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:

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

let expected = "value"; let actual = vars.parse("{{ key }}")?;

assert_eq!(expected, actual); ```

With a json string:

```rust 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.parse(json)?;

assert_eq!(expected, actual); ```
