indent configurations in emacs cider/paredit/clojure-mode

Question

In an Emacs/Cider setup (which is build on top of clojure-mode and paredit-mode), tab stops are usually ignored. Or, say they indent just to the second symbol of an s-expression.

Sometimes, e.g for larger configurations, it's desirable to indent also the subsequent symbols:

This would be the default:

(def config [:hello 34 :goodbye
             :a 34 :c
             :long-word 0 :a])

What is to do, if it should look like:

(def config [:hello      34   :goodbye
             :a          34   :c
             :long-word  0    :a])

Is your config a vector? If it is map, [clojure-align](https://github.com/clojure-emacs/clojure-mode#vertical-alignment) should do the job. — OlegTheCat, Aug 19 '16 at 10:41
nice, this is good for maps. But actually I need it for vectors as well... — Anton Harald, Aug 19 '16 at 12:49

Emacs will not align the elements in vector as you wish, however, you can use M-i (tab-to-tab-stop) to insert tab (or multiple spaces depends on your config). So you can manually align the elements like the way you like.

that's good to have! It would be even better if clojure-align was enhanced to work with any collection. https://github.com/clojure-emacs/clojure-mode/blob/464c9de6734cb4b426137674041d695c2a7c7ef9/clojure-mode.el#L973 – Anton Harald Aug 19 '16 at 13:05
Feel free to file a ticket. We didn't consider such an usecase, but we might implement it in the future. – Bozhidar Batsov Aug 21 '16 at 15:58

If you can live with having your config as a map instead of a vector, clojure-mode does the right thing when you switch on clojure-align-forms-automatically:

(def config {:hello 34
             :goodbye [something else]
             :a [34 :c]
             :long-word 0
             :a 'b})

=>

(def config {:hello     34
             :goodbye   [something else]
             :a         [34 :c]
             :long-word 0
             :a         'b})
