[Ironruby-core] Overriding CLS Virtuals

I''ve committed some changes to IronRuby (in SVN revision 141) that let
you implement CLS interfaces and override virtual methods on CLS base types. 
Interfaces work like Ruby modules, so to make your class implement IDisposable
you could say

require ''mscorlib''
class Disposable
  include System.IDisposable
  def Dispose
    # Do something
  end
end

You can also override virtual properties.  A class or interface that has the C#
declaration "string Value { get; set; }" is overridden from IronRuby
with methods named "Value" for the getter and "Value=" for
the setter.

Note that you need to use the same casing as the CLS definition for both methods
and properties.

We''re just getting started with better .NET interop support and
don''t have very much test coverage yet - but this should let you get
going on some more sophisticated interop scenarios than were previously
possible.

Oops... that should have said "include System::IDisposable".  My

Mysteriously broken calls to dispose?

I don''t seem to be able to call Dispose on a filestream. Needless to
say this is problematic.

Here''s a paste, straight from the IR console (latest svn version 141)

&gt;&gt;&gt; require ''mscorlib''
=&gt; true
&gt;&gt;&gt; include System::IO
=&gt; Object
&gt;&gt;&gt; $fs = FileStream.new( ''file.txt'',
FileMode.Open )
=&gt; #
&gt;&gt;&gt; $fs.Dispose
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\matchcaller.generated.cs:30:in
`Call2'': wrong number or type of arguments for `Dispose''
(ArgumentError)
        from
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\callsite.cs:275:in
`UpdateAndExecute''
        from
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\updatedelegates.generated.cs:38:in
`Update2''
        from :0
&gt;&gt;&gt;

All the other methods on the filestream object work fine
(read_all_text, and so on), but the call to dispose crashes.

Likewise, I get a crash calling methods with overloads, which looks
like it may (??) be related.

&gt;&gt;&gt; require ''mscorlib''
=&gt; true
&gt;&gt;&gt; include System::IO
=&gt; Object
&gt;&gt;&gt; $bytes = System::IO::File.read_all_bytes(
''file.txt'' ); nil  # nil is to prevent ir from printing the
GIANT ARRAY
=&gt; nil
&gt;&gt;&gt; $text = System::Text::Encoding.UTF8.get_string($bytes)
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\matchcaller.generated.cs:35:in
`Call3'': wrong number or type of arguments for `get_string''
(ArgumentError)
        from
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\callsite.cs:275:in
`UpdateAndExecute''
        from
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\updatedelegates.generated.cs:45:in
`Update3''
        from :0

&gt;&gt;&gt; $text = System::Text::Encoding.UTF8.get_string($bytes,
0, $bytes.length)
=&gt; "PROPER TEXT GOES HERE"

It seems like it can''t figure out that there is GetString(bytes) and
GetString(bytes, index, length) and just uses the latter always.

Is there a solution for either of these problems?

Thanks a lot, Orion

[Ironruby-core] Overriding CLS Virtuals

Are we planning on supporting name mangling to give more Ruby-ish names? Like
will we be able to do "def dispose" instead of "def

[Ironruby-core] Mysteriously broken calls to dispose?

Yes, this has been reported before (in fact, I think it was when someone was
writing "using" ?) and we haven''t yet worked out a
resolution.  I''ll see if there''s something quick that can be
fixed here later today.

[Ironruby-core] Mysteriously broken calls to dispose?

yep that is correct :)

http://github.com/casualjim/ironnails/tree/master/IronNails/vendor/iron_nails/lib/core_ext/kernel.rb

I figure you can wrap that in a begin..rescue block again and first try the
one with the bool and then the one without it.
Some implementations of Dispose don''t actually implement the method
with a
bool as parameter.

Instead of FileStream you can use the ruby File class or you could write a
FileStreamAdapter in C# or something so you can safely use it from IronRuby
without the overloading mayhem.

Cheers
Ivan

[Ironruby-core] Overriding CLS Virtuals

When you override a virtual method you''re pushing much more into
CLR-world than when you''re just calling some function on some method. 
In the latter case, you shouldn''t have to know that the function
you''re calling is actually defined outside of Ruby, while in the
former, this is a fairly important piece of information.

In any event, I recall that both John and Tomas felt that we shouldn''t
-- but no longer remember all the details.

[Ironruby-core] Mysteriously broken calls to dispose?

Well, the interface itself only contains the parameterless method.  The version
with the parameter is part of a very common pattern that also optimizes the
finalization experience and plays nicely with derived classes.  If
you''re really concerned about cleaning something up, you''ll
probably follow that pattern.  But if you''re just interested in the
syntactic sugar of "using" and/or never expect the object''s
lifespan to exceed that of the current method, then there''s no real
need to implement the additional two methods or pay the cost of having a
finalizer.  (Even if you suppress it later, creating an object with a finalizer
is more expensive than creating it without one iirc.)

IDisposable is one of my favorite topics.  I believe that officially makes me a
masochist.

All the other methods on the filestream object work fine (read_all_text, and so
on), but the call to dispose crashes.

