I was also a very early user of Neovim.

The way I personally remember it being positioned was “Vim, but with breaking changes.”

tmp_throwaway_q•12m ago
Yeah, this hasn't been a problem since forever (or at least I haven't noticed). They had to break the undo file format a while ago to actually work correctly for byte-level buffer change events (very important for tree sitter and other plugins listening for buffer changes). The undo file format is versioned, too, so it's not just YOLO'd; Neovim has since forever returned an error saying there's a version incompatibility. The outrage here doesn't make a lot of sense to me.

The original author of this post (on Mastodon) appears to have a bone to pick with Neovim since it's "platforming white supremacists"? I couldn't figure out what this meant. Some sort of internet drama I guess.

The “drama” was linked in TFA:

They are open source developers, giving away free software as a gift. There is no duty here.

We can speak, respectfully, of how important backwards compatibility is to us, and ask nicely for them to give more of their time to support it when their free sodftware isn't backwards compatible. Perhaps we can even offer to help implement it.

But they have no duty to do so or to "care" for their users. (They have already demonstrated they care for their users, btw, by giving them free software.)

EDIT: I missed an important part of the story, which is that they mutated existing files in a non-backwards compatible manner. That should have been avoided, I understand where the (secondary) author is coming from now.

TLDR: Neovim did a breaking change to persistent undo
SigmundA•12m ago
I think this might not be clear on the issue, it broke vim's undo file, as in it deleted it and replaced it with Neovims version.

Just by trying Neovim you can lose your vim undo file.

mcphage•7m ago
…and even trying Neovim out on a file permanently deletes your undo history for that file, even if you switch back to vim.
gavinhoward•41m ago
As a Neovim user, this stopped me dead with painful realization: I may have suffered the same thing but didn't realize it. There was a time when I could not undo something, and it was after a Neovim upgrade.

Unlike Dr. Chisnall, I started my editor journey on Neovim, so it wasn't a transition that bit me. However, if the format of the persistent undo file is unstable, and Neovim just deletes it when it doesn't recognize the previous format, then it seems conceivable (to me) that an upgrade after changing the format would delete the file too.

Ouch. This is making me think about getting off of Neovim. Yes, FOSS comes as-is, but if there's an alternative...

oblio•31m ago
Emacs and Vim are basically like that.

They have very vocal and entrenched users that basically no defaults can be changed lest the single Amiga user will start a huge uproar.

And since they don't really have a BDFL or commercial pressure, they can be super detached even from standards or expectations that appeared 40 years ago.

Neovim was basically a reaction to that, for Vim, where they updated defaults to stuff basically every Unix editor since 2005 has.

layer8•22m ago
It’s somewhat important for privacy reasons that the feature is opt-in. I don’t know if that’s the reason historically, but I wouldn’t want a text editor to persistently store a copy of everything I type without my consent. It’s almost like a keylogger.

Making privacy-sensitive features opt-in is a form of duty of care as well, to avert harm from the user.

skybrian•38m ago
Software developers do sometimes make promises to their users, but I think these promises ought to be explicit rather than assumed. You can't simply assume a "duty of care" and expect that other people will understand them the same way you do.

(Or rather, you can, but you will likely be disappointed.)

dlisboa•37m ago
> the attitude that just because something is a persistent file on your filesystem that contains data that you might want is no reason for their program not to delete it meant they had no concept of a duty of care to their users.

That's the wrong way to look at it. NeoVIM has a different concept of care for their users. They're optimizing for another kind of care, more in line with modern expectations, which VIM did not care about (hence the fork).

It's not better or worse, just different.

This same article could've been written about how VIM has no native LSP integration or autocomplete and they don't have duty or care for their users.

pdonis•35m ago
Deleting important data without warning is not the same as not providing a feature users might want.
mindslight•32m ago
Continuing the analogy - rather than a relationship that could possibly include a duty of care, the relationship of the modern surveillance industry (Faceboot, Google, etc) to its "users" is that of arms manufacturers to military targets.
spamizbad•30m ago
"Vibe shift" is all the rage these days but one area where it's most apparent is modern software.

People of Raskin's vintage had a very humanist approach to computing. The mentality was very much an outgrowth of the cultural revolution of the 60s. Computer usage should be joyful rather than toiling. The computer should help you. It should make you feel good about what you create.

That stands in stark contrast today, where things are more hostile. Not just in terms of "Dark patterns", or writing off user needs for the sake of expediency... but even the way we talk about technology today. You need to use X, do Y or you're "not going to make it" / "escape the permanent underclass". It's bleak.

