javascript - Grunt-scaffold after() 函数访问提示答案

Question

The docs对于 NPM 包 grunt-scaffold 缺乏关于其 after() 属性/函数的任何信息。我​​有一个 grunt 文件，它为新脚本创建一个新目录，并且将样板文件从指定的模板文件夹复制到其中。我们的愿望是完成 gruntscaffold:new_script 命令并让它注销新生成的文件夹的位置。

Gruntfile.js

  module.exports = function(grunt) {
  grunt.initConfig({
  scaffold: {
    new_script: {
        options: {
            questions: [{
                name: 'script_name',
                type: 'input',
                message: 'Script name, catterpillar_case?(e.g. \'new_script\'):'
            }],
            template: {
                "scripts/etl_template/": "scripts/{{script_name}}/",
            },
            after: function(){

                console.log("New script generated in new folder scripts/{{script_name}}")
            }
        }
      }
    }
  });
  grunt.loadNpmTasks('grunt-scaffold');
  grunt.registerTask('default', ['scaffold']);
};

但是，输出是

-bash-4.1$ grunt scaffold:new_script
Running "scaffold:new_script" (scaffold) task
? Script name, catterpillar_case?(e.g. 'new_script'): test_grunt
New script generated in new folder scripts/{{script_name}}
Done.

这并没有像创建 scripts/test_grunt 文件夹时那样进行字符串替换!如您所见the documentation after() 功能几乎不存在，我想知道是否可以使用 javascript"system argume

Answer 1

文档中没有给出 after() 函数的示例，但如果您使用与 filter() 示例中相同的结果参数，您可以通过名称访问答案值。

Gruntfile.js

  module.exports = function(grunt) {
  grunt.initConfig({
  scaffold: {
    new_script: {
        options: {
            questions: [{
                name: 'script_name',
                type: 'input',
                message: 'Script name, catterpillar_case?(e.g. \'new_script\'):'
            }],
            template: {
                "scripts/etl_template/": "scripts/{{script_name}}/",
            },
            after: function(result){
                console.log("New script generated in new folder scripts/" + result.script_name)
            }
        }
      }
    }
  });
  grunt.loadNpmTasks('grunt-scaffold');
  grunt.registerTask('default', ['scaffold']);
};

输出

-bash-4.1$ grunt scaffold:new_script
Running "scaffold:new_script" (scaffold) task
? Script name, catterpillar_case?(e.g. 'new_script'): test_grunt
New script generated in new folder scripts/test_grunt
Done.
