it can not track things like "This calls a function introduced in patch X" which makes the cherry-picking functionality of very little value. > All the above has been complicated by the fact that I accepted an academic job in August 2018, only to be told, after I had resigned from my previous job at Inria and moved to another country, that I wouldn’t be allowed to work on my own research projects (including Pijul), or at least that the legal status of that work outside of my holidays was unclear. hide. 3 years ago. Very cool. That is, ”pee-jewel” but with short vocals instead of long ones for both words. Compare Darcs vs Simul Docs. They only say that it is difficult because of all the interoperability issues they keep discovering. Of course it does. Also, merging (especially automatically) is limited by the quality of the data. I really have invested time into this to try to get a proper understanding. 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. I have some private code on Darcshub though. I also hope they allow you to use openssh as a fall back. Oh and provide an official way to pronounce it! spreading data and parentheses across multiple lines to work better with line-based tools like git, or keeping revisions in the files themselves, etc. Let's say I have a local git branch with 10 commits on top of master. Sure, it's awesome if those tools can host themselves, but what about being able to set it up quickly? Pijul itself is in an alpha stage, but is based on a number of other things we’ve needed to write, among which a key-value store known as Sanakirja. A quick search seems to indicate that algorithms cannot be copyrighted, only an "expressed representation of a work" can be copyrighted. More awareness of tools like darcs and pijul does help in that by presenting UXes built around it, it does drive people to ask how to do equivalents in git. I'm surprised I've never encountered it before. I clicked on the "nest" link (hoping for a download source tarball button), but this link 404s: https://nest.pijul.com/pijul_org/pijul, Possibly this is the right home for pijul: https://nest.pijul.com/pijul/pijul, I cannot find an issue tracker. Honestly, the whole faffing around with the name leaves me with a very bad taste in my mouth. I get a link error involving libclang. However I do often find myself annoyed by the lack of a "change" concept other than the immutable commit. I find it sad to see that Atlassian does not advertise their own support for Mercurial. Each line belongs to a patch and it can depend on the diffing algorithm which patch owns a particular line.

They make the claim that cherry picking "just works" but I think this misses the big picture. I also came here to comment on this. viewing diffs, bisecting to pin down a bug, etc.). I do work in the area of data storage myself. 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. Is it novel or standard in some places? ), Haskell is not my usual habitat. 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. 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. to be the case here. The project seems very interesting, > cargo install pijul --version 1.0.0-alpha, (needs some native dependencies like zstd). A very gentle way of phrasing this ;-) Thank you. This also applies if that rediscovery happens in the future, including in zero, one or more years. really, really excited for this. darcsden 1.2 beta built Jun 23 201810:48:19; report problems to simonsimon EDIT : Oh crap : When you submit a paper to a journal, you don't get to pick your reviewers. Where's the registration button? First 'Linux', now 'Git'". For overall product quality, Darcs earned 6.2 points, while Simul Docs gained 8.0 points. I'd be very interested to experiment further with it now that one of the patch algebra VCSes has finally adopted a "chunk" option. However according to this post that has now been resolved which is fantastic news. The winner is the one which gets best visibility on Google. Any diff you see is just for display purposes or for input to the three-way merge algorithm. If not, you totally should! Considering how much time one spends swearing while trying to resolve issues with version control, I think. Consider some changes from A to B: A semantic-aware diff could do better. The registry is controlled using git, and Cargo allows you to pull in software via git, but Rust projects don't need to be using git. It went on to be a best seller. Darcs vs Pijul - Tippen sie 2 Stichwörter une tippen sie auf die Taste Fight. At the very least, it reads rather strangely to me. But that was rather the point: "I'm an egotistical bastard, and I name all my projects after myself. Compare Simul vs Darcs. [1]: https://en.wikipedia.org/wiki/Interval_(mathematics). That page has always been dog slow. Thrussh -- they remake ssh, but they never say why. Has any1 had success compiling it on mac? 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). https://en.wikipedia.org/wiki/Islamic_Jihad_Movement_in_Pale... https://git.wiki.kernel.org/index.php/GitFaq#Why_the_.27Git.... https://stackoverflow.com/a/11426261/884682, https://twitter.com/nuempe/status/1325756834947461120. I'm the author, and I'm entirely guilty of that misunderstanding. Apart from speed, we are also interested in a better way of handling conflicts between patches, which is also something that Pijul … Please correct me if I have! I think this would be very hard if not impossible to get from the graph-of-byte-ranges representation. I've heard of cases where people just ripped off parts of another's work as PHD. 