I'm not sure if we're talking about the same thing. Docstring of
`LaTeX-indent-environment-list' says:
,[ C-h v LaTeX-indent-environment-list RET ]
| LaTeX-indent-environment-list is a variable defined in ‘latex.el’.
|
| Alist of environments with special indentation.
| The second element in each entry is the function to calculate the
| indentation level in columns.
|
| Environments present in this list are not filled by filling
| functions, see ‘LaTeX-fill-region-as-paragraph’.
|
| You can customize this variable.
|
| Value:
| (("verbatim" current-indentation)
| ("verbatim*" current-indentation)
| ("filecontents" current-indentation)
| ("filecontents*" current-indentation)
| ("tabular" LaTeX-indent-tabular)
| ("tabular*" LaTeX-indent-tabular)
| ("array" LaTeX-indent-tabular)
| ("eqnarray" LaTeX-indent-tabular)
| ("eqnarray*" LaTeX-indent-tabular)
| ("displaymath")
| ("equation")
| ("picture")
| ("tabbing"))
`
and the one for `LaTeX-fill-region-as-paragraph' says:
,[ C-h f LaTeX-fill-region-as-paragraph RET ]
| LaTeX-fill-region-as-paragraph is an interactive native compiled Lisp
| function in ‘latex.el’.
|
| (LaTeX-fill-region-as-paragraph FROM TO &optional JUSTIFY-FLAG)
|
| Fill region as one paragraph.
| Break lines to fit ‘fill-column’, but leave all lines ending with
| \\ (plus its optional argument) alone. Lines with code
| comments and lines ending with ‘\par’ are included in filling but
| act as boundaries. Prefix arg means justify too. From program,
| pass args FROM, TO and JUSTIFY-FLAG.
|
| You can disable filling inside a specific environment by adding
| it to ‘LaTeX-indent-environment-list’, only indentation is
| performed in that case.
|
`
Now take this small example:
\documentclass[a4paper]{article}
\begin{document}
\begin{equation}
a
a
a
a
\end{equation}
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
Put the point inside the equation environment and hit 'M-q', nothing
happens. When you type in material, there is a line-wrapping at
`fill-column', but that's all.
So basically this is what happens with Keita's patch: line-wrapping will
happen when you enter math, but hitting 'M-q' later is disabled.
Hitting 'TAB' will adjust the indentation of a line, but there is no
filling. And there is a comment in `LaTeX-indent-environment-list':
;; The following should have their own, smart indentation function.
;; Some other day.
("displaymath")
("equation")
("picture")
("tabbing"))

Thanks for raising this inconsistency. My vote is to harmonize this and
add all math environments to `LaTeX-indent-environment-list',
i.e. disabling filling. Then the question is how a user can control the
custom variable when we add entries to it as a style is loaded like in
your patch above? For example, how can I decide here that "multline"
shouldn't be in that variable? Or am I missing something?

Oh now I understand why I was so confused lately.
How can I turn filling on for these environments.
Disabling filling makes my life harder 😕

Yes. More precisely, auto fill still works. However, explicit filling
invoked by M-q, C-c C-q C-e etc. is disabled.
> Hm, I have not tried that out, but my first impression is: I'd

I have the same idea. It's confusing and inconvenient for users like us.
However,
1. bug#28405 shows that there does exist users who don't think so and
prefer filling is disabled inside math environmnets.
2. Filling has already been disabled in "equation", "equation*" and
"displaymath" environments in AUCTeX. In other words, there is
inconsistency between those envs and "gather", "multline" envs.
Hence I think we should discuss what to do with users of various ideas.

Ikumi Keita
