Last updated at 2012-12-26Posted at 2012-03-16

w3m と markdown が必要。
-dump とるとインタラクティブ。

function markdown_preview(){
    if [ $# -ne 1 ]
    then
        echo "error: invalid arguments"
        echo "usage: $0 markdown_file"
        return 1
    fi

    if [ ! -f "$1" ]
    then
        echo "error: $1 dose not exists"
        return 2
    fi

    (echo '<html><head><meta charset="UTF-8" /></head><body>';
        markdown $1; echo '</body></html>')\
        | w3m -T text/html -dump

    # screen で縦割りしたときにズレる問題解決
    if [ $STY ]
    then
        sleep 0.2
        screen -X redisplay
    fi
}