Likewise, I get a crash calling methods with overloads, which looks like it may
(??) be related.
>>> require ''mscorlib''
=> true
>>> include System::IO
=> Object
>>> $bytes = System::IO::File.read_all_bytes(
''file.txt'' ); nil  # nil is to prevent ir from printing the
GIANT ARRAY
=> nil
>>> $text = System::Text::Encoding.UTF8.get_string($bytes)
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\matchcaller.generated.cs:35:in
`Call3'': wrong number or type of arguments for `get_string''
(ArgumentError)

        from
c:\development\ironruby\trunk\src\microsoft.scripting.core\actions\callsite.cs:275:in
`UpdateAndExecute''

        from

`Update3''

        from :0

>>> $text = System::Text::Encoding.UTF8.get_string($bytes, 0,
$bytes.length)
=> "PROPER TEXT GOES HERE"

It seems like it can''t figure out that there is GetString(bytes) and
GetString(bytes, index, length) and just uses the latter always.
Is there a solution for either of these problems?

Thanks a lot, Orion

When you override a virtual method you''re pushing much more into
CLR-world than when you''re just calling some function on some method. 
In the latter case, you shouldn''t have to know that the function
you''re calling is actually defined outside of Ruby, while in the
former, this is a fairly important piece of information.

In any event, I recall that both John and Tomas felt that we shouldn''t
-- but no longer remember all the details.

The Java convention is that method names start with lower-case characters, so I

[Ironruby-core] Overriding CLS Virtuals

I saw a presentation that (if I remember correctly) showed methods like doFoo
becoming do_foo. So I think they mangle method names. I don''t know if
they do this for interface methods, which is closer to this problem.

Ask, and ye shall recieve.
jruby 1.1.4 on JDK 1.6:

Java Code:

public interface ISayer {
        public void say(String foo);
        public void sayMultipleThings(String foo, String bar);

public class SayThings {
        public static void sayThings( ISayer sayer ) {

                sayer.sayMultipleThings("Saying Multiple",
"Things From Java");
        }
}



Ruby Code:

require ''java''

$CLASSPATH << ''.''

class RubySayer
        include Java::ISayer

        def say(word)
                puts "FROM RUBY: #{word}"

        def say_multiple_things(first, second)
                puts "FROM RUBY: #{first}, #{second}"
        end
end

rc = RubySayer.new

Java::SayThings.say_things( rc )



When Run:

FROM RUBY: Invoked from java
FROM RUBY: Saying Multiple, Things From Java


Aside: Every time I go near java, CLASSPATH and
''one-class-per-file'' makes me want to go outside and hit
something. IronRuby isn''t even finished yet and already I''d
much rather use it :-)

require ''java''

$CLASSPATH << ''.''

class RubySayer
        include Java::ISayer

        def say(word)
                puts "FROM RUBY: #{word}"
        end

        def say_multiple_things(first, second)
                puts "FROM RUBY: #{first}, #{second}"
        end
end

rc = RubySayer.new

Java::SayThings.say_things( rc )



When Run:

FROM RUBY: Invoked from java
FROM RUBY: Saying Multiple, Things From Java


Aside: Every time I go near java, CLASSPATH and
''one-class-per-file'' makes me want to go outside and hit
something. IronRuby isn''t even finished yet and already I''d
much rather use it :-)

they do this for interface methods, which is closer to this problem.

The Java convention is that method names start with lower-case characters, so I
don''t imagine that there''s any special handling being
performed.

I know their naming convention is different, but lets see what JRuby does too.

When you override a virtual method you''re pushing much more into
CLR-world than when you''re just calling some function on some method. 
In the latter case, you shouldn''t have to know that the function
you''re calling is actually defined outside of Ruby, while in the
former, this is a fairly important piece of information.

In any event, I recall that both John and Tomas felt that we shouldn''t
-- but no longer remember all the details.

Are we planning on supporting name mangling to give more Ruby-ish names? Like
will we be able to do "def dispose" instead of "def
Dispose"?

[Ironruby-core] Overriding CLS Virtuals

Are we going to have "real" properties under the hood, because what we
have
for now is just method with "get_PropertyName"? And this did not play
nicely
with databinding.

I think the same question applies for events as well.

[Ironruby-core] Overriding CLS Virtuals

Right now, the only way to get properties is to implement an interface that
defines them.  When IronRuby supports this "natively", it will have to
define a syntax for doing so.  That''s because the Ruby language
supports neither properties, attributes nor static types - all of which will be
needed.  This will probably involve adding some new methods to Class that allow
you to define typed CLS members.  But we don''t have a specific
timeframe for implementing this yet.

2008/9/9 Curt Hagenlocher <curth at microsoft.com<mailto:curth at

I''ve committed some changes to IronRuby (in SVN revision 141) that let
you implement CLS interfaces and override virtual methods on CLS base types. 
Interfaces work like Ruby modules, so to make your class implement IDisposable
you could say



require ''mscorlib''

class Disposable

  include System.IDisposable

  def Dispose

    # Do something

  end

end



You can also override virtual properties.  A class or interface that has the C#
declaration "string Value { get; set; }" is overridden from IronRuby
with methods named "Value" for the getter and "Value=" for
the setter.



Note that you need to use the same casing as the CLS definition for both methods
and properties.



We''re just getting started with better .NET interop support and
don''t have very much test coverage yet - but this should let you get
going on some more sophisticated interop scenarios than were previously
possible.
