Well, that risk paid off because by all accounts it seems that noone
suffered (and some people benefited), so that argues in favor of taking
that risk again.

If you are right, we will be able to make this on by default in Emacs 31 (assuming we introduce the opt-in feature in Emacs 30, that is: no one has yet shown the code, so we are discussing a highly theoretical feature).

This is not so much about buggy .dir-locals.el, this is about non-buggy .dir-locals.el that have customizations for nil mode -- those customizations might not expect non-file modes to be affected.

The difference is that if we say this should be in .dir-locals.el, we place the burden on the users, whereas if we do what Juri suggested, we solve this ourselves at least for modes that come with Emacs.

That commit I referred to had AFAICT the same effect as the one
discussed here: it made some modes (diff-mode, log-edit-mode, and a few
more) obey dir-locals whereas they didn't before.
And dir-locals existed since several years before that.
Why would it be more likely for them to have .dir-locals which
accidentally affect grep-mode than diff-mode/log-edit-mode/...?
AFAICT it risked the exact same backward compatibility problems.

I'm quite serious. From where I stand, I think most users would
want to enable this feature in they have a situation where it affects
the behavior of Emacs.

I definitely agree with this. Eli's worry is about retaining compatibility with buggy code (in this case, a hypothetical .dir-locals.el that doesn't properly map variables to the desired modes), so the compatibility workarounds, if any at all, should be transitional.

And then there's also the case of buffers that don't really "belong" to a directory, such as *Help*. Do you think there's a reliable way to distinguish those from the rest? (By the way, *Help* and friends get stuck forever in whatever default-directory they were first created; so for instance if you do C-x C-f in a *Help* buffer, you will see a random directory as starting point...) > Or such a new option could be a list of non-file modes that should > support dir-local variables. I'm not a big fan of this idea. The .dir-locals.el file is already a list of modes, you can decide there which modes you want to be affected.

I can relate to that, but I can't remember bug reports (nor questions
from confused users in other channels) when we made that change, so
I don't see why we should consider that specific past choice to be
a "past mistake".
Also, I'm not seeing why "That's not the same".
> Like I said: I'm okay with this change provided that it is opt-in.
The problem with that is discovery. Should we add a message like
"ignoring dir-locals. See obey-dir-local-variables-in-all-non-file-buffers"?
And of course a related question is what kind of granularity to use for
the "opt-in"? Will we add a new var every time we notice another (set
of) buffers for which we should apply dir-local vars, or would it be OK
to have a single variable?
If it's OK to have a single var: why should this var not
apply to diff-mode, log-edit-mode, ...?
Or should this var contain a list of modes which allow it, so we can
make it default to (diff-mode log-edit-mode ...)? And maybe also allow
a t value?
And since this var is needed only to avoid breaking backward
compatibility, it would be desirable to have a plan to get rid of it in
the longer term.

FWIW, back in 2010 (commit 8117868f0ce6) when we added support for
dir-locals to non-file buffers, we did it without even a config var to
turn it off.
AFAICT the `dir-locals.el` format should already be sufficiently
flexible to make it easy for users annoyed by the new behavior to
recover the old behavior (without affecting older Emacsen).
I think we should make an effort to enable dir-locals in as many buffers
as makes sense (but that can't be all buffers, because many buffers
aren't really related to any particular place in the file system, in
which case using the dir-locals setting of the directory that happens to
be current when the buffer was created is too arbitrary).

We can later make it the default if enough people like it and not many complain about it. Thanks.

Do you have a concrete example? You are entitled to your opinions, but this is clearly a change in behavior that will affect a lot of users (since compilation-mode and its descendants are very popular and widely used). Therefore, I don't understand why you need concrete examples: the issue is crystal clear just by thinking about it. > The dir locals mechanism is very precise and easy to use.

This seems rather hypothetical to me. Do you have a concrete example? The dir locals mechanism is very precise and easy to use. Anything not intended to affect compilation buffers should be put under prog-mode (or a descendant), text-mode, or whatever else it's actually intended for. On the other hand, imagine this situation: you're working on a project with very long lines in some files, so you want your grep buffers to look more compact. Then you type M-x add-dir-local-variable RET grep-mode RET truncate-lines RET t RET Wouldn't you be very confused that this doesn't work? > Also, this needs a NEWS entry, I think. > >> + (unless (buffer-file-name) >> + (let ((sym (make-symbol "hack-dir-local-variables-non-file-buffer"))) >> + (set sym #'hack-dir-local-variables-non-file-buffer) >> + ;; Ensure hack-dir-locals is called only after a derived mode is set. >> + (push sym delayed-mode-hooks))) > > Why such a complicated way of using the symbol of a function that's > defined in a preloaded Lisp file? Am I missing some subtlety here? This is because delayed-mode-hooks is a _list of hooks_, not a hook. Adding (the name of) a function to it doesn't work.

I must say this is not very convincing. What bothers me is that .dir-locals.el in a directory is not meant for compilation-mode and similar modes, so settings there that are not specific to modes could get in the way in *compilation* and "grep* buffers. But if this is optional behavior, by default off, I don't think I'd mind.

Since compilation buffers go as far as to print the directory they're
running on at the top of the buffer, I think it's pretty clear they
should receive dir-local variables.
So I'd suggest the attached patch, which does that and also removes a
more limited mechanism I added some time ago to allow compilation with
project-specific settings. I've CC'ed Stefan since at the time he kind
of supported the changes I'm now suggesting to remove.

Subject: [PATCH] Add dir-local variables to compilation buffers
* lisp/progmodes/compile.el (compilation-mode): Arrange for dir-local
variables to be hacked into to non-file compilation buffers.
(compilation-start): Remove a less flexible solution to set up the
compilation environment (cf. discussion in bug#50607).

This observation makes sense, but it mostly applies to the good old 'M-x shell', not to 'M-x project-shell', other language interpreters, or to compilation buffers. By the way, I now realize that 'M-x compile' doesn't use comint-mode by default. Which raises the same question: should compilation-mode call hack-dir-local-variables-non-file-buffer? > If you need that for some particular use case, can't you call it from > comint-mode-hook or something? Sure, it's an easy customization, but the question is whether it's the expected default behavior. :-)

Is there any reason to not do it? It doesn't sound right to me to do that by default, since comint is used for shell-like interpreters, and those tend to change directories at will. Which means that dir-locals for some random directory doesn't necessarily take such modes into consideration. If you need that for some particular use case, can't you call it from comint-mode-hook or something?
