Also the escape +sequence C sets the window title to the version number. When +using the @@URXVT_NAME@@c client, the version displayed is that of the +daemon. + +=head3 Rxvt-unicode uses gobs of memory, how can I reduce that? + +Rxvt-unicode tries to obey the rule of not charging you for something you +don't use. One thing you should try is to configure out all settings that +you don't need, for example, Xft support is a resource hog by design, +when used. Compiling it out ensures that no Xft font will be loaded +accidentally when rxvt-unicode tries to find a font for your characters. + +Also, many people (me included) like large windows and even larger +scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use +6 bytes per screen cell. For a 160x?? window this amounts to almost a +kilobyte per line. A scrollback buffer of 10000 lines will then (if full) +use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as +rxvt-unicode then uses 8 bytes per screen cell. + +=head3 How can I start @@URXVT_NAME@@d in a race-free way? + +Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the +display, create the listening socket and then fork. + +=head3 How can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c? + +If you want to start @@URXVT_NAME@@d automatically whenever you run +@@URXVT_NAME@@c and the daemon isn't running yet, use this script: + + #!/bin/sh + @@URXVT_NAME@@c "$@" + if [ $? -eq 2 ]; then + @@URXVT_NAME@@d -q -o -f + @@URXVT_NAME@@c "$@" + fi + +This tries to create a new terminal, and if fails with exit status 2, +meaning it couldn't connect to the daemon, it will start the daemon and +re-run the command.

I need this to decide about setting colors etc. + +The original rxvt and rxvt-unicode always export the variable "COLORTERM", +so you can check and see if that is set. Note that several programs, JED, +slrn, Midnight Commander automatically check this variable to decide +whether or not to use color. + +=head3 How do I set the correct, full IP address for the DISPLAY variable? + +If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled +insecure mode then it is possible to use the following shell script +snippets to correctly set the display. If your version of rxvt-unicode +wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then +the COLORTERM variable can be used to distinguish rxvt-unicode from a +regular xterm. + +Courtesy of Chuck Blake with the following shell script +snippets: + + # Bourne/Korn/POSIX family of shells: + [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know + if [ ${TERM:-foo} = xterm ]; then + stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not + echo -n '^[Z' + read term_id + stty icanon echo + if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then + echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string + read DISPLAY # set it in our local shell + fi + fi + +=head3 How do I compile the manual pages on my own? + +You need to have a recent version of perl installed as F, +one that comes with F, F and F. Then go to +the doc subdirectory and enter C. + +=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat? + +I often get asked about this, and I think, no, they didn't cause extra +bloat. If you compare a minimal rxvt and a minimal urxvt, you can see +that the urxvt binary is larger (due to some encoding tables always being +compiled in), but it actually uses less memory (RSS) after startup. Even +with C<--disable-everything>, this comparison is a bit unfair, as many +features unique to urxvt (locale, encoding conversion, iso14755 etc.) are +already in use in this mode. + + text data bss drs rss filename + 98398 1664 24 15695 1824 rxvt --disable-everything + 188985 9048 66616 18222 1788 urxvt --disable-everything + +When you C<--enable-everything> (which I unfair, as this involves xft +and full locale/XIM support which are quite bloaty inside libX11 and my +libc), the two diverge, but not unreasonably so. + + text data bss drs rss filename + 163431 2152 24 20123 2060 rxvt --enable-everything + 1035683 49680 66648 29096 3680 urxvt --enable-everything + +The very large size of the text section is explained by the east-asian +encoding tables, which, if unused, take up disk space but nothing else +and can be compiled out unless you rely on X11 core fonts that use those +encodings. The BSS size comes from the 64k emergency buffer that my c++ +compiler allocates (but of course doesn't use unless you are out of +memory). Also, using an xft font instead of a core font immediately adds a +few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when +not used. + +Of course, due to every character using two or four bytes instead of one, +a large scrollback buffer will ultimately make rxvt-unicode use more +memory. + +Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this +still fares rather well. And compared to some monsters like gnome-terminal +(21152k + extra 4204k in separate processes) or konsole (22200k + extra +43180k in daemons that stay around after exit, plus half a minute of +startup time, including the hundreds of warnings it spits out), it fares +extremely well *g*. + +=head3 Why C++, isn't that unportable/bloated/uncool? + +Is this