Re: [ANN, GSoC] A Common Clojure Source Metadata Model

At the moment, the extension system is very tied to Cursive and to IntelliJ internals. Several people have asked whether I could extract the functionality so it would be reusable, but since I haven't even had time to get my own API public yet this is unlikely to happen - it's a very significant pie

Re: Interop: mutability vs. inheritance

Thanks--you're right, of course, Marshall. (I almost added "without writing it in Java" somewhere in the first part of the post. That doesn't mean writing parts in Java isn't worth considering. I'm just trying to figure out what will and won't work in Clojure itself.) -Marshall On Wednesday

Interop: mutability vs. inheritance

Is the following correct? The only way to define *multiple* mutable instance variables/fields for a class visible in Java is by using deftype with :volatile-mutable or :unsynchronized-mutable. The only way to inherit from a concrete Java class is by using gen-class or proxy. gen-class allows a

Re: Using :refer 'sparingly'

I've been using :refer [...] exclusively but I've been growing increasingly disenchanted with it; it's just a nuisance when you're interrupted by having to address the ns to add a command you didn't previously know you needed. On the other hand, not using :as can become just as much of a nuisan

Re: How to use a java web service project in clojure?

Leiningen doesn't work with local JARs, rather it requires the Maven coordinates for dependencies so that it can download those. I'd suggest you figure out the Maven coordinates of your WEB-INF/lib/*.jar files and specify those in project.clj Should you have local JARs not available on any Mave

Yes, this works. I added javax to dependencies, and the errors about this disappeared. But there is a lot of jars i used (in the WEB-INF/lib), how to add all these jars once and ever? i found jvm-opts -Djava.library.path, but i don't know how to use it 在 2015年5月27日星期三 UTC+8下午9:01:15，Shanta

Re: clojure edn function reader

I am not sure I understand your question. I will answer some questions with some of the same key words in them, and then you can decide if one of them was close to yours :) Clojure includes clojure.core/read [1] and clojure.core/read-string, which can read any Clojure code, but they can be danger

clojure edn function reader

Hey, I'm looking for an edn data read for clojure functions (similar to https://github.com/Datomic/day-of-datomic/blob/master/resources/day-of-datomic/clojure-data-functions.edn) Is there any known implementation? Thanks -- You received this message because you are subscribed to the Google G

Re: How to use a java web service project in clojure?

You should probably include the right dependencies in project.clj, e.g. :dependencies [[javax.ws.rs/jsr311-api "1.1.1"]] You might actually need an implementation, e.g. Apache-CXF, or RestEasy etc. as dependency but I am not sure. Shantanu On Wednesday, 27 May 2015 16:28:54 UTC+5:30, Peng Lin

Oh, my apologies. You also need to pass the request map to the render method. (-> (io/resource "public/html/confirm.html") (cr/render request) (resp/header "Cache-Control" "no-cache, no-store")) You could also write it as: (-> (resp/resource-response "public/html/confirm.

Hi guys, i'm new to clojure, and we have built our production using java. It's a web service, named "ddi", which runs on tomcat. i use eclipse to build a clojure project, and set in project.clj: :java-source-paths ["/Users/apple/ife/ddi/src"] then, set project.Properties.Lib

JSVC (Apache Commons daemon for Unix) is excellent for this sort of thing. There's a Windows Services version too. –S On Tuesday, May 26, 2015 at 12:38:30 PM UTC+1, Colin Yates wrote: > > Hi, > > I am venturing into new territory using http-kit, as I usually use a > 'managed' web server contain

Re: [Component] - Remove (dissoc) component from system

Hi Édipo, I'm not sure I understand the question. Why do you want to remove a component from the system after it has been started? Systems are just records, which behave like maps, so `assoc` and `dissoc` should work normally. But the process of starting a system creates copies of components t
