Hi guys,
I have tried to understand how ERB works and I have designed my own
template engine : {% statement %} and {{ expression }}.
I want to share the code with you :
https://gist.github.com/astraction/6351299
Only 33 lines of code (Ruby is so powerful !) and it should be much
faster than ERB (but I haven't done any benchmarks).
It's mainly for learning purpose. Of course, there is much room for
improvement (caching the compiled code, helpers methods, feel free to
help me).
Sébastien

Your regexes are flawed because they are too greedy:
irb(main):001:0> '{{a}}{{b}}'.scan(/{%(.+)%}|{{(.+)}}|([^{}]+)/)
=> [[nil, "a}}{{b", nil]]
You should at least use reluctant quantifier:
irb(main):002:0> '{{a}}{{b}}'.scan(/{%(.+?)%}|{{(.+?)}}|([^{}]+?)/)
=> [[nil, "a", nil], [nil, "b", nil]]
Cheers

You have to know that exists others alternatives.
I prefer haml, is very powerful and fast.

Haml is anything but fast. It blows your method caches any time you render
a template:
