<p class=MsoNormal>I am still having problems adding the BigDecimal method into
the Kernel module. As I understand it the correct method is to create a
new class that extends Kernel and adds the methods as both Private-Instance and
Public-Singleton. This is the code:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>namespace Ruby.StandardLibrary.BigDecimal {<o:p></o:p></p>
<p class=MsoNormal> [RubyModule(Extends = typeof(Kernel))]<o:p></o:p></p>
<p class=MsoNormal> public static class KernelOps {<o:p></o:p></p>
<p class=MsoNormal>
[RubyMethod("BigDecimal", RubyMethodAttributes.PrivateInstance)]<o:p></o:p></p>
<p class=MsoNormal>
[RubyMethod("BigDecimal", RubyMethodAttributes.PublicSingleton)]<o:p></o:p></p>
<p class=MsoNormal> public static
BigDecimal/*!*/ CreateBigDecimal(CodeContext/*!*/ context,
[NotNull]MutableString/*!*/ value, [Optional]int n) {<o:p></o:p></p>
<p class=MsoNormal>
return BigDecimalOps.CreateBigDecimal(value, n);<o:p></o:p></p>
<p class=MsoNormal> }<o:p></o:p></p>
<p class=MsoNormal>
[RubyMethod("BigDecimal", RubyMethodAttributes.PrivateInstance)]<o:p></o:p></p>
<p class=MsoNormal>
[RubyMethod("BigDecimal", RubyMethodAttributes.PublicSingleton)]<o:p></o:p></p>
<p class=MsoNormal> public static
BigDecimal/*!*/ CreateBigDecimal(CodeContext/*!*/ context, object value,
[Optional]int n) {<o:p></o:p></p>
<p class=MsoNormal>
return BigDecimalOps.CreateBigDecimal(context, value, n);<o:p></o:p></p>
<p class=MsoNormal> }<o:p></o:p></p>
<p class=MsoNormal> }<o:p></o:p></p>
<p class=MsoNormal>}<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This appears to create the methods (you can see them in
Kernel.methods) but it is not possible to call them. You always get
an ArgumentError thrown with “incorrect type or number of parameters” as a
message.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have been digging through the code but I can’t work out
why this is happening. One thing that seems a little worrying but not
necessarily wrong is that it appears that the target (self) has a RubyClass of
type Ruby.Builtins. BuiltinsLibraryInitializer, which seems rather bizarre.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Currently I am able to get around this by defining the
methods in Ruby itself, I changed the bigdecimal.rb file in the libs folder to:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>load_assembly 'IronRuby.Libraries',
'Ruby.StandardLibrary.BigDecimal'<o:p></o:p></p>
<p class=MsoNormal>class Object<o:p></o:p></p>
<p class=MsoNormal>
def BigDecimal(v, n = 0)<o:p></o:p></p>
<p class=MsoNormal>
BigDecimal.new(v,n)<o:p></o:p></p>
<p class=MsoNormal>
end<o:p></o:p></p>
<p class=MsoNormal>end<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas?<o:p></o:p></p>
