ispell single word

ispell single word

[Emanuel Berg]

How do I spell a single word, from Lisp, with
ispell? (Indeed, how do ispell with ispell...)

I just wrote this. It does seem to work but the
code looks - well, like something you are not
supposed to understand!

(require 'ispell)

(defun spell-one-word (word)
  (with-temp-buffer
    (save-excursion
      (insert word) )
    (condition-case nil
        (not (ispell-word))
      (error nil)
      )))
;; (spell-one-word "length") ; t
;; (spell-one-word "lenght") ; nil

But I guess I like it fine - so far.

Can you describe a use case where one needs to spell-check in Emacs a
word that is given as a string, and is not present in any buffer?
Because if the word is in some buffer, ispell-word, by default bound
to M-$, already does what you want.

The base use case is being able to ask Emacs,
is this the correct spelling of
a particular word?

One advanced use case can be in combination
with this string permutation code [1] - you can
feed a bunch of chars to it, get all possible
strings, then feed the strings to the checker
and thus filter out all possible words you can
form with the letters.

Type it and then invoke "M-$".

Boy, ispell really does stink it can't do this
programmatically. Well, at least mine can,
altho in an intricate, reversed way which
doesn't seem sound or natural.

It is a small wonder, in an ironic way, that
this isn't one of the first - if not *the*
first - building block around which the whole
software is made!

BTW who needs `+' to do addition in Lisp?
(+ 1 2 3) and such? When everyone knows it is
much more convenient to read the digits from
a buffer?
