multiple values px / generator

[ccfontes]

How do I write a generator like:

-moz-linear-gradient(top, #a90329 0%, #900000 44%, #6d0019 100%)

or a property with multiple px values like:

:padding "5px 0px 5px 50px"

any way more idiomatic than this?

How about :

(defn padding
  [t r b l]
  {:padding [[(px t) (px r) (px b) (px l)]]})

Or you could probably make it unit agnostic.

So the value of padding is a vector of a vector. looks strange, but I'm sure there were strong reasons!
How about the generator? Any idea?

[jeluard]

Well I guess the reason is there need to be some syntax to differentiate between the various CSS form you can find. See more details here.

In the linear-gradient case you could mix nested and non-nested vectors:

{:-moz-linear-gradient ["top" ["#a90329" (percent 0)] ...]}

@ccfontes Yes, it does look strange but that was the best idea I had when coming up with a way to represent the difference between comma and space separated lists. If you want you can write a function or macro to clean that up.

(defmacro defproperty [name]
  `(defn ~name [& params#] 
      {'~name [params#]}))

(defproperty padding)

(padding [0 1] [2 3]) 
;; => {padding [([0 1] [2 3])]}

Edit: Paste fail

Nah.. it's awesome!

@ccfontes There are also some other examples (unrelated) here.
