-- | syntax highlighting library
--
-- Skylighting is a syntax highlighting library. It derives its
-- tokenizers from XML syntax definitions used by KDE's
-- KSyntaxHighlighting framework, so any syntax supported by that
-- framework can be added. An optional command-line program is provided.
-- Skylighting is intended to be the successor to highlighting-kate. This
-- package provides the core highlighting functionality under a
-- permissive license. It also bundles XML parser definitions licensed
-- under the GPL.
@package skylighting-core

compileRegex :: Bool -> ByteString -> Either String Regex
-- | Match a Regex against a (presumed UTF-8 encoded) ByteString, returning
-- the matched text and a map of (offset, size) pairs for captures. Note
-- that all matches are from the beginning of the string (a ^
-- anchor is implicit). Note also that to avoid pathological performance
-- in certain cases, the matcher is limited to considering 2000 possible
-- matches at a time; when that threshold is reached, it discards smaller
-- matches. Hence certain regexes may incorrectly fail to match: e.g.
-- a*a{3000}$ on a string of 3000 as.
