How does Dart rename PsiElement?

已回答

Hello, I want to implement an automatic repair function

 

class DartPublicFunctionFix : LocalInspectionTool() {

override fun buildVisitor(holder: ProblemsHolder, isOnTheFly: Boolean): PsiElementVisitor {
return DartPublicFunctionApiFixVisitor(holder = holder)
}


}

class DartPublicFunctionApiFixVisitor(val holder: ProblemsHolder) : PsiElementVisitor() {

override fun visitElement(element: PsiElement) {
//如果节点是一个类
if(element is DartClassDefinitionImpl ) {

//判断是不是继承自StatefulWidget类
val superClassList = element.childrenOfType<DartSuperclassImpl>()
if(superClassList.isNotEmpty()){
val superClassName = superClassList.first().childrenOfType<DartTypeImpl>().first().text
if(checkSuperClassNames.contains(superClassName)){
///包含需要待检测的类
val methods = element.childrenOfType<DartClassBodyImpl>().first().childrenOfType<DartClassMembersImpl>()
.first().childrenOfType<DartMethodDeclarationImpl>()
val names = methods.filter { it.childrenOfType<DartComponentNameImpl>().first().text == "createState" }
if(names.isNotEmpty()){
val dmdElement = names.first() //DartMethodDeclarationImpl节点
val name = dmdElement.childrenOfType<DartComponentNameImpl>().first().text
if(name.equals("createState")){
val returnTypes = dmdElement.childrenOfType<DartReturnTypeImpl>()
if(returnTypes.isNotEmpty()){
val returnTypeEle = returnTypes.first()
if(returnTypeEle.text.indexOf("_") == 0){
holder.registerProblem(returnTypes.first(),"dart建议将返回类型修改为公有变量. QQ自学群:667186542欢迎加入",
ProblemHighlightType.WARNING,PublicApiRenameFix(returnTypeEle,returnTypeEle.text))
}

}
}
}
}
}
}
super.visitElement(element)
}
}

 

class PublicApiRenameFix(val element: PsiElement,var className: String): LocalQuickFixOnPsiElement(element) {
private val renameText = className.removePrefix("_")

override fun getFamilyName(): String {
return "梁典典: 将它重命名为$renameText"
}
override fun getText(): String {
return familyName
}

override fun invoke(project: Project, file: PsiFile, startElement: PsiElement, endElement: PsiElement) {

val factory = PsiElementFactory.getInstance(project)
val newNamePsi = factory.createDummyHolder(renameText, IElementType(
"RETURN_TYPE",DartLanguage.INSTANCE
),null)


startElement.replace(newNamePsi)
}

}

 

But an error occurred when testing,How can I solve this problem?

Hi,

Your element type is not recognized by the Dart parser. Why do you create a new element type:

IElementType("RETURN_TYPE", DartLanguage.INSTANCE)


instead of using the existing DartTokenTypes.RETURN_TYPE?
