Subject: 28.2; ispell personal dictionary location for hunspell engine
Date: Mon, 30 Jan 2023 19:53:19 -0500

[Message part 1 (text/plain, inline)]

The ispell package in Emacs is not using the user-specified location of
the personal dictionary for hunspell.

In particular, neither of these two settings are being respected:

(setq ispell-personal-directory "/c/Users/xxxx/.hunspell_en_US")
(setq ispell-cmd-args "-p /c/Users/xxxx/.hunspell_en_US")

Instead, it appears that ispell is hardwired to use the file
%USERPROFILE%hunspell_en_US regardless of whether or not the user has
specified another choice for their personal dictionary.

Note that a file named %USERPROFILE%hunspell_en_US is being created at
the save prompt when adding a new spelling regardless of whether or not
a file named .hunspell_en_US already exists in the user's home directory
(the default file path for a personal directory) and that the Windows
macro %USERPROFILE% is not being properly expanded either (so it becomes
part of the dictionary name in unexpanded form).

Hunspell is the latest version (1.7.2) installed from the MINGW64 repository
in the MYSYS2 project.  It is otherwise working just fine with Emacs
using the following two settings:

(setq ispell-program-name "hunspell")
(setq ispell-local-dictionary "en_US")

Note that the HOME variable is set in my Emacs init file and points
to C:/Users/xxxx/

These are incorrect settings: the native Windows build of Emacs
doesn't understand the MSYS /c/foo/bar notation.  Please use the
native Windows format "c:/Users/xxx/" or "C:\\Users\\xxx\\" instead
(both should work, but backslashes need to be escaped in Emacs
strings).

Does it work for you as expected if you invoke Hunspell from the shell
prompt like this:

  hunspell -d en_US -p c:/Users/xxx/.hunspell_en_US SOME-FILE

(which starts Hunspell with its own text-mode user interface), and
then use the 'i' command inside Hunspell to save some words in the
personal dictionary?  (I presume that your Hunspell supports the
interactive invocation like above.)  If that doesn't save in the
correct file either, then it's a Hunspell bug, and you should report
it to the folks who develop Hunspell or those who produced the Windows
port you are using.  Because all Emacs does when you set
ispell-personal-directory is to invoke Hunspell with the "-p PDICT"
command-line argument.  If you have Process Explorer installed, you
should be able to verify that Hunspell is indeed invoked with the -p
option as above, and if that is so, then the part of Emacs and
ispell.el works correctly, and the problem is in Hunspell itself.

I looked into the Hunspell's sources, and I think I know why this
happens.  Hunspell has a peculiar logic when looking for the personal
dictionary.  The outcome of that peculiar logic is that if Hunspell is
invoked with "-p PDICT" command-line argument, and PDICT is an
absolute file name, that file must already exist, or else Hunspell
will decide it cannot use it.  And Emacs always invokes Hunspell with
an absolute file name of the personal dictionary.

This is arguably a bug in Hunspell, but a workaround is to create an
empty file at the location where you want the personal dictionary to
be, and then restart the speller.

   ^^^^^^^^^^^^^^^^^^^^^^^
If the above is the literal value you tried, it is again incorrect:
each backslash should be doubled.  If you did double them all, or used
forward slashes, then there's a different bug in your version of
Hunspell; it worked for me once I understood the problem.

Did you veryfy that Hunspell is invoked by Emacs with the correct -p
switch?

Indeed I had doubled them in my emacs init file and used backslashes ...
that was a typo above.

I just checked process explorer and obtained the following command line
args:

c:\msys64\mingw64\bin\hunspell.exe -a "" -d en_US -i UTF-8

This did not change regardless of what string I used for ispell-cmd-args in
my emacs init file.  I tried first "-p C:\\Users\\xxxx\\.hunspell_en_US,"
under the assumption that ispell would append this to the existing default
set of cmd args, after creating an empty .hunspell_en_US file in my home
directory, and then tried setting it to

"-d en_US -i UTF-8 -p C:\\Users\\xxxx\\.hunspell_en_US"

again to no avail.

