However, it needs to wean itself away from the all the Java tooling and not require a JDK. ClojureScript is within 10-20% of JavaScript or less (virtually the same). I can't find the quote for the of me, but it was from Rich Hickey and went something like: "First, you use Clojure to escape Java. This is a much more approachable syntax, reads much like a mix of Ruby and Python. When … Beauty is in the eye, and all that, but CL code still makes me want to claw my eyes out. The people who complain about parenthesis haven't used a Lisp long enough, that's all. I really hope this isn't true, Clojure is my favorite programming language. [36], Clojure's name, according to Hickey, is a pun on the programming concept "closure" incorporating the letters C, L, and J for C#, Lisp, and Java respectively—three languages which had a major influence on Clojure's design. February 6, 2019 • ∞. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. You can also of course mitigate the above with judicious use of let expressions but more often than not people inline anyway. Last active Jan 17, 2021. The most notable of these is ClojureScript,[69] which compiles to ECMAScript 3,[70] and ClojureCLR,[71] a full port on the .NET platform, interoperable with its ecosystem. Seriously you can write javascript in clojurescript. The good news is that Dart developers have less competition compared to developers who work with other languages. There are also things that clj has and cljs doesn't have and this is the top-class virtual machine. Developers who are new to clojure web development are recommended to try the excellent lein-ring plugin. IDEs, like SLIME, can easily traverse the code in many powerful ways. I have observed Elixir community and I have to say Jose and others did an excellent job fostering a healthy, friendly and warm community. I think it will continue on as a solid niche language for the foreseeable future, but it's highly unlikely that the language will grow by leaps and bounds barring some must-have innovation in the Clojure language and/or ecosystem that gets the tech world to take it more seriously. I love both Lisp & Python. If Clojure is to survive at all it will be among programming language dilettante dabblers. The JVM is super-powerful when it comes to compute tasks, but define a function on the REPL and Clojure will compile it, which is necessarily slower than what Python does. Well, vectors are a workaround for the challenges in creating homeoiconic lists that the JVM understands. The holy grail for javascript exists in Clojurescript. You say you don't really need to know the de-facto language of such "host" platforms, but that strikes me as putting a developer into a rather fussy and boxed-in posture if they're going to try and use the NewLang seriously/professionally. without any slowdown. I think Clojure is wonderful as a first language. Good for sharing scripts on my team. Nice E2 reference. Clojure is a modern, dynamic, and functional dialect of the Lisp programming language on the Java platform. Your favourite editor: You may find instructions for your favourite editor at one of these pages. The most popular is often, frankly, crap. Clojure is a tool for people who know their doing by people who know their doing. That was true a few years ago, but not anymore: In Haskell, data structures are immutable, persistent, and use structural sharing by default. It has excellent tooling. I don't mind Lisps and use Clojure regularly, yet I'd still argue your JS examples are easier to read than the Lisp ones. (corrolary: although a very similar language, Perl helps the computer think more like you do). Most people will never like it. Statistics, backend development, machine learning, whatever. I've said it before and I'll say it again, the industry can rip Clojure from my cold, dead hands. Leiningen war plugin. The JVM is solid, reliable and battle proven, is it not? Its the only time I do like a dynamic language (other than quick shell like scripts) and that is because the runtime is integrated so heavily with the development that essentially you are getting your types constantly checked (as well as auto completion and code lookup). Best guess is that in the end, syntax really does matter and lisp just doesn't have enough of it. Ruby works fine on Windows, until you hit a gem version that doesn't build. I love the language and the feeling I got solving little problems like Project Euler or 4clojure. This is great! Because there is no parenthesis problem; there's a newb problem. Clojurescript's benefits are so much more than the language. But this is rather a common pattern. Machine learning is a better way to produce AI. Hard to believe now, but back in the day there was serious debate about whether it should compete with the upstart Wikipedia. Sun (now deceased) was the company to work for, and James Gossling was the coolest cat in the Silicon Valley. Hell, as an Elixir guy, the first time I had to talk to the DB was jarring because it was "oh shit, it's a deep mutable data puddle again". Une fermeture est la paire formée d'une fonction et des références à son état environnant (l'environnement lexical). What I have thought the niche of Clojure and other languages like it are larger scale projects and established places that care about robustness and correctness. Java is actually … [17] Before Clojure, he developed dotLisp, a similar project based on the .NET platform,[28] and three earlier attempts to provide interoperability between Lisp and Java: a Java foreign language interface for Common Lisp (jfli),[29] A Foreign Object Interface for Lisp (FOIL),[30] and a Lisp-friendly interface to Java Servlets (Lisplets).