Re: [Haskell-cafe] Design of a DSL in Haskell

Rusi, I have "read" Fowler's book.(that is focusing on Java by the way) and could not find the answer there, I think it is a typical textbook. I think this is a good start by the way: http://www.cse.chalmers.se/edu/year/2011/course/TIN321/lectures/bnfc-tutoria... --Joerg On Dec 2, 2012, at 5:45 PM, Rustom Mody wrote:

I am working on a DSL that eventuyally would allow me to say:

import language.cwmwl main = runCWMWL $ do eval ("isFib::", 1000, ?BOOL)

I have just started to work on the interpreter-function runCWMWL and I wonder whether it is possible to escape to real Haskell somehow (and how?) either inside ot outside the do-block.

I thought of providing a defautl-wrapper for some required prelude functions (such as print) inside my interpreter but I wonder if there are more elegant ways to co-loacate a DSL and Haskell without falling back to being a normal library only.

+1 I am also interested in the DSL-in-Haskell possibilities

[I am assuming Joerg that you're familiar with the basic ideas and terminology like http://martinfowler.com/bliki/DomainSpecificLanguage.html and the links therein]
