im having problems passing in a string to a function. The println on that string appears to be "nil" but when i run println on the string outside of the function the string is actually a string. Anyone have any insight here?

why would println work but not (#(println %&))

I feel like im taking crazy pills

lol

did you solve?

Why not just use (println _var-name_)? The way you’re doing it isn’t idiomatic. Furthermore you’re not passing anything to println there.

Im not actually trying to print the variable, I want to write it to a file

but as a sanity test - the println does not work

the prinln in a function doesnt work

Right, because you’re not passing it anything in that function call. You mean something like (#(println %) _var-name_).

No, I want a function that takes in a variable

I am trying to use this

https://github.com/skeuomorf/udp-wrapper

the recieve-loop function takes an input function

the example they use is println

i want to swap out println with a file io function

hi, clojurists!

best way to extract coordinates from a 2D array where a value is the one needed?

@bfast, why not just pass println? That’s what it seems to be expecting, looking at the source.

say, I want all the coordinates of the values '2' in my 2D array... should I try to get them with two nested keep-indexed?

akiva, I want to swap out println so I can write it to a file instead of standard out

Fair enough. def a partial for spit and pass that in.

(def print-to-file (partial spit _file-name_).

ok...

thanks for your help @akiva

I still dont understand why my initial approach wouldn't work

Because the anonymous function is complete with the closing parens. The results aren’t included inside the form containing the anonymous function so the #() never sees it.

ok i see

Anytime. Gotta run.

any ideas on the best way to remove first 2 bytes of a clojure string?

Hi everyone! I'm using the reloaded workflow. How can I exclude individual namespaces from being reloaded? I have created a file/namespace in my projects 'dev' folder where I put my repl code (using fireplace). I don't want that to be reloaded.

As context: http://thinkrelevance.com/blog/2013/06/04/clojure-workflow-reloaded

@andreas-thoelke: (clojure.tools.namespace.repl/disable-reload!)

use that fn on the ns that you dont want to be reloaded

What does :- mean?

It's just a keyword.

What's the context? Midje?

@seancorfield: ^ the context is this code from #C051WKSP3

ah ok, so just a keyword. so no different then :dash

That's Schema annotations. But yeah, it's just a keyword.

Schema supports arg-name :- Type in arguments.
