The current version I have does not try to enforce a particular speller
- both ispell and aspell are supported. The choice is determined by the
setting of the customized variable `ispell-prefer-aspell' when both ispell
and aspell exist on the system.
I had used the function `exec-installed-p' which had it's roots in APEL
(A Portable Emacs Library). In digging deeper, it appears that this is
not necessary as the standard emacs function `executable-find' appears
to have the same desired functionality.
Here are the variables:
(defcustom ispell-prefer-aspell nil
"*Select preference between using the `ispell' or `aspell' program.
`ispell' is used by default.
When this variable is set, `aspell' is used if it is installed on the system."
:type 'boolean
:group 'ispell)
(defcustom ispell-program-name
(or (and (executable-find "aspell")
(or ispell-prefer-aspell
(not (executable-find "ispell")))
"aspell")
"ispell")
"Program invoked by \\[ispell-word] and \\[ispell-region] commands."
:type 'string
:group 'ispell)
I'm sure you'll argue to make `ispell-prefer-aspell' set by default ;-)
It is only used in the above location in the code.
I have several other patches, improvements to integrate into the current
version of ispell as well.
