Parent article: Toward a "modern" Emacs

After reading the comments here it looks like most of the people have never used Emacs or tried it once 30 years ago (no Unicode support? https://lwn.net/Articles/832663), cannot use mailing lists what indicates that they don't have too much experience with open source in general, and that they feel modern because they are so modern and cool because they use C-c and C-v to copy and paste text what actually means that they are inflexible and unwilling to learn new ways of doing things and may not even know what C-c does in the command line.

I have been using Emacs for 10 years and it works well for me - I use Elpy for Python, go-mode for Go, cc-mode with company-mode and smart-compile for C, Magit for Git integration, yasnippets. All of the features you'd expect from contemporary IDEs are here - auto complete, on the fly syntax checking, integrated debugger, refactoring capabilities, showing documentation for symbol at point, narrowing, jumping to definition. It's hard to come across file written in a programming language for which Emacs wouldn't at least provide syntax coloring out of the box - I've just tried .java, .kt, various assembly types.

I've also used Jira mode that allowed me to list all tasks assigned to me, comment on them and create new tasks without leaving Emacs. Additionally, I can use Emacs without touching a mouse and in server-client mode so I have access to all existing buffers when writing an e-mail in Mutt or when using sudoedit. I use zenburn theme because I prefer darker colors.

A couple of things I looked into recently: JSON mode - it's here https://github.com/joshwnj/json-mode, Rust mode - it's here https://github.com/rust-lang/rust-mode.

If you cannot figure out how to use a mailing list feel free to ask questions on Emacs SE: https://emacs.stackexchange.com.

Nothing is perfect though - one of the things I don't like about Emacs is that it cannot be run under Wayland without using XWayland because 'it is not a proper gtk application' or whatever https://emacshorrors.com/posts/psa-emacs-is-not-a-proper-....

Been living under a rock?

I try to avoid the word "modern" when possible but it's getting difficult when the developers relying on email the most use the words "stone tablets".

Are you trying to say that mailing lists are not used any more? What are Mailing List Archive https://marc.info, https://gmane.io or lore.kernel.org for? Yes, there are many projects on Github, Gitlab etc. but there are also some projects that only have mailing lists. This is also why there are `git send-email` and `git am` in Git. I hope Git it's modern enough?

There is a whole generation of developers that only use web interfaces (principally GitHub), those interfaces are getting to the point where they also replace local editors like emacs or VSCode and compilers and so on.

Not using mailing lists does not imply coding in a web interface but yes, that's a good (counter) example.

And? There is also a whole generation of developers who have never used C or command line but you cannot say that these things are not used any more. Everyone uses e-mail though, using mailing list is easy especially if you do not need to subscribe. If you don't know how to use a mailing list you will never contribute to Linux or Freebsd kernels or projects such as busybox, U-boot and others. Newer projects such as https://core.dpdk.org/contribute (started in 2012) that I got interested in lately also use mailing lists. So it's not about whether someone has used it or not - they can always give it a try, someday they might have to if they'll want to contribute and there's nothing wrong with that - this is called learning.

Good thing no one said that then but please keep arguing with yourself again.

I've already used mailing-lists and I'm still using some sometimes. That's why I try to avoid them.

> Everyone uses e-mail though, using mailing list is easy especially if you do not need to subscribe

If you're interested in learning this assumption has already been questioned and discussed a million times on this site - and others.

Random example: https://lwn.net/Articles/817668/

By the way it's not mailing-lists that seem to be losing steam; email as a whole too. "Blame" Facebook, Whatsapp and what not.

Exactly one of the top issues that has already been discussed a million times, welcome to the party. Better late than never.

You see, and I *prefer* using mailing lists over Web-based forums.

Wow, if you didn't tell me that I wouldn't even know that
https://discourse.debian.net exists. I have never used Discourse but
I'd gladly start if there was a need but e-mail would still be
better. I can use both - no problem for me but I see that some
self-called "modern" people (not you) are rather close-minded and
inflexible.

I don't use e-mail on my phone when I want to ask someone if we hang
out this evening, I use Signal. But e-mail loosing steam? Maybe but
I'm not sure it will stop being relevant until the end of my "career"
but I wouldn't be so sure about Facebooks, Whatsapps and other today's
rockstars. At least, e-mail serves as a login/registration mechanism
and notification system in many places. It's still widely used in
business because it's versatile, unified, independent and secure (but
only if set up correctly).

Well, if someone cannot figure out how to use e-mail they'd better not
contribute.

I clarified "this is not what I said". pabs gave a good example that I endorsed. Yet you kept at it. If you're not sure what I meant don't keep making me say what you fancy answering instead. This site is one of the few left where people try to understand each other in the comments section.

I agree with most of your technical description of email here but it doesn't automatically follow that email should be used for everything including code reviews and project collaboration, no more than it implies email is good substitute for databases (which most "modern" tools rely on = not so random example).

