Testing Alphabet Learner

Please cd grepy twice. So cd grepy..... cd grepy Then to test the Alphabet Learner use the command: python src/alphabet_learner.py data/inputFile1.txt

It returns any number or alphabet letter from the inputFile1.txt. It then asks if you want to enter a word to find from that file and returns it. You can modify the file inputFile1.txt and test it using different words or find letters in a word.

Heres an example: youssefabdelhady@Youssefs-MBP grepy % python src/alphabet_learner.py data/inputFile1.txt

Alphabet: ['2', 'B', 'C', 'F', 'H', 'I', 'K', 'O', 'S', 'T', 'Y', 'a', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'r', 's', 't', 'u'] Enter a word to find: or C[or]neliusTheC[or]n

Testing Regex to NFA

Go to the src directory So cd grepy....cd grepy....cd src run: python rungrepy.py

Enter a regex, and it will test the NFA and DFA with the inputFile2.txt strings.

From there it tests the NFA, converts the NFA to DFA and tests the data on the inputFile2.txt

And returns the dot format for DFA.

Example: Enter a REGEX: ab
