Initialization customization not being saved : solved !

Initialization customization not being saved : solved !

[Allan J Mui]

Sorry, I have found the problem and the feature is now working properly. I
had byte-compiled my .emacs.el initialization file and failed to
byte-compile again after making the "Inhibit Startup Screen" variable
customization. I also ignored the warning message generated by emacs at
startup : "_emacs.el" is newer than "_emacs.elc" .

Thank you for your attention and I appreciate the new version very much.

sessions" and click "Finish" it appears to work but when I restart Emacs
the setting is back to the default of "off". The Startup screen is still
being displayed.

Emacs could

(1) warn the user when saving the customized value that .emacs must be
     byte-compiled in order to apply the customized value when Emacs is
     restarted (even if a warning is issued only once during a session
     people may find this annoying),

(2) warn the user when exiting Emacs that there were uncompiled saved
     values (won't help much when a user just fires another instance of
     Emacs in order to quickly test a customization),

(3) warn the user very explicitly at startup - maybe asking questions
     like "byte-compile your .emacs now?" or "reload .emacs source?",

(4) automatically load the uncompiled .emacs and warn the user that it
     has _not_ been compiled (confusing, why should .emacs be treated
     differently from other files).

I'd opt for (3) although I generally hate programs asking me questions
during startup.

I use the following in my site-start.el:

    (when (file-exists-p source-file)
      (require 'bytecomp)
      (let ((byte-file (byte-compile-dest-file source-file)))

(5) Warn the user that byte-compiling his file is *strongly* discouraged.

(6) Never even look at ~/.emacs.elc

That's fair, if you can turn it off.

That's not.

Why would you ever want to byte-compile your .emacs file?
If it's really large and with functions that use loops and macros and
can hence benefit from byte-compiling, then you should move that part
out to another file.

It is. Not *very* large, but about 1.500 non-comment, non-empty lines.

Why? All this is loaded unconditionally. Why manage two or more files,
when one is fine?

As I've shown, I have code to detect a stale init.elc and
automatically recompile it, so there's no problem whatsoever with
having it all in one file. That's my preferred setup. If Emacs
suddenly refused to load .emacs.elc/init.elc, that would be extremely
unnice.

So I'd strongly encourage you to remove the corresponding note in the
Emacs manual saying:

If you have a large amount of code in your `.emacs' file, you should
rename it to `~/.emacs.el', and byte-compile it.  *Note Byte
Compilation: (elisp)Byte Compilation, for more information about
compiling Emacs Lisp programs.

Yes, please remove it,

I have a better suggestion: Please explain how, when a .emacs file gets
too big, a user can splice out parts to a separate file, where to store
that file, byte-compile it, and how to load it from .emacs.

Do *not* byte-compile your .emacs file.

I have added to the end of my .emacs:

;; Local Variables:
;; no-byte-compile: t
;; End:

With kind regards,

Re: Initialization customization not being saved : solved !

[Allan Mui]

I agree that it is not necessary but I also have my `.gnus.el' file
byte-compiled and it is even smaller than `.emacs.el' .
It seems that if someone wants to do this they should be able to remember
to do it again after making changes using customization buffers such as
"Initialization". After all, it is equivalent to manually editing the
`.emacs.el' file. It seems hardly worth coding around such a simple issue.
I had simply failed to look in the `message' buffer for the warning.
