bug#10754: define-minor-mode and doc of derived mode

[Glenn Morris]

Package: emacs
Version: 24.0.93
Severity: wishlist

If you use a nil DOC argument with define-minor-mode, it constructs a
doc string for you. The information in this doc string is almost always
applicable to the derived mode (it explains how the mode's ARG works).
Often you will basically want to duplicate this info in the mode's doc,
and add a little bit more. So it would be nice if there was some token
you could write in the DOC arg that gets replaced with the default
doc-string.

Eg:

(define-minor-mode foo-mode "%default-doc.

Foo mode is fantastic because of these reasons... " ...)


This would also save you having to change the doc of foo-mode if the way
define-minor-mode treats ARG changes again.

I don't know whether %default-doc (or whatever) should include the first
line "Toggle ... on or off.", in which case it would be restricted to be
at the start of DOC, or just the part about ARG, in which case it could
come anywhere in DOC.

On reflection, I think it's just the bit about ARG that would be useful.
So maybe a %{arg} construct anywhere in DOC.

Reposting to the thread instead of sending this just to Glenn.

There are over 200 modes that use define-minor-mode. I'm not sure how
many of those docstring have argument documentation. For some of those
modes documenting arg doesn't make much sense.

For those who have an arg document, does it make sense to do them all in
a single patch ? Also, is there any consensus on using %{arg} ? I have a
local patch with linum-mode changed, which I can send for review.

Is this related to bug #29497?

I wasn't aware of that bug. Yes it is trying to address the concern in
bug #29497
as well as #30610

Fine by me (tho I'd replace "will be replaced by a docstring explaining"
with "will be replaced by a paragraph explaining").

Sounds good. I can make this minor edit and audit the rest of the minor
modes.

I just thought of an alternative approach. Instead of interpolating the
docstring we could append the extra argument description to the
docstring ? We can add an optional arg to `define-minor-mode'.

FWIW, it's the approach I would have taken.

I'd rather avoid it if I can.

Great. I changed the patch to append to the docstring instead of
interpolate it. I like this approach better, it is cleaner imho.

I meant a keyword argument when I was saying optional. I forgot that
`define-minor-mode' takes actual optional arguments.


I attached the new patch, below. If this looks good, I will amend the
patch to include other minor modes.

That's what I understood, and I'd still rather avoid that.

I think we can avoid it by looking for the presence of ARG in
the docstring (or by simply always adding it, and then going through
the various minor modes and remove the corresponding text from their
docstrings).

I think this can work, but it doesn't feel very elegant or obvious from
the pov of the caller of `define-minor-mode'. What's wrong with adding
an extra keyword arg ?

I think this change needs to be backward compatible. There could be
other callers that aren't packaged with Emacs.

I think in the long term (asymptotically), the arg is unneeded.
But if we add the arg, the long term will be that *all* calls will use
the arg, so we'll never be able to get rid of it.

I'd be OK with an arg of the form :dont-add-arg-paragraph (for those
hypothetical cases where the paragraph is undesirable) but not
:add-arg-paragraph.

Having the same text twice in the output of `C-h f` is fairly harmless
in my opinion.  We've had similar situations where `C-h v` automatically
adds text like "this is only for interactive use" even tho the docstring
may already say it.

I'm worried about minor modes that don't even mention the argument. Not
sure if that should be a concern since they should be documenting the
ARG in the first place. I can provide examples, but the Emacs codebase
has a few of those.

Sounds good. I will make this change and reply with a patch.

I suspect that it's a misfeature which would be fixed by always adding
that paragraph.

Exactly.

The only problematic case would be if adding this paragraph would be harmful.

I went through all minor modes and removed any documentation related to
ARG from the docstring that is supplied to `define-minor-mode'. IMHO, I
like the change a lot. It removes 500-ish lines of documentation and
fixes a lot of docstring that were incorrect.

The only problematic modes are those with a large keymaps in the
docstring. The argument doc paragraph ends up being outside the visible
area on the screen which feels awkward. That said, I'm feel the benefit
outweigh this awkwardness.

Finally, I touched around 130 .el files. I wasn't sure if the commit
message should reflect all those changes, given the change is somewhat
systematic.

Maybe we could add the paragraph at the first empty line (if there's
one), instead of always at the end?

But overall, LGTM,

Sounds reasonable, I was hesitant to make the implementation more

Thanks for taking a look. fyi, the current implementation replace the
last "\n\n" instead of the first "\n\n". This is either a regression or
a bug in the documentation of `replace-regexp-in-string'. The patch is
doing the following expecting "doc" to appear between "foo" and "bar",
but instead it is inserted between "bar" and "baz"

    (replace-regexp-in-string "\\(\n\n\\).*\\'"
                              "\n\ndoc\\1"
                              "foo\n\nbar\n\nbaz"
                              nil
                              nil
                              1)


According to the doc ti should work:

    To replace only the first match (if any), make REGEXP match up to \'
    and replace a sub-expression, e.g.
      (replace-regexp-in-string "\\(foo\\).*\\'" "bar" " foo foo" nil nil 1)
        => " bar foo"

I'm happy to open a new bug for this, but I don't think it is a blocker
to merging this change.

The trick is that "." matches anything but a newline, using (.\\|\n\\)
instead works as expected:

(replace-regexp-in-string "\\(\n\n\\)\\(?:.\\|\n\\)*\\'"
              "\n\ndoc\\1"
              "foo\n\nbar\n\nbaz"
              nil
              nil
              1)

Thanks that worked. Totally missed that "." doesn't match newlines in
the documentation.

attached a new patch with the fix.

I prefer this text (which also fixes a problem with only one space
between sentences):

  If called interactively, enable %s if ARG is positive, and
  disable it if ARG is zero or negative.  If called from Lisp,
  also enable the mode if ARG is omitted or nil, and toggle it
  if ARG is `toggle'; disable the mode otherwise.

Two spaces between sentences, please.

Thanks.

No objections, but a few minor nits, after which this can go in.  The
master branch, I presume?
