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1009in your compile environment, or an implementation that implements it,
1010wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1011B<wchar_t> is represented as unicode.
1012
1013As you might have guessed, FreeBSD does neither define this symobl nor
1014does it support it. Instead, it uses it's own internal representation of
1015B<wchar_t>. This is, of course, completely fine with respect to standards.
1016
1017However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1018C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
1019
1020C<__STDC_ISO_10646__> is the only sane way to support multi-language
1021apps in an OS, as using a locale-dependent (and non-standardized)
1022representation of B<wchar_t> makes it impossible to convert between
1023B<wchar_t> (as used by X11 and your applications) and any other encoding
1024without implementing OS-specific-wrappers for each and every locale. There
1025simply are no APIs to convert B<wchar_t> into anything except the current
1026locale encoding.
1027
1028Some applications (such as the formidable B<mlterm>) work around this
1029by carrying their own replacement functions for character set handling
1030with them, and either implementing OS-dependent hacks or doing multiple
1031conversions (which is slow and unreliable in case the OS implements
1032encodings slightly different than the terminal emulator).
1033
1034The rxvt-unicode author insists that the right way to fix this is in the
1035system libraries once and for all, instead of forcing every app to carry
1036complete replacements for them :)
1037
1038=head3 I use Solaris 9 and it doesn't compile/work/etc.
1039
1040Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
1041problems with C<wcwidth> and a compile problem.
1042
1043=head3 How can I use rxvt-unicode under cygwin?
1044
1045rxvt-unicode should compile and run out of the box on cygwin, using
1046the X11 libraries that come with cygwin. libW11 emulation is no
1047longer supported (and makes no sense, either, as it only supported a
1048single font). I recommend starting the X-server in C<-multiwindow> or
1049C<-rootless> mode instead, which will result in similar look&feel as the
1050old libW11 emulation.
1051
1052At the time of this writing, cygwin didn't seem to support any multi-byte
1053encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
1054to 8-bit encodings.

760
761B<< The exact syntax used is I<almost> solidified. >>
762In the menus, B<DON'T> try to use menuBar commands that add or remove a
763menuBar.
764
765Note that in all of the commands, the B<< I</path/> >> I<cannot> be
766omitted: use B<./> to specify a menu relative to the current menu.
767
768=head2 Overview of menuBar operation
769
770For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
771of C<Pt> can be used for a variety of tasks:
772
773At the top level is the current menuBar which is a member of a circular
774linked-list of other such menuBars.
775
776The menuBar acts as a parent for the various drop-down menus, which in
777turn, may have labels, separator lines, menuItems and subMenus.
778
779The menuItems are the useful bits: you can use them to mimic keyboard
780input or even to send text or escape sequences back to rxvt.
781
782The menuBar syntax is intended to provide a simple yet robust method of
783constructing and manipulating menus and navigating through the
784menuBars.
785
786The first step is to use the tag B<< [menu:I<name>] >> which creates
787the menuBar called I<name> and allows access. You may now or menus,
788subMenus, and menuItems. Finally, use the tag B<[done]> to set the
789menuBar access as B<readonly> to prevent accidental corruption of the
790menus. To re-access the current menuBar for alterations, use the tag
791B<[menu]>, make the alterations and then use B<[done]>
792

801access the named menuBar for creation or alteration. If a new menuBar
802is created, it is called I<name> (max of 15 chars) and the current
803menuBar is pushed onto the stack
804
805=item B<[menu]>
806
807access the current menuBar for alteration
808
809=item B<< [title:+I<string>] >>
810
811set the current menuBar's title to I<string>, which may contain the
812following format specifiers:
813B<%%> : literal B<%> character
814B<%n> : rxvt name (as per the B<-name> command-line option)
815B<%v> : rxvt version
816
817=item B<[done]>
818
819set menuBar access as B<readonly>.
820End-of-file tag for B<< [read:+I<file>] >> operations.
821
822=item B<< [read:+I<file>] >>
823
824read menu commands directly from I<file> (extension ".menu" will be
825appended if required.) Start reading at a line with B<[menu]> or B<<
826[menu:+I<name> >> and continuing until B<[done]> is encountered.
827
828Blank and comment lines (starting with B<#>) are ignored. Actually,
829since any invalid menu commands are also ignored, almost anything could
830be construed as a comment line, but this may be tightened up in the
831future ... so don't count on it!.
832
833=item B<< [read:+I<file>;+I<name>] >>
834
835The same as B<< [read:+I<file>] >>, but start reading at a line with

947

951
952B<\a \b \E \e \n \r \t \octal>
953
954=item or in control-character notation:
955
956B<^@, ^A .. ^Z .. ^_, ^?>
957
958=back
959
960To send a string starting with a B<NUL> (B<^@>) character to the
961program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
962the first of which will be stripped off and the balance directed to the
963program. Otherwise if I<action> begins with B<NUL> followed by
964non-+B<NUL> characters, the leading B<NUL> is stripped off and the
965balance is sent back to rxvt.
966
967As a convenience for the many Emacs-type editors, I<action> may start
968with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
969appended if missed from B<M-x> commands.
970
971As a convenience for issuing XTerm B<ESC]> sequences from a menubar (or
972quick arrow), a B<BEL> (B<^G>) will be appended if needed.
973
974=over 4
975
976=item For example,
977
978B<M-xapropos> is equivalent to B<\Exapropos\r>
979

981
982B<\E]703;mona;100> is equivalent to B<\E]703;mona;100\a>
983
984=back
985
986The option B<< {I<right-rtext>} >> will be right-justified. In the
987absence of a specified action, this text will be used as the I<action>
988as well.
989

993
994B</File/{Open}{^X^F}> is equivalent to B</File/{Open}{^X^F} ^X^F>

997
998The left label I<is> necessary, since it's used for matching, but
999implicitly hiding the left label (by using same name for both left and
1000right labels), or explicitly hiding the left label (by preceeding it
1001with a dot), makes it possible to have right-justified text only.

1046
1047The menus also provide a hook for I<quick arrows> to provide easier
1048user access. If nothing has been explicitly set, the default is to
1049emulate the curror keys. The syntax permits each arrow to be altered
1050individually or all four at once without re-entering their common
1051beginning/end text. For example, to explicitly associate cursor actions
1052with the arrows, any of the following forms could be used:
