Short:
I want to be able to set buffer that will be displayed in window of newly
created frame.
I need it for my emacs package, that will save and restore some emacs state
including
last window configurations, opened and displayed buffers and such.
I tried this: add hook to `after-make-frame-functions'. Inside this hook I
do
`(switch-to-buffer <some-buffer>)' and frame is switched to that
<some-buffer> at first,
but after a short time it's switched to *scratch*.
The one way I found how to overcome this behaviour is by setting the
`initial-buffer-choice' in the `after-make-frame-functions' hook. One
drawback of this
approach is that it could only be set to name of file, t or nil and so
there is no way to
force switching to buffer without underlying file. This could be fixed int
server.el:1258
replacing
(unless (or files commands)
(if (stringp initial-buffer-choice)
(find-file initial-buffer-choice)
(switch-to-buffer (get-buffer-create "*scratch*")
'norecord)))
to
(unless (or files commands)
(switch-to-buffer
(get-buffer-create
(or (cond
((stringp initial-buffer-choice) (find-file-noselect
initial-buffer-choice))
((functionp initial-buffer-choice) (funcall
initial-buffer-choice)))
"*scratch*"))
'norecord))
and modified defcustom in in startup.el:41 would be:
(defcustom initial-buffer-choice nil
"Buffer to show after starting Emacs.
If the value is nil and `inhibit-startup-screen' is nil, show the
startup screen. If the value is a string, visit the specified file
or directory using `find-file'. If t, open the `*scratch*'
buffer. If function, switch to a buffer returned by this function.
A string value also causes emacsclient to open the specified file
or directory when no target file is specified."
:type '(choice
(const :tag "Startup screen" nil)
(directory :tag "Directory" :value "~/")
(file :tag "File" :value "~/.emacs")
(function :tag "Function")
(const :tag "Lisp scratch buffer" t))
:version "23.1"
:group 'initialization)
This code allows setting `initial-buffer-choice' to a function returning
needed buffer.
