170.IX Subsection "Does it support tabs, can I have a tabbed rxvt-unicode?"
171.PP
172Beginning with version 7.3, there is a perl extension that implements a
173simple tabbed terminal. It is installed by default, so any of these should
174give you tabs:

169If you click more than twice, the selection will be extended
170more and more.
171.PP
172To get a selection that is very similar to the old code, try this pattern:

183\&\fBperl-ext-common\fR resource to the empty string, which also keeps
184rxvt-unicode from initialising perl, saving memory.
185.PP 189.PP
186If you only want to disable specific features, you first have to 190\fIHow do I know which rxvt-unicode version I'm using?\fR
187identify which perl extension is responsible. For this, read the section 191.IX Subsection "How do I know which rxvt-unicode version I'm using?"
188\&\fB\s-1PREPACKAGED\s0 \s-1EXTENSIONS\s0\fR in the @@RXVT_NAME@@\fIperl\fR\|(3) manpage. For
189example, to disable the \fBselection-popup\fR and \fBoption-popup\fR, specify
190this \fBperl-ext-common\fR resource:
191.PP 192.PP
193The version number is displayed with the usage (\-h). Also the escape
194sequence \f(CW\*(C`ESC [ 8 n\*(C'\fR sets the window title to the version number. When
195using the @@URXVT_NAME@@c client, the version displayed is that of the
196daemon.
197.PP
198\fIRxvt-unicode uses gobs of memory, how can I reduce that?\fR
199.IX Subsection "Rxvt-unicode uses gobs of memory, how can I reduce that?"
200.PP
201Rxvt-unicode tries to obey the rule of not charging you for something you
202don't use. One thing you should try is to configure out all settings that
203you don't need, for example, Xft support is a resource hog by design,
204when used. Compiling it out ensures that no Xft font will be loaded
205accidentally when rxvt-unicode tries to find a font for your characters.
206.PP
207Also, many people (me included) like large windows and even larger
208scrollback buffers: Without \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR, rxvt-unicode will use
2096 bytes per screen cell. For a 160x?? window this amounts to almost a
210kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
211use 10 Megabytes of memory. With \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR it gets worse, as
212rxvt-unicode then uses 8 bytes per screen cell.
213.PP
214\fIHow can I start @@URXVT_NAME@@d in a race-free way?\fR
215.IX Subsection "How can I start @@URXVT_NAME@@d in a race-free way?"
216.PP
217Try \f(CW\*(C`@@URXVT_NAME@@d \-f \-o\*(C'\fR, which tells @@URXVT_NAME@@d to open the
218display, create the listening socket and then fork.
219.PP
220\fIHow can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c?\fR
221.IX Subsection "How can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c?"
222.PP
223If you want to start @@URXVT_NAME@@d automatically whenever you run
224@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
225.PP
226.Vb 6

230\& @@URXVT_NAME@@d -q -o -f
231\& @@URXVT_NAME@@c "$@"
232\& fi
233.Ve
234.PP
235This tries to create a new terminal, and if fails with exit status 2,
236meaning it couldn't connect to the daemon, it will start the daemon and
237re-run the command. Subsequent invocations of the script will re-use the
238existing daemon.
239.PP
240\fIHow do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.\fR
241.IX Subsection "How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc."
242.PP
243The original rxvt and rxvt-unicode always export the variable \*(L"\s-1COLORTERM\s0\*(R",
244so you can check and see if that is set. Note that several programs, \s-1JED\s0,
245slrn, Midnight Commander automatically check this variable to decide
246whether or not to use color.
247.PP
248\fIHow do I set the correct, full \s-1IP\s0 address for the \s-1DISPLAY\s0 variable?\fR
249.IX Subsection "How do I set the correct, full IP address for the DISPLAY variable?"
250.PP
251If you've compiled rxvt-unicode with \s-1DISPLAY_IS_IP\s0 and have enabled
252insecure mode then it is possible to use the following shell script
253snippets to correctly set the display. If your version of rxvt-unicode
254wasn't also compiled with \s-1ESCZ_ANSWER\s0 (as assumed in these snippets) then
255the \s-1COLORTERM\s0 variable can be used to distinguish rxvt-unicode from a
256regular xterm.

