I’m getting confused with the seemingly overlapping concepts of head/tail, and start/end for markers. Some questions, with apologies if I have been to stupid to find the answers:
-
are markers’ heads the same as their start, and tails the same as ends, unless the marker is reversed? It appears so, but a confirmation would be helpful.
-
I would assume that, for a non-reversed marker, head comes before tail. But:
-
Create a display marker with range (0,0) to (2,0):
displayMarkerLayer = this.editor.addMarkerLayer() displayMarker = displayMarkerLayer.markBufferRange([[0,0],[2,0]])
-
Check for the marker’s range. It is indeed lines 0 to 2:
displayMarker.getBufferRange() -> Range {[..] end: Point column: 0 row: 2 start: Point column: 0 row: 0
-
-
But: The head is actually at the end position, and tail is the start:
displayMarker.getTailBufferPosition() -> Point {row: 0, column: 0} displayMarker.getHeadBufferPosition() -> Point {row: 2, column: 0}
-
The marker is not reversed
displayMarker.isReversed() -> false
- Is displayMarker(Layer) a replacement for marker(Layer), or are these different APIs aimed at different layers within the architecture?
