如何在JetBrains MPS中为JSON的Key定义带双引号的编辑器？

现有概念定义 #

concept ObjectNode extends JsonNode
                   implements <none>

  instance can be root: true 
  alias: <no alias> 
  short description: <no short description> 

  children: 
  keyValues : KeyValue[0..n] 

concept KeyValue extends BaseConcept
                 implements <none>

  instance can be root: false 
  alias: <no alias> 
  short description: <no short description> 

  children: 
    key : Key[1]        
    value : JsonNode[1]                          

concept Key extends BaseConcept
implements <none>

instance can be root: false
alias: <no alias>
short description: <no short description>

properties:
name : string

编辑器配置方案 #

将Key概念的默认编辑器修改为以下配置，即可实现带双引号的显示效果：

<default> editor for concept Key
  node cell layout:             
     composite {
       static text: "\""
       property: name
       static text: "\""
     }        
                                
  inspected cell layout:        
    composite {
       static text: "\""
       property: name
       static text: "\""
     }         
                                

配置说明 #

• 采用composite单元格模型，把静态文本和属性元素组合成整体
• 静态文本"\""用于显示双引号，反斜杠是转义符，确保MPS能正确识别双引号字符
• property: name关联Key概念的name属性，展示实际的键名内容
