Create a complete/huge dictionary for aspell.

Create a complete/huge dictionary for aspell.

[Hongyi Zhao]

On Ubuntu 20.04, I'm using aspell as the ispell checker program, which
can be confirmed with `C-h v ispell-program-name RET' as shown below:

;;;
ispell-program-name is a variable defined in ‘ispell.el’.

Its value is "/usr/bin/aspell"
;;;

I found that too many words are not included in the pre-established
aspell-en dictionary, say this one: destigmatize [1]:

$ aspell dump master | egrep -i destigmatize
$

For additional information about the packages installed on my
computer, see the following:

$ aspell --version
@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.8)
$ dpkg --get-selections |grep ^aspell
aspell                        install
aspell-en                    install

So, I want to make a complete/huge dictionary for aspell, say, based
on the well known Webster's unabridged dictionary of the English
language.

Any hints for achieving this aim?

I installed the above dictionary, but still can't see the completion
hints for the word "destigmatize" in the candidate list. See the
attachment for more details.

I've browsed through this configuration, but found nothing related to
iamerican-Insane dictionary.

Yeah, but when it comes, and is correct after you carefully
examine and double-check the word, hit I so it will be in your
local list forever after. That's how it works, you'll still
have to do that for a lot of words in the beginning. But add,
add and add and soon enough that will almost never happen.

I've posted a similar issue [1]. Here I give my some further tries and
testings as described below.

I've created a [personal
dictionary](http://aspell.net/man-html/Format-of-the-Personal-and-Replacement-Dictionaries.html)
which has the following contents:

```
$ cat ~/.aspell.en.pws
personal_ws-1.1 en 2
Telegram
destigmatize
```
This time, the expected word really appread in the correct ispell's
popup dropdown menu, as shown in the attachment. But I still can't
understand the following question: since I've added the correct rarely
used word to the personal dictionary, why we still need the
installation of the big/huge/insane dictionaries, such as
iamerican-insane?

Additional comment: The screenshot was prepared by the following
command, which allows some delay so that I've enough time to show the
popup dropdown menu:

$ scrot -c -d 5 -s -b

Uhm, I'm not sure I follow, probably not, right?

But basically you want the iamerican-insane to get everything
you can as easily as possible, the rest I don't know any other
way than to add them one by one by using them and then, with
the the ispell interface in Emacs, have them end up in you
local dictionary, to complement any "insanity" left out that
you feel you have it inside you to contribute...

A good idea actually with one little issue, why are everyone
expected to do this all the time and over and over? every year
every person "insane" should send their locals upstream to
level up insanity at headquarters, so we can even easier get an
even bigger list.

I think that actually, because of proximity in time, space,
and interests/hobbies/activities (computers) it is possible
the very same words are being added from that world over
and over!

Or does something actually happen with all that "silent
feedback"?

PS. Can you believe any other software get that much active
    feedback, and then never care about it? So I hope that
    isn't what happens but I sure never agreed anywhere they
    could use mine so I guess it doesn't!

Donʼt you also have to select the dictionary to use either with the
function ‘ispell-change-dictionary’ or by setting
‘ispell-local-dictionary’ (global default is configured via
‘ispell-dictionary’)?  Or does the “insane” dictionary become aspellʼs
default once installed?

Both ‘ispell-local-dictionary’ and ‘ispell-dictionary’ are nil on my side:
;;;
ispell-local-dictionary is a buffer-local variable defined in
ispell.el.gz.

Global Value
nil
;;;

;;;
ispell-dictionary is a variable defined in ispell.el.gz.

Value
nil
;;;

But, I don't know which one is corresponding to iamerican-insane dictionary:

$ aspell dump dicts
en
en-variant_0
en-variant_1
en-variant_2
en-w_accents
en-wo_accents

Now I start to think it doesn't work for me either!

