prototype.worksheet.sc non procesable?

[jftavira]

I've been trying to execute prototype.worksheet.sc in Scala 3 but i'm having some errors like this one:

scala> def I2OSP(i: BigInt, len: Int): OS = Array.fill[Byte](len - i.os.length)(0) || i.os -- [E008] Not Found Error: ----------------------------------------------------- 1 |def I2OSP(i: BigInt, len: Int): OS = Array.fill[Byte](len - i.os.length)(0) || i.os | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | value || is not a member of Array[Byte] 1 error found

Is "||" the logical "OR" really the operation needed? https://www.tutorialspoint.com/scala/scala_operators.htm

Hi Juan, thank you for raising this issue. In 97fc16c I have:

• specified the Scala version to use, to be sure;
• moved up the definition of extension (b: OS) infix def ||(c: OS) = b concat c: indeed I meant concatenation and not logical OR.

Now it should run well in:

• Scala CLI: scala-cli run prototype.worksheet.sc
• Visual Studio Code with the Scala (Metals) extension (but not sure how to force a specific Scala version)
• Scastie: https://scastie.scala-lang.org/LFNuYtC1TWGUQ7U6y1mptg

Correct, I was able to run it in IntelliJ at least
