nunjucks

It's also missing Nunjucks, which works in browser and server, can precompile templates (when done so is really fast), lets you do more logic in templates, has autoescaping, and a bunch of other stuff. Some big project like Mozilla's new Marketplace is using it. https://github.com/jlongster/nunjucks

Take this: env = jinja2.Environment() ast = env.parse(...) vars = jinja2.meta.find_undeclared_variables(ast) Now you've got a list of every part of the data model referenced by this template. Unfortunately this doesn't give you byte ranges for each reference, but that could be changed. Angular propagates changes to your data model to only the parts of the DOM that depend on it, which is cool. Imagine if you could do the same against a nunjucks template. Given the above kind of dependency analysis, I don't see why not. Maybe rendering snippets of a jinja template at runtime is problematic? Aside: yikes on the string-based codegen here...I bet you wish you were still writing scheme ;) https://github.com/jlongster/nunjucks/blob/master/src/compil...

I have a hard time adopting frameworks because of the all-or-nothing aspect of them. If you use Angular, you have to use their templating language, right? I know that they do a lot of powerful things with it, but honestly it's difficult for me to throw away all of my current tools. It's just too much of a jump. There's so much I love about libraries like angular and ember, but I'd love it if someone was working on a way to allow additional templating languages. I don't know how it would work, but you could possible compile other templates down to angular templates. I've been thinking of a way to convert simple templates in angular's style, so that you can do all the cool auto-updating features. If there was a standard for this, templates like mustache, etc could compile a subset down to it. Disclaimer: I'm the creator of nunjucks https://
