RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
Meta, Features & Commandline Issues
My question isn't answered here, can I ask a human?
Before sending me mail, you could go to IRC: "irc.freenode.net",
channel "#rxvt-unicode" has some rxvt-unicode enthusiasts that might be
interested in learning about new and exciting problems (but not FAQs
:).
I use Gentoo, and I have a problem...
There are three big problems with Gentoo Linux: first of all, most if
not all Gentoo systems are completely broken (missing or mismatched
header files, broken compiler etc. are just the tip of the iceberg);
secondly, the Gentoo maintainer thinks it is a good idea to add broken
patches to the code; and lastly, it should be called Gentoo GNU/Linux.
For these reasons, it is impossible to support rxvt-unicode on Gentoo.
Problems appearing on Gentoo systems will usually simply be ignored
unless they can be reproduced on non-Gentoo systems.
Does it support tabs, can I have a tabbed rxvt-unicode?
Beginning with version 7.3, there is a perl extension that implements a
simple tabbed terminal. It is installed by default, so any of these
should give you tabs:
urxvt-pe tabbed
URxvt.perl-ext-common: default,tabbed
It will also work fine with tabbing functionality of many window
managers or similar tabbing programs, and its embedding-features allow
it to be embedded into other programs, as witnessed by doc/rxvt-tabbed
or the upcoming "Gtk2::URxvt" perl module, which features a tabbed
urxvt (murxvt) terminal as an example embedding application.
How do I know which rxvt-unicode version I'm using?
The version number is displayed with the usage (-h). Also the escape
sequence "ESC [ 8 n" sets the window title to the version number. When
using the urxvtc client, the version displayed is that of the daemon.
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 "--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 "--enable-unicode3" it gets
worse, as rxvt-unicode then uses 8 bytes per screen cell.
How can I start urxvtd in a race-free way?
Try "urxvtd -f -o", which tells urxvtd to open the display, create the
listening socket and then fork.
How can I start urxvtd automatically when I run urxvtc?
If you want to start urxvtd automatically whenever you run urxvtc and
the daemon isn't running yet, use this script:
#!/bin/sh
urxvtc "$@"
if [ $? -eq 2 ]; then
urxvtd -q -o -f
urxvtc "$@"
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. Subsequent invocations of the script will re-use
the existing daemon.
How do I distinguish whether I'm running rxvt-unicode or a regular
xterm? I need this to decide about setting colours 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 colour.
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 <cblake@BBN.COM> 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
How do I compile the manual pages on my own?
You need to have a recent version of perl installed as /usr/bin/perl,
one that comes with pod2man, pod2text and pod2xhtml (from Pod::Xhtml).
Then go to the doc subdirectory and enter "make alldoc".
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 "--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 "--enable-everything" (which is 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*.
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, and 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 :)
Rendering, Font & Look and Feel Issues
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. Do read the manpage and option
descriptions for the programs mentioned and rxvt-unicode. Really, do
it!
1. Use transparent mode:
Esetroot wallpaper.jpg
urxvt-tr -tint red -sh 40
That works. If you think it doesn't, you lack transparency and tinting
support, or you are unable to read. This method requires that the
background-setting program sets the _XROOTPMAP_ID or ESETROOT_PMAP_ID
property. Compatible programs are Esetroot, hsetroot and feh.
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.jpg
urxvt-pixmap "background.jpg;:root"
That works. If you think it doesn't, you lack libAfterImage or GDK-
PixBuf support, or you are unable to read.
3. Use an ARGB visual:
urxvt-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 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.
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 "-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.
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 ("TERM=rxvt-unicode"), 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
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 "rxvt-unicode" terminfo
definition to only claim 8 colour support or use "TERM=rxvt", which
will fix colours but keep you from using other rxvt-unicode features.
Can I switch the fonts at runtime?
Yes, using an escape sequence. Try something like this, which has the
same effect as using the "-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.
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 "xft:Bitstream Vera Sans
Mono" 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
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 ":antialias=false"), which saves lots of
memory and also speeds up rendering considerably.
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.
What's with this bold/blink stuff?
If no bold colour is set via "colorBD:", bold will invert text using
the standard foreground colour.
For the standard background colour, blinking will actually make the
text blink when compiled with "--enable-text-blink". Without
"--enable-text-blink", the blink attribute will be ignored.
