introduce - grammarware/slps GitHub Wiki

A definition of a fresh nonterminal is added. The addV operator should be used instead, if the nonterminal is already defined, is to be merely extended. The define operator should be used instead, if the nonterminal is readily in use, but merely lacks a definition.

introduce:
        production+

For instance,

a:
        b
b:
        ε

After using this transformation:

introduce(
 c:
        a
 c:
        b
);

Will look like this:

a:
        b
b:
        ε
c:
        a
c:
        b
