Hello,
Trying to provide batch Emacs/Org scripts to colleagues, I must ensure that
they have Org 8.
I wrote the following code so that users which have a default (Cygwin) Emacs
24.3.1 (with the default Org 7.9.3f) are proposed an upgrade through the
`package' manager:
--8<---------------cut here---------------start------------->8---
(require 'package)
(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/"))
(package-initialize)
;; version info
(let ((org-dir (file-name-directory (locate-library "org"))))
(message "Org mode version %s (org @ %s)" (org-version) org-dir))
(unless (string-match "^8" (org-version))
(message "This version of Org mode is no longer supported")
(if (yes-or-no-p (format "Install package `%s'? " 'org))
(ignore-errors
(package-install 'org))
(setq debug-on-error nil)
(error "Please upgrade to 8 or later")))
--8<---------------cut here---------------end--------------->8---
Problem experienced by colleagues: "Invalid function:
org-with-silent-modifications".
Looking on the web, I find a post [1] where Bastien tells:
When installing from ELPA, please do so from a fresh Emacs session where no
Org function has been called.
That wasn't the case in the above code, as I first had to call `org-version' to
check for their current version, then install from ELPA if they don't have an
Org 8...
So,
- Is there a way to unload Org before installing from ELPA? (= workaround)
or better:
- Is there a way to fix the problem? (= solution)
Best regards,
Seb
