reasoning behind nth and take-nth inconsistent parameter pos.

Generally collection functions like conj, assoc, nth, get take the collection as the first arg and return a collection of the same type. The majority of the functions in the core lib are sequence functions working at a higher abstraction level - they take a seqable thing, call seq on it, and r

Re: Core.async, Rules for passing clojure vals to go block

Ok, got it. It was an oversight on my part. From a config file, I was pulling in *myns/myfn*. But this is just a symbol. I needed to resolve it, and deref the var that it pointed to. So now the below works. Tricky, but I should have caught it earlier. (apply @(resolve *afn*) params) Thanks guy

Re: Core.async, Rules for passing clojure vals to go block

Yes, good point. I tried apply, but the result from that is always *nil*(where there should be a value). You're right that it should work (we wouldn't use eval in that scenario), but it doesn't. I tried putting params in a seq a list and a vector, but no dice. I'm still playing around with it. T

Re: Core.async, Rules for passing clojure vals to go block

Amend what I said: your params would need to be something like `(... system-atom ...), or `(... a-namespace/system-atom ...), or `(... (:foo @system-atoms) ...). Then (eval `(~afn ~@params)) will splice that in and the resulting code will look up the appropriate Var (and then the appropriate map ke

Re: Core.async, Rules for passing clojure vals to go block

Your best bet is to move your "system atom" out to a top-level def, like so: (def system-atom (atom '({}))) Then just use (eval `(~afn system-atom)) later on, from places where the system-atom Var is visible (same ns, or :use'd), or use (eval `(~afn x/system-atom)) to qualify the name. The syntax

Re: Core.async, Rules for passing clojure vals to go block

The crux of the problem is that the size of *params* can be variable. Only at runtime, does the code match the loaded *afn*, with the passed in *params*. So I basically just need to break out the *~@params* into individuated input arguments. The only other way I can think to do that, without using

Re: Core.async, Rules for passing clojure vals to go block

Glad to help. I admittedly haven't taken the time to understand what's going on in your code, but whenever I see `eval` I feel compelled to ask: are you sure you need it? With that out of the way, here's a trick I've used to work around related errors: https://groups.google.com/d/msg/cloj

Re: Core.async, Rules for passing clojure vals to go block

Using a def inside a defn really shouldn't be done. Perhaps move the params to a let outside of the s/defn? Or change the def to a let? Timothy Baldridge On Fri, Jan 3, 2014 at 4:18 PM, Timothy Washington wrote: > Hey Jason, > > You were exactly right (which is pretty impressive, being that you

Hey Jason, You were exactly right (which is pretty impressive, being that you've never seen my code). In my (s/defn ..) form, there was an error that was failing silently. (s/defn [one two] ... *#_(def params (atom '({}) ))* (def params '({})) (try (eval `(~afn ~@params)) (catch Exce

Thanks for the report. Schema fns inside of go blocks seem to work fine for me. It seems likely that you're seeing an exception inside the go block, which is swallowed by default: user> (clojure.core.async/go (println "A")) # A user> (clojure.core.async/go (throw (RuntimeException.)) (printl
