User setup for emacs

User setup for emacs

[tolugboji via Users list for the GNU Emacs text editor]

I have my own setup for emacs. I want to have a .emacs that links with my settings by calling typex.el
located in

/home/tolu/Opstk/bin/typex/typex-1.0/typex.el

What do I have to do?

I have done this

(add-to-list 'load-path "/home/tolu/Opstk/bin/gadin-1.0/typex/")
(load "typex")

What does a typical .emacs look like?

A lot of `setq' for settings/options:

  (setq auto-save-no-message       nil)
  (setq auto-save-list-file-prefix nil)
  (setq make-backup-files          nil)
  ;; ...

But if you have a file somewhere and want to keep it like that
there is no harm `load' or `load-file'ing it from ~/.emacs ...

I work to improve them and for others to find useful information.  I do not see that
emacs provides a .emacs dering installation.

The article claims that the latest way to include customisations is via ~/.emacs.d/init.el
rather than using ~/.emacs.  Is this claim correct?

It doesn't if you by installation mean the placing of binaries
etc in $PATH directories and such stuff ...

But I like it that way, I don't like when Emacs adds stuff to
my init files and I see no advantage of that, on the contrary
I'd keep that human/computer separation clean.

Also I have no idea why this "has to" be the way it is but
with this at least I don't have to see it

  (setq custom-file "~/ooa/dork.elc")

I don't even use custom so why can't that be opted out
completely? Or can it? Apologies if so ...

Well, to me the init files were just files, the only thing
setting .emacs apart is that Emacs by default looks for it,
i.e., looks for a file located in $HOME with that name.
But I don't know, maybe there is indeed a policy which is
wholly or in part enforced somehow with respect to specific
files ...

The problem I find is there is no guide on how to get emacs to access
the user customisation files. Perhaps there could be an init file with
the lines commented out, and then one can add the paths etc to the user
customisation.

But loading files in general and the Emacs init process is
described in the Emacs and/or Elisp manuals ...

If you don't like that, try the on-line help:

  C-h f load-file RET

and so on.

I was guided to some emacs wiki and read a good article by Xah Lee, which helped.

Re: User setup for emacs

Hi Tolugboji,

the Emacs Wiki has some pages about init files:

  https://www.emacswiki.org/emacs/InitFile
  https://www.emacswiki.org/emacs/CategoryDotEmacs

My ~/.emacs is totally atypical but it is here:

  http://angg.twu.net/.emacs
  http://angg.twu.net/.emacs.html

I set custom-file to another file - ~/.emacs.custom - because I don't
understand customize well and I used to feel very scared everytime
that customize changed something in my ~/.emacs without showing me
what it was doing. The part of my ~/.emacs that sets this is:

  (setq custom-file "~/.emacs.custom")
  (load custom-file)

It is at:

  http://angg.twu.net/.emacs.html#.emacs.custom

Have you tried rcirc? Its manual is here,

  (info "(rcirc)Top")
  https://www.gnu.org/software/emacs/manual/html_node/rcirc/index.html

and here is a link that explains IRC in more detail:

  http://www.irchelp.org/faq/new2irc.html

You just need to run M-x rcirc, and then once you're connected you can
issue commands like "/nick tolug" and "/join #emacs".

  Cheers,
    Eduardo Ochs

Quite right.  Had experienced that problem before.  Emacs does something
and the next I load emacs, weird things happen.  Can take time to figure out
what happened.

The part of my ~/.emacs that sets this is:

Was not aware of rcirc, no.

IMHO, everyone should define `custom-file', and
thus keep Customize's maintenance of the code
it generates away from the code you write in
your init file.  To me, this is common sense.

But I was unable to get Emacs to even recommend
using `custom-file', let alone programmatically
encourage (not quite enforce) its use.

Quite unfortunate.  It takes a lot of convincing and changes very slow.
I would like to ask if the link to the user-customisation files should
be done from ~/.emacs.d/init.el.

Is the latest way to do so in ~/.emacs.d/init.el rather than from ~/.emacs?

You can load it from any file that you load,
any time.

So yes, you can load it from your init file
(or from any file that your init file loads).

The point at which you load it is up to you.
You might want/need some Customize settings
to be in effect before (or after) you do
some other things in your init file.

Does emacs customarily use ~/.emacs.d/ ?

Yes, and you can put your stuff, or some of it, there as well.

[M]ELPA packages end up there, and also tramp, abbrev_defs,
and more.

No idea if I could answer your question, but what
do you mean by "disable custom"?  What do you mean
by "custom"?  What is it that you're really trying
to do or asking about?

Customize user options start with `custom'.
I see these, using completion:

I don't want it to write options, not any options and not to
any file. Because I handle my own options.

So if there is an option to disable it, that's what
I would do.

The functions that write to a file have both
`custom' and `save' in their names.  But you
might invoke some other function that in turn
calls one of those.  Here are those I see:

custom-face-save
custom-group-save
custom-reset-standard-save-and-update
custom-save-all
custom-save-faces
custom-save-variables
custom-theme-save
custom-variable-save
customize-push-and-save
customize-save-customized
customize-save-variable

Ah, right. That's true.

Well, how do you find that out? Is there a method for that?
I mean in general ...
