REPL :type command sometimes prints color highlighting characters literally

[deanwampler]

Minimized code

At the REPL prompt:

:type if (true) 1.0 else 2L

Output

(31m1.00m : Double) | (31m2L0m : Long)

Expectation

(1.0 : Double) | (2L : Long)

I observed this on OS X Catalina,, in both Terminal and iTerm.

It looks like typeOf already colorizes the literal types, and then :type munges the string with its highlighter pen.

I was hoping there was a quick way to say "give me a context with highlighting turned off while I perform an operation."

I tried just getting a "plain" printer but wound up with scala.this.Double badly colorized.

The PR just removes the highlighting; probably, printing the type could be made more colorful. But perhaps this will suffice to keep the issue counter from hitting 600.

I'm curios if this is now fixed? I can't seem to reproduce this and I'm also on OS X and using iTerm.

@ckipp01 this narrow issue is fixed by the linked PR. I don't remember why my PR doesn't say "fixes". Maybe because I was working on related string rendering and Scala 2 dragged heels on that PR?
