How to debug problem with emacsclient and init file

How to debug problem with emacsclient and init file

Hi, I an running Emacs 23.1.1 on arch linux. I start the emacs daemon
in my ~/.xinit file (emacs --daemon &) and can open new emacsclients
in the terminal with no problems, but when I try

$ emacslient -c

the line "Waiting for Emacs..." is printed and nothing else. If I add
the -n option:

$ emacsclient -nc
*ERROR*: Undefined color: "unspecified-bg"

So I tried starting the emacs daemon without my init file and
everything is fine -- I can open graphical emacsclients. This seems
weird because I can open a new (X or terminal) emacs without getting
any complaints about the init file. I thought about adding my init
stuff back in gradually but there's rather a lot of it, and I wondered
if there is a better way to debug this problem?

Thanks,

I'm not sure this even works when going thru emacsclient but does
turning on  debug-on-error show you any more userfull info:

Put:
 (setq eval-expression-debug-on-error t) 

Into ~/.emacs to find out.

Hi Harry. This has no effect -- the daemon starts without any errors
and the graphical client won't start. Commenting stuff out of .emacs
I've found I can start the graphical client without a color theme, or
if I do this:

(defmacro Xlaunch (&rest x)
  (list 'if (eq window-system 'x) (cons 'progn x)))
(require 'color-theme)
(color-theme-initialize)
(if (Xlaunch)
    (color-theme-gray30))

Which works but I get no color theme -- of course when the daemon
starts Xlaunch is false. Is there some way to say "do this if the
current client uses X"?

I was trying to get something like this working. To follow the 
discussion look at the thread "conditional font faces" from the 27th of 
February to 5th of March.

The only solution was to use a theme which uses similar colour schemes 
as no window to present a consistent environment in either and X window 
or the terminal.

GL and plz do post back if you find something that can actually switch 
between to themes without resorting to the above compromise.

Thanks to malsyned on #emacs I have the following that works like a charm:

I have tried something like that before, the problem with this is it
changes the theme for all the existing frames. So if I make an X
window frame, I get the proper theme. Then if I start a client in the
xterm, I get the proper theme for the no-window frame but my X window
frame also changes theme to that theme. It doesn't change back to the
desired X window theme even when I select the X window frame with the
mouse or Alt+Tab. It would be good if themes could be selected for
specific frames and not the entire emacs session itself.

If this is unrealisable for the current emacs release, could this be a
feature enhancement request for future releases?

Try using the code I posted. Do you think I would have said it worked like a
charm if it worked the way you describe?

I should have said, in addition to the hook you need

(setq color-theme-is-global nil)

Thank you thank you thank you! I have been scratching my head since I 
can obviously see it didn't work whereas you mentioned it did. With 
that, everything "Just Works".
