Crate varj

A string interpolation utility to replace Mustache like placeholders with stored variables.

• Works as an extremely lightweight template library
• Does not require template compilation
• Simply replaces {{ key }} with value
• Whitespace surrounding the key is ignored: {{key}} and {{ key }} are equal.

Interact with this utility via VarjMap

Examples

Basic usage:

let mut map = varj::VarjMap::new();
map.insert("key", "value");

assert_eq!(
    "value",
    map.render("{{ key }}")?
);

With a json string:

let mut variables = varj::VarjMap::new();
variables.insert("name", "Christopher");
variables.insert("age", "30");

let json = r#"{
    "name" = "{{ name }}",
    "age" = {{ age }}
}"#;

let expected = r#"{
    "name" = "Christopher",
    "age" = 30
}"#;

let actual = variables.render(json)?;

assert_eq!(expected, actual);
