internal error when incorrectly casing member

[gauthier]

I get internal error when compiling this code

class WritingStuff
    def doThat
        tw = StringWriter()
        tw.writeline #this is generating the error

class Test
    def main is shared
        w = WritingStuff()
        w.doThat

By the way, is there a compiler trace feature that output each line number before an internal exception occurs or such functionality? I got this bug in a 500 line file and it would help to track down where the parsing choke.

Yes, there seems to be something rather wrong about StringBuilder.writeline.

The following fails too (and produces the longest error message I've ever seen):

class Test
    def main is shared
        StringWriter().writeline('')

Interestingly, this works:

class Test
    def main is shared
        StringWriter().write('')

that's all it takes to catch typo, the actual method name is WriteLine so it should called writeLine!

That's weird, I would've expected a more "friendly" error from the cobra compiler for such a simple error (misspelling a method's name)

So it looks like I was of help even if that wasn't my intention

I'll take a look later today. Have to bust out the rent right now...

Fixed in changeset:1824.

-- The internal error messages are now truncated to 1024 chars.

-- This bug happened if you (1) spelled the member name correctly, (2) got the case wrong and (3) it was a member overload.

-- Regarding the line number, we have this for internal errors in the parser but not for the subsequent phases of the compiler.

Wow, that was some ace bug finding on gauthier's part
