Pijul was started out of frustration that no version control system was at the same time fast and sound: The context and motivation are irrelevant. TLS has client certificates, and I actually have used them for authentication before. This is absolutely bogus. Please correct me if I have! And need to have a custom server and protocol. Of course it does. I've done this many times, e.g. > Therefore, if after reading this post, you independently rediscover the algorithms presented here, that’s ok, but you must still license your “independent rediscovery” under the Gnu GPL-2.0 license, and cite the sources (for instance this post). > GPL on the other hand doesn’t have an expiry date. 1. pijul init creates a pijul repository, much like git init or hg init. It's not something likely possible to do automatically and doing it manually is just extra work that is probably for nothing. Since April 2017, Pijul is bootstrapped, meaning that we use it for its own development. I've been keeping an eye on Pijul for a while, but assumed that (when it eventually stabilised) it personally wouldn't be worth the effort to switch from git. The easiest plugins to write would be s-expressions and JSON, and I could definitely see myself choosing Pijul for such repos in the future. :-), Thanks for Pijul; I'm super-excited about the possibilities. Nope, I don't do crypto, I wouldn't work on other stuff if I did. return 1 + 1 + 2; and a patch C based upon B changes that to: All tooling could deal with this rather than the text of the source code. Fortunately, pijul commands have pretty close analogues inother VCSes. I've also seen partial reimplementations of Pijul, from the source code, with a different license, which is absolutely clear. Yes, it does, even if the interface might be somewhat lacking, and the documentation work in progress. viewing diffs, bisecting to pin down a bug, etc.). Note that you could implement a Token or AST aware merging strategy for git as how you merge is an implementation detail that is not encoded into the repo. tux0r - have you written any posts on Pijul or Darcs? Does that make working with it harder ? I thought I'd use branches or unrecord to simulate the scenario I laid out but I could only figure out how to create branches but not switch between them (the checkout command seems to have been removed) and unrecord seemed to not only not revert files to their former state but I could not reapply the patches later with pijul apply. I do love git, and I think its simple mental model of content addressed commits and trees is fantastic. Bonus question: I'v never seen the notation "[0,n[" to represent a half-open internval before (I've seen "[0,n)"), but it does have a certain logic to it! That's some A level chicanery. Not my cup of tea either. Well, I think I have it installed (via brew), and the .dylib exists, it's just that doesn't have the spcific mangled symbol Rust is looking for inside the library. Darcs is the "smart" to git's "dumb" and Pijul is exploring if you can have "smart" without sacrificing "fast". Why develop my own extension instead of contributing to the existing one? Pijul is a free and open source (GPL2) distributed version control system. I find it sad to see that Atlassian does not advertise their own support for Mercurial. Would I want to put myself at legal risk, just because I want to try an experimental VCS? best. However, unlike Darcs, which operates on changes only, Pijul … I think it would be really interesting to see a fresh perspective on what else is out there in the VCS world, and it would be a nice chance to highlight what non-Git source control systems bring to the table. I guess it doesn't matter as long as it works /shrug. > Doesn't Cargo depend on being able to 'git clone' software for it to be installable? I predict that once it gets popular, in common usage it will be shortened to 'pij' (and derivatives). … Pijul/Any is written in Rust. If not, you totally should! I just tried to go there again and the page is offline. Perhaps someone who knows more about licensing that me can elaborate? Is this project still going or is Anu the future? 2. the whole merge/rebase dichotomy. Compare Darcs vs Simul Docs. In other words, Pijul works in polynomial time for all patches that systems other than darcs know of. Pijul/Any is written in Rust. The biggest problem IMO is that Pijul is more similar to git rebase than git merge. The project seems very interesting, > cargo install pijul --version 1.0.0-alpha, (needs some native dependencies like zstd). It would be nice to have for other languages too (C, Python, etc. They make the claim that cherry picking "just works" but I think this misses the big picture. It's a widespread conflation, but thankfully it's easy to sort out; for example, The Canterbury Tales was written before copyright existed, but that doesn't mean I can claim it as my own work; that would be fraud (specifically: plagiarism). tux0r - have you written any posts on Pijul or Darcs? > On a quick glance, that seems (?) That's fine I