a question? :) It comes up very often. The simple answer is: I had +to write it, and C++ allowed me to write and maintain it in a fraction +of the time and effort (which is a scarce resource for me). Put even +shorter: It simply wouldn't exist without C++. + +My personal stance on this is that C++ is less portable than C, but in +the case of rxvt-unicode this hardly matters, as its portability limits +are defined by things like X11, pseudo terminals, locale support and unix +domain sockets, which are all less portable than C++ itself. + +Regarding the bloat, see the above question: It's easy to write programs +in C that use gobs of memory, an certainly possible to write programs in +C++ that don't. C++ also often comes with large libraries, but this is +not necessarily the case with GCC. Here is what rxvt links against on my +system with a minimal config: + + libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) + libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000) + libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000) + /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) + +And here is rxvt-unicode: + + libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000) + libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000) + libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000) + libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000) + /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000) + +No large bloated libraries (of course, none were linked in statically), +except maybe libX11 :) + + +=head2 Rendering, Font & Look and Feel Issues + +=head3 I can't get transparency working, what am I doing wrong? + +First of all, transparency isn't officially supported in rxvt-unicode, so +you are mostly on your own. Do not bug the author about it (but you may +bug everybody else). Also, if you can't get it working consider it a rite +of passage: ... and you failed. + +Here are four ways to get transparency. B read the manpage and option +descriptions for the programs mentioned and rxvt-unicode. Really, do it! + +1. Use inheritPixmap: + + Esetroot wallpaper.jpg + @@URXVT_NAME@@ -ip -tint red -sh 40 + +That works. If you think it doesn't, you lack transparency and tinting +support, or you are unable to read. + +2. Use a simple pixmap and emulate pseudo-transparency. This enables you +to use effects other than tinting and shading: Just shade/tint/whatever +your picture with gimp or any other tool: + + convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm + @@URXVT_NAME@@ -pixmap background.xpm -pe automove-background + +That works. If you think it doesn't, you lack XPM and Perl support, or you +are unable to read. + +3. Use an ARGB visual: + + @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc + +This requires XFT support, and the support of your X-server. If that +doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't +there yet, no matter what they claim. Rxvt-Unicode contains the necessary +bugfixes and workarounds for Xft and Xlib to make it work, but that +doesn't mean that your WM has the required kludges in place. + +4. Use xcompmgr and let it do the job: + + xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ + -set _NET_WM_WINDOW_OPACITY 0xc0000000 + +Then click on a window you want to make transparent. Replace C<0xc0000000> +by other values to change the degree of opacity. If it doesn't work and +your server crashes, you got to keep the pieces. + +=head3 Why does rxvt-unicode sometimes leave pixel droppings? + +Most fonts were not designed for terminal use, which means that character +size varies a lot. A font that is otherwise fine for terminal use might +contain some characters that are simply too wide. Rxvt-unicode will avoid +these characters. For characters that are just "a bit" too wide a special +"careful" rendering mode is used that redraws adjacent characters. + +All of this requires that fonts do not lie about character sizes, +however: Xft fonts often draw glyphs larger than their acclaimed bounding +box, and rxvt-unicode has no way of detecting this (the correct way is to +ask for the character bounding box, which unfortunately is wrong in these +cases). + +It's not clear (to me at least), whether this is a bug in Xft, freetype, +or the respective font. If you encounter this problem you might try using +the C<-lsp> option to give the font more height. If that doesn't work, you +might be forced to use a different font. + +All of this is not a problem when using X11 core fonts, as their bounding +box data is correct. + +=head3 How can I keep rxvt-unicode from using reverse video so much? + +First of all, make sure you are running with the right terminal settings +(C), which will get rid of most of these effects. Then +make sure you have specified colours for italic and bold, as otherwise +rxvt-unicode might use reverse video to simulate the effect: + + URxvt.colorBD: white + URxvt.colorIT: green + +=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that? + +For some unexplainable reason, some rare programs assume a very weird +colour palette when confronted with a terminal with more than the standard +8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix +these programs not to assume non-ISO colours without very good reasons. + +In the meantime, you can either edit your C terminfo +definition to only claim 8 colour support or use C, which will +fix colours but keep you from using other rxvt-unicode features. + +=head3 Can I switch the fonts at runtime? + +Yes, using an escape sequence. Try something like this, which has the same +effect as using the C<-fn> switch, and takes effect immediately: + + printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic" + +This is useful if you e.g. work primarily with japanese (and prefer a +japanese font), but you have to switch to chinese temporarily, where +japanese fonts would only be in your way. + +You can think of this as a kind of manual ISO-2022 switching. + +=head3 Why do italic characters look as if clipped? + +Many fonts have difficulties with italic characters and hinting. For +example, the otherwise very nicely hinted font C completely fails in its italic face. A workaround might be to +enable freetype autohinting, i.e. like this: + + URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true + URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true + +=head3 Can I speed up Xft rendering somehow? + +Yes, the most obvious way to speed it up is to avoid Xft entirely, as +it is simply slow. If you still want Xft fonts you might try to disable +antialiasing (by appending C<:antialias=false>), which saves lots of +memory and also speeds up rendering considerably. + +=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong? + +Rxvt-unicode will use whatever you specify as a font. If it needs to +fall back to its default font search list it will prefer X11 core +fonts, because they are small and fast, and then use Xft fonts. It has +antialiasing disabled for most of them, because the author thinks they +look best that way. + +If you want antialiasing, you have to specify the fonts manually. + +=head3 What's with this bold/blink stuff? + +If no bold colour is set via C, bold will invert text using the +standard foreground colour. + +For the standard background colour, blinking will actually make the +text blink when compiled with C<--enable-blinking>. with standard +colours. Without C<--enable-blinking>, the blink attribute will be +ignored. + +On ANSI colours, bold/blink attributes are used to set high-intensity +foreground/background colors. + +color0-7 are the low-intensity colors. + +color8-15 are the corresponding high-intensity colors. + +=head3 I don't like the screen colors. How do I change them? + +You can change the screen colors at run-time using F<~/.Xdefaults> +resources (or as long-options). + +Here are values that are supposed to resemble a VGA screen, +including the murky brown that passes for low-intensity yellow: + + URxvt.color0: #000000 + URxvt.color1: #A80000 + URxvt.color2: #00A800 + URxvt.color3: #A8A800 + URxvt.color4: #0000A8 + URxvt.color5: #A800A8 + URxvt.color6: #00A8A8 + URxvt.color7: #A8A8A8 + + URxvt.color8: #000054 + URxvt.color9: #FF0054 + URxvt.color10: #00FF54 + URxvt.color11: #FFFF54 + URxvt.color12: #0000FF + URxvt.color13: #FF00FF + URxvt.color14: #00FFFF + URxvt.color15: #FFFFFF + +And here is a more complete set of non-standard colors. + + URxvt.cursorColor: #dc74d1 + URxvt.pointerColor: #dc74d1 + URxvt.background: #0e0e0e + URxvt.foreground: #4ad5e1 + URxvt.color0: #000000 + URxvt.color8: #8b8f93 + URxvt.color1: #dc74d1 + URxvt.color9: #dc74d1 + URxvt.color2: #0eb8c7 + URxvt.color10: #0eb8c7 + URxvt.color3: #dfe37e + URxvt.color11: #dfe37e + URxvt.color5: #9e88f0 + URxvt.color13: #9e88f0 + URxvt.color6: #73f7ff + URxvt.color14: #73f7ff + URxvt.color7: #e1dddd + URxvt.color15: #e1dddd + +They have been described (not by me) as "pretty girly". + +=head3 Why do some characters look so much different than others? + +See next entry. + +=head3 How does rxvt-unicode choose fonts? + +Most fonts do not contain the full range of Unicode, which is +fine. Chances are that the font you (or the admin/package maintainer of +your system/os) have specified does not cover all the characters you want +to display. + +B makes a best-effort try at finding a replacement +font. Often the result is fine, but sometimes the chosen font looks +bad/ugly/wrong. Some fonts have totally strange characters that don't +resemble the correct glyph at all, and rxvt-unicode lacks the artificial +intelligence to detect that a specific glyph is wrong: it has to believe +the font that the characters it claims to contain indeed look correct. + +In that case, select a font of your taste and add it to the font list, +e.g.: + + @@URXVT_NAME@@ -fn basefont,font2,font3... + +When rxvt-unicode sees a character, it will first look at the base +font. If the base font does not contain the character, it will go to the +next font, and so on. Specifying your own fonts will also speed up this +search and use less resources within rxvt-unicode and the X-server. + +The only limitation is that none of the fonts may be larger than the base +font, as the base font defines the terminal character cell size, which +must be the same due to the way terminals work. + +=head3 Why do some chinese characters