210.IX Subsection "During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?"
211These are caused by the \f(CW\*(C`readline\*(C'\fR perl extension. Under normal
212circumstances, it will move your cursor around when you click into the
213line that contains it. It tries hard not to do this at the wrong moment,
214but when running a program that doesn't parse cursor movements or in some
215cases during rlogin sessions, it fails to detect this properly.
216.PP
217You can permamently switch this feature off by disabling the \f(CW\*(C`readline\*(C'\fR

223.Sh "Why doesn't rxvt-unicode read my resources?"
224.IX Subsection "Why doesn't rxvt-unicode read my resources?"
225Well, why, indeed? It does, in a way very similar to other X
226applications. Most importantly, this means that if you or your \s-1OS\s0 loads
227resources into the X display (the right way to do it), rxvt-unicode will
228ignore any resource files in your home directory. It will only read
229\&\fI$HOME/.Xdefaults\fR when no resources are attached to the display.
230.PP
231If you have or use an \fI$HOME/.Xresources\fR file, chances are that
232resources are loaded into your X\-server. In this case, you have to
233re-login after every change (or run \fIxrdb \-merge \f(CI$HOME\fI/.Xresources\fR).
234.PP
235Also consider the form resources have to use:
236.PP

240.PP
241If you want to use another form (there are lots of different ways of
242specifying resources), make sure you understand wether and why it
243works. If unsure, use the form above.
244.Sh "I can't get transparency working, what am I doing wrong?"
245.IX Subsection "I can't get transparency working, what am I doing wrong?"
246First of all, transparency isn't officially supported in rxvt\-unicode, so
247you are mostly on your own. Do not bug the author about it (but you may
248bug everybody else). Also, if you can't get it working consider it a rite
249of passage: ... and you failed.

251Here are four ways to get transparency. \fBDo\fR read the manpage and option
252descriptions for the programs mentioned and rxvt\-unicode. Really, do it!

427.IX Subsection "Why does rxvt-unicode sometimes leave pixel droppings?"
428.PP
429Most fonts were not designed for terminal use, which means that character
430size varies a lot. A font that is otherwise fine for terminal use might
431contain some characters that are simply too wide. Rxvt-unicode will avoid
432these characters. For characters that are just \*(L"a bit\*(R" too wide a special
433\&\*(L"careful\*(R" rendering mode is used that redraws adjacent characters.
434.PP
435All of this requires that fonts do not lie about character sizes,
436however: Xft fonts often draw glyphs larger than their acclaimed bounding
437box, and rxvt-unicode has no way of detecting this (the correct way is to
438ask for the character bounding box, which unfortunately is wrong in these
439cases).
440.PP
441It's not clear (to me at least), wether this is a bug in Xft, freetype,
442or the respective font. If you encounter this problem you might try using
443the \f(CW\*(C`\-lsp\*(C'\fR option to give the font more height. If that doesn't work, you
444might be forced to use a different font.

465For some unexplainable reason, some rare programs assume a very weird

470In the meantime, you can either edit your \f(CW\*(C`rxvt\-unicode\*(C'\fR terminfo

604Most fonts do not contain the full range of Unicode, which is

607to display.
608.PP
609\&\fBrxvt-unicode\fR makes a best-effort try at finding a replacement
610font. Often the result is fine, but sometimes the chosen font looks
611bad/ugly/wrong. Some fonts have totally strange characters that don't
612resemble the correct glyph at all, and rxvt-unicode lacks the artificial
613intelligence to detect that a specific glyph is wrong: it has to believe
614the font that the characters it claims to contain indeed look correct.
615.PP
616In that case, select a font of your taste and add it to the font list,
617e.g.:

623When rxvt-unicode sees a character, it will first look at the base

625next font, and so on. Specifying your own fonts will also speed up this
626search and use less resources within rxvt-unicode and the X\-server.
627.PP
628The only limitation is that none of the fonts may be larger than the base
629font, as the base font defines the terminal character cell size, which
630must be the same due to the way terminals work.

632\fIWhy do some chinese characters look so different than others?\fR

635This is because there is a difference between script and language \*(--
636rxvt-unicode does not know which language the text that is output is,
637as it only knows the unicode character codes. If rxvt-unicode first
638sees a japanese/chinese character, it might choose a japanese font for
639display. Subsequent japanese characters will use that font. Now, many
640chinese characters aren't represented in japanese fonts, so when the first
641non-japanese character comes up, rxvt-unicode will look for a chinese font
642\&\*(-- unfortunately at this point, it will still use the japanese font for
643chinese characters that are also in the japanese font.
644.PP
645The workaround is easy: just tag a chinese font at the end of your font
646list (see the previous question). The key is to view the font list as
647a preference list: If you expect more japanese, list a japanese font
648first. If you expect more chinese, put a chinese font first.
649.PP
650In the future it might be possible to switch language preferences at