suppose, but my fear is that this current approach is that the existence of this project simply acts as an impediment for truly motivated people to work on the next generation VCS. Pijul's cherry picking only "just works" with respect to merging lines of code. No big deal from my perspective. Pijul for VS Code is an extension for Visual Studio Code which adds integration with Pijul as a source control management system. Now it seems completely natural. Still a tiny fraction compared to available tokenizers in Pygments: Encoding a generic, potentially versioned AST in S-expressions seems feasible. Machen ein rust docker container $ docker run -it -v “$(pwd)":/src –network host –name=rust1 rust:latest … Semantic/format-aware versioning would be really nice. You can totally do that in Pijul by adding extra dependencies, and moreover, this is like saying `git rebase` adds very little value to Git. This is not what I meant, it's just a commented targeted at a number of different people who have stolen my stuff in recent years, in different areas of my work, and not only about Pijul, genuinely claiming to rediscover it after they had read the code, read the papers, asked me questions about it. There are many git users, most of whom … Featuring nest.pijul.com. > It is actually the exact opposite: Git forces you to reconsider those conflicts (there's even `git rerere`), whereas Pijul only shows you the unresolved conflicts. I'm not sure what you mean. Consider some changes from A to B: A semantic-aware diff could do better. > someone submitting stolen work to a fellow he stole the work from. Has any1 had success compiling it on mac? One advantage to using a syntax highlighting tokenizer/lexer is that they are designed to be fast (many of them need to be real time in text editors after all), and handle "degenerate cases" very well (text editors spend a lot of time on work in progress code that doesn't fully describe a complete compilable unit; version control systems just as well need to be good at storing work in progress states). Ich wollte es versuchen aber ich nicht hatte rust. Previous message: [darcs-users] darcs news #112 Next message: [darcs-users] plans for Darcs 2.12 Messages sorted by: Dear Hackers, The 11th Darcs Sprint, organised by and jointly with the Pijul team, will be in Helsinki, on Friday May 6th-Sunday … (Why just the other week there was an HN headline where someone was really excited they hacked the email-focused `git format-patch` and a workflow akin to sending email to oneself to replicate `git add --patch` because they didn't realize `git add --patch` was also a built-in tool.). That page has always been dog slow. Work in progress. Got surprisingly good results from what I tested. Once a conflict is solved in Pijul, it's solved by a patch, and solved forever. Darcs' patch theory is centered around patches, with two primitive operations, commutation and inversion.Compared to this, pijul's theory revolves around files (i.e., states of the working directory at a given point in time) as well as patches, with a merge operation between patches. Git could learn from Pijul, IMHO, in the sense of better emphasis for newcomers for how to think in terms of patches. I would love to see what the future holds! https://en.wikipedia.org/wiki/Islamic_Jihad_Movement_in_Pale... Well, at least it didn't change the name to another (than 'Anu') ancient god : Isis ! Yes, that’s a subtlety that my original comment didn’t address. There's still plenty of room to explore possible new VCS possibilities, just as we continue to explore things like programming language possibilities. I've been asked to review results of mine in the past, taken form arxiv.org and resubmitted by senior academics. While Pijul currently doesn't support binary files, plans call for it to do so soon. > - As BlackFingolfin pointed out, the blog post has a "Warning about licenses" at the top. "Fast" is the primary reason people pick Git over the competition. That's a patent, and I do think that there exists papers that describes patented algorithms. I haven't looked at darcs in many years, but it would be unsurprising if it had evolved to similar generality like pluggable byte ranges. Apart from speed, we are also interested in a better way of handling conflicts between patches, which is also something that Pijul … Pijul 0.3, our first bootstrapped release! You will also get a good … Doesn't Cargo depend on being able to 'git clone' software for it to be installable? I’m unsure how git and darcs do that, but I suspect it requires some heuristic or … Thanks again & wishing the best for Pijul. But given that many areas of scientific inquiry are highly specialized, it isn't particularly surprising that if you rip off someone's work, that someone is going to be picked as a reviewer for your paper by chance. The gpl doesnt protect ideas, it only protects code. [darcs-users] Pijul 0.1 Florent Becker florent.becker at ens-lyon.org Thu Oct 1 17:27:16 UTC 2015. I came up with that name, but to be honest, I was more interested