[31]. If I write Perl, only I can understand it...and even that is temporary lol (I joke, but you get the point). But I am still a bit skittish of Clojure (JVM). There is already one language that is the queen of JVM, Java. I've had a very stable build for years now, whereas JS has had grunt, growl, webpack, etc. You aren't forces to use them but it is idiomatic Scala to be "pure"/non mutating. I'm baffled as to why Clojurescript + Leiningen isn't the preferred way. For javascript, that crowd of alternatives is so much larger, clojurescript needs to actually be good to stand out amongst all the others. I spent the better part of 2013 - 2015 learning and working with Clojure. [23][24][38][15], Clojure's approach to state is characterized by the concept of identities,[22] which are represented as a series of immutable states over time. Incanter is not the only game in town, FYI. The world is dominated by idiots and will always be. Nothing short of a miracle could save it at this point in time. Erlang's a different case because it optimises for responsiveness for small tasks. As such, Clojure makes immutability a default in the language, and mutation is hard to achieve without planning and extra effort. The language is the cherry on top. * built-in code-splitting (don't import the code for the settings page on the home page, automatically load it when the user goes there), also from Google Closure Compiler. For the JS developers out there, is this something that's of interest? The original proposal [1] for the Advice Taker was made in November 1958. Why are let bindings a vector? So my recommendation if you want to build programming language community - copy what Elixir did and it will be a good start. Until then I'll keep making my Javascript env look like Clojurescript. That all said, I think all 'piles-to-JS language bets are off in the face of WASM. See the somewhat controversial Allegro CL IF* macro for an example of this (I think that's what it was called; turns out that's really hard to search for). Check out Parinfer or Paredit - it makes Clojure and other Lisps a real joy to write IMO. And the front end developer tools and libraries in Clojurescript are _the best_ out there. I think the "killer app" that Clojure needs is that it should be compilable into C/C++ with the same great interop it has with Java. Clojure is especially suited to concurrency tasks. I had it in five minutes. Similarly Rails [2] looks like healthy, steady project. JS tries to be like Re-Frame, with Immutable.js, react-redux, etc. It's fun. As anything, you get used to it. This is because of prefix notation. IIRC, when Lisp was a leading language for "AI", it was specifically a leading language for expert systems, not ML. I just finished watching this talk "ClojureScript for Skeptics" (. This helps to simplify arithmetic expressions in some cases (e. g. polynominals) and allows to calculate a sum or product of any sequence, including empty one, using (reduce * xs). Push with Leiningen $ lein deploy clojars Push with Boot (using bootlaces) $ boot … Special-casing them to have "if the car of a list is cond, or this vector was preceded by let, ..., then every second element gets extra indentation if it's on a different line" vs just using the regular list formatting rules just squicks me. Which is, y'know, an awful annoyance for the people who use the language for other things—but boy does it pull people in. So is Matlab. Because of the strong emphasis on simplicity, typical Clojure programs consist of mostly functions and simple data structures (i.e., lists, vectors, maps, and sets): Like other Lisps, one of the iconic features of Clojure is interactive programming at the REPL. You don't really need to know Java to write Clojure, though you do need to know things about the JVM and about the particular (Java) types that the JVM's reflection and concurrency primitives are built on. Besides, at the technical level AI in the age of Lisp was a very different beast than AI today. Its a nice language, with not very nice tooling, that is hard to maintain and significantly different from the existing javascript code base you already have, with poor interop to the existing js ecosystem (it is poor, compared to some other compile to js languages). To some that probably "looks better" but it kills the ability to use emacs's transpose-sexps to swap the order of your let bindings around. Go was around and buzzy (closer to the peak, even) 5 years ago. Thus, project with 'I made X using Y' formula, while it might be a cool personal achievement, doesn't make it go beyond the confinement of its intrinsic functionality. I wonder, does #(* %1) do anything sensible? Stian Soiland-Reyes. Even to the extent that was due to language features being well-suited to the domain, there's still no real reason to expect that suitability to translate to the radically different approaches to AI today. Of course, you can apply "arguably" to every statement in the