[Ironruby-core] Ruby code from C-Sharp; String.split() with rbx

Hi all,

 

I am playing around with IronRuby for a week now and have 3 questions/issues
that I sincerely hope you have some nice comments or solutions for.

Thanks for reading. I appreciate it.

Cheers,

Stefan

 

 

FIRST ISSUE

============================
I try to call some ruby code from a c# file. My first attempt was this:

1 RubyEngine re = RubyEngine.CurrentEngine;

2 re.ExecuteCommand("s = ''let us get started''");

3 re.ExecuteCommand("i = s.length");

 

Problem and question:

I think each line is executed as a block, so that the second time I try to use
s it is undefined and I get an exception. If s is global it works. 

Is there a way to tell the RubyEngine to kind of collect Commands and then
execute them as one single block?

 

 

SECOND ISSUE

============================
My second attempt to call ruby code from a c# file was this:

1 RubyEngine re = RubyEngine.CurrentEngine;

2 re.ExecuteCommand("require
''C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\mscorlib.dll''");

3 re.ExecuteFileContent("c:\\myRubyFile.rb");

 

myRubyFile.rb is:

1 require
"C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\mscorlib.dll"

2 require
"C:\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50727\\System.Windows.Forms.dll"

3 sr = System::IO::StreamReader

4 sr = System::IO::File.OpenText("c:\\atlog.txt")

...

 

Problem:

Just executing the ruby file is not much of a problem; so calling ruby that in
turn calls the CLR works fine. But, if I include line 2 of the c# code above I
get the exception below, not telling me which file couldn''t be found.
Removing
line 2 brings me back to a running program. So I think with requiring a dll
twice is a problem. Should it be??

I tried to debug this behavior. I set up the ironruby and Microsoft.scripting
project in VS2005 as it is described by Judah on
http://www.iunknown.com/2007/08/ironruby-on-rub.html. But adding a main to the
ironruby project and executing it as a console application gives me the
exception below. Why is that? I also recognize that using the
Microsoft.Scriptin.dll that is build from VS2005 throws this exception when
being used in another project. The same dll compiled with rake works fine.

THIRD ISSUE

============================
I don''t know if this is a bug. Using split() with the standard ruby
command
line is just fine. But using it with rbx throws an error. I also tried the
variant with two parameters. Same issue. 

 

C:\>irb

irb(main):001:0> s = ''hello world''

=> "hello world"

irb(main):002:0> t = s.split('' '')

=> ["hello", "world"]

irb(main):003:0> exit

[Ironruby-core] Ruby code from C-Sharp; String.split() with rbx

1)      Currently there is not. What you need is to execute the code against a
binding object. This feature should be available as soon as eval is implemented
and some refactoring takes place in DLR hosting API. Both are on my TODO list.

2)      Our CLR assembly loader is not working right. I think a similar bug has
already been filed. It''s on my TODO list with high priority.

As for the strong name validation error, did you build under External Debug
configuration? John should know more about this.

3)      The overload taking a separator is not implemented yet.

[Ironruby-core] Present and Future of IronRuby

Hi,

 

following up on this forum post
(http://rubyforge.org/forum/forum.php?thread_id=17543&forum_id=17159) :

I recognized that a few things I tried to use in IronRuby ar not yet fully
supported (e.g., rand, File, Time). Is there a list available what is not
working or what is working right now? And is there maybe kind of a schedule
available when the community can expect what to be supported?

 

That would be of much help. Otherwise I am thinking about a script converter
for now, converting normal ruby scripts to IronRuby.

 

Thanks

Cheers

Stefan

[Ironruby-core] Present and Future of IronRuby

Hi Stefan,

The easiest way to see this is to look in the IronRuby sources under the
Builtins folder. There are a lot of things implemented to varying degrees of
completeness. The classes we focused on so far are Array, Hash, Enumerable,
Comparable, and Dir, plus a large part of String. A lot of other stuff was
filled in as needed to test those classes (e.g. Range implements
"each" so all of the Enumerable methods should work on ranges).

File IO is pretty high on the list of things to implement next. Time is also up
there because it''s used by File :). I''m not sure where
we''ll go after that... our Fearless Leader (John Lam) might have some
insight.

Cheers,
John M.