in getting stuff to work (which was challenging enough) than in thinking about names at that time. See tompazourek's message for quote or visit: I'm the author. Zunächst mit Docker Das ist langsam für schnell Sie brauchen ein Dockerfile. Have you ever read a math/CS paper that attempts to dictate a license on all future work based on the algorithms (or ideas in general) within? For example, it's common for git to mix up function definitions by fixating on common lines (e.g. You should keep your work closed source and figure out a way to prevent others from stealing your work from you before making it open source. Re sibling that links to author’s tweet: plagiarism is something else entirely, and I fail to see how GPL helps in combating plagiarism. Git has no notion of files, but this is how Darcs does it. Each line belongs to a patch and it can depend on the diffing algorithm which patch owns a particular line. However I do often find myself annoyed by the lack of a "change" concept other than the immutable commit. I just tried to go there again and the page is offline. Copyright does not protect ideas. I'd be very interested to experiment further with it now that one of the patch algebra VCSes has finally adopted a "chunk" option. The snapshot model is fundamentally different and doesn't require resolving conflicts in the same way. [1] https://github.com/WorldMaker/tokdiff, (ETA: Suppose the first step is that it is time to get the band back together and update the prototype to Python 3.). I think it would be really interesting to see a fresh perspective on what else is out there in the VCS world, and it would be a nice chance to highlight what non-Git source control systems bring to the table. > Have you ever read a math/CS paper that attempts to dictate a license on all future work based on the algorithms. I'm really excited to see what Pijul ends up doing. I don’t trust their hypothesis that “it is impossible to get the same inode twice”, I believe this strongly depends on the filesystem. Ah yes, the eternal challenge of "Naming things". I believe the Unison language [1] does this for their code storage system. I still drop into the git CLI if I need to do things like editing the contents of lines, e.g. Pijul is like rebase in that it forces you to consider the full history of all the patches in a set which requires to resolve arbitrary conflicts. Even though Git is already pretty great in my opinion, there's always stuff that can be done better. > - The project got renamed to Anu. And distribute that by default as well, otherwise everyone defines their own mutually incompatible aliases. * The contents of packages are not acquired by doing a git clone; source code is stored in an S3 bucket, and Cargo downloads it directly. Without reference to the source language, the most native rendering of this based on spelling definitely has short vowel sounds. If you wish for an effective Version Control Systems product for your enterprise you need to take time to assess different solutions. In fact, making an s-expression plugin which is robust across various Lisp dialects might be a good way to bootstrap the user community. I've seen sleazier academics just CnP things without attribution. pmeunier on November 15, 2020 . I haven’t met a single person that used manual git patches in my entire career (10+ years, web services). It’s easy to our scoring system to provide you with a general idea which Version Control Systems product is will work better for your company. return 1 + 1 + 1 + 1; and a patch B based upon A changes it to: The benefit of resolving those conflicts is that it can help with cherry-picking, but I don't want to be doing this work all the time for an incomplete solution to a rare operation. Even though I don't think that's how the GNU GPL works, it's already a big motivator for me to simply close that tab. Etc. It takes multiple seconds for that page to open, and then it shows me "Not found". 2. pijul add tells pijul that it should start tracking a file, much like gitadd or hg add. > Is the website fast and inviting? It seems that this results in review tools bending backwards to add that on top and it makes backports and other cherry-picks harder to follow. Also, merging (especially automatically) is limited by the quality of the data. At the same time, … In addition, there’s no implicit patent, you have to apply in every jurisdiction where you want to protect your idea, and IIRC in most jurisdictions you either can’t retroactively apply for a patent after you’ve published the idea, or you only have a short period after publishing before the right is forfeited. IOW, git already has the freedom to use a merging strategy that understands tokens or AST since it is not hard-coded into the repo encoding. To merge things, we have to find a common ancestor and reconstruct the changes made in … Each commit represents the state of the repository at a particular time. Git is a snapshot based model and so doesn't leak any implementation details about patches themselves.
