I would be glad to create that issue but I really don’t know how what I would say.
I ran this code:
defmodule MyApp do
def hello do
default(11_111_111)
end
@spec default(binary) :: binary
def default(bin) when is_binary(bin) do
"test #{bin}"
end
def debug do
__MODULE__
|> :code.which()
|> :beam_lib.chunks([:debug_info])
|> IO.inspect(label: "debug")
end
end
And it gave me the following result:
:ok,
{MyApp,
[
debug_info: {:debug_info_v1, :elixir_erl,
{:elixir_v1,
%{
attributes: [],
compile_opts: [],
definitions: [
{{:hello, 0}, :def, [line: 2],
[{[line: 2], [], [], {:default, [line: 3], [11111111]}}]},
{{:default, 1}, :def, [line: 7],
[
{[line: 7], [{:bin, [version: 0, line: 7], nil}],
[
{{:., [line: 7], [:erlang, :is_binary]}, [line: 7],
[{:bin, [version: 0, line: 7], nil}]}
],
{:<<>>, [alignment: 0, line: 8],
[
{:"::", [inferred_bitstring_spec: true, line: 8],
["test ", {:binary, [line: 8], []}]},
{:"::", [line: 8],
[
{{:., [line: 8], [String.Chars, :to_string]}, [line: 8],
[{:bin, [version: 0, line: 8], nil}]},
{:binary, [], []}
]}
]}}
]},
{{:debug, 0}, :def, [line: 11],
[
{[line: 11], [], [],
{{:., [line: 15], [IO, :inspect]}, [line: 15],
[
{{:., [line: 14], [:beam_lib, :chunks]}, [line: 14],
[
{{:., [line: 13], [:code, :which]}, [line: 13], [MyApp]},
[:debug_info]
]},
[label: "debug"]
]}}
]}
],
# ...
I do not have knowledge about the compiler but to me it looks like the line numbers are set.
