Has enriched-mode become enriched?

Has enriched-mode become enriched?

[Colin Baxter]

Hello,

I noticed a couple of changes in enriched-mode exhibited by the latest
emacs, which are not present in emacs-27.2.

1. It used to be the case that I could set a local variable as

#+begin_src elisp
# Local Variables:
# mode: enriched-mode
# End:
#+end_src

Now the addition of mode after the hyphen gives a File local-variables
error: (void-function enriched-mode-mode). I now have to use

#+begin_src elisp
# Local Variables:
# mode: enriched
# End:
#+end_src

2. It seems I now have to set flyspell explicitly, as in

#+begin_src elisp
(add-hook 'enriched-mode-hook 'turn-on-flyspell)
#+end_src

It used to be the case that

#+begin_src elisp
(add-hook 'text-mode-hook
          (lambda ()
            (flyspell-mode)))
#+end_src

was sufficient for enriched-mode too.

I am wondering if these changes are intended.

Best wishes,

Colin Baxter.

I don't think so.

Could the reason be that enriched.el nowadays uses lexical-binding?

The latter has, to my knowledge, always been the correct/supported
syntax.

Perhaps there was once support for people inadvertently including
a -mode suffix in a "mode:" file-local, but if so then that must
have been removed a while ago.  (I don't have an older version than
26.3 installed on this machine, but that certainly doesn't support
"mode: FOO-mode".)

I see that `enriched-mode' is a minor mode rather than a major mode,
though, so I'm guessing you were doing this in a version of Emacs
earlier than 24.1; either or both of these NEWS.24 entries may well
be relevant:

*** Using "mode: MINOR-MODE" to enable a minor mode is deprecated.
Instead, use "eval: (minor-mode 1)".

*** `set-auto-mode' now respects mode: local variables at the end
of files, as well as those in the -*- line.

I just tried it with Debian's 27.1 and it doesn't work either.
AFAIK it's always been the case that the `mode:` thingy needs to have
the major mode spelled without the `-mode` trailer (this is important
for security reasons, since it would otherwise make it possible to call
any function).

That's the normal form.  Not sure how/why the other one worked for you
in the past.

I think this will depend on the file name: enriched mode is a *minor*
mode, so whether it gets put in `text-mode` or some other mode will
depend on the file's name.

I think you need to investigate on your side to make sure where those
changes come from because I don't think they come from Emacs-27 vs
Emacs-28 (or if they do, I don't think they come from changes in
`enriched-mode`).

First, I wish to thank everyone for their help and suggestions.

Local variable should be 'enriched' and not 'enriched-mode' in emacs-27
and also emacs-28. I hadn't noticed the warning in emacs-27 but I did in
emacs-28 because I had set the latter is set to debug on error.

I'm sorry I didn't look properly at the output. However, I have learnt
that its better not to use 'mode: enriched' at all as a local variable
for the following reason.

1. emacs -Q <RET> (works with emacs-28.0.50 and emacs-27.2)
2. C-x C-f test.txt <RET>
3. Enter some text.
4. M-x enriched-mode <RET>
   Mode-line reads 'Text Enriched'
5. Save the file and kill the buffer.
6. C-f test.txt <RET>
   Mode-line reads 'Text Enriched'
7. Enter
   # Local Variables:
   # mode: enriched
   # End:
   and save.
   Mode-line reads 'Text Enriched'
8. Kill the buffer and open test.txt again
   Mode-line now reads 'Fundamental Enriched'
9. Remove the local variables, save and kill buffer.
10. Open file test.txt again
    Mode-line now restored to 'Text Enriched'

Any text-only options such as flyspell will be lost if 'mode: enriched'
is used.

I have removed 'mode: enriched' from all my enriched-mode files,
which are now well-behaved.


Thanks again,

Colin Baxter.

I was about to recommend you don't advertise proprietary products on
gnu.org mailing-lists, but the above message seems eloquent enough to
recommend against the product anyway ;-)

Yeah, but perhaps this eloquence only talks to people who would run
away screaming at the idea of using that app anyway :-/
