As I write more Elisp, I find myself using the threading macro increasingly often. However, since it is an imported, not a built-in one, the indentation is not like what I want it to be.
For example, I want the auto-indentation to be, not like this:
(->> '(1 2 3 4)
(mapcar #'1+)
(seq-filter #'evenp)
(reduce #'+))
but like this:
(->> '(1 2 3 4)
(mapcar #'1+)
(seq-filter #'evenp)
(reduce #'+))
...so that the inner expressions are aligned together vertically.
How can I specially designate the indent level, based on the expression's car
?
