see what happens when you ditch the eval-after-load completely. i
suspect that installing tabbar-mode through elpa already activates it,
so what you're doing with the eval-after-load call is deactivating it
again...

this is wrong. it should be:

    '(progn

>          )

note: the common way to write lisp is to not put the closing parens on a
separate line. just write:

(eval-after-load "color-theme"
  '(progn
     (color-theme-initialize)
     (color-theme-hober)))

looks much cleaner. (the parens are just there for the computer. as a
human, you should ignore them and look at the indentation.)

this is telling you that (color-theme-initialize) cannot be a function
(nor name one). which is correct, because it's a list. a list can only
be a function if its first element is the symbol `lambda'.

the reason why emacs thinks (color-theme-initialize) is a function is
because you've misplaced the paren with progn.

use the code snippet i gave above, it should (hopefully ;-) work.

Still the problems, but I saw that emacs 24 has it's own way of handling color themes, and that is
what I am using:

(load-theme 'wheatgrass t)

Good point - I am used to pascal, R and a bit of C, where the brackets are closing on the new
lines, but I agree - if one looks at the indentation, it is quite easy to understand.

Hm - i would say many things still to learn.

Thanks a lot for your explanations,

Not quite.  Emacs 24 has its own way of handling color schemes, in the general
sense of the word.

Emacs 24 has nothing to do with color themes.  It has a similar but separate
feature, called "custom" themes.  This is different from color themes, which are
what library `color-theme.el' is about.

Activating tabbar after installation via elpa on emacs 24.2.1

Hi

I just decided to install some standard packages via elpa, and I am running into problems with two
packages: tabbar and color-theme

I would like to acivate them in .emacs.d/emacs.el and start the tabbar-mode and set color-theme-hober

I tried
  (eval-after-load "tabbar"
      '(tabbar-mode)
    )

but this activates the tabbar mode, but does not show them. I have to disable it and enable it
again and then can I see the tabbar.

(tabbar-mode)

tells me

Debugger entered--Lisp error: (void-function tabbar-mode)

I get a similar error for

(eval-after-load "color-theme"
  'progn(
         (color-theme-initialize)
         (color-theme-hober)
         )
  )


Debugger entered--Lisp error: (invalid-function (color-theme-initialize))
  ((color-theme-initialize) (color-theme-hober))

even though I can execute ALT-x color-theme-initialize

I guess I am missing something basic...

Any ideas?

Thanks,

Rainer

I think it should be 

  (eval-after-load "tabbar"
      (tabbar-mode))

(no quote)

Btw, ELPA packages are initialized *after* Emacs loads your init file.
So it may often be a good idea to add (package-initialize) very early
in your init file, after you set the package-* options correctly.

Thanks - elisp is still a real challenge for me - I should spend some time on it.

You are perfectly right here - this is the cause of the problem. I put (package-initialize) in my
init.el and it worked (after the other changes).

But what do you mean with package-* options?

I only set

(setq package-archives '(
                           ("ELPA" . "http://tromey.com/elpa/")
                           ("gnu" . "http://elpa.gnu.org/packages/")
                           ("suco" . "http://joseito.republika.pl/sunrise-commander/")
                           ("marmalade" . "http://marmalade-repo.org/packages/"))

and that in my emacs.org (el) file - should I move this into the init.el, or call
(package-initialize) in my emacs.org (el) file after I set the parameter?

Thanks,

Rainer

Hi Rainer,

I mean `package-load-list' in particular.  

This defaults to '(all), which loads all packages that you downloaded
through M-x list-packages RET but you may want to load only some.

You should move this before (package-initialize), otherwise Package will
not be aware of these ELPA repos.

OK - was wondering already if it is loading all packages, which might be delaying the start and
using more memory.

OK - but could I should be able to put these statements as first commands into my emacs.org - correct?

eval-after-load is a funtion, so the form to be executed *should* be quoted.

Thanks - this is the problem if one is copy-paste without knowing what these things mean - I stil
think elisp is kind of strange, ur rather unusual for me.
