This package contains libraries dealing with regular expressions:
RegExpSem: This library specifies the semantics of regular expressions and regular expression matching in a high-level manner via non-deterministic operations. It might be useful as an oracle to test more efficient regular expression matchers.
RegExp: This library defines a structure of regular expressions and some operations like match and capture for regular expression. Since the implementation is high-level but quite inefficient, it can only be used for smaller string matching.
RegExpEff: This library defines a structure of regular expressions and some efficient operations like
capturefor larger regular expression matching.
Note that the libraries
RegExpEff are useful in combination with the Curry preprocessor to translate integrated code in the form of POSIX extended regular expressions into Curry programs. See example program
TestRegExpCode.curry in directory
test or the examples in the package of the Curry preprocessor.