1071Well, why, indeed? It does, in a way very similar to other X

1074ignore any resource files in your home directory. It will only read

1077If you have or use an \fI$HOME/.Xresources\fR file, chances are that

625bad/ugly/wrong. Some fonts have totally strange characters that don't
626resemble the correct glyph at all, and rxvt-unicode lacks the artificial
627intelligence to detect that a specific glyph is wrong: it has to believe
628the font that the characters it claims to contain indeed look correct.
629.PP 1266.PP
630In that case, select a font of your taste and add it to the font list, 1267Unlike some other terminals, rxvt-unicode has no encoding switch, and no
631e.g.: 1268specific \*(L"utf\-8\*(R" mode, such as xterm. In fact, it doesn't even know about
1269\&\s-1UTF\-8\s0 or any other encodings with respect to terminal I/O.
1270.PP
1271The reasons is that there exists a perfectly fine mechanism for selecting
1272the encoding, doing I/O and (most important) communicating this to all
1273applications so everybody agrees on character properties such as width
1274and code number. This mechanism is the \fIlocale\fR. Applications not using
1275that info will have problems (for example, \f(CW\*(C`xterm\*(C'\fR gets the width of
1276characters wrong as it uses it's own, locale-independent table under all
1277locales).
1278.PP
1279Rxvt-unicode uses the \f(CW\*(C`LC_CTYPE\*(C'\fR locale category to select encoding. All
1280programs doing the same (that is, most) will automatically agree in the
1281interpretation of characters.
1282.PP
1283Unfortunately, there is no system-independent way to select locales, nor
1284is there a standard on how locale specifiers will look like.
1285.PP
1286On most systems, the content of the \f(CW\*(C`LC_CTYPE\*(C'\fR environment variable
1287contains an arbitrary string which corresponds to an already-installed
1288locale. Common names for locales are \f(CW\*(C`en_US.UTF\-8\*(C'\fR, \f(CW\*(C`de_DE.ISO\-8859\-15\*(C'\fR,
1289\&\f(CW\*(C`ja_JP.EUC\-JP\*(C'\fR, i.e. \f(CW\*(C`language_country.encoding\*(C'\fR, but other forms
1290(i.e. \f(CW\*(C`de\*(C'\fR or \f(CW\*(C`german\*(C'\fR) are also common.
1291.PP
1292Rxvt-unicode ignores all other locale categories, and except for
1293the encoding, ignores country or language-specific settings,
1294i.e. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR and \f(CW\*(C`ja_JP.UTF\-8\*(C'\fR are the normally same to

641.PP 1311.PP
642The only limitation is that none of the fonts may be larger than the base 1312Sometimes this capability is rather handy when you want to work in
643font, as the base font defines the terminal character cell size, which 1313one locale (e.g. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR) but some programs don't support it

647This is because there is a difference between script and language \*(--
648rxvt-unicode does not know which language the text that is output is,
649as it only knows the unicode character codes. If rxvt-unicode first
650sees a japanese/chinese character, it might choose a japanese font for
651display. Subsequent japanese characters will use that font. Now, many
652chinese characters aren't represented in japanese fonts, so when the first
653non-japanese character comes up, rxvt-unicode will look for a chinese font
654\&\*(-- unfortunately at this point, it will still use the japanese font for
655chinese characters that are also in the japanese font.
656.PP 1316.PP
657The workaround is easy: just tag a chinese font at the end of your font 1317.Vb 3

670Most fonts were not designed for terminal use, which means that character
671size varies a lot. A font that is otherwise fine for terminal use might
672contain some characters that are simply too wide. Rxvt-unicode will avoid
673these characters. For characters that are just \*(L"a bit\*(R" too wide a special
674\&\*(L"careful\*(R" rendering mode is used that redraws adjacent characters.
675.PP 1329.PP
676All of this requires that fonts do not lie about character sizes, 1330Try a search engine, as this is slightly different for every input method server.
677however: Xft fonts often draw glyphs larger than their acclaimed bounding
678box, and rxvt-unicode has no way of detecting this (the correct way is to
679ask for the character bounding box, which unfortunately is wrong in these
680cases).

