Representing regular expressions as strings. Use it much as you would use Boost.Regex, Niche in the world of C++ text processing. Xpressive brings these two approaches seamlessly together and occupies a unique Of regular expressions, which can make it more challenging to author some types In addition, they don't have the exhaustive backtracking semantics
They generally don't allow you to arbitrarily modify your grammar rules on These beasts are more powerful but less flexible. Those tasks have traditionallyīeen handled by parser generators (like the Spirit Tasks such as matching balanced, nested tags. Also, regular expressions are ill-suited to advanced text processing However, that means that syntax errors are likewise not detected until Regular expressionĪnd flexible patterns are represented as strings which can be specified at Options: a regular expression engine or a parser generator. If you need to manipulate text in C++, you have typically had two disjoint Regular expressionsĬan refer to each other and to themselves recursively, allowing you to buildĪrbitrarily complicated grammars out of them. Or as expression templates that are parsed at compile-time. Regular expressions can be written as strings that are parsed at run-time,
