Hello friends, I want to create a module inside another module with an atom name: For example: defmacro sub_field(name, _type, opts \\ [], do: block) do ast = register_struct(block, opts) quote do defmodule unquote(name) do unquote(ast) end end end If I use Mo…

Weird… when I try this code: defmodule MyLib do defmacro sub_field(name, do: block) do quote do defmodule unquote(name) do unquote(block) end end end end defmodule Example do import MyLib sub_field :opp do def sample, do: IO.inspect(__MODULE__) end end :…

Ah, I see … You have tried my example to create a top-level module in another module. First of all you need to understand something … As same as you can check AST with quote do … end as same you can check how modules are “defined” inside using IO.puts(module). iex> IO.puts(String) Elixir.String i…

Thank you for the time you explain this, but I need to convert atom inside sub_field macro, and user just put an atom Code: defmodule TestNestedStruct do use GuardedStruct guardedstruct do field(:title, String.t()) field(:subject, String.t()) sub_field(:oop, String.t()…

On my phone, so apologies if some of this is incorrect as I can’t test it, but I’d try the following: defmacro sub_field(name, type, opts \\ [], do: block) do ast = register_struct(block, opts) name = name |> Atom.to_string() |> Macro.camelize() |> String.to_atom() …

[image] Eiji: Edit: I have forgot about Macro.camelize/1, so I have updated my code. Thanks @zachallaun ! Credit where it’s due: I just copied it from @shahryarjb ’s post above mine!

Yes this place we can concat the module!! but when I use this inside my macro it does not work and has error. [Screenshot 2023-08-12 at 21.39.29] defmacro sub_field(name, _type, opts \\ [], do: block) do ast = register_struct(block, opts) name = name |> Atom.to_string() …

[image] shahryarjb: MishkaDeveloperToolsTest.GuardedStructTest.TestNestedStruct.Oop. vs what your code do: :oop → "oop" → "Oop" → Elixir.Oop Something in your code tries to reference this long module where it should Oop or you should do other concatenation (not with Elixir, but for example …
