SICMUtils, 2

.

The goal of this post to setup the Emacs editor for Clojure programming.

.

1. Read and follow the exact steps of the last post.

.

2. Open the .emacs file. Go to the end of the file. Add the following code:

(require 'org)
(require 'ob-clojure)

(setq org-babel-clojure-backend 'cider)
(require 'cider)

(set-register ?c '(file . "~/my-stuff/my-stuff.org"))

(setq org-confirm-babel-evaluate nil)

(setq org-src-tab-acts-natively t)

3. Close Emacs.

.

4. Go to the directory “~/my-stuff/” and then create a file named “my-stuff.org“.

5. Use Emacs to open the file.

6. Within the file, add the following code:

#+BEGIN_SRC emacs-lisp

  (+ 1 1)

#+END_SRC

7. Place the text cursor in the code block (between the line #+BEGIN_SRC and the line #+END_SRC).

8. Hit the Emacs command

C-c C-c

9. You will get the evaluation result:

#+RESULTS:
: 2

.

10. Hit the Emacs command:

M-x cider-jack-in

11. Within the file “my-stuff.org“, add the code:

#+BEGIN_SRC clojure :results value		  

  (require '[sicmutils.env :as env])

#+END_SRC

12. Place the text cursor in the code block.

13. Hit the Emacs command

C-c C-c

.

14. Add the code:

#+BEGIN_SRC clojure :results value		  

  (env/bootstrap-repl!) 

#+END_SRC

15. Place the text cursor in the code block and then hit the Emacs command

C-c C-c

.

16. Add the code:

#+BEGIN_SRC clojure :results replace drawer
 
(->TeX (simplify ((D cube) 'x)))
 
#+END_SRC

17. Place the text cursor and then hit

C-c C-c

It will give you the code

#+RESULTS:
:RESULTS:
"3\\,{x}^{2}"
:END:
