Template inheritance. See http://docs.djangoproject.com/en/dev/topics/templates/#id1

  `Template inheritance¶
  The most powerful -- and thus the most complex -- part of 
  Django's template engine is template inheritance. Template 
  inheritance allows you to build a base "skeleton" template 
  that contains all the common elements of your site and 
  defines blocks that child templates can override.`

Having made it in lua myself, I can tell you it is indeed quite complex. ;)

The lua template only has "include" (i.e. copying another template into this template), but not "extends", (i.e. use another template as a skeleton and this template only provides details on how to fill it).

this is awesome, feel like writing it for ruby too?

Check out DRYML from the Hobo project (hobocentral.net). You build taglibs that can be used and overridden however you like.

I don't know ruby... but RoR is an established platform, I would think it would have something similar?

Not with the same notion of inheritance that django templates have (with multiple blocks that can be overridden in child classes). There is one project someone attempted but never finished.

Well, I only did what I needed, but since Lua's included code blocks are also functional, wouldn't it be easier to just allow passing arguments? It'd also make a lot more sense. I find Django/Jinja inheritance concepts really confusing.

I'll take a look at the code and see what I can come up with.

If you wanted, say, your about page to have an extra image next to the logo (as an exception to all the other pages), then you'd have to rewrite another header file to include, whereas if you used template inheritance you could just override that logo part without having another almost identical header file.

It may be confusing if you're new to it... but so are OOP, Lambda calculus, and others. ;)

EDIT: The code isn't that clean... Apologies in advance.
