The regex-* packages are polymorphic in the string type they accept, so it should be possible to use them with bytestrings. E.g. * http://hackage.haskell.org/package/regex-pcre * http://hackage.haskell.org/package/regex-posix * http://hackage.haskell.org/package/regex-tdfa (you can choose which regex automata you like) kathleen.fisher:
I want a version of the Text.Regex library where the input is a character-based ByteString instead of a String. I haven't found one on hackage, although I'm not convinced I've looked exhaustively. (Every time I try to explore the regular expression libraries on Hackage, I end up in a maze of documentation, never sure precisely where I am or where I should be going.) It would be really helpful if there were a few English paragraphs somewhere explaining the high-level model provided by the various modules!
I ended up taking a version of Text.Regex and making changes to produce a library that works for lazy character ByteStrings. Is that a reasonable thing to do? I'm going to make my software public soon, so I'll either need to release this modified library or swap my version out for a more standard one.
Any suggestions on the best way to proceed?
