Well, that would make things less backwards/forwards compatible -- people would be getting warnings when flipping between different Emacs versions.

Since we are admitting that this is data (-> .eld), not code is it even
necessary to worry about how difficult it is two write. Couldn't adding
a comment referencing `add-dir-local-variable', or if necessary some
other, new function be enough?

My only objection to "something like" this is that it appears to be Lisp
code, and people could get surprised when they try to add something that
isn't (eg. a regular `add-to-list' call that had a quote -- beginners
often get tripped up on these minor syntactic points).

Ideally there would be a warning or some way you could find out that
variables aren't loaded, e.g. if you have a typo in
`blink-parenthesis-mode' vs. `blink-parentheses-mode'.

Yes, exactly -- people have to resort to using `eval' (which is
something people should use as little as possible) because our syntax
doesn't allow for simple things like adding values to a list.
Post-mode variables and list concatenation are two things we'd like to
have, but I'm sure there's a whole bunch of stuff people will come up
with if the syntax allowed for (safe) extensions.
I don't know what the new syntax would look like -- the current syntax
is, er, very implementation-friendly and user-hostile. I.e., it's easy
for Emacs to parse, and difficult for people to write:
((nil . ((tab-width . 8)
(sentence-end-double-space . t)
(fill-column . 70)
(emacs-lisp-docstring-fill-column . 65)
(vc-git-annotate-switches . "-w")
(bug-reference-url-format . "https://debbugs.gnu.org/%s")
(diff-add-log-use-relative-names . t)))
(c-mode . ((c-file-style . "GNU")
(c-noise-macro-names . ("INLINE" "ATTRIBUTE_NO_SANITIZE_UNDEFINED" "UNINIT" "CALLBACK" "ALIGN_STACK"))
(electric-quote-comment . nil)
(electric-quote-string . nil)
(indent-tabs-mode . t)
(mode . bug-reference-prog))))
Perhaps a more imperative style would be nice. Err... something
like...
(in-mode c-mode
(set c-file-style "GNU")
(set-early treesit-thing t)
(add-to-list odd-list 3)
(minor-mode indent-tabs-mode)
(minor-mode blink-parentheses-mode))
`safep' would have to be a bit adjusted -- a `safep' for `odd-list'
would be (cl-every #'oddp) etc.
And we'd make the parser backwards/forwards compatible -- i.e., elements
that are unknown to the Emacs version running would just be ignored.

I have often seen projects using `eval' just because the options they are setting are not trivial assignments, but conventional modifications like prepending an item to a list or setting a symbol property (check out the .dir-locals.el for Guix if you want to see a massive "Do you want to accept all these variables" prompt). > Robert

FWIW it could be possible to mitigate this situation using Compat from
ELPA. It could make use of the `hack-local-variables-hook' and
"transparently" add support for .dir-locals.eld. Another idea would be
to provide such a feature as a package that could intentionally be
installed from ELPA for older versions.

We could use an almost syntax-less language with lots of structuring
parentheses (LOSP for short). And we=CA=BCd have to call the file
'please-pwn-my-Emacs.el'
Seriously, having files popping up safe-variable warnings is scary
enough already, do we really need to complicate things by adding
yet-another not-quite-lisp syntax? Is the support for `eval' in
.dir-locals.el not enough?

Actually, 2 strings are already consed up, so this brings it up to 4.
How about something like this instead? It brings us down to 0, as long
as users don't mess with the value of `dir-locals-file'. Maybe it's
even worth installing even if we don't add support for *.eld?

Then, in some undefined future version, we can consider creating > ".dir-locals.eld" files by default, instead. It sort of makes sense to me, but if we're doing a name change, I'd rather make it a functional change, too. It's been pointed out many times that the .dir-locals.el file format is bad -- it's not extensible, and many things have been proposed for extra functionality that's impossible to add today. (For instance -- variables set before the major mode happens, and adding to list variables.) So if we introduce .dir-locals.eld, we should take the opportunity to add a brand new, sensible, extensible syntax, too.

This conses 2 strings, which is a pity, because this code is called a
lot. Can this be done without so much consing for such a simple job?

It's nice if we can use the "*.eld" extension for files that are not
supposed to be executed. But it's hard to just change that outright, as
a file ".dir-locals.eld" won't be used on old versions of Emacs.
So how about doing something like the below, as a future compatibility
patch? Then, in some undefined future version, we can consider creating
".dir-locals.eld" files by default, instead.