previous paragraph but the evidence appears to bear it out. GitHub Gist: instantly share code, notes, and snippets. deftype and defprotocol define dynamic behavior in Clojure. There are so many options these days that it's tough to stand out from the crowd. Due to the troubles of Lisp, abysmal sales and so on, Lisp Machines went out of business and was taken over by GigaMos Systems, who sold another troubled Lisp. [19] The current development process is community-driven,[20] overseen by Rich Hickey as its benevolent dictator for life (BDFL). [35] JIRA issues are processed by a team of screeners and finally Rich Hickey approves the changes. For the niche that Python enjoys (data science, devops, machine learning) there's also Hy ( which has more or less the same syntax as Clojure. I've never met enough Clojure developers that stuck with it long enough to move the meter to "massive uptick," so there isn't much of a down-slope relative to "alive." - not many setups give you all of this. So there's probably been even more added I don't know about yet. This through decades and generations of programmers. Interoperability with existing code in that ecosystem is also nice, but secondary; people using your language want to use your language, after all; if they wanted the best interoperability with Java, they'd just use Java. Clojure (/ˈkloʊʒər/, like closure)[15][16] is a modern, dynamic, and functional dialect of the Lisp programming language on the Java platform. No simple syntax, no really easy way to write macros. Just follow the trend and keep making it easy to do whatever just became popular. IDEs will also easily complete the parentheses for you, and will warn you of a missing parenthesis. So to take the ML pole position, Clojure would need to gain traction beyond all of these. It's unfortunate that people in this thread seem to down on the language, but the only possible way I would stop using it is if I literally cannot earn income with it. Seriously, get over your Emacs hate (if you have any) because Emacs is to Lisp family languages what IntelliJ is to Java. They're just scope delimiters. Case in point: I find Bucklescript to be absolutely amazing (generated binaries on par with size of hand written JS) but Scala.js is a better fit since I've been writing Scala for 6 years. Javascript is pretty slow as it is, and clojurescript is even slower. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. In the last couple of months I've been playing around with different solutions for actor based programming. Python helps people think more like the computer. It doesn't have literal syntax for hash tables, but it's a trivial read-macro if you can't live without it (although alists have some other nice properties like easy shadowing/popping of bindings, and the kind of associations you would want to write as literals are generally small enough that their O(n) lookup isn't a problem). No need to care for special operator precedence rules. I think that only works for concrete things, so in OO that would read: objects can die, classes can't. This sounds petty but I actually have some rationalization for it. Lisp or otherwise. I feel like Clojure is more of a language that just happens to exist in the same package ecosystem as Java, and which offers a good syntax for fluently. Datomic should be open-source. [55][15] Clojure's reader supports literal syntax for maps, sets and vectors in addition to lists, and these are compiled to the mentioned structures directly. It allows a lot of easy structure editing with a decent editor. Since states are immutable values, any number of workers can operate on them in parallel, and concurrency becomes a question of managing changes from one state to another. It's true of everything in life. A web server written in clojure, doesn't make it a space rocket, and certainly not making you a rocket scientist. All in all the syntax just didn't seem well thought out to me. As a functional language, emphasis is placed on recursion and higher-order functions instead of side-effect-based looping. Plus it's sort of a toolkit to be used in many different ways. An extension that supports REPL like Lumo and step through debugging within visual studio code. But the holy grail for me would absolutely need static typing. Also Common Lisp is better in every way ;) There's even a JVM implementation (ABCL) for people who like that sort of stuff. En d'autres termes, une fermeture donne accès à la portée d'une fonction externe à partir d'une fonction interne (on dit aussi que la fonction « capture son environnement »). And even if they go fully LGPL now, the perception of closedness tends to stick around. If immutable data structures and a functional approach produce easier to test, less buggy code it can be argued those language features contribute to making the world a safer place. Concurrency made easy with Clojure and Pulsar September 22, 2015 Clojure. Things are looking very bad for Clojure As many of us are already aware, Clojure continues to lose market share. You're conflating two different things that people like about Lisps here. Minus the arity error, 1-argument * is an identity. It usually works all right if you can stay a few Ruby versions behind and carefully pick the gems you use, but it'll likely fall apart if you try to collaborate