ghc-filepattern

A library for matching files using patterns such as '"src/**/*.png"' for all '.png' files recursively under the 'src' directory. Features: * All matching is /O(n)/. Most functions precompute some information given only one argument. * See "System.FilePattern" and '?==' simple matching and semantics. * Use 'match' and 'substitute' to extract suitable strings from the '*' and '**' matches, and substitute them back into other patterns. * Use 'step' and 'matchMany' to perform bulk matching of many patterns against many paths simultaneously. * Use "System.FilePattern.Directory" to perform optimised directory traverals using patterns. Originally taken from the <https://hackage.haskell.org/package/shake Shake library>.