look so different than others? + +This is because there is a difference between script and language -- +rxvt-unicode does not know which language the text that is output is, +as it only knows the unicode character codes. If rxvt-unicode first +sees a japanese/chinese character, it might choose a japanese font for +display. Subsequent japanese characters will use that font. Now, many +chinese characters aren't represented in japanese fonts, so when the first +non-japanese character comes up, rxvt-unicode will look for a chinese font +-- unfortunately at this point, it will still use the japanese font for +chinese characters that are also in the japanese font. + +The workaround is easy: just tag a chinese font at the end of your font +list (see the previous question). The key is to view the font list as +a preference list: If you expect more japanese, list a japanese font +first. If you expect more chinese, put a chinese font first. + +In the future it might be possible to switch language preferences at +runtime (the internal data structure has no problem with using different +fonts for the same character at the same time, but no interface for this +has been designed yet). + +Until then, you might get away with switching fonts at runtime (see L later in this document). + +=head2 Keyboard, Mouse & User Interaction + +=head3 The new selection selects pieces that are too big, how can I select single words? + +If you want to select e.g. alphanumeric words, you can use the following +setting: + + URxvt.selection.pattern-0: ([[:word:]]+) + +If you click more than twice, the selection will be extended +more and more. + +To get a selection that is very similar to the old code, try this pattern: + + URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) + +Please also note that the I combination also +selects words like the old code. + +=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it? + +You can disable the perl extension completely by setting the +B resource to the empty string, which also keeps +rxvt-unicode from initialising perl, saving memory. + +If you only want to disable specific features, you first have to +identify which perl extension is responsible. For this, read the section +B in the @@URXVT_NAME@@perl(3) manpage. For +example, to disable the B and B, specify +this B resource: + + URxvt.perl-ext-common: default,-selection-popup,-option-popup + +This will keep the default extensions, but disable the two popup +extensions. Some extensions can also be configured, for example, +scrollback search mode is triggered by B. You can move it to any +other combination either by setting the B resource: + + URxvt.searchable-scrollback: CM-s + +=head3 The cursor moves when selecting text in the current input line, how do I switch this off? + +See next entry. + +=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this? + +These are caused by the C perl extension. Under normal +circumstances, it will move your cursor around when you click into the +line that contains it. It tries hard not to do this at the wrong moment, +but when running a program that doesn't parse cursor movements or in some +cases during rlogin sessions, it fails to detect this properly. + +You can permanently switch this feature off by disabling the C +extension: + + URxvt.perl-ext-common: default,-readline + +=head3 My numerical keypad acts weird and generates differing output? + +Some Debian GNUL/Linux users seem to have this problem, although no +specific details were reported so far. It is possible that this is caused +by the wrong C setting, although the details of whether and how +this can happen are unknown, as C should offer a compatible +keymap. See the answer to the previous question, and please report if that +helped. + +=head3 My Compose (Multi_key) key is no longer working. + +The most common causes for this are that either your locale is not set +correctly, or you specified a B that is not supported by +your input method. For example, if you specified B and +your input method (e.g. the default input method handling Compose keys) +does not support this (for instance because it is not visual), then +rxvt-unicode will continue without an input method. + +In this case either do not specify a B or specify more than +one pre-edit style, such as B. + +=head3 I cannot type C to get an ASCII NUL character due to ISO 14755 + +Either try C alone (it often is mapped to ASCII NUL even on +international keyboards) or simply use ISO 14755 support to your +advantage, typing to get a ASCII NUL. This works for other +codes, too, such as C to type the default telnet escape +character and so on. + +=head3 Mouse cut/paste suddenly no longer works. + +Make sure that mouse reporting is actually turned off since killing +some editors prematurely may leave the mouse in mouse report mode. I've +heard that tcsh may use mouse reporting unless it otherwise specified. A +quick check is to see if cut/paste works when the Alt or Shift keys are +depressed. + +=head3 What's with the strange Backspace/Delete key behaviour? + +Assuming that the physical Backspace key corresponds to the +Backspace keysym (not likely for Linux ... see the following +question) there are two standard values that can be used for +Backspace: C<^H> and C<^?