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. Still a tiny fraction compared to available tokenizers in Pygments: Encoding a generic, potentially versioned AST in S-expressions seems feasible. But that seems to go against everything I thought I knew about "clean room reverse engineering"? There’s no way I’m ever going to be typing pujil, no wait pijul, any amount of times during my daily work. I was just explaining my cautious wording. Yeah, they are basically claiming patents on the ideas presented. 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. But don't be angry, i just wanted to play a little bit quality assurance...and read the documentation. Indeed, in Git (using diff3 to merge), when Alice adds lines at the beginning of a file and Bob adds lines at the end, some of Bob's line can get merged into Alice's new lines. Doesn't Cargo depend on being able to 'git clone' software for it to be installable? [darcs-users] Pijul 0.1 Florent Becker florent.becker at ens-lyon.org Thu Oct 1 17:27:16 UTC 2015. 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. 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. pijul; pijul; 135 . tux0r - have you written any posts on Pijul or Darcs? 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. IMO that could be a great selling point if this works even remotely like SVN partial checkout. Ssh deals with keys and accounts and all that which SSL/TLS don't do. 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. Big problem on Git in game dev, is the fact that you often don't want to download everything. 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. 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. To me it seems little more than a hobby project of someone with an interest in version control systems. For example Pijul aims to focus on first creating a patch, whereas git tutorials IME tend to focus on first creating a branch, then editing files, and only later discussing patch oriented areas such as `git add --patch` and `git stash`. Sort by. I'm not sure what you mean. :-/ EDIT: and thanks for all your hard work on Pijul! There are many git users, most of whom … 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. The gpl doesnt protect ideas, it only protects code. This is intended as the docs for the new Pijul still have to be written and keeping up the old ones would have likely lead to confusion. One great use-case for git patches is moving files between repos without losing their history. The original comment follows. Pijul's whole setup seems like it would solve a bunch of problems I have with git. 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 ! Sure, but then you can't use your existing ssh credentials. See tompazourek's message for quote or visit: I'm the author. Pijul/Any is written in Rust. It was just a reaction to a number of plagiarism events that have happened to me in recent years. The idea of Pijul came while Florent Becker and myself were writing a paper on self-assembly. Git has no notion of files, but this is how Darcs does it. Also all documentation is 404. The funny thing about names is whatever they are, you end up getting used to them. And distribute that by default as well, otherwise everyone defines their own mutually incompatible aliases. At the practical level, … Featuring nest.pijul.com. (Or the vast number of TextMate grammars in the wild, such as editors like VS Code have standardized on.). Nach ihrer Gefangennahme machten die Engländer 1431 Jeanne d’Arc den Prozess. The biggest problem IMO is that Pijul is more similar to git rebase than git merge. return 1 + 1 + 2; and a patch C based upon B changes that to: > The finished prototype I built created standard character-based unidiffs, and it sounds like could possibly be slotted directly into Pijul now. button. Negative Marketing. At some point we started thinking about the shortcomings of Darcs (Florent was one of the core contributors of Darcs at the time). The required libraries are openssl libsodium llvm(which contains libclang) xxHash zlib zstd libgit2 pkgconfig, edit: with nix on macos, this 'should' be enough, I've been meaning to try out nix for a while anyway, so this was a nice nudge. Code ; Changes ; Discussions ; CI #308 Add a rollback subcommand. In this sense pijul is like darcs, but it doesn't suffer from exponential-time edge cases when merging; hence it should be a pareto improvement. I do know what I'm talking about, I wrote the damn thing. (Unlike many HN commentators, who are too trapped inside the git way of thinking to realize its limitations ;-). Pijul's cherry picking only "just works" with respect to merging lines of code. If not, you totally should! In other words, Pijul works in polynomial time for all patches that systems other than darcs know of. You will need nix to run them. Zunächst mit Docker Das ist langsam für schnell Sie brauchen ein Dockerfile. Why develop my own extension instead of contributing to the existing one? I made an account in their "nest" a while ago, but it's all too alpha-quality just yet. Fortunately, pijul commands have pretty close analogues inother VCSes. Etc. :-), Thanks for Pijul; I'm super-excited about the possibilities. Now if I update my master and do "git rebase master" I must make sure that each one of those 10 commits resolves cleanly on top of the new master. I still drop into the git CLI if I need to do things like editing the contents of lines, e.g. Very interesting! At the same time, … But I’d be excited if someone figured out how to do it. save. Even though Git is already pretty great in my opinion, there's always stuff that can be done better. 