Please be sure you are testing this correctly.  Here's a step by step
procedure starting from "emacs -Q":

  emacs -Q
  M-: (setq ispell-program-name "hunspell") RET
  M-: (setq ispell-personal-dictionary "C:/Users/xxxx/.hunspell_en_US") RET

Now go to some word in *scratch* and type M-$.

Then look with Process Explorer how Emacs invoked Hunspell.

When I do the above, I clearly see the "-p PDICT" command-line
arguments with which Emacs invokes Hunspell.  I made a point of
testing this on Windows with Emacs 28.2, which is what you have, and
it worked for me.

If the above procedure works for you, please see what you are doing
differently in your "normal" Emacs sessions.  In any case, using
ispell-cmd-args is not the recommended method; you should instead
customize the variable ispell-personal-dictionary, which is provided
for this purpose, and customize it before starting the spell-checker,
or restart the spell-checker with "M-x ispell-change-dictionary" after
customizing.

This bug exists even on GNU/Linux, so requires such customization:

  (unless (file-exists-p "~/.hunspell")
    (shell-command "touch ~/.hunspell"))
  (setq ispell-personal-dictionary "~/.hunspell")

Yes, the code which does that in Hunspell is not Windows-specific.

Thanks for the detailed suggestions -- it now works.

From what I can tell, the issue was the double backslashes not being
accepted
in the file path for the hunspell personal dictionary.

So I guess we can close this bug now?

It should works either way.  Maybe you didn't double every backslash?

Yes, with the caveat that it would be nice to document this somewhere.  I
opened
up a bug report on the hunspell github repository about this issue and did
not
receive a response, so I'll respond to my own issue with this latest
information.

Just double-checked my setup and indeed the problem reappears when I
substitute
double backslashes for all of the forward slashes.  Also tried using the
cygwin-style "/c/..."
convention since everything is running (emacs + hunspell) inside an
uptodate installation
of msys2 using the mingw64 repository, and that does not work either.  Only
the
"C:/Users/..." path is accepted apparently.

Elsewhere within my init.el file the double backslash inside elisp strings
works just
fine for Windows file paths.

I'll try to find a place to mention this.

Doesn't happen here.  Please show the exact settings you used.  Was
that in "emacs -Q" or with your customizations?  If the latter,
perhaps some of your customizations get in the way.

Okay, the double backslash works with emacs -Q on my system as well.

Back in my customizations, it looks like I had not rechecked by setting the
ispell-personal-dictionary variable ... was still using the ispell-cmd-args
approach unfortunately.  So it looks like the latter is the issue, because
everything works now per your suggested settings.

I had originally tried using ispell-personal-dictionary before turning to
ispell-cmd-args and now believe that I may have failed to touch the
.hunspell_en_US file first (a known quirk) while I was testing the double
backslashes among other ways of specifying the file path.

So it's safe to close the bug now.

I have more information now regarding this issue, which as it turns out was
not related to my testing the ispell-cmd-args approach or because
I had failed to touch the .hunspell_en_US file per the known quirk on
windows.

In my init.el file, after the lines:

(setq ispell-local-dictionary "en_US")
(setq ispell-personal-dictionary "C:\\Users\\...\\test-personal-dictionary")
; the personal dictionary file has to exist, otherwise hunspell will
; silently fail to use it
(unless (file-exists-p ispell-personal-dictionary)
  (write-region "" nil ispell-personal-dictionary nil 0))

I had the following line:

(use-package flyspell
  :ensure t)

When I removed this line, flyspell started to recognize the
custom ispell-personal-dictionary that I had specified.

Since flyspell is now built into emacs, I'm a little unclear on
why reloading the package without changing any other options
would block an underlying ispell setting.

This also explains why everything worked just fine when I tested
setting a custom location for the personal dictionary using emacs -Q.
