hi guys,
I'm writing a pretty printer for the grammar that I
wrote. The grammer file outputs an object
encapsulating the input. So to pretty print it, I
would just walk my object and print out the keywords.
Unfortunately, this approach fails because all
comments are thrown away by my lexer. I attempted to
have my lexer put all the comments into a collection
w/ its row and column information so that I could
insert it during pretty printing. But this falls a
little short, because my objects don't keep track of
every keyword that the lexer returns.
Any ideas? Should I use a AST to do this instead?
Is there any way to search through the archives on the
new mailing list?
