# Documentation

data Range Source #

Character ranges. The first character in the file has position 1. Note that the `to` position is considered to be outside of the range.

Invariant: ``from` `<=` `to``.

rangesInvariant :: Ranges -> Bool Source #

The `Ranges` invariant.

overlapping :: Range -> Range -> Bool Source #

`True` iff the ranges overlap.

The ranges are assumed to be well-formed.

empty :: Range -> Bool Source #

`True` iff the range is empty.

rangeToPositions :: Range -> [Int] Source #

Converts a range to a list of positions.

rangesToPositions :: Ranges -> [Int] Source #

Converts several ranges to a list of positions.

rToR :: Range -> Ranges Source #

Converts a `Range'` to a `Ranges`.

rangeToEndPoints :: Range -> Maybe (Int, Int) Source #

minus :: Ranges -> Ranges -> Ranges Source #

`minus xs ys` computes the difference between `xs` and `ys`: the result contains those positions which are present in `xs` but not in `ys`.

Linear in the lengths of the input ranges.