I recently restored a vintage Macintosh SE I picked up at VCF Midwest and despite its limitations that machine was an absolute JOY to use despite its limitations and nearly 40 years of age. This was a machine and software designed by Raskin's contemporaries and it shows.

ryandrake•14m ago
Software’s purpose is clearly shifting from “what’s good for the user” to “what’s good for the developer.” Instead of enabling me, software now seeks to lock me in. Instead of making my life easier, software decisions are made based on what makes developers’ jobs easier. Instead of being careful with my data, software now comes with giant legal terms that allow developers to be utterly careless with it. Software is now designed primarily to funnel money to the developer, not to bring joy to the user.

And look at this article’s HN discussion. Many people indignantly defending it. “It’s open source. If you don’t like it deleting your data, don’t use it!”

Awkwardly speaking, Microsoft Word is a great example of a program that appreciates backward compatibility.
sdcfgy•27m ago
I've used vim since the first time it appeared in Debian repos. I have been told a thousand times that NeoVim is better, more modern and solves many (conveniently never cited) issues. I just ignored it and carried on. Feeling terribly vindicated at this point as it's a feature I use regularly and have no idea that it would be an issue in NeoVim.
WesolyKubeczek•22m ago
I used neovim because it felt way faster by default. I think treesitter runs circles around what classic vim is using to highlight syntax. That said, I never used both beyond basics, thus no horror stories either.
sdcfgy•19m ago
I haven't noticed any performance issues in vim to start with. It was fast on a 75MHz pentium for me. The syntax highlighting, same. No issues. I don't always use that though because I can't be bothered to set up anything much past the basic config.
jurf•26m ago
To be the devil’s advocate here, I think Vim needs less backwards compatibility, not more. In the sanctifying of “muscle memory” it completely stopped innovation, to the point of slowly drifting to obscurity.

Of the over a hundred students I taught when I helped out in uni, basically no one wanted to learn it, despite my enthusiasm.

And I sympathise. As I get older, I slowly grow more and more distaste for software that does not respect my time enough to give me properly-crafted defaults. Vim, in the age of modern editors, cannot compete. Not without 20 plugins with conflicting shortcuts and its self-imposed cliff of a learning curve.

And I’m saying this from a place of love; I’ve been using Vim (at least as a VSCode extension) every day for the last 10 years. But it never really grew up to the promise that the “Vim Creep” essay [1] gave me.

fatbird•22m ago
Unsaid in the blog post is that disabling persistant undo is one of the most common config changes for vim users who bother to set things up the way they like. Persistent undo is what causes your filesystem to be littered with tilde files, which have the same name but prefixed with a tilde. Every file you touch with vim gets a tilde version. Your ls output becomes polluted with noise.

bigstrat2003•27m ago
Yes, everyone is aware of that. The parent poster was bringing up the example of food to demonstrate that our society does not agree that giving something away for free doesn't mean you have no obligation as to potential adverse effects of the thing.
Grombobulous•25m ago
Analogies like this don’t work when comparing against heavily regulated industry.

Neovim being free software is a lot different than United Airlines giving me a free flight or my doctor giving me a free consultation.

It’s very true that you can go to civil court and make a claim that a business or individual harmed you. If you do that with Neovim the judge is going to pretty quickly read bullet point #7 of the Apache 2.0 license, you’re going to struggle to prove any kind of mal-intent, you’re going to tell the judge that you paid $0 for the software, and you’ll be pretty quickly sent along your way with no damages awarded.

TheOtherHobbes•3m ago
Only in the sense there's no explicit legal responsibility.

Do you really believe developers have exactly zero moral responsibility to their users? None at all?

Really?

Would you still believe that if you found the developers of ssh deliberately included a backdoor for hackers, or neovim was uploading everyone's code to the NSA?

ToucanLoucan•35m ago
It's not poison, it's a broken feature. And you have the source code. Fix it if you like.
pdonis•29m ago
Sure, and then have it break again the next time upstream pushes a change. Or have something else break because upstream doesn't care about breaking things that I'm relying on.

The only way to "fix" this from a source code perspective would be to fork Neovim.

> giving away free software as a gift

Even a gift comes with an implicit promise that it will do no harm. Deleting important data of yours without warning is harm.

timschmidt•28m ago
This gift comes with the following clauses listed plainly in the license file:

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
jstanley•25m ago
I don't think anyone is looking for legal remedies, this is not the right layer.
timschmidt•17m ago
Is some part of:

"Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE."