>. + +Historically, either value is correct, but rxvt-unicode adopts the debian +policy of using C<^?> when unsure, because it's the one only only correct +choice :). + +Rxvt-unicode tries to inherit the current stty settings and uses the value +of `erase' to guess the value for backspace. If rxvt-unicode wasn't +started from a terminal (say, from a menu or by remote shell), then the +system value of `erase', which corresponds to CERASE in , will +be used (which may not be the same as your stty setting). + +For starting a new rxvt-unicode: + + # use Backspace = ^H + $ stty erase ^H + $ @@URXVT_NAME@@ + + # use Backspace = ^? + $ stty erase ^? + $ @@URXVT_NAME@@ + +Toggle with C / C. + +For an existing rxvt-unicode: + + # use Backspace = ^H + $ stty erase ^H + $ echo -n "^[[36h" + + # use Backspace = ^? + $ stty erase ^? + $ echo -n "^[[36l" + +This helps satisfy some of the Backspace discrepancies that occur, but +if you use Backspace = C<^H>, make sure that the termcap/terminfo value +properly reflects that. + +The Delete key is a another casualty of the ill-defined Backspace problem. +To avoid confusion between the Backspace and Delete keys, the Delete +key has been assigned an escape sequence to match the vt100 for Execute +(C) and is in the supplied termcap/terminfo. + +Some other Backspace problems: + +some editors use termcap/terminfo, +some editors (vim I'm told) expect Backspace = ^H, +GNU Emacs (and Emacs-like editors) use ^H for help. + +Perhaps someday this will all be resolved in a consistent manner. + +=head3 I don't like the key-bindings. How do I change them? + +There are some compile-time selections available via configure. Unless +you have run "configure" with the C<--disable-resources> option you can +use the `keysym' resource to alter the keystrings associated with keysyms. + +Here's an example for a URxvt session started using C<@@URXVT_NAME@@ -name URxvt> + + URxvt.keysym.Home: \033[1~ + URxvt.keysym.End: \033[4~ + URxvt.keysym.C-apostrophe: \033 + URxvt.keysym.C-slash: \033 + URxvt.keysym.C-semicolon: \033 + URxvt.keysym.C-grave: \033 + URxvt.keysym.C-comma: \033 + URxvt.keysym.C-period: \033 + URxvt.keysym.C-0x60: \033 + URxvt.keysym.C-Tab: \033 + URxvt.keysym.C-Return: \033 + URxvt.keysym.S-Return: \033 + URxvt.keysym.S-space: \033 + URxvt.keysym.M-Up: \033 + URxvt.keysym.M-Down: \033 + URxvt.keysym.M-Left: \033 + URxvt.keysym.M-Right: \033 + URxvt.keysym.M-C-0: list \033 + URxvt.keysym.M-C-a: list \033 + URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007 + +See some more examples in the documentation for the B resource. + +=head3 I'm using keyboard model XXX that has extra Prior/Next/Insert keys.

So don't be +overwhelmed. A special note: the C<9x15bold> mentioned above is actually +the version from XFree-3.3, as XFree-4 replaced it by a totally different +font (different glyphs for C<;> and many other harmless characters), +while the second font is actually the C<9x15bold> from XFree4/XOrg. The +bold version has less chars than the medium version, so I use it for rare +characters, too. When editing sources with vim, I use italic for comments +and other stuff, which looks quite good with Bitstream Vera anti-aliased. + +Terminus is a quite bad font (many very wrong glyphs), but for most of my +purposes, it works, and gives a different look, as my normal (Non-bold) +font is already bold, and I want to see a difference between bold and +normal fonts. + +Please note that I used the C instance name and not the C +class name. Thats because I use different configs for different purposes, +for example, my IRC window is started with C<-name IRC>, and uses these +defaults: + + IRC*title: IRC + IRC*geometry: 87x12+535+542 + IRC*saveLines: 0 + IRC*mapAlert: true + IRC*font: suxuseuro + IRC*boldFont: suxuseuro + IRC*colorBD: white + IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007 + IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007 + +C and C switch between two different font +sizes. C allows me to keep an eye (and actually read) +stuff while keeping a very small window. If somebody pastes something +complicated (e.g. japanese), I temporarily switch to a larger font. + +The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor +C). I also have some resources in a separate C<.Xdefaults-hostname> +file for different hosts, for example, on ym main desktop, I use: + + URxvt.keysym.C-M-q: command:\033[3;5;5t + URxvt.keysym.C-M-y: command:\033[3;5;606t + URxvt.keysym.C-M-e: command:\033[3;1605;5t + URxvt.keysym.C-M-c: command:\033[3;1605;606t + URxvt.keysym.C-M-p: perl:test + +The first for keysym definitions allow me to quickly bring some windows +in the layout I like most. Ion users might start laughing but will stop +immediately when I tell them that I use my own Fvwm2 module for much the +same effect as Ion provides, and I only very rarely use the above key +combinations :-> + +=head3 Why doesn't rxvt-unicode read my resources? + +Well, why, indeed? It does, in a way very similar to other X +applications. Most importantly, this means that if you or your OS loads +resources into the X display (the right way to do it), rxvt-unicode will +ignore any resource files in your home directory. It will only read +F<$HOME/.Xdefaults> when no resources are attached to the display. + +If you have or use an F<$HOME/.Xresources> file, chances are that +resources are loaded into your X-server. In this case, you have to +re-login after every change (or run F). + +Also consider the form resources have to use: + + URxvt.resource: value + +If you want to use another form (there are lots of different ways of +specifying resources), make sure you understand whether and why it +works. If unsure, use the form above. + +=head3 When I log-in to another system it tells me about missing terminfo data? + +The terminal description used by rxvt-unicode is not as widely available +as that for xterm, or even rxvt (for which the same problem often arises). + +The correct solution for this problem is to install the terminfo, this can +be done like this (with ncurses' infocmp): + + REMOTE=remotesystem.domain + infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti" + +... or by installing rxvt-unicode normally on the remote system, + +If you cannot or do not want to do this, then you can simply set +C or even C, and live with the small number of +problems arising, which includes wrong keymapping, less and different +colours and some refresh errors in fullscreen applications. It's a nice +quick-and-dirty workaround for rare cases, though. + +If you always want to do this (and are fine with the consequences) you +can either recompile rxvt-unicode with the desired TERM value or use a +resource to set it: + + URxvt.termName: rxvt + +If you don't plan to use B (quite common...) you could also replace +the rxvt terminfo file with the rxvt-unicode one and use C. + +=head3 C outputs some error when compiling the terminfo entry. + +Most likely it's the empty definition for C. Just replace it by +C and try again. + +=head3 C's readline does not work correctly under @@URXVT_NAME@@. + +See next entry. + +=head3 I need a termcap file entry. + +One reason you might want this is that some distributions or operating +systems still compile some programs using the long-obsoleted termcap +library (Fedora Core's bash is one example) and rely on a termcap entry +for C. + +You could use rxvt's termcap entry with reasonable results in many cases. +You can also create a termcap entry by using terminfo's infocmp program +like this: + + infocmp -C rxvt-unicode + +Or you could use this termcap entry, generated by the command above: + + rxvt-unicode|rxvt-unicode terminal (X Window System):\ + :am:bw:eo:km:mi:ms:xn:xo:\ + :co#80:it#8:li#24:lm#0:\ + :AL=\E[%dL:DC=\E[%dP:DL=\E[%dM:DO=\E[%dB:IC=\E[%d@:\ + :K1=\EOw:K2=\EOu:K3=\EOy:K4=\EOq:K5=\EOs:LE=\E[%dD:\ + :RI=\E[%dC:SF=\E[%dS:SR=\E[%dT:UP=\E[%dA:ae=\E(B:al=\E[L:\ + :as=\E(0:bl=^G:cd=\E[J:ce=\E[K:cl=\E[H\E[2J:\ + :cm=\E[%i%d;%dH:cr=^M:cs=\E[%i%d;%dr:ct=\E[3g:dc=\E[P:\ + :dl=\E[M:do=^J:ec=\E[%dX:ei=\E[4l:ho=\E[H:\ + :i1=\E[?47l\E=\E[?1l:ic=\E[@:im=\E[4h:\ + :is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;3;4;6l\E[4l:\ + :k1=\E[11~:k2=\E[12~:k3=\E[13~:k4=\E[14~:k5=\E[15~:\ + :k6=\E[17~:k7=\E[18~:k8=\E[19~:k9=\E[20~:kD=\E[3~:\ + :kI=\E[2~:kN=\E[6~:kP=\E[5~:kb=\177:kd=\EOB:ke=\E[?1l\E>:\ + :kh=\E[7~:kl=\EOD:kr=\EOC:ks=\E[?1h\E=:ku=\EOA:le=^H:\ + :mb=\E[5m:md=\E[1m:me=\E[m\017:mr=\E[7m:nd=\E[C:rc=\E8:\ + :sc=\E7:se=\E[27m:sf=^J:so=\E[7m:sr=\EM:st=\EH:ta=^I:\ + :te=\E[r\E[?1049l:ti=\E[?1049h:ue=\E[24m:up=\E[A:\ + :us=\E[4m:vb=\E[?5h\E[?5l:ve=\E[?25h:vi=\E[?25l:\ + :vs=\E[?25h: + +=head3 Why does C no longer have coloured output? + +The C in the GNU coreutils unfortunately doesn't use terminfo to +decide whether a terminal has colour, but uses its own configuration +file. Needless to say, C is not in its default file (among +with most other terminals supporting colour). Either add: + + TERM rxvt-unicode + +to C or simply add: + + alias ls='ls --color=auto' + +to your C<.profile> or C<.bashrc>. + +=head3 Why doesn't vim/emacs etc. use the 88 colour mode? + +See next entry. + +=head3 Why doesn't vim/emacs etc. make use of italic? + +See next entry. + +=head3 Why are the secondary screen-related options not working properly? + +Make sure you are using C. Some pre-packaged +distributions (most notably Debian GNU/Linux) break rxvt-unicode +by setting C to C, which doesn't have these extra +features. Unfortunately, some of these (most notably, again, Debian +GNU/Linux) furthermore fail to even install the C terminfo +file, so you will need to install it on your own (See the question B on +how to do this). + + +=head2 Encoding / Locale / Input Method Issues + +=head3 Rxvt-unicode does not seem to understand the selected encoding? + +See next entry. + +=head3 Unicode does not seem to work? + +If you encounter strange problems like typing an accented character but +getting two unrelated other characters or similar, or if program output is +subtly garbled, then you should check your locale settings. + +Rxvt-unicode must be started with the same C setting as the +programs. Often rxvt-unicode is started in the C locale, while the +login script running within the rxvt-unicode window changes the locale to +something