I have a large group of regular expressions, over 300 that I need to use against a large group of files (about 10,000) to find all matches.
I've looked at Google's re2 and find it might be useful for speed.
I need code in C++ that runs from a Linux command line that will read a library of regular expressions and will accept a path to a folder with files in it. The program will check each file for all the regular expressions looking for all the matches.
The regular expressions will change frequently so I need an easy way to create the library of regular expressions.
It should run fast and efficiently.
