> One common criticism we’ve heard since we started Pijul a few years ago was about the name. return 4; I do think they might want to go with something shorter (pi?) To me it seems little more than a hobby project of someone with an interest in version control systems. Machen ein rust docker container $ docker run -it -v “$(pwd)":/src –network host –name=rust1 rust:latest … Their claim is simply incorrect. I'm the author, and I'm entirely guilty of that misunderstanding. Code ; Changes ; Discussions ; CI #308 Add a rollback subcommand. Pijul’s architecture and design methodology was influenced by the Darcs project, which we covered in detail here.. One distinctive feature of Pijul (shared with Darcs) is change commutation, whereby changes that could be recorded independently can be applied in any order, without affecting the result.. I've also seen partial reimplementations of Pijul, from the source code, with a different license, which is absolutely clear. It's a lot of characters to type all on the right hand (in QWERTY). The sound distributed version control system . And being plagiarized totally sucks, as someone who has found his own GPL'ed code in non-open commercial products, I think I can relate, even though this is of course not quite the same. 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 haven't worked with Pijul yet. Is the software easy to install? You will need nix to run them. Nah, Atlassian does only what makes sales go high. > 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. I would love to see what the future holds! Sure, it's awesome if those tools can host themselves, but what about being able to set it up quickly? Fixing two bugs around conflicts on the last line, where invalid patches were produced (first bug) and applied (second bug) If not, you totally should! Hence there's not many darcs users left for which pijul would be a no-brainer. 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. Once a conflict is solved in Pijul, it's solved by a patch, and solved forever. 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. Can we still default to lines ? i’ve had my eye on this project for a few years, though only from the sidelines, but now’s the time to truly take the dive! Alright, maybe you should have read my answer before replying. ), but they'd (a) be more complicated and (b) more subject to churn. I think a particular part of the problem is to get the diff algorithm to match parentheses correctly. Also all documentation is 404. Until there are packages in linux distributions, you can get it with `cargo install pijul --version 1.0.0-alpha`. Do you know, that calling someone a git is an insult? Why develop my own extension instead of contributing to the existing one? > Is the website fast and inviting? 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. And distribute that by default as well, otherwise everyone defines their own mutually incompatible aliases. Pijul's cherry picking only "just works" with respect to merging lines of code. Which is valid. Let's say I have a local git branch with 10 commits on top of master. It is actually targeted at a particular species of academics, who have been quietly republishing my work in recent years, and not only my work on Pijul. spreading data and parentheses across multiple lines to work better with line-based tools like git, or keeping revisions in the files themselves, etc. What's going on there? Pijul can even postpone downloading content that has been deleted since a change was created. I don't think this is true. The idea of Pijul came while Florent Becker and myself were writing a paper on self-assembly. Thanks! The "universality" of tokenizers is tough to beat, and though the tokenizers seem "dumber" than parser brethren, it's at a nice maxima for "good enough" for things like character-based diffs. Let's say I have a patch A that adds a line: They only say that it is difficult because of all the interoperability issues they keep discovering. The winner is the one which gets best visibility on Google. But I recommend everyone to spend half an hour with it. I'm not sure what you mean. > Have you ever read a math/CS paper that attempts to dictate a license on all future work based on the algorithms. For a time, I was tracking some of them to figure out which ones support which particular protocol extension; the result is https://ssh-comparison.quendi.de and the list there is really incomplete (and sadly also outdated -- PRs welcome ;-)), I think I could easily double the number of entries there if I resumed work on it. I've done this many times, e.g. I remember when the iPad first came out the whole internet was going on about what a terrible name it was. Big problem on Git in game dev, is the fact that you often don't want to download everything. (Unlike many HN commentators, who are too trapped inside the git way of thinking to realize its limitations ;-). I know a lot of people feel like Git has "won", but I myself have a soft spot for Mercurial, and I think having competition is essential to innovation in the space! The author seems to be referencing a project of theirs with a Finnish name, so perhaps my intuition as a native Finnish speaker can help. As I … return 1 + 1 + 1 + 1; and a patch B based upon A changes it to: As a person who carefully listens to HackerNews and Twitter comments for life advice (as one should), I decided to revert that move. Can someone help me find a more flattering way to pronounce this project? 