Accesing A Module's Structure

Questions / Help
1

How does one access/create the structure Inode, defined below, from another module?

defmodule Cont.Expr do

  defmodule Inode do
    defstruct value: 0
  end

end
2 
inode = %Cont.Expr.Inode{}
3

Tried that and got:
(CompileError) Cont.Expr.Inode.struct/1 is undefined, cannot expand struct Cont.Expr.Inode

Actually I think this might be a problem with the Atom/Elixir because I can compile and run this code

inode =  %Cont.Expr.Inode{value: 1234}

IO.inspect inode

And it ouputs

%Cont.Expr.Inode{value: 1234}

And Atom/Elixir displays this:

(CompileError) Cont.Expr.Inode.__struct__/1 is undefined, cannot expand struct Cont.Expr.Inode

Where are you placing your files? How is you or your editor compiling them? mix compile?

Yeah I’m using mix(mix escript.build) to compile and I’m placing all the files in the projects lib folder which is generated by mix new main.

I would double check the file extensions. If that still does not work, can you push the project to Github or something that reproduces the error?

Here you go. This reproduces the error I am having with Atom/Elixir.

I could not reproduce it. What is your Elixir version?

My Elixir version is 1.3.3

I wonder if its a problem with the plugins with Atom because Eliixir will compile the code without complaint but the Atom editor+plugins will display the posted error message.

That sounds like it. Try filing a report on their elixir plugin/extension.

I’m just glad that issue is solved(for me). Do you know how confusing it is to see an error pop-up in the editor indicating something is incorrect when it really isn’t?

Thank-you everyone for helping with this problem. I’ll file the report today.
