Talk: Compile Time Regular Expressions
I will present a library that utilizes a feature of C++20 to build regular expressions from compile-time strings.
This is a novel approach that doesn't have ordinary disadvantages of other regular expression implementations like having to use a linked library or a run-time cost of parsing and interpreting an internal finite machine. You will see implementation details of the library and problems I have run into during its writing. In the last part of the talk, I will compare other implementations of regular expression engines and show compiled code in Compiler Explorer.
