Ace编辑器HighlightRules，规则无休止地嵌套

Question

使用Ace Editor HighlightRules ，我想知道如何定义可以无限嵌套的规则。

const rules = {
  start: [
    { ...segmentationName, next: 'segmentation' },
  ],
  segment: [
    { ...enclosingOperatorStart, next: 'enclosingOperator' },
    segmentCommand,
    { ...emptyLine, next: 'segmentation' },
  ],
  enclosingOperator: [
    segmentCommand,
    { ...enclosingOperatorEnd, next: 'segment' },
  ],
};

在上面的规则中，我希望enclosingOperator无限地嵌套，以便能够允许以下示例。

@Frankenstein/tf1-et-vous/PhotosList  //segmentationName
host www.tf1.fr                       //segmentCommand
path /tf1-et-vous/*
and (                                 //enclosingOperatorStart
path */photos/*                       //segmentCommand
path */photos-* 
or (                                  //enclosingOperatorStart
path */photos/*
path */photos-*
path */photo/*
)                                     //enclosingOperatorEnd
path */photo/*
)                                     //enclosingOperatorEnd

我可以在enclosingOperatorStart步骤中添加enclosingOperator节点，但在enclosingOperatorEnd中，下一个需要segment，如果最高级别否则堆叠enclosingOperator

const rules = {
  start: [
    { ...segmentationName, next: 'segmentation' },
  ],
  segment: [
    { ...enclosingOperatorStart, next: 'enclosingOperator' },
    segmentCommand,
    { ...emptyLine, next: 'segmentation' },
  ],
  enclosingOperator: [
    { ...enclosingOperatorStart, next: 'enclosingOperator' },
    segmentCommand,
    { ...enclosingOperatorEnd, next: '?????????' },
  ],
};

使用push: <statename>向堆栈添加状态，并使用next: pop将其删除。请注意，要使用此功能，您需要在构造函数中调用this.normalizeRules()。
