My resignation from Emacs development

My resignation from Emacs development

[Alan Mackenzie]

Hello, Emacs.

I'm resigning my position as Emacs contributor.

The immediate reason is that, as maintainer of CC Mode, CC Mode's
symbols, its names, were taken by Emacs and used for other purposes
without informing me, much less consulting me.  That makes my position as
CC Mode maintainer here untenable.

Eli Zaretskii and I have had extensive discussions, both in public and in
private email, over the last week or so, but we have been unable to reach
any satisfactory compromise solution.

Names are important.  They have power.  To take somebody's/somthing's
name and misuse it is an exercise of aggression.  Try using "Emacs" or
even "free software" to mean something different, and see just how
quickly you would hear back from Richard Stallman.  This misuse of CC
Mode's "trademarks", the symbols `c-mode', `c++-mode', and perhaps
`c-or-c++-mode', is just such an act of aggression.

These symbols have been appropriated by Emacs to mean "the current
preferred mode for C", etc., rather than C Mode, C++ Mode etc.  In
certain circumstances, in particular, in Local Variables: sections and
auto-mode-alist, there is now no longer any way unambiguously to specify
C Mode or C++ Mode.  Up till recently ("\\.myc\\'" . c-mode) in
auto-mode-alist meant C Mode, and would have had the effect of
auto-loading CC Mode, if needed, and running C Mode.

The change took place in the commit for bug#69191 "New var
`major-mode-remap-defaults`, for packages".  It sounds so innocent, but
is an extremely bad solution for whatever problem (unspecified in the
commit message) it was intended to solve.  A major mode using it changes
the interfaces of other libraries in an uncontrolled way.  This is not
good software engineering.

This bug was raised and committed by Stefan Monnier.  Despite the fact
that the bug fix directly impinged upon CC Mode, and there was even a
change to cc-mode.el in the patch, he failed even to inform me.  The only
two modes substantially affected by this change were ruby-mode and CC
Mode, and it is clear that Dmitry Gutov, maintainer of ruby-mode, was
aware of the change.  Had I known of this proposal, I would certainly
have objected to it.  Stefan is intelligent enough to have realised this,
and maybe his avoidance of open discussion was motivated by this.

Bug#69191 was a big change.  In Emacs, we have a convention whereby big
changes are discussed openly on emacs-devel and a consensus reached
before the change is made.  Stefan Monnier has regularly violated this
convention, possibly believing that his ideas for Emacs are so good as to
be beyond question.  Any attempt to question his ideas is likely to be
met by evasive non-answers, if any response at all is forthcoming.  I
could give several paragraphs worth of justification for these
assertions, but I think everybody here knows I am right.

In Emacs there is also a convention of treating eachother with respect on
the mailing lists.  Sadly this convention is superficial, and seems only
to mean things like not using swear words.  The truly contemptuous
communication style, this evasive non-answering, seems to be regarded as
acceptable.  I suggest that this change.

Stefan's habit of making big changes in Emacs without seeking consensus
is at the heart of why I am resigning.  These changes have caused Emacs a
lot of damage over the years and have caused other contributors,
including me, extra work and difficulty.  Stefan is a Jekyll-and-Hyde
character.  On the one hand, he's a very capable hacker, and is always
ready to help others with technical questions.  On the other hand, as
mentioned, he is contemptuous of the Emacs conventions, and unlike
Richard and Eli, does not have the gift of knowing what the Right Thing
is.

I strongly recommend that Stefan somehow be reigned in and required to
observe Emacs's conventions about open discussion and courteous
communication.  As I mentioned, his violations of these are at the core
of why I feel unable to continue contributing to Emacs.

I will shortly be unsubscribing from emacs-devel.  I intend to carry on
maintaining stand alone CC Mode, and I'm prepared to deal with any CC
Mode issues which arise in Emacs.  Please post these to
bug-cc-mode@gnu.org.

It just remains to say that my respect for Eli and the other maintainers
remains undiminished, and that I wish all of them and the Emacs project
all success in the future.

I regret very much this decision of yours, and urge you to reconsider.
Your many-year contributions to Emacs in general and to CC Mode in
particular are greatly appreciated and will be sorely missed if you
decide to go with this decision.

I must say that I disagree with this assessment of what Stefan did in
that case, and don't find anything unbecoming in his behavior, neither
in general nor in that particular case.  Yes, that change should have
been discussed more thoroughly; no, Stefan didn't do anything that
doesn't happen here every other day, and certainly didn't have any
malicious intentions when he installed that change.

And the same to you.  But please do reconsider.

My resignation from Emacs development

[Christopher Dimech]

The claim that using free software or its associated names constitutes
aggression is fundamentally flawed. Aggression involves hostile actions
meant to cause harm, and using names in a way not intended by their
original authors is neither violent nor malicious.

One of the key principles of free software is that software should be
modifiable, and free to use in any context.  Restricting how names are
used run counter to the ethos to empower users and developers, not to
limit or control their language or expressions.

