FileSystem Create empty file - touch like

[vanniktech]

I'm looking for something along the lines of a touch. My current implementation is this:

  override fun touch(child: String) {
    val path = root / child
    path.parent?.let { fileSystem.createDirectories(it) }

    fileSystem.sink(path).buffer().use {
      it.emit()
    }
  }

This does create an empty file. Is this the 'right' way? Also, should there be a first party function for creating an empty file?

My use case creating an empty file.jpeg so that Androids Intent for the camera can write the final pixels into that file.

What you've got looks great. You can omit the emit() call, which will just no-op as-is.

I am reluctant to add an extra function for this 'cause I don't want developers to accidentally create an empty file before they start writing. Just writing is sufficient.

Alright cool, thanks!