else, e.g. C. Needless to say, this is not going to work. + +The best thing is to fix your startup environment, as you will likely run +into other problems. If nothing works you can try this in your .profile. + + printf '\33]701;%s\007' "$LC_CTYPE" + +If this doesn't work, then maybe you use a C specification not +supported on your systems. Some systems have a C command which +displays this (also, C can be used to check locale settings, as +it will complain loudly if it cannot set the locale). If it displays something +like: + + locale: Cannot set LC_CTYPE to default locale: ... + +Then the locale you specified is not supported on your system. + +If nothing works and you are sure that everything is set correctly then +you will need to remember a little known fact: Some programs just don't +support locales :( + +=head3 How does rxvt-unicode determine the encoding to use? + +See next entry. + +=head3 Is there an option to switch encodings? + +Unlike some other terminals, rxvt-unicode has no encoding switch, and no +specific "utf-8" mode, such as xterm. In fact, it doesn't even know about +UTF-8 or any other encodings with respect to terminal I/O. + +The reasons is that there exists a perfectly fine mechanism for selecting +the encoding, doing I/O and (most important) communicating this to all +applications so everybody agrees on character properties such as width +and code number. This mechanism is the I. Applications not using +that info will have problems (for example, C gets the width of +characters wrong as it uses its own, locale-independent table under all +locales). + +Rxvt-unicode uses the C locale category to select encoding. All +programs doing the same (that is, most) will automatically agree in the +interpretation of characters. + +Unfortunately, there is no system-independent way to select locales, nor +is there a standard on how locale specifiers will look like. + +On most systems, the content of the C environment variable +contains an arbitrary string which corresponds to an already-installed +locale. Common names for locales are C, C, +C, i.e. C, but other forms +(i.e. C or C) are also common. + +Rxvt-unicode ignores all other locale categories, and except for +the encoding, ignores country or language-specific settings, +i.e. C and C are the normally same to +rxvt-unicode. + +If you want to use a specific encoding you have to make sure you start +rxvt-unicode with the correct C category. + +=head3 Can I switch locales at runtime? + +Yes, using an escape sequence. Try something like this, which sets +rxvt-unicode's idea of C. + + printf '\33]701;%s\007' ja_JP.SJIS + +See also the previous answer. + +Sometimes this capability is rather handy when you want to work in +one locale (e.g. C) but some programs don't support it +(e.g. UTF-8). For example, I use this script to start C, which +first switches to a locale supported by xjdic and back later: + + printf '\33]701;%s\007' ja_JP.SJIS + xjdic -js + printf '\33]701;%s\007' de_DE.UTF-8 + +You can also use xterm's C program, which usually works fine, except +for some locales where character width differs between program- and +rxvt-unicode-locales. + +=head3 I have problems getting my input method working. + +Try a search engine, as this is slightly different for every input method server. + +Here is a checklist: + +=over 4 + +=item - Make sure your locale I the imLocale are supported on your OS. + +Try C or check the documentation for your OS. + +=item - Make sure your locale or imLocale matches a locale supported by your XIM. + +For example, B does not support UTF-8 locales, you should use +C or equivalent. + +=item - Make sure your XIM server is actually running. + +=item - Make sure the C environment variable is set correctly when I rxvt-unicode. + +When you want to use e.g. B, it must be set to +C<@im=kinput2>. For B, use C<@im=SCIM>. You can see what input +method servers are running with this command: + + xprop -root XIM_SERVERS + +=item + +=back + +=head3 My input method wants but I want UTF-8, what can I do? + +You can specify separate locales for the input method and the rest of the +terminal, using the resource C: + + URxvt.imlocale: ja_JP.EUC-JP + +Now you can start your terminal with C and still +use your input method. Please note, however, that, depending on your Xlib +version, you may not be able to input characters outside C in a +normal way then, as your input method limits you. + +=head3 Rxvt-unicode crashes when the X Input Method changes or exits. + +Unfortunately, this is unavoidable, as the XIM protocol is racy by +design. Applications can avoid some crashes at the expense of memory +leaks, and Input Methods can avoid some crashes by careful ordering at +exit time. B (and derived input methods) generally succeeds, +while B (or similar input methods) fails. In the end, however, +crashes cannot be completely avoided even if both sides cooperate. + +So the only workaround is not to kill your Input Method Servers. + + +=head2 Operating Systems / Package Maintaining + +=head3 I am using Debian GNU/Linux and have a problem... + +The Debian GNU/Linux package of rxvt-unicode in sarge contains large +patches that considerably change