Unfill Paragraphs in Emacs emacs

Quite often I like my texts broken up to some line width. Some forms require paragraphs to be without newlines though, so I have to convert the text back to unjustified form. As I'm using Emacs heavily, this elisp snippet comes in handy sometimes:

(defun unfill-paragraph ()
  (interactive)
  (let ((fill-column 9999999))
    (fill-paragraph)))

Run Limboole From Org-Mode emacs

I really like Org Babel's Execute feature, using C-c C-c. The following snippet implements an execution function for limboole. Just start a limboole source-block and optionally add :mode, with valid values being sat or validity. It internally just checks for the first character, so s or v are also okay. By default, it behaves like limboole and executes the validity check.

(defun org-babel-execute:limboole (body params)
  "Execute a block of Limboole code with org-babel. Takes the
parameters :mode satisfiability and :mode validity."
  (let ((mode (assoc :mode params)))
    (when (not mode)
      (setq (mode (cons :mode "v"))))

    (setq mode (cdr mode))

    (message "executing limboole source block, mode %s" mode)
    (org-babel-eval (s-concat "limboole "
                              (cond
                               ((s-starts-with? "s" mode) "-s")
                               ((s-starts-with? "v" mode) "")
                               (t (error ":mode must either be sat or validity")))) body)))
