I've ported DScanner over to this new lexer code. It's on a branch here:
https://github.com/Hackerpilot/Dscanner/tree/NewLexer.
One limitation I've noticed with the new tok!"tokenName" approach is
that while dmd has no problem with
case tok!"class":
it does have a problem with
goto case tok!"class":
I managed to work around this by adding new labels and "goto"-ing them
instead. Is this a bug or intentional?
I cannot reproduce your problem. If this does not work, it is a bug.
The problem is that tok is a dynamic value. It should be a static value.
Current code:
static @property IDType tok(string symbol)()
{
...
}
It should be:
template IDType tok(string symbol)()
{
alias tok = ...;
}
This is important - if the compiler thinks tok is a dynamic value, it'll
generate crappy switch statements.
BTW @Brian - I didn't look at this in depth yet but it's very promising
work. Thanks!
