[antlr-interest] please help on lexer rules antlr v3

[Michiel Vermandel]

John,

Sorry, I forgot to mention that I reduced my test string to "--axi.reject"
, so without the space.
I have done this to strip out every part that is not really crucial.
So even with the "--axi.reject"  test string the grammar I have sent in my 
previous mail results in an EarlyExitException...

I tried as wel to change the rule  to 
SL_COMMENT:  '--' ( ((TAB|SPACE)* ('axi.locate' | 'axi.reject')) | ( 
ANYTHING_2_EOL { channel=90; }) );
but the problem remains...


Please help?

You forgot to allow for whitespace between the '--' and 'axi...'

Your modified grammar accepts "--axi.reject".
