Font setting for runemacs and frame

Font setting for runemacs and frame

[Shuguang Sun]

The following message is a courtesy copy of an article
that has been posted to gmane.emacs.help as well.

Hi,

I have some font setting in my dot emacs, however, it doesn't work
unless after some frame action.

My font setting
```
(cl-pushnew '(w32 (font . "Consolas-16")
                  (fullscreen . maximized))
            window-system-default-frame-alist)

(defun frame-setting (&optional frame)
  (when (display-graphic-p)
    (message "display-graphic-p"))
  (message "frame-setting call")
  (let ((frame (or frame (selected-frame))))
    (message "frame: %s" frame)
    (if (string-equal system-type "windows-nt")
     (dolist (charset '(kana han cjk-misc bopomofo chinese-gbk gb18030))
          (set-fontset-font nil charset
                              (font-spec :family "Microsoft Yahei")
                              frame 'prepend)))))

;; set the font after make frame
(add-hook 'after-make-frame-functions #'frame-setting)
```

And some hooks in after-init-hook
```
(if (not (daemonp))
    (progn
      (message "frame-setting in non-daemon")
      (frame-setting)))
```

The function-setting actually is called.

In case of
```
emacsclientw.exe --alternate-editor= -n -e "(raise-frame )"
```
it messages: frame-setting call

However the font setting make no effect in case of simply run
runemacs.exe, it messages:

frame-setting in non-daemon
display-graphic-p
frame-setting call
frame: #<frame emacs@RSHMX11052 00000000037b6e90>


Is it due to the window-system-default-frame-alist which might flush all
the font setting?

For runemacs, why don't you just use default-frame-alist?

I use window-system-default-frame-alist trying to manage one dot.emacs
for both windows box and linux. It seems both default-frame-alist and
window-system-default-frame-alist will flush the font setting.

I need set different font according to the fontset, and it seems neither
default-frame-alist nor window-system-default-frame-alist is able to
make it.

Sorry, I don't think I follow: what do you mean by "flush"?  Can you
show what you tried with default-frame-alist, and describe the
effects?

Fontsets are the way to customize fonts more flexibly, so I don't
think I understand what you mean by "different font according to the
fontset".  Again, showing what you do or tried but didn't work, will
help remove any misunderstanding.

I'm asking all these questions because it sounds like you
unnecessarily use very complicated means, where much simpler means
exist that should allow you to do what you want.

(cl-pushnew '(w32 (font . "Consolas-16"))
            window-system-default-frame-alist)

or 

(add-to-list 'default-frame-alist '(font . "Consolas-16"))

To set the default font as Consolas-16 in w32 system.

To specify font for fontset, cjk etc., I use the code below and actually
make it a function and call it in after-make-frame-functions (new frame
in daemon mode) or call it after-init-hook (intended for runemacs with
`if (not (daemonp))`).

(dolist (charset '(kana han cjk-misc bopomofo chinese-gbk gb18030))
  (set-fontset-font nil charset
                    (font-spec :family "Microsoft Yahei")
                    nil 'prepend))

However with the setting of window-system-default-frame-alist or
default-frame-alist above, it takes no effect until I make a new frame
(after-make-frame-functions). Emacs takes font for the fontsets above
according to Windows font fallbacks, e.g., MS Gothic.


Finally, I find that if I put `(set-frame-font "Consolas-16" nil t)` in
my dot.emacs, the font setting for above fontsets works in runemacs case
without additional frame make action.

This will only work for frames other than the first frame.

Why do you need to call this in a hook?  Why not just at top level of
your .emacs file?

This is documented behavior: to modify the looks ofg the first frame,
you need to set initial-frame-alist in addition to
default-frame-alist.

Years ago, it didn't work for server or daemon, and I tried the hook way.
Now it seems to work well.

The docstring for 'initial-frame-alist' says:

    Parameters specified here supersede the values given in
    `default-frame-alist'.

which certainly reads to me like 'configure only default-frame-alist
if you want all frames including the initial one to be identical'.

Oops, I stand corrected.  I guess the problem was that the alist was
set in a hook rather than directly.

I donʼt know. I haven't tested initial-frame-alist vs
default-frame-alist, perhaps the docstring is wrong.

The docstring is correct: default-frame-alist applies to the initial
frame in the absence of an initial-frame-alist setting (in normal
startup mode, Iʼve not tested daemon mode).

Sorry for wrong information in last message. Actually the font setting
code above doesn't work in daemon.

runemacs --daemon
OR
 ./emacsclientw.exe --alternate-editor= -n -e "(raise-frame )" &

Then a popup window with:

Please submit a bug report about this with all the relevant
information, especially your font customizations.  Preferably, please
include with the bug report a minimal .emacs file that still
reproduces the problem for you.

> Reading symbols from /c/Users/suns18/emacs/bin/emacsclientw...done.

You've attached GDB to the wrong process: the problem happens in
Emacs, not in emacsclientw.

Also, why did you end your emacsclientw command with a "&"?  This is a
Unix thing, not a Windows thing.  Which shell are you using, and how
does it interpret the trailing "&"?
