[MacRuby-devel] CorePlot success?

[Russ McBride]

Merci Laurent.  That's progress.  I generated a BridgeSupport file.


Now, I'm getting this:
>> theme = CPTheme.themeNamed(KCPDarkGradientTheme)
=> #<CPDarkGradientTheme:0x200621300>


But now:
>> z = CPDecimalFromFloat(4.1)
Assertion failed: (size > 0), function convert_type, file compiler.cpp, line 5803.
Abort trap

CPDecimalFromFloat and friends are not inline functions so I don't need to generate a dylib file, as far as I can tell.

And:
>> xLow = 0.0
=> 0.0
>> xLow = NSNumber.numberWithFloat(xLow.to_f).decimalValue
=> #<NSDecimal:0x20055fc60>
>> fDays = 398.0
=> 398.0
>> fDays = NSNumber.numberWithFloat(fDays.to_f).decimalValue
=> #<NSDecimal:0x2005ebe60>
>> xrange = CPPlotRange.plotRangeWithLocation(xLow, length:fDays)
Assertion failed: (size > 0), function convert_type, file compiler.cpp, line 5803.
Abort trap


Cheers,
russ

This could explain why MacRuby cannot use the CPDecimalFromFloat() C function or the kCPDarkGradientTheme C constant (note that it must be called KCPDarkGradientTheme from MacRuby, as constants must always start with a uppercase letter).
