I would like to contribute to open source but I’m not confident enough or understand git properly. As solo dev I only have to fulfill my boss’s standards, they seam to be low.
Yeh, for me git is a backup system.
My boss gave me a hand on some bits (more, I set up a framework and he could tweak pages). Anyway, I fixed some stuff, tidied some of his shit, then trying to get git to merge that back into his workspace REALLY stretched my knowledge of git LUL.
I’m sure doing that every day would get me up to speed, but ATM commit/push means “backup” to me
That’s not advertising, that’s prosthelytizing. Advertising has to be for goods and services. And just telling someone about something isn’t advertising. It’s when you spend money or resources to bring attention to that thing that it counts as advertising. People keep saying that putting a sign on your building stating the company name is advertising. It’s not.
Yes, this isn’t advertising. It’s proselytizing. Advertising has to be for goods and services and it has to be explicit. Me telling you about the company I work for isn’t advertising.
With that, you could sue Google and other companies pushing anti-adblocker tech for discrimination, just bring up all the cases when the supreme court sided with cristofascists to oppress other people.
What should we talk about then, glob patterns (which are NOT regular expressions, for the love of all that is holy and unholy, stop calling glob patterns RE!)
I strongly hesitated saying anything at all b/c there are so very many different rules governing the behavior of every single kind of symbol. Though one jumping off point is the use of the parenthesis, without slashes prior to them and them meaning alternatives within a grouping context rather than merely “remembering”, for the sake of e.g. replacement or copying, so e.g. in the Unix CLI “grep” command this would not work even with the -e parameter (I am not so sure about perl-style though, or rather, this would work within pure perl, but perl-style regexps from within grep is another matter, plus that option itself is not universal across all forms of Unix).
In any case, I hoped that the YoMama joke would be universally understood and appreciated regardless, across all of the many & varied language barriers 😜.
True, but see, all these build up on the theoretical regex. The theoretical regex indeed has only 3 operators: dot for concatenation, pipe for alteration and the ‘kleene star’ [re: Sipser’s]. These 3 operators can express a finite state automata. You don’t really need all that other operators. Read this: swtch.com/~rsc/regexp/regexp1.html Algorithms like Thompson construction can translate a regex to a non-deterministic automata quite quickly, and then from there you can make a DFA or just simulate the NFA.
I would not call PCRE ‘regular expression’ really. If you read the article I gave you it explains why they are mostly a practical utility than a theoretical groundwork. The regex in use today is far from the regex one learns about in books.
I think regex is abused. People use it to parse context-free grammars. Extremely intricate and feature-rich patterns cause people to make mistakes, and end up with security holes!
That being said, I really enjoy NeoVim’s regex. I also like Perl’s. But I would not rely on them for parsing, or even lexing.
Correct me if I’m wrong, but it’s not enough to delete the files in the commit, unless you’re ok with Git tracking the large amount of data that was previously committed. Your git clones will be long, my friend
I don’t understand how we’re all using git and it’s not just some backend utility that we all use a sane wrapper for instead.
Everytime you want to do anything with git it’s a weird series or arcane nonsense commands and then someone cuts in saying “oh yeah but that will destroy x y and z, you have to use this other arcane nonsense command that also sounds nothing like you’re trying to do” and you sit there having no idea why either of them even kind of accomplish what you want.
There are tons of wrappers for git, but they all kinda suck. They either don’t let you do something the cli does, so you have to resort to the arcane magicks every now and then anyways. Or they just obfuscate things to the point where you have no idea what it’s doing, making it impossible to know how to fix things if (when) it fucks things up.
It’s because git is a complex tool to solve complex problems. If you’re one hacker working alone, RCS will do an acceptable job. As soon as you add a second hacker, things change and RCS will quickly show its limitations. FOSS version control went through CVS and SVN before finally arriving at git, and there are good reasons we made each of those transitions. For that matter, CVS and SVN had plenty of arcane stuff to fix weird scenarios, too, and in my subjective experience, git doesn’t pile on appreciably more.
You think deleting an empty directory should be easy? CVS laughs at your effort, puny developer.

Yes it is a complex tool that can solve complex problems, but me as a typical developer, I am not doing anything complex with it, and the CLI surface area that’s exposed to me is by and large nonsense and does not meet me where I’m at or with the commands or naming I would expect.
I mean NPM is also a complex tool, but the CLI surface area of NPM is “npm install”.
So basic, well documented, easily understandable commands like git add, git commit, git push, git branch, and git checkout should have you covered.

What an interesting way to say “git has steep learning curve”. Which is true, git takes time to learn and even more to master. You can get there solely by reading the man pages and online docs though, which isn’t something a lot of other complex tools can say (looking at you kubernetes).
Also I don’t know if a package manager really compares in complexity to git, which is not just a version control tool, it’s also a thin interface for manipulating a directed acyclic graph.
So basic, well documented, easily understandable commands like git add, git commit, git push, git branch, and git checkout should have you covered.
You mean: git add -A, git commit -m “xxx”, git push or git push -u origin --set-upstream, etc. etc. etc. I get that there’s probably a reason for it’s complexity, but it doesn’t change the fact that it doesn’t just have a steep learning curve, it’s flat out remarkably user unfriendly sometimes.
git add with no arguments outputs a message telling you to specify a path.
Yes, but a more sensible default would be -A since that is how most developers use it most of the time.
git commit with no arguments drops you into a text editor with instructions on how to write a commit message.
Git commit with no arguments drops you into vim, less a text editor and more a cruel joke of figuring out how to exit it.
Again, I recognize that git has a steep learning curve, but you chose just about the worst possible examples to try and prove that point lol.
Git has a steep learning curve not because it’s necessary but because it chose defaults that made sense to the person programming it, not to the developer using it and interacting with it.
It is great software and obviously better than most other version control systems, but it still has asinine defaults and it’s cli surface is over complicated. When I worked at a MAANG company and had to learn their proprietary version control system my first thought was “this is dumb, why wouldn’t you just use git like everyone else”, then I went back to Git and realized how much easier and more sensible their system was.
No it wouldn’t. You’d have git beginners committing IDE configs and secrets left and right if -A was the default behavior.
vim, less a text editor and more a cruel joke of figuring out how to exit it.
Esc, :, q. Sure it’s a funny internet meme to say vim is impossible to quit out of, but any self-respecting software developer should know how, and if you don’t, you have google. If you think this is hard, no wonder you struggle with git.

