Crate placeholder

Placeholder - A Placeholder Templating Engine without the complexity

Example 1

use placeholder::render;
use std::collections::HashMap;

fn main() {
  let template = String::from("<h1>{greet} {name}</h1><p>Do you like {food}?</p>");

  let mut values = HashMap::new();
  values.insert(String::from("greet"), String::from("Hello"));
  values.insert(String::from("name"), String::from("Homer"));
  values.insert(String::from("food"), String::from("Donuts"));

  assert!(render(&template, &values)
    == Ok(String::from("<h1>Hello Homer</h1><p>Do you like Donuts?</p>")));

}

Example 2 (missing placeholder values)

use placeholder::render;
use std::collections::HashMap;

fn main() {
  let template = String::from("<h1>{greet} {name}</h1>");

  let mut values = HashMap::new();
  values.insert(String::from("greet"), String::from("Hello"));

  assert!(render(&template, &values)
    == Err(String::from("name")));
}
