30single words?
31 31
32Yes. For example, if you want to select alphanumeric words, you can use 32=head3 My question isn't answered here, can I ask a human?
33the following resource:

35 URxvt.selection.pattern-0: ([[:word:]]+) 34Before sending me mail, you could go to IRC: C<irc.freenode.net>,
35channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
36interested in learning about new and exciting problems (but not FAQs :).
36 37
37If you click more than twice, the selection will be extended 38=head3 I use Gentoo, and I have a problem...
38more and more.
39 39
40To get a selection that is very similar to the old code, try this pattern: 40There are three big problems with Gentoo Linux: first of all, most if not
41all Gentoo systems are completely broken (missing or mismatched header
42files, broken compiler etc. are just the tip of the iceberg); secondly,
43the Gentoo maintainer thinks it is a good idea to add broken patches to
44the code; and lastly, it should be called Gentoo GNU/Linux.
41 45
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) 46For these reasons, it is impossible to support rxvt-unicode on
47Gentoo. Problems appearing on Gentoo systems will usually simply be
48ignored unless they can be reproduced on non-Gentoo systems.
43 49
44Please also note that the I<LeftClick Shift-LeftClik> combination also 50=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
45selects words like the old code.
46 51
47=item I don't like the new selection/popups/hotkeys/perl, how do I 52Beginning with version 7.3, there is a perl extension that implements a
48change/disable it? 53simple tabbed terminal. It is installed by default, so any of these should
54give you tabs:
49 55
50You can disable the perl extension completely by setting the 56 @@URXVT_NAME@@ -pe tabbed
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53 57
54If you only want to disable specific features, you first have to 58 URxvt.perl-ext-common: default,tabbed
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59 59
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup 60It will also work fine with tabbing functionality of many window managers
61or similar tabbing programs, and its embedding-features allow it to be
62embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
63the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
64(murxvt) terminal as an example embedding application.
61 65
62This will keep the default extensions, but disable the two popup 66=head3 How do I know which rxvt-unicode version I'm using?
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other combination either by setting the B<searchable-scrollback> resource:
66 67
67 URxvt.searchable-scrollback: CM-s 68The version number is displayed with the usage (-h). Also the escape
69sequence C<ESC [ 8 n> sets the window title to the version number. When
70using the @@URXVT_NAME@@c client, the version displayed is that of the
71daemon.
68 72
73=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
74
75Rxvt-unicode tries to obey the rule of not charging you for something you
76don't use. One thing you should try is to configure out all settings that
77you don't need, for example, Xft support is a resource hog by design,
78when used. Compiling it out ensures that no Xft font will be loaded
79accidentally when rxvt-unicode tries to find a font for your characters.
80
81Also, many people (me included) like large windows and even larger
82scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
836 bytes per screen cell. For a 160x?? window this amounts to almost a
84kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
85use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
86rxvt-unicode then uses 8 bytes per screen cell.
87
88=head3 How can I start @@URXVT_NAME@@d in a race-free way?
89
90Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
91display, create the listening socket and then fork.
92
93=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
94
95If you want to start @@URXVT_NAME@@d automatically whenever you run
96@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
97
98 #!/bin/sh
99 @@URXVT_NAME@@c "$@"
100 if [ $? -eq 2 ]; then
101 @@URXVT_NAME@@d -q -o -f
102 @@URXVT_NAME@@c "$@"
103 fi
104
105This tries to create a new terminal, and if fails with exit status 2,
106meaning it couldn't connect to the daemon, it will start the daemon and
107re-run the command. Subsequent invocations of the script will re-use the
108existing daemon.
109
110=head3 How do I distinguish whether I'm running rxvt-unicode or a regular
111xterm? I need this to decide about setting colours etc.
112
113The original rxvt and rxvt-unicode always export the variable "COLORTERM",
114so you can check and see if that is set. Note that several programs, JED,
115slrn, Midnight Commander automatically check this variable to decide
116whether or not to use colour.
117
118=head3 How do I set the correct, full IP address for the DISPLAY variable?
119
120If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
121insecure mode then it is possible to use the following shell script
122snippets to correctly set the display. If your version of rxvt-unicode
123wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
124the COLORTERM variable can be used to distinguish rxvt-unicode from a
125regular xterm.
126
127Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
128snippets:
129

142
143=head3 How do I compile the manual pages on my own?
144
145You need to have a recent version of perl installed as F</usr/bin/perl>,
146one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
147F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.

145=item Does it support tabs, can I have a tabbed rxvt-unicode?
146 225
147rxvt-unicode does not directly support tabs. It will work fine with 226=head2 Rendering, Font & Look and Feel Issues
148tabbing functionality of many window managers or similar tabbing programs,
149and its embedding-features allow it to be embedded into other programs,
150as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
151module, which features a tabbed urxvt (murxvt) terminal as an example
152embedding application.
153 227
154=item How do I know which rxvt-unicode version I'm using? 228=head3 I can't get transparency working, what am I doing wrong?
155 229
156The version number is displayed with the usage (-h). Also the escape 230First of all, transparency isn't officially supported in rxvt-unicode, so
157sequence C<ESC [ 8 n> sets the window title to the version number. When 231you are mostly on your own. Do not bug the author about it (but you may

