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:

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.

221.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."
222.PP
223The original rxvt and rxvt-unicode always export the variable \*(L"\s-1COLORTERM\s0\*(R",
224so you can check and see if that is set. Note that several programs, \s-1JED\s0,
225slrn, Midnight Commander automatically check this variable to decide
226whether or not to use color.

229.IX Subsection "How do I set the correct, full IP address for the DISPLAY variable?"
230.PP
231If you've compiled rxvt-unicode with \s-1DISPLAY_IS_IP\s0 and have enabled
232insecure mode then it is possible to use the following shell script
233snippets to correctly set the display. If your version of rxvt-unicode
234wasn't also compiled with \s-1ESCZ_ANSWER\s0 (as assumed in these snippets) then
235the \s-1COLORTERM\s0 variable can be used to distinguish rxvt-unicode from a
236regular xterm.

415All of this requires that fonts do not lie about character sizes,

418ask for the character bounding box, which unfortunately is wrong in these

450In the meantime, you can either edit your \f(CW\*(C`rxvt\-unicode\*(C'\fR terminfo

584Most fonts do not contain the full range of Unicode, which is

586your system/os) have specified does not cover all the characters you want
587to display.
588.PP
589\&\fBrxvt-unicode\fR makes a best-effort try at finding a replacement
590font. Often the result is fine, but sometimes the chosen font looks
591bad/ugly/wrong. Some fonts have totally strange characters that don't
592resemble the correct glyph at all, and rxvt-unicode lacks the artificial
593intelligence to detect that a specific glyph is wrong: it has to believe
594the font that the characters it claims to contain indeed look correct.
595.PP
596In that case, select a font of your taste and add it to the font list,
597e.g.:

603When rxvt-unicode sees a character, it will first look at the base
604font. If the base font does not contain the character, it will go to the
605next font, and so on. Specifying your own fonts will also speed up this
606search and use less resources within rxvt-unicode and the X\-server.
607.PP
608The only limitation is that none of the fonts may be larger than the base
609font, as the base font defines the terminal character cell size, which
610must be the same due to the way terminals work.

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

615This is because there is a difference between script and language \*(--
616rxvt-unicode does not know which language the text that is output is,
617as it only knows the unicode character codes. If rxvt-unicode first
618sees a japanese/chinese character, it might choose a japanese font for
619display. Subsequent japanese characters will use that font. Now, many
620chinese characters aren't represented in japanese fonts, so when the first
621non-japanese character comes up, rxvt-unicode will look for a chinese font
622\&\*(-- unfortunately at this point, it will still use the japanese font for
623chinese characters that are also in the japanese font.
624.PP
625The workaround is easy: just tag a chinese font at the end of your font
626list (see the previous question). The key is to view the font list as
627a preference list: If you expect more japanese, list a japanese font
628first. If you expect more chinese, put a chinese font first.
629.PP
630In the future it might be possible to switch language preferences at
631runtime (the internal data structure has no problem with using different
632fonts for the same character at the same time, but no interface for this
633has been designed yet).

797if you use Backspace = \f(CW\*(C`^H\*(C'\fR, make sure that the termcap/terminfo value

800The Delete key is a another casualty of the ill-defined Backspace problem.
801To avoid confusion between the Backspace and Delete keys, the Delete
802key has been assigned an escape sequence to match the vt100 for Execute

867Well, why, indeed? It does, in a way very similar to other X
868applications. Most importantly, this means that if you or your \s-1OS\s0 loads
869resources into the X display (the right way to do it), rxvt-unicode will
870ignore any resource files in your home directory. It will only read
871\&\fI$HOME/.Xdefaults\fR when no resources are attached to the display.
872.PP
873If you have or use an \fI$HOME/.Xresources\fR file, chances are that

714.Sp
715Rxvt-unicode ignores all other locale categories, and except for
716the encoding, ignores country or language-specific settings,
717i.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
718rxvt\-unicode.
719.Sp
720If you want to use a specific encoding you have to make sure you start
721rxvt-unicode with the correct \f(CW\*(C`LC_CTYPE\*(C'\fR category.
722.IP "Can I switch locales at runtime?" 4
723.IX Item "Can I switch locales at runtime?"
724Yes, using an escape sequence. Try something like this, which sets
725rxvt\-unicode's idea of \f(CW\*(C`LC_CTYPE\*(C'\fR.
726.Sp

731See also the previous answer.
732.Sp
733Sometimes this capability is rather handy when you want to work in
734one locale (e.g. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR) but some programs don't support it
735(e.g. \s-1UTF\-8\s0). For example, I use this script to start \f(CW\*(C`xjdic\*(C'\fR, which
736first switches to a locale supported by xjdic and back later:
737.Sp
738.Vb 3
739\& printf '\ee]701;%s\e007' ja_JP.SJIS
740\& xjdic -js
741\& printf '\ee]701;%s\e007' de_DE.UTF-8
742.Ve
743.Sp
744You can also use xterm's \f(CW\*(C`luit\*(C'\fR program, which usually works fine, except
745for some locales where character width differs between program\- and
746rxvt\-unicode\-locales.
747.IP "Can I switch the fonts at runtime?" 4
748.IX Item "Can I switch the fonts at runtime?"
749Yes, using an escape sequence. Try something like this, which has the same

