Hi,

I'm wondering what is the recommended way to manage keywords in a lexer.

I read about testLiterals in ANTLRv2, which disapeared in ANTLRv3. Does
this mean that the "brute force", doing e.g.

FOR: 'for'
WHILE: 'while'
IF: 'if'
...

(my language also have identifiers)

became as efficient as a dictionary-based approach? Is there any other
way?

Thanks in advance,
