What is libghc-regex-tdfa-dev
libghc-regex-tdfa-dev is:
A pure Haskell alternative to GHC’s Text.Regex module (with some enhancements). The Text.Regex module marshalls the data back and forth to c-arrays to call libc and this is far too slow (and strict).
This module parses regular expression Strings using a Parsec parser and creates an internal data structure (Text.Regex.Lazy.Pattern). This is then transformed a DFA table for matching against the input String or FastPackedString. The input string is consumed lazily, so it may be an arbitrarily long or infinite source.
This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
