Import Grammar

In this tutorial we will go over how to import a grammar.

  1. The following grammar is the one we will be importing in this demo. Copy and paste the grammar into a file named example.txt. The syntax of the grammar file was designed to feel familiar to users, as it is very similar to how a grammar would be written on paper.
E -> T EP
EP -> "+" T EP | "-" T EP | ε
T -> F TP
TP -> "*" F TP | "/" F TP | ε
F -> "(" E ")" | "id"
  1. Click the Import Button in the top right of the Main Navigation Bar.
