Question
I'm brand-new to both Emacs and Clojure and would like to set up hinting and syntax highlighting somehow similar to the video here. I have installed:
...Then within Emacs and via Marmalade, installed the following packages:
My big-idea question is how do these major/minor modes interact and is there a "right" way to set these things up?
My smaller-idea question is how do I get the pretty syntax highlighting and code-hinting?
Thanks!
Solution
Check out Emacs Live, its a full emacs configuration created by Sam Aaron. He codes allot of Clojure so this "battery included" setup works great for Clojure coding.
https://github.com/overtone/emacs-live
Once you have cloned this and follow the instructions you are up and running with Clojure, nrepl, git and much more.
OTHER TIPS
I list my setup. Some of the stuff is redundant, since I haven't written in Clojure for a while, but I checked and it still works.

Russianclojure to start nrepl.
You might have some issue with project.clj being in the appropriate directory,
but you should figure this out.foo.clj.nrepl-load-file
By the way, it's the canonical shortcut to load the file into inferior process.
It will work for Common Lisp, Python etc.Here's the setup code:
(require 'clojure-mode)
(defun set-syntax-parens ()
"highlight []{} etc."
(interactive)
(modify-syntax-entry ?[ "(]")
(modify-syntax-entry ?] ")[")
(modify-syntax-entry ?{ "(}")
(modify-syntax-entry ?} "){"))
(defvar clojure.jars '("clojure-1.3.0.jar"
"swank-clojure-1.4.2.jar"
"clojure-contrib-1.2.0.jar"))
(defvar clojure.jars.d (concat dropbox.d "source/clojure/lib/"))
(defvar clojure.classpath
(apply #'concat
(mapcar (lambda (jar) (concat clojure.jars.d jar path-separator))
clojure.jars)))
(setq clojure.classpath
(concat clojure.classpath
dropbox.d "source/clojure/include/"
path-separator))
;;;###autoload
(defun clojure ()
(interactive)
(nrepl-jack-in))
(defvar clojure-server-cmd
(concat "java -Xss4096k -cp " clojure.classpath " clojure.main &"))
(add-hook 'clojure-mode-hook
(lambda()
(set-syntax-parens)))
(require 'nrepl)
(add-hook 'nrepl-mode-hook
(lambda()
(define-key nrepl-mode-map (kbd "C-l") 'nrepl-clear-buffer)))
here is the operative section from my favorite emacs config:
(when (not package-archive-contents)
(package-refresh-contents))
;; Add in your own as you wish:
(defvar my-packages '(starter-kit starter-kit-lisp starter-kit-bindings clojure-mode
nrepl auto-complete ac-nrepl org rainbow-delimiters)
"A list of packages to ensure are installed at launch.")
(dolist (p my-packages)
(when (not (package-installed-p p))
(package-install p)))
(require 'ac-nrepl)
(add-hook 'nrepl-mode-hook 'ac-nrepl-setup)
(add-hook 'nrepl-interaction-mode-hook 'ac-nrepl-setup)
(eval-after-load "auto-complete"
'(add-to-list 'ac-modes 'nrepl-mode))
(defun set-auto-complete-as-completion-at-point-function ()
(setq completion-at-point-functions '(auto-complete)))
(add-hook 'auto-complete-mode-hook 'set-auto-complete-as-completion-at-point-function)
(add-hook 'nrepl-mode-hook 'set-auto-complete-as-completion-at-point-function)
(add-hook 'nrepl-interaction-mode-hook 'set-auto-complete-as-completion-at-point-function)
(define-key nrepl-interaction-mode-map (kbd "C-c C-d") 'ac-nrepl-popup-doc)
(add-hook 'prog-mode-hook 'auto-complete-mode)
(add-hook 'nrepl-interaction-mode-hook
'nrepl-turn-on-eldoc-mode)
(add-hook 'nrepl-mode-hook 'paredit-mode)
This turns on paredit-mode everywhere, which takes a bit of getting used to though it's entirely worth it because paredit and makes using Clojure much more fun. At least once you get a handle on slurping and barfing
