The problem is, if I use the switched lights, the ballasts won't let them come on until they cool down...10-15 minutes. I think IDE tooling for Unison could pretty easily give you the exact same experience. Edit: After thinking some more, it wouldn't conflict on a file-level, since the file itself has a different name. On the other hand this seems to be rather orthogonal to other (semantic) aspects of the language. Unison not only has that, it goes one step further to identify a function by its hash. Our options are either drop X, drop Y, or expend more effort/programming time to make a version which includes both X and Y. And yet somehow git calls the process of deciding what's in this new (version of the) file with two parents "resolving a merge conflict". Showing only topics with the tag "unison". Right from the heart. Nim, as a language, grew to be quite flexible within its prime syntax over the years - e.g. Content-addressable: no clue. 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. Learn more about HomeOwner. Definitely appreciate this honest and helpful, specific docs feedback, so thanks for taking the time to put it together. We do want the value of Unison to be straightforward given even a quick skim of the site, so: sorry about the current state, we'll try to improve it. I love languages or frameworks that have a step by step clear instructions on how to get started. Just having hashes this on the #include/import level of the source code would be a win for optimizing build and test of big code bases. So to get it to work with other languages, you would need a way to convert their abstract syntax into a DAG compatible structure. Today and every day. It does some amazing things that leave me shocked, like it can show you the assembly you generate while using a REPL. Any parts which are unchanged effectively have their hashes cached. I also like the "Ecosystem" part of Julia: Julia is a language I love that I don't see myself using sadly. No, take Reason as an example: it is basically Ocaml. 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. If I demerited the language for this, that's akin to complaining about a delicious roasted bell pepper because it doesn't taste anything like an onion. The word may also refer to: Computing * UNiSON , a music video game by Tecmo for the PlayStation 2 * Unison (computer conferencing), a Participate computer conferencing system operating out of Cincinnati, Ohio in … Wikipedia In other words, I think most of the benefits of this can live behind the scenes for other languages. I didn't realize it was something I'd have to explain. Seems like this could be implemented in other languages though, and don't really understand why we need yet another new language. Algebraic effect handlers no doubt seem to be the future of getting side-effects under control in programming languages, much like in the way of what immutability has done for data. If you'd like to learn more about the project, this Strange Loop talk is a good introduction. trees are immutable. 29. Which hash is the actual state of the app as it should be compiled and deployed right now? Explaining how the features helped to solve the problem at hand. Remove all the code not attached to the import tree anymore. The Nim language in 2008 (when it was known as Nimrod) had originally been planned a similar approach of considering a unified AST with multiple "syntax skins," and as far as I understand there used to be a limited implementation of this. Just to add to that - I’m kind of in the same boat here. Personally I think the right approach would be to use a structural type system similar to OCaml's. There's an FAQ item mentioning why type classes are not included[1] yet. https://en.wikipedia.org/wiki/Unison_(disambiguation), https://www.cis.upenn.edu/~bcpierce/unison/. [0] https://joearms.github.io/published/2015-03-12-The_web_of_na... > Once we have the SHA1 name of a file we can safely request this file from any server and don't need to bother with security. On the other hand, because those languages do not permit to build efficient abstractions they are also harder to read because each given sample, although unambiguous, perform very little. Unison: a new distributed programming language" by Paul Chiusano (2019) Lobsters: Unison language (2020) How Unison reduces ecosystem churn (2020) How Unison reduces ecosystem churn (2020) Unison: An Introduction and Q&A with Rúnar Bjarnason (2020) 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 … That said, I had to dig in the documentation to find code, and it didn't seem as obvious cause the syntax is definitely different from what I'm used to and there's weak syntax highlighting. Any references are secretly references to the table, so changing a definition is making a new hash and changing the reference, and renaming is changing the reference to name table. Whether it's code or some sort of video, every language should showcase something that tells you what development is like. Since it took me a while to find it, the relevant documentation is under "Abilities and Ability Handlers" [1]. The functor, and any code which depends on it, will remain unchanged. The benefit would be that a lot of existing code could be transferred into the initial 'blockchain', with all the current dependency hell being solved from day one. Despite having a C-like syntax, it is quite different from it. I'd say Rebol and Forth are less known exotic ideas for programming languages. But it's usually easier to paper over semantic gaps than unreadable syntax. Il permet donc de garder à niveau des répertoires se trouvant en même temps sur deux machines différentes. That's the thing that allows safe updates of shared dependencies. No changes are ever made to an existing file, so there are never any merge conflicts. It's kinda like Haskell, but every definition is turned into AST and put in a hash table. 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. Stoc epuizat. 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. That overhead you mentioned is why we decided that failure was a good result. You can't just pick one or the other, you have to combine the changes. The majority of its community is still focused on numerical scientific computing, but it's great for all sorts of usecases these days. I think this mental association must be done away with. 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. A friendly programming language from the future. Generate code from the AST, group it reasonably, and give you a view that is indistinguishable from a traditional source tree. For instance, can I not build my JavaScript code in similar ways: I would need a compiler that stores things in trees rather than dirs. A clean syntax makes the difference between always having to read each token vs. being able to speed-read by pattern matching high level structure when you don't need the details of that specific piece of code. A minor hit, the song would attract a good deal of attention in 1990, when three female singers each covered the song and placed it on their respective albums of that year. I don't think unison has interfaces or any similar construct yet. How could they. The only overlap with software are two unmaintained projects. They also allow recursive functions, but these should be simple enough to represent with a non-cyclic syntax tree. :). Is the project open source? But that description also applies to git. If you want to resolve merges using the workflow of git, you can generate scratch files and diff them, right?