Although the approach should be reconsidered, there should be some
thoughtful conversation among the community.  Avoiding tones of contempt
or disregard for the foundations laid by previous contributors.

For instance, I agree with you that ("\\.myc\\'" . c-mode) in auto-mode-alist
should mean C Mode.  Although C Mode would mean the emacs preferred mode.
Still, your mode name can be changed for those who want to apply an alternative
mode.  Changing the mode should be a straightforward thing.

The whole thing is about freedom, not erecting some new bureaucracy to police 
how people write their projects.

With a bit of work, I think one could make a Monty Python sketch from
that.

"I want to use that function name."
"What?"
"I want to use that function name. I have the right to."
"But it's already used for 20 years. No reasonable man would..."
"Or woman..."
"Where was I?"
"I think you were finished."
"I have the right to use that function name! I'm born free!"
"From now on, I want you all to call me Loretta"

There are forms of aggression which don't use fists or guns.

Fine.  I put it to you that if somebody were to take the name
dimech@gmx.com and prevent it connecting up with your inbox, you would
be somewhat unhappy.

How very considerate and reasonable of you.  The time for "thoughtful
conversation" around the current matter is long past.  You should
perhaps address your comments to those who bypass and evade "thoughtful
conversation" at the appropriate time.

C Mode has been called that for a long time, possibly longer than you
have been called Christopher Dimech.  As far as I'm concerned, it's
going to keep its name.

It is not unusual for people to do so.  Nobody did any harm.  Some
frustration perhaps.

Emacs is not my inbox.  There are many things I need to get accustomed to.
The final decision has always been with the emacs maintainers.  Perhaps
you could become an emacs maintainer than keeping it non-gnu.

Didn't you think something general as C Mode could produce conflicts with
an built-in emacs mode?  It is customary to include a package name with
other code.

   I'm resigning my position as Emacs contributor.

:-( I hope you reconsider, and that Eli, Stefan and the rest of the
Emacs maintainers find a better middle ground -- CC Mode is amazing --
I too think that "c-mode" should mean CC Mode and nothing else.  This
just all smells of the debacle of pcase...

Some _other_ mechanism to pick between CC Mode and c-ts-mode ... or
whatever should exist, while respecting others namespaces.

If one was to introduce a dired-ts .. and M-x dired "magically"
decides between one or the other, people would be just as angry.

To clarify on this: I've been made aware of the change, just like other 
contributors, from reading the bug#69191 submission. And from my POV it 
didn't make things worse, globally - but reshaped existing problems. And 
it did improve some things - like ones that I had myself submitted a 
proposal previously (https://debbugs.gnu.org/68246#283), which was 
collectively rejected.

To be fair, I have less of a reason to take it personally due to less 
focus on particular major mode(s), and less years of tenure as well.

Speaking of other solutions, maybe you'll want to check out the patch in 
the nearby thread: 
https://lists.gnu.org/archive/html/emacs-devel/2024-11/msg00515.html

That scheme could make major-mode-remap-defaults unnecessary for 
c-ts-mode, or in any case remove the need for the corresponding 
overrides in CC Mode. I'm not sure what migration path should be 
selected, though.

Best,
Dmitry

That is highly regrettable.  You are a valued member of our team, and
it's sad to see you go.

From my point of view, we are still in early days when it comes to the
new tree-sitter modes.  For starters, we do not recommend them by
default, and some language modes are also not yet ready for prime-time.
I'm not even sure that a majority of distros ship the feature in a
useful form yet, but I didn't really check.

AFAIU, the purpose of `major-mode-remap-alist` is to provide a mechanism
to respect what users want.  Where there is disagrement, it concerns the
technical details of how to best achieve that, and to which extent we
should set things up automatically based on indicators such as the user
actions "running a mode", "loading a file", or "running a command".

But the feature has teething problems.  My understanding was that we
agreed in Bug#74339 that the situation in Emacs 30 is already better
than in Emacs 29, and that we will continue working on this in Emacs 31.

For example, it has been suggested that we should replace the automatic
setting of `major-mode-remap-defaults` with an entirely new command like
`foo-ts-mode-prefer`, that would be used as the canonical indication
that a user wants to use the tree-sitter mode everywhere.  There surely
exist other options that we could evaluate also.

For this reason, I hope that there is still room to reconsider your
decision to resign.

This is where I have to disagree quite strongly.  I find the charges
directed at Stefan Monnier both unfair and one-sided.  I fail to see
which of his actions or words that could possibly warrant such a
negative interpretation, or that would justify assuming any ill intent.

I have to agree with Eli.  Although it would, in hindsight, certainly
have been better to discuss these particular changes in more detail in
advance, I don't see that he has done anything very unusual or different
from what most other core contributors do on a routine basis.

