Hi @gordonguthrie this is cool, please bare with me, I'll get to it shortly |

Match in the function clause instead?

|
|

| ```elixir | ||
| Decompilerl.summarise('_build/dev/lib/myapp/ebin/Elixir.MyApp.AuthController.beam') |

It's uncommon for elixir APIs to accept lists as "strings", since strings are binaries by default. What do you think?

my bad, there's a typo there: decompierl

IMO it'd be more idiomatic to match (preferably in the function clause) like this:
%{file: file, module: module, ...}| format(behaviours, "Behaviours : "), | ||
| format(exports, "Exported Fns : "), | ||
| get_private_functions(functions, exports) | ||
| |>format("Private Fns : ") |
| lines = [ | ||
| "File : " <> file, | ||
| "Module : " <> module, | ||
| format(behaviours, "Behaviours : "), |

Would you consider using String.pad_trailing/3 for all the formatting touch ups?
| get_private_functions(functions, exports) | ||
| |>format("Private Fns : ") | ||
| ] | ||
| Enum.join(List.flatten(lines), "\n") |

There's no need to flatten, iolists are OK to write
| append_value(map, :behaviours, [Atom.to_string(behaviour)]) | ||
| end | ||
|
|
||
| defp process_ast({:function, _, func, arity, _body}, map) do |

Perhaps glue the function clauses together, i.e. no white space in between?
| end | ||
|
|
||
| defp make_fn_declaration(func, arity) do | ||
| Atom.to_string(func) <> "/" <> Integer.to_string(arity) |
|

| %{^key => values} = map | ||
| Map.put(map, key, values ++ valuelist) |

You could avoid matching and pinning the key with:
Map.update(map, key, xs, &(xs ++ &1))
