SYNOPSIS

This example illustrates a way to set a naming scheme for the grammar productions using give_token_name.

give_token_name: The name of the production is the Left Hand Side of the Production Rule followed by the word _is_ followed by the concatenation of the names of the tokens in the right hand side (separated by underscores).

Compile it with: eyapp -b '' give_token_names.eyp and run it: $ ./give_token_names.pm -t -c '*a = b'

It will produce an output like:

s_is_ASSIGN(l_is_STAR(r_is_l(l_is_VAR(TERMINAL))),r_is_l(l_is_VAR(TERMINAL)))

The main difference between this file and give_names_to_tokens.eyp is that the tokens in the right hand sides are already identifiers: ASSIGN and POINTER.
