Placeholder

A Placeholder Templating Engine without the complexity

You're probably familiar with how printf!(), format!(), and friends use {<named>} placeholders. This module uses that same style within its templates to give you that same feel but for use within a complete text templating engine.

Example 1

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

fn main() { let template = String::from("

{greet} {name}

Do you like {food}?

");

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("

Hello Homer

Do you like Donuts?

")));

} ```

Example 2 (missing placeholder values)

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

fn main() { let template = String::from("

{greet} {name}

");

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

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