During operation aspell creates two files; .aspell.en.pws,
.aspell.en.prepl ("en" is of course the language code). By default
these files are placed in ~/. You can control the location of
.aspell.en.pws by setting the ispell-personal-dictionary variable. But
you cannot control the location of .aspell.en.prepl.

So a new customization variable is needed to control the location of
.aspell.en.prepl. Perhaps named
ispell-personal-replacement-dictionary. It should be mapped to
aspell's --repl option which controls where the personal replacement
dictionary is stored.

Can't you customize ispell-extra-args?  In addition,
ispell-dictionary-alist supports language-specific options, AFAIK.

I didn't know about that variable and it's not in the manual afaics. I
managed to piece some elisp together using it to set the --repl
option. It works, though I don't think it is a very user-friendly
solution.

Why do you consider it not a user-friendly solution?  There's no limit
to command-line options a speller can have, so it is not reasonable
IMO to expect Emacs to have a separate variable for each one of them.
Thus, our solution to have a single variable that can hold any
additional options is a reasonable compromise.

As for its discoverability: in general, when you are faced with a
problem in some Emacs Lisp package, my advice is first to see whether
a solution already exists by browsing all the defcustom's of that
package (and its parent packages, if that is appropriate).  One way of
doing that is by using "M-x customize-group" bu giving it the group of
the package.

Stefan, WDYT?

I care little about what speller backend Emacs uses. I just want it to
follow the XDG (which I think it should do by default because dumping
dotfiles in ~/ is for neanderthals, but that's a different
story). Getting it to work was very difficult especially as I'm
often switching between languages. Here is part of my setup:

    (defun set-language (code name)
      (let* ((dir (expand-file-name "~/.config/aspell/"))
             (pd (concat dir code ".pws"))
             (rd (concat dir code ".prepl")))
        (make-directory dir t)
        (setq ispell-personal-dictionary pd)
        (setq ispell-extra-args (list "--repl" rd)))
      (ispell-change-dictionary code)
      (flyspell-buffer)
      (message (format "Switched to %s" name)))

    (setq flyspell-issue-message-flag nil)
    (add-hook 'text-mode-hook 'flyspell-mode)
    (add-hook 'flyspell-mode-hook
              (lambda ()
                (set-language "en" "English")))

I also have keybindings setup to quickly restart aspell because having
one buffer spell-checked in one language and another buffer in a
different language is not supported. I would be happier if I could
write:

    (setq ispell-personal-directory "~/.config/aspell")

and have ispell understand that it should dump all user configuration
files to that directory.

I could go either way with this one, to be really honest.  Eli is right
that proliferating our user options with all the details of concrete
spell checkers will start getting unwieldy at some point.

Personally, I'd rather see the interface of ispell.el get more
abstracted away from concrete spell checkers.  I don't think users of
Emacs shouldn't have to mess with aspell/ispell/hunspell/enchant (unless
they want to, of course).

So I'm not entirely sure that adding a new user option like this is
moving things in the right thing direction.