I did

  $ sudo apt-get --install-suggests install iamerican-insane
  $ sudo select-default-ispell

and selected american-insane (the UI even mentions Emacs BTW)

but the dictionary wouldn't turn up with

  M-x ispell-change-dictionary RET SPC

then I did

  $ sudo apt-get --install-suggests install iamerican-\*

and it installed all of it, I did 'ispell-change-dictionary'
again and all the smaller alternatives were now there, but
I picked -insane anyway, and what happened is, now "american"
turns up as an alternative in Emacs.

Is this as it should be, i.e. I use the -insane version and it
is solved under the hood somehow? Or am I using
just iamerican?

As you can see, there are so many dictionaries, and I don't know which
of them is/are corresponding to iamerican-insane dictionary.

Maybe I don't understand the nature of my question and what exactly is
the problem I’m trying to solve. The discussion on here [1] makes me
realize the essence of some relevant problems more clearly, so I refer
it back to you here, just FYI.

Emacs defaults to using aspell for spell-checking.  The package
“iamerican-insane” installs a dictionary for the ispell program.  Both
programs use different, incompatible formats for their dictionaries.  If you
set ‘ispell-program-name’ to “ispell”, Emacs will offer the installed ispell
dictionaries with “M-x ispell-change-dictionary”.  Note, though, that you
also *cannot* share your personal dictionary between these two programs.

You may generate an american-insane dictionary for aspell from the wordlist
distributed in the package “wamerican-insane” using:

    aspell --lang=en --encoding=utf-8 \
        create master /usr/lib/aspell/en_US-insane.rws \
        </usr/share/dict/american-english-insane

I also had to create a file “/usr/lib/aspell/en_US-insane.multi” with the
following content for the dictionary to be picked up by aspell:

    add en_US-insane.rws

Afterwards check whether “en_US-insane” is listed in the output of
“aspell dicts”.  If it is, it should also be selectable in Emacs with
“M-x ispell-change-dictionary” (when ‘ispell-program-name’ is “aspell”).

As an aside: at a quick glance, I think that the insane dictionary contains
some dubious spelling.

I could not reproduce that.

I donʼt know how to directly see which dictionary is used.  Try looking at
the [ia]spell processʼ arguments, either in emacs with “list-processes” or
in the shell with “ps”.  In the shell, you may also look at a list of open
files of the [ia]spell process using “lsof -p IASPELL_PID”.

Debian does some Debian things under the hood to make the installed
dictionaries selectable in Emacs.  They also ship custom versions of
“ispell.el” and “flyspell.el”.  Check the package “dictionaries-common”.

`ispell-program-name' is "ispell".

As described in the previous post, Debian seems to react upon
the installation of the iamerican-insane package as with the
superuser script to set the dictionary that alternative does
show up. However after that with `ispell-change-dictionary' the
alternatives are still only

  american
  default
  svenska

If I remove all iamerican-* packages the american alternative
go away. I don't know if this is related to the iamerican
package in particular but that seems reasonable.

But then why aren't the iamerican-small, iamerican-large,
iamerican-huge, and iamerican-insane there whenever _they_
are installed?

PS. The Swedish dictionary doesn't work either. It says
    "ispell-init-process: Illegal format hash table
    /usr/lib/ispell/svenska.hash - expected magic2 0x9602, got

The iamerican packages call in their postinst script [1]
“update-default-ispell” which will call the function
“build_emacsen_support”; this function creates the file
</var/cache/dictionaries-common/emacsen-ispell-dicts.el>
with entries for ‘ispell-dictionary-alist’ (indirectly,
see the function ‘debian-ispell-initialize-dicts-alist’
and the hook ‘ispell-initialize-spellchecker-hook’).

