Endless Parentheses

Unite, fireplace, rainbow parens, vim-sexp and vim-surround are all available in Emacs with its own and better implementation.

If you want Unite equivalent, check Helm which is created before Unite and is still actively maintained. See one of Helm package demo: http://tuhdo.github.io/helm-projectile.html. The same for rainbow-parentheses. Actually, Emacs got something better than rainbow-parentheses for visual aiding parentheses: https://github.com/syl20bnr/spacemacs/issues/1173

For proper sexp manipulation, check this guide with great animations: http://danmidwood.com/content/2014/11/21/animated-paredit.html

For Clojure, in Emacs you got a debugger than can step expression by expression: http://endlessparentheses.com/cider-debug-a-visual-interactive-debugger-for-clojure.html

If you want to know features for Clojure that already configured in Spacemacs, check its Clojure documentation: https://github.com/syl20bnr/spacemacs/tree/master/contrib/lang/clojure#features

You got all IDE features like refactoring and jump to symbols

More demos:

Here are some nice features that Emacs and its 3rd packages provide:

- Powerful automatic indentation with aggressive-indent: https://github.com/Malabarba/aggressive-indent-mode(scroll down for demos). It does not only indent the current line, but the whole semantic context around your cursor.

- Live grep:http://tuhdo.github.io/static/live_grep.gif

- C/C++ refactoring with built-in parser:…

To save a google search, here's an emacs customization to leave cursor at the start of the match.

From http://endlessparentheses.com/leave-the-cursor-at-start-of-match-after-isearch.html

(add-hook 'isearch-mode-end-hook
#'endless/goto-match-beginning)
(defun endless/goto-match-beginning ()
"Go to the start of current isearch match.
Use in `isearch-mode-end-hook'."
(when (and isearch-forward
(number-or-marker-p isearch-other-end)
(not mark-active)
(not isearch-mode-end-hook-quit))
(goto-char isearch-other-end)))

I prefer keeping everything in one file (but exporting to separate files) so I hacked something up[1]. It doesn't build the index, but it would be pretty easy to extend to do so.

There's also Arthur Malabarba's extension[2] to ox-jekyll that's a much more complete solution.
