Double for-loop can not be used?

[hhatto]

main.rs

extern crate tera;
use std::env;
use std::path::Path;
use tera::{Tera, Context};

fn main() {
    let root_path = env::current_dir().unwrap();
    let template_dir = root_path.join(Path::new("templates/*"));
    let template_engine = Tera::new(template_dir.to_str().unwrap());
    let mut context = Context::new();

    let vectors = vec![vec![0, 3, 6], vec![1, 4, 7]];
    context.add("vectors", &vectors);
    println!("{}", template_engine.render("double-loop.tera", context).unwrap());
}

templates/double-loop.tera:

{% for vector in vectors %}
  {% for j in vector %}
    j={{ j }}
  {% endfor %}
{% endfor %}

output:

j=0
  j=3
  j=6
j=0
  j=3
  j=6

P.S.

tera is good library 😄
I have been using in the build script.

Thanks.

Thanks for the bug report! I'll have a look later today or this weekend

It's fixed in master if you want to try, I'll try to get a release out in a couple of days once we have more filters (#46)

[hhatto]

Thanks.
I was able to confirm that it is fixed in the master.

@Keats
I found another problem.
It does not work correctly, when there is empty vector in for-loop.

patch this: hhatto@8b4684c

[Keats]

Thanks, I pushed the fix to master!

Thank you very much 😃
