    Dregex is a Scala/JVM library that implements a regular expression engine using deterministic finite automata (DFA).

    Dregex is a Scala/JVM library that implements a regular expression engine using deterministic finite automata (DFA). The range of features supported is an middle ground between Perl-style (slow) engines and DFA-based ones. Yet it retains the linear matching time offered by the latter.

  7. def diff(other: Regex): Regex

    Subtract other regular expression from this one.

    Subtract other regular expression from this one. The resulting expression will match the strings that are matched this expression and are not matched by the other, and only those. Differences take O(n*m) time, where n and m are the number of states of the DFA of the operands.

    Return whether this regular expression is equivalent to other.

    Return whether this regular expression is equivalent to other. Two regular expressions are equivalent if they match exactly the same set of strings. This operation takes O(n*m) time, where n and m are the number of states of the DFA of the operands.

    Return whether a string is matched by the regular expression (i.e. whether the string is included in the language generated by the expression). As the match is done using a DFA, its complexity is O(n), where n is the length of the string. It is constant with respect to the length of the expression.