682It's not clear (to me at least), wether this is a bug in Xft, freetype, 1332Here is a checklist:

788.Sh "Is there an option to switch encodings?"
789.IX Subsection "Is there an option to switch encodings?"
790Unlike some other terminals, rxvt-unicode has no encoding switch, and no
791specific \*(L"utf\-8\*(R" mode, such as xterm. In fact, it doesn't even know about
792\&\s-1UTF\-8\s0 or any other encodings with respect to terminal I/O.
793.PP
794The reasons is that there exists a perfectly fine mechanism for selecting
795the encoding, doing I/O and (most important) communicating this to all
796applications so everybody agrees on character properties such as width
797and code number. This mechanism is the \fIlocale\fR. Applications not using
798that info will have problems (for example, \f(CW\*(C`xterm\*(C'\fR gets the width of
799characters wrong as it uses it's own, locale-independent table under all
800locales).
801.PP
802Rxvt-unicode uses the \f(CW\*(C`LC_CTYPE\*(C'\fR locale category to select encoding. All
803programs doing the same (that is, most) will automatically agree in the
804interpretation of characters.
805.PP
806Unfortunately, there is no system-independent way to select locales, nor
807is there a standard on how locale specifiers will look like.
808.PP
809On most systems, the content of the \f(CW\*(C`LC_CTYPE\*(C'\fR environment variable
810contains an arbitrary string which corresponds to an already-installed
811locale. Common names for locales are \f(CW\*(C`en_US.UTF\-8\*(C'\fR, \f(CW\*(C`de_DE.ISO\-8859\-15\*(C'\fR,
812\&\f(CW\*(C`ja_JP.EUC\-JP\*(C'\fR, i.e. \f(CW\*(C`language_country.encoding\*(C'\fR, but other forms
813(i.e. \f(CW\*(C`de\*(C'\fR or \f(CW\*(C`german\*(C'\fR) are also common.
814.PP
815Rxvt-unicode ignores all other locale categories, and except for
816the encoding, ignores country or language-specific settings,
817i.e. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR and \f(CW\*(C`ja_JP.UTF\-8\*(C'\fR are the normally same to
818rxvt\-unicode.

820If you want to use a specific encoding you have to make sure you start
821rxvt-unicode with the correct \f(CW\*(C`LC_CTYPE\*(C'\fR category.
822.Sh "Can I switch locales at runtime?"

833Sometimes this capability is rather handy when you want to work in
834one locale (e.g. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR) but some programs don't support it
835(e.g. \s-1UTF\-8\s0). For example, I use this script to start \f(CW\*(C`xjdic\*(C'\fR, which
836first switches to a locale supported by xjdic and back later:

844You can also use xterm's \f(CW\*(C`luit\*(C'\fR program, which usually works fine, except

881Now you can start your terminal with \f(CW\*(C`LC_CTYPE=ja_JP.UTF\-8\*(C'\fR and still
882use your input method. Please note, however, that you will not be able to
883input characters outside \f(CW\*(C`EUC\-JP\*(C'\fR in a normal way then, as your input

886.IX Subsection "Rxvt-unicode crashes when the X Input Method changes or exits."
887Unfortunately, this is unavoidable, as the \s-1XIM\s0 protocol is racy by
888design. Applications can avoid some crashes at the expense of memory
889leaks, and Input Methods can avoid some crashes by careful ordering at
890exit time. \fBkinput2\fR (and derived input methods) generally succeeds,
891while \fB\s-1SCIM\s0\fR (or similar input methods) fails. In the end, however,
892crashes cannot be completely avoided even if both sides cooperate.

895.Sh "Rxvt-unicode uses gobs of memory, how can I reduce that?"

897Rxvt-unicode tries to obey the rule of not charging you for something you
898don't use. One thing you should try is to configure out all settings that
899you don't need, for example, Xft support is a resource hog by design,
900when used. Compiling it out ensures that no Xft font will be loaded
901accidentally when rxvt-unicode tries to find a font for your characters.

904scrollback buffers: Without \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR, rxvt-unicode will use
9056 bytes per screen cell. For a 160x?? window this amounts to almost a
906kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
907use 10 Megabytes of memory. With \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR it gets worse, as
908rxvt-unicode then uses 8 bytes per screen cell.
909.Sh "Can I speed up Xft rendering somehow?"
910.IX Subsection "Can I speed up Xft rendering somehow?"
911Yes, the most obvious way to speed it up is to avoid Xft entirely, as
912it is simply slow. If you still want Xft fonts you might try to disable
913antialiasing (by appending \f(CW\*(C`:antialias=false\*(C'\fR), which saves lots of
914memory and also speeds up rendering considerably.
915.Sh "Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?"
916.IX Subsection "Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?"
917Rxvt-unicode will use whatever you specify as a font. If it needs to
918fall back to it's default font search list it will prefer X11 core
919fonts, because they are small and fast, and then use Xft fonts. It has
920antialiasing disabled for most of them, because the author thinks they
921look best that way.
