Autoload a package

Question

I want to aoutoload a package at the beginning of a notebook. I set up my directory as written here

How to use the Autoload directory?

So, I have these files:

../Work/MyFile.nb

../Work/Autoload/MyPack/MyPack.m

../Work/Autoload/MyPack/Kernel/init.m.

MyPack.m :

ClearAll["Progetto`*"];  

BeginPackage[ "Progetto`"]

    Prova::usage="Prova[]"

    Begin["`Private`"];

        Prova[]:=5+1;

    End[]

EndPackage[]

init.m:

 Get["MyPack`MyPack`"]

In MyFile.nb, I would like use Prova[], but the output isn't 6 but is Prova[].

Where am I wrong? Am I missing something in init.m?

Answer 1

I want to aoutoload a package at the beginning of a notebook.

In this case, create an initialization cell in the notebook, and load that package in that cell. Select the cell, and tick Cell menu -> Cell Properties -> Initialization Cell.

"Autoloading" refers to loading something on kernel startup, and is completely independent of notebooks. This is not what you need.

So, I have these files:

../Work/MyFile.nb

../Work/Autoload/MyPack/MyPack.m

The Autoload directory I wrote about in the answer you are linking to is located in $UserBaseDirectory. There is only one* such directory, and it is used on kernel startup. It does not interact with notebooks in any way.

^{* To be completely accurate, there are a few, but they all live in fixed locations, such as $UserBaseDirectory, $BaseDirectory, $InstallationDirectory/SystemFiles, etc.}