159daemon. 233of passage: ... and you failed.
160 234
161=item I am using Debian GNU/Linux and have a problem... 235Here are four ways to get transparency. B<Do> read the manpage and option
236descriptions for the programs mentioned and rxvt-unicode. Really, do it!
162 237
163The Debian GNU/Linux package of rxvt-unicode in sarge contains large 2381. Use transparent mode:
164patches that considerably change the behaviour of rxvt-unicode. Before
165reporting a bug to the original rxvt-unicode author please download and
166install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
167and try to reproduce the problem. If you cannot, chances are that the
168problems are specific to Debian GNU/Linux, in which case it should be
169reported via the Debian Bug Tracking System (use C<reportbug> to report
170the bug).
171 239
172For other problems that also affect the Debian package, you can and 240 Esetroot wallpaper.jpg
173probably should use the Debian BTS, too, because, after all, it's also a 241 @@URXVT_NAME@@ -tr -tint red -sh 40
174bug in the Debian version and it serves as a reminder for other users that
175might encounter the same issue.
176 242
177=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation? 243That works. If you think it doesn't, you lack transparency and tinting
244support, or you are unable to read.
245This method requires that the background-setting program sets the
246_XROOTPMAP_ID or ESETROOT_PMAP_ID property. Compatible programs
247are Esetroot, hsetroot and feh.
178 248
179You should build one binary with the default options. F<configure> 2492. Use a simple pixmap and emulate pseudo-transparency. This enables you
180now enables most useful options, and the trend goes to making them 250to use effects other than tinting and shading: Just shade/tint/whatever
181runtime-switchable, too, so there is usually no drawback to enbaling them, 251your picture with gimp or any other tool:
182except higher disk and possibly memory usage. The perl interpreter should
183be enabled, as important functionality (menus, selection, likely more in
184the future) depends on it.
185 252
186You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources 253 convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
187system-wide (except maybe with C<defaults>). This will result in useful 254 @@URXVT_NAME@@ -pixmap "background.jpg;:root"
188behaviour. If your distribution aims at low memory, add an empty
189C<perl-ext-common> resource to the app-defaults file. This will keep the
190perl interpreter disabled until the user enables it.
191 255
192If you can/want build more binaries, I recommend building a minimal 256That works. If you think it doesn't, you lack libAfterImage or GDK-PixBuf support, or you

194C<--enable-everything> (less useful, it will be very big due to a lot of
195encodings built-in that increase download times and are rarely used).
196 258
197=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? 2593. Use an ARGB visual:
198 260
199Likely not. While I honestly try to make it secure, and am probably not 261 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
200bad at it, I think it is simply unreasonable to expect all of freetype
201+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
202secure. Also, rxvt-unicode disables some options when it detects that it
203runs setuid or setgid, which is not nice. Besides, with the embedded perl
204interpreter the possibility for security problems easily multiplies.
205 262
206Elevated privileges are only required for utmp and pty operations on some 263This requires XFT support, and the support of your X-server. If that
207systems (for example, GNU/Linux doesn't need any extra privileges for 264doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
208ptys, but some need it for utmp support). It is planned to mvoe this into 265there yet, no matter what they claim. Rxvt-Unicode contains the necessary
209a forked handler process, but this is not yet done. 266bugfixes and workarounds for Xft and Xlib to make it work, but that
267doesn't mean that your WM has the required kludges in place.
210 268
211So, while setuid/setgid operation is supported and not a problem on your 2694. Use xcompmgr and let it do the job:
212typical single-user-no-other-logins unix desktop, always remember that
213its an awful lot of code, most of which isn't checked for security issues
214regularly.
215 270
216=item When I log-in to another system it tells me about missing terminfo data? 271 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
272 -set _NET_WM_WINDOW_OPACITY 0xc0000000
217 273
218The terminal description used by rxvt-unicode is not as widely available 274Then click on a window you want to make transparent. Replace C<0xc0000000>
219as that for xterm, or even rxvt (for which the same problem often arises). 275by other values to change the degree of opacity. If it doesn't work and
276your server crashes, you got to keep the pieces.
220 277
221The correct solution for this problem is to install the terminfo, this can
222be done like this (with ncurses' infocmp):
223
224 REMOTE=remotesystem.domain
225 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
226
227... or by installing rxvt-unicode normally on the remote system,
228
229If you cannot or do not want to do this, then you can simply set
230C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
231problems arising, which includes wrong keymapping, less and different
232colours and some refresh errors in fullscreen applications. It's a nice
233quick-and-dirty workaround for rare cases, though.
234
235If you always want to do this (and are fine with the consequences) you
236can either recompile rxvt-unicode with the desired TERM value or use a
237resource to set it:
238
239 URxvt.termName: rxvt
240
241If you don't plan to use B<rxvt> (quite common...) you could also replace
242the rxvt terminfo file with the rxvt-unicode one.
243
244=item C<tic> outputs some error when compiling the terminfo entry.
245
246Most likely it's the empty definition for C<enacs=>. Just replace it by
247C<enacs=\E[0@> and try again.
248
249=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
250
251=item I need a termcap file entry.
252
253One reason you might want this is that some distributions or operating
254systems still compile some programs using the long-obsoleted termcap
255library (Fedora Core's bash is one example) and rely on a termcap entry
256for C<rxvt-unicode>.
257
258You could use rxvt's termcap entry with resonable results in many cases.
259You can also create a termcap entry by using terminfo's infocmp program
260like this:
261
262 infocmp -C rxvt-unicode
263
264Or you could use this termcap entry, generated by the command above:

