emacsclient question: tty-setup-hook and X specific config

[Hadrien Lacour]

Hello,

I'm trying to convert my current .emacs config to work with
emacs --daemon/emacsclient. So far I've encountered two problems:

* The tty-hook-setup hook is run as it should (on `emacs -nw` and
`emacsclient -nw` invocations) but doesn't load my terminal specific file
after the first `emacsclient -nw` call.
$ emacs -nw myfile
$ emacs --daemon
$ emacsclient -nw -c myfile
$ emacsclient -nw -c myfile
The last line doesn't load st.el (attached).

* I want to apply theming only for graphical frames, but If I do:
$ emacs --daemon
$ emacsclient -nw -c myfile
$ emacsclient -c myfile
$ emacsclient -nw -c myfile

The theme is applied for the last two lines, even when using the -c option each
time.


The first one looks like a bug to me, and the second is just me not knowing how
to do that. Attached are my config file (~/.emacs) and my terminal file
(~/.emacs.d/lisp/term/st.el). Any idea about the why and how to fix it?

Terminal initialization file is loaded only once into a given session.
Why is it a problem in your case? The st.el file you show just
performs key bindings, why do you need to do that more than once?

$ emacs --daemon
$ emacsclient -nw -c myfile
$ emacsclient -c myfile
$ emacsclient -nw -c myfile

Not sure I understand why you thought -c had anything to do with theme
application. Anyway, if you want a theme to be applied only to GUI
frames, how about turning on the theme in the
after-make-frame-functions hook?

Well, for some reason, the keybinds are forgotten when this file isn't loaded.

If you can provide a recipe for reproducing this, please submit a bug
report with that recipe.

$ emacs --daemon
$ emacsclient -nw -c myfile (no theme)
$ emacsclient -c myfile (theme)
$ emacsclient -nw -c myfile (theme)
When I don't want the last line to have theming (because it is a tty session).
I thought that -c meant "new frame", and that the theme only applied to the
current frame, which is obviously wrong.

A theme is global. I don't think we have facilities for frame-local
themes.

So, is there way to do this? Do I need to reset the theme with
tty-setup-hook?

Not necessarily that hook, but some hook that is called when a frame
is created. I'd suggest after-make-frame-functions.

I wouldn't need all this if I could just make emacs work with st-256color,
though (it acts as if I only have 16).

You need to teach Emacs to recognize that, see xterm.el for how it is
done for xterm.
