optional parameters in functions

[chris]

Hi:

Are optional parameters allowed in non-target functions allowed in
aardvark? The following simple vark file reports errors:

function targetUsingOptionalValue() {
withOptionalParameter("some parameter")
}

function targetSpecifyingValue() {
withOptionalParameter("some other param", true)
}


private function withOptionalParameter(required_param : String,
bg=false) {
print("Hello: ${required_param} - ${bg}")
}


Wrong number of arguments to function
withOptionalParameter(java.lang.String, boolean). Expected 2, got 1.
[line:3 col:25] in
line 2: function targetUsingOptionalValue() {
line 3: withOptionalParameter("some parameter")
line 4: }
Line Number: 3 Column: 25

Thanks

Chris

I think you need to specify the type of your optional parameter:

private function withOptionalParameter(required_param : String,
bg : boolean = false) {

Yeah, I tried that with the same result. The code does work as is if its a gsp file (gotta love type inference) and I call one of the functions.

It might be a vark issue, rather than a gosu issue.  I don't know what version of gosu the current release of vark is using...

Hm, I see this issue in 0.3.2, but somehow things are fine in my bleeding edge 0.3.3 build, both with and without the parameter type.  Hang on, and I'll follow up on the other thread so that you can build 0.3.3 from source.

Maybe a bug fix in Gosu?

Yeah looks like the problem goes away with the latest aardvark from
git.
