Hello,
I have a lexer with the following rules:
LBMINUSGT : '[->';
LBASRB : '[*]';
LBAST : '[*';
LBEQUALS : '[=';
LBPLUSRB : '[+]';
LBRACE : '{';
LBRACKET : '[';
MINUS : '-';
The lexer fails(with an error message) when any string of '[-' or '[*' is
detected. I'm confused why ANTLR cannot tokenize '[-' correctly as LBRACKET
MINUS. It also discards two characters after the failed token. I do not have
a static k defined and ANTLR generates no warnings when compiling. I'm still
debugging but it's slow figuring out how the antlr3dfapredict() function
works. Any help is appreciated.
Test input:
foo[-1]
foo[->saf]
foo[*saf]
foo[+saf]
foo[+]saf]
foo[0]
Test output :
frag.v(1) : lexer error 1 :
Unexpected character at offset 5, near '1' :
1]