> > This assumption has already been questioned and discussed a million times on this site - and others.

Yet I can't resist addressing this particular, knee-jerk justification:

> Well, if someone cannot figure out how to use e-mail they'd better not contribute.

s/figure out/like/

I know how to use email; I even knew how to send a message with telnet 25 and retrieve them on port 110 (before everything became encrypted). I just _prefer_ to avoid email when I can because I find it messy, disorganized and not productive.

I perform a number of code reviews daily and I can understand the temptation not to make too easy to contribute but seriously: use email because you think it's the best way for the project to communicate, not because there are technically easier ways to communicate!? That's the worst reason ever and possibly turning off people who like email but not this kind of attitude and to be honest it lowers the credit of other, much better points you made. Don't mix up two totally different problems.

For instance a much better way to filter contributors and save maintainer time is not to start reviewing anything until all tests and checks pass in CI (or have a very good, written justification why they don't). Now you know the wannabee contributor had the technical skills to perform something actually useful and relevant: reproduce and troubleshoot failures and fix them. If no CI failure (for instance because of lack of test coverage), asking for new tests is another much better litmus test.

This is just an example I bet you can find others. BTW any _single_ litmus test carries a "monoculture" risk.

In general creating an artificial shortage of contributors because there is a shortage of maintainers is playing with fire from a long term, natural selection perspective, so proceed very carefully. Even betting you'll be the next "COBOL generation" pulled out of retirement at great expense would be risky ;-) There are many open-source projects to contribute to, many more than ever before and there is a shortage of smart contributors too. So good luck finding your next generation maintainers if you purposely rely on a litmus test as bad as "Do you like email?"

Everybody does. And I didn't mean that YOU don't know how to use
e-mail - I meant that if someone wants to contribute to a project that
uses e-mail they should be intellectually able to figure out how to
use their e-mail client, git-send-mail and git-am. Well, I did and I'm
not the smartest person in the world, I'm actually quite dumb.

Cool, I use telnet only for tests. I use Mutt + msmtp + offlineimap +
K-9 Mail on the daily basis.

> I just _prefer_ to avoid email when I can because I find it messy,

And I find e-mail something completely opposite - organized (mutt has
good searching capabilities: I can filter e-mails by From: or To:
headers, by subject, by e-mail body; I can move e-mails to other
mailboxes; can easily backup my ~/.muttmail even though all messages
are also kept on the server; I'm notified about new e-mails on my
phone; I can read and reply to e-mails on my phone and thanks to IMAP
they are synchronized with mutt) and productive - I don't have to
leave command line and since I use Emacs to write the body I have
access to all existing buffers as I explained above.

As I explained, I find e-mail technically easy to use. I also find web
forms technically use to use though slightly less convenient because I
hate using mouse (I'm using tridactyl in Firefox to overcome this
problem) and because web based forums are not so flexible, cannot be
backed up locally and do not provide as good searching capabilities as
mutt does. So yes, I find e-mail the best way for the project to
communicate.

I don't get it.

Yes, this is good.

ok but what's your point here? Are you saying there is no CI on
mailing lists? There might be - there is one on LKML for example, and
they also have a web based interface that shows all patches sent,
their state and shows the discussion
https://lore.kernel.org/patchwork/project/lkml/list (I heard managers
like it this way).

But this is not 'artificial shortage of contributors', I don't know
how did you come to this conclusion. What if project A uses Github but
someone who wants to contribute used to work for years in project B
that uses Gerrit and doesn't know how Github works (and these 2 tools
are really different technically) - is project A intentionally
creating shortage of contributors this way?

> Even betting you'll be the next "COBOL generation" pulled out of

Don't worry about me, I have to work for another 35 years to achieve
retirement age. I expect to see a lot of breakthrough changes, new
ways of doing things, new ideas and adapt to all of them. Just a few
months ago I switched to i3 to be ready to switch to Sway on Wayland
and a few days ago I got a new M.2 SSD disk, much faster than the ones
I have used so far. I'm not and am not planning on being stuck in the
past.

> There are many open-source projects to contribute to

I know, I contributed to many.

There are many although their quality and usefulness vary.

Smart contributors - yes, smart.

I don't do that.

This is not really about configuring an email client or using git. It's about organizing the information overload you're describing:

> And I find e-mail something completely opposite - organized (mutt has good searching capabilities: I can filter e-mails by From: or To: headers, by subject, by e-mail body; I can move e-mails to other mailboxes; can easily backup my ~/.muttmail even though all messages are also kept on the server;

I prefer not having to do most of these _at all_.

BTW referring to mutt in a discussion about ease of use is... interesting?

> As I explained, I find e-mail technically easy to use.

Great but this discussion isn't about you cause you already prefer email.

