        if(token==="customplugin"){
            yield (new Date(Date.now())).getFullYear()
        }    
    }

}


const main = async function (){

    const templateFileToRead = "./template.txt"
    const dictionaryFileToRead = "./dictionary.json"

    // Example 1 using no plugins and files
    const foo = await interpolateFromFiles({templateFileToRead,dictionaryFileToRead,
       plugins:[
        ]
    });
    for await (let item of foo()){
        console.log(item)
    }
    
    // Example 2 using getSplit plugin and customPlugin
