const acorn = require("acorn");
const walk = require("acorn-walk");

walk.simple(acorn.parse("import i18n from \"i18n\"; const str = i18n`foo ${bar} haha`", {sourceType: "module"}), {
	// https://github.com/estree/estree/blob/master/es2015.md#template-literals
    TaggedTemplateExpression(node) {
    	console.log("TaggedTemplateExpression:")
        console.log(JSON.stringify(node, undefined, 2));
    },
    ImportDeclaration(node) {
    	console.log("ImportDeclaration:")
        console.log(JSON.stringify(node, undefined, 2));
    }
});

could also use a local variable for the tag instead of a global imported variable

e.g. support

const str = this.i18n`foo ${bar} haha`;
