@jaen: yea, don't know. My experience has been the exact opposite.

And I haven't needed a debugger in Clojure at all-- just test small snippets in REPL and paste them into source file. If something doesn't work, then I just use println/console.log

@johanatan: That's my experience too. I never use a debugger in Clojure, although it's possible now. I do use it in Ruby though, binding.pry.

what is the Ruby equivalent of apply?

say I've got a method foo(*v), and I want to call it with an array

probably Ruby has magic for this...

@borkdude: try send(:foo, v)

just foo(v) works (Ruby magic ...)

To answer your original question though, foo(*v) is the equivalent of JS apply (it expands the array v to match the args accepted by foo)

* is the “splat” operator, which converts an arg list into an array and vice versa.

does the same for keyword args

ok

What is a good name for a function that calculated the price after a possible reduction

@borkdude discount-price ?

That’s good. Or price_after_discount.

@nilbus: I only read this now, but that's exactly what I chose

@nilbus: @agile_geek I didn't tell you this was Ruby, so _ is more appropriate

yay for my last-second realization and edit 😉

@nimbus @borkdude as discount is a verb as well as a noun I thought discount the price i.e. discount_price was slightly better than price_after_discount which sounds like a field not a function? Happy to be contradicted tho

in this case it's actually a method on a model object

a field-like name for a method is good and normal in ruby

as long as there are no side effects

sounds good

could have used discounted_price as well

yes

another good option

thanks guys
