Hi all,

I noticed a weird indentation using fish-mode (from MELPA). I tried to
understand the root cause and found that the problem only appears when
using native-compilation.
So I open a bug here (and not in the fish-mode repository).


Here is the procedure to repoduce :

With the following init.el :
(require 'package)
(setq package-archives '(("melpa" . "https://melpa.org/packages/")))
(package-initialize)
(unless package-archive-contents
  (package-refresh-contents))
(unless (package-installed-p 'fish-mode)
  (package-install 'fish-mode))

Open the "foobar.fish" file with the following content (no indentation
at this step) :
function foobar
if test -n "$argv[1]"
echo foobar
end
end

Indent the whole buffer with :
- M-x mark-whole-buffer
- M-x indent-region


Here is the result I see :

With Emacs 28.0.91 without native-compilation (or with Emacs 27), the
buffer is indented correctly :
function foobar
    if test -n "$argv[1]"
	echo foobar
    end
end

With Emacs 28.0.91 with native-compilation (after ensuring that the
compilation has been done [*]), the indentation is not the same (and
not correct) :
function foobar
    if test -n "$argv[1]"
	echo foobar
end
end

[*] There is 2 warnings about "docstring wider than 80 characters"
during the native compilation of fish-mode


Best regards,
Frédéric Giquel

Hi Frédéric,

the first time fish-mode is used a trace of its native compilation
should appear in the *Async-native-compile-log* buffer.  Could you have
a look and report what is produced there?

PS you can remove the fish-mode .eln already produced somewhere under
~/.emacs.d/eln-cache and restart emacs to re-trigger native compilation
if necessary.

Thanks

  Andrea

The result of native compilation of fish-mode.el is :
Compiling /home/fred/.emacs.d/elpa/fish-mode-20210215.1114/fish-
mode.el...

In fish/count-tokens-on-current-line:
fish-mode.el:393:8: Warning: docstring wider than 80 characters

In fish/auto-indent-post-indent-check:
fish-mode.el:663:8: Warning: docstring wider than 80 characters
Compilation finished.

If I remove the corresponding docstrings in fish-mode.el, the warnings
disappears in *Async-native-compile-log* but the indentation remains
incorrect.

PS: in my first message, I compared 2 versions of Emacs 28.0.91
(compiled with or without native compilation enabled). We can also
hightlight the problem only using Emacs with native compilation enabled
: if we add "(setq load-no-native t)" in init.el, the indentation is
correct.

Best regards,
Frédéric Giquel

Hi Frédéric,

I've isolated `fish-get-end-indent' as the function causing the
different behaviour.  I'll have a look into what is going on and report.

Thanks

  Andrea

Okay, this is an optimizer bug.

The compiler was convinced the following lambda returned 1 :/ and could
optimize accordingly...

(λ (x)
  (if (eq x 0)
      (error "foo")
    (1+ x)))

I've pushed the fix into emacs-28 as 69e82968d7 as I think this is
important to have in the release branch.  The commit include a testcase
as well.

Frédéric if you could compile emacs-28 and verify it works for you would
be nice (I guess you'll have to clean-up at least the miss-compiled
.eln)

Thanks

  Andrea

I confirm that the indentation issue is resolved.

Thanks for the fix and more generally for your great work on native
compilation.

Very nice, thank you very much for testing and the kind words.
