there's any real difference in using Polyparse vs Parsec for this,

Hi,
Can someone provide guidance on how handle operator precedence and
associativity with Polyparse?
Thanks in advance.

Is there a handy list of operators and their precedence somewhere?

Those are all operators in Prelude. See a concrete library for their
operator precedences.

unlike most languages, operators are user-definable in haskell. so
there is no comprehensive list
any function with two arguments van be used as operator:

I'm playing around with Data.Bits. It has .. and .|. which I assume are
functions

Correct?

Hi David,
You're right, I keep forgetting to look at the source code.
And I wasn't aware of the info (:i) command. Should come in handy in the future.

Why there is a default infix? Why it is 9?

Hello.
I am learning how to use Happy (a LALR(1) parser generator) and I have a
question on a grammar based on an example from the manual. The input
file to Happy is attached to this message.
The grammar is:
Exp - let var = Exp in Exp
Exp - Exp + Exp
Exp - Exp - Exp
Exp - Exp * Exp
16 matches