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.. It can automatically pull in patches that the lines of code you are merging depend on for the merging algorithm, but it can not track things like "This calls a function introduced in patch X" which makes the cherry-picking functionality of very little value. GPL on the other hand doesn’t have an expiry date. In fact, making an s-expression plugin which is robust across various Lisp dialects might be a good way to bootstrap the user community. At the end of the article it says that the rename (to Anu) has been reverted. New comments cannot be posted and votes cannot be cast. And then you have to use subtree and submodules... And that's a nightmare. > 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. In contrast with git, this merge operation is well-defined and has all expected … 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. I think a particular part of the problem is to get the diff algorithm to match parentheses correctly. What they're looking for is a patent, not copyright. But I don't think that's how licenses like the GPL work? Hoping the author reads this. Without reference to the source language, the most native rendering of this based on spelling definitely has short vowel sounds. Its distinctive feature is to be based on a sound theory of patches, which makes it easy to learn and use, and really distributed. Anyway, what I find weird about the Pijul project is that they place the barrier to entry so damn high, that it's absolutely not motivating to even give it a try: - The Pijul front page (https://pijul.org) has a prominent link in the middle that points to their source code hosting service, Nest. I think, it's less this, and more preventing others as passing these ideas as their own. You should read the other comments made after yours... apparently that was just a misunderstanding and not what the author intended. I just tried to go there again and the page is offline. This page is powered by a knowledgeable community that helps you make an informed decision. 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)? However, even patents can’t be licensed in perpetuity, so they can’t possibly apply to all future work. > On a quick glance, that seems (?) Of course, the elephant in the room is git: when git came out, most darcs users (eventually) switched over to it. darcs get url . Would that require 1 or 2 conflict resolutions? I haven't looked at darcs in many years, but it would be unsurprising if it had evolved to similar generality like … I'm the author, I understand how that comment of mine could be misinterpreted, which is why I removed it. Opened by zseri today at 11:00 . As a statement of fact the claim is simply false.

pijul vs darcs

I guess that the author might be an astronomy aficionado ? I think your biggest challenge now is going to be everything besides the software itself that makes a project successful: Is the website fast and inviting? Days have 24 hours, projects only move one step at a time. The one concern I'd have for a custom implementation is when they roll their own crypto... On a quick glance, that seems (?) Nah, Atlassian does only what makes sales go high. The snapshot model is fundamentally different and doesn't require resolving conflicts in the same way. Is this project still going or is Anu the future? Am I misunderstanding ? (It's so very common to work on things side-by-side and then want to split things out into more logical commits to describe things as individual changes.). There's still plenty of room to explore possible new VCS possibilities, just as we continue to explore things like programming language possibilities. I'm not angry at all! > - As BlackFingolfin pointed out, the blog post has a "Warning about licenses" at the top. 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. (Unison does not use traditional text storage but stores code in a normalized repository). Actually, both notations are described by an international standard, according to Wikipedia [1]. I'm sorry to hear that, but making false and intimidating claims about copyright doesn't help your situation. Would I want to put myself at legal risk, just because I want to try an experimental VCS? 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. 2. pijul add tells pijul that it should start tracking a file, much like gitadd or hg add. Until there are packages in linux distributions, you can get it with `cargo install pijul --version 1.0.0-alpha`. Every user can use whatever diffing algorithm they want when generating patches for use in three way merge and then only the results are stored. Git, Mercurial, and Fossil are probably your best bets out of the 14 options considered. 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. Which part of my reply do you object to? > it can not track things like "This calls a function introduced in patch X" which makes the cherry-picking functionality of very little value. > All the above has been complicated by the fact that I accepted an academic job in August 2018, only to be told, after I had resigned from my previous job at Inria and moved to another country, that I wouldn’t be allowed to work on my own research projects (including Pijul), or at least that the legal status of that work outside of my holidays was unclear. hide. 3 years ago. Very cool. That is, ”pee-jewel” but with short vocals instead of long ones for both words. Compare Darcs vs Simul Docs.