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. In contrast with git, this merge operation is well-defined and has all expected … It could track, e.g., symbol renames very early on in darcs' history. At some point I've even been asked to review papers claiming to prove my own results. > That's actually the case, because you can totally simulate Git using Pijul if you want, except for the weird merges where Git shuffles up lines randomly. If you're not sold after that, you never will. Without reference to the source language, the most native rendering of this based on spelling definitely has short vowel sounds. There seems to be no way to simply rollback a change if some newer change depends on it (so we can’t use unrecord). EDIT : Oh crap : I agree that there is rampant theft going on in open source. The funny thing about names is whatever they are, you end up getting used to them. > it can not track things like "This calls a function introduced in patch X" which makes the cherry-picking functionality of very little value. 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. Pijul is a draft of a prototype of an implementation of Samuel Mimram and Cinzia Di … TLS has client certificates, and I actually have used them for authentication before. I know you've been open about working with/from "ideas/people" in the darcs community, and good about the shoulders [1] the pijul work stands on/improves, and I also dislike people not giving credit where it is due. Thank you for clarifying this, I think it's much better if this paragraph doesn't distract people from the great work you are doing on Pijul. share. First 'Linux', now 'Git'". https://discourse.pijul.org/t/build-failure-on-macos-zstd-se... https://en.wikipedia.org/wiki/Interval_(mathematics). 3 years ago. pmeunier on November 15, 2020 . You should read the other comments made after yours... apparently that was just a misunderstanding and not what the author intended. There are multiple ways to do it, e.g. [darcs-users] Pijul 0.1 Florent Becker florent.becker at ens-lyon.org Thu Oct 1 17:27:16 UTC 2015. 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. One property you might want would be that, in some sense, parentheses would always remain balanced. return 1 + 1 + 2; and a patch C based upon B changes that to: … I don’t want to write a full pijul tutorial here, but I do need to mentionthe basic commands if you’re to have any hope of understanding the restof the post. I have some private code on Darcshub though. [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.). What they're looking for is a patent, not copyright. Wait few years until we finish new shiny graphical UI first! Pijul's whole setup seems like it would solve a bunch of problems I have with git. You would need cargo to compile it from source anyway. I explored this idea back in the day with darcs (though I don't think darcs' proposed character-based patch format "chunks" ever made it past the proposal stage), as some back and forth discussions led me to what I think is a perfect compromise on power, time (to compute), and universality. I think, it's less this, and more preventing others as passing these ideas as their own. Re sibling that links to author’s tweet: plagiarism is something else entirely, and I fail to see how GPL helps in combating plagiarism. 2. pijul add tells pijul that it should start tracking a file, much like gitadd or hg add. "Fast" is the primary reason people pick Git over the competition. We’ve not yet thought all the theory of this through, but it might be added in the future. Hi darcs fellows, Florent Becker and myself are proud to announce the second public release of Pijul, a new version control system aiming to be easy to learn and use, distributed, and fast. That is clearly not what I meant, and I'm deeply sorry about this. But I’d be excited if someone figured out how to do it. The Nest used to be really fast with the previous Pijul, but I remember the first iteration took a few days of debugging under full load before being stable. With you every step of your journey. Copyright does not protect ideas. I do work in the area of data storage myself. I only looked into Darcs and Pijul for the first time a few weeks ago, and I'm not entirely onboard with the whole mindset of your repo being nothing but a set of patches. if I've added a new function and renamed an existing one, and I want to add these as two commits, I might edit the first commit to use the old name. Running the integration requires orchestrating a few different repos (darcs, pijul and sanakirja), as well as setting up the right environment and applying some WIP patches. Git, Mercurial, and Fossil are probably your best bets out of the 14 options considered. Sure, but then you can't use your existing ssh credentials. Merging is only one aspect of version control. Negative Marketing. One great use-case for git patches is moving files between repos without losing their history. Just wanted to say that the Magit UI makes it really easy to pick and choose which lines to commit (plus it has code-folding for files and chunks, which is nice). It looks like you don't have libclang. save. Etc. I'm not angry at all! Honestly, the whole faffing around with the name leaves me with a very bad taste in my mouth. This thread is archived. Pijul is a free and open source (GPL2) distributed version control system. The project seems very interesting, > cargo install pijul --version 1.0.0-alpha, (needs some native dependencies like zstd). Each commit represents the state of the repository at a particular time. Its distinctive feature is to be based on a sound theory of patches, which makes it easy to learn and use, and really distributed. tux0r - have you written any posts on Pijul or Darcs? I see many newcomers finally get their "AHA" insights about git's power when they learn `--patch`. The diff algorithm, acting on lines, is pretty generic in Pijul, but there is a crucial and nontrivial pass after that, to get from a line diff to a graph diff. Hoping the author reads this. In Finnish you’d likely pronounce pijul [pi-jul]. The finished prototype I built created standard character-based unidiffs, and it sounds like could possibly be slotted directly into Pijul now. To clarify: they claim that after reading the article, any