Happy Parser
Hello..
I totally new to happy and I cannot manage to run a happy example. I downloaded Calc.ly example from the following link
http://darcs.haskell.org/happy/examples/
I run happy on the example and succesfully created the Calc.hs file. In Haskell,hugs I can load the Calc.hs file and at the console I have Calc> name, meaning that the program was loaded.
As I understood the grammar it should be a minicalculator.
What I could not manage to do is how an expression should be written? (a simple expression like - 1+2)
Please help
