Is git really far worse technology than mercurial? I’ve used both for years and to be honest they are pretty similar. What important capabilities does hg have that git does not? Maybe you can argue that hg is more ergonomic, but that’s just polish it doesn’t mean the tech is far better…
> Is git really far worse technology than mercurial?
Git is far worse simply because of "staging". "Staging" may be necessary (I do not concede this) in big projects, but in small projects it's an absolute disaster to the mental model. Most people on small projects just want "checkpoint the current code in my directory and put a comment on it".
In addition, Git's UX is hot garbage. I would constantly be doing rsync on git repos before any operation that is slightly weird knowing that I may put the repo in some state that I cannot easily unwind. I never did that for Subversion. I never did that for Mercurial. I don't do that for Jujutsu. Those are all sane UX.
Side note: Thankfully AI is REALLY good at telling you how to un-wedge your git repo. That should tell you everything you need to know about Git UX and why you should avoid Git.

Interesting, that's definitely not how I use git. My current code is rarely in a shape that can be fully committed. It often contains additional stuff I did on the way (small bug fixes, TODO comments, debug printf statements, etc.) that I don't want in the commit. Very rarely do I type `git add .` Am I the exception?
People make this claim but it never made sense to me. How do you know the version that you are committing is buildable if you never tried building with it? And if you tried building with it, you can just do `git add .` at that point.
So yes, your usecase does not make sense to me.
There was another comment that said similar thing...

But it is "dead" for some reason...
Same. I absolutely don't use git for snapshotting what I'm currently doing. That goes both for work and for my numerous hobby projects. I always cultivate commits so that they're focused on a single type of change or feature, and then the next commit is typically something which uses that feature, etc. I don't mix in whatever else I'm doing - be that whitespace changes, update comments elsewhere, or other features I'm working on. This helps tremendously when (as I do) I leave my hobby project for a while and then I come back months (or sometimes years) later. And, both for work and for hobby stuff, if I want to add something, e.g. support for a new function, and I had done something similar in the past, it's easy to look at the particular commits about that from the past, and I can see that I need to update this, this, and this file so-and-so, and with these kind of changes. I don't have to wonder about what belongs to this feature and what doesn't.
Oh, and I use git add ---patch almost exclusively. It's rare that I just do a "git add". I'm building up my stage, I'm checking it, I'm fixing it (if I accidentally stage something which doesn't belong), then I commit.
Having done it like this for a great many years I'm benefitting from it all the time. I can look at all my hobby projects (looking at the commits), and I'm back in where I left off, and I see excactly what I was doing back then (which, obviously, I wouldn't be able to rembember otherwise).
CVS though.. that was harder to do right. So a lot of stuff became just snapshots. You had to plan much more carefully. And then there was SCCS before that.. and before that again, well. Manual "keep two versions" svc.
My use of `git add` - and the explicit staging area more generally - is mostly a workaround for the fact that the repos I work with have checked-in dev setup scripts, IntelliJ/Visual Studio/Xcode/VS Code configurations, and so on.
My own setup differs in slight ways from what those scripts expect, and even where they match I like to do my own customizations. I don't want to commit those changes, and staging makes it easy to not do that MOST of the time. The rest of the time, it's a `git stash` dance, which I sometimes screw up and lose the customizations.
I've tried to manage the configurations a different way, such as by having a private branch with my own settings checked in, but that doesn't usually work out. I'm aware that the REAL problem is that my coworkers have checked in those settings to begin with, but I would counter-argue that the REAL REAL problem is that those tools don't have a good way to combine "settings that I override or that only I care about" and "settings that have project-wide defaults but are safe for me to override." (Visual Studio gets it close to right with its .xyzproj and .xyzproj.user files, but VS Code's single .vscode/ folder breaks down in shared repos.)
I'm with you. My current code is a superset of the task I'm trying to accomplish, test code, leftovers from experiments, etc. I often have to break it up into logical chunks that get merged separately. I tried the jj flow and it's just not my thing. Git matches my mental model exactly, but I used it second (after subversion) and in my most formative years as a developer. Maybe there's a universe out there where things worked out differently.
I don't see why there has to be a special staging area when you could just edit the HEAD commit instead. In git you could do "git commit --patch" to commit selected parts and then add more changes to the HEAD commit by "git commit --patch --amend".
The way I do things is that there is no such thing as a shape that can't be committed. Committing is just like saving. It's fine to commit haphazard checkpoints and all manner of crazy stuff. You can use tags or merges or whatever to indicate that something is "done" but for me those kinds of commits are the exception, not the norm.

Supposedly, Meta has the data to support the claim that you (and I) are the outliers here. Staging is confusing to users, especially new ones, which is why jujitsu explicitly doesn't have staging.
The reason jujutsu doesn't have staging is that staging is incompatible with concurrency. The UX is a happy coincidence.
Apparently the world went dumber in the last 20 years and staged commits are DIFFICULT now.

With “git reflog” and “git reset” or “git checkout” one can undo any series of ill conceived squash/rebase/amend operations. There’s actually no need to rsync the work area in advance.
Try doing the same in any other source control system…

On the off chance that you haven't already had this suggested to you on HN, I would suggest taking a look at JJ.
I use it in all my Git-underneath repos with `jj git init --colocate` (You can run that in a git repo and it will hybridize, or in a new folder and it will init and hybridize).
It doesn't have the staging concept, treating the working copy as just another commit (@), and to boot it snapshots the state of the tree into @ when you run any jj command, so you can use `jj op log` to see every intermediate state of your working copy at any time.
Commit is just `jj commit` with no staging mechanics, or `jj split` to 'split the working copy commits' (commit some, keep the rest in @).
I'm already a quite happy jj user, but thanks for the recommendation. :)
I often want to "save" but not have a comment, and not ready to make it a clean commit that I want a comment on. That's when I stage, then I can see the diff and revert still. But ya, maybe I could adapt to not worrying about having a million commits instead of clean ones at points that make sense with good comments.
You can add everything and commit all at once in git, so you’re technically using staging but it doesn’t feel like it.
I stopped using it the first time I committed something I didn’t want to, over a decade ago, haven’t used it again since so I forget the exact invocation, but I think it was just “-a” or something.
Before it bit me though yeah, that did seem like a default I’d have preferred. Not any more.
> Not any more.
`git add -p` FTW
Mercurials lack of not permanent branches early on with the bizarre "we have a plugin for that" way of doing it showing up too late to change the decision
not to mention the early "just clone it into a new dir" answer before lightweight branching ...
I haven't lost data to git in a long time and I never rsync anything. But it took a long time to get to that point.
Git is extremely predictable, but only after you thoroughly understand it. Until then, it seems to surprise you often and every time it happens you think you've lost data. Many times I've had collaborators who said "git ate my files" and I can usually get their files back in a few minutes. This makes them hate git because they cannot use it without having me on call, and they cannot be bothered to learn git thoroughly themselves because it's too damn hard.
I've always felt bad about not understanding git better and wanted to dedicate time to learn it properly but never got to it. Finally this is a use case where AI is really good. It has always been able to get me out of trouble when I mess up, and often rescued files I thought I had lost for good. And is always able to rebase for me, normally a place where I flail pathetically. And it's easy to human verify the result before pushing.
Honestly this is one area I really like AI - so I can focus on the things I really need to focus on and not spend a bunch of time becoming an expert in things I don't want to be an expert in.
I'm curious on the use of rsync in version control. What's the source and destination?

I find staging useful even in small projects. I've been deliberately experimenting with jujutsu for the past year or so in various projects, and one of the workflow differences that I noticed most readily with jujutsu was the lack of a staging area. It took me a while to get used to that.