287=item Why does C<ls> no longer have coloured output?
288
289The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
290decide wether a terminal has colour, but uses it's own configuration

292with most other terminals supporting colour). Either add:
293
294 TERM rxvt-unicode

305
306=item Why are the secondary screen-related options not working properly?
307
308Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
309distributions (most notably Debian GNU/Linux) break rxvt-unicode
310by setting C<TERM> to C<rxvt>, which doesn't have these extra
311features. Unfortunately, some of these (most notably, again, Debian
312GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
313file, so you will need to install it on your own (See the question B<When
314I log-in to another system it tells me about missing terminfo data?> on
315how to do this).
316
317=item My numerical keypad acts weird and generates differing output?
318
319Some Debian GNUL/Linux users seem to have this problem, although no
320specific details were reported so far. It is possible that this is caused
321by the wrong C<TERM> setting, although the details of wether and how
322this can happen are unknown, as C<TERM=rxvt> should offer a compatible
323keymap. See the answer to the previous question, and please report if that
324helped.
325
326=item Rxvt-unicode does not seem to understand the selected encoding?
327
328=item Unicode does not seem to work?
329
330If you encounter strange problems like typing an accented character but
331getting two unrelated other characters or similar, or if program output is
332subtly garbled, then you should check your locale settings.
333
334Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
335programs. Often rxvt-unicode is started in the C<C> locale, while the
336login script running within the rxvt-unicode window changes the locale to
337something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
338
339The best thing is to fix your startup environment, as you will likely run
340into other problems. If nothing works you can try this in your .profile.
341
342 printf '\e]701;%s\007' "$LC_CTYPE"
343
344If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
345supported on your systems. Some systems have a C<locale> command which
346displays this (also, C<perl -e0> can be used to check locale settings, as
347it will complain loudly if it cannot set the locale). If it displays something
348like:
349
350 locale: Cannot set LC_CTYPE to default locale: ...
351
352Then the locale you specified is not supported on your system.
353
354If nothing works and you are sure that everything is set correctly then
355you will need to remember a little known fact: Some programs just don't
356support locales :(
357
358=item Why do some characters look so much different than others?
359
360=item How does rxvt-unicode choose fonts?
361
362Most fonts do not contain the full range of Unicode, which is
363fine. Chances are that the font you (or the admin/package maintainer of
364your system/os) have specified does not cover all the characters you want
365to display.
366
367B<rxvt-unicode> makes a best-effort try at finding a replacement
368font. Often the result is fine, but sometimes the chosen font looks
369bad/ugly/wrong. Some fonts have totally strange characters that don't
370resemble the correct glyph at all, and rxvt-unicode lacks the artificial
371intelligence to detect that a specific glyph is wrong: it has to believe
372the font that the characters it claims to contain indeed look correct.
373
374In that case, select a font of your taste and add it to the font list,
375e.g.:
376
377 @@RXVT_NAME@@ -fn basefont,font2,font3...
378
379When rxvt-unicode sees a character, it will first look at the base
380font. If the base font does not contain the character, it will go to the
381next font, and so on. Specifying your own fonts will also speed up this
382search and use less resources within rxvt-unicode and the X-server.
383
384The only limitation is that none of the fonts may be larger than the base
385font, as the base font defines the terminal character cell size, which
386must be the same due to the way terminals work.
387
388=item Why do some chinese characters look so different than others?
389
390This is because there is a difference between script and language --
391rxvt-unicode does not know which language the text that is output is,
392as it only knows the unicode character codes. If rxvt-unicode first
393sees a japanese/chinese character, it might choose a japanese font for
394display. Subsequent japanese characters will use that font. Now, many
395chinese characters aren't represented in japanese fonts, so when the first
396non-japanese character comes up, rxvt-unicode will look for a chinese font
397-- unfortunately at this point, it will still use the japanese font for
398chinese characters that are also in the japanese font.
399
400The workaround is easy: just tag a chinese font at the end of your font
401list (see the previous question). The key is to view the font list as
402a preference list: If you expect more japanese, list a japanese font
403first. If you expect more chinese, put a chinese font first.
404
405In the future it might be possible to switch language preferences at
406runtime (the internal data structure has no problem with using different
407fonts for the same character at the same time, but no interface for this
408has been designed yet).
409
410Until then, you might get away with switching fonts at runtime (see L<Can
411I switch the fonts at runtime?> later in this document).

447your input method. For example, if you specified B<OverTheSpot> and
448your input method (e.g. the default input method handling Compose keys)
449does not support this (for instance because it is not visual), then
450rxvt-unicode will continue without an input method.
451
452In this case either do not specify a B<preeditStyle> or specify more than

483 320
484=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
485
486Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
487in your compile environment, or an implementation that implements it,
488wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
489B<wchar_t> is represented as unicode.
490
491As you might have guessed, FreeBSD does neither define this symobl nor
492does it support it. Instead, it uses it's own internal representation of
493B<wchar_t>. This is, of course, completely fine with respect to standards.
494
495However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
496C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
497
498C<__STDC_ISO_10646__> is the only sane way to support multi-language
499apps in an OS, as using a locale-dependent (and non-standardized)
500representation of B<wchar_t> makes it impossible to convert between
501B<wchar_t> (as used by X11 and your applications) and any other encoding
502without implementing OS-specific-wrappers for each and every locale. There
503simply are no APIs to convert B<wchar_t> into anything except the current
504locale encoding.
505
506Some applications (such as the formidable B<mlterm>) work around this
507by carrying their own replacement functions for character set handling
508with them, and either implementing OS-dependent hacks or doing multiple
509conversions (which is slow and unreliable in case the OS implements
510encodings slightly different than the terminal emulator).
511
512The rxvt-unicode author insists that the right way to fix this is in the
513system libraries once and for all, instead of forcing every app to carry
514complete replacements for them :)
515

