ConfigFileTH-0.2: Template haskell for reading ConfigFiles.

Data.ConfigFile.TH

Description

This module provides syntax for concise definitions of config files from Data.ConfigFile through template haskell. For example, the following splice,

$(genConf Example [$conf| elbow/center -> ec :: Double elbow/min -> emi :: Double elbow/max -> ema :: Double |]) resolves into declaration of the following datatype

data Example = Example {ec :: Double ,emi :: Double ,ema :: Double} and a function loadExample :: (MonadIO m) => FilePath -> m (Either CPError Example) , which uses Data.ConfigFile to read a values for the above struct from a file.

Known bugs: Does not support comments in the quotes.
