regex-applicative is aimed to be an efficient and easy to use parsing combinator library for Haskell based on regular expressions.
Perl programmers often use regular expressions for parsing, even if it is not an appropriate tool for the job, because Perl has so good support for regexps.
The opposite seems to be valid about Haskell programmers – they use parsing combinators (which recognize context-free or even context-sensitive grammars), even when the language is actually regular!
Hopefully, this library will improve the situation.
Install this library using
cabal update cabal install regex-applicative
The API reference is available from Hackage.
To get started, see some examples on the wiki.
Make a release to refresh the haddocks on hackage (see https://github.com/feuerbach/regex-applicative/issues/35).
