Regen is Regular Expression Generator, Compiler, Engine.

for High-speed regular expression matching, Regen gnerates

native code from regular expression (require Xbyak).

also Regen makes matching as parallel (require boost::thread).

* install

move to source directory

% cd src

and build Regen

% make all

or build Regen with no JIT-ver

% make REGEN_ENABLE_JIT=no

or no Parallelization.

% make REGEN_ENABLE_PARALLEL=no

or enable neither.

% make REGEN_ENABLE_JIT=no REGEN_ENABLE_PARALLEL=no

* test and behcnmarks

% make test

% make benchmark

or try manually

% make test.o && ./test.o -t THREAD_NUM {-O olevel}

% make bench.o && ./bench.o {-O olevel}

* caluculate number of NFA/DFA/SSFA's states.

% make state_num

% ./state_num [-m -n -d -s] (REGEX | -f REGEX_FILE)

minimization option: DFA minimization(-m).

target option: NFA(-n), DFA(-d), SSFA(-s)