On ANSI colours, bold/blink attributes are used to set high-intensity
foreground/background colours.
color0-7 are the low-intensity colours.
color8-15 are the corresponding high-intensity colours.
I don't like the screen colours. How do I change them?
You can change the screen colours at run-time using ~/.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 colours.
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".
Why do some characters look so much different than others?
See next entry.
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.
rxvt-unicode 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-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.
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
"Can I switch the fonts at runtime?" later in this document).
How can I make mplayer display video correctly?
We are working on it, in the meantime, as a workaround, use something
like:
urxvt-b 600 -geometry 20x1 -e sh -c 'mplayer -wid $WINDOWID file...'
Keyboard, Mouse & User Interaction
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 LeftClick Shift-LeftClick combination also
selects words like the old code.
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 perl-ext-
common 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 PREPACKAGED EXTENSIONS in the urxvtperl(3) manpage. For
example, to disable the selection-popup and option-popup, specify this
perl-ext-common 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 M-s. You can move it to any
other combination either by setting the searchable-scrollback resource:
URxvt.searchable-scrollback: CM-s
The cursor moves when selecting text in the current input line, how do
I switch this off?
See next entry.
During rlogin/ssh/telnet/etc. sessions, clicking near the cursor
outputs strange escape sequences, how do I fix this?
These are caused by the "readline" 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 "readline"
extension:
URxvt.perl-ext-common: default,-readline
My numerical keypad acts weird and generates differing output?
Some Debian GNU/Linux users seem to have this problem, although no
specific details were reported so far. See the answer to the previous
question, and please report if that helped.
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 preeditStyle that is not supported by
your input method. For example, if you specified OverTheSpot 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 preeditStyle or specify more than
one pre-edit style, such as OverTheSpot,Root,None.
If it still doesn't work, then maybe your input method doesn't support
compose sequences - to fall back to the built-in one, make sure you
don't specify an input method via "-im" or "XMODIFIERS".
I cannot type "Ctrl-Shift-2" to get an ASCII NUL character due to ISO
14755
Either try "Ctrl-2" alone (it often is mapped to ASCII NUL even on
international keyboards) or simply use ISO 14755 support to your
advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for
other codes, too, such as "Ctrl-Shift-1-d" to type the default telnet
escape character and so on.
Mouse cut/paste suddenly no longer works.
Make sure that mouse reporting is actually turned off since killing
some editors prematurely may leave it active. I've heard that tcsh may
use mouse reporting unless it is otherwise specified. A quick check is
to see if cut/paste works when the Alt or Shift keys are pressed.
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: "^H" and "^?".
Historically, either value is correct, but rxvt-unicode adopts the
debian policy of using "^?" when unsure, because it's the one and only
correct choice :).
It is possible to toggle between "^H" and "^?" with the DECBKM private
mode:
# use Backspace = ^H
$ stty erase ^H
$ echo -n "^[[?67h"
# use Backspace = ^?
$ stty erase ^?
$ echo -n "^[[?67l"
This helps satisfy some of the Backspace discrepancies that occur, but
if you use Backspace = "^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 ("ESC [ 3 ~") 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.
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 "--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 "urxvt -name URxvt"
URxvt.keysym.Prior: \033[5~
URxvt.keysym.Next: \033[6~
URxvt.keysym.Home: \033[7~
URxvt.keysym.End: \033[8~
URxvt.keysym.Up: \033[A
URxvt.keysym.Down: \033[B
URxvt.keysym.Right: \033[C
URxvt.keysym.Left: \033[D
See some more examples in the documentation for the keysym resource.
I'm using keyboard model XXX that has extra Prior/Next/Insert keys. How
do I make use of them? For example, the Sun Keyboard type 4 has the
following map
KP_Insert == Insert
F22 == Print
F27 == Home
F29 == Prior
F33 == End
F35 == Next
Rather than have rxvt-unicode try to accommodate all the various
possible keyboard mappings, it is better to use `xmodmap' to remap the
keys as required for your particular machine.
Terminal Configuration
Can I see a typical configuration?
The default configuration tries to be xterm-like, which I don't like
that much, but it's least surprise to regular users.
