How can I call Java methods from existing Maven libraries (and their dependencies)?

Is there an example, how to use a JSR 223 Scripting language from within clerk?

These seem like general Clojure questions rather than Clerk-specific ones. I recommend you have a look at the Clojure documentation. :)

Thank you, I will look there again.

But the idea I have in mind, will be a "meta description of dependencies" similar to JBang

• https://www.jbang.dev/documentation/guide/latest/index.html

which loads Java libraries from Maven Central (or local repository)

These libraries are "prepared with a clerk/clojure interface definition" (for example in a manifest file definition in the JAR), which can use the output formats from clerk by running a "script command" defined in the library.
There are so many Java libraries which could easily be reused in such an environment.

As an example JSR223 uses such a javax.script.ScriptEngineFactory Factory definition for the scripting:

There is a mechanism for loading libraries from Maven, local jars, git repos, &c, in Clojure already:

Yes, how about the missing part of calling a JSR223 script engine via eval()method?

Example:

ScriptEngine#eval("Plot(Sin(x),{x,-10,10})");

and creating clerk plotting output formats?
