Iterating with for and else

Looping through iterators is straightforward, and the loop filter adds helpful index information.

<ul>
  {%- for (loop, name) in &names | loop %}
    <li>
      {{- loop.index1 }} ({{ loop.index0 }}): {{ name }}
      {%- if loop.is_first %} (first){% endif %}
      {%- if loop.is_last %} (last){% endif %}
  {%- else %}
    <li><em>No names found</em>
  {%- endfor %}
</ul>{-}

extern crate oxiplate;

use oxiplate::prelude::*;

#[derive(Oxiplate)]
#[oxiplate = "for.html.oxip"]
struct YourStruct {
    names: Vec<&'static str>,
}

assert_eq!(
    YourStruct {
        names: vec!["Jasmine", "Malachi", "Imogen"],
    }.render()?,
    r#"<ul>
    <li>1 (0): Jasmine (first)
    <li>2 (1): Malachi
