This is a program to convert a NFA into a DFA. The CLI can read the definition of the NFA from JSON and output it either as JSON or in the DOT format.
git clone https://github.com/czwinzscher/nfa-to-dfa.git
cd nfa-to-dfa

nfa-to-dfa -f example.json --output-json
# output in dot format and use the dot program to create an image
nfa-to-dfa -f example.json --output-dot | dot -Tpng > out.png
# read from stdin and write to file
cat example.json | nfa-to-dfa --stdin --output-dot -o out.dot
