Unintended behaviour with toPrintString on char type?

[Ourous]

It seems that incorrect strings are generated when toPrintString is called on a char inside an enumerable.

Reproducible here:

class Demo
    def main
        print [c'\n']

Expected output:

Code: Select all

[c'\n']


Actual output:

Code: Select all

I've been able to fix it by overriding the charToString method of CobraCore.PrintStringMaker with this:

def charToString(c as char) as String is override
    if .level == 0
        return c.toString
    else
        return .charToCobraLiteral(c)
