Hello.  I reported Emacs bug#42248 and I and the Emacs developers
realized at least part of the problem is with Guix version of Enchant.

On an updated Debian bullseye, enchant 2.2.8 from Guix misreports
numerals.  The same enchant upstream version, when installed from APT,
does not have this problem.  Guix enchant 2.2.8 on Debian buster also
misreports numerals.

See (on Debian bullseye):

$ enchant-2 -v
@(#) International Ispell Version 3.1.20 (but really Enchant 2.2.8)
$ which enchant-2
/usr/bin/enchant-2
$ enchant-2 -l -d en_US /tmp/enchant-test.txt
Doesn
Amarelou

$ guix install enchant; hash enchant-2
[...]
$ enchant-2 -v
@(#) International Ispell Version 3.1.20 (but really Enchant 2.2.8)
$ which enchant-2
/home/jorge/.guix-profile/bin/enchant-2
$ enchant-2 -l -d en_US /tmp/enchant-test.txt
2015
Casa
42
Amarelou
2018

The file /tmp/enchant-test.txt:
--8<---------------cut here---------------start------------->8---
Doesn't 2015
Casa 42
Amarelou 2018
--8<---------------cut here---------------end--------------->8---

So enchant 2.2.8 (either from APT or from Guix) does not understand
"doesn't"; and, what's worse, enchant-2.2.8 from Guix reports every
numeral as a misspelling.

Regards

I now reread my experiment and realized enchant from Guix does
understand "doesn't".  So enchant 2.2.8 from Guix gets "doesn't"
correctly, but not numerals, and enchant 2.2.8 from APT gets numerals
correctly, but not "doesn't".  Could enchant get both numerals and
"doesn't" correctly?  That would be ideal.  Failing that, APT's enchant
situation is much preferable than Guix's enchant.

So I've look at it quickly. It seems our enchant is built only with aspell, whereas debian is built with hunspell. In fact, our hunspell is able to detect the misspellings, and does not flag numbers nor doesn't. Maybe you could use hunspell directly as your enchant? Not sure if that works, I'm not an emacs user.

I've tried building enchant with hunspell, but although it worked, it still doesn't use the hunspell dictionnary. Looking at strace, it ignores $DICPATH which hunspell uses, and looks in various other directories. Sxmlinking one of them to $DICPATH didn't work either. Enchant was able to find hunspell's en_US.dic file, but then fails when looking for en_US.aff in the same directory. What is this aff file?

Hi,

I ended up pushing two patches: the first one installs the required .aff files along with the .dic files in hunspell-dict-en. The second adds hunspell as an input to enchant.

With these, on Guix System, I was able to reproduce the behavior of debian's enchant. Numerals are not marked as incorrect anymore.

I have two issues left: enchant ignores DICPATH and loads dictionaries from global directories, which is an issue on the Guix System (less so on foreign distros as they probably have dictionaries installed at these locations).

Hunspell itself doesn't flag "doesn" as incorrect, whereas enchant does, despite using the same dictionary. If this is also the case on Debian, we might have found a bug in enchant.

So: after you run guix pull and update enchant, you will see the same behavior from guix' and debian's enchant.

Emacs does support several other spell checkers, but I want to use
enchant in order to share the user dictionary with other applications
that use enchant.

Yes, same here.  Thank you!

The command-line tool enchant-2 misreports "doesn't", but Gedit, which
very probably uses Enchant, correctly accepts "doesn't and four other
contractions I tested.  It seems Gedit calls the enchant library in a
different way than Enchant's own command-line tool.

The reason to believe that Gedit uses Enchant are:
1. Wikipedia says so
2. Gedit's spell checker correctly accepts every word I have in the
   Enchant user dictionary.

Best regards