As a rxvt or rxvt-unicode user, you are practically supposed to invest
time into customising your terminal. To get you started, here is the
author's .Xdefaults entries, with comments on what they do. It's
certainly not typical, but what's typical...
URxvt.cutchars: "()*,<>[]{}|'
URxvt.print-pipe: cat >/tmp/xxx
These are just for testing stuff.
URxvt.imLocale: ja_JP.UTF-8
URxvt.preeditType: OnTheSpot,None
This tells rxvt-unicode to use a special locale when communicating with
the X Input Method, and also tells it to only use the OnTheSpot pre-
edit type, which requires the "xim-onthespot" perl extension but
rewards me with correct-looking fonts.
URxvt.perl-lib: /root/lib/urxvt
URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
URxvt.selection.pattern-0: ( at .*? line \\d+)
URxvt.selection.pattern-1: ^(/[^:]+):\
URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
This is my perl configuration. The first two set the perl library
directory and also tells urxvt to use a large number of extensions. I
develop for myself mostly, so I actually use most of the extensions I
write.
The selection stuff mainly makes the selection perl-error-message aware
and tells it to convert perl error messages into vi-commands to load
the relevant file and go to the error line number.
URxvt.scrollstyle: plain
URxvt.secondaryScroll: true
As the documentation says: plain is the preferred scrollbar for the
author. The "secondaryScroll" configures urxvt to scroll in full-screen
apps, like screen, so lines scrolled out of screen end up in urxvt's
scrollback buffer.
URxvt.background: #000000
URxvt.foreground: gray90
URxvt.color7: gray90
URxvt.colorBD: #ffffff
URxvt.cursorColor: #e0e080
URxvt.throughColor: #8080f0
URxvt.highlightColor: #f0f0f0
Some colours. Not sure which ones are being used or even non-defaults,
but these are in my .Xdefaults. Most notably, they set
foreground/background to light gray/black, and also make sure that the
colour 7 matches the default foreground colour.
URxvt.underlineColor: yellow
Another colour, makes underline lines look different. Sometimes hurts,
but is mostly a nice effect.
URxvt.geometry: 154x36
URxvt.loginShell: false
URxvt.meta: ignore
URxvt.utmpInhibit: true
Uh, well, should be mostly self-explanatory. By specifying some
defaults manually, I can quickly switch them for testing.
URxvt.saveLines: 8192
A large scrollback buffer is essential. Really.
URxvt.mapAlert: true
The only case I use it is for my IRC window, which I like to keep
iconified till people msg me (which beeps).
URxvt.visualBell: true
The audible bell is often annoying, especially when in a crowd.
URxvt.insecure: true
Please don't hack my mutt! Ooops...
URxvt.pastableTabs: false
I once thought this is a great idea.
urxvt.font: 9x15bold,\
-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
[codeset=JISX0208]xft:Kochi Gothic, \

xft:Code2000:antialias=false
urxvt.boldFont: -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
overwhelmed. A special note: the "9x15bold" mentioned above is actually
the version from XFree-3.3, as XFree-4 replaced it by a totally
different font (different glyphs for ";" and many other harmless
characters), while the second font is actually the "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 "urxvt" instance name and not the "URxvt"
class name. That is because I use different configs for different
purposes, for example, my IRC window is started with "-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
"Alt-Ctrl-1" and "Alt-Ctrl-2" switch between two different font sizes.
"suxuseuro" 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 ".Xdefaults" (I don't use ".Xresources" nor
"xrdb"). I also have some resources in a separate ".Xdefaults-hostname"
file for different hosts, for example, on my 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 :->
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 $HOME/.Xdefaults when no resources are attached to the display.
If you have or use an $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 xrdb -merge $HOME/.Xresources).
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.
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 by simply installing rxvt-unicode on the remote system as
well (in case you have a nice package manager ready), or you can
install the terminfo database manually like this (with ncurses infocmp.
works as user and root):
REMOTE=remotesystem.domain
infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
One some systems you might need to set $TERMINFO to the full path of
$HOME/.terminfo for this to work. Debian systems have a broken tic
which will not be able to overwrite the existing rxvt-unicode terminfo
entry - you might have to manually delete all traces of rxvt-unicode*
from /etc/terminfo.
