Show HN: Blueprint: Fast, Nunjucks-like templating engine for Java 8 and beyond

I love the simplicity, expressibility and extendibility of Nunjucks.

But I was not able to find something with similar for Java, especially with the same syntax.

So, built one. And it's pretty fast too.

We never hear about Java on this forum. That makes a post like this peculiarly interesting

Good to know.

Normally I'd use Spring Boot and get the batteries-included experience if I ever were to make web with Java.

But I could totally imagine needing a pure, well-made, zero-deps template engine for custom jobs.

I certainly have similar libraries in my bookmarks for other languages, like Haskell [1] and Rust [2].

Isn't Pebble Templates similar to this?

Looks interesting. For me I settled on JTE as the go-to template engine for Java. For anyone curious: https://jte.gg @freakynit - have you seen this one before? how's it compares with Blueprint?

Syntax looks very much like Liquid. I feel like that syntax is becoming a standard.

afaik django or jinja invented this syntax? then we saw handlebars, which is where liquid got its influence.
