Hi,
I have noticed a problem recently in in the way packages
modify the load path. I am attaching what the load-path var looks
like in a freshly started emacs21. Please note that first in the path
come local lisp directories, as they should. Then come directories
added by add-on packages. Then come directories I have in /usr/local
-- then come the standard directories in /usr/share --- including the
directories of add-on packages, repeated!!
The glaring problem with this is that the add-on packages
(including my packages, gnus and vm) are violating emacs policy --
the /usr/local paths are supposed to have precedence over the paths
of standard emacs packages installed by Debian. However, the add-on
packages need to have their paths ahead of the standard paths -- so
the order ought to be
paths added by me --- /usr/local/ --- add-on packages -- standard
This way, if I wish, I can override even stand alone packages, if I
wish, by placing it in /usr/local (as I do with cvs versions of gnus,
bbdb, and tramp).
======================================================================
9) Emacs lisp load path.
At a minimum, each emacs has the following directories in the given
order in their load path:
/etc/<flavor>
/etc/emacs
/usr/local/share/emacs/<upstream>/site-lisp
/usr/local/share/emacs/site-lisp
/usr/share/emacs/<upstream>/site-lisp
/usr/share/emacs/site-lisp
======================================================================
The add-on packages ought to be using something like the
function contributed by Sam Hartman <[EMAIL PROTECTED]>, which is
also appended as an attachment below. This allows them to insert
their path into the load-path *after* the local paths, but before the
standard emacs paths.
Perhaps add-after-local (or a renamed version of the function)
should be provided by default, and policy changed to recommend the
use of that function.
I am copying this message to all packages currently violating
the emacsen policy on load-paths. Please consider this fair warning
for serious bugs to be filed when we reach a solution of this issue.