The registry is controlled using git, and Cargo allows you to pull in software via git, but Rust projects don't need to be using git. It went on to be a best seller. Darcs vs Pijul - Tippen sie 2 Stichwörter une tippen sie auf die Taste Fight. At the very least, it reads rather strangely to me. But that was rather the point: "I'm an egotistical bastard, and I name all my projects after myself. Compare Simul vs Darcs. [1]: https://en.wikipedia.org/wiki/Interval_(mathematics). That page has always been dog slow. Thrussh -- they remake ssh, but they never say why. Has any1 had success compiling it on mac? 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). https://en.wikipedia.org/wiki/Islamic_Jihad_Movement_in_Pale... https://git.wiki.kernel.org/index.php/GitFaq#Why_the_.27Git.... https://stackoverflow.com/a/11426261/884682, https://twitter.com/nuempe/status/1325756834947461120. I'm the author, and I'm entirely guilty of that misunderstanding. Apart from speed, we are also interested in a better way of handling conflicts between patches, which is also something that Pijul … Please correct me if I have! I think this would be very hard if not impossible to get from the graph-of-byte-ranges representation. I've heard of cases where people just ripped off parts of another's work as PHD. 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. Still a tiny fraction compared to available tokenizers in Pygments: Encoding a generic, potentially versioned AST in S-expressions seems feasible. But that seems to go against everything I thought I knew about "clean room reverse engineering"? There’s no way I’m ever going to be typing pujil, no wait pijul, any amount of times during my daily work. I was just explaining my cautious wording. Yeah, they are basically claiming patents on the ideas presented. 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. But don't be angry, i just wanted to play a little bit quality assurance...and read the documentation. Indeed, in Git (using diff3 to merge), when Alice adds lines at the beginning of a file and Bob adds lines at the end, some of Bob's line can get merged into Alice's new lines. Doesn't Cargo depend on being able to 'git clone' software for it to be installable? [darcs-users] Pijul 0.1 Florent Becker florent.becker at ens-lyon.org Thu Oct 1 17:27:16 UTC 2015. 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. 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. pijul; pijul; 135 . tux0r - have you written any posts on Pijul or Darcs? 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. IMO that could be a great selling point if this works even remotely like SVN partial checkout. Ssh deals with keys and accounts and all that which SSL/TLS don't do. 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. Big problem on Git in game dev, is the fact that you often don't want to download everything. 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. 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. To me it seems little more than a hobby project of someone with an interest in version control systems. For example Pijul aims to focus on first creating a patch, whereas git tutorials IME tend to focus on first creating a branch, then editing files, and only later discussing patch oriented areas such as `git add --patch` and `git stash`. Sort by. I'm not sure what you mean. :-/ EDIT: and thanks for all your hard work on Pijul! There are many git users, most of whom … 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. The gpl doesnt protect ideas, it only protects code. This is intended as the docs for the new Pijul still have to be written and keeping up the old ones would have likely lead to confusion. One great use-case for git patches is moving files between repos without losing their history. The original comment follows. Pijul's whole setup seems like it would solve a bunch of problems I have with git. 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 ! Sure, but then you can't use your existing ssh credentials. See tompazourek's message for quote or visit: I'm the author. Pijul/Any is written in Rust. It was just a reaction to a number of plagiarism events that have happened to me in recent years. The idea of Pijul came while Florent Becker and myself were writing a paper on self-assembly. Git has no notion of files, but this is how Darcs does it. Also all documentation is 404. The funny thing about names is whatever they are, you end up getting used to them. And distribute that by default as well, otherwise everyone defines their own mutually incompatible aliases. At the practical level, … Featuring nest.pijul.com. (Or the vast number of TextMate grammars in the wild, such as editors like VS Code have standardized on.). Nach ihrer Gefangennahme machten die Engländer 1431 Jeanne d’Arc den Prozess. The biggest problem