751.Sp
752.Vb 1
753\& printf '\ee]50;%s\e007' "9x15bold,xft:Kochi Gothic"
754.Ve
755.Sp
756This is useful if you e.g. work primarily with japanese (and prefer a
757japanese font), but you have to switch to chinese temporarily, where
758japanese fonts would only be in your way.

774You can specify separate locales for the input method and the rest of the

776.Sp
777.Vb 1

781Now you can start your terminal with \f(CW\*(C`LC_CTYPE=ja_JP.UTF\-8\*(C'\fR and still
782use your input method. Please note, however, that you will not be able to
783input characters outside \f(CW\*(C`EUC\-JP\*(C'\fR in a normal way then, as your input
784method limits you.
785.IP "Rxvt-unicode crashes when the X Input Method changes or exits." 4
786.IX Item "Rxvt-unicode crashes when the X Input Method changes or exits."
787Unfortunately, this is unavoidable, as the \s-1XIM\s0 protocol is racy by
788design. Applications can avoid some crashes at the expense of memory
789leaks, and Input Methods can avoid some crashes by careful ordering at
790exit time. \fBkinput2\fR (and derived input methods) generally succeeds,
791while \fB\s-1SCIM\s0\fR (or similar input methods) fails. In the end, however,
792crashes cannot be completely avoided even if both sides cooperate.

794So the only workaround is not to kill your Input Method Servers.
795.IP "Rxvt-unicode uses gobs of memory, how can I reduce that?" 4
796.IX Item "Rxvt-unicode uses gobs of memory, how can I reduce that?"
797Rxvt-unicode tries to obey the rule of not charging you for something you
798don't use. One thing you should try is to configure out all settings that
799you don't need, for example, Xft support is a resource hog by design,
800when used. Compiling it out ensures that no Xft font will be loaded
801accidentally when rxvt-unicode tries to find a font for your characters.
802.Sp
803Also, many people (me included) like large windows and even larger
804scrollback buffers: Without \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR, rxvt-unicode will use
8056 bytes per screen cell. For a 160x?? window this amounts to almost a
806kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
807use 10 Megabytes of memory. With \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR it gets worse, as
808rxvt-unicode then uses 8 bytes per screen cell.
809.IP "Can I speed up Xft rendering somehow?" 4
810.IX Item "Can I speed up Xft rendering somehow?"
811Yes, the most obvious way to speed it up is to avoid Xft entirely, as
812it is simply slow. If you still want Xft fonts you might try to disable
813antialiasing (by appending \f(CW\*(C`:antialias=false\*(C'\fR), which saves lots of
814memory and also speeds up rendering considerably.
815.IP "Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?" 4
816.IX Item "Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?"
817Rxvt-unicode will use whatever you specify as a font. If it needs to
818fall back to it's default font search list it will prefer X11 core
819fonts, because they are small and fast, and then use Xft fonts. It has
820antialiasing disabled for most of them, because the author thinks they
821look best that way.

906Assuming that the physical Backspace key corresponds to the
907BackSpace keysym (not likely for Linux ... see the following
908question) there are two standard values that can be used for
909Backspace: \f(CW\*(C`^H\*(C'\fR and \f(CW\*(C`^?\*(C'\fR.
910.Sp
911Historically, either value is correct, but rxvt-unicode adopts the debian
912policy of using \f(CW\*(C`^?\*(C'\fR when unsure, because it's the one only only correct
913choice :).
914.Sp
915Rxvt-unicode tries to inherit the current stty settings and uses the value
916of `erase' to guess the value for backspace. If rxvt-unicode wasn't
917started from a terminal (say, from a menu or by remote shell), then the
918system value of `erase', which corresponds to \s-1CERASE\s0 in <termios.h>, will
919be used (which may not be the same as your stty setting).
920.Sp
921For starting a new rxvt\-unicode:
922.Sp

951This helps satisfy some of the Backspace discrepancies that occur, but
952if you use Backspace = \f(CW\*(C`^H\*(C'\fR, make sure that the termcap/terminfo value
953properly reflects that.
954.Sp
955The Delete key is a another casualty of the ill-defined Backspace problem.
956To avoid confusion between the Backspace and Delete keys, the Delete
957key has been assigned an escape sequence to match the vt100 for Execute
958(\f(CW\*(C`ESC [ 3 ~\*(C'\fR) and is in the supplied termcap/terminfo.
