getOffsetsForEmptyRangeInsert
▸ getOffsetsForEmptyRangeInsert(changeEventInfo, rangeInfo): RangeOffsets
Gets updated offsets for the range rangeInfo after the change described by
changeEventInfo. This function will only be called if the following hold:
- the change is an insert event, ie a change event for which the original range is empty, and
- the range to be updated is empty, and
- the insertion position is equal to the position of the empty range to be updated.
The approach taken here is to first look at the isReplace field of the
change to determine whether it should shift empty ranges to the right. If
it shifts them to the right, we then look at its left / start expansion
behaviour. If does not shift empty ranges, then we look at its right / end
expansion behaviour.
If the given expansion behaviour is "open", we expand to contain the new text, if "closed" we do not expand, and if "regex", we expand to contain as much of the inserted text as matches the given regex, anchored at the opposite end.