I also do not appreciate where it veers into ad-hominem, such as talking
about Stefan M's character, etc.  That is strictly off-topic here, as
you well know, and does not reach the usual high level of standard that
one would expect from one of your posts.

Can we please all remember that we share the same goal here; that we all
want to help advance Emacs and free software?

Thanks for continuing to maintain CC-mode, and likewise.

I hope that you will seriously consider the idea to reverse your
decision to quit Emacs development.  It would be much better if we could
find a way where we can all continue working together.  I'd suggest
giving the idea at least a couple of days to fully consider, though I'll
of course respect your decision either way.

Meanwhile, if there is anything I can do to help improve things, please
feel free to reach out.  Thanks again for all your work on Emacs.

It depends on what you mean by useful.  In Fedora, for example, Emacs is built with Tree-sitter, but each user has to (ask Emacs to) download and compile each parser as they go along.

If any Fedora packagers read this and would like to help with packaging the parsers used by Emacs, that would be welcome.  The tracking bug is https://bugzilla.redhat.com/show_bug.cgi?id=2258924

It’s also worth noting that Tree-sitter itself is somewhat immature; the developers say that until it reaches version 1.0, we should be wary of potentially unannounced incompatible changes (although they are trying harder to avoid this, over time).

For starters: The change in the meaning of `c-mode' and `c++-mode' he
introduced in bug#69191, discussed at length in my last post.  Stefan is
not stupid.  He knew full well what he was doing in bypassing open
discussion about major-mode-remap-defaults.

Number 2: In late January 2024, Stefan decided to replace the customary
list form of interpreted functions with opaque atoms, because the list
form "annoyed" him.  In the ensuing discussion, Richard described the
proposal as "perverse", and both Eli and I were asking questions as to
the purpose of the change.  Only evasive non-answers came back.  There
was certainly no consensus around the proposal.  Nevertheless, Stefan
quietly committed his patch on 2024-03-11 in commit
f2bccae22bd47a2e7e0937b78ea06131711b935a.  Emacs is slightly less
powerful as a result, in that macros can no longer operate on the code
of a function in a reasonable fashion.

Number 3: Stefan introduced pcase.el without any open discussion, and
proliferated it rapidly around the Emacs core, leading to confusion
around the use of ` and ,, certainly on my part.  Now it can be argued
that pcase has been a success, but it could have been so much better if
it had been developed cooperatively.  For years there was no adequate
doc string for `pcase', and even now the doc strings for things like
pcase-let* are woefully inadequate.  Stefan is not good at documenting;
nobody can be good at everything.

Number 4: Some years ago, Stefan removed the documentation of defadvice
from the elisp manual without any discussion.  Despite widespread
protest, he refused to put it back again.  Quite coincidentally, he had
just written and pushed nadvice.el.

Number 5: Previously, there had been an embargo on the use of the CL
library, except at compile time.  This kept the size of the Emacs Lisp
language manageable, and the language easy to understand, and made
maintainers' and beginners' lives easier.  At some stage this embargo
was lifted, and the use of CL rapidly proliferated through the Emacs
core.  Now, it could be argued that the facilities and expressiveness of
the CL lib outweigh these disadvantages.  But it was not so argued.  It
just happened.  Maybe somebody else but Stefan made this change, but it
seems unlikely.  Incidentally, the CL library is badly documented; most
of its functions, macros, and variables lack doc strings, and comments
are sparse indeed.  For example, in cl-generic.el, there is no
description of the structures and algorithms used to implement generic
functions.  "Maintainable" isn't an adjective which springs to mind for
this library.

This "be nice to everybody no matter what they do" and "always assume
the best of everybody" creates the perfect atmosphere for a monster to
flourish in.  Stefan is such a monster; not all the time, not even most
of the time, but in doing the things detailed above, and other things, I
don't understand why you are defending him.

I've had continual trouble over the last ~20 years with what Stefan has
done, and how he's done it.  Nobody else even comes close.  As I said,
this is the root cause of why I'm leaving the Emacs team.  Most of the
time, he is extremely helpful and efficient at maintaining, and I'm
grateful for all the help he has given me over the years.  As I said, a
Jekyll-and-Hyde character.

I have not come anywhere near ad hominem.  It is true that many forums
degenerate into slanging matches which repel decent posters.
emacs-devel is the opposite extreme, sort of touchy-feely where nobody's
allowed to offend anybody else at all, no matter what they do, why and
how they do it.  This is just as unhealthy as the the continual abuse
forums; it leads to the build up of repressed resentment.

Sometimes the truth must be told bluntly, and that is what I have tried
to do here.

Thanks!

I can't honestly see myself changing my mind in the space of days.
Maybe in months, or a year or two.  But I would ask you and the other
maintainers to take seriously the criticisms I've made yesterday and
today.

And thanks for the project.  All in all, it's been a great project to
work on.

Thanks Alan, for everything.

Will you make a package out of cc-mode, or should one use the Hg repo?
