Or a Marilyn Monroe quote

I call shenanigans. This is horse twaddle. People can put anything in wikipedia, but it don't make it true. That is not a legitimate contraction. No sane Southener would contract the 'would' in that context. The smallest it'd get'd be "y'all wudnv". — Mitch yesterday

@JeroenVannevel Next profile: "I heard you like quotes."

Given a function that expects a number, would it make more sense to return false/null if the input is not a number, or to throw something like IllegalArgumentException?

Mast

Depends on what the function is doing.

If you're trying to divide a number and the input is not a number, I'd throw IllegalAE.

Splits a number into a list/vector of its digits

123 => (1,2,3)

return an empty list

Will it also split abc into (a, b, c)?

Quill

I always found it best to make those kind of functions passive

@Mast Negative

Mast

I'd throw it.

Prevent unexpected output.

Pin Crash

Now, making it return an empty list would still make it evaluate to true, while returning nil would eval to false

Mast

If somebody is doing something with your function your function shouldn't be doing in the first place, you should ask yourself whether you want to allow it. If not, throw.

That was my initial thought^ but was wondering if it would make sense

(defn explode-num-to-digits
  "Given a number N, returns a list of its separate digits.
  Throws IllegalArgumentException is N if not a number."
  [N]
  (try
    (if (number? N)
      ;; Does this one-liner need documentation or is it clear enough?
      (map #(Character/digit % 10) (str N))
      ;; else...
      (throw (IllegalArgumentException. "Input is not a number")))))

Looks pretty decent methinks

It'll be part of a bigger thing I'll put up for review later

@PinCrash exception

invalid input is exception

returning an empty list is how you'll end up with Javascript code

Pin Crash

lol gotcha

Q: DAL Naming conventions

I'm working on a new data access library (not ORM, but not as Spartan as Dapper either). In terms of naming conventions, which do you prefer: version 1 dataSource.FromTableOrView("Customer", new {CustomerKey = customerKey} ).AsModel<Customer>().Execute(); dataSource.FromTableOrView ("Customer", ...

Q: Merge sort through vectors C++

First off, thanks folks for the review. There are a couple of things that I want to accomplish here. I want to create a CLI program that takes two given size vectors, merge sorts them and then spits it out. My implementation compiles fine, but sometimes I get subscript out of range errors. This u...