> I also find web forms technically use to use though slightly less convenient because I hate using mouse

You just hit the second most common misconception in this discussion. While the web is clearly the preferred database interface these days, there's no fundamental requirement for it to be. If some people manage to get something out of github from Emacs (github = the closed source poster child of open source), surely it's possible to do even better with alternatives to github.

> ok but what's your point here? Are you saying there is no CI on mailing lists?

Again, no idea how you got that. Information overload?

> they also have an interface that shows all patches sent, their state and shows the discussion https://lore.kernel.org/patchwork/project/lkml/list (I heard managers like it this way).

Exactly: this as close to "modern" as kernel development gets. Re-constructing a missing code review database from loose emails as opposed to having some sort of email (and other) interfaces from a code review database like everyone else does. A code review database means someone joining the project 2 years later and debugging a long standing issue can find all the relevant information and barely any irrelevant information in a jiffy. No email organization needed. Meanwhile: https://lwn.net/Articles/797613/

> is github project A intentionally creating shortage of contributors this way?

Yes but not intentionally and (IMHO) not as much as with email. I mean I've never read this: "Well, if someone cannot figure out how to use github they'd better not contribute." In fact github's constant efforts are the exact opposite of that.

> > There are many open-source projects to contribute to

Just to be clear: I meant including many that do not require email.

I'm pretty sure you just did.

Also sure you still have a lot of past discussions to catch up with. Write less and read more (and more slowly).

Information overload? E-mail contains From:, To:, Subject: and
body. How is this different from anything else?

You don't have to do that, you can. And what exactly would you prefer
not having to do? You prefer not doing backup ("there are two kinds of
people...")? You prefer not having easy searching by author or
subject? You prefer not using your smartphone? You prefer not using
the command line? You hate synchronization and notifications?

> BTW referring to mutt in a discussion about ease of use is... interesting?

Sorry, "easy to use" might mean something completely different to
different people, don't you think? For instance, I find Gmail flashy
clicky web interface absolutely disgusting and unusable.

Surely it's also possible with e-mail. BTW, I have never wished to use
Github from Emacs. You can use Github like a regular repository and
you can use hub command line tool to fork and push pull requests
etc. and you can read and reply to all tickets by e-mail.

There are no projects that do not require e-mail because you have to
use e-mail to register. Yes, I've used Gerrit, Gitlab, Github and
Bitbucket. I also use StackExchange a lot (Emacs has a very nice
Markdown mode) - it's heavily web based. But what's the point? I have
used many different things, have self-called "modern" developers too?

No. Use the right tool for the job. If you want to contribute, follow
the rules. You don't have to like them, it's not your project.

Honestly, I have a very hard time trying to understand your

I shared a number of references but it doesn't seem you tried to read any other post. You're only interested in explaining how perfect email is (for you).

I should point out here that his comfort with email is fine, just as the email-centric development model of emacs (or whatever) is also fine -- it serves those doing the work quite well. Indeed, hyper-customizable tooling is the entire raison d'etre of emacs, and non-email server-based workflows invariably require using someone else's tooling.

If someone wishes those folks to change a development model/methodology they personally find very productive (and aligns with their overall principles) for something significantly different, that someone will have to show how those changes will be an overall improvement _for the existing team_ -- they are, after all, the ones who are doing the work, and are all volunteers.

Anyway.

Totally agreed - as long the existing team doesn't "live under a rock", doesn't place non-technical objectives too far above technical ones and can generally listen to unusual perspectives. Otherwise it would just be a lost cause it would be better to either fork or look for alternatives and not just for tooling reasons.

Another option when you can afford it and when the size of the project justifies it is to "fragment and bridge" the tooling, this is what happens for the kernel for instance.

Depends on the project.

But who does that? I'm not a member of Emacs core team and never sent
any patches but I'm glad they think about the future, I'd like to see
how Emacs evolves in the next decades. I also described how Emacs
fills all of my needs as a programmer in year 2020, mentioned Emacs SE
(I forgot r/emacs) and stated that there are many other projects that
use e-email and that you should know how to use it. You somehow
focused on that e-mail thing and started convincing me that it's very
very bad and should not be used. Nobody "lives under the rock" here.

Emacs has been forked multiple times, and it will be forked multiple
other times if there is a need. For me, making it work on Wayland
without using XWayland is now one of the most important things to
do. I'd gladly start using Wayland on the daily basis without any
leftovers from X.

Emacs is, however, a much smaller project compared to kernel
(actually, most OS projects are smaller than kernel). It's also not as
critical and there are not so many eyeballs looking at it.

Well, yes -- the developers doing the actual work are the ones who ultimately decide what direction a project takes, up to and including forking it if the nominal "owners" are intransigent.

If RMS is truly the only impediment to "progress" in emacs, then its most productive developers will revolt and fork it. It won't even be the first time this has happened to a core GNU package.
