Good sources for Jenkins script library?

[David Karlsen]

I am currently investigating usage of Jenkins pipeline script library looking at

https://jenkins.io/blog/2015/12/03/pipeline-as-code-with-multibranch-workflows-in-jenkins/

https://www.cloudbees.com/blog/jenkins-workflow-using-global-library-implement-re-usable-function-call-secured-http-endpoint

and https://github.com/jenkinsci/workflow-cps-global-lib-plugin

Do anyone have good examples of global scripts? I found one real-world good source (e.g. not simple hello-world functions) in: https://github.com/fabric8io/jenkins-workflow-library/ - but would appreaciate even more sources.

Especially I am wondering if it's possible to pass a Map of arguments as well as a Closure to my function in vars/myFunction.groovy - as this would give the flexibility to pass config + body-closure, so that I can define some pre- and post- steps before and after the closure runs, using the passed configuration. The examples I find in https://github.com/fabric8io/jenkins-workflow-library/ all use the method body for passing parameters - thus leaving no "space" for a closure.