Unclear? The fact that it's part of a license does not make it a legal-system-only warning.

The software might eat your dog, and feed your homework. Run it at your own risk, and be prepared to submit patches or fork it to make it behave the way one prefers.

mikestew•12m ago
The software might eat your dog, and feed your homework

Sure, and when it does we can say “this piece of shit ate my dog, and the authors of the software have no concept of a duty of care to their users”. And no amount of “well, axually…” is going to make any difference. I have a hard believing someone is copy-pasting a license file in good faith in response.

timschmidt•5m ago
Most open source software is written by individuals who aren't paid for the effort, and are solving their own problems. Presuming that they feel an obligation to the folks who download and use their work for free seems... bold.

If my neighbor mows my lawn for free, I'm not going to complain about his workmanship. If I want the job done a particular way, the solution is to do it myself, or pay someone to do it the way I like.

InsideOutSanta•12m ago
It's genuinely mind-blowing to me that software can do something obviously bad, someone can point it out, and then someone will link to the license file to say they have the right to do it.

jeremyjh•5m ago

gozzoo•36m ago
> They are open source developers, giving away free software as a gift. There is no duty here.

But actually there is! They didn't start from scratch. They took another very successfull and beloved project with the promise "to make it better". There is some promise here and the duty not to make it worse.

It would be really surprising if they could make it better for literally every user. The perpetual undo is just better handled by git.

"Better" is subjective. They made it better...for themselves. Then gave it away so people who share their opinion, had the opportunity to choose to use it.

This is absolutely true. On the other hand, if there's Vim, Neovim, emacs, MS Word, Google Docs etc and some treat me with respect and others do not, that might affect my choice of which software to use.
Snarwin•35m ago
Sure. And likewise, users who care about backwards compatibility have no duty to do anything for the Neovim developers--they can simply use a different editor that suits their preferences.
JacobKfromIRC•20m ago
Is there a good way to avoid programs like this in general?
boredumb•4m ago
You buy software that includes a commercial license that guarantees data retention
rlue•34m ago
The argument is that developers have a duty not to arbitrarily delete data on your system that you may have relied on that was produced by another program just because they’d like to replace it with something in their own format.

I don’t care if you’re volunteering your time; if you build something whose implied purpose and success depends on other people using it, you emphatically have a duty to those people not to silently destroy stuff that was there before your software was.

pdonis•32m ago
It's worth pointing out that vim is not "another program" as far as Neovim is concerned. It's an earlier version of the same program. Neovim is a fork of vim, not a totally different editor that happens to share part of a name.
goodmythical•25m ago
Forking creates new programs.

If I fork chromium, I do not get to claim that I am a chromium maintainer.

Vim and Neovim are two seperate programs.

SigmundA•11m ago

jeremyjh•6m ago

layer8•33m ago
A duty, like a responsibility, can be something you feel or choose for yourself. The fact that the maintainers of some software don’t feel it is a perfectly good argument for not using that software. There is no necessary connection to compensation or transactional thinking.

mindslight•29m ago
By your reasoning, a doctor who volunteers to provide free care to people has no duty of care to those patients. This is patently absurd - ethics and norms are a large part of what constitutes a professional.

And for what it's worth, I have flagged your comment for the inevitable pointless bickering it has precipitated. While applying reductionist frameworks and seeing where they lead is a necessary part of an individual's path to understanding, please avoid pushing ignorant assertions ("there is no duty here") as if they might constitute well reasoned truths.

sdcfgy•25m ago
There is not a duty but there is an image and quality issue. Something many open source projects suffer from and should not.

And even mentioning that results in "fork it if you're not happy" which immediately turns everyone off who's had to maintain a fork to fix a minor issue in something before. And anyone who can't fork it is being told to go to hell.

Everyone needs to quite frankly get off their high horse, crank the ego down and listen to users. Because you're damaging open source with the attitude.

30 years ago, things were better. They got a lot worse, particularly since github appeared.

HN commenters constantly mistake “what I should do” with “what I am obligated to do.” Nobody is saying open source developers are legally mandated to be careful with user data.

jeremyjh•8m ago
They wrote this software with the explicit intention of offering it to other people to use. Their program deleted data created with a different program, on someone else’s computer. If they have no sense of duty that would preclude doing that, no one should use their software.
