I've been `abusing' Hunspell's feature with multiple dicts through
ispell.el. Beginning with 24.4., it stopped working and the issue
persists in 24.5. You can produce the error with:
1. Start emacs with
emacs --eval '(setq debug-on-error t)' -Q &
2. Eval:
(setq
ispell-local-dictionary-alist
'((nil "[A-Za-z]" "[^A-Za-z]" "[']" nil
("-d" "en_US")
nil iso-8859-1)
("deutsch8+american"
"[a-zA-Z\304\326\334\344\366\337\374]"
"[^a-zA-Z\304\326\334\344\366\337\374]" "[']" t
("-d" "de_DE,en_US")
nil iso-8859-1)))
(global-set-key "\C-cia"
'(lambda ()
(interactive)
(ispell-change-dictionary "deutsch8+american")))
3. Hit `C-c i a' followed by `M-x ispell RET' which says:
--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "ispell-phaf: No matching entry for
deutsch8+american.
")
signal(error ("ispell-phaf: No matching entry for deutsch8+american.\n"))
error("ispell-phaf: No matching entry for %s.\n" "deutsch8+american")
ispell-parse-hunspell-affix-file("deutsch8+american")
ispell-hunspell-fill-dictionary-entry("deutsch8+american")
ispell-start-process()
ispell-init-process()
ispell-buffer-local-words()
ispell-accept-buffer-local-defs()
ispell-region(1 610)
ispell-buffer()
ispell()
call-interactively(ispell record nil)
command-execute(ispell record)
execute-extended-command(nil "ispell")
call-interactively(execute-extended-command nil nil)

--8<---------------cut here---------------end--------------->8---
Eli kindly explained to me here
<http://thread.gmane.org/gmane.emacs.help/104130> that Hunspell does not
support multiple languages, but it looks like a bug in `ispell.el'.
Best, Arash

I've now modified ispell.el to support invocation of Hunspell with
multiple dictionaries. To see how it work, you will need to invoke an
additional command ispell-hunspell-add-multi-dic, before you attempt
to change the ispell dictionary to the form DICT1,DICT2,... This is
because ispell.el relies heavily on the assumption that any dictionary
admissible as argument to ispell-change-dictionary must be mentioned
in ispell-dictionary-alist or ispell-local-dictionary-alist. Since
it's impractical to add to ispell-dictionary-alist all the possible
combinations of all the installed dictionaries, I instead provided a
command to do that manually on the need-to basis.
Note that the argument to both ispell-change-dictionary and
ispell-hunspell-add-multi-dic _must_ be in the form of a list of
_existing_ dictionary names (or their aliases) separated by a comma.
That is, you cannot use something like "deutsch8+american", but should
use "de_DE,en_US" instead.
Initial testing indicates that using this feature works for
spell-checking text written in different languages, although the list
of the proposed corrections are sometimes incomplete. But I think
this is due to some problems in Hunspell itself, not in Emacs.
I'm closing this bug. Feel free to reopen if there are left-overs, or
file a new bug about whatever problems you still see.