520
521=item How can I use rxvt-unicode under cygwin?
522
523rxvt-unicode should compile and run out of the box on cygwin, using
524the X11 libraries that come with cygwin. libW11 emulation is no
525longer supported (and makes no sense, either, as it only supported a
526single font). I recommend starting the X-server in C<-multiwindow> or
527C<-rootless> mode instead, which will result in similar look&feel as the
528old libW11 emulation.
529
530At the time of this writing, cygwin didn't seem to support any multi-byte
531encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
532to 8-bit encodings.
533
534=item How does rxvt-unicode determine the encoding to use?
535
536=item Is there an option to switch encodings?
537
538Unlike some other terminals, rxvt-unicode has no encoding switch, and no
539specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
540UTF-8 or any other encodings with respect to terminal I/O.
541
542The reasons is that there exists a perfectly fine mechanism for selecting
543the encoding, doing I/O and (most important) communicating this to all
544applications so everybody agrees on character properties such as width
545and code number. This mechanism is the I<locale>. Applications not using
546that info will have problems (for example, C<xterm> gets the width of
547characters wrong as it uses it's own, locale-independent table under all
548locales).
549
550Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
551programs doing the same (that is, most) will automatically agree in the
552interpretation of characters.
553
554Unfortunately, there is no system-independent way to select locales, nor
555is there a standard on how locale specifiers will look like.
556
557On most systems, the content of the C<LC_CTYPE> environment variable
558contains an arbitrary string which corresponds to an already-installed
559locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
560C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
561(i.e. C<de> or C<german>) are also common.
562
563Rxvt-unicode ignores all other locale categories, and except for
564the encoding, ignores country or language-specific settings,
565i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
566rxvt-unicode.
567
568If you want to use a specific encoding you have to make sure you start
569rxvt-unicode with the correct C<LC_CTYPE> category.
570
571=item Can I switch locales at runtime?
572
573Yes, using an escape sequence. Try something like this, which sets
574rxvt-unicode's idea of C<LC_CTYPE>.
575
576 printf '\e]701;%s\007' ja_JP.SJIS
577
578See also the previous answer.
579
580Sometimes this capability is rather handy when you want to work in
581one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
582(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
583first switches to a locale supported by xjdic and back later:
584
585 printf '\e]701;%s\007' ja_JP.SJIS
586 xjdic -js
587 printf '\e]701;%s\007' de_DE.UTF-8
588
589You can also use xterm's C<luit> program, which usually works fine, except
590for some locales where character width differs between program- and
591rxvt-unicode-locales.
592
593=item Can I switch the fonts at runtime? 321=head3 Can I switch the fonts at runtime?

618You can specify separate locales for the input method and the rest of the
619terminal, using the resource C<imlocale>:
620
621 URxvt.imlocale: ja_JP.EUC-JP
622
623Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
624use your input method. Please note, however, that you will not be able to
625input characters outside C<EUC-JP> in a normal way then, as your input
626method limits you.
627
628=item Rxvt-unicode crashes when the X Input Method changes or exits.
629
630Unfortunately, this is unavoidable, as the XIM protocol is racy by
631design. Applications can avoid some crashes at the expense of memory
632leaks, and Input Methods can avoid some crashes by careful ordering at
633exit time. B<kinput2> (and derived input methods) generally succeeds,
634while B<SCIM> (or similar input methods) fails. In the end, however,
635crashes cannot be completely avoided even if both sides cooperate.
636
637So the only workaround is not to kill your Input Method Servers.
638
639=item Rxvt-unicode uses gobs of memory, how can I reduce that?
640
641Rxvt-unicode tries to obey the rule of not charging you for something you
642don't use. One thing you should try is to configure out all settings that
643you don't need, for example, Xft support is a resource hog by design,
644when used. Compiling it out ensures that no Xft font will be loaded
645accidentally when rxvt-unicode tries to find a font for your characters.
646
647Also, many people (me included) like large windows and even larger
648scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
6496 bytes per screen cell. For a 160x?? window this amounts to almost a
650kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
651use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
652rxvt-unicode then uses 8 bytes per screen cell.

