		40	There are two big problems with Gentoo Linux: first, most if not all
		41	Gentoo systems are completely broken (missing or mismatched header
		42	files, broken compiler etc. are just the tip of the iceberg);
		43	secondly, it should be called Gentoo GNU/Linux.
		44
		45	For these reasons, it is impossible to support rxvt-unicode on
		46	Gentoo. Problems appearing on Gentoo systems will usually simply be
		47	ignored unless they can be reproduced on non-Gentoo systems.

79		93
		94	If you want to start @@URXVT_NAME@@d automatically whenever you run
		95	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		96
		97	#!/bin/sh
		98	@@URXVT_NAME@@c "$@"
		99	if [ $? -eq 2 ]; then
		100	@@URXVT_NAME@@d -q -o -f
		101	@@URXVT_NAME@@c "$@"
		102	fi
		103
		104	This tries to create a new terminal, and if fails with exit status 2,
		105	meaning it couldn't connect to the daemon, it will start the daemon and
		106	re-run the command. Subsequent invocations of the script will re-use the
		107	existing daemon.

242	=head3 Why do some chinese characters look so different than others?
243
244	This is because there is a difference between script and language --
245	rxvt-unicode does not know which language the text that is output is,
246	as it only knows the unicode character codes. If rxvt-unicode first
247	sees a japanese/chinese character, it might choose a japanese font for
248	display. Subsequent japanese characters will use that font. Now, many
249	chinese characters aren't represented in japanese fonts, so when the first
250	non-japanese character comes up, rxvt-unicode will look for a chinese font
251	-- unfortunately at this point, it will still use the japanese font for
252	chinese characters that are also in the japanese font.
253
254	The workaround is easy: just tag a chinese font at the end of your font
255	list (see the previous question). The key is to view the font list as
256	a preference list: If you expect more japanese, list a japanese font
257	first. If you expect more chinese, put a chinese font first.
258
259	In the future it might be possible to switch language preferences at
260	runtime (the internal data structure has no problem with using different
261	fonts for the same character at the same time, but no interface for this
262	has been designed yet).
263
264	Until then, you might get away with switching fonts at runtime (see L<Can
265	I switch the fonts at runtime?> later in this document).

		457	=head3 Why do some chinese characters look so different than others?
		458
		459	This is because there is a difference between script and language --
		460	rxvt-unicode does not know which language the text that is output is,
		461	as it only knows the unicode character codes. If rxvt-unicode first
		462	sees a japanese/chinese character, it might choose a japanese font for
		463	display. Subsequent japanese characters will use that font. Now, many
		464	chinese characters aren't represented in japanese fonts, so when the first
		465	non-japanese character comes up, rxvt-unicode will look for a chinese font
		466	-- unfortunately at this point, it will still use the japanese font for
		467	chinese characters that are also in the japanese font.
		468
		469	The workaround is easy: just tag a chinese font at the end of your font
		470	list (see the previous question). The key is to view the font list as
		471	a preference list: If you expect more japanese, list a japanese font
		472	first. If you expect more chinese, put a chinese font first.
		473
		474	In the future it might be possible to switch language preferences at
		475	runtime (the internal data structure has no problem with using different
		476	fonts for the same character at the same time, but no interface for this
		477	has been designed yet).
		478
		479	Until then, you might get away with switching fonts at runtime (see L<Can

