Why "it must"? You need it to be lower-case? Or parsing does not work if it is
not lower-case?
Maybe I did not understand correctly what you want...
I thought you wanted to recognize
BuyOrSell something
buyORsell something
using a single rule, say
buy : [ [ "buyOrSell"; ... ] ]
If that is the case, I think my solution works.
You might even do that:
buy : [ [ "buy_or_sell"; ... ] ]
and at lexing time do
if String.lowercase s = "buyorsell" then
IDENT "buy_or_sell"
else
IDENT s
In this case it is more than a matter of case, but the argument is still valid:
I have declared a rule with "buy_or_sell", so the rule will be taken when a
"buy_or_sell" keyword is found, and the lexer produces "buy_or_sell"
identifiers from anything that matches case-insensitively "BuyOrSell".
Cheers,
Matthieu