429
430=head3 How does rxvt-unicode choose fonts?
431
432Most fonts do not contain the full range of Unicode, which is
433fine. Chances are that the font you (or the admin/package maintainer of
434your system/os) have specified does not cover all the characters you want
435to display.
436
437B<rxvt-unicode> makes a best-effort try at finding a replacement
438font. Often the result is fine, but sometimes the chosen font looks
439bad/ugly/wrong. Some fonts have totally strange characters that don't
440resemble the correct glyph at all, and rxvt-unicode lacks the artificial
441intelligence to detect that a specific glyph is wrong: it has to believe
442the font that the characters it claims to contain indeed look correct.
443
444In that case, select a font of your taste and add it to the font list,
445e.g.:
446
447 @@URXVT_NAME@@ -fn basefont,font2,font3...
448
449When rxvt-unicode sees a character, it will first look at the base
450font. If the base font does not contain the character, it will go to the
451next font, and so on. Specifying your own fonts will also speed up this
452search and use less resources within rxvt-unicode and the X-server.
453
454The only limitation is that none of the fonts may be larger than the base
455font, as the base font defines the terminal character cell size, which
456must be the same due to the way terminals work.
457
458=head3 Why do some chinese characters look so different than others?
459
460This is because there is a difference between script and language --
461rxvt-unicode does not know which language the text that is output is,
462as it only knows the unicode character codes. If rxvt-unicode first
463sees a japanese/chinese character, it might choose a japanese font for
464display. Subsequent japanese characters will use that font. Now, many
465chinese characters aren't represented in japanese fonts, so when the first
466non-japanese character comes up, rxvt-unicode will look for a chinese font
467-- unfortunately at this point, it will still use the japanese font for
468chinese characters that are also in the japanese font.
469
470The workaround is easy: just tag a chinese font at the end of your font
471list (see the previous question). The key is to view the font list as
472a preference list: If you expect more japanese, list a japanese font
473first. If you expect more chinese, put a chinese font first.
474
475In the future it might be possible to switch language preferences at
476runtime (the internal data structure has no problem with using different
477fonts for the same character at the same time, but no interface for this
478has been designed yet).
479
480Until then, you might get away with switching fonts at runtime (see L<Can
481I switch the fonts at runtime?> later in this document).

491
492=head3 The new selection selects pieces that are too big, how can I select single words?
493
494If you want to select e.g. alphanumeric words, you can use the following
495setting:
496
497 URxvt.selection.pattern-0: ([[:word:]]+)
498
499If you click more than twice, the selection will be extended
500more and more.
501
502To get a selection that is very similar to the old code, try this pattern:
503
504 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
505
506Please also note that the I<LeftClick Shift-LeftClick> combination also
507selects words like the old code.
508
509=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
510
511You can disable the perl extension completely by setting the
512B<perl-ext-common> resource to the empty string, which also keeps
513rxvt-unicode from initialising perl, saving memory.
514
515If you only want to disable specific features, you first have to
516identify which perl extension is responsible. For this, read the section
517B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
518example, to disable the B<selection-popup> and B<option-popup>, specify
519this B<perl-ext-common> resource:
520
521 URxvt.perl-ext-common: default,-selection-popup,-option-popup
522
523This will keep the default extensions, but disable the two popup
524extensions. Some extensions can also be configured, for example,
525scrollback search mode is triggered by B<M-s>. You can move it to any
526other combination either by setting the B<searchable-scrollback> resource:

533
534=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
535
536These are caused by the C<readline> perl extension. Under normal
537circumstances, it will move your cursor around when you click into the
538line that contains it. It tries hard not to do this at the wrong moment,
539but when running a program that doesn't parse cursor movements or in some
540cases during rlogin sessions, it fails to detect this properly.
541
542You can permanently switch this feature off by disabling the C<readline>
543extension:
544
545 URxvt.perl-ext-common: default,-readline
546
547=head3 My numerical keypad acts weird and generates differing output?
548
549Some Debian GNUL/Linux users seem to have this problem, although no
550specific details were reported so far. It is possible that this is caused
551by the wrong C<TERM> setting, although the details of whether and how
552this can happen are unknown, as C<TERM=rxvt> should offer a compatible
553keymap. See the answer to the previous question, and please report if that
554helped.
555
556=head3 My Compose (Multi_key) key is no longer working.
557
558The most common causes for this are that either your locale is not set
559correctly, or you specified a B<preeditStyle> that is not supported by
560your input method. For example, if you specified B<OverTheSpot> and
561your input method (e.g. the default input method handling Compose keys)
562does not support this (for instance because it is not visual), then
563rxvt-unicode will continue without an input method.
564
565In this case either do not specify a B<preeditStyle> or specify more than
566one pre-edit style, such as B<OverTheSpot,Root,None>.
567
568If it still doesn't work, then maybe your input method doesn't support
569compose sequences - to fall back to the built-in one, make sure you don't
570specify an input method via C<-im> or C<XMODIFIERS>.
571
572=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755

574Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
575international keyboards) or simply use ISO 14755 support to your
576advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
577codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
578character and so on.

745manually, I can quickly switch them for testing.

