Lightning talk about the new Python-based template language called Spitfire. Given at the Plone Conference 2007 in Naples, Italy by Alexander Limi — http://limi.net

1. All Template Languages Suck Suck Suck

2. aka

3. Why another template language?

4. Because we can™

8. Yours truly

9. (markup obsessive)

10. Also, because

11. All Template Languages Suck Suck Suck

12. Why do they suck?

13. Let me count the ways…

14. Either they look like this

15. UGLY <p class=”<?php someClass() ?>”> <?php callSomeFunction() ?> </p>

16. Or they perform like this

18. We can do better

19. We want

20. NICE <p tal:content=”context/something”> Text goes here </p>

21. and

23. What are your current options?

25. Let’s do a simple benchmark

26. Standardized test bigtable.py http ://genshi.edgewall.org/wiki/GenshiPerformance · obviously synthetic · 10×1000 table render · measures pure throughput · measures pure throughput · measures pure throughput · measures pure throughput · measures pure throughput · measures pure throughput · measures pure throughput · measures pure throughput

27. Rendering times

30. 100% Python goodness

31. Current version: Compiler: ~2000 LoC Runtime: 150 LoC Runtime: 150 LoC Runtime: 150 LoC Runtime: 150 LoC

32. Compiles templates to bytecode

33. Pluggable syntax

34. Both XML and text modes
