Subject: 25.2; ispell doesn't parse hunspell dictionaries properly
Date: Tue, 21 Feb 2017 10:18:57 +0100

Hello,

I have hunspell installed in the system with two default dictionaries.
I was trying to setup ispell so that it works properly and I couldn't.
So I started looking at the sources for ispell and I found one part that
can't work.  It may be intentional, but the real problem is that I can't
use spellchecker at all.  When `emacs -Q` is ran, it is enough to do M-$
with *no additinal settings*.  The error message (and following messages
for consecutive M-$) are visible below in 'Recent messages'.

I could only trace the problem to the ispell.el where the error is
printed.  The reason for that is probably the fact that `hunspell -D`
has this output on my system:

I tried various additional settings, setting the multi-dic for hunspell,
setting default dictionaries and nothing helped.  Can't ispell just
detect all the .aff files and then automatically use en_GB,cs_CZ as a
multi-dictionary for hunspell?  That's what I want anyway.

Let me know if I can provide any more information and thank you very
much in advance for looking into this issue.

Martin

P.S.: I seem to recall my previous configuration that made this working,
     but it was probably before lot of emacs and hunspell upgrades.
     The spellchecking is not working for some time for me, it's just
     now that I started looking into this issue.

P.P.S.: If I have (flyspell-mode) in a 'message-mode-hook and I start
       emacsclient with a file that automatically starts in
       message-mode, then emacs crashes due to the default dictionary
       being nil or something in that regard.

Please tell more details about the meaning of this.  Do you mean you
wanted to start Hunspell with 2 dictionaries so that it could
spell-check text that mixes 2 different languages?  Or did you mean
something else?  IOW, the "with two default dictionaries" part
confuses me.

I don't immediately see anything wrong here.  Does spell-checking work
if you set it up to use just one default dictionary, as usual?

Thanks.

Sorry, Idon't know spellcheckers that much.  Ilooked at hunspell's man
page, learned a bit, so I'll try to explain it better this time.

I have multiple dictionaries installed.  Hunspell finds all of them, but
selects *two* of them.  According to the man page, that is done
according to LC_ALL, LC_MESSAGES, and LANG environment variables.
Becuase hunspell selects more of them (which is something I want it to
do), it lists both of them as "LOADED DICTIONARY", ispell parses those
(actually just lines ending with ".aff") and if it finds more than one,
it errors out.

That's another problem.  Since the initialization itself fails, it
errors out before it checks any set variables.  So no matter what I set
up, it ends up with the same behaviour.  If I remove the second
dictionary from my system, however, it works.

I tried workaround with a wrapper around hunspell that modifies the
output of `hunspell -D` and it works, but that's really ugly.

Thank you,

What are the values of those environment variables?

The way to run Hunspell with more than one dictionary is hinted upon
in the doc string of the command ispell-hunspell-add-multi-dic.  After
you invoke that command and specify the dictionaries you want to use
(e.g., in your case "en_GB,cs_CZ"), type this:

  M-x ispell-change-dictionary RET en_GB,cs_CZ RET

Then try spell-checking.  It should work with that arrangement.  It is
possible that you will first need to modify your environment variables
to prevent Hunspell from loading more than one dictionary by default.

Honestly, I don't know where it takes the cs_CZ from, *but* if it
didn't, I would have to modify it so that it does.  Simply because
that's what I want it to do by default.

If I try

 M-x ispell-change-dictionary RET en_GB,cs_CZ RET

I get the same error.

M-x ispell-change-dictionary RET errors out with the same error.  If I
run it again, there are no dictionaries loaded, so I cannot use any
parameter for it except 'default'.

Why would I need to do that?  For me hunspell is working as I want it
to, exactly.

I honestly think that ispell should accept multiple dictionaries and
either behave like a multi-dic by default or just not error out when it
parses the second dictionary (less favourable option, though).  I would
love to add that functionality, but I'm not that familiar with the code,
unfortunately =(

Thanks,
Martin

Interesting.  What version of Hunspell is that?

Thanks.  I'll look into invoking ispell-hunspell-add-multi-dic
automatically when we find more than one dictionary loaded by
Hunspell, as it reports when invoked with the -D option.

Thank you.  Feel free too Cc me on any patch for that, I'll gladly test
it out (and learn more about the underlying code).

OK, thanks, will do.

Btw, do you have a DICTIONARY environment variable defined?  If yes,
what is its value?

Oh, I have, and it's (not surprisingly) "en_GB,cs_CZ".  I'm going to
find out where that comes from.

Please try the patch below.  (If it doesn't apply to your version of
ispell.el, tell me which version of Emacs you have, and I will try to
produce a compatible patch.)

TIA

Sorry I didn't get to this earlier.  One of the hunks didn't apply
correctly, so I used the file from master and it applied correctly.  So
with your patch applied on top of ispell.el from current master, the
situation is way better.  But I feel like it still doesn't work as
expected.  Not that anything would be broken, but it uses only the first
dictionary found.  I have to manually do:

 (ispell-hunspell-add-multi-dic "en_GB,cs_CZ")
 (ispell-change-dictionary "en_GB,cs_CZ")

I confirmed that both of them needed to be ran.  However after that
everything works perfectly.  So the only reason why I said it doesn't
work properly is that I see you running similar code in the patch:

  (when hunspell-multi-dict
    (ispell-hunspell-add-multi-dic hunspell-multi-dict)
    (setq ispell-current-dictionary hunspell-multi-dict))

When it works, I see hunspell is ran with '-d en_GB,cs_CZ', but it would
also work if hunspell was ran without '-d', but my guess is that you
don't want to do that.

Anyway, to find out a bit more, I did some debugging.  I'm not sure if
it helps or if it makes it more confusing, though.  Calling the function
returns "en_GB,cs_CZ".  When I add some prin1 statements around the
'add-multi-dic' and 'setq' I see it is called before the hunspell is ran
and it has the proper values set.  However when I check the values from
the scratch buffer after it was ran (either manually or by
spell-checking a word), it's like it didn't do anything.  It behaves
like it did all the right things, but in a different scope, even though
the variables are not buffer-local or anything.

Unsure how to continue or debug this more, I am giving up for today.
Let me know if I should debug it a bit more somehow.

Have a nice day,
Martin

Now it's my turn to apologize for the delay...

You are right, that was the wrong direction to try to solve the
problem.

Here's another attempt.  It should be applied _instead_ of the
previous patch, to the original version of ispell.el.  Let me know if
it works OK for you.

Thanks.

No further comments, so I pushed the proposed changes, and I'm marking
this bug done.

Thanks for the feedback.