776 urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
777
778I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
779overwhelmed. A special note: the C<9x15bold> mentioned above is actually
780the version from XFree-3.3, as XFree-4 replaced it by a totally different
781font (different glyphs for C<;> and many other harmless characters),
782while the second font is actually the C<9x15bold> from XFree4/XOrg. The
783bold version has less chars than the medium version, so I use it for rare
784characters, too. When editing sources with vim, I use italic for comments
785and other stuff, which looks quite good with Bitstream Vera anti-aliased.
786
787Terminus is a quite bad font (many very wrong glyphs), but for most of my
788purposes, it works, and gives a different look, as my normal (Non-bold)
789font is already bold, and I want to see a difference between bold and
790normal fonts.
791
792Please note that I used the C<urxvt> instance name and not the C<URxvt>
793class name. That is because I use different configs for different purposes,
794for example, my IRC window is started with C<-name IRC>, and uses these
795defaults:
796
797 IRC*title: IRC
798 IRC*geometry: 87x12+535+542
799 IRC*saveLines: 0
800 IRC*mapAlert: true
801 IRC*font: suxuseuro
802 IRC*boldFont: suxuseuro
803 IRC*colorBD: white
804 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
805 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
806
807C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
808sizes. C<suxuseuro> allows me to keep an eye (and actually read)
809stuff while keeping a very small window. If somebody pastes something
810complicated (e.g. japanese), I temporarily switch to a larger font.
811
812The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
813C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
814file for different hosts, for example, on my main desktop, I use:
815
816 URxvt.keysym.C-M-q: command:\033[3;5;5t
817 URxvt.keysym.C-M-y: command:\033[3;5;606t
818 URxvt.keysym.C-M-e: command:\033[3;1605;5t
819 URxvt.keysym.C-M-c: command:\033[3;1605;606t
820 URxvt.keysym.C-M-p: perl:test
821
822The first for keysym definitions allow me to quickly bring some windows
823in the layout I like most. Ion users might start laughing but will stop
824immediately when I tell them that I use my own Fvwm2 module for much the
825same effect as Ion provides, and I only very rarely use the above key
826combinations :->
827
828=head3 Why doesn't rxvt-unicode read my resources?
829
830Well, why, indeed? It does, in a way very similar to other X
831applications. Most importantly, this means that if you or your OS loads
832resources into the X display (the right way to do it), rxvt-unicode will
833ignore any resource files in your home directory. It will only read
834F<$HOME/.Xdefaults> when no resources are attached to the display.
835
836If you have or use an F<$HOME/.Xresources> file, chances are that
837resources are loaded into your X-server. In this case, you have to
838re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
839
840Also consider the form resources have to use:
841
842 URxvt.resource: value
843
844If you want to use another form (there are lots of different ways of
845specifying resources), make sure you understand whether and why it
846works. If unsure, use the form above.
847
848=head3 When I log-in to another system it tells me about missing terminfo data?
849
850The terminal description used by rxvt-unicode is not as widely available
851as that for xterm, or even rxvt (for which the same problem often arises).
852
853The correct solution for this problem is to install the terminfo, this can
854be done by simply installing rxvt-unicode on the remote system as well
855(in case you have a nice package manager ready), or you can install the
856terminfo database manually like this (with ncurses infocmp. works as
857user and root):
858
859 REMOTE=remotesystem.domain
860 infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
861
862One some systems you might need to set C<$TERMINFO> to the full path of
863F<$HOME/.terminfo> for this to work.
864
865If you cannot or do not want to do this, then you can simply set
866C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
867problems arising, which includes wrong keymapping, less and different
868colours and some refresh errors in fullscreen applications. It's a nice
869quick-and-dirty workaround for rare cases, though.
870
871If you always want to do this (and are fine with the consequences) you
872can either recompile rxvt-unicode with the desired TERM value or use a
873resource to set it:
874
875 URxvt.termName: rxvt
876
877If you don't plan to use B<rxvt> (quite common...) you could also replace
878the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
879
880=head3 nano fails with "Error opening terminal: rxvt-unicode"
881
882This exceptionally confusing and useless error message is printed by nano
883when it can't find the terminfo database. Nothing is wrong with your
884terminal, read the previous answer for a solution.
885
886=head3 C<tic> outputs some error when compiling the terminfo entry.
887
888Most likely it's the empty definition for C<enacs=>. Just replace it by
889C<enacs=\E[0@> and try again.
890
891=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
892
893See next entry.
894
895=head3 I need a termcap file entry.
896
897One reason you might want this is that some distributions or operating
898systems still compile some programs using the long-obsoleted termcap
899library (Fedora Core's bash is one example) and rely on a termcap entry
900for C<rxvt-unicode>.
901
902You could use rxvt's termcap entry with reasonable results in many cases.
903You can also create a termcap entry by using terminfo's infocmp program
904like this:
905
906 infocmp -C rxvt-unicode
907
908Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap,
909generated by the command above.
910
911=head3 Why does C<ls> no longer have coloured output?
912
913The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
914decide whether a terminal has colour, but uses its own configuration
915file. Needless to say, C<rxvt-unicode> is not in its default file (among
916with most other terminals supporting colour). Either add:
917
918 TERM rxvt-unicode
919
920to C</etc/DIR_COLORS> or simply add:
921
922 alias ls='ls --color=auto'
923
924to your C<.profile> or C<.bashrc>.
925
926=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
927
928See next entry.
929
930=head3 Why doesn't vim/emacs etc. make use of italic?
931
932See next entry.
933
934=head3 Why are the secondary screen-related options not working properly?
935
936Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
937distributions (most notably Debian GNU/Linux) break rxvt-unicode
