[http://robm.github.com/dzen/ Dzen] は X11 向けの汎用メッセージング、通知、メニュープログラムです。どの言語でもスクリプト可能なように作られており [[dwm]], [[wmii]], [[xmonad]] などのウィンドウマネージャとよく合いますが、ウィンドウマネージャならどれでも動作します。

== インストール ==

[[公式リポジトリ]]の {{Pkg|dzen2}} パッケージをインストールしてください。Xft, XPM, Xinerama のサポートが含まれています。

{{Note|Xft doesn't seem to work with the official package. Alternatively, you can install the {{AUR|dzen2-xft-xpm-xinerama-git}} package located in the [[AUR]] with Xft, XPM and Xinerama support.}}

== 設定 ==

Dzen は [[X resources]] からフォントと色の設定を読み込むことができます。例えば、以下の行を {{ic|~/.Xresources}} に追加できます:
 dzen2.font:       -*-fixed-*-*-*-*-*-*-*-*-*-*-*-*
 dzen2.foreground: #22EE11
 dzen2.background: black

== Tips and tricks ==

=== dzen でカスタムフォントを使う ===

Dzen は [[X_Logical_Font_Description|X Logical Font Description]] に従って X フォントパスにあるフォントしか使いません。詳しくは[[フォント#古いアプリケーション]]を見て下さい。

=== Dzen と Conky ===

[[Conky]] can be used to pipe information directly to dzen for output in a status bar.  
This can be done with Conky in the official repositories and also with {{AUR|conky-cli}}, a stripped-down version of the Conky status utility from the [[Arch User Repository|AUR]].

The following example displays the average load values in red and the current time in the default dzen foreground colour:

{{hc|~/.conkyrc|<nowiki>
 background no
 out_to_console yes
 out_to_x no
 update_interval 1.0
 total_run_times 0
 use_spacer none
 
 TEXT
 ^fg(\#ff0000)${loadavg 1 2 3} ^fg()${time %a %b %d %I:%M%P}
</nowiki>}}

{{hc|~/bin/dzconky|<nowiki>
 #!/bin/sh
 
 FG='#aaaaaa'
 BG='#1a1a1a'
 FONT='-*-terminus-*-r-normal-*-*-120-*-*-*-*-iso8859-*'
 conky | dzen2 -e - -h '16' -w '600' -ta r -fg $FG -bg $BG -fn $FONT &
</nowiki>}}
Simply execute {{ic|dzconky}} in your startup scripts.

=== クリッカブルエリアとポップアップ ===

dzen2 allows you to define clickable areas using {{ic|^ca(''button'', ''command'')Text^ca()}}.
You can use this property to create popups giving arbitrary information, as seen in various screenshot gifs like [http://i.minus.com/ibzmjKMXKk7IbH.gif this] and [http://paste.unixhub.net/index.php/NlKe/ this].

A simple example can be:
{{hc|sysinfo_popup.sh|<nowiki>
 #/bin/bash

 #A simple popup showing system information

 HOST=$(uname -n)
 KERNEL=$(uname -r)
 UPTIME=$( uptime | sed 's/.* up //' | sed 's/[0-9]* us.*//' | sed 's/ day, /d /'\
          | sed 's/ days, /d /' | sed 's/:/h /' | sed 's/ min//'\
            |  sed 's/,/m/' | sed 's/  / /')
 PACKAGES=$(pacman -Q | wc -l)
 UPDATED=$(awk '/upgraded/ {line=$0;} END { $0=line; gsub(/[\[\]]/,"",$0); \
          printf "%s %s",$1,$2;}' /var/log/pacman.log)

 (
 echo "System Information" # Fist line goes to title
 # The following lines go to slave window
 echo "Host: $HOST "
 echo "Kernel: $KERNEL"
 echo "Uptime: $UPTIME "
 echo "Pacman: $PACKAGES packages"
 echo "Last updated on: $UPDATED"
 ) | dzen2 -p -x "500" -y "30" -w "220" -l "5" -sa 'l' -ta 'c'\
    -title-name 'popup_sysinfo' -e 'onstart=uncollapse;button1=exit;button3=exit'

 # "onstart=uncollapse" ensures that slave window is visible from start.
</nowiki>}}
Save this script and make it executable and then use the {{ic|^ca()}} attribute in your conkyrc (or the script that you pipe to dzen2) to trigger it.
 {{ic|^ca(1,''<path to your script>'')Sysinfo^ca()}}

This will bind the script to mouse button 1 and execute it when it is clicked over the text.

=== dzen の Xft サポートを有効にする ===

{{Note|You need to install the {{Pkg|libxft}} package.}}

As of SVN revision 241 (development), dzen2 has optional support for Xft. To enable Xft support, build dzen2 with these options by editing {{ic|config.mk}}:

{{hc|config.mk|<nowiki>
 ## Option: With Xinerama and XPM and XFT
 LIBS = -L/usr/lib -lc -L${X11LIB} -lX11 -lXinerama -lXpm $(pkg-config --libs xft)
 CFLAGS = -Wall -Os ${INCS} -DVERSION=\"${VERSION}\" -DDZEN_XINERAMA -DDZEN_XPM -DDZEN_XFT $(pkg-config --cflags xft)
</nowiki>}}

To check libxft support, you can use this command:
 echo "hello world" | dzen2 -fn 'Times New Roman' -p
