[http://github.com/muennich/sxiv sxiv] (Simple [[X]] Image Viewer) は C で書かれている軽量でスクリプト可能な画像ビューアです。

== インストール ==

[[公式リポジトリ]]の {{Pkg|sxiv}} を[[インストール]]してください。

== sxiv にキーボードショートカットを設定 ==
sxiv supports external key events. First you have to press {{ic|Ctrl-x}} to send the next key to the external key-handler. The external key-handler requires an executable file {{ic|~/.config/sxiv/exec/key-handler}} and passes the key combination pressed as well the name of the current image as arguments.

In this example, we will add the bindings {{ic|Ctrl+d}} to execute {{ic|mv ''filename'' ~/.trash}}, {{ic|Ctrl+c}} to copy the current image's name to the clipboard with {{Pkg|xclip}}, and {{ic|Ctrl+w}} to set the current wallpaper with [[nitrogen]]. 

{{hc|~/.config/sxiv/exec/key-handler|<nowiki>
#!/bin/sh

case "$1" in
"C-d")
        mv "$2" ~/.trash ;;
"C-r")
        convert -rotate 90 "$2" "$2" ;;
"C-c")
        echo -n "$2" | xclip -selection clipboard ;;
"C-w")
        nitrogen --save --set-zoom-fill "$2" ;;
esac
</nowiki>}}

Be sure to mark the script as executable
 $ chmod +x ~/.config/sxiv/exec/key-handler

Create {{ic|.trash}} folder if it does not exist:
 $ mkdir ~/.trash

{{Tip|You may want to use a [http://freedesktop.org/wiki/Specifications/trash-spec/ standards-compliant trashcan] (like {{AUR|trash-cli}} or {{AUR|bashtrash}}) rather than {{ic|mv "$2" ~/.trash}}.}}

== Tips and tricks ==

=== ファイルを開いた後にディレクトリの画像をブラウズ ===

Place [http://git.savannah.gnu.org/cgit/ranger.git/tree/doc/examples/rifle_sxiv.sh this script] in {{ic|/usr/local/bin}} and call it like this:
 $ ''scriptname'' a_single_image.jpg

Alternatively you can also install the script as a package from the AUR: {{AUR|sxiv-rifle}}. 

As indicated in the comments of the script, it may be used to have this behavior when opening images from within [[ranger]].

=== ステータスバーに画像サイズを表示 ===

Place the following executable script in {{ic|~/.config/sxiv/exec/image-info}} and make sure that you have the {{Pkg|exiv2}} package installed:

{{hc|~/.config/sxiv/exec/image-info|<nowiki>
#!/bin/sh

# Example for ~/.config/sxiv/exec/image-info
# Called by sxiv(1) whenever an image gets loaded,
# with the name of the image file as its first argument.
# The output is displayed in sxiv's status bar.

s=" | " # field separator

filename=$(basename "$1")
filesize=$(du -Hh "$1" | cut -f 1)

geometry=$(identify -format '%wx%h' "$1[0]")

tags=$(exiv2 -q pr -pi "$1" | awk '$1~"Keywords" { printf("%s,", $4); }')
tags=${tags%,}

echo "${filesize}${s}${geometry}${tags:+$s}${tags}${s}${filename}"
</nowiki>}}
