Yeoman Generator：CLI +文件而不是提示 [英] Yeoman Generator: CLI+File Instead of Prompt

问题描述

我一直在使用一些Yeoman Generators来提示我输入用户信息。不过，我希望将输入内容放入JSON文件中。我可以看到 yo-rc.json 之后会生成，但是我想使用它（或类似的文件）作为Yeoman的输入。

使用 JHipster 的示例：

当前行为

  $ yo jhipster 
 
欢迎使用JHipster Generator v2 .16.1 
？ （1/15）您的应用程序的基本名称是什么？ （jhipster）helpme 
吗？ （2/15）您的默认Java软件包名称是什么？ com.mycompany.helpme 
 ... 
 
＃Yeoman Generator通过用户输入创建项目
  

期望的行为

  $ cat my-custom.json 
 {
 generator-jhipster：{
 baseName： helpme，
 packageName： com.mycompany.helpme，
 ... 
 
 $ yo jhipster --file my-custom.json 
 ... 
 
＃Yeoman Generator通过输入文件
   
 
 
听起来我应该能够利用 Yeoman Storage API ，但我个人还没有成功完成这条路线，也找不到任何类似的例子。
 
 
 
 [Edit]后续步骤
 
 
 
接下来，我想生成没有提示的实体，每个实体具有复杂的关系（ https： //jhipster.github.io/managing_relationships.html ）。我发现这是一个两步过程：
 
 
创建 ./。jhipster / MyEntity.json  
 
 
  yo jhipster：entity MyEntity.json  
 
 
利润
 
 
 
 
解决方案
 Jhipster已经做到了，可以看到我对您的问题的评论。 
下面是jhipster读取.yo-rc.json的地方，如果您确实想要其他名称，也只需使用文件api读取该文件，但我建议您保留json命名为.yo-rc.json以实现兼容性
 
 
 
 app / index.js中的代码
  this.baseName = this.config.get（'baseName'）; 
 this.packageName = this.config.get（’packageName’）; 
 this.authenticationType = this.config.get（‘authenticationType’）; 
 this.clusteredHttpSession = this.config.get（‘clusteredHttpSession’）; 
 this.searchEngine = this.config.get（‘searchEngine’）; 
 this.websocket = this.config.get（‘websocket’）; 
 this.databaseType = this.config.get（‘databaseType’）; 
 if（this.databaseType =='mongodb'）{
 this.devDatabaseType ='mongodb'; 
 this.prodDatabaseType ='mongodb'; 
 this.hibernateCache =否； 
}否则，如果（this.databaseType ==‘cassandra’）{
 this.devDatabaseType =‘cassandra’; 
 this.prodDatabaseType ='cassandra'; 
 this.hibernateCache =否； 
} else {// sql 
 this.devDatabaseType = this.config.get（’devDatabaseType’）; 
 this.prodDatabaseType = this.config.get（‘prodDatabaseType’）; 
 this.hibernateCache = this.config.get（’hibernateCache’）; 
} 
 this.useCompass = this.config.get（‘useCompass’）; 
 this.javaVersion = this.config.get（’javaVersion’）; 
 this.buildTool = this.config.get（’buildTool’）; 
 this.frontendBuilder = this.config.get（’frontendBuilder’）; 
 this.rememberMeKey = this.config.get（’rememberMeKey’）; 
 this.enableTranslation = this.config.get（‘enableTranslation’）; //默认情况下启用此功能，以避免与现有应用程序发生冲突
 this.packagejs = packagejs; 
  
 
I've been using a few Yeoman Generators that prompt me for user input.  I'd prefer to put my inputs in a JSON file though.  I can see that yo-rc.json gets generated afterwards, but I'd like to use that (or a file like it) as an input to Yeoman.

Example using JHipster:

Current Behavior

$ yo jhipster

Welcome to the JHipster Generator v2.16.1
? (1/15) What is the base name of your application? (jhipster) helpme
? (2/15) What is your default Java package name? com.mycompany.helpme
...

# Yeoman Generator creates project via user inputs


Desired Behavior

$ cat my-custom.json
{
  "generator-jhipster": {
    "baseName": "helpme",
    "packageName": "com.mycompany.helpme",
    ...

$ yo jhipster --file my-custom.json
...

# Yeoman Generator creates project via input file
It sounds like I should be able to leverage the Yeoman Storage API, but I haven't personally succeeded with that route, nor can I find any similar examples.

[Edit] Next Steps

Next I wanted to generate entities, unprompted, with complex relationships per (https://jhipster.github.io/managing_relationships.html).  I found this to be a 2-step process:

Create ./.jhipster/MyEntity.json 
yo jhipster:entity MyEntity.json
Profit

解决方案
Jhipster already does that see my comment on your question.
Below is where jhipster reads the .yo-rc.json, if you really want any other name it can be done as well, you just need to read that file using file api, but I would suggest you keep your json named .yo-rc.json for compatibility

Code from app/index.js 
this.baseName = this.config.get('baseName');
   this.packageName = this.config.get('packageName');
   this.authenticationType =  this.config.get('authenticationType');
   this.clusteredHttpSession = this.config.get('clusteredHttpSession');
   this.searchEngine = this.config.get('searchEngine');
   this.websocket = this.config.get('websocket');
   this.databaseType = this.config.get('databaseType');
   if (this.databaseType == 'mongodb') {
       this.devDatabaseType = 'mongodb';
       this.prodDatabaseType = 'mongodb';
       this.hibernateCache = 'no';
   } else if (this.databaseType == 'cassandra') {
       this.devDatabaseType = 'cassandra';
       this.prodDatabaseType = 'cassandra';
       this.hibernateCache = 'no';
   } else { // sql
       this.devDatabaseType = this.config.get('devDatabaseType');
       this.prodDatabaseType = this.config.get('prodDatabaseType');
       this.hibernateCache = this.config.get('hibernateCache');
}
   this.useCompass = this.config.get('useCompass');
   this.javaVersion = this.config.get('javaVersion');
   this.buildTool = this.config.get('buildTool');
   this.frontendBuilder =   this.config.get('frontendBuilder');
   this.rememberMeKey = this.config.get('rememberMeKey');
   this.enableTranslation = this.config.get('enableTranslation'); // this is enabled by default to avoid conflicts for existing applications
   this.packagejs = packagejs;