644	=head2 Terminal Configuration	659	=head2 Terminal Configuration
		660
		661	=head3 Can I see a typical configuration?
		662
		663	The default configuration tries to be xterm-like, which I don't like that
		664	much, but it's least surprise to regular users.
		665
		666	As a rxvt or rxvt-unicode user, you are practically supposed to invest
		667	time into customising your terminal. To get you started, here is the
		668	author's .Xdefaults entries, with comments on what they do. It's certainly
		669	not I<typical>, but what's typical...
		670
		671	URxvt.cutchars: "()*,<>[]{}|'
		672	URxvt.print-pipe: cat >/tmp/xxx
		673
		674	These are just for testing stuff.
		675
		676	URxvt.imLocale: ja_JP.UTF-8
		677	URxvt.preeditType: OnTheSpot,None
		678
		679	This tells rxvt-unicode to use a special locale when communicating with
		680	the X Input Method, and also tells it to only use the OnTheSpot pre-edit
		681	type, which requires the C<xim-onthespot> perl extension but rewards me
		682	with correct-looking fonts.
		683
		684	URxvt.perl-lib: /root/lib/urxvt
		685	URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard
		686	URxvt.selection.pattern-0: ( at .*? line \\d+)
		687	URxvt.selection.pattern-1: ^(/[^:]+):\
		688	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		689	URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
		690
		691	This is my perl configuration. The first two set the perl library
		692	directory and also tells urxvt to use a large number of extensions. I
		693	develop for myself mostly, so I actually use most of the extensions I
		694	write.
		695
		696	The selection stuff mainly makes the selection perl-error-message aware
		697	and tells it to convert perl error messages into vi-commands to load the
		698	relevant file and go to the error line number.
		699
		700	URxvt.scrollstyle: plain
		701	URxvt.secondaryScroll: true
		702
		703	As the documentation says: plain is the preferred scrollbar for the
		704	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		705	apps, like screen, so lines scrolled out of screen end up in urxvt's
		706	scrollback buffer.
		707
		708	URxvt.background: #000000
		709	URxvt.foreground: gray90
		710	URxvt.color7: gray90
		711	URxvt.colorBD: #ffffff
		712	URxvt.cursorColor: #e0e080
		713	URxvt.throughColor: #8080f0
		714	URxvt.highlightColor: #f0f0f0
		715
		716	Some colours. Not sure which ones are being used or even non-defaults, but
		717	these are in my .Xdefaults. Most notably, they set foreground/background
		718	to light gray/black, and also make sure that the colour 7 matches the
		719	default foreground colour.
		720
		721	URxvt.underlineColor: yellow
		722
		723	Another colour, makes underline lines look different. Sometimes hurts, but
		724	is mostly a nice effect.
		725
		726	URxvt.geometry: 154x36
		727	URxvt.loginShell: false
		728	URxvt.meta: ignore
		729	URxvt.utmpInhibit: true
		730
		731	Uh, well, should be mostly self-explanatory. By specifying some defaults
		732	manually, I can quickly switch them for testing.
		733
		734	URxvt.saveLines: 8192
		735
		736	A large scrollback buffer is essential. Really.
		737
		738	URxvt.mapAlert: true
		739
		740	The only case I use it is for my IRC window, which I like to keep
		741	iconified till people msg me (which beeps).
		742
		743	URxvt.visualBell: true
		744
		745	The audible bell is often annoying, especially when in a crowd.
		746
		747	URxvt.insecure: true
		748
		749	Please don't hack my mutt! Ooops...
		750
		751	URxvt.pastableTabs: false
		752
		753	I once thought this is a great idea.
		754
		755	urxvt.font: 9x15bold,\
		756	-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
		757	-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
		758	[codeset=JISX0208]xft:Kochi Gothic, \
		759	xft:Bitstream Vera Sans Mono:autohint=true, \
		760	xft:Code2000:antialias=false
		761	urxvt.boldFont: -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
		762	urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		763	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		764
		765	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		766	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		767	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		768	font (different glyphs for C<;> and many other harmless characters),
		769	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		770	bold version has less chars than the medium version, so I use it for rare
		771	characters, too. When editing sources with vim, I use italic for comments
		772	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		773
		774	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		775	purposes, it works, and gives a different look, as my normal (Non-bold)
		776	font is already bold, and I want to see a difference between bold and
		777	normal fonts.
		778
		779	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		780	class name. That is because I use different configs for different purposes,
		781	for example, my IRC window is started with C<-name IRC>, and uses these
		782	defaults:
		783
		784	IRC*title: IRC
		785	IRC*geometry: 87x12+535+542
		786	IRC*saveLines: 0
		787	IRC*mapAlert: true
		788	IRC*font: suxuseuro
		789	IRC*boldFont: suxuseuro
		790	IRC*colorBD: white
		791	IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
		792	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		793
		794	C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
		795	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		796	stuff while keeping a very small window. If somebody pastes something
		797	complicated (e.g. japanese), I temporarily switch to a larger font.
		798
		799	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		800	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		801	file for different hosts, for example, on my main desktop, I use:
		802
		803	URxvt.keysym.C-M-q: command:\033[3;5;5t
		804	URxvt.keysym.C-M-y: command:\033[3;5;606t
		805	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		806	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		807	URxvt.keysym.C-M-p: perl:test
		808
		809	The first for keysym definitions allow me to quickly bring some windows
		810	in the layout I like most. Ion users might start laughing but will stop
		811	immediately when I tell them that I use my own Fvwm2 module for much the
		812	same effect as Ion provides, and I only very rarely use the above key
		813	combinations :->

901	unfortunately this notice has been removed). Before reporting a bug to
902	the original rxvt-unicode author please download and install the genuine

904	the problem. If you cannot, chances are that the problems are specific to
