Using aspell in emacs

Using aspell in emacs

[henri-biard]

It is a very weird way of using ispell.



Anyway, thank you.  



Have used the Emacs Manual, but it does not say much about aspell except for a link.



What is the exact command?



(setq ispell-program-name "aspell")



or


(setq ispell-program-name "/usr/bin/aspell")


Tried to do C-h v ispell-program-name



and the command did not give me anything.

Change the variable `ispell-program-name' as it is a variable defined
in ‘ispell.el’ and you are done.

Its value is "/usr/bin/aspell"

You can customize this variable.

Program invoked by M-$ and M-x ispell-region commands.

Nothing is consistent when it comes to Unix and Emacs anyway,
or not everything is, I should say.

As a side note I have it

  ispell-program-name is a variable defined in ‘ispell.el’.
  Its value is "ispell" Original value was "/bin/aspell"

so if it is strange it is by default.

I know, but curiously enough, can you give an example of such
a manual?

It's (info "(emacs) Top") then I use C-s to search for "aspell" where
it says: These commands only work if a
spelling checker program, one of Hunspell, Aspell, Ispell or Enchant, is
installed.  These programs are not part of Emacs, but one of them is
usually installed on GNU/Linux and other free operating systems.  *Note
Aspell: (aspell)Top.

And I have never "set" the "aspell" program, that just works
automatically if you have oneof those spell checker programs.

Information is in Emacs manual: if you have some of those programs
installed it will work, there is nothing to do on your side.

I have verified it, if program `aspell' is on system, the variable
`ispell-program-name' will be set to its path. Finished there.

Most probably there is nothing to do on your side.

16.4 Checking and Correcting Spelling
=====================================

This section describes the commands to check the spelling of a single
word or of a portion of a buffer.  These commands only work if a
spelling checker program, one of Hunspell, Aspell, Ispell or Enchant, is
installed.  These programs are not part of Emacs, but one of them is
usually installed on GNU/Linux and other free operating systems.  *Note
Aspell: (aspell)Top.

What does it say?

"These commands only work if a spelling checker program, one of
Hunspell, Aspell, Ispell or Enchant, is installed."

Thus it says to me that command like M-x ispell is going to work if
you have those installed. 

Most probably you were using M-x ispell with aspell already.

Try reading manual.

OK, how does that happen one might wonder?

Check out:

  https://dataswamp.org/~incal/emacs-init/spell.el

A lot of that stuff, or all of it I think, are so basic ideas,
spell a word, spell words in different forms and with
different (common) interfaces, so that makes me think,

1) what of that is already implemented and

2) if it isn't, go ahead and use it (by my guest and improve
   it even more before you add it), since again, it is
   basic stuff.

For example this,

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

It spells the word WORD. That's right, I didn't have to take
LSD to come up with _that_ idea :) Is it in ispell already
only I failed to find it?

And if it isn't, why not? Useful not only for "us" but also
for ispell, internally, I'm sure!

Is the major mode a code mode? Interesting question, I know...

(defun is-code ()
  (member major-mode '(
                       c++-mode
                       c-mode
                       emacs-lisp-mode
                       prolog-mode
                       python-mode
                       sh-mode
                       Shell-script-mode
                       ) ; add more!
          ))

spell differently with the same command:

(defun spell (dict)
  "Spell with DICT.
\nIf a region, use `ispell-region'
\nIf editing code, `ispell-comments-and-strings'
\nIf writing a message, `ispell-message'
\nelse, `ispell-buffer'"
  (ispell-change-dictionary dict)
  (save-window-excursion
    (save-excursion
      (cond
       ((use-region-p) (ispell-region (region-beginning) (region-end)))
       ((is-message)   (ispell-message))
       ((is-code)      (ispell-comments-and-strings))
       (t              (ispell-buffer)) ))))

(PS, should the region stuff be optional beg and end
arguments, you think?)

aspell is supposed to be an improvement over ispell.  



On the gnu website, it is stated that Gnu Aspell is a spell checker designed to

replace Ispell.

Right, one spell-checker (which can do different things
depending on word, region, whole buffer etc) should be enough
IMO...

Hm, what does that mean? I installed zenity so got aspell?
What is zenity? "Zenity allows you to display GTK+ dialogs

It sounds like a method, to mark incorrect words on the fly
and offer an interface what to do with them.

But I personally don't like that as I don't like to get
interrupted when I type, I want to type all, then spell onee
(one and only one) time, and be done with it. So I can't help
you with flyspell but if you specify just a little bit ...
more! what your problem(s) are I'm sure many here that use it
will be able to help you...

Going more into it, it is as you say. It highlights incorrect words. It is good idea, 

but a poor implementation.  For instance, correction with flyspell has some serious

caveats.



It should have been assimilated into ispell and aspell.  aspell is supposed

to be an improved version of ispell.  I would like if emacs could implement

vertical selection in addition to icomplete, in ways similar to ivy.

C-h v ispell-program-name. Mine says:

,----

| Its value is "/usr/bin/aspell"
| 
|   You can customize this variable.

So if you have installed aspell and emacs can find it, it will use it automatically.