Just because you don’t like the defaults doesn’t mean they don’t make sense. It just means you don’t understand the (very good) reasons those defaults were chosen.

Git’s authors were the first users. The team that started the linux kernel project created it and used it because no other version control tool in existence at that time suited their needs. The subtle implication that you, as a user of git, know better than the authors, who were the original users, is laughable.
No it wouldn’t. You’d have git beginners committing IDE configs and secrets left and right if -A was the default behavior.
No, you wouldn’t because no one is a git beginner, they’re a software developer beginner who need to use git. In that scenario, you are almost always using repos that are created by someone else or by some framework with precreated git ignores.
You know what else it could do? Say “hey, youve said add with no files selected, press enter to add all changed files”

Dumping people into an archaic cli program that doesn’t follow the universal conventions for exiting a cli program, all for the the goal of entering 150 characters of text that can be captured through the CLI with one prompt, is bad CLI design.
There is no reason to ever dump the user to an external editor unless they specifically request it, yet git does, knowing full well that that means VIM in many cases.
And no, a self respecting software developer wouldn’t tolerate standards breaking, user unfriendly software and would change their default away from VIM.

Lmao, the idea that we should hero worship every decision Linus Torvalds ever made is the only thing laughable here.
I think in this case, “depth” was am inferior solution to achieve fast cloning, that they could quickly implement. Sparse checkout (“filter”) is the good solution that only came out recently-ish
Lol if an employer can’t have an intelligent discussion about user friendly interface design I’m happy to not work for them.
Every interview I’ve ever been in there’s been some moment where I say ‘yeah I don’t remember that specific command, but conceptually you need to do this and that, if you want I can look up the command’ and they always say something along the lines of ‘oh no, yeah, that makes conceptual sense don’t worry about it, this isn’t a memory test’.
These things are not related. Git uses the system default editor, which is exactly what a cli program dropping you into an editor should use. If that’s Vim and you don’t like that, you need to configure your system or take it up with your distro maintainers.
No, it should prompt you to enter your one sentence description in the CLI itself, and kick you out to an editor only if you provide a flag saying you like writing paragraph long commit descriptions.
Git is complicated, but then again, it’s a tool with a lot of options. Could it be nicer and less abstract in its use? Sure!
However, if you compare what goes does, and how it does, to it’s competitors, then git is quite amazing. 5-10 years ago it was all svn, the dark times. Simpler tool and an actual headache to use.
What are you smoking? Shallow clones don’t modify commit hashes.
The only thing that you lose is history, but that usually isn’t a big deal.
–filter=blob:none probably also won’t help too much here since the problem with node_modules is more about millions of individual files rather than large files (although both can be annoying).
git clone --depth=1 <url> creates a shallow clone. These clones truncate the commit history to reduce the clone size. This creates some unexpected behavior issues, limiting which Git commands are possible. These clones also put undue stress on later fetches, so they are strongly discouraged for developer use. They are helpful for some build environments where the repository will be deleted after a single build.
Maybe the hashes aren’t different, but the important part is that comparisons beyond the fetched depth don’t work: git can’t know if a shallowly cloned repo has a common ancestor with some given commit outside the range, e.g. a tag.
Blobless clones don’t have that limitation. Git will download a hash+path for each file, but it won’t download the contents, so it still takes much less space and time.
If you want to skip all file data without any limitations, you can do git clone --filter=tree:0 which doesn’t even download the metadata
Yes, if you ask about a tag on a commit that you don’t have git won’t know about it. You would need to download that history. You also can’t in general say “commit A doesn’t contain commit B” as you don’t know all of the parents.
You are completely right that –depth=1 will omit some data. That is sort of the point but it does have some downsides. Filters also omit some data but often the data will be fetched on demand which can be useful. (But will also cause other issues like blame taking ridiculous amounts of time.)
Neither option is wrong, they just have different tradeoffs.
See this is the kind of shit that bothers me with Git and we just sort of accept it, because it’s THE STANDARD. And then we crank attach these shitty LFS solutions on the side because it don’t really work.
What was perforce’s solution to this? If you delete a file in a new revision, it still kept the old data around, right? Otherwise there’d be no way to rollback.
Yes but Perforce is a (broadly) centralised system, so you don’t end up with the whole history on your local computer. Yes, that then has some challenges (local branches etc, which Perforce mitigates with Streams) and local development (which is mitigated in other ways).
For how most teams work, I’d choose Perforce any day. Git is specialised towards very large, often part time, hyper-distributed development (AKA Linux development), but the reality is that most teams do work with a main branch in a central location.
The best part is, unless that function name is misleading, it doesn’t matter how the data is passed; a copy is being sent out over TCP/IP to another device regardless.
Force with lease will send up what your local thinks the most recent commit on the branch was and the host will reject the push if it knows of a more recent commit on that branch. Basically, it saves you from overwriting a commit you didn’t realize existed.
