This is the source code repository for RE2, a regular expression library. I modified it for building static DFA and dynamic DFAs.
getDFA.ccp can accept one argument for Static DFA or two arguments for Dynamic DFA.
To compile getDFA use the following command:
g++ -v getDFA.cpp -g -o getDFA -std=c++11 -pthread -I/home/peipei/re2/ -I/usr/local/include -O3 -L/home/peipei/re2/obj -lre2

For documentation about how to install and use RE2,
visit https://github.com/google/re2/.

The short version is:

make
make test
make install
make testinstall

There is a fair amount of documentation (including code snippets) in
the re2.h header file.
