addOldDelta Source #

Arguments

:: PositionDelta	delta from version k - 1 to version k
-> PositionMapping	The input mapping is from version k to version n
-> PositionMapping	The output mapping is from version k - 1 to version n

addOldDelta Add a old delta onto a Mapping k n to make a Mapping (k - 1) n

idDelta :: PositionDelta Source #

composeDelta :: PositionDelta -> PositionDelta -> PositionDelta Source #

Compose two position mappings. Composes in the same way as function composition (ie the second argument is applied to the position first).

mkDelta :: [TextDocumentContentChangeEvent] -> PositionDelta Source #

Convert a set of changes into a delta from k to k + 1

toCurrentRange :: PositionMapping -> Range -> Maybe Range Source #

fromCurrentRange :: PositionMapping -> Range -> Maybe Range Source #

applyChange :: PositionDelta -> TextDocumentContentChangeEvent -> PositionDelta Source #

zeroMapping :: PositionMapping Source #

deltaFromDiff :: Text -> Text -> PositionDelta Source #

toCurrent :: Range -> Text -> Position -> PositionResult Position Source #

fromCurrent :: Range -> Text -> Position -> PositionResult Position Source #
