# XmlSitemap

XmlSitemap is a Ruby library that provides an easy way to generate XML sitemaps and indexes.

It does not have any web-framework dependencies and could be used in any ruby-based application.

## Installation

Install via rubygems:

    $ gem install xml-sitemap
  
## Configuration

Add gem to your Gemfile and you're ready to go:

```ruby
gem 'xml-sitemap'
```

## Usage
  
Simple usage:

```ruby
map = XmlSitemap::Map.new('domain.com') do |m|
  # Adds a simple page
  m.add '/page1'  

  # You can drop leading slash, it will be automatically added
  m.add 'page2'

  # Set the page priority (default is 0.5)
  m.add 'page3', :priority => 0.2

  # Specify last modification date and update frequiency
  m.add 'page4', :updated => Date.today, :period => :never
end

# Render the sitemap XML
map.render

# Render and save XML to the output file
map.render_to('/path/to/file.xml')

# You can also use compression
map.render_to('/path/to/file.xml.gz', :gzip => true)

# If you didnt specify .gz extension to the filename,
# XmlSitemap will automatically append it
# => content will be saved to /path/to/file.xml.gz
map.render_to('/path/to/file.xml', :gzip => true)
```

You can also create a map via shortcut:

```ruby
map = XmlSitemap.new('foobar.com')
map = XmlSitemap.map('foobar.com')
```
  
By default XmlSitemap creates a map with link to homepage of your domain. It's a priority 1.0. Default priority is 0.5.

List of periods:

- :none,
- :always
- :hourly
- :daily
- :weekly
- :monthly
- :yearly
- :never

## XmlSitemap::Map

When creating a new map object, you can specify a set of options.

```ruby
map = XmlSitemap::Map.new('mydomain.com', options)
```

Available options:

- :secure - Will add all sitemap items with https prefix. *(default: false)*
- :home   - Disable homepage autocreation, but you still can do that manually. *(default: true)*
- :root   - Force all links to fall under the main domain. You can add full urls (not paths) if set to false. *(default: true)*
- :time   - Provide a creation time for the sitemap. (default: current time)
- :group  - Group name for sitemap index. *(default: sitemap)* 

## XmlSitemap::Index

Regular sitemap does not support more than 50k records, so if you're generating a huge sitemap you need to use XmlSitemap::Index.

Index is just a collection of links to all the website's sitemaps.

Usage:

```ruby
map = XmlSitemap::Map.new('domain.com')
map.add 'page'
    
index = XmlSitemap::Index.new
# or via shortcut
index = XmlSitemap.index

# Add a map to the index
index.add(map)

# Render as XML
index.render

# Render XML to the output file
index.render_to('/path/to/file.xml')
```