with anyone using Mac or Linux, updating to the latest Ruby and gems and grabbing any gem they feel like. The few times I have, they make sense. When you first started to learn C style syntax, it was likely just as confusing. before I had to have a vim plugin in every ide. Python is definitely easier to learn as a second language if you're already a trained programmer coming from the C family. There seems to be a very nice solution to the parenthesis problem: > I have no idea why it hasn't caught on. Clojurecademy Web Application. Of course as the article says, "simple" and "easy" is hardly a dichotomy; what I described are extreme cases, and most if not all languages fall somewhere in between and exhibit properties from both sides. How much experience do you have with ClojureScript and other compiled to JS languages? "I'm an artist, and if you give me a tuba, I'll bring you something out of it” - John Lennon. Among other things this means that type annotations are not required for code to run. Also, the more Clojure users out there, the more people are potentially able to "jump" to the other Lisps like Racket, Arc, Scheme, and CL. I had never touched Clojure until a few weeks ago. Is it dead? Python FFI is almost free to call into C so end-to-end performance is better than Clojure. If you wanted to kill it, you'd have to wrestle it from my cold, dead hands first. Clojure's hash map, just like hash tables and dictionaries in many other languages, has a mechanism to iterate through the entire collection. PyTorch, on the other hand, is gaining popularity. What's the syntax for if and else? S-Expressions were originally an intermediate form for a more algol-like syntax[0], but became the primary form of representing Lisp because allowing the programmer to manipulate the AST is extremely useful, arguably what makes Lisp Lisp. That indeed was a complete turn-off. Once you got used to this, this was really pleasant to write and mutate code. Is it dying? The people who use it seem to just like it as a language; and I get that, that's a thing. [33] Anyone can submit issues and ideas at,[34] but to contribute patches, one must sign the Clojure Contributor agreement. Also, WASM is just around the corner, which will probably make this a non issue. Despite recent software hitches, Mac OS has been far and away a superior experience for development than when I was trying to run RailsInstaller on my Windows machine. I don't know but it seems to me Ruby is dying the same way anything else with 200,000+ questions on Stack Overflow is dying (i.e. Is java dead in 2020? It's incredibly common for Lisps. Especially if ClojureScript could become more attractive than (or at least have a real solid standing amongst) Elm/PureScript/etc., I could see that being a big boon to Clojure development as well. One of the best things about ClojureScript is the build process using lein. Ditto, thanks to my first job, and I don't regret it, either. For example, the following code gets evaluated immediately because it just defines a number, no sequence is involved: (def n (pinc 0)); => immediately prints "." [25], Commercial support for Clojure is provided by Cognitect. compiles programs into bytecode, which is then interpreted and run by the JVM. Agreed. The hand writing is on the wall: Clojure faces a bleak future. Ruby works great on that for me, every version, every gem. These are very basic questions, but enou… As far as I'm aware, there's no Clojure implementation. The only other JVM dynamic language in your list is Apache Groovy. Worry about setting a deep value that is regular JS. which is still private lean mean business and personal and civil enlightenment oriented? Going further, it seems like the whole category of alternative languages hit a peak about three years ago, and interest has been dwindling since. It's not emotional, no. If you need to do some hardcore concurrency related stuff, Clojure might be especially suited to that task. Transpiler technical benefits. Getting Clojure: Build Your Functional Skills One Idea at a Time (English Edition) 22,78€ 4: while No Success Try Again If Dead Break - Coding Notebook Journal | 120 pages (6"x9"): Gift for Programming Lovers: 6,62€ 5: Structure and Interpretation of Computer Programs, second edition (MIT Electrical Engineering and Computer Science) 54,00€ 6 Making Clojure open source but Datomic closed is, for me, still the equivalent of building a beautiful world you can wander around and explore for free forever, but whose roads and and signs all lead up to a single temple at the center, which in turn has a big sign on it saying: 'magic happens here; don't look under the covers; don't mess with it; and also... please pay.'. Anything above that is not the JVM, it's something else. I have for years thought I'd need a license to develop commercial Qt applications and not evaluated it seriously for that reason, even though by that time it was already LGPL. Common programming mistakes for Clojure developers to avoid (6) What are some common mistakes made by Clojure developers, and how can we avoid them? Each thread then repeatedly selects two random positions in two random vectors and swaps them. But I think you are crazy. Whether it's scheme or clojure or arc, every once in a while a new lisp comes along, and they never make it. Pulsar.
