[antlr-interest] Re: Problems with EOF

[Xue Yong Zhi]

Please explain your problem in a better way. I do not understand what do 
you mean by "the parser stay on cycle and do nothing". I think the 
parser will terminate anyway if it meets EOF. Can you give the shortest 
grammar which can duplicate your problem? For example, something like this:

program:
	:	(SL_COMMENT	|	ML_COMMENT)	EOF
	;
