Hello,

Can anyone point me to some documentation that describes how one may set precedence in a user defined operators? I have composition operators so that I can write:

let ruleSuffixCapsFreq = ruleT |> suffixT .> capitalizeT .> freqT

but I seem to be forced to write:

let ruleSuffixCapsFreq = ruleT |> (suffixT .> capitalizeT .> freqT)

and I would like to avoid this.

Hello,

Here's a brief introduction to Haskell fixity declarations:

http://www.haskell.org/tutorial/functions.html#sect3.2.2

Here's the relevant part of the language definition, which includes a precedence table for the operators that ship with the language:

http://www.haskell.org/onlinereport/haskell2010/haskellch4.html#x10-820004.4...

Exactly what I was looking for. Thank you, Hugo F.

Antoine
