The v4 equivalent would look like:
COMMENT
: ( '//' ~[\r\n]* '\r'? '\n'
| '/*' .*? '*/'
) -> channel(HIDDEN)
;
which will put all single- and multi line comment on the HIDDEN
channel. However, if you’re not doing anything with these HIDDEN
-tokens, you could also skip
these tokens, which would look like this:
COMMENT
: ( '//' ~[\r\n]* '\r'? '\n'
| '/*' .*? '*/'
) -> skip
;
Note that to tell the lexer or parser to match ungreedy, you don’t use options {greedy=false;}
anymore, but append a ?
, similar to many regex implementations.