If you cannot or do not want to do this, then you can simply set
"TERM=rxvt" or even "TERM=xterm", 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 rxvt (quite common...) you could also replace
the rxvt terminfo file with the rxvt-unicode one and use "TERM=rxvt".
nano fails with "Error opening terminal: rxvt-unicode"
This exceptionally confusing and useless error message is printed by
nano when it can't find the terminfo database. Nothing is wrong with
your terminal, read the previous answer for a solution.
"tic" outputs some error when compiling the terminfo entry.
Most likely it's the empty definition for "enacs=". Just replace it by
"enacs=\E[0@" and try again.
"bash"'s readline does not work correctly under urxvt.
See next entry.
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 "rxvt-unicode".
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 the termcap entry in doc/etc/rxvt-unicode.termcap,
generated by the command above.
Why does "ls" no longer have coloured output?
The "ls" 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, "rxvt-unicode" is not in its default file (among
with most other terminals supporting colour). Either add:
TERM rxvt-unicode
to "/etc/DIR_COLORS" or simply add:
alias ls='ls --color=auto'
to your ".profile" or ".bashrc".
Encoding / Locale / Input Method Issues
Rxvt-unicode does not seem to understand the selected encoding?
See next entry.
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 "LC_CTYPE" setting as the
programs running in it. 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. "en_GB.UTF-8". Needless to
say, this is not going to work, and is the most common cause for
problems.
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" # $LANG or $LC_ALL are worth a try, too
If this doesn't work, then maybe you use a "LC_CTYPE" specification not
supported on your systems. Some systems have a "locale" command which
displays this (also, "perl -e0" 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 :(
How does rxvt-unicode determine the encoding to use?
See next entry.
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 locale.
Applications not using that info will have problems (for example,
"xterm" gets the width of characters wrong as it uses its own, locale-
independent table under all locales).
Rxvt-unicode uses the "LC_CTYPE" 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 "LC_CTYPE" environment variable
contains an arbitrary string which corresponds to an already-installed
locale. Common names for locales are "en_US.UTF-8",
"de_DE.ISO-8859-15", "ja_JP.EUC-JP", i.e. "language_country.encoding",
but other forms (i.e. "de" or "german") are also common.
Rxvt-unicode ignores all other locale categories, and except for the
encoding, ignores country or language-specific settings, i.e.
"de_DE.UTF-8" and "ja_JP.UTF-8" 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 "LC_CTYPE" category.
Can I switch locales at runtime?
Yes, using an escape sequence. Try something like this, which sets
rxvt-unicode's idea of "LC_CTYPE".
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. "de_DE.UTF-8") but some programs don't support it (e.g.
UTF-8). For example, I use this script to start "xjdic", 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 "luit" program, which usually works fine,
except for some locales where character width differs between program-
and rxvt-unicode-locales.
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:
- Make sure your locale and the imLocale are supported on your OS.
Try "locale -a" or check the documentation for your OS.
- Make sure your locale or imLocale matches a locale supported by your
XIM.
For example, kinput2 does not support UTF-8 locales, you should use
"ja_JP.EUC-JP" or equivalent.
- Make sure your XIM server is actually running.
- Make sure the "XMODIFIERS" environment variable is set correctly when
starting rxvt-unicode.
When you want to use e.g. kinput2, it must be set to "@im=kinput2".
For scim, use "@im=SCIM". You can see what input method servers are
running with this command:
xprop -root XIM_SERVERS
My input method wants <some encoding> 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 "imlocale":
URxvt.imlocale: ja_JP.EUC-JP
Now you can start your terminal with "LC_CTYPE=ja_JP.UTF-8" and still
use your input method. Please note, however, that, depending on your
Xlib version, you may not be able to input characters outside "EUC-JP"
in a normal way then, as your input method limits you.
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. kinput2 (and derived input methods) generally succeeds,
while SCIM (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.
Operating Systems / Package Maintaining
I am using Debian GNU/Linux and have a problem...
Before reporting a bug to the original rxvt-unicode author please
download and install the genuine version
(http://software.schmorp.de/pkg/rxvt-unicode.html
<http://software.schmorp.de/pkg/rxvt-unicode.html>) 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 "reportbug" 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.
I am maintaining rxvt-unicode for distribution/OS XXX, any
recommendation?