independent implementation of the algorithm (even if it didn't involve looking at their code) must be licensed under the GPL. It is not a drawback at all, there are no downsides to it, and we get the very serious benefit that merges are associative, which is not the case in Git. Please correct me if I have! * You can have your project depend on a package that lives in a git repository, but you cannot upload a crate to crates.io that depends on a git repository. There's still plenty of room to explore possible new VCS possibilities, just as we continue to explore things like programming language possibilities. Pijul being based on patches encodes patch information into the repo. (Or the vast number of TextMate grammars in the wild, such as editors like VS Code have standardized on.). I'd love to give it a try again the latest (v0.12.2) release, but: > I cannot find an issue tracker. - The project got renamed to Anu. Compare Simul vs Darcs. I find it sad to see that Atlassian does not advertise their own support for Mercurial. Work in progress. SCORES FEATURES PRICING PRICING MODEL INTEGRATIONS. 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. Git has no notion of files, but this is how Darcs does it. Once a conflict is solved in Pijul, it's solved by a patch, and solved forever. 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. It takes the vowel sounds of “sit ghoul”. I propose the addition of an option --negate (alternatives: --invert or simply --untracked) to pijul ls to show a list of all untracked files instead of a list of all tracked files. I suppose these days tree-sitter would be one way to support a lot of languages at once (. I find it sad to see that Atlassian does not advertise their own support for Mercurial. > someone submitting stolen work to a fellow he stole the work from. 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. Hm, right at the start in the "Warning about licenses" they seem to try to make the GPL apply to a concept, an abstract algorithm -- kinda like a patent? I even made some test repos in both Git and Pijul to verify that Pijul forces you to resolve conflicts that three-way merge doesn't care about. However according to this post that has now been resolved which is fantastic news. Hello, We've just released Pijul, a distributed version control system based on patches, with the goal of being as easy to use as darcs, without the performance issues.. 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. Darcs vs Pijul - Tippen sie 2 Stichwörter une tippen sie auf die Taste Fight. At the end of the article it says that the rename (to Anu) has been reverted. It was just a reaction to a number of plagiarism events that have happened to me in recent years. Features. What I mean is that it forces you to resolve conflicts that you probably wont ever care about. Pijul/Any is written in Rust. Got surprisingly good results from what I tested. There’s no way I’m ever going to be typing pujil, no wait pijul, any amount of times during my daily work. Feels like a version mismatch or something. Doesn't Cargo depend on being able to 'git clone' software for it to be installable? The Nest is still experimental (which explains the downtime), but you shouldn't need to sign in order to view any code there. > Doesn't Cargo depend on being able to 'git clone' software for it to be installable? Sure, it's awesome if those tools can host themselves, but what about being able to set it up quickly? [1]: https://en.wikipedia.org/wiki/Interval_(mathematics). > GPL on the other hand doesn’t have an expiry date. * 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. I do this so infrequently that I never remember the commands, but frequently enough that I remember which StackOverflow answer to Google for: https://stackoverflow.com/a/11426261/884682, That's not a good vision for the future ;). I was just explaining my cautious wording. 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 agree with the above poster that if graphical user interfaces prioritized it better, if the CLI had a bit fewer warts (I still often confuse when to use `git add --patch` and when to use `git add --interactive` though it isn't an awful confusion because you can get to one from the other when you remember how to use it), and if tutorials tried better to train people on the tools that already exist, a lot more people would presumably use them (daily in some cases). 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. > - The project got renamed to Anu. Es ist gut denn hat es associtive patches. For one, it seems really hard for a casual user to understand what's really going on, and secondly, (I'm sure there's tons of arguing over this online already) it really fuddles the history of a project. Pijul was started out of frustration that no version control system was at the same time fast and sound: News of Sanakirja. > This is a big drawback and so we should hope to get some serious benefits to make up for it. Yeah, they are basically claiming patents on the ideas presented. However, even patents can’t be licensed in perpetuity, so they can’t possibly apply to all future work. No, I have not written anything about Darcs (yet? Other users might see a different result if they "git show" your commit if they have a different diff algorithm configured. It takes multiple seconds for that page to open, and then it shows me "Not found". Compare Darcs vs Simul Docs. darcsden 1.2 beta built Jun 23 201810:48:19; report problems to simonsimon Considering how much time one spends swearing while trying to resolve issues with version control, I think. 