[Derivco Sweden Hackathon 7] compare configurations in .exs and .sys.config format

ConfigComparator

Used to compare erlang sys.config configuration file with the elixir .exs configuration file.

Installation

If available in Hex, the package can be installed as:

1. Add config_comparator to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:config_comparator, "~> 0.1.0"}]
end
```

2. Ensure config_comparator is started before your application:

```elixir
def application do
  [applications: [:config_comparator]]
end
```

Commands

Example usage:

ConfigComparator.Comparator.compare({{path_to_sysconfig}}, {{path_to_elixir_config}})

Example output:

Difference found: {{:foo, foo}, :foo}
In exs config: [%{country: "England"}]
But in sys.config: [%{country: "England"}, %{country: "Germany"}]

Difference found: {{:bar, bar}, :bar}
In exs config: 90
But in sys.config: 100

No difference found!
