OK, I got it to work with gread/gshow.

However I have noticed this:

*Main> (gread $ gshow $ FuncExpr 0 [] (EmptyStmt 0)) :: [(Expression Int, String)] [(FuncExpr 0 [] (EmptyStmt 0),"")]

vs.

*Main> (gread $ gshow $ FuncExpr () [] (EmptyStmt ())) :: [(Expression (), String)] []

Or even narrower:

*Main> (gread $ gshow 1)::[(Int, String)] [(1,"")]

vs.

*Main> (gread $ gshow ())::[((), String)] []

that is, the unit type does not work well with gread/gshow, likely because inner parentheses are not parsed as a constructor.

*Main> gshow () "(())"

Is this a known bug?

I don't think this was noticed before. I wrote it down on the SYB tracker [1]. It should be fixed for the next release. Thanks, Pedro [1] http://code.google.com/p/scrapyourboilerplate/issues/detail?id=9

Thanks.

Bulat,

OK, gread/gshow seem to be like the basis primitives. If they work properly, then it is what is needed.

Thanks.

afaik, SYB just provides gshow/gread functions what serialize any Data instance to String
