bug#72604: 29.2; 29.2; when using customize to set ispell-program-name to ispell, ispell-library-diectory is set correctly, but not for aspell

[Uwe Brauer via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hi

Steps.

    - emacs -Q

    - describe-variable ispell-program-name: /usr/bin/aspell

    - describe-variable ispell-library-directory: nil

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

    - describe-variable ispell-library-directory: nil

    - customize-option ispell-program-name /usr/bin/aspell

    - describe-variable ispell-library-directory: nil

    - customize-option ispell-program-name /usr/bin/ispell

    - describe-variable ispell-library-directory: /usr/lib/ispell

Conclusion, customize-option sets ispell-library-diectory correctly if I
set ispell-program-name to ispell /usr/bin/ispell
but not if I set it to ispell /usr/bin/aspell

This is not really a bug, but a lack of a feature, no?

Regards

It is not a bug, no.  And it is not a missing feature, it is actually
the feature itself: when Apsell and Hunspell are installed correctly,
they don't need this variable to find their dictionaries.  I use
Hunspell, and the value of this variable in my Emacs is also nil,
although spell-checking works well in several languages.

So let me turn the table and ask you: why did you think this is a bug?

Because I cannot change the dictionaries, when using aspell:


I set ispell-program-name to  "/usr/bin/aspell"

I installed the aspell dictionaries for English, German, French and  Spanish.

However when I wanted to switch to the German dictionary, via
ispell-change-dictionary

no German dictionary was offered (but 65 different versions of English)

The ispell dictionaries are in /usr/lib/ispell
the aspell dictionaries seem to be in /usr/lib/aspell

But there is no aspell-change-dictionary.

So there seems a certain incoherence.

Does spell-checking with Aspell work outside of Emacs (from the shell
prompt)?  Or do you see the same error message about missing
dictionaries?

It works. Here is what I do.

    - create file test.org, with content
      Das ist waahr
      This is true (waahr is incorrect)

    - I run aspell -c -d de-1901 test.org

and the interface pops up suggesting to replace waahr by wahr, 
(among other suggestions)
wahr is the correct suggestion.

So yes aspell works but emacs does offer even this dictionary.this

I run a test again, I was not correct, ispell-change-dictionary offers dictionaries different from English, namely 

    1. spanish

    2. And french, including the swiss variant,

    3. But not German, also the german dictionary can be selected in the command line. Very strange indeed

And what does "aspell --help" show, when run from the shell prompt?

As suggested in
https://stackoverflow.com/questions/15346723/emacs-and-ispell-error-loading-german8
I had to run 

 sudo apt-get aspell-de

So it was not enough just to install the dictionaries.

Sorry for the noise.
