Any way to delete a file before create

Answered

Created May 03, 2022 02:01

I am trying to create a file by psiFileFactory:

val project = e.getData(PlatformDataKeys.PROJECT)
var psiFileFactory = PsiFileFactory.getInstance(project)
val createFileFromText = psiFileFactory.createFileFromText("soc.md", "fadsfdsaf")
var directory = modFile.containingDirectory
directory.add(createFileFromText)

But it could generate error if there is the same file. So is there any way to delete the same name file before create?

Assuming `directory` is a `com.intellij.psi.PsiDirectory`, `com.intellij.psi.PsiDirectory#checkCreateFile`

What I want is to overwrite the same file if the file exists. But `checkCreateFile` is utilized to check if it's possible to crate a file.

PsiDirectory#findFile(), if found, PsiFile#delete, then proceed with adding new file like before

If try to delete file like this, it seems the delete operation was executed. But it would generate the below error.

val createFileFromText = psiFileFactory.createFileFromText("sca.md", result)
var directory = modFile.containingDirectory
directory.findFile("sca.md")?.delete()
directory.add(createFileFromText)
