(letfn [(create [k depth]
          (if (zero? depth)
            (k {:id depth})
            #(create
              (fn [c]
                (k {:id depth :child c}))
              (dec depth))))]
  (trampoline create identity 5000)
  nil)

shouldn't trampoline and using CPS prevent this from growing the stack?

for clarity, an example of using a depth of 5:

{:id 5, :child {:id 4, :child {:id 3, :child {:id 2, :child {:id 1, :child {:id 0}}}}}}

in fact, the non-trampoline version can actually grow farther lol

(letfn [(create [depth]
          (if (zero? depth)
            {:id 0}
            {:id depth
             :child (create (dec depth))}))]
  (create 5000)
  nil)

the answer is that I had an error in my trampolined version. the inner fn that calls k needs to return a thunk

(letfn [(create [k depth]
          (if (zero? depth)
            (k {:id depth})
            #(create
              (fn [c]
                (fn [] (k {:id depth :child c})))
              (dec depth))))]
  (dissoc (trampoline create identity 50000) :child))
;; => {:id 50000}

hmm but why is that necessary. k should return a thunk

What do people generally use for templates? Just simple text substitution stuff, not the sexpy html stuff

selmer https://github.com/yogthos/Selmer

or is this not what you were looking for

Maybe? Kinda? Seems there is also Cljstache. I tend to like Mustache implementations because of their simplicity. Seems Selmer is more advanced with filters and stuff. My needs are mostly glorified printf

I guess Selmer can also be used as glorified printf though, we'll see

@pepijndevos FWIW Selmer is also available in #babashka , but so is clojure.pprint/cl-format and format cl-format probably qualifies as a glorified version of format?

Hey, how does one get the final rendered html for a page using reagent?

@rbowen It is possible to use reagent.dom.server/render-to-string

Thanks @pavel.klavik, I'll give that a go.

I am trying to find a bizzare bug which only occurs in ClojureScript code compiled in advanced mode and only in Safari. After a fun evening of random debugging, I have found that it occurs in this function: https://orgpad.com/img/DpuNESB2FJbLm0P-eeYifP/download?token=AU25m6asVA56Cw6cceBK5Y The input a should be nil, but when passed into Lka, when printed there, it shows 0. When I copy this function on the side and add a log statement for the value of a, the issue disappears: https://orgpad.com/img/CwvFl3QIpCHL6IvsTpa3FJ/download?token=CsmOIOJNFKQ5t1VW8k7fFX

In Clojure, all three functions look like this:

All the inputs should be immutable Clojurescript values.