938by setting C<TERM> to C<rxvt>, which doesn't have these extra
939features. Unfortunately, some of these (most notably, again, Debian
940GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
941file, so you will need to install it on your own (See the question B<When
942I log-in to another system it tells me about missing terminfo data?> on
943how to do this).
944
945
946=head2 Encoding / Locale / Input Method Issues
947
948=head3 Rxvt-unicode does not seem to understand the selected encoding?
949
950See next entry.
951
952=head3 Unicode does not seem to work?
953
954If you encounter strange problems like typing an accented character but
955getting two unrelated other characters or similar, or if program output is
956subtly garbled, then you should check your locale settings.
957
958Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
959programs running in it. Often rxvt-unicode is started in the C<C> locale,
960while the login script running within the rxvt-unicode window changes the
961locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
962not going to work, and is the most common cause for problems.
963
964The best thing is to fix your startup environment, as you will likely run
965into other problems. If nothing works you can try this in your .profile.
966
967 printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
968
969If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
970supported on your systems. Some systems have a C<locale> command which
971displays this (also, C<perl -e0> can be used to check locale settings, as
972it will complain loudly if it cannot set the locale). If it displays something
973like:
974
975 locale: Cannot set LC_CTYPE to default locale: ...
976
977Then the locale you specified is not supported on your system.
978
979If nothing works and you are sure that everything is set correctly then
980you will need to remember a little known fact: Some programs just don't
981support locales :(
982
983=head3 How does rxvt-unicode determine the encoding to use?
984
985See next entry.
986
987=head3 Is there an option to switch encodings?
988
989Unlike some other terminals, rxvt-unicode has no encoding switch, and no
990specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
991UTF-8 or any other encodings with respect to terminal I/O.
992
993The reasons is that there exists a perfectly fine mechanism for selecting
994the encoding, doing I/O and (most important) communicating this to all
995applications so everybody agrees on character properties such as width
996and code number. This mechanism is the I<locale>. Applications not using
997that info will have problems (for example, C<xterm> gets the width of
998characters wrong as it uses its own, locale-independent table under all
999locales).
1000
1001Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1002programs doing the same (that is, most) will automatically agree in the
1003interpretation of characters.
1004
1005Unfortunately, there is no system-independent way to select locales, nor
1006is there a standard on how locale specifiers will look like.
1007
1008On most systems, the content of the C<LC_CTYPE> environment variable
1009contains an arbitrary string which corresponds to an already-installed
1010locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1011C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1012(i.e. C<de> or C<german>) are also common.
1013
1014Rxvt-unicode ignores all other locale categories, and except for
1015the encoding, ignores country or language-specific settings,
1016i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1017rxvt-unicode.
1018
1019If you want to use a specific encoding you have to make sure you start
1020rxvt-unicode with the correct C<LC_CTYPE> category.
1021
1022=head3 Can I switch locales at runtime?
1023
1024Yes, using an escape sequence. Try something like this, which sets
1025rxvt-unicode's idea of C<LC_CTYPE>.
1026
1027 printf '\33]701;%s\007' ja_JP.SJIS
1028
1029See also the previous answer.
1030
1031Sometimes this capability is rather handy when you want to work in
1032one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1033(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1034first switches to a locale supported by xjdic and back later:
1035
1036 printf '\33]701;%s\007' ja_JP.SJIS
1037 xjdic -js
1038 printf '\33]701;%s\007' de_DE.UTF-8
1039
1040You can also use xterm's C<luit> program, which usually works fine, except
1041for some locales where character width differs between program- and
1042rxvt-unicode-locales.
1043
1044=head3 I have problems getting my input method working.
1045
1046Try a search engine, as this is slightly different for every input method server.
1047
1048Here is a checklist:
1049
1050=over 4
1051
1052=item - Make sure your locale I<and> the imLocale are supported on your OS.
1053
1054Try C<locale -a> or check the documentation for your OS.
1055
1056=item - Make sure your locale or imLocale matches a locale supported by your XIM.
1057
1058For example, B<kinput2> does not support UTF-8 locales, you should use
1059C<ja_JP.EUC-JP> or equivalent.
1060
1061=item - Make sure your XIM server is actually running.
1062
1063=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1064
1065When you want to use e.g. B<kinput2>, it must be set to
1066C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1067method servers are running with this command:
1068
1069 xprop -root XIM_SERVERS
1070
1071=item
895 1072
896=back 1073=back
897 1074
1075=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1076
1077You can specify separate locales for the input method and the rest of the
1078terminal, using the resource C<imlocale>:
1079
1080 URxvt.imlocale: ja_JP.EUC-JP
1081
1082Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1083use your input method. Please note, however, that, depending on your Xlib
1084version, you may not be able to input characters outside C<EUC-JP> in a
1085normal way then, as your input method limits you.
1086
1087=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1088
1089Unfortunately, this is unavoidable, as the XIM protocol is racy by
1090design. Applications can avoid some crashes at the expense of memory
1091leaks, and Input Methods can avoid some crashes by careful ordering at
1092exit time. B<kinput2> (and derived input methods) generally succeeds,
1093while B<SCIM> (or similar input methods) fails. In the end, however,
1094crashes cannot be completely avoided even if both sides cooperate.
1095
1096So the only workaround is not to kill your Input Method Servers.
1097
1098
1099=head2 Operating Systems / Package Maintaining
1100
1101=head3 I am using Debian GNU/Linux and have a problem...
1102
1103The Debian GNU/Linux package of rxvt-unicode in sarge contains large
1104patches that considerably change the behaviour of rxvt-unicode (but
