![]() ![]() With additions to the :require statement it would be clearer to include the namespace in the code example. (if (= pass pass1) (redirect “/”) (register handle))) (GET “/register” (register handle)) (POST “/register” (if (= pass pass1) (redirect “/”) (register id))))Īnd then on page 46 they refer to handle: (GET “/register” (register id)) (POST “/register” Should the code snippet not include home-routes? Otherwise the following exceptions is thrown:Įxception in thread “main” : Unable to resolve symbol: label in this context, compiling:(guestbook/routes/auth.clj:6:9)Īt (Compiler.java:6380)Īt (Compiler.java:6322) ![]() It appears the namespace for is missing a reference. :) And all those brackets need a tool to not be painful in the work.Historical errata for Web Development with Clojure And yes – about the code writingĬlojure is like a Lisp. So in my future talk will mention Visual Studio Code when it goes to code writing. Also I recommend to install one of “Join line” add-ons: it will be really handy to join line with for example Ctrl+J (and you will do line joins frequently). It has built in Clojure support (it’s not like P圜harm or real Visual Studio of course, but really better than Windows® Notepad or LT). Instead I recommend Visual Studio Code ( VSC). Also I’m installing all my soft to secured locations like Program Files and LT just could not start its own REPL from those location… Visual Studio Code ![]() REPL built in to editor? Ha! You may use dozens of another Clojure REPL implementations: Web apps, REPL started on your machine and used from your own browser, console apps, etc. Code investigation with this tool will be big pain. And it is just the natural way of that tool. Even some common “find” was introduced only after a few years (!) from the first public opening. But LT can be really annoying: it even can’t “just highlight” word occurrences in the file, for example. And there is Clojure plugin for LighTable. It has definitely beautiful yet simple design. And the skeleton of a simple but working project greatly simplifies matters. There is enough information in the Readme to start the research. You can see (and download) it here – at initial commit of one of my GitHub repositories. I came across a good task and I’ll share it. If you want of cource.įirst of all, you need a task. And because you may use same code on both server and client side, using great JVM with Java libs instead of the NodeJS on the background. Just because its concurrency design, its functional essence, its tools for the Web development, because it is easy to learn and to use ClojureScript even by the developer who is accustomed to the imperative programming. Is great for Web as a substitute for the JavaScript for the projects with complex logic. ![]() Is good for Java developers: less code, easier concurrency, etc.ĬlojureScript. For example, for those people who is beginner in some particular tool. Therefore, in some places I can give even basic information for beginners. Also you need to have development background in some other languages.Īctually, I do not know who will read my article. Of course you will not become an expert of any kind, but you can learn enough to make real applications like this: English Checkers Web App. To be precise, less than two days of the initial investigation before I started writing code. True story! 11 September 2016 on Development, Software, solution, tutorial, Clojure, ClojureScript, Web Menu Learn Clojure/ClojureScript in a few days. ![]()
