Generates datatype declarations with Aeson''s 'Data.Aeson.FromJSON' instances from a set of example .json files. To get started you need to install the package, and run json-autotype binary on an input .json file. That will generate a new Aeson-based JSON parser. Feel free to tweak the by changing types of the fields — any field type that is instance of 'Data.Aeson.FromJSON' should work. You may immediately test the parser by calling it as a script: One can now use multiple input files to generate better type description. Now with Elm code generation support! (If you want your favourite programming language supported too — name your price and mail the author.) See introduction on https://github.com/mgajda/json-autotype for details.'
