Boot for Leiningen Users

All of the different abstractions used to control how Leiningen works ([plugins], profiles, middleware, and injections)

Profiles, Middleware

The equivalent of Leiningen profiles and middleware in boot are tasks that modify the environment and return clojure.core/identity, the no-op task middleware.

For example, a task to add the test directory to the :source-paths when running tests, similar to the test profile in Leiningen:

(deftask testing
  "Profile setup for running tests."
  []
  (set-env! :source-paths #(conj % "test"))
  identity)

Profiles are "activated" simply by adding them to the pipeline, for example:

$ boot testing run-tests

This is equivalent to Lein's

$ lein with-profile testing run-tests

Lein Pprint

The equivalent of lein pprint in boot is:

boot show -e
