Is "write a program" accurate?

[petertseng]

We have a lot of descriptions that say "write a program". As exercism/exercism#2746 explains, this may set up a wrong expectation from students that they are writing e.g. something with a main function (or equivalent entry point in language of choice).

But it seems that most tracks I've seen simply ask the student to write a function. Most languages then verify the behavior with unit tests against that function.

In the interest of setting up expectations correctly, shall we replace "write a program" with "write a function"?

Things I would like to check before doing that:

• Are there any tracks that do, in fact, expect the student to write a full-fledged program?
• Are there any tracks in which the equivalent concept is not called a function? (Perhaps it's called a procedure instead? Or something completely different?)
  • Even if there aren't, what if we add such a track in the future?
  • If there currently are or could be in the future, should we do anything about it? In other words, do we decide that we'll simply use a "function" as a generic terminology, regardless of how this concept maps onto the target language?

Anything else I'm missing?

Perhaps "write a program" is the most generic way to address this? In the case of Ruby, I don't think I have yet to see a "Write a method" request, on its own, the final result is usually a class or a module, and many solutions don't require either, which is perfectly fine with me. It leaves the implementations open.

Most generically, it may be "write instructions" to accomplish something.

Once you ask for a function or procedure or method, you are probably being too specific, even the tests in many cases may be considered too specific, driving a certain way to solve something, which may be impossible to avoid, or just may be hard to avoid.

What were if we ask for writing a library? This leaves everything open
while not suggesting the io stuff.

"write some code"?

(Library sounds big and scary.)

[kotp]

"Write code" sounds cryptic... just kidding. But yeah, the same "generic" flavor.

[petertseng]

I agree that library seemed potentially too large in scope. It's admitted to me that there are some tiny libraries, but maybe such a thing would not be as apparent to students.

"Write code" seems suffciently generic. I think I would prefer it to "write a function".

Here is another possible suggestion I have: Just remove the words completely. As an example, binary-search, before:

Write a program that implements a binary search algorithm.

Binary search, after:

Implement a binary search algorithm.

Seems to avoid duplication if every exercise has "write code" in common

[kotp]

I agree with this, the removal allows the "obvious" interpretation regardless of terms the individual user should choose to replace with the implied statement. We don't care if they write it or craft it or conjure it, whatever it is, as long as the tests pass and they get the learning experience from it. (And even the tests passing are only a guide and a common reference, in their experiences context.)

[kytrinyx]

I like the idea of removing the words where possible, and if not, go with a super generic "some code" to avoid the but this is not an X argument.

Here's a PR for this: #528

[kotp]

Looks like it was merged in, so closing.

[robkeim]

Thanks @kotp I forgot to close this.

[kotp]

No problem. Don't forget that if there is a "fixes #000" in the commit, it will do so automatically when they are brought in.

[robkeim]

Thanks for the explanation @kotp. I had "addresses #000" in the commit, so it didn't pick that up as a keyword.
