Replacing gnus package with pgnus

Replacing gnus package with pgnus

[Jake Colman]

I just installed Xemacs 21.1 and wish to replace the production gnus shipped
with XEmacs with the current version of pgnus.  How do I replace a package
that ships with XEmacs with a newer version of that package?  I need to do
this locally so that only I see the superceded package; other users should
continue to see the original package.

Thanx!

The simplest way to do this is the undocumented way.  Note to FSF Emacs
users: this only works for XEmacs 20.4+.

    mkdir -p ~/.xemacs/lisp
    ln -s /path/to/gnus/lisp ~/.xemacs/lisp/pgnus

That's it!  No need to change anything in your .emacs file.

If you want to also have the etc package set up correctly, do this:

    mkdir -p ~/.xemacs/etc
    for f in `echo /path/to/gnus/etc/*`
    do
      ln -s $f ~/.xemacs/etc
    done

However, that is a system-wide change. He only wants this to apply to
himself. In that case, install it wherever (somewhere in your homedir is
good) and add this to your ~/.emacs:

(setq load-path (cons (expand-file-name "~/share/emacs/site-lisp/")
load-path))

If PGnus is installed somewhere besides ~/share/emacs/site-lisp/, put the
different path in place of it.

        Just for information, another undocumented (I think) feature is the
`site-packages' directory: if you put something under this directory, it will
take precedence over what's in `xemacs-packages'.

        There are reasons why this is not documented though. The location and
the structure of these directories is probably going to change someday, mainly
because of Mule. Also, note that currently, ~/.xemacs/packages is a potential
place for putting personal packages, but will change to ~/.xemacs in a near
future.

What do you mean, system-wide?  He added a symlink in ~/.xemacs/lisp,
how can that be system-wide?

It's the other way around.  Right now, ~/.xemacs is on the
package-path, isn't it?

Whoops. I mis-read Colin's mail as meaning he should link his install to
where the system-wide install was; I read the syntax for ln -s backwards.

        You're right. So the future has come faster than I'd expected :-)

This is not undocumented at all, c.f. README.package and the "Startup
Paths" info sections. It might be documented better though.

Huh, what's Mule got to with it?

        Please refer to the (rather violent) discussion I had with Michael
Sperber a long time ago about the packages directory names and places. I'm not
sure I want to re-start this debate here, but in short: if you have
xemacs-packages/ (std distrib), site-packages/ (site specific) and
mule-packages/ (std mule), what if somebody wants (or writes) a site specific
mule package ?
