Hello!

So I managed to follow the simple “Hello world!” example and then I managed to add my new source code. The name of the package is “PostSPH”. Whenever I try to use a function from there I have to do:

```julia
using PostSPH
PostSPH.function(input)

```

But how does something like, Dataframes, avoid this?

They don’t have to write Dataframes.Dataframe(…)

Kind regards

You’re looking for the `export` keyword:

```julia
module MyModule

export my_function

function my_function()
  println("hello")
end

end

```

The `export my_function` line means that anyone who runs `using MyModule` will be able to call `my_function` without needing to do `MyModule.my_function`.

Thanks! Will do it now, changed question title to better frame the issue for someone else in the future.

Kind regards