1. that a commit maintains its own identity when cherrypicked onto another branch, and its intrinstically linked. Anu was at least pronounceable without doing a few double takes. Next message: [darcs-users] new darcs maintainer: Guillaume Hoffmann Messages sorted by: Dear darcs acolytes, Pierre-Étienne Meunier and myself are honoured to present version 0.1 of Pijul. My idea that I’ve bandied about here a few times would be to create some kind of a semantic database (not based on relational algebra). Nope, I don't do crypto, I wouldn't work on other stuff if I did. tux0r - have you written any posts on Pijul or Darcs? That said I couldn't find anything authoritative like case law or guidance from WIPO or other IP organisations, so any expert input would be appreciated in this thread. Darcs vs Pijul - Type 2 keywords and click on the 'Fight !' Also, merging (especially automatically) is limited by the quality of the data. level 1. For example, it's common for git to mix up function definitions by fixating on common lines (e.g. But that was rather the point: "I'm an egotistical bastard, and I name all my projects after myself. Darcs is the "smart" to git's "dumb" and Pijul is exploring if you can have "smart" without sacrificing "fast". FWIW, I liked the name "Anu" better. But don't be angry, i just wanted to play a little bit quality assurance...and read the documentation. Seems like the project was renamed to `anu`, and then back to pijul, and all documentation and hosting is a big mess right now. The Haskell DVC system that pijul "sort of" evolved from (theory of patches-wise mostly, just being careful given the stringent IP/credit language afoot), darcs, had this sort of semantic concept. One of the show-stopper complaints that I had about Pijul was the lack of a version identifier. At the very least, it reads rather strangely to me. (Unison does not use traditional text storage but stores code in a normalized repository). This is a big drawback and so we should hope to get some serious benefits to make up for it, but I don't think we do. ATM don't have time to read in depth but can someone explain if Pijul allows a user to checkout a subset of changes (say I only checkout one folder or a file)? Each line belongs to a patch and it can depend on the diffing algorithm which patch owns a particular line. It's certainly possibly I got some information wrong about Pijul. Git could learn from Pijul, IMHO, in the sense of better emphasis for newcomers for how to think in terms of patches. Would I want to put myself at legal risk, just because I want to try an experimental VCS? This is absolutely bogus. :-), Thanks for Pijul; I'm super-excited about the possibilities. It's a much more complicated model to implement, performance isn't as good, and your model is closely tied to your diffing algorithm. > The finished prototype I built created standard character-based unidiffs, and it sounds like could possibly be slotted directly into Pijul now. No. Doesn't Cargo depend on being able to 'git clone' software for it to be installable? The gpl doesnt protect ideas, it only protects code. I’m unsure how git and darcs do that, but I suspect it requires some heuristic or … Of course, the elephant in the room is git: when git came out, most darcs users (eventually) switched over to it. Has some issues like: move not showing from where it is being moved; ineficient implementation ; A [file] might be an untracked or tracked file. I’m honestly shocked that the author, who is apparently an academic, flouts academic norms like this. I've been asked to review results of mine in the past, taken form arxiv.org and resubmitted by senior academics. Pijul/Any is written in Rust. I'm not expecting it to be fast until a week or two. That's a patent, and I do think that there exists papers that describes patented algorithms. Future possibilities: This would make it possible for the user to create a shortcut status command equivalent to that command of darcs ( darcs status ). report. I just tried to go there again and the page is offline. Pijul is a version control system based on patches, that can mimic the behaviour and workflows of both Git and Darcs, but contrarily to those systems, Pijul is based on a mathematically sound theory of patches. Got a serious bug in Atlassian product? Not my cup of tea either. True or not, I will not further investigate what Pijul is. zseri today at 11:00 . best. I'm the author, and you just made my day. I just hope the command line tool gets a good 3-letter binary, "pijul record" is a bit awkward, maybe "pjl"? I think this sounds nice but it feels difficult to me. Darcs is a distributed version control system created by David Roundy.Key features include the ability to choose which changes to accept from other repositories, interaction with either other local (on-disk) repositories or remote repositories via SSH, HTTP, or email, and an unusually interactive interface.The developers also emphasize the use of advanced software tools for … Thanks again & wishing the best for Pijul. 100% Upvoted. Disclosure: as someone who was trained as a mathematician, I’m offended by attempts at restricting the free exchange of knowledge. IMO that could be a great selling point if this works even remotely like SVN partial checkout. Is the software easy to install? There is a "Sign in" form at the top right of the page, so maybe I should do that. Now "git," "pijul," and "anu." If you wish for an effective Version Control Systems product for your enterprise you need to take time to assess different solutions. While Pijul currently doesn't support binary files, plans call for it to do so soon. I also hope they allow you to use openssh as a fall back. The scripts in this repository fetch the repositories, apply any patches that are needed, use nix to reproduce the right build environment and build pijul+darcs and run the tests. Opened by zseri today at 11:00 . 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. It is exciting that people are interested in this work. To merge things, we have to find a common ancestor and reconstruct the changes made in … Versuchen Sie Pijul mit Docker Pijul ist die version controll des Sonderling.
