lambdaisland.witchcraft.classpath-hacks — com.lambdaisland/witchcraft 0.31.300

We do some classpath scanning stuff both in lambdaisland.witchcraft.reflect (which much of the interop is based on), and in [[lambdaisland.witchcraft.event]] (to find out which events are supported by the running system)

base-loader clj

(base-loader)

Get the loader that Clojure uses internally to load files

This is usually the current context classloader, but can also be clojure.lang.Compiler/LOADER.

class-resource clj

(class-resource classname)

context-classloader clj

(context-classloader)

(context-classloader thread)

Get the context classloader for the current thread

dynamic-classloader? clj

(dynamic-classloader? cl)

Is the given classloader a [[clojure.lang.DynamicClassLoader]]

inject-jar-by-class! clj

(inject-jar-by-class! klz)

Given a classname (string), find the .class file that defines it, then find the JAR that contains it, then add that JAR to the root classloader (i.e. the bottom-most clojure.lang.DynamicClassloader, which sits above the PluginClassloader). This ensures that any code that deals with the classpath can see the classes in these jars.

inject-jars! clj

priority-classloader? clj

(priority-classloader? cl)

Is the given classloader a [[priority-classloader]]

root-loader clj

(root-loader)

(root-loader cl)

Find the bottom-most DynamicClassLoader in the chain of parent classloaders

tracer-classes clj

Classes that are in jars that we care about
