clojure-conj-talk

Here is are the code examples used in the 2013 Clojure Conj talk on core.async. The core.clj file in this project contains the examples, and expects that users will eval the forms one at a time, top to bottom.

Usage

In the talk, I used a binding (CTRL-`) and this emacs code to run each form one at a time in a repl.

(defun nrepl-eval-expression-at-point-in-repl ()
  (interactive)
  (let ((form (nrepl-expression-at-point)))
    ;; Strip excess whitespace
    (while (string-match "\\`\s+\\|\n+\\'" form)
      (setq form (replace-match "" t t form)))
    (set-buffer (nrepl-find-or-create-repl-buffer))
    (goto-char (point-max))
    (insert form)
    (nrepl-return)))

If you are using CIDER below is the equivalent.

(defun cider-eval-expression-at-point-in-repl ()
  (interactive)
  (let ((form (cider-sexp-at-point)))
    ;; Strip excess whitespace
    (while (string-match "\\`\s+\\|\n+\\'" form)
      (setq form (replace-match "" t t form)))
    (set-buffer (cider-find-or-create-repl-buffer))
    (goto-char (point-max))
    (insert form)
    (cider-repl-return)))
