I explained this in my last mail on this thread, to make it short using stderr can't work reliably for parallel builds. Maybe we decide that's good enought but has to be considered now as IMO it's a strong limitation. Andrea

Here come the trouble. Ideally would be great to just emit to stderr and integrate with compilation-mode. My understanding is that this would just not work for parallel builds as the output on stderr can be intermixed, so the idea to dump to a special file. I think (may be wrong) that this guided patching (but also the navigation through the hierarchical hints that your static analyzer produces) should be all handled by an ipotethical dedicated gcc-mode that consume these json files. I toyed already with this approach for the static analyzer hints here [1]. You are correct suggesting that the connection from the stderr output in compilation-mode may not be trivial but assuming this is a requirement we have quite some info in the diagnostic message to search for the corresponding diagnostic in the json. "bar.c:350:3: error: invalid conversion to type 'foo_t'" Maybe we could even add a diagnostic ID to make the connection simpler? Or the other option is that we make it working saftely only for non parallel builds just using stderr, but I don't think this is very future proof, especially given you are constantly adding cool new features to GCC we could make use of :) Andrea [1] <https://gitlab.com/koral/gcc-analyzer-mode/-/blob/master/gcc-analyzer-mode.el>

I'm increasingly warming to the idea of having it be enabled by an environment variable, rather than a command-line option. My thinking is that it's a pain to have to set up the build system to inject a particular command-line option that's intended purely for consumption by an IDE. As an environment variable, the IDE can inject it into the environment, regardless of whatever build system is in use, and then consume the extra output. (For reference GCC's existing environment variables are listed here: https://gcc.gnu.org/onlinedocs/gcc/Environment-Variables.html ) Something like GCC_EXTRA_DIAGNOSTIC_SOMETHING=foo, for some SOMETHING and some foo? I thought about maybe emitting JSON, which would be extendable. But it would have to be all on one line, which is less optimal, and would be much more verbose than the existing format. So maybe just use the existing format, but fixing it so that columns are columns, as discussed. So perhaps a fix-it aware Emacs mode could set this when compiling: GCC_EXTRA_DIAGNOSTIC_OUTPUT=fixits-v2 (v2 since v1 is the existing format from the cmdline option) In his email, Andrea suggests outputting to a file. How would that work? It strikes me as making it difficult to associate the output from stderr with that to the file, or would the output to the file need to replace that from stderr (in which case what about lines of output from "make"? or other build system messages, etc). Arguably these various approaches are a poor-man's version of a language server (I tried implementing that for GCC a few years ago, but my proof of concept was not successful: https://gcc.gnu.org/ml/gcc-patches/2017-07/msg01448.html ) > > Does Emacs have an automated test suite that could test this > > feature? > > Yes, see the tests in the test/ subdirectory of the Emacs tree.

With the caveat that I'm a mere user of Emacs, that sounds reasonable. (I mentioned it more as a complication I thought of that whoever implements this on the Emacs side needs to be aware of). Thoughts? Dave

Hi Dave, If we are searching for a way to ask GCC to dump a file instead of logging to sterr I think Emacs could easily set the env variable before invoking the compilation. Which one I think is to be agreed as would be probably used by a flymake back-end or same other special case as the one discussed. >> > Feature freeze for GCC 11 is about a month away; I'd love for Emacs >> > to >> > be able to consume GCC fix-it hints (and have GCC and Emacs fix my >> > typos for me) >>=20 >> Agreed; let's try to make that happen. > > I put together a test file showing various features to try to ensure > that GCC and Emacs interoperate on this.

Yes we have a testsuite, we could have a test that runs only with like GCC versions >=3D 11 or keep in the testsuite some pre cooked GCC output. Some tests should be easy to write. Andrea

The existing "-fdiagnostics-format=json" GCC option replaces the
existing diagnostic output with a big blob of JSON to stderr, all on
one line. Although I implemented it, I now feel it to be rather half-
baked.
I like how -fdiagnostics-parseable-fixits adds extra lines of output,
with a prefix that's ought to be easy to detect.
BTW, does Emacs set anything in the environment that GCC could detect?