IMO is that Pijul is more similar to git rebase than git merge. return 1 + 1 + 2; and a patch C based upon B changes that to: > The finished prototype I built created standard character-based unidiffs, and it sounds like could possibly be slotted directly into Pijul now. button. Negative Marketing. At some point we started thinking about the shortcomings of Darcs (Florent was one of the core contributors of Darcs at the time). The required libraries are openssl libsodium llvm(which contains libclang) xxHash zlib zstd libgit2 pkgconfig, edit: with nix on macos, this 'should' be enough, I've been meaning to try out nix for a while anyway, so this was a nice nudge. Code ; Changes ; Discussions ; CI #308 Add a rollback subcommand. In this sense pijul is like darcs, but it doesn't suffer from exponential-time edge cases when merging; hence it should be a pareto improvement. I do know what I'm talking about, I wrote the damn thing. (Unlike many HN commentators, who are too trapped inside the git way of thinking to realize its limitations ;-). Pijul's cherry picking only "just works" with respect to merging lines of code. If not, you totally should! In other words, Pijul works in polynomial time for all patches that systems other than darcs know of. You will need nix to run them. Zunächst mit Docker Das ist langsam für schnell Sie brauchen ein Dockerfile. Why develop my own extension instead of contributing to the existing one? I made an account in their "nest" a while ago, but it's all too alpha-quality just yet. Fortunately, pijul commands have pretty close analogues inother VCSes. Etc. :-), Thanks for Pijul; I'm super-excited about the possibilities. Now if I update my master and do "git rebase master" I must make sure that each one of those 10 commits resolves cleanly on top of the new master. I still drop into the git CLI if I need to do things like editing the contents of lines, e.g. Very interesting! At the same time, … But I’d be excited if someone figured out how to do it. save. Even though Git is already pretty great in my opinion, there's always stuff that can be done better. 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.. It can automatically pull in patches that the lines of code you are merging depend on for the merging algorithm, but it can not track things like "This calls a function introduced in patch X" which makes the cherry-picking functionality of very little value. GPL on the other hand doesn’t have an expiry date. In fact, making an s-expression plugin which is robust across various Lisp dialects might be a good way to bootstrap the user community. At the end of the article it says that the rename (to Anu) has been reverted. New comments cannot be posted and votes cannot be cast. And then you have to use subtree and submodules... And that's a nightmare. > 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. In contrast with git, this merge operation is well-defined and has all expected … 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. I think a particular part of the problem is to get the diff algorithm to match parentheses correctly. What they're looking for is a patent, not copyright. But I don't think that's how licenses like the GPL work? Hoping the author reads this. Without reference to the source language, the most native rendering of this based on spelling definitely has short vowel sounds. Its distinctive feature is to be based on a sound theory of patches, which makes it easy to learn and use, and really distributed. Anyway, what I find weird about the Pijul project is that they place the barrier to entry so damn high, that it's absolutely not motivating to even give it a try: - The Pijul front page (https://pijul.org) has a prominent link in the middle that points to their source code hosting service, Nest. I think, it's less this, and more preventing others as passing these ideas as their own. You should read the other comments made after yours... apparently that was just a misunderstanding and not what the author intended. I just tried to go there again and the page is offline. This page is powered by a knowledgeable community that helps you make an informed decision. 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)? However, even patents can’t be licensed in perpetuity, so they can’t possibly apply to all future work. > On a quick glance, that seems (?) Of course, the elephant in the room is git: when git came out, most darcs users (eventually) switched over to it. darcs get url . Would that require 1 or 2 conflict resolutions? I haven't looked at darcs in many years, but it would be unsurprising if it had evolved to similar generality like … I'm the author, I understand how that comment of mine could be misinterpreted, which is why I removed it. Opened by zseri today at 11:00 . As a statement of fact the claim is simply false.
