Simple question on loading programs in emacs

Simple question on loading programs in emacs

[Haines Brown]

A simple question, but I'm lost in the manual. I want to start a session
of emacs that automatically loads an emacs program automatically instead
of having to do M-x program during the emacs session. I want to do this
because I have a custom emacs init file just for that emacs program.

I tried (autoload 'program "ProgramName" t), but this only sets it in
the environment. 

A related question: When I close that program within emacs, I want
it to close the emacs session as well.

Hi Haines,

perhaps you can tell what program you want to load?

It will help us getting a more precise idea on how 
to help.

Best,

You can just call that program frmo your custom emacs init file:

----(program-init.el)-----
(program)
--------------------------

and run it with:

emacs -q -l program-init.el

What do you mean by "closing that program"?

You can call the (kill-emacs) function, but the question is where/when
to call it?

Most of the emacs programs don't have a `main' function (as in C
programs).  First you load a file, then you run a command.

For a fun example, consider tetris.

,----
| First you load the file with
|    M-x load-library RET tetris RET
| 
| Then you run the tetris program with
|    M-x tetris TAB TAB (there are two tabs)
| 
| So now you know what all you could do.  If you click on tetris with a
| mouse the game will start.
| 
| Now you find that you are losing fast and you want to stop the game.  So
| again you do
|    M-x tetris TAB TAB 
| 
| You click on tetris-end-game and you are done.
`----

,----
| For another fun example, you can do
|     M-x butterfly RET
`----

,----
| Now you do 
|     M-x list-command-history RET
| 
| You will see what all you did.  You will see lines like 
| 
|     (tetris)
|     (tetris-end-game)
`----

,----
| For automatically running tetris, create a file with name .emacs in your
| home directory and copy paste the first line.
| 
|     (tetris)
| 
| and then start emacs normally.
`----

You are done.

Now you have to do
    C-h t

and read the manual.

Maybe Emacs Batch Mode is what you're looking for.  See

In batch mode you don't have a user interface.  Probably, the OP program
will have some user interface and interactivity, since "*I*" will close
it.
