chmod +x ./bin/console

./bin/console

In the console, you can use the following commands:

• tokenize(<input>): Tokenize the input string using the grammar defined in the loaded grammar.
• parse(<input>): Parse the input string using the grammar defined in the loaded grammar.

The default grammar is defined in ./src/samples/math.js. You can define your own an export it from a file, then import it in the console and use it.
