hmm any good util for building element class names based on predicates?

What do you mean @minikomi

ah, I had a bunch of values which, if not nil, I wanted certain classes appended to the main wrapper to control css/appearance ended up writing a macro, because some of the class names depended on the values being derefed (eg (name @background-type) ) takes pairs of [predicate classname], builds a space separated string

I think you can apply a vector as :class, but would have to verify

oh really? then i could just do like (and @value (str "something-" (name @value))) since and short circuits..

You could use clojure.string/join and filter for nil? befote hand. Also the cond-> threading macro may be fun

For extra brevity use some->>

yeah i had that style originally, but thought there might be a more compact way to do it

hmm .. seems a vector joins the words by ,.. it does filter nil though.

Hmm too bad

Would be a nice enhancement though, maybe

Is an example of the cond-> option

I personally filter for nil? And then do a string/join

ooh cond-> looks pretty close to what i wanted, thanks
