Extending Leiningen to Make it Do What you Want
summary
Explains how to add concrete Leiningen features: use aliases to run a project main (example: a DB migration that maps migrate → lein run -m clojars.db.migrate), use eval-in-project to run code inside the project JVM, and create plugins that hook into lifecycle via robert.hook to wrap tasks (example: cljsbuild wrapping compile) or inspect dependency resolution (line-pedantic aborts on downgrades). Covers prep-tasks, injections for embedding the project map into resources, and templates built with lein.new.templates and mustache sanitize rules.
