Hi all, I have released Tenjin 0.6.1. [http://www.kuwata-lab.com/tenjin/](http://www.kuwata-lab.com/tenjin/) changes: [http://www.kuwata-lab.com/tenjin/rbtenjin-CHANGES.txt](http://www.kuwata-lab.com/tenjin/rbtenjin-CHANGES.txt) Tenjin is a fast and full-featured template engine similar to eRuby but it has the following advantages against to eRuby and ERB. - Very fast (twice faster than eruby and three times faster than ERB) - Lightweight (only one file which contains about 1000 lines) - Not break HTML design because it uses XML Processing Instructions (PI) as embedded notation for Python statements. - Secure because it supports escaping expression value by default. - Auto caching of converted Python code. - Nestable layout template - Inlucde other templates - Capture part of template - Load YAML file as context data - Preprocessing support Notation of Tenjin is different from eRuby. - ‘\’ represents Ruby statements. - ‘#{…}’ represents Ruby expression. - ‘${…}’ represents Ruby expression with escaping (sanitizing). ## ex. example.rbhtml \ \ | #{item} | ${item} | ---------- # ex. convert into Ruby script $ rbtenjin -s example.rbhtml \_buf = ‘’; \_buf \<\< %Q` \n` for item in @items _buf \<\< %Q` \n` end _buf \<\< %Q` | #{item} | #{escape((item).to\_s)} | \n` \_buf.to\_s ========== # ex. execute converted Ruby script $ rbtenjin -c ‘@items=%w[B&B “CCC”]’ example.rbhtml | | \ | | B&B | B&B | | "CCC" | "CCC" | ========== Tenjin is more suitable for web applications than eRuby, because it doesn’t break HTML desing of template and supports partial template and layout temlate. See Tenjin User’s Guide for details. [http://www.kuwata-lab.com/tenjin/rbtenjin-users-guide.html](http://www.kuwata-lab.com/tenjin/rbtenjin-users-guide.html) Enhancements from 0.6.0: - It is able to make any class which includes Tenjin::ContextHelper module as context object class. This is useful if you want to define helper functions as instance method of that class. See section ‘Add Your Helper Functions’ for details.

This looks really great ! I have written a pre-processor language for the templates in zena (a CMS) called zafu. It would be really easy to generate tenjin code instead of erb. By looking at the code, I don’t understand where the performance boost comes from. At the end, we have a ruby method, just like with erb, no ? Could explain why tenjin is faster ? Is it during compilation ? Or during execution (which means a compilation that generates faster ruby code) ? Thanks for your answer. Gaspard 2008/2/9, Michael N.

Cool! So I guess auto caching for Ruby was already implemented since the beginning… Regards, Michael
