A reasonable example of a good page that is informative and provides lots of examples (enough at least!) Download Unison - Music Production Studio for free. Is it possible to depend only on an interface, and not on an implementation? However, I'm not the target developer for Julia. So there is no merge conflict in the git sense. 13.9k members in the functionalprogramming community. In practice I think this means very easy refactoring unlike today’s programming languages where it’s hard to find every use of an identifier. > All changes result in a new object/file ... therefore never any merge conflicts. Doesn't that defeat separate compilation? You can use git without branch names if you want, living in a world of pure immutable hashes. TBH if you're creating a new language after 2014 you should be thinking about how to get good syntax highlighting and other tooling from the language definition itself, because you're competing with a ton of mature languages that had to do this manually through a ton of effort of their communities. I remember having read somewhere that the initial versions of lisp where missing an actual syntax, and that it was planned to add one later, but that until then users would have to write directly the AST in an ugly syntax full of parentheses and devoid of familiar syntactic landmarks. It might be non-trivial to structure things nicely, but I think theres a good chance your generated structure would be better organized than a traditional codebase. I'd also look at Unison, for a more recent exotic programming language concept. With git, you can do a text merge. Explaining how the features helped to solve the problem at hand. Or does the user provide the hash for the main function they wish to run? 29. The most hopeful case is that there is ONE place that isn't 'strictly append only', and that's, for lack of a better term, the 'main pointer'. It only stores new objects/files, named based on a content hash. That is a fundamental property of this interaction; no language bells and whistles can ever change this fact. It was revelatory. Their book on FP is legendary in some circles. For instance, C and Go are easy because they do not hide anything and what one sees is pretty much unaffected by what one does not see. I assume they thought about this and have some sort of tooling for “traversing” conflicts from the root, choosing my function, your function, or allowing a merged function to be created. I don't. On second thought, I have two major categories of concerns: > 1) If I fix a bug in a function, (thus creating a new version of an existing function) how do I propagate that fix to all that code that transitively depends on the buggy version? Anyone have a transcript to link? Reminds me of. I’m not sure how this can benefit in practical ways, but the concept itself is pretty interesting to see. distributed computations. But it's usually easier to paper over semantic gaps than unreadable syntax. No worries. https://reference.wolfram.com/language/ref/TraditionalForm.h... https://reference.wolfram.com/language/ref/TeXForm.html. It's mainly just an issue of manpower on our end (we do accept doc contributions, but probably we should be doing it); having fresh reader eyes on it like this is still valuable though. The "codebase" that is managed by ucm sounds very similar to Smalltalk images. Most build systems today just operate on file time stamps which has a lot of tricky cases where the build system gets out of sync and requires a make clean to get back into decent shape. It's a modern, statically-typed purely functional language, similar to Haskell, but with the ability to describe entire distributed systems with a single program. Pay off debt Renovate your home. The only overlap with software are two unmaintained projects. On the other hand, they allow to build abstractions that make programs more terse and therefore easier to read. I find the content-addressed, name-independent, immutable (kind of blockchainy) approach to source code very interesting. I think this lets someone know immediately if it's interesting to them or not. Its music incorporates a range of contemporary genres with a mix of ballads and dance songs. Small code samples tell me next to nothing. It is getting a bit philosophical: you can view it as a conflict. I would like to receive 10% off my first purchase, easy access to free products, special offers, and more by signing up to the Unison newsletter. I know what that is. Julia is a very flexible language. That'd be a bit problematic. No code examples, nothing linking the currently known to this new paradigm-shifting stuff. The big issue is the presence of cyclic dependencies between parts of code. If you have some fundamental type which an entire codebase depends on, then modifying it will essentially require recomputing hashes for the most of the codebase. The syntax barrier is usually much smaller than the language itself. For many programming languages the line count of "hello, world!" I did not fully read the introduction yet, but in my mind, in a truly content-addressed system this is not a conflict: 11.00 lei. I did not think this through deeply though... Maybe some aspects of existing languages prevent them to be handled the 'unison way'? Edit: After thinking some more, it wouldn't conflict on a file-level, since the file itself has a different name. What makes a program easy to read is not its syntax but its semantic, that dictates how much context one has to keep in mind to be able to understand a small fraction of code. See development.markdown for a list of build commands you'll likely use during development. Whether it's code or some sort of video, every language should showcase something that tells you what development is like. K. Let's try the docs. Git has this problem only as far as the developer's storage of the history of all files is concerned. http://unison.repo/b89eaac7e61417341b710b727768294d0e6a277b could represent a specific function. [1] https://www.unisonweb.org/docs/language-reference#abilities-... One problem I did find: Somewhat deeper into the tour, the tour makes the claim: > a Unison codebase can be versioned and synchronized with Git or any similar tool and will never generate a conflict in those tools. I've probably been thinking about the concept for so long that it doesn't occur to you that the phrase wasn't that well known. It doesn't matter that much when I have found a piece of code that I need to read and understand every detail of, but that is a tiny proportion of the amount of code reading I do - most of the time reading code is about grasping overall structure to learn a codebase well enough to find the points you need to focus on and read. Your Help Needed If you know Unison, please write code for some of the tasks not implemented in Unison. We could try dropping them again, and people would adjust after a few hours, but that doesn't mean that the spaces and punctuation don't provide value. Unity targets WASM. this Strange Loop talk is a good introduction. The fundamental idea of uniquely addressing functions based on a hash of their AST is mind-blowing to me. Here's a list of the latter. Otherwise you will just keep collecting junk forever Honestly git has the problem too, but I expect orphaned/dead code will happen a lot more with this approach. Is it a hash of an implementation, or a hash of an interface? Kind of what was previously conflict resolution becomes part of regular programming... A slight perspective change. It began as an experiment: rethink all aspects of the programming experience, including the core language, runtime, tooling, as well as code versioning and publishing, and then do whatever is necessary to eliminate needless complexity and make building software once … > The Welcome is the state of the project without saying anything about the language itself. Syntax is something you become used to in a few hours. You can then define concrete representations of types independently of the functor, and instantiate them against the functor afterwards. That's not exactly how it works: Bucklescript is a JS backend for OCaml, and ReasonML is an alternative syntax for OCaml. Since Unison works best with pure functions, most system interfaces would presumably be emulated. Unison is an open source functional programming language with special support for building distributed, elastic systems. I'd say Rebol and Forth are less known exotic ideas for programming languages.
