It has the\n * signature: `(part: Part) => void`.\n *\n * A directive _factory_ is a function that takes arguments for data and\n * configuration and returns a directive. Users of directive usually refer to\n * the directive factory as the directive. For example, \"The repeat directive\".\n *\n * Usually a template author will invoke a directive factory in their template\n * with relevant arguments, which will then return a directive function.\n *\n * Here's an example of using the `repeat()` directive factory that takes an\n * array and a function to render an item:\n *\n * ```js\n * html`
    <${repeat(items, (item) => html`
  • ${item}
    • `)}
`\n * ```\n *\n * When `repeat` is invoked, it returns a directive function that closes over\n * `items` and the template function. When the outer template is rendered, the\n * return directive function is called with the Part for the expression.\n * `repeat` then performs it's custom logic to render multiple items.\n *\n * @param f The directive factory function. Must be a function that returns a\n * function of the signature `(part: Part) => void`. The returned function will\n * be called with the part object.\n *\n * @example\n *\n * import {directive, html} from 'lit-html';\n *\n * const immutable = directive((v) => (part) => {\n * if (part.value !== v) {\n * part.setValue(v)\n * }\n * });\n */\nexport const directive = (f) => ((...args) => {\n const d = f(...args);\n directives.set(d, true);\n return d;\n});\nexport const isDirective = (o) => {\n return typeof o === 'function' && directives.has(o);\n};\n//# sourceMappingURL=directive.js.map","/**\n * @license\n * Copyright (c) 2018 The Polymer Project Authors.