the behaviour of rxvt-unicode (but +unfortunately this notice has been removed). Before reporting a bug to +the original rxvt-unicode author please download and install the genuine +version (L) and try to reproduce +the problem. If you cannot, chances are that the problems are specific to +Debian GNU/Linux, in which case it should be reported via the Debian Bug +Tracking System (use C to report the bug). + +For other problems that also affect the Debian package, you can and +probably should use the Debian BTS, too, because, after all, it's also a +bug in the Debian version and it serves as a reminder for other users that +might encounter the same issue. + +=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation? + +You should build one binary with the default options. F +now enables most useful options, and the trend goes to making them +runtime-switchable, too, so there is usually no drawback to enabling them, +except higher disk and possibly memory usage. The perl interpreter should +be enabled, as important functionality (menus, selection, likely more in +the future) depends on it. + +You should not overwrite the C snd C resources +system-wide (except maybe with C). This will result in useful +behaviour. If your distribution aims at low memory, add an empty +C resource to the app-defaults file. This will keep the +perl interpreter disabled until the user enables it. + +If you can/want build more binaries, I recommend building a minimal +one with C<--disable-everything> (very useful) and a maximal one with +C<--enable-everything> (less useful, it will be very big due to a lot of +encodings built-in that increase download times and are rarely used). + +=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? + +It should be, starting with release 7.1. You are encouraged to properly +install urxvt with privileges necessary for your OS now. + +When rxvt-unicode detects that it runs setuid or setgid, it will fork +into a helper process for privileged operations (pty handling on some +systems, utmp/wtmp/lastlog handling on others) and drop privileges +immediately. This is much safer than most other terminals that keep +privileges while running (but is more relevant to urxvt, as it contains +things as perl interpreters, which might be "helpful" to attackers). + +This forking is done as the very first within main(), which is very early +and reduces possible bugs to initialisation code run before main(), or +things like the dynamic loader of your system, which should result in very +little risk. + +=head3 On Solaris 9, many line-drawing characters are too wide. + +Seems to be a known bug, read +L. Some people use the +following ugly workaround to get non-double-wide-characters working: + + #define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x) + +=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all. + +Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined +in your compile environment, or an implementation that implements it, +whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that +B is represented as unicode. + +As you might have guessed, FreeBSD does neither define this symbol nor +does it support it. Instead, it uses its own internal representation of +B. This is, of course, completely fine with respect to standards. + +However, that means rxvt-unicode only works in C, C and +C locales under FreeBSD (which all use Unicode as B. + +C<__STDC_ISO_10646__> is the only sane way to support multi-language +apps in an OS, as using a locale-dependent (and non-standardized) +representation of B makes it impossible to convert between +B (as used by X11 and your applications) and any other encoding +without implementing OS-specific-wrappers for each and every locale. There +simply are no APIs to convert B into anything except the current +locale encoding. + +Some applications (such as the formidable B) work around this +by carrying their own replacement functions for character set handling +with them, and either implementing OS-dependent hacks or doing multiple +conversions (which is slow and unreliable in case the OS implements +encodings slightly different than the terminal emulator). + +The rxvt-unicode author insists that the right way to fix this is in the +system libraries once and for all, instead of forcing every app to carry +complete replacements for them :) + +=head3 I use Solaris 9 and it doesn't compile/work/etc. + +Try the diff in F as a base. It fixes the worst +problems with C and a compile problem. + +=head3 How can I use rxvt-unicode under cygwin? + +rxvt-unicode should compile and run out of the box on cygwin, using +the X11 libraries that come with cygwin. libW11 emulation is no +longer supported (and makes no sense, either, as it only supported a +single font). I recommend starting the X-server in C<-multiwindow> or +C<-rootless> mode instead, which will result in similar look&feel as the +old libW11 emulation. + +At the time of this writing, cygwin didn't seem to support any multi-byte +encodings (you might try C), so you are likely limited +to 8-bit encodings. + +=head1 RXVT-UNICODE TECHNICAL REFERENCE + The rest of this document describes various technical aspects of B.