I put together a test file showing various features to try to ensure
that GCC and Emacs interoperate on this. I'm attaching it.
This can also be seen on Compiler Explorer at:
https://godbolt.org/z/zazejq
which adds the existing
-fdiagnostics-parseable-fixits -fdiagnostics-generate-patch
options.
Ideas for other test cases are most welcome.
Does Emacs have an automated test suite that could test this feature?
A long-postponed goal for me for GCC's testsuite is to ensure that fix-
it hints apply and actually fix the problem (clang's testsuite has
tests that verify this for clang's fix-it hints).
Another complication to consider: the locations in a fix-it hint refer
to the original source file, before any changes are made. If the user
interface supports the user e.g. clicking on fix-it hints and
selectively apply them one by one, then after each fix-it hint is
applied, all locations after that point potentially need to be "fixed
up" somehow, to reflect the changes to the buffer. GCC's own code
implements this in gcc/edit-context.{c|h}, for implementing -
fdiagnostics-generate-patch, which applies all fix-its "atomically" -
but the use-case I thinking of involves clicking on fix-it hints one-
by-one in the compilation buffer, perhaps replacing the fix-it output
with an "Apply fix" button.
(to cover this case I made sure the demo file contained examples of a
fix-it hint that adds a line, and one that has multiple fix-it hints on
the same line).
Thoughts?

In GCC 11 we've revamped the column number handling in how we emit diagnostics; see: https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555632.html GCC 11 diagnostics now (by default) should use actual column numbers, rather than byte counts. We haven't changed -fdiagnostics-parseable-fixits; it still emits its range information in terms of byte offsets (and e.g. Eclipse already consumes that option); this is bug-for-bug compatible with clang, I believe (which had that option first). Note that characters != columns, or, at least, we have to be careful about what we mean. Consider the case of 🙂 aka SLIGHTLY SMILING FACE (U+1F642) which is a single unicode code point, but occupies two columns, with its UTF-8 encoding requiring four bytes. When I type it into an Emacs buffer, and look at the column number I see that Emacs appears to treat the character as occupying two columns. Is that the kind of column numbering you would want for machine- readable fix-it hints? Similarly, the column numbering emitted by GCC 11 diagnostics is affected by tab characters as tab stops, which seems to reflect Emacs behavior as well. I can add an additional option for fix-it hints that's similar to -fdiagnostics-parseable-fixits, but with a different output format (or to add an argument to that option, perhaps). Before I do that, I wanted to check that it would be consumable by Emacs. What works for you? Would it help to send the proposed GCC patch to this bug address (or to the emacs-devel list?). The existing option is documented here: https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Message-Formatting-Options.html#index-fdiagnostics-parseable-fixits Alternatively, we already have a JSON output option (-fdiagnostics- format=json); perhaps something like that could be used? Feature freeze for GCC 11 is about a month away; I'd love for Emacs to be able to consume GCC fix-it hints (and have GCC and Emacs fix my typos for me) Dave

Emacs can guess the encoding, but that guesswork is bound to fail. So reporting the offsets in characters (a.k.a. columns) is really a necessity. Thanks.

As Tom(?) noted, I made -fdiagnostics-parseable-fixits report in bytes, partly because that's the status quo for all of GCC's "column" reporting, and partly because that's what clang implemented for this. It appears that Emacs can already decode from byte-offsets in a line back to columns, so this seems like a compatibility detail in case we fix everything to use real column numbers. I'm also an Emacs user (though not a Emacs developer, sorry; my Lisp is practically non-existent) - I just wondered what the status of this is. I'm keen to be able to use it (GCC will get better faster!), even if it's just a new command in compilation mode to go ahead and apply a fix-it hint for the current diagnostic, as seen by next-error, if it has one, maybe prettifying the printing of such lines, with the user having to manually supply -fdiagnostics-parseable-fixits somehow. FWIW GCC 8 is gaining lots more fix-it hints (including ones that add newlines, for missing "#include" suggestions); see: https://developers.redhat.com/blog/2018/03/15/gcc-8-usability-improvements/ for a blog post I wrote about it. Thanks; hope this is constructive. Dave

Its purpose is just showing them, and we, ideally, need both. Flymake is moderately large because it includes some checker definitions. We could extract the core to a separate file. Anyway, yes, a minor mode that would act on the fixits inside the Compilation buffer might be helpful. But that's basically ignoring the prior art in IDEs that you asked about, where "quick fixes" go together with in-buffer visualizations.