You should build one binary with the default options. configure 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 "perl-ext-common" and "perl-ext" resources
system-wide (except maybe with "defaults"). This will result in useful
behaviour. If your distribution aims at low memory, add an empty
"perl-ext-common" 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 "--disable-everything" (very useful) and a maximal one with
"--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).
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.
I am on FreeBSD and rxvt-unicode does not seem to work at all.
Rxvt-unicode requires the symbol "__STDC_ISO_10646__" to be defined in
your compile environment, or an implementation that implements it,
whether it defines the symbol or not. "__STDC_ISO_10646__" requires
that wchar_t 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
wchar_t. This is, of course, completely fine with respect to standards.
However, that means rxvt-unicode only works in "POSIX", "ISO-8859-1"
and "UTF-8" locales under FreeBSD (which all use Unicode as wchar_t).
"__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 wchar_t makes it impossible to convert between
wchar_t (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 wchar_t into anything except the
current locale encoding.
Some applications (such as the formidable mlterm) 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 :)
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 "-multiwindow" or
"-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 "LC_CTYPE=C-UTF-8"), so you are likely
limited to 8-bit encodings.
Character widths are not correct.
urxvt uses the system wcwidth function to know the information about
the width of characters, so on systems with incorrect locale data you
will likely get bad results. Two notorious examples are Solaris 9,
where single-width characters like U+2514 are reported as double-width,
and Darwin 8, where combining chars are reported having width 1.
The solution is to upgrade your system or switch to a better one. A
possibly working workaround is to use a wcwidth implementation like
http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

"Pm = 1015" (rxvt-unicode) (Compile frills)
Changes all mouse reporting codes to use decimal parameters
instead of octets or characters.
This mode should be enabled before actually enabling mouse
reporting, for semi-obvious reasons.
The sequences received for various modes are as follows:
ESC [ M o o o !1005, !1015 (three octets)
ESC [ M c c c 1005, !1015 (three characters)
ESC [ Pm M 1015 (three or more numeric parameters)
The first three parameters are "code", "x" and "y". Code is the
numeric code as for the other modes (but encoded as a decimal
number, including the additional offset of 32, so you have to
subtract 32 first), "x" and "y" are the coordinates (1|1 is the
upper left corner, just as with cursor positioning).
Example: Shift-Button-1 press at top row, column 80.
ESC [ 37 ; 80 ; 1 M
One can use this feature by simply enabling it and then looking
for parameters to the "ESC [ M" reply - if there are any, this
mode is active, otherwise one of the old reporting styles is
used.
Other (to be implemented) reply sequences will use a similar
encoding.
In the future, more parameters might get added (pixel
coordinates for example - anybody out there who needs this?).
h Enable new mouse coordinate reporting.

3 button released (X11 mouse report)
The upper bits of "<b>" indicate the modifiers when the button was
pressed and are added together (X11 mouse report only):
State = "(<b> - SPACE) & ~3"
4 Shift
8 Meta
16 Control
32 Motion Notify
32 Double Click (rxvt extension), disabled by default
64 Button1 is actually Button4, Button2 is actually Button5 etc.

CONFIGURE OPTIONS
General hint: if you get compile errors, then likely your configuration
hasn't been tested well. Either try with "--enable-everything" or use
the default configuration (i.e. no "--enable-xxx" or "--disable-xxx"
switches). Of course, you should always report when a combination
doesn't work, so it can be fixed. Marc Lehmann <rxvt@schmorp.de>.
All
--enable-everything
Add (or remove) support for all non-multichoice options listed in
"./configure --help", except for "--enable-assert" and
"--enable-256-color".
You can specify this and then disable options you do not like by
following this with the appropriate "--disable-..." arguments, or
you can start with a minimal configuration by specifying
"--disable-everything" and than adding just the "--enable-..."
arguments you want.
--enable-xft (default: on)
Add support for Xft (anti-aliased, among others) fonts. Xft fonts
are slower and require lots of memory, but as long as you don't use
them, you don't pay for them.
--enable-font-styles (default: on)
Add support for bold, italic and bold italic font styles. The fonts
can be set manually or automatically.
--with-codesets=CS,... (default: all)
Compile in support for additional codeset (encoding) groups ("eu",
"vn" are always compiled in, which includes most 8-bit character
sets). These codeset tables are used for driving X11 core fonts,
they are not required for Xft fonts, although having them compiled
in lets rxvt-unicode choose replacement fonts more intelligently.