1105unfortunately this notice has been removed). Before reporting a bug to
1106the original rxvt-unicode author please download and install the genuine
1107version (L<http://software.schmorp.de/pkg/rxvt-unicode.html>) and try to
1108reproduce the problem. If you cannot, chances are that the problems are
1109specific to Debian GNU/Linux, in which case it should be reported via the
1110Debian Bug Tracking System (use C<reportbug> to report the bug).
1111
1112For other problems that also affect the Debian package, you can and
1113probably should use the Debian BTS, too, because, after all, it's also a
1114bug in the Debian version and it serves as a reminder for other users that
1115might encounter the same issue.
1116
1117=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1118
1119You should build one binary with the default options. F<configure>
1120now enables most useful options, and the trend goes to making them
1121runtime-switchable, too, so there is usually no drawback to enabling them,
1122except higher disk and possibly memory usage. The perl interpreter should
1123be enabled, as important functionality (menus, selection, likely more in
1124the future) depends on it.
1125
1126You should not overwrite the C<perl-ext-common> and C<perl-ext> resources
1127system-wide (except maybe with C<defaults>). This will result in useful
1128behaviour. If your distribution aims at low memory, add an empty
1129C<perl-ext-common> resource to the app-defaults file. This will keep the
1130perl interpreter disabled until the user enables it.
1131
1132If you can/want build more binaries, I recommend building a minimal
1133one with C<--disable-everything> (very useful) and a maximal one with
1134C<--enable-everything> (less useful, it will be very big due to a lot of
1135encodings built-in that increase download times and are rarely used).
1136
1137=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1138
1139It should be, starting with release 7.1. You are encouraged to properly
1140install urxvt with privileges necessary for your OS now.
1141
1142When rxvt-unicode detects that it runs setuid or setgid, it will fork
1143into a helper process for privileged operations (pty handling on some
1144systems, utmp/wtmp/lastlog handling on others) and drop privileges
1145immediately. This is much safer than most other terminals that keep
1146privileges while running (but is more relevant to urxvt, as it contains
1147things as perl interpreters, which might be "helpful" to attackers).
1148
1149This forking is done as the very first within main(), which is very early
1150and reduces possible bugs to initialisation code run before main(), or
1151things like the dynamic loader of your system, which should result in very
1152little risk.
1153
1154=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1155
1156Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1157in your compile environment, or an implementation that implements it,
1158whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1159B<wchar_t> is represented as unicode.
1160
1161As you might have guessed, FreeBSD does neither define this symbol nor
1162does it support it. Instead, it uses its own internal representation of
1163B<wchar_t>. This is, of course, completely fine with respect to standards.
1164
1165However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1166C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>).
1167
1168C<__STDC_ISO_10646__> is the only sane way to support multi-language
1169apps in an OS, as using a locale-dependent (and non-standardized)
1170representation of B<wchar_t> makes it impossible to convert between
1171B<wchar_t> (as used by X11 and your applications) and any other encoding
1172without implementing OS-specific-wrappers for each and every locale. There
1173simply are no APIs to convert B<wchar_t> into anything except the current
1174locale encoding.
1175
1176Some applications (such as the formidable B<mlterm>) work around this
1177by carrying their own replacement functions for character set handling
1178with them, and either implementing OS-dependent hacks or doing multiple
1179conversions (which is slow and unreliable in case the OS implements
1180encodings slightly different than the terminal emulator).
1181
1182The rxvt-unicode author insists that the right way to fix this is in the
1183system libraries once and for all, instead of forcing every app to carry
1184complete replacements for them :)
1185
1186=head3 How can I use rxvt-unicode under cygwin?
1187
1188rxvt-unicode should compile and run out of the box on cygwin, using
1189the X11 libraries that come with cygwin. libW11 emulation is no
1190longer supported (and makes no sense, either, as it only supported a
1191single font). I recommend starting the X-server in C<-multiwindow> or
1192C<-rootless> mode instead, which will result in similar look&feel as the
1193old libW11 emulation.
1194
1195At the time of this writing, cygwin didn't seem to support any multi-byte
1196encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
1197to 8-bit encodings.
1198
1199=head3 Character widths are not correct.
1200
1201urxvt uses the system wcwidth function to know the information about
1202the width of characters, so on systems with incorrect locale data you
1203will likely get bad results. Two notorious examples are Solaris 9,
1204where single-width characters like U+2514 are reported as double-width,
1205and Darwin 8, where combining chars are reported having width 1.
1206
1207The solution is to upgrade your system or switch to a better one. A
1208possibly working workaround is to use a wcwidth implementation like
1209
1210http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

1956Changes all mouse reporting codes to use decimal parameters instead of
1957octets or characters.
1958
1959This mode should be enabled I<before> actually enabling mouse reporting,
1960for semi-obvious reasons.
1961
1962The sequences received for various modes are as follows:
1963
1964 ESC [ M o o o !1005, !1015 (three octets)
1965 ESC [ M c c c 1005, !1015 (three characters)
1966 ESC [ Pm M 1015 (three or more numeric parameters)
1967
1968The first three parameters are C<code>, C<x> and C<y>. Code is the numeric
1969code as for the other modes (but encoded as a decimal number, including
1970the additional offset of 32, so you have to subtract 32 first), C<x> and
1971C<y> are the coordinates (1|1 is the upper left corner, just as with
1972cursor positioning).
1973
1974Example: Shift-Button-1 press at top row, column 80.
1975
1976 ESC [ 37 ; 80 ; 1 M
1977
1978One can use this feature by simply enabling it and then looking for
1979parameters to the C<ESC [ M> reply - if there are any, this mode is
1980active, otherwise one of the old reporting styles is used.
1981
