Cobra Internal Error

Postby torial » Wed Mar 16, 2011 7:57 pm

When I incorrectly use an Enum ,

textBox.anchor = textBox.anchor or AnchorStyles.Right


I get the following Internal Error:

error: COBRA INTERNAL ERROR / FallThroughException / info=TruthExpr-sh(75266, didBindInh=false, didBindInt=false, didStartBindImp=true, didBindImp=false, token=Token(DOT, '.', '.', ln 52, col 33, C:\Users\seanm\Desktop\Cobra\IDE\Utils.cobra), Treatment=AsIs, type=nil, 75266)


A better messages would be anything from a generic "syntax error at line 52", to "incorrect enum operation, try |" or something like that. Should I write a bug up?

Looks like we have it in ticket:265 although a different bit of code produced it. Of course, if we fixed the use of enums as truth values to just work then your OR expression becomes valid even though it's clearly not what you intended.

I've added this discussion to the ticket.

This will now give the error message:

Cannot treat enums as truth values. Compare them to a value with "==" or "<>", or if they are flags, use a bitwise operator ("&", "|", "~").
