Ignore comments within String constants

[nedtwigg]

This code is too simple.

selfie/selfie-lib/src/commonMain/kotlin/com/diffplug/selfie/guts/CommentTracker.kt

Lines 51 to 54 in 6c3d0ee

	// TODO: there is a bug here due to string constants, and non-C file comments
	val newComment =
	if (str.contains("//selfieonce") || str.contains("// selfieonce")) {
	WritableComment.ONCE

selfie/selfie-lib/src/commonMain/kotlin/com/diffplug/selfie/guts/SourceFile.kt

Lines 83 to 87 in 6c3d0ee

	fun removeSelfieOnceComments() {
	// TODO: there is a bug here due to string constants, and non-C file comments
	contentSlice =
	Slice(contentSlice.toString().replace("//selfieonce", "").replace("// selfieonce", ""))
	}

For example:

class Test {
  @Test public void example() {
    expectSelfie("underTest").toBe("""
This is a string constant
// selfieonce
The comment above is not really a comment.
We effectively have a "forbidden value" that can't be inside inline snapshots.
     """)
  }
}
