Example

Sample Mustache:

Hello {{name}} You have just won {{& value}} dollars! {{#in_ca}} Well, {{{taxed_value}}} dollars, after taxes. {{/in_ca}} {{#addresses}} Has address in: {{city}} {{/addresses}} {{^addresses}} Has NO addresses {{/addresses}}

The template features value access: {{name}}, conditionals: {{#in_ca}}, as well as repetitions: {{#addresses}}.

Sample code to parse and evaluate the template:

let sampleDict : [ String : Any ] = [ "name" : "Chris", "value" : 10000, "taxed_value" : Int(10000 - (10000 * 0.4)), "in_ca" : true, "addresses" : [ [ "city" : "Cupertino" ] ] ]

var parser = MustacheParser() let tree = parser.parse(string: template) let result = tree.render(object: sampleDict)

You get the idea.

Swift 5 Dynamic Callable

In Swift 5 you can expose Mustache templates as regular Swift functions.

To declare a Mustache backed function:

let generateHTMLForWinner = Mustache(
    """
    {% raw %}Hello {{name}}
    You have just won {{& value}} dollars!
    {{#in_ca}}
        Well, {{{taxed_value}}} dollars, after taxes.
    {{/in_ca}}
    {{#addresses}}
        Has address in: {{city}}
    {{/addresses}}
    {{^addresses}}
        Has NO addresses
    {{/addresses}}{% endraw %}
    """
)

To call the function:

let winners = [
    generateHTMLForWinner(
        name: "Chris", value: 10000,
        taxed_value: 6000, in_ca: true,
        addresses: [[ "city": "Cupertino" ]]
    ),
    generateHTMLForWinner(
        name: "Michael", value: 6000,
        taxed_value: 6000, in_ca: false,
        addresses: [[ "city": "Austin" ]]
    )
]
