AlphaRegex is a synthesizer that instantly outputs regular expressions from examples for introductory automata classes, This work was conducted under the guidance of Prof.Hakjoo Oh (http://prl.korea.ac.kr) in Korea University.
AlphaRegex performs over- and under approximations
of partial regular expressions to accelerate the speed.
For the more details, please refer to
our GPCE '16 paper Synthesizing Regular Expressions from Examples for Introductory Automata Assignments.
Please cite our paper if you find our work is intriguing.
After you clone this project, follow the steps below.
- Activate the build script:
chmod +x build. - Complie the whole files using the script:
./build.
To use AlphaRegex, you need to provide:
- Positive examples
- Negative examples
Then, AlphaRegex quickly derives a regular expression
that accepts all the positive examples and
rejects all the negative examples.
For example, type ./main.native -input benchmakrs/no1_start_with_0,
then AlphaRegex instantly generate the solution 0(0+1)^*.
In the benchmarks directory, there are benchmark examples
that we used for evaluation and you can easily check
how positive/negative examples should be given to AlphaRegex.
AlphaRegex is maintained by Programming Research Laboratory in Korea University (http://prl.korea.ac.kr). If you have any questions, feel free to email us: [email protected], [email protected]
