# BeamInspect
[](https://github.com/appunite/beam_inspect/actions) [](https://hex.pm/packages/beam_inspect)
Inspect how your elixir module looks like in erlang / core erlang.
## Installation
The package can be installed by adding it to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:beam_inspect, "~> 0.1.0", only: [:dev], runtime: false}
]
end
```
## Usage
### Example elixir module
```elixir
defmodule Foo do
def baz do
:a == :b
end
end
```
### Inspect erlang
```elixir
iex(1)> Foo |> BeamInspect.to_erlang() |> IO.puts()
# -file("lib/foo.ex", 1).
#
# -module('Elixir.Foo').
#
# -compile(no_auto_import).
#
# -export(['__info__'/1, baz/0]).
#
# -spec '__info__'(attributes | compile | functions |
# macros | md5 | module | deprecated) -> atom() |
# [{atom(), any()} |
# {atom(), byte(),
# integer()}].
#
# '__info__'(module) -> 'Elixir.Foo';
# '__info__'(functions) -> [{baz, 0}];
# '__info__'(macros) -> [];
# '__info__'(attributes) ->
# erlang:get_module_info('Elixir.Foo', attributes);
# '__info__'(compile) ->
# erlang:get_module_info('Elixir.Foo', compile);
# '__info__'(md5) ->
# erlang:get_module_info('Elixir.Foo', md5);
# '__info__'(deprecated) -> [].
#
# baz() -> a == b.
:ok
```
### Inspect core erlang
```elixir
iex(1)> Foo |> BeamInspect.to_core_erlang(:noann) |> IO.puts()
