Re: How do *you* sync your zsh config files?

I have been in that situation in the past, though the number of different
zsh versions is now down to 3 (only 2 if you don't count 3.1.5, which I
only use part of the time at home) and the number of different OSs has
effectively dwindled to 2 (I now use Linux nearly everywhere, though the
distribution and libc vary).

The one-word answer is "ediff".  The three-word answer is "ediff and

The considerably more complicated answer is that I long ago added to the
top of my .zshenv the lines:

# Set variables sanely for assorted versions

case "$VERSION" in
# A several-way switch for various flavors of zsh

And then later on I have other case statements that switch on $HOSTTYPE
or whatever.  I also have several case statements on $VERSION in my
~/.zshrc file.  My init files probably produce approximately the same
interactive environment (modulo completely missing features in older
ones) in any zsh from 2.0 through 3.1.5, though it's been a long time
since I actually started up anything older than 2.3.

(The reason I assign VERSION from ZSH_NAME and ZSH_VERSION, rather than
the other way around, is because all my init scripts were first written
for the older versions of zsh that didn't have the ZSH_ parameters, and
I was too lazy to fix all the references.)

I also make a lot of use of autoloaded functions.  I haven't created a
new alias in years, except to prefix some function name with "noglob"
or some trick like that.  I've occasionally considered making $fpath be
operating-system-dependent, but I no longer use enough different OSs
to mess with it just now.

} I'm constantly finding that I've added an alias on one account and want to  
} use it on the others, but the machines are not such that I could make them  
} identical (at least two different $USERNAMEs, and on 2 of the machines I

I presume that $USERNAME is interesting because you're using some kind of
remote shell?

Set up a lookup table of usernames for yourself.  In 3.1.5, you can use an
associative array; in earlier versions, you can fake it.  Suppose you have
accounts on the machines "marble" "granite" and "shale".

    typeset -A usernames 2>&/dev/null
    # Have to do this in two steps because bad typeset options cause
    # the whole command line to abort in some versions of zsh
    [[ $? -eq 0 ]] || {

Now you can do stuff like this:

    rsh() {
	local command=rsh
	if [[ $OSTYPE:l == hp* ]]
	command $command -l ${usernames[$1]:-$USERNAME} "$@"

Of course, you may have to do more complicated things if the command wants
the host name to precede the -l option or whatever ...

} I once tried a 'zlocal' file that I would keep all my local configurations,  
} and keep everything else current, but that didn't work.

I used to do that with csh.  I agree that it doesn't work very well.

If you keep all your dot-files in a subdirectory (then either symlink to
them from your home dir or point ZDOTDIR at it), there's a package called
"remsync" that does a pretty good job of tracking changes to a directory
tree, allowing you to e-mail minimal changes back and forth.  But it's
not very good for merging -- for that you could pick a host where you do
have access to CVS, and use remsync to keep your other zdotdirs in sync
with with a sandbox (or possibly a couple of sandboxes) on that host.
