Today I wanted to have a index.html for a directory full of DocBook articles. Being quite lazy I simply wrote a small Ruby script for doing this since I couldn’t get sed to do what I want:

#!/usr/bin/ruby -w

require 'rexml/document'

def getTitle(file)

        doc = REXML::Document.new(File.new(file))

        title = doc.elements.each("/article/title"){|t| return t.text}

        return File.filename(file)

end

puts <<EOS

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

        <title>Guides</title>

        <meta http-equiv="Content-type" content="text/html;charset=UTF-8"/>

        <link rel="stylesheet" type="text/css" href="../_s/style.css"/>

</head>

<body>

<h1>Guides</h1>

<ul>

EOS

dh = Dir.new(".")

dh.each do |f|

        next if ['.','..'].include?(f)

        path = dh.path+File::SEPARATOR+f

        indexxml = path+File::SEPARATOR+"index.xml"

        indexhtml=path+File::SEPARATOR+"index.html"

        if File.directory?(path) and File.exists?(indexxml)

                puts "<li><a href="#{indexhtml}">#{getTitle(indexxml)}</a></li>"

        end

end

puts <<EOS

</ul>

</body>

</html>

Since I’m currently learning Ruby - or let’s call it refreshing my Ruby knownledge - I’m trying to write most of the scripts I need everyday in Ruby to get some practice. Starting with today I will also post these small scripts here :)
