clojurescript

I want to write a Google Chrome extension, using ClojureScript. With ClojureScript I can use all the Google Closure libs, but afaik access to the Chrome browser is not included in those libs. So I want to wrap all the Chrome stuff in my own JavaScript lib. So far I tried creating my own jar that has a single JavaScript file that just creates a Foo object and exports the constructor. I'v added this jar to the lib directory of the ClojureScript compiler (which also has for example goog.jar), but so far without luck: Exception in thread "main" java.lang.IllegalArgumentException: No implementation

Is there a simple way to change document title and description (or other [:html [:head [:meta tags) from ClojureScript Reagent application? For example on every bidi route match change the title and description to match the new page content. Preferably this should work without using js/window so that the same code can be used in a browser as well as in server isomorphic pre-rendering (which I need for SEO). In the JavaScript/React world there are react-document-meta and react-side-effect which can probably be converted to Reagent components. But this way of handling side effects seems like a

Let's say I have a cljs file containing the following: (ns foo) (defn add [x y] (+ x y)) and wish to make this available as a JavaScript library to non-ClojureScript devs (primarily focused on node.js). I can do this: clj -m cljs.main -c foo But the problem is that the output is geared towards google closure's module system (e.g. goog.require ). I can set the target to none with the -t flag (as opposed to browser or node), and that... doesn't fix this. Setting it to node also doesn't fix the issue: no index.js (it's called main like in Java), no module.exports = blah blah . Seems like it's

I would like to define my own reader macro in clojure: (read-string "ßfoo") => (some_func :foo) Is it possible? It is possible to create tagged literals by having a reader map in data_readers.clj at the top of your classpath. This must be in data_readers.clj at the top of your classpath (usually src directory). {ß reader-demo.core/read-fn} This goes into reader-demo.core (defn some-func [arg] (str "some-func invoked with " arg)) (defn read-fn [arg] (-> arg keyword some-func)) Invoking #ß foo will return "some-func invoked with :foo" This technique is described here: The reader: Tagged literals

I am trying to convert a Javascript object to a Clojure. However, I get the following error : (js/console.log (js->clj e)) ;; has no effect (pprint (js->clj e)) ;; No protocol method IWriter.-write defined for type object: [object Geoposition] Yes, this object comes from the Geolocation API. I suppose that I have to extend IEncodeClojure and IWriter , but I have no clue how. For instance adding the following : (extend-protocol IEncodeClojure Coordinates (-js->clj [x options] (println "HERE " x options))) Yields an error when loading my code : Uncaught TypeError: Cannot read property 'prototype

I want to implement a function with ClojureScript to simplify js/console.log like this: (defn log [& args] (apply js/console.log args)) Calling it : (log "foo" "bar") throws: TypeError: Illegal invocation but this works : (js/console.log "foo" "bar") What is the problem ? Joaquin js/something is for accessing a js object, but you shouldnt nest dots after that, since it is not clojure compatible syntax and it was going to be removed. In older versions of the compiler (2138) your code works, but it is possible that it has been deprecated in newer versions of the compiler. Which version are you
