[Haskell-cafe] Small language with parser in Haskell and Faker

Hi all!

As for beginner – it was pretty hard to me to parse YAML or JSON. Too much
information, too much functions for such a simple task (in Ruby it is
really simple, because of duck typing). So I wrote mine super simple
language for data files – Giml – and two parsers for it – in Ruby and in
Haskell. Aim of this language - to be fast and so simple that you need only
couple pages of code of any language without heavy dependencies to
implement parser. Here is the manifest: https://github.com/gazay/giml.
Parser in Haskell: https://github.com/gazay/gimlh

It was written mostly for my library Faker, which was nicely discussed on
reddit (
so I have a lot of plans what to do in future with Faker. But I didn't
present Giml anywhere and it will be really great if someone can take a
look (there only couple pages of code) and tell me what can be improved,
what can be rewritten in better way and so on. I didn't use Parsec for a
reason in this library as I wanted to write my parser as clean of
dependencies as possible, but maybe it will improve performance or
something else?
