The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502

An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

• 🔴 Mandatory (for both beginners and intermediates)
• 🟩 For beginners
• 🟨 For intermediates

(defvar ct/org-created-property-name "CREATED"
  "The name of the org-mode property that stores the creation date of the entry")

(defun ct/org-set-created-property (&optional active NAME)
  "Set a property on the entry giving the creation time.

By default the property is called CREATED. If given the `NAME'
argument will be used instead. If the property already exists, it
will not be modified."
