This is a massive diff that I had to do in a hurry - when leaving Urbint. I'm pretty sure that most of these are updating Emacs packages, but I'm not positive.

;;; Commentary:

|
|
|
;; Smart code refresh functionality based on ideas from:
|
|
;; http://thinkrelevance.com/blog/2013/06/04/clojure-workflow-reloaded
|
|
;;
|
|
;; Note that refresh with clojure.tools.namespace.repl is a smarter way to
|
|
;; reload code: the traditional way to reload Clojure code without restarting
|
|
;; the JVM is (require ... :reload) or an editor/IDE feature that does the same
|
|
;; thing.
|
|
;;
|
|
;; This has several problems:
|
|
;;
|
|
;; If you modify two namespaces which depend on each other, you must remember to
|
|
;; reload them in the correct order to avoid compilation errors.
|
|
;;
|
|
;; If you remove definitions from a source file and then reload it, those
|
|
;; definitions are still available in memory. If other code depends on those
|
|
;; definitions, it will continue to work but will break the next time you
|
|
;; restart the JVM.
|
|
;;
|
|
;; If the reloaded namespace contains defmulti, you must also reload all of the
|
|
;; associated defmethod expressions.
|
|
;;
|
|
;; If the reloaded namespace contains defprotocol, you must also reload any
|
|
;; records or types implementing that protocol and replace any existing
|
|
;; instances of those records/types with new instances.
|
|
;;
|
|
;; If the reloaded namespace contains macros, you must also reload any
|
|
;; namespaces which use those macros.
|
|
;;
|
|
;; If the running program contains functions which close over values in the
|
|
;; reloaded namespace, those closed-over values are not updated (This is common
|
|
;; in web applications which construct the "handler stack" as a composition of
|
|
;; functions.)
