lodash之模板设置

templateSettings

今天在看lodash的typescript定义文件时，发现有这么一处定义：

declare namespace _ {
     interface LoDashStatic {

     }

     /**  * By default, the template delimiters used by Lo-Dash are similar to those in embedded Ruby  *默认像ruby里的嵌入式  * (ERB). Change the following template settings to use alternative delimiters.  **/
  * By default, the template delimiters used by Lo-Dash are similar to those in embedded Ruby
  *默认像ruby里的嵌入式
  * (ERB). Change the following template settings to use alternative delimiters.
  **/
  interface TemplateSettings {
      /**      * The "escape" delimiter.      **/
      * The "escape" delimiter.
      **/
      escape?: RegExp;

      /**      * The "evaluate" delimiter.      **/
      * The "evaluate" delimiter.
      **/
      evaluate?: RegExp;

      /**      * An object to import into the template as local variables.      **/
      * An object to import into the template as local variables.
      **/
      imports?: Dictionary<any>;

      /**      * The "interpolate" delimiter.      **/
      * The "interpolate" delimiter.
      **/
      interpolate?: RegExp;

      /**      * Used to reference the data object in the template text.      **/
      * Used to reference the data object in the template text.
      **/
      variable?: string;
  }
}

我们看到lodash的官网上有这么一处举例：

`js // using custom template delimiters(分隔符) _.templateSettings.interpolate = /undefined/g; var compiled = _.template('hello !'); compiled({ 'user': 'mustache' }); // => 'hello mustache!'
