ispell and flyspell

[wael-zwaiter]

Writing prose in texinfo, I wonder how best to use ispell and flyspell.  Should I
use both modes together or should I concentrate primarily on one rather than the
other?

I'd suggest to turn on flyspell-mode, it will highlight the spelling
mistakes as you type.

Re: ispell and flyspell

[wael-zwaiter]

Have written the following function, but (ispell-region) is failing.
How can I make option 2 call (ispell-region) on the current paragraph.

Basically, option 1 will check the current word, option 2 will check the current
paragraph, and option 3 will check the whole buffer.

(defvar spelt-state nil)
(defun spelt ()
  "Corrects the spelling of text."
  (interactive)

  (pcase spelt-state
    (1 (flyspell-mode 0)
       (ispell-word)
       (message "%s" "Spell: Word")
       (setq spelt-state 2))

    (2 (ispell-region)
       (message "%s" "Spell: Region")
       (setq spelt-state 3))

    (3 (ispell-buffer)
       (message "%s" "Spell: Buffer")
       (setq spelt-state 0))

    (_ (flyspell-mode)
       (setq spelt-state 1))) )

(global-unset-key (kbd "M-v"))
(global-set-key (kbd "M-v") 'spelt)

When you call a function, it is highly recommended to consult its doc
string, so you see what arguments it requires and what is the meaning
of each argument.  You _must_ supply the mandatory arguments, they
cannot be omitted when calling from Lisp.

I know, but aw unsure what commands to use for the arguments to get
the beginning and end of the paragraph.

"M-x apropos RET paragraph RET" is your friend.

In this case, I suggest using start-of-paragraph-text and
end-of-paragraph-text.

Re: ispell and flyspell

[wael-zwaiter]

Have now made this code.  Would start-of-paragraph-text and
end-of-paragraph-text work better?.

(defun spelt-paragraph ()
  (interactive)

  (let ((prg-bounds (bounds-of-thing-at-point 'paragraph)))
    (when prg-bounds
      (let ( (beg (point))
	      (end (cdr prg-bounds)))
	(ispell-region beg end)))))

AFAIR, it will do the same, just without extra level of indirection.

Re: ispell and flyspell

[wael-zwaiter]

I am having a problem with this variation

(defun spelt-paragr ()
  "TODO"
  (interactive)
  (ispell-region (start-of-paragraph-text) (end-of-paragraph-text)))

Did you read the doc strings of these functions?

Re: ispell and flyspell

[wael-zwaiter]

They do a move.  Which makes it not so clear why you suggested them.  I could
get the position using (point).  But I would need some assistance to complete
my function.

The usual paradigm is

   (save-excursion (start-of-paragraph-text) (point))

and the same with end-of-paragraph-text.

I like the use of save-excursion and see things quite straightforward.
