;; -----------------
|
|
|
|
|
;; Variables `desktop-buffer-mode-handlers' and `desktop-minor-mode-handlers'
|
|
|
|
|
;; are supplied to handle special major and minor modes respectively.
|
|
|
|
|
;; `desktop-buffer-mode-handlers' is an alist of major mode specific functions
|
|
|
|
|
;; to restore a desktop buffer. Elements must have the form
|
|

|
|
;;
|
|
|
|
|
;; (MAJOR-MODE . RESTORE-BUFFER-FUNCTION).

|
|
|

;; evaluates the desktop file. Buffers with a major mode not specified here,
|
|
|
|
|
;; are restored by the default handler `desktop-restore-file-buffer'.
|
|
|
|
|
;; `desktop-minor-mode-handlers' is an alist of functions to restore
|
|
|
|
|
;; non-standard minor modes. Elements must have the form

;;
|

|
|
|
|
|
;; Minor modes not specified here, are restored by the standard minor mode
|
|
|
|
|
;; function. If you write a module that defines a major or minor mode that
|
|
|
|
|
;; needs a special handler, then place code like
|
|
|
|
|
|
|
|
|
|
;; (defun foo-restore-desktop-buffer
|
|
|
|
|
;; ...

|
|

|
|

;; ...
|

|
|
|
|
|
;; '(bar-mode . bar-desktop-restore))
|
|
|
|
|
|
|
|
|
|
;; in the module itself, and make shure that the mode function is
|
|
|
|
|
;; autoloaded. See the docstrings of `desktop-buffer-mode-handlers' and
|
|
|
|
|
;; `desktop-minor-mode-handlers' for more info.
|
|
|
|
|
|
|
|
|
|
;; Minor modes.
|
|
|
|
|
;; ------------
|
|
|
|
|
;; Conventional minor modes (see node "Minor Mode Conventions" in the elisp
|
|
|
|
|
;; manual) are handled in the following way:
|
|
|
|
|
;; When `desktop-save' saves the state of a buffer to the desktop file, it
|
|
|
|
|
;; saves as `desktop-minor-modes' the list of names of those variables in
|
|
|
|
|
;; `minor-mode-alist' that have a non-nil value.
|
|
|
|
|
;; When `desktop-create' restores the buffer, each of the symbols in
|
|
|
|
|
;; `desktop-minor-modes' is called as function with parameter 1.
|
|
|
|
|
;; The variables `desktop-minor-mode-table' and `desktop-minor-mode-handlers'
|
|
|
|
|
;; are used to handle non-conventional minor modes. `desktop-save' uses
|
|
|
|
|
;; `desktop-minor-mode-table' to map minor mode variables to minor mode
|
|
|
|
|
;; functions before writing `desktop-minor-modes'. If a minor mode has a
|
|
|
|
|
;; variable name that is different form its function name, an entry
|
|
|
|
|
|
|
|
|
|
;; (NAME RESTORE-FUNCTION)
|
|
|
|
|
|
|
|
|
|
;; should be added to `desktop-minor-mode-table'. If a minor mode should not
|
|
|
|
|
;; be restored, RESTORE-FUNCTION should be set to nil. `desktop-create' uses
|
|
|
|
|
;; `desktop-minor-mode-handlers' to lookup minor modes that needs a restore
|
|
|
|
|
;; function different from the usual minor mode function.
