Yeoman生成器
我正在写一个生成器,用户将被提示一个参数,我们称之为option
。根据其答案,我想更改其中一个输出文件:
some class.Java
public class SomeClass{
//if option=x I don't want to include this attribute:
private String field1;
//if option=x I want to generate an attribute with the value of the promted attribute
private String ${info};
我如何进行上述评论中描述的操作?
回答如下:index.js
在prompting()
方法中,您将声明所有提示和包含名称的提示类型。然后在writing()
,你将把那些传递给模板,这里是MyClass.java
module.exports = class extends Generator {
prompting() {
// Have Yeoman greet the user.
this.log(yosay(
'Welcome to the remarkable ' + chalk.red('generator-react-starter-kit-relay-container') + ' generator!'
));
const prompts = [{
type: 'input',
name: 'info',
message: 'INFO IN YOUR CLASS'
}, {
type: 'confirm',
name: 'x',
message: 'YOUR OPTION X'
}];
return this.prompt(prompts).then(props => {
this.props = props;
});
}
writing() {
this.fs.copyTpl(
this.templatePath('MyClass.js'),
this.destinationPath(<YOUR DESTINATION PATH>),
{
info: this.props.info,
x: this.props.x
}
);
}
};
模板/ MyClass.java
public class MyClass{
<% if (x) { %>
private String <%= info %>;
<% } else { %>
private String field1;
<% } %>
}