> However after that with `ispell-change-dictionary' the

>   svenska

“emacsen-ispell-dicts.el” is only read at start-up [2].  If you install a
new dictionary, an already running Emacs will not know about it.  You may
try to reinitialise the dictionary with the following snippet:

    (progn
      (setq debian-ispell-only-dictionary-alist nil
    	debian-aspell-only-dictionary-alist nil
    	debian-hunspell-only-dictionary-alist nil
    	ispell-dictionary-alist nil)
      (load-file "/var/cache/dictionaries-common/emacsen-ispell-dicts.el")
      ;; There is a setter associated with ‘ispell-program-name’ which
      ;; calls ‘ispell-set-spellchecker-params’.  Calling this function
      ;; directly does not work; I donʼt understand why.
      (setq ispell-program-name "ispell"))

For testing purposes, start Emacs with the “-q” (“--no-init-file”)
switch.  Do the dictionaries show up then in the dialog of
‘ispell-change-dictionary’?  Do you use a custom built Emacs or the
Debian package?

> If I remove all iamerican-* packages the american alternative

It is connected to the action of removing the dictionary: ispell filters
the list of ‘ispell-dictionary-alist’ for the dialog: it will only
display those entries whose dictionary files exist.

> But then why aren't the iamerican-small, iamerican-large,
> iamerican-huge, and iamerican-insane there whenever _they_

To reiterate: their entries are added on installation of the respective
package to the file emacsen-ispell-dicts.el; this file is only loaded at
start-up.

Does not work for me either.  Seems like a bug.  Please report it.
Meanwhile, try recreating the .hash file manually (requires the wswedish
package):

    buildhash /usr/share/dict/svenska /usr/lib/ispell/svenska.aff \
        /usr/lib/ispell/svenska.hash


Footnotes:
[1]  If you have the package installed you may read their content here:
     </var/lib/dpkg/info/iamerican.postinst>.  Otherwise, download the
     package and open it: the file is in the subarchive

That file,
/var/cache/dictionaries-common/emacsen-ispell-dicts.el, has as
its last line

  (setq debian-hunspell-dictionary (debian-ispell-get-hunspell-default))

but the function "debian-ispell-get-hunspell-default"
is undefined.

Anyway same.

A lot of dictionaries show up with -q! No idea why, and
interestingly, american-insane and the other installed do not.

It is installed from source!

That works! Cool!

A bug where, in Debian's wswedish?

I wonder why people still insist on using ispell (the program), when
hunspell and aspell are widely available, provide better
spell-checking in more languages, and detect the installed
dictionaries automatically instead of requiring complicated manual
sertup?

This means that the Debian specific initialisation is not run: the Debian
Emacs package installs a custom “startup.el” file that loads
“debian-startup” [1], which loads the Debian specific configuration; this is
why the function ‘debian-ispell-get-hunspell-default’ is not defined.  If
you want to use the Debian dictionary configuration, you may try to load the
necessary code manually:

    (progn
      (load-file "/usr/share/dictionaries-common/site-elisp/debian-ispell.el")
      (load-file "/var/cache/dictionaries-common/emacsen-ispell-dicts.el")
      (setq ispell-program-name "ispell") ; [2]
      )

I donʼt think you can load all the Debian start-up files, if you have
installed Emacs below /usr/local/: I suspect ‘debian-pkg-add-load-path-item’
[3] will not be able to add Debian specific paths to ‘load-path’ at the
correct position.  There may be other issues as well.

Another solution, maybe more appropriate for a custom installation, could be
to add the dictionaries you are interested in, and that are not already in
‘ispell-dictionary-base-alist’, manually to ‘ispell-local-dictionary-alist’.
Copy the necessary information from emacsen-ispell-dicts.el [4] (or extract
it manually or programmatically from the pertinent files in
/var/lib/dictionaries-common/ispell/):

    (setq ispell-local-dictionary-alist
          '(("american-large"
             "[A-Za-z]"
             "[^A-Za-z]"
             "[']"
             nil
             ("-B" "-d" "american-large")
             nil
             utf-8)))

The broken hash file belongs to the “iswedish” package.  Therefore, I
would file the bug report against “iswedish”.  (Incidentally, both
“wswedish” and “iswedish” are actually built from the same Debian source
package.)

[2]  This forces ‘ispell-set-spellchecker-params’ to run and sets
     ‘ispell-dictionary-alist’ appropriately.
