ANTLR Paraphrase, what does it do?

Question

Just starting to write my first lexer and i've come across this:

RPAREN options { paraphrase = ")"; } : ")";

I'd like to know what paraphrase actually does, does it mean that in this case RPAREN can also be used as simply ) in the parser?

thanks!

EDIT - just found this online

We can use paraphrases in Rules to make error messages user-friendly

is this correct?

Answer 1

paraphrase is not a valid option in ANTLR 3 or ANTLR 4. Including it would either produce a warning or error, and it would not have any impact on behavior.
