Access to unzipped assets within jars
Hi there, consider there exists foo.jar on Clojars which contains a bunch of asset files i.e. png images. If I were to declare foo as one of my project's dependencies, is it possible to get access to those asset files? I essentially want a path to a non-zipped version of each asset.

These kinds of assets are known as resources in java parlance. A resource is named by a path relative to an entry in the classpath. Declaring foo as a dependency will place it in the classpath. The name of the resource will therefore be the path of the asset within foo.jar. Give clojure.java.io/resource [1] that name, and it will return a URL. Pass that URL to clojure.java.io/input-stream [2] to open the resource for reading.

Sam, consider there exists foo.jar on Clojars which contains a bunch of asset files i.e. png images. If I were to declare foo as one of my project's dependencies, is it possible to get access to those asset files? I essentially want a path to a non-zipped version of each asset. I think `clojure.java.io/resource` will do the trick for you. You just need to know the path to the png file inside the JAR and as long as the JAR is in your classpath, you should be able to read it.

Re: Access to unzipped assets within jars
Interesting - thanks for this. So is it fair to assume that the JVM is ok with reading URL resources that are zipped in a jar. I also assume to have an actual non-zipped version of the resource I need to copy the file from inside the zipped jar to an external path in my file system?