Compiling them in will make your binary bigger (all of together
cost about 700kB), but it doesn't increase memory usage unless you
use a font requiring one of these encodings.
all all available codeset groups
zh common chinese encodings
zh_ext rarely used but very big chinese encodings
jp common japanese encodings
jp_ext rarely used but big japanese encodings
kr korean encodings
--enable-xim (default: on)
Add support for XIM (X Input Method) protocol. This allows using
alternative input methods (e.g. kinput2) and will also correctly
set up the input for people using dead keys or compose keys.
--enable-unicode3 (default: off)
Recommended to stay off unless you really need non-BMP characters.
Enable direct support for displaying unicode codepoints above 65535
(the basic multilingual page). This increases storage requirements
per character from 2 to 4 bytes. X11 fonts do not yet support these
extra characters, but Xft does.
Please note that rxvt-unicode can store unicode code points >65535
even without this flag, but the number of such characters is
limited to a few thousand (shared with combining characters, see
next switch), and right now rxvt-unicode cannot display them
(input/output and cut&paste still work, though).
--enable-combining (default: on)
Enable automatic composition of combining characters into composite
characters. This is required for proper viewing of text where
accents are encoded as separate unicode characters. This is done by
using precomposed characters when available or creating new pseudo-
characters when no precomposed form exists.
Without --enable-unicode3, the number of additional precomposed
characters is somewhat limited (the 6400 private use characters
will be (ab-)used). With --enable-unicode3, no practical limit
exists.
This option will also enable storage (but not display) of
characters beyond plane 0 (>65535) when --enable-unicode3 was not
specified.
The combining table also contains entries for arabic presentation
forms, but these are not currently used. Bug me if you want these
to be used (and tell me how these are to be used...).
--enable-fallback[=CLASS] (default: Rxvt)
When reading resource settings, also read settings for class CLASS.
To disable resource fallback use --disable-fallback.
--with-res-name=NAME (default: urxvt)
Use the given name as default application name when reading
resources. Specify --with-res-name=rxvt to replace rxvt.
--with-res-class=CLASS (default: URxvt)
Use the given class as default application class when reading
resources. Specify --with-res-class=Rxvt to replace rxvt.
--enable-utmp (default: on)
Write user and tty to utmp file (used by programs like w) at start
of rxvt execution and delete information when rxvt exits.
--enable-wtmp (default: on)
Write user and tty to wtmp file (used by programs like last) at
start of rxvt execution and write logout when rxvt exits. This
option requires --enable-utmp to also be specified.
--enable-lastlog (default: on)
Write user and tty to lastlog file (used by programs like
lastlogin) at start of rxvt execution. This option requires
--enable-utmp to also be specified.
--enable-afterimage (default: off)
Add support for libAfterImage to be used for background images. It
adds support for many file formats including JPG, PNG, SVG, TIFF,
GIF, XPM, BMP, ICO, XCF, TGA and AfterStep image XML
(<http://www.afterstep.org/visualdoc.php?show=asimagexml>).
Note that with this option enabled, urxvt's memory footprint might
increase by a few megabytes even if no extra features are used
(mostly due to third-party libraries used by libAI). Memory
footprint may somewhat be lowered if libAfterImage is configured
without support for SVG.
--enable-pixbuf (default: on)
Add support for GDK-PixBuf to be used for background images. It
adds support for many file formats including JPG, PNG, TIFF, GIF,
XPM, BMP, ICO and TGA.
--enable-startup-notification (default: on)
Add support for freedesktop startup notifications. This allows
window managers to display some kind of progress indicator during
startup.
--enable-transparency (default: on)
Add support for using the root pixmap as background to simulate
transparency. Note that blur and blend effects depend on
libAfterImage or on libXrender and on the availability of the
RENDER extension in the X server.
--enable-fading (default: on)
Add support for fading the text when focus is lost.
--enable-rxvt-scroll (default: on)
Add support for the original rxvt scrollbar.
--enable-next-scroll (default: on)
Add support for a NeXT-like scrollbar.
--enable-xterm-scroll (default: on)
Add support for an Xterm-like scrollbar.
--disable-backspace-key
Removes any handling of the backspace key by us - let the X server
do it.
