DelphiRegExTests

Regex Testing in Delphi

Simple test program to test finding the word "bad" in a regex string.

Comparing multiple regex engines speeds.

This is not A great test but it gives you an idea. Chaning up conditions would most likely skew results more towards one library than another.

Reason for this was A project I had using Delphi TRegEx took 1.5 hours to run 338 million reg ex calls. While others took 15 minutes or less once I moved away from it.

You will need to change up the code to fit your needs depending on what your regex string is and what you are trying to accomplish.
