软件简介

Erubis 是一个快速、安全和具备高可扩展性的 eRuby 的实现，主要特征如下：

• 快速，几乎是 ERB 的三倍，比用C开发的eRuby还要快10%
• File caching of converted Ruby script support.
• Auto escaping (sanitizing) support, it means that ‘<%= %>’ can be escaped in default. It is desirable for web application.
• Spaces around ‘<% %>’ are trimmed automatically only when ‘<%’ is at the beginning of line and ‘%>’ is at the end of line.
• Embedded pattern changeable (default ‘<% %>’), for example ‘[% %]’ or ‘<? ?>’ are available.
• Enable to handle Processing Instructions (PI) as embedded pattern (ex. ‘<?rb … ?>’). This is desirable for XML/HTML than ‘<% .. %>’ because the latter breaks HTML design but the former doesn’t.
• Multi-language support (Ruby/PHP/C/Java/Scheme/Perl/Javascript).
• Context object available and easy to combine eRuby template with YAML datafile (see the below example).
• Print statement available.
• Easy to expand and customize in subclass
  • Print statement support
  • Lines starting with percent character (‘%’) support
  • Another embedded pattern support
  • etc…
• Ruby on Rails support.
• Mod_ruby support.