--disable-delete-key
Removes any handling of the delete key by us - let the X server do
it.
--disable-resources
Removes any support for resource checking.
--disable-swapscreen
Remove support for secondary/swap screen.
--enable-frills (default: on)
Add support for many small features that are not essential but nice
to have. Normally you want this, but for very small binaries you
may want to disable this.
A non-exhaustive list of features enabled by "--enable-frills"
(possibly in combination with other switches) is:
MWM-hints
EWMH-hints (pid, utf8 names) and protocols (ping)
urgency hint
separate underline colour (-underlineColor)
settable border widths and borderless switch (-w, -b, -bl)
visual depth selection (-depth)
settable extra linespacing (-lsp)
iso-14755 5.1 (basic) support
tripleclickwords (-tcw)
settable insecure mode (-insecure)
keysym remapping support
cursor blinking and underline cursor (-bc, -uc)
XEmbed support (-embed)
user-pty (-pty-fd)
hold on exit (-hold)
compile in built-in block graphics
skip builtin block graphics (-sbg)
separate highlight colour (-highlightColor, -highlightTextColor)
extended mouse reporting modes (1005 and 1015).
It also enables some non-essential features otherwise disabled,
such as:
some round-trip time optimisations
nearest colour allocation on pseudocolor screens
UTF8_STRING support for selection
sgr modes 90..97 and 100..107
backindex and forwardindex escape sequences
view change/zero scrollback escape sequences
locale switching escape sequence
window op and some xterm/OSC escape sequences
rectangular selections
trailing space removal for selections
verbose X error handling
--enable-iso14755 (default: on)
Enable extended ISO 14755 support (see urxvt(1)). Basic support
(section 5.1) is enabled by "--enable-frills", while support for
5.2, 5.3 and 5.4 is enabled with this switch.
--enable-keepscrolling (default: on)
Add support for continual scrolling of the display when you hold
the mouse button down on a scrollbar arrow.
--enable-selectionscrolling (default: on)
Add support for scrolling when the selection moves to the top or
bottom of the screen.
--enable-mousewheel (default: on)
Add support for scrolling via mouse wheel or buttons 4 & 5.
--enable-slipwheeling (default: on)
Add support for continual scrolling (using the mouse wheel as an
accelerator) while the control key is held down. This option
requires --enable-mousewheel to also be specified.
--enable-smart-resize (default: off)
Add smart growth/shrink behaviour when resizing. This should keep
the window corner which is closest to a corner of the screen in a
fixed position.
--enable-text-blink (default: on)
Add support for blinking text.
--enable-pointer-blank (default: on)
Add support to have the pointer disappear when typing or inactive.
--enable-perl (default: on)
Enable an embedded perl interpreter. See the urxvtperl(3) manpage
for more info on this feature, or the files in src/perl/ for the
extensions that are installed by default. The perl interpreter
that is used can be specified via the "PERL" environment variable
when running configure. Even when compiled in, perl will not be
initialised when all extensions have been disabled "-pe ""
--perl-ext-common """, so it should be safe to enable from a
resource standpoint.
--enable-assert (default: off)
Enables the assertions in the code, normally disabled. This switch
is only useful when developing rxvt-unicode.
--enable-256-color (default: off)
Force use of so-called 256 colour mode, to work around buggy
applications that do not support termcap/terminfo, or simply
improve support for applications hardcoding the xterm 256 colour
table.
This switch breaks termcap/terminfo compatibility to
"TERM=rxvt-unicode", and consequently sets "TERM" to
"rxvt-unicode-256color" by default (doc/etc/ contains
termcap/terminfo definitions for both).
It also results in higher memory usage and can slow down urxvt
dramatically when more than six fonts are in use by a terminal
instance.
--with-afterimage-config=DIR
Look for the libAfterImage config script in DIR.
--with-name=NAME (default: urxvt)
Set the basename for the installed binaries, resulting in "urxvt",
"urxvtd" etc.). Specify "--with-name=rxvt" to replace with "rxvt".
--with-term=NAME (default: rxvt-unicode)
Change the environmental variable for the terminal to NAME.
--with-terminfo=PATH
Change the environmental variable for the path to the terminfo tree
to PATH.
--with-x
Use the X Window System (pretty much default, eh?).