I think a better first question would be where this feature would fit among the existing Emacs tools. If we look at Eclipse and friends, we can observe that (almost?) every warning or error that the IDE shows to the user comes with a set of actions, suggesting possible fixes, improvements, etc. Thinking along these lines, the closest things we have are Flymake and Flyspell. The third-party Flycheck is even better is several respects (e.g. it can show a listing of all problems in the file buffer), but sadly we won't be able to use it, since the primary author is sternly against copyright assignment. But it'd be good to teach Flymake about fixits, and when we can't use tooltips, use a text-based prompts a la Flyspell. Bonus points for teaching Flymake to use multiple checkers in one file, and making Flyspell one of them. I guess the first difficulty is how to reconcile project-global compilation logs with buffer-local warnings and errors.

I'm not sure we want to tie this feature to compilation-mode. Many modes that derive from it don't support fix-its, e.g. those of them that run the test suites. And even for those that do, Compilation provides a very basic UI. Even to find and apply all fix-its, we'd need to add some new buffer, to show the list. On the other hand, this can be a quick-and-dirty way to try out the feature and how handy it is. Showing the "quick fix" buttons on top of the fix-it text can be it (not sure it that's the UI you had in mind).

Like I wrote: I think GCC should introduce a (differently-named) option which would report positions inside a line in terms of characters, not bytes. Reports in bytes require applications that use these hints to somehow preserve or reconstruct the original encoding of the file as it was presented to the compiler, something that could be a pain. I understand why GCC developers wanted to be bug-compatible with clang, to allow the various front-ends use GCC without any changes, but it sounds wrong for GCC to be forever stuck with this bad design decision made by clang.

So maybe GCC should have a similar option, named differently, which would report in characters. Anyway, "we have the technology" in Emacs to deal with this.

David Malcolm (who wrote the gcc feature) pointed me at the Eclipse bug for this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=497670 It sounds like they're going to integrate it into their "quick fix" feature, which is an Eclipse thing. They also discuss the need to attach the fixit to an earlier error. Tom

@item -fdiagnostics-parseable-fixits
@opindex fdiagnostics-parseable-fixits
Emit fix-it hints in a machine-parseable format, suitable for consumption
by IDEs. For each fix-it, a line will be printed after the relevant
diagnostic, starting with the string ``fix-it:''. For example:
@smallexample
fix-it:"test.c":@{45:3-45:21@}:"gtk_widget_show_all"
@end smallexample
The location is expressed as a half-open range, expressed as a count of
bytes, starting at byte 1 for the initial column. In the above example,
bytes 3 through 20 of line 45 of ``test.c'' are to be replaced with the
given string:
@smallexample
00000000011111111112222222222
12345678901234567890123456789
gtk_widget_showall (dlg);
^^^^^^^^^^^^^^^^^^
gtk_widget_show_all
@end smallexample
The filename and replacement string escape backslash as ``\\", tab as ``\t'=
',
newline as ``\n'', double quotes as ``\"'', non-printable characters as oct=
al
(e.g. vertical tab as ``\013'').
An empty replacement string indicates that the given range is to be removed.
An empty range (e.g. ``45:3-45:3'') indicates that the string is to
be inserted at the given position.

I think Emacs should support this in compilation mode buffers.
A few thoughts on the implementation:
* The filename quoting stuff will require a bit of unquoting
* The offsets are byte offsets, not columns, which is a bit of a pain
(or at least, it is for me since I don't know how to handle that in
elisp)
* One way for this to work would be to display the buffer and=20
show the proposed change as an overlay; and then use y-or-n-p
to ask whether it should be applied. I was thinking something like:
(defun compilation--fixit-make-overlay (start end text)
(let ((overlay (make-overlay start end)))
(overlay-put overlay 'face 'diff-removed)
(overlay-put overlay 'after-string
(propertize text 'face 'diff-added))
overlay))
With this approach perhaps nothing could be done if the fixit was
already visited, or if the buffer text already matches the
replacement.
* However other approaches are possible, like letting the user request
no confirmation, or request "auto-apply all changes" or something.
Maybe a fixit should be associated with the previous error somehow.
* Allowing "fixit" to be handled specially in compile mode might mean
adding a new "type" value, not sure.
