Equivalent of python eval in Haskell

Question

There is function in python called eval that takes string input and evaluates it.

>>> x = 1
>>> print eval(\'x+1\')
2
>>>         


        

Answer 1

There is no 'eval' built into the language, though Template Haskell allows compile time evaluation.

For runtime 'eval' -- i.e. runtime metaprogramming -- there are a number of packages on Hackage that essentially import GHC or GHCi, including the old hs-plugins package, and the hint package.
