Configurable threading

[Malabarba]

I always end up unwinding once after thread-first or thread-last. It would be nice to be able to specify a minimum depth or length of the first sexp in threading.

For instance, the following sexp

(remove #(< value 0) (filter :name (map :items return)))

Expands to this

(->> return
     (map :items)
     (filter :name)
     (remove #(< value 0)))

I'd like a way to say “the first line should be at least 1 level deep”, so it would end up like this:

(->> (map :items return)
     (filter :name)
     (remove #(< value 0)))

As an extra bonus, it would be nice to be able to specify a maximum length in characters for the first line. So that if the return variable has a very long name, it would still get its own line.

For instance, the following sexp

(remove #(< value 0) (filter :name (map :items the.ns/of-a-long-var-name)))

Would then still expand to this

(->> the.ns/of-a-long-var-name
     (map :items)
     (filter :name)
     (remove #(< value 0)))
