Issue with .emacs, files not loading

Issue with .emacs, files not loading

[Chris Poole]

I used to have everything in one .emacs file.

Now I've split it up into various files for different systems (I use
Mac OS X and GNU/Linux).

This is my .emacs file:

;; Check to see if running on Mac OS X or some GNU/Linux distro
(defvar macosx-p (string-match "darwin" (symbol-name system-type)))
(defvar linux-p (string-match "gnu/linux" (symbol-name system-type)))

;; Load stuff for GNU/Linux systems only
(when linux-p
  (setq load-path (append load-path (list "~/emacs/lisp/linux"))))

;; Load stuff for Mac OS X only
(when macosx-p
  (setq load-path (append load-path (list "~/emacs/lisp/macosx"))))

;; Load OS-independant stuff
(setq load-path (append load-path (list "~/emacs/lisp/generic")))

;; Load extra major modes (to top of load-path so loads first)
(setq load-path (cons "~/emacs/lisp/generic/org" load-path))

Inside ~/emacs/lisp/generic, I have all my settings in my-custom-
generic.el. (Not byte-compiled yet.) I also have several other files.
None of them load. Similar situation with the macosx directory, etc.

The final loading of org-mode does load though, replacing the version
that came with Emacs.

I can't see what I'm doing wrong -- can anyone tell me my stupid
mistake?

Thanks.

Chris,
 From the variable's documentation

   *List of directories to search for files to load.
   Each element is a string (directory name) or nil (try default directory).

   Note that the elements of this list *may not* begin with "~", so you must
   call `expand-file-name' on them before adding them to this list.


You need to expand your paths before adding them to load-path.
I can't see where you are calling (load-library) to load
my-custom-generic.el.

HTH,

Where did you get that?  Here it says:

,----
| *List of directories to search for files to load.
| Each element is a string (directory name) or nil (try default directory).
| Initialized based on EMACSLOADPATH environment variable, if any,
| otherwise to default specified by file `epaths.h' when Emacs was built.
`----

No mention of expand-file-name.

Huh?  I have

(setq load-path (append (list "~/elisp") load-path))

in my .emacs since ages, and that has always worked.

That's a valid point, at last.

"~" is an acronym that UNIX shells understand. It's not part of a  
path specification. GNU Emacs seems to do the right thing in some  
instances. Using the expand-file-name function, let's say ten times  
in ~/.emacs, wastes after a few thousand launches a measurable amount  
of time and energy – and conserves far more when you don't protect/ 
expand ~. What is ~ meaning in Losedos? What is C:\ meaning in UNIX?  
Or classic Mac OS 8 or 9?

Thanks.

I have the same definition for load-path as you do (not mention of
having to expand the path). And anyway, it works fine to load org-mode
without expanding the path.

But I'm afraid I'm new to elisp. I was under the impression that by
adding ~/.../generic to my load path, it would read all elisp files in
that directory, executing everything.

What do I have to do with load-library?

Re: Issue with .emacs, files not loading

[Chris Poole]

OK, sorted it.

I didn't realise I had to manually load all the files in my load path
directories with load-library.

Added these commands, and now it works great.

Thanks.

Emacs understands it as well.

What exactly does it waste?

> What is ~ meaning in Losedos?

Same as on Unix: the home directory.

> What is C:\ meaning in UNIX?  

A file named